+ xfs: fix type confusion in xfs_ioc_swapext
+
+ Without this check, the following XFS_I invocations would return bad
+ pointers when used on non-XFS inodes (perhaps pointers into preceding
+ allocator chunks).
+
+ This could be used by an attacker to trick xfs_swap_extents into
+ performing locking operations on attacker-chosen structures in kernel
+ memory, potentially leading to code execution in the kernel. (I have
+ not investigated how likely this is to be usable for an attack in
+ practice.)

+ apparmor: fix oops, validate buffer size in apparmor_setprocattr()
+
+ When proc_pid_attr_write() was changed to use memdup_user apparmor's
+ (interface violating) assumption that the setprocattr buffer was always
+ a single page was violated.
+
+ The size test is not strictly speaking needed as proc_pid_attr_write()
+ will reject anything larger, but for the sake of robustness we can keep
+ it in.
+
+ SMACK and SELinux look safe to me, but somebody else should probably
+ have a look just in case.
+
+ Based on original patch from Vegard Nossum <vegard.nossum@oracle.com>
+ modified for the case that apparmor provides null termination.

+
+ ovl: warn instead of error if d_type is not supported
+
+ overlay needs underlying fs to support d_type. Recently I put in a
+ patch in to detect this condition and started failing mount if
+ underlying fs did not support d_type.
+
+ But this breaks existing configurations over kernel upgrade. Those who
+ are running docker (partially broken configuration) with xfs not
+ supporting d_type, are surprised that after kernel upgrade docker does
+ not run anymore.
+
+ https://github.com/docker/docker/issues/22937#issuecomment-229881315
+
+ So instead of erroring out, detect broken configuration and warn
+ about it. This should allow existing docker setups to continue
+ working after kernel upgrade.

+ Fix bug in RBAC learning reported by Andrew Flannery
+ Nolog/noaudit-type capability checks were handled in a separate
+ function which did not check if the requestor had the capability in
+ their effective set. This would cause privileged processes to be
+ denied use of their capabilities in the small number of instances
+ these kinds of checks were used (for ptrace_may_access() etc, which
+ get used in deciding if privileged processes can bypass /proc
+ restrictions) only when RBAC learning was enabled on the process.
+
+ Remove some code duplication in the process of fixing the bug.

+ USB: usbip: fix potential out-of-bounds write
+
+ Fix potential out-of-bounds write to urb->transfer_buffer
+ usbip handles network communication directly in the kernel. When receiving a
+ packet from its peer, usbip code parses headers according to protocol. As
+ part of this parsing urb->actual_length is filled. Since the input for
+ urb->actual_length comes from the network, it should be treated as untrusted.
+ Any entity controlling the network may put any value in the input and the
+ preallocated urb->transfer_buffer may not be large enough to hold the data.
+ Thus, the malicious entity is able to write arbitrary data to kernel memory.

+
+ Because we miss to wipe the remainder of i->addr[] in packet_mc_add(),

+ ipv6: Count in extension headers in skb->network_header
+
+ When sending a UDPv6 message longer than MTU, account for the length
+ of fragmentable IPv6 extension headers in skb->network_header offset.
+ Same as we do in alloc_new_skb path in __ip6_append_data().
+
+ This ensures that later on __ip6_make_skb() will make space in
+ headroom for fragmentable extension headers:
+
+ /* move skb->data to ip header from ext header */
+ if (skb->data < skb_network_header(skb))
+ __skb_pull(skb, skb_network_offset(skb));

+ complain:
+
+ [ 284.440294] INFO: trying to register non-static key.

+
+ However, it also helps fixing a preexisting problem, which is why this
+ patch is also good for stable kernels: kvm_create_vm was incrementing
+ current->mm->mm_count but not decrementing it at the out_err label (in
+ case kvm_init_mmu_notifier failed). The new initialization order makes
+ it possible to add the required mmdrop without adding a new error label.

+ fs/coredump: prevent fsuid=0 dumps into user-controlled directories
+
+ This commit fixes the following security hole affecting systems where
+ all of the following conditions are fulfilled:
+
+ - The fs.suid_dumpable sysctl is set to 2.
+ - The kernel.core_pattern sysctl's value starts with "/". (Systems
+ where kernel.core_pattern starts with "|/" are not affected.)
+ - Unprivileged user namespace creation is permitted. (This is
+ true on Linux >=3.8, but some distributions disallow it by
+ default using a distro patch.)
+
+ Under these conditions, if a program executes under secure exec rules,
+ causing it to run with the SUID_DUMP_ROOT flag, then unshares its user
+ namespace, changes its root directory and crashes, the coredump will be
+ written using fsuid=0 and a path derived from kernel.core_pattern - but
+ this path is interpreted relative to the root directory of the process,
+ allowing the attacker to control where a coredump will be written with
+ root privileges.
+
+ To fix the security issue, always interpret core_pattern for dumps that
+ are written under SUID_DUMP_ROOT relative to the root directory of init.

+ ALSA: timer: Use mod_timer() for rearming the system timer
+
+ ALSA system timer backend stops the timer via del_timer() without sync

+ ext4: fix races of writeback with punch hole and zero range
+
+ When doing delayed allocation, update of on-disk inode size is postponed
+ until IO submission time. However hole punch or zero range fallocate
+ calls can end up discarding the tail page cache page and thus on-disk
+ inode size would never be properly updated.
+
+ Make sure the on-disk inode size is updated before truncating page

+
+ ext4: fix races between buffered IO and collapse / insert range
+
+ Current code implementing FALLOC_FL_COLLAPSE_RANGE and
+ FALLOC_FL_INSERT_RANGE is prone to races with buffered writes and page
+ faults. If buffered write or write via mmap manages to squeeze between
+ filemap_write_and_wait_range() and truncate_pagecache() in the fallocate
+ implementations, the written data is simply discarded by
+ truncate_pagecache() although it should have been shifted.
+
+ Fix the problem by moving filemap_write_and_wait_range() call inside
+ i_mutex and i_mmap_sem. That way we are protected against races with
+ both buffered writes and page faults.

+ Currently ext4_alloc_file_blocks() was handling protection against

+
+ ext4: fix races between page faults and hole punching
+
+ Currently, page faults and hole punching are completely unsynchronized.
+ This can result in page fault faulting in a page into a range that we
+ are punching after truncate_pagecache_range() has been called and thus
+ we can end up with a page mapped to disk blocks that will be shortly
+ freed. Filesystem corruption will shortly follow. Note that the same
+ race is avoided for truncate by checking page fault offset against
+ i_size but there isn't similar mechanism available for punching holes.
+
+ Fix the problem by creating new rw semaphore i_mmap_sem in inode and
+ grab it for writing over truncate, hole punching, and other functions
+ removing blocks from extent tree and for read over page faults. We
+ cannot easily use i_data_sem for this since that ranks below transaction
+ start and we need something ranking above it so that it can be held over
+ the whole truncate / hole punching operation. Also remove various
+ workarounds we had in the code to reduce race window when page fault
+ could have created pages with stale mapping information.

+ PKCS#7: pkcs7_validate_trust(): initialize the _trusted output argument
+
+ Despite what the DocBook comment to pkcs7_validate_trust() says, the
+ *_trusted argument is never set to false.
+
+ pkcs7_validate_trust() only positively sets *_trusted upon encountering
+ a trusted PKCS#7 SignedInfo block.
+
+ This is quite unfortunate since its callers, system_verify_data() for
+ example, depend on pkcs7_validate_trust() clearing *_trusted on non-trust.
+
+ Indeed, UBSAN splats when attempting to load the uninitialized local
+ variable 'trusted' from system_verify_data() in pkcs7_validate_trust():
+

+ netfilter: x_tables: fix unconditional helper
+
+ Ben Hawkes says:
+
+ In the mark_source_chains function (net/ipv4/netfilter/ip_tables.c) it
+ is possible for a user-supplied ipt_entry structure to have a large
+ next_offset field. This field is not bounds checked prior to writing a
+ counter value at the supplied offset.
+
+ Problem is that mark_source_chains should not have been called --
+ the rule doesn't have a next entry, so its supposed to return
+ an absolute verdict of either ACCEPT or DROP.
+
+ However, the function conditional() doesn't work as the name implies.
+ It only checks that the rule is using wildcard address matching.
+
+ However, an unconditional rule must also not be using any matches
+ (no -m args).
+
+ The underflow validator only checked the addresses, therefore
+ passing the 'unconditional absolute verdict' test, while
+ mark_source_chains also tested for presence of matches, and thus
+ proceeeded to the next (not-existent) rule.
+
+ Unify this so that all the callers have same idea of 'unconditional rule'.

+ mm/filemap: generic_file_read_iter(): check for zero reads unconditionally
+
+ If
+ - generic_file_read_iter() gets called with a zero read length,
+ - the read offset is at a page boundary,
+ - IOCB_DIRECT is not set
+ - and the page in question hasn't made it into the page cache yet,
+ then do_generic_file_read() will trigger a readahead with a req_size hint
+ of zero.
+
+ Since roundup_pow_of_two(0) is undefined, UBSAN reports
+
+ UBSAN: Undefined behaviour in include/linux/log2.h:63:13
+ shift exponent 64 is too large for 64-bit type 'long unsigned int'

+
+ The net effect is that the initial readahead size is arch dependent for

+
+ 1UL << (sizeof(unsigned long) * 8)
+
+ evaluates to 1 on x86 while its result is 0 on ARMv7, the initial readahead
+ size becomes 4 on the former and 0 on the latter.
+
+ What's more, whether or not the file access timestamp is updated for zero
+ length reads is decided differently for the two cases of IOCB_DIRECT
+ being set or cleared: in the first case, generic_file_read_iter()
+ explicitly skips updating that timestamp while in the latter case, it is
+ always updated through the call to do_generic_file_read().
+
+ According to POSIX, zero length reads "do not modify the last data access
+ timestamp" and thus, the IOCB_DIRECT behaviour is POSIXly correct.
+
+ Let generic_file_read_iter() unconditionally check the requested read
+ length at its entry and return immediately with success if it is zero.

+ crypto: marvell/cesa - fix memory leak
+
+ Crypto requests are not guaranteed to be finalized (->final() call),
+ and can be freed at any moment, without getting any notification from
+ the core. This can lead to memory leaks of the ->cache buffer.
+
+ Make this buffer part of the request object, and allocate an extra buffer
+ from the DMA cache pool when doing DMA operations.
+
+ As a side effect, this patch also fixes another bug related to cache
+ allocation and DMA operations. When the core allocates a new request and
+ import an existing state, a cache buffer can be allocated (depending
+ on the state). The problem is, at that very moment, we don't know yet
+ whether the request will use DMA or not, and since everything is
+ likely to be initialized to zero, mv_cesa_ahash_alloc_cache() thinks it
+ should allocate a buffer for standard operation. But when
+ mv_cesa_ahash_free_cache() is called, req->type has been set to
+ CESA_DMA_REQ in the meantime, thus leading to an invalind dma_pool_free()
+ call (the buffer passed in argument has not been allocated from the pool).

+ ipv4: Don't do expensive useless work during inetdev destroy.
+
+ When an inetdev is destroyed, every address assigned to the interface
+ is removed. And in this scenerio we do two pointless things which can
+ be very expensive if the number of assigned interfaces is large:
+
+ 1) Address promotion. We are deleting all addresses, so there is no
+ point in doing this.
+
+ 2) A full nf conntrack table purge for every address. We only need to
+ do this once, as is already caught by the existing
+ masq_dev_notifier so masq_inet_event() can skip this.

+ sctp: fix copying more bytes than expected in sctp_add_bind_addr
+
+ Dmitry reported that sctp_add_bind_addr may read more bytes than
+ expected in case the parameter is a IPv4 addr supplied by the user
+ through calls such as sctp_bindx_add(), because it always copies
+ sizeof(union sctp_addr) while the buffer may be just a struct
+ sockaddr_in, which is smaller.
+
+ This patch then fixes it by limiting the memcpy to the min between the
+ union size and a (new parameter) provided addr size. Where possible this
+ parameter still is the size of that union, except for reading from
+ user-provided buffers, which then it accounts for protocol type.

+ KVM: MMU: fix ept=0/pte.u=1/pte.w=0/CR0.WP=0/CR4.SMEP=1/EFER.NX=0 combo
+
+ Yes, all of these are needed. :) This is admittedly a bit odd, but
+ kvm-unit-tests access.flat tests this if you run it with "-cpu host"
+ and of course ept=0.
+
+ KVM runs the guest with CR0.WP=1, so it must handle supervisor writes
+ specially when pte.u=1/pte.w=0/CR0.WP=0. Such writes cause a fault
+ when U=1 and W=0 in the SPTE, but they must succeed because CR0.WP=0.
+ When KVM gets the fault, it sets U=0 and W=1 in the shadow PTE and
+ restarts execution. This will still cause a user write to fault, while
+ supervisor writes will succeed. User reads will fault spuriously now,
+ and KVM will then flip U and W again in the SPTE (U=1, W=0). User reads
+ will be enabled and supervisor writes disabled, going back to the
+ originary situation where supervisor writes fault spuriously.
+
+ When SMEP is in effect, however, U=0 will enable kernel execution of
+ this page. To avoid this, KVM also sets NX=1 in the shadow PTE together
+ with U=0. If the guest has not enabled NX, the result is a continuous
+ stream of page faults due to the NX bit being reserved.
+
+ The fix is to force EFER.NX=1 even if the CPU is taking care of the EFER
+ switch. (All machines with SMEP have the CPU_LOAD_IA32_EFER vm-entry
+ control, so they do not use user-return notifiers for EFER---if they did,
+ EFER.NX would be forced to the same value as the host).
+
+ There is another bug in the reserved bit check, which I've split to a
+ separate patch for easier application to stable kernels.

+
+ KVM: MMU: fix reserved bit check for ept=0/CR0.WP=0/CR4.SMEP=1/EFER.NX=0
+

+ CR0.WP=1. These pages' SPTEs flip continuously between two states:
+ U=1/W=0 (user and supervisor reads allowed, supervisor writes not allowed)
+ and U=0/W=1 (supervisor reads and writes allowed, user writes not allowed).
+
+ When SMEP is in effect, however, U=0 will enable kernel execution of
+ this page. To avoid this, KVM also sets NX=1 in the shadow PTE together
+ with U=0, making the two states U=1/W=0/NX=gpte.NX and U=0/W=1/NX=1.
+ When guest EFER has the NX bit cleared, the reserved bit check thinks
+ that the latter state is invalid; teach it that the smep_andnot_wp case
+ will also use the NX bit of SPTEs.

+
+ x86/fpu: Fix eager-FPU handling on legacy FPU machines
+
+ i486 derived cores like Intel Quark support only the very old,
+ legacy x87 FPU (FSAVE/FRSTOR, CPUID bit FXSR is not set), and
+ our FPU code wasn't handling the saving and restoring there
+ properly in the 'eagerfpu' case.
+
+ So after we made eagerfpu the default for all CPU types:
+
+ 58122bf1d856 x86/fpu: Default eagerfpu=on on all CPUs
+
+ these old FPU designs broke. First, Andy Shevchenko reported a splat:
+
+ WARNING: CPU: 0 PID: 823 at arch/x86/include/asm/fpu/internal.h:163 fpu__clear+0x8c/0x160
+
+ which was us trying to execute FXRSTOR on those machines even though
+ they don't support it.
+
+ After taking care of that, Bryan O'Donoghue reported that a simple FPU
+ test still failed because we weren't initializing the FPU state properly
+ on those machines.
+
+ Take care of all that.

+ As reported by Jann Horn, chroot scenarios where the chrooting application
+ brings in a directory fd can be used to access any file outside of the chroot
+ via *at syscalls. To maintain compatibility with Chromium and other apps,
+ we specifically only disallow relative accesses off a directory fd when the
+ final path is not located under that directory described by the fd and exists
+ outside of the chroot. This additional restriction will exist under the
+ current GRKERNSEC_CHROOT_FCHDIR option.

+ Update the daemon check in handling of anti-bruteforcing of suid binaries
+ by GRKERNSEC_BRUTE to prevent a bypass reported by Jann Horn where one
+ could create unprivileged copies of the suid binary via ptrace, inject
+ code into them, and fork+exec a privileged copy. A crash then in the
+ privileged copy would trigger the daemon detection which could be avoided
+ by simply terminating the original process. Defeat this by using our
+ is_privileged_binary() function against the task's mm->binfmt->file to detect
+ an fscaps-enabled or suid/sgid binary being involved.
+
+ Also update the RBAC RES_CRASH code to use is_privileged_binary().

+ bpf: fix branch offset adjustment on backjumps after patching ctx expansion
+
+ When ctx access is used, the kernel often needs to expand/rewrite
+ instructions, so after that patching, branch offsets have to be
+ adjusted for both forward and backward jumps in the new eBPF program,
+ but for backward jumps it fails to account the delta. Meaning, for
+ example, if the expansion happens exactly on the insn that sits at
+ the jump target, it doesn't fix up the back jump offset.
+
+ Analysis on what the check in adjust_branches() is currently doing:
+
+ /* adjust offset of jmps if necessary */
+ if (i < pos && i + insn->off + 1 > pos)
+ insn->off += delta;
+ else if (i > pos && i + insn->off + 1 < pos)
+ insn->off -= delta;
+
+ First condition (forward jumps):
+
+ Before: After:
+
+ insns[0] insns[0]
+ insns[1] <--- i/insn insns[1] <--- i/insn
+ insns[2] <--- pos insns[P] <--- pos
+ insns[3] insns[P] `------| delta
+ insns[4] <--- target_X insns[P] `-----|
+ insns[5] insns[3]
+ insns[4] <--- target_X
+ insns[5]
+
+ First case is if we cross pos-boundary and the jump instruction was
+ before pos. This is handeled correctly. I.e. if i == pos, then this
+ would mean our jump that we currently check was the patchlet itself
+ that we just injected. Since such patchlets are self-contained and
+ have no awareness of any insns before or after the patched one, the
+ delta is correctly not adjusted. Also, for the second condition in
+ case of i + insn->off + 1 == pos, means we jump to that newly patched
+ instruction, so no offset adjustment are needed. That part is correct.
+
+ Second condition (backward jumps):
+
+ Before: After:
+
+ insns[0] insns[0]
+ insns[1] <--- target_X insns[1] <--- target_X
+ insns[2] <--- pos <-- target_Y insns[P] <--- pos <-- target_Y
+ insns[3] insns[P] `------| delta
+ insns[4] <--- i/insn insns[P] `-----|
+ insns[5] insns[3]
+ insns[4] <--- i/insn
+ insns[5]
+
+ Second interesting case is where we cross pos-boundary and the jump
+ instruction was after pos. Backward jump with i == pos would be
+ impossible and pose a bug somewhere in the patchlet, so the first
+ condition checking i > pos is okay only by itself. However, i +
+ insn->off + 1 < pos does not always work as intended to trigger the
+ adjustment. It works when jump targets would be far off where the
+ delta wouldn't matter. But, for example, where the fixed insn->off
+ before pointed to pos (target_Y), it now points to pos + delta, so
+ that additional room needs to be taken into account for the check.
+ This means that i) both tests here need to be adjusted into pos + delta,
+ and ii) for the second condition, the test needs to be <= as pos
+ itself can be a target in the backjump, too.

+ EVM: Use crypto_memneq() for digest comparisons
+
+ This patch fixes vulnerability CVE-2016-2085. The problem exists
+ because the vm_verify_hmac() function includes a use of memcmp().
+ Unfortunately, this allows timing side channel attacks; specifically
+ a MAC forgery complexity drop from 2^128 to 2^12. This patch changes
+ the memcmp() to the cryptographically safe crypto_memneq().

+ 3. sys_clock_nanosleep
+
+ This can happen on MIPS32 and ARM32 with "Full dynticks CPU time accounting"

+

+
+ radix-tree: fix race in gang lookup
+
+ If the indirect_ptr bit is set on a slot, that indicates we need to redo
+ the lookup. Introduce a new function radix_tree_iter_retry() which
+ forces the loop to retry the lookup by setting 'slot' to NULL and
+ turning the iterator back to point at the problematic entry.
+
+ This is a pretty rare problem to hit at the moment; the lookup has to
+ race with a grow of the radix tree from a height of 0. The consequences
+ of hitting this race are that gang lookup could return a pointer to a
+ radix_tree_node instead of a pointer to whatever the user had inserted
+ in the tree.

+ unix: correctly track in-flight fds in sending process user_struct
+
+ The commit referenced in the Fixes tag incorrectly accounted the number
+ of in-flight fds over a unix domain socket to the original opener
+ of the file-descriptor. This allows another process to arbitrary
+ deplete the original file-openers resource limit for the maximum of
+ open files. Instead the sending processes and its struct cred should
+ be credited.
+
+ To do so, we add a reference counted struct user_struct pointer to the
+ scm_fp_list and use it to account for the number of inflight unix fds.

+ fs/hugetlbfs/inode.c: fix bugs in hugetlb_vmtruncate_list()
+
+ Hillf Danton noticed bugs in the hugetlb_vmtruncate_list routine. The
+ argument end is of type pgoff_t. It was being converted to a vaddr
+ offset and passed to unmap_hugepage_range. However, end was also being
+ used as an argument to the vma_interval_tree_foreach controlling loop.
+ In addition, the conversion of end to vaddr offset was incorrect.
+
+ hugetlb_vmtruncate_list is called as part of a file truncate or
+ fallocate hole punch operation.
+
+ When truncating a hugetlbfs file, this bug could prevent some pages from
+ being unmapped. This is possible if there are multiple vmas mapping the
+ file, and there is a sufficiently sized hole between the mappings. The
+ size of the hole between two vmas (A,B) must be such that the starting
+ virtual address of B is greater than (ending virtual address of A <<
+ PAGE_SHIFT). In this case, the pages in B would not be unmapped. If
+ pages are not properly unmapped during truncate, the following BUG is
+ hit:
+
+ kernel BUG at fs/hugetlbfs/inode.c:428!
+
+ In the fallocate hole punch case, this bug could prevent pages from
+ being unmapped as in the truncate case. However, for hole punch the
+ result is that unmapped pages will not be removed during the operation.
+ For hole punch, it is also possible that more pages than desired will be
+ unmapped. This unnecessary unmapping will cause page faults to
+ reestablish the mappings on subsequent page access.

+ ALSA: timer: Fix leftover link at closing
+
+ In ALSA timer core, the active timer instance is managed in
+ active_list linked list. Each element is added / removed dynamically
+ at timer start, stop and in timer interrupt. The problem is that
+ snd_timer_interrupt() has a thinko and leaves the element in
+ active_list when it's the last opened element. This eventually leads
+ to list corruption or use-after-free error.
+
+ This hasn't been revealed because we used to delete the list forcibly
+ in snd_timer_stop() in the past. However, the recent fix avoids the
+ double-stop behavior (in commit [f784beb75ce8: ALSA: timer: Fix link
+ corruption due to double start or stop]), and this leak hits reality.
+
+ This patch fixes the link management in snd_timer_interrupt(). Now it
+ simply unlinks no matter which stream is.

+
+ Helper radix_tree_iter_retry() resets next_index to the current index.
+ In following radix_tree_next_slot current chunk size becomes zero. This

+
+ Tagged iterator is fine because retry happens only at slot 0 where tag

+Author: Matt Fleming <matt@codeblueprint.co.uk>
+Date: Fri Jan 29 11:36:10 2016 +0000
+
+ x86/mm/pat: Avoid truncation when converting cpa->numpages to address
+
+ There are a couple of nasty truncation bugs lurking in the pageattr
+ code that can be triggered when mapping EFI regions, e.g. when we pass
+ a cpa->pgd pointer. Because cpa->numpages is a 32-bit value, shifting
+ left by PAGE_SHIFT will truncate the resultant address to 32-bits.
+
+ Viorel-Cătălin managed to trigger this bug on his Dell machine that
+ provides a ~5GB EFI region which requires 1236992 pages to be mapped.
+ When calling populate_pud() the end of the region gets calculated
+ incorrectly in the following buggy expression,
+
+ end = start + (cpa->numpages << PAGE_SHIFT);
+
+ And only 188416 pages are mapped. Next, populate_pud() gets invoked
+ for a second time because of the loop in __change_page_attr_set_clr(),
+ only this time no pages get mapped because shifting the remaining
+ number of pages (1048576) by PAGE_SHIFT is zero. At which point the
+ loop in __change_page_attr_set_clr() spins forever because we fail to
+ map progress.
+
+ Hitting this bug depends very much on the virtual address we pick to
+ map the large region at and how many pages we map on the initial run
+ through the loop. This explains why this issue was only recently hit
+ with the introduction of commit
+
+ a5caa209ba9c ("x86/efi: Fix boot crash by mapping EFI memmap
+ entries bottom-up at runtime, instead of top-down")
+
+ It's interesting to note that safe uses of cpa->numpages do exist in
+ the pageattr code. If instead of shifting ->numpages we multiply by
+ PAGE_SIZE, no truncation occurs because PAGE_SIZE is a UL value, and
+ so the result is unsigned long.
+
+ To avoid surprises when users try to convert very large cpa->numpages
+ values to addresses, change the data type from 'int' to 'unsigned
+ long', thereby making it suitable for shifting by PAGE_SHIFT without
+ any type casting.
+
+ The alternative would be to make liberal use of casting, but that is
+ far more likely to cause problems in the future when someone adds more
+ code and fails to cast properly; this bug was difficult enough to
+ track down in the first place.

+ tcp: fix zero cwnd in tcp_cwnd_reduction
+
+ Patch 3759824da87b ("tcp: PRR uses CRB mode by default and SS mode
+ conditionally") introduced a bug that cwnd may become 0 when both
+ inflight and sndcnt are 0 (cwnd = inflight + sndcnt). This may lead
+ to a div-by-zero if the connection starts another cwnd reduction
+ phase by setting tp->prior_cwnd to the current cwnd (0) in
+ tcp_init_cwnd_reduction().
+
+ To prevent this we skip PRR operation when nothing is acked or
+ sacked. Then cwnd must be positive in all cases as long as ssthresh
+ is positive:
+
+ 1) The proportional reduction mode
+ inflight > ssthresh > 0
+
+ 2) The reduction bound mode
+ a) inflight == ssthresh > 0
+
+ b) inflight < ssthresh
+ sndcnt > 0 since newly_acked_sacked > 0 and inflight < ssthresh
+
+ Therefore in all cases inflight and sndcnt can not both be 0.
+ We check invalid tp->prior_cwnd to avoid potential div0 bugs.
+
+ In reality this bug is triggered only with a sequence of less common
+ events. For example, the connection is terminating an ECN-triggered
+ cwnd reduction with an inflight 0, then it receives reordered/old
+ ACKs or DSACKs from prior transmission (which acks nothing). Or the
+ connection is in fast recovery stage that marks everything lost,
+ but fails to retransmit due to local issues, then receives data
+ packets from other end which acks nothing.

+ pptp: fix illegal memory access caused by multiple bind()s
+
+ Several times already this has been reported as kasan reports caused by
+ syzkaller and trinity and people always looked at RCU races, but it is
+ much more simple. :)
+
+ In case we bind a pptp socket multiple times, we simply add it to
+ the callid_sock list but don't remove the old binding. Thus the old
+ socket stays in the bucket with unused call_id indexes and doesn't get
+ cleaned up. This causes various forms of kasan reports which were hard
+ to pinpoint.
+
+ Simply don't allow multiple binds and correct error handling in
+ pptp_bind. Also keep sk_state bits in place in pptp_connect.

+ ipv4+ipv6: Make INET*_ESP select CRYPTO_ECHAINIV
+
+ The ESP algorithms using CBC mode require echainiv. Hence INET*_ESP have
+ to select CRYPTO_ECHAINIV in order to work properly. This solves the
+ issues caused by a misconfiguration as described in [1].
+ The original approach, patching crypto/Kconfig was turned down by
+ Herbert Xu [2].

+ netfilter: nf_conntrack: use safer way to lock all buckets
+
+ When we need to lock all buckets in the connection hashtable we'd attempt to
+ lock 1024 spinlocks, which is way more preemption levels than supported by
+ the kernel. Furthermore, this behavior was hidden by checking if lockdep is
+ enabled, and if it was - use only 8 buckets(!).
+
+ Fix this by using a global lock and synchronize all buckets on it when we
+ need to lock them all. This is pretty heavyweight, but is only done when we
+ need to resize the hashtable, and that doesn't happen often enough (or at all).

+ pipe: limit the per-user amount of pages allocated in pipes
+
+ On no-so-small systems, it is possible for a single process to cause an
+ OOM condition by filling large pipes with data that are never read. A
+ typical process filling 4000 pipes with 1 MB of data will use 4 GB of
+ memory. On small systems it may be tricky to set the pipe max size to
+ prevent this from happening.
+
+ This patch makes it possible to enforce a per-user soft limit above
+ which new pipes will be limited to a single page, effectively limiting
+ them to 4 kB each, as well as a hard limit above which no new pipes may
+ be created for this user. This has the effect of protecting the system
+ against memory abuse without hurting other users, and still allowing
+ pipes to work correctly though with less data at once.
+
+ The limit are controlled by two new sysctls : pipe-user-pages-soft, and
+ pipe-user-pages-hard. Both may be disabled by setting them to zero. The
+ default soft limit allows the default number of FDs per process (1024)
+ to create pipes of the default size (64kB), thus reaching a limit of 64MB
+ before starting to create only smaller pipes. With 256 processes limited
+ to 1024 FDs each, this results in 1024*64kB + (256*1024 - 1024) * 4kB =
+ 1084 MB of memory allocated for a user. The hard limit is disabled by
+ default to avoid breaking existing applications that make intensive use
+ of pipes (eg: for splicing).

+ This replaces all code in fs/compat_ioctl.c that translated

+ what the ioctl command number is. The accidental
+ invocation of an unlocked_ioctl handler that unexpectedly
+ calls copy_to_user could be a severe security issue.

+
+ compat_ioctl: don't look up the fd twice
+
+ In code in fs/compat_ioctl.c that translates ioctl arguments
+ into a in-kernel structure, then performs sys_ioctl, possibly
+ under set_fs(KERNEL_DS), this commit changes the sys_ioctl
+ calls to do_ioctl calls. do_ioctl is a new function that does
+ the same thing as sys_ioctl, but doesn't look up the fd again.
+
+ This change is made to avoid (potential) security issues
+ because of ioctl handlers that accept one of the ioctl
+ commands I2C_FUNCS, VIDEO_GET_EVENT, MTIOCPOS, MTIOCGET,
+ TIOCGSERIAL, TIOCSSERIAL, RTC_IRQP_READ, RTC_EPOCH_READ.
+ This can happen for multiple reasons:
+
+ - The ioctl command number could be reused.
+ - The ioctl handler might not check the full ioctl
+ command. This is e.g. true for drm_ioctl.
+ - The ioctl handler is very special, e.g. cuse_file_ioctl
+
+ The real issue is that set_fs(KERNEL_DS) is used here,
+ but that's fixed in a separate commit
+ "compat_ioctl: don't call do_ioctl under set_fs(KERNEL_DS)".
+
+ This change mitigates potential security issues by
+ preventing a race that permits invocation of
+ unlocked_ioctl handlers under KERNEL_DS through compat
+ code even if a corresponding compat_ioctl handler exists.
+
+ So far, no way has been identified to use this to damage
+ kernel memory without having CAP_SYS_ADMIN in the init ns
+ (with the capability, doing reads/writes at arbitrary
+ kernel addresses should be easy through CUSE's ioctl
+ handler with FUSE_IOCTL_UNRESTRICTED set).

+ ALSA: hrtimer: Fix stall by hrtimer_cancel()
+
+ hrtimer_cancel() waits for the completion from the callback, thus it
+ must not be called inside the callback itself. This was already a
+ problem in the past with ALSA hrtimer driver, and the early commit
+ [fcfdebe70759: ALSA: hrtimer - Fix lock-up] tried to address it.
+
+ However, the previous fix is still insufficient: it may still cause a
+ lockup when the ALSA timer instance reprograms itself in its callback.
+ Then it invokes the start function even in snd_timer_interrupt() that
+ is called in hrtimer callback itself, results in a CPU stall. This is
+ no hypothetical problem but actually triggered by syzkaller fuzzer.
+
+ This patch tries to fix the issue again. Now we call
+ hrtimer_try_to_cancel() at both start and stop functions so that it
+ won't fall into a deadlock, yet giving some chance to cancel the queue
+ if the functions have been called outside the callback. The proper
+ hrtimer_cancel() is called in anyway at closing, so this should be
+ enough.

+ ALSA: timer: Harden slave timer list handling
+
+ A slave timer instance might be still accessible in a racy way while
+ operating the master instance as it lacks of locking. Since the
+ master operation is mostly protected with timer->lock, we should cope
+ with it while changing the slave instance, too. Also, some linked
+ lists (active_list and ack_list) of slave instances aren't unlinked
+ immediately at stopping or closing, and this may lead to unexpected
+ accesses.
+
+ This patch tries to address these issues. It adds spin lock of
+ timer->lock (either from master or slave, which is equivalent) in a
+ few places. For avoiding a deadlock, we ensure that the global
+ slave_active_lock is always locked at first before each timer lock.
+
+ Also, ack and active_list of slave instances are properly unlinked at
+ snd_timer_stop() and snd_timer_close().
+
+ Last but not least, remove the superfluous call of _snd_timer_stop()
+ at removing slave links. This is a noop, and calling it may confuse
+ readers wrt locking. Further cleanup will follow in a later patch.
+
+ Actually we've got reports of use-after-free by syzkaller fuzzer, and
+ this hopefully fixes these issues.

+
+ It was seen that defective configurations of openvswitch could overwrite

+

+ As pointed out by Jann Horn, some distros are starting to circumvent

+ be banned before a reboot is required. If more are banned, a panic

+ sctp: fix use-after-free in pr_debug statement
+
+ Dmitry Vyukov reported a use-after-free in the code expanded by the
+ macro debug_post_sfx, which is caused by the use of the asoc pointer
+ after it was freed within sctp_side_effect() scope.
+
+ This patch fixes it by allowing sctp_side_effect to clear that asoc
+ pointer when the TCB is freed.
+
+ As Vlad explained, we also have to cover the SCTP_DISPOSITION_ABORT case
+ because it will trigger DELETE_TCB too on that same loop.
+
+ Also, there were places issuing SCTP_CMD_INIT_FAILED and ASSOC_FAILED
+ but returning SCTP_DISPOSITION_CONSUME, which would fool the scheme
+ above. Fix it by returning SCTP_DISPOSITION_ABORT instead.
+
+ The macro is already prepared to handle such NULL pointer.

+ RDS: fix race condition when sending a message on unbound socket
+
+ commit 8c7188b23474cca017b3ef354c4a58456f68303a upstream.
+
+ Sasha's found a NULL pointer dereference in the RDS connection code when
+ sending a message to an apparently unbound socket. The problem is caused
+ by the code checking if the socket is bound in rds_sendmsg(), which checks
+ the rs_bound_addr field without taking a lock on the socket. This opens a
+ race where rs_bound_addr is temporarily set but where the transport is not
+ in rds_bind(), leading to a NULL pointer dereference when trying to
+ dereference 'trans' in __rds_conn_create().
+
+ Vegard wrote a reproducer for this issue, so kindly ask him to share if
+ you're interested.
+
+ I cannot reproduce the NULL pointer dereference using Vegard's reproducer
+ with this patch, whereas I could without.
+
+ Complete earlier incomplete fix to CVE-2015-6937:
+

+ ftrace/module: Call clean up function when module init fails early
+
+ If the module init code fails after calling ftrace_module_init() and before
+ calling do_init_module(), we can suffer from a memory leak. This is because
+ ftrace_module_init() allocates pages to store the locations that ftrace
+ hooks are placed in the module text. If do_init_module() fails, it still
+ calls the MODULE_GOING notifiers which will tell ftrace to do a clean up of
+ the pages it allocated for the module. But if load_module() fails before
+ then, the pages allocated by ftrace_module_init() will never be freed.
+
+ Call ftrace_release_mod() on the module if load_module() fails before
+ getting to do_init_module().

+ mkiss: fix scribble on freed memory
+
+ commit d79f16c046086f4fe0d42184a458e187464eb83e fixed a user triggerable
+ scribble on free memory but added a new one which allows the user to
+ scribble even more and user controlled data into freed space.
+
+ As with 6pack we need to halt the queue before we free the buffers, because
+ the transmit logic is not protected by the semaphore.

+ 6pack: fix free memory scribbles
+
+ commit acf673a3187edf72068ee2f92f4dc47d66baed47 fixed a user triggerable free
+ memory scribble but in doing so replaced it with a different one that allows
+ the user to control the data and scribble even more.
+
+ sixpack_close is called by the tty layer in tty context. The tty context is
+ protected by sp_get() and sp_put(). However network layer activity via
+ sp_xmit() is not protected this way. We must therefore stop the queue
+ otherwise the user gets to dump a buffer mostly of their choice into freed
+ kernel pages.

+ af_unix: Fix splice-bind deadlock
+
+ On 2015/11/06, Dmitry Vyukov reported a deadlock involving the splice
+ system call and AF_UNIX sockets,
+
+ http://lists.openwall.net/netdev/2015/11/06/24
+
+ The situation was analyzed as
+
+ (a while ago) A: socketpair()
+ B: splice() from a pipe to /mnt/regular_file
+ does sb_start_write() on /mnt
+ C: try to freeze /mnt
+ wait for B to finish with /mnt
+ A: bind() try to bind our socket to /mnt/new_socket_name
+ lock our socket, see it not bound yet
+ decide that it needs to create something in /mnt
+ try to do sb_start_write() on /mnt, block (it's
+ waiting for C).
+ D: splice() from the same pipe to our socket
+ lock the pipe, see that socket is connected
+ try to lock the socket, block waiting for A
+ B: get around to actually feeding a chunk from
+ pipe to file, try to lock the pipe. Deadlock.
+
+ on 2015/11/10 by Al Viro,
+
+ http://lists.openwall.net/netdev/2015/11/10/4
+
+ The patch fixes this by removing the kern_path_create related code from
+ unix_mknod and executing it as part of unix_bind prior acquiring the
+ readlock of the socket in question. This means that A (as used above)
+ will sb_start_write on /mnt before it acquires the readlock, hence, it
+ won't indirectly block B which first did a sb_start_write and then
+ waited for a thread trying to acquire the readlock. Consequently, A
+ being blocked by C waiting for B won't cause a deadlock anymore
+ (effectively, both A and B acquire two locks in opposite order in the
+ situation described above).
+
+ Dmitry Vyukov(<dvyukov@google.com>) tested the original patch.

+
+ KEYS: Fix race between read and revoke
+
+ This fixes CVE-2015-7550.
+
+ There's a race between keyctl_read() and keyctl_revoke(). If the revoke
+ happens between keyctl_read() checking the validity of a key and the key's
+ semaphore being taken, then the key type read method will see a revoked key.
+
+ This causes a problem for the user-defined key type because it assumes in
+ its read method that there will always be a payload in a non-revoked key
+ and doesn't check for a NULL pointer.
+
+ Fix this by making keyctl_read() check the validity of a key after taking
+ semaphore instead of before.
+
+ I think the bug was introduced with the original keyrings code.
+
+ This was discovered by a multithreaded test program generated by syzkaller
+ (http://github.com/google/syzkaller). Here's a cleaned up version:
+
+ #include <sys/types.h>
+ #include <keyutils.h>
+ #include <pthread.h>
+ void *thr0(void *arg)
+ {
+ key_serial_t key = (unsigned long)arg;
+ keyctl_revoke(key);
+ return 0;
+ }
+ void *thr1(void *arg)
+ {
+ key_serial_t key = (unsigned long)arg;
+ char buffer[16];
+ keyctl_read(key, buffer, 16);
+ return 0;
+ }
+ int main()
+ {
+ key_serial_t key = add_key("user", "%", "foo", 3, KEY_SPEC_USER_KEYRING);
+ pthread_t th[5];
+ pthread_create(&th[0], 0, thr0, (void *)(unsigned long)key);
+ pthread_create(&th[1], 0, thr1, (void *)(unsigned long)key);
+ pthread_create(&th[2], 0, thr0, (void *)(unsigned long)key);
+ pthread_create(&th[3], 0, thr1, (void *)(unsigned long)key);

+
+ ptrace_has_cap() checks whether the current process should be
+ treated as having a certain capability for ptrace checks
+ against another process. Until now, this was equivalent to
+ has_ns_capability(current, target_ns, CAP_SYS_PTRACE).
+
+ However, if a root-owned process wants to enter a user
+ namespace for some reason without knowing who owns it and
+ therefore can't change to the namespace owner's uid and gid
+ before entering, as soon as it has entered the namespace,
+ the namespace owner can attach to it via ptrace and thereby
+ gain access to its uid and gid.
+
+ While it is possible for the entering process to switch to
+ the uid of a claimed namespace owner before entering,
+ causing the attempt to enter to fail if the claimed uid is
+ wrong, this doesn't solve the problem of determining an
+ appropriate gid.
+
+ With this change, the entering process can first enter the
+ namespace and then safely inspect the namespace's
+ properties, e.g. through /proc/self/{uid_map,gid_map},
+ assuming that the namespace owner doesn't have access to
+ uid 0.

+ - fixed __get_user on x86 to lie less about the size of the load, reported by peetaur (https://forums.grsecurity.net/viewtopic.php?f=3&t=4332)
+ - Emese fixed an intentional overflow caused by gcc, reported by saironiq (https://forums.grsecurity.net/viewtopic.php?f=3&t=4333)
+ - Emese fixed a false positive overflow report in the forcedeth driver, reported by fx3 (https://forums.grsecurity.net/viewtopic.php?t=4334)
+ - Emese fixed a false positive overflow report in KVM's emulator, reported by fx3 (https://forums.grsecurity.net/viewtopic.php?f=3&t=4336)
+ - Emese fixed the initify plugin to detect some captured use of __func__, reported by Rasmus Villemoes <linux@rasmusvillemoes.dk>
+ - constrained shmmax and shmall to avoid triggering size overflow checks, reported by Mathias Krause <minipli@ld-linux.so>
+ - the checker plugin can partially handle sparse's locking context annotations, it's context insensitive and thus not exactly useful for now, also see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59856

+
+ radix-tree: fix race in gang lookup
+
+ If the indirect_ptr bit is set on a slot, that indicates we need to redo
+ the lookup. Introduce a new function radix_tree_iter_retry() which
+ forces the loop to retry the lookup by setting 'slot' to NULL and
+ turning the iterator back to point at the problematic entry.
+
+ This is a pretty rare problem to hit at the moment; the lookup has to
+ race with a grow of the radix tree from a height of 0. The consequences
+ of hitting this race are that gang lookup could return a pointer to a
+ radix_tree_node instead of a pointer to whatever the user had inserted
+ in the tree.

+ unix: correctly track in-flight fds in sending process user_struct
+
+ The commit referenced in the Fixes tag incorrectly accounted the number
+ of in-flight fds over a unix domain socket to the original opener
+ of the file-descriptor. This allows another process to arbitrary
+ deplete the original file-openers resource limit for the maximum of
+ open files. Instead the sending processes and its struct cred should
+ be credited.
+
+ To do so, we add a reference counted struct user_struct pointer to the
+ scm_fp_list and use it to account for the number of inflight unix fds.

+ fs/hugetlbfs/inode.c: fix bugs in hugetlb_vmtruncate_list()
+
+ Hillf Danton noticed bugs in the hugetlb_vmtruncate_list routine. The
+ argument end is of type pgoff_t. It was being converted to a vaddr
+ offset and passed to unmap_hugepage_range. However, end was also being
+ used as an argument to the vma_interval_tree_foreach controlling loop.
+ In addition, the conversion of end to vaddr offset was incorrect.
+
+ hugetlb_vmtruncate_list is called as part of a file truncate or
+ fallocate hole punch operation.
+
+ When truncating a hugetlbfs file, this bug could prevent some pages from
+ being unmapped. This is possible if there are multiple vmas mapping the
+ file, and there is a sufficiently sized hole between the mappings. The
+ size of the hole between two vmas (A,B) must be such that the starting
+ virtual address of B is greater than (ending virtual address of A <<
+ PAGE_SHIFT). In this case, the pages in B would not be unmapped. If
+ pages are not properly unmapped during truncate, the following BUG is
+ hit:
+
+ kernel BUG at fs/hugetlbfs/inode.c:428!
+
+ In the fallocate hole punch case, this bug could prevent pages from
+ being unmapped as in the truncate case. However, for hole punch the
+ result is that unmapped pages will not be removed during the operation.
+ For hole punch, it is also possible that more pages than desired will be
+ unmapped. This unnecessary unmapping will cause page faults to
+ reestablish the mappings on subsequent page access.

+
+ ALSA: timer: Fix leftover link at closing
+
+ In ALSA timer core, the active timer instance is managed in
+ active_list linked list. Each element is added / removed dynamically
+ at timer start, stop and in timer interrupt. The problem is that
+ snd_timer_interrupt() has a thinko and leaves the element in
+ active_list when it's the last opened element. This eventually leads
+ to list corruption or use-after-free error.
+
+ This hasn't been revealed because we used to delete the list forcibly
+ in snd_timer_stop() in the past. However, the recent fix avoids the
+ double-stop behavior (in commit [f784beb75ce8: ALSA: timer: Fix link
+ corruption due to double start or stop]), and this leak hits reality.
+
+ This patch fixes the link management in snd_timer_interrupt(). Now it
+ simply unlinks no matter which stream is.

+ radix-tree: fix oops after radix_tree_iter_retry
+
+ Helper radix_tree_iter_retry() resets next_index to the current index.
+ In following radix_tree_next_slot current chunk size becomes zero. This
+ isn't checked and it tries to dereference null pointer in slot.
+
+ Tagged iterator is fine because retry happens only at slot 0 where tag

+Author: Matt Fleming <matt@codeblueprint.co.uk>

+
+ x86/mm/pat: Avoid truncation when converting cpa->numpages to address
+
+ There are a couple of nasty truncation bugs lurking in the pageattr
+ code that can be triggered when mapping EFI regions, e.g. when we pass
+ a cpa->pgd pointer. Because cpa->numpages is a 32-bit value, shifting
+ left by PAGE_SHIFT will truncate the resultant address to 32-bits.
+
+ Viorel-Cătălin managed to trigger this bug on his Dell machine that
+ provides a ~5GB EFI region which requires 1236992 pages to be mapped.
+ When calling populate_pud() the end of the region gets calculated
+ incorrectly in the following buggy expression,
+
+ end = start + (cpa->numpages << PAGE_SHIFT);
- In drivers/md/md.c get_bitmap_file() uses kmalloc() for creating a
- mdu_bitmap_file_t called "file".
+ And only 188416 pages are mapped. Next, populate_pud() gets invoked
+ for a second time because of the loop in __change_page_attr_set_clr(),
+ only this time no pages get mapped because shifting the remaining
+ number of pages (1048576) by PAGE_SHIFT is zero. At which point the
+ loop in __change_page_attr_set_clr() spins forever because we fail to
+ map progress.
- 5769 file = kmalloc(sizeof(*file), GFP_NOIO);
- 5770 if (!file)
- 5771 return -ENOMEM;
+ Hitting this bug depends very much on the virtual address we pick to
+ map the large region at and how many pages we map on the initial run
+ through the loop. This explains why this issue was only recently hit
+ with the introduction of commit
- This structure is copied to user space at the end of the function.
+ a5caa209ba9c ("x86/efi: Fix boot crash by mapping EFI memmap
+ entries bottom-up at runtime, instead of top-down")
- 5786 if (err == 0 &&
- 5787 copy_to_user(arg, file, sizeof(*file)))
- 5788 err = -EFAULT
+ It's interesting to note that safe uses of cpa->numpages do exist in
+ the pageattr code. If instead of shifting ->numpages we multiply by
+ PAGE_SIZE, no truncation occurs because PAGE_SIZE is a UL value, and
+ so the result is unsigned long.
+
+ To avoid surprises when users try to convert very large cpa->numpages
+ values to addresses, change the data type from 'int' to 'unsigned
+ long', thereby making it suitable for shifting by PAGE_SHIFT without
+ any type casting.
+
+ The alternative would be to make liberal use of casting, but that is
+ far more likely to cause problems in the future when someone adds more
+ code and fails to cast properly; this bug was difficult enough to
+ track down in the first place.

+ x86/mm: Fix types used in pgprot cacheability flags translations
- But if bitmap is disabled only the first byte of "file" is initialized
- with zero, so it's possible to read some bytes (up to 4095) of kernel
- space memory from user space. This is an information leak.
+ For PAE kernels "unsigned long" is not suitable to hold page protection
+ flags, since _PAGE_NX doesn't fit there. This is the reason for quite a
+ few W+X pages getting reported as insecure during boot (observed namely
+ for the entire initrd range).
- 5775 /* bitmap disabled, zero the first byte and copy out */
- 5776 if (!mddev->bitmap_info.file)
- 5777 file->pathname[0] = '\0';

- From: Colin Ian King <colin.king () canonical com>
- Subject: [PATCH] KEYS: ensure we free the assoc array edit if edit is valid
-
- __key_link_end is not freeing the associated array edit structure
- and this leads to a 512 byte memory leak each time an identical
- existing key is added with add_key().
-
- The reason the add_key() system call returns okay is that
- key_create_or_update() calls __key_link_begin() before checking to see
- whether it can update a key directly rather than adding/replacing - which
- it turns out it can. Thus __key_link() is not called through
- __key_instantiate_and_link() and __key_link_end() must cancel the edit.

+ tcp: fix zero cwnd in tcp_cwnd_reduction
+
+ Patch 3759824da87b ("tcp: PRR uses CRB mode by default and SS mode
+ conditionally") introduced a bug that cwnd may become 0 when both
+ inflight and sndcnt are 0 (cwnd = inflight + sndcnt). This may lead
+ to a div-by-zero if the connection starts another cwnd reduction
+ phase by setting tp->prior_cwnd to the current cwnd (0) in
+ tcp_init_cwnd_reduction().
+
+ To prevent this we skip PRR operation when nothing is acked or
+ sacked. Then cwnd must be positive in all cases as long as ssthresh
+ is positive:
+
+ 1) The proportional reduction mode
+ inflight > ssthresh > 0
- This patch is the IPv6 equivalent of commit
- 6c8b4e3ff81b ("arp: flush arp cache on IFF_NOARP change")
+ 2) The reduction bound mode
+ a) inflight == ssthresh > 0
- Without it, we keep buggy neighbours in the cache, with destination
- MAC address equal to our own MAC address.
+ b) inflight < ssthresh
+ sndcnt > 0 since newly_acked_sacked > 0 and inflight < ssthresh
- Tested:
- tcpdump -i eth0 -s 0 ip6 -n -e &
- ip link set dev eth0 arp off
- ping6 remote // sends buggy frames
- ip link set dev eth0 arp on
- ping6 remote // should work once kernel is patched
+ Therefore in all cases inflight and sndcnt can not both be 0.
+ We check invalid tp->prior_cwnd to avoid potential div0 bugs.
+ In reality this bug is triggered only with a sequence of less common
+ events. For example, the connection is terminating an ECN-triggered
+ cwnd reduction with an inflight 0, then it receives reordered/old
+ ACKs or DSACKs from prior transmission (which acks nothing). Or the
+ connection is in fast recovery stage that marks everything lost,
+ but fails to retransmit due to local issues, then receives data
+ packets from other end which acks nothing.

- x86/efi: Use all 64 bit of efi_memmap in setup_e820()
-
- The efi_info structure stores low 32 bits of memory map
- in efi_memmap and high 32 bits in efi_memmap_hi.
+ pptp: fix illegal memory access caused by multiple bind()s
- While constructing pointer in the setup_e820(), need
- to take into account all 64 bit of the pointer.
+ Several times already this has been reported as kasan reports caused by
+ syzkaller and trinity and people always looked at RCU races, but it is
+ much more simple. :)
- It is because on 64bit machine the function
- efi_get_memory_map() may return full 64bit pointer and before
- the patch that pointer was truncated.
+ In case we bind a pptp socket multiple times, we simply add it to
+ the callid_sock list but don't remove the old binding. Thus the old
+ socket stays in the bucket with unused call_id indexes and doesn't get
+ cleaned up. This causes various forms of kasan reports which were hard
+ to pinpoint.
- The issue is triggered on Parallles virtual machine and
- fixed with this patch.
+ Simply don't allow multiple binds and correct error handling in
+ pptp_bind. Also keep sk_state bits in place in pptp_connect.

- efi: Check for NULL efi kernel parameters

- Even though it is documented how to specifiy efi parameters, it is
- possible to cause a kernel panic due to a dereference of a NULL pointer when

-
- This panic is not reproducible with "efi=" as this will result in a non-NULL
- zero-length string.
-
- Thus, verify that the pointer to the parameter string is not NULL. This is
- consistent with other parameter-parsing functions which check for NULL pointers.

+ ipv4+ipv6: Make INET*_ESP select CRYPTO_ECHAINIV
- While we're at it, add comments to help explain what's going on.
+ The ESP algorithms using CBC mode require echainiv. Hence INET*_ESP have
+ to select CRYPTO_ECHAINIV in order to work properly. This solves the
+ issues caused by a misconfiguration as described in [1].
+ The original approach, patching crypto/Kconfig was turned down by
+ Herbert Xu [2].
- This isn't a great long-term fix. This code should probably be
- changed to use something like set_memory_ro.

- x86/mm: Add parenthesis for TLB tracepoint size calculation
+ netfilter: nf_conntrack: use safer way to lock all buckets
- flush_tlb_info->flush_start/end are both normal virtual
- addresses. When calculating 'nr_pages' (only used for the
- tracepoint), I neglected to put parenthesis in.
+ When we need to lock all buckets in the connection hashtable we'd attempt to
+ lock 1024 spinlocks, which is way more preemption levels than supported by
+ the kernel. Furthermore, this behavior was hidden by checking if lockdep is
+ enabled, and if it was - use only 8 buckets(!).
- Thanks to David Koufaty for pointing this out.
+ Fix this by using a global lock and synchronize all buckets on it when we
+ need to lock them all. This is pretty heavyweight, but is only done when we
+ need to resize the hashtable, and that doesn't happen often enough (or at all).

- x86/mm: Remove region_is_ram() call from ioremap
+ pipe: limit the per-user amount of pages allocated in pipes
+
+ On no-so-small systems, it is possible for a single process to cause an
+ OOM condition by filling large pipes with data that are never read. A
+ typical process filling 4000 pipes with 1 MB of data will use 4 GB of
+ memory. On small systems it may be tricky to set the pipe max size to
+ prevent this from happening.
+
+ This patch makes it possible to enforce a per-user soft limit above
+ which new pipes will be limited to a single page, effectively limiting
+ them to 4 kB each, as well as a hard limit above which no new pipes may
+ be created for this user. This has the effect of protecting the system
+ against memory abuse without hurting other users, and still allowing
+ pipes to work correctly though with less data at once.
- __ioremap_caller() calls region_is_ram() to walk through the
- iomem_resource table to check if a target range is in RAM, which was
- added to improve the lookup performance over page_is_ram() (commit
- 906e36c5c717 "x86: use optimized ioresource lookup in ioremap
- function"). page_is_ram() was no longer used when this change was
- added, though.
+ The limit are controlled by two new sysctls : pipe-user-pages-soft, and
+ pipe-user-pages-hard. Both may be disabled by setting them to zero. The
+ default soft limit allows the default number of FDs per process (1024)
+ to create pipes of the default size (64kB), thus reaching a limit of 64MB
+ before starting to create only smaller pipes. With 256 processes limited
+ to 1024 FDs each, this results in 1024*64kB + (256*1024 - 1024) * 4kB =
+ 1084 MB of memory allocated for a user. The hard limit is disabled by
+ default to avoid breaking existing applications that make intensive use
+ of pipes (eg: for splicing).
- __ioremap_caller() then calls walk_system_ram_range(), which had
- replaced page_is_ram() to improve the lookup performance (commit
- c81c8a1eeede "x86, ioremap: Speed up check for RAM pages").

+
+ compat_ioctl: don't call do_ioctl under set_fs(KERNEL_DS)
- Since both checks walk through the same iomem_resource table for
- the same purpose, there is no need to call both functions.
+ This replaces all code in fs/compat_ioctl.c that translated
+ ioctl arguments into a in-kernel structure, then performed
+ do_ioctl under set_fs(KERNEL_DS), with code that allocates
+ data on the user stack and can call the VFS ioctl handler
+ under USER_DS.
- Aside of that walk_system_ram_range() is the only useful check at the
- moment because region_is_ram() always returns -1 due to an
- implementation bug. That bug in region_is_ram() cannot be fixed
- without breaking existing ioremap callers, which rely on the subtle
- difference of walk_system_ram_range() versus non page aligned ranges.
+ This is done as a hardening measure because the caller
+ does not know what kind of ioctl handler will be invoked,
+ only that no corresponding compat_ioctl handler exists and
+ what the ioctl command number is. The accidental
+ invocation of an unlocked_ioctl handler that unexpectedly
+ calls copy_to_user could be a severe security issue.

- Once these offending callers are fixed we can use region_is_ram() and
- remove walk_system_ram_range().

- x86/mm: Move warning from __ioremap_check_ram() to the call site
+ compat_ioctl: don't look up the fd twice
- __ioremap_check_ram() has a WARN_ONCE() which is emitted when the
- given pfn range is not RAM. The warning is bogus in two aspects:
+ In code in fs/compat_ioctl.c that translates ioctl arguments
+ into a in-kernel structure, then performs sys_ioctl, possibly
+ under set_fs(KERNEL_DS), this commit changes the sys_ioctl
+ calls to do_ioctl calls. do_ioctl is a new function that does
+ the same thing as sys_ioctl, but doesn't look up the fd again.
- - it never triggers since walk_system_ram_range() only calls
- __ioremap_check_ram() for RAM ranges.
+ This change is made to avoid (potential) security issues
+ because of ioctl handlers that accept one of the ioctl
+ commands I2C_FUNCS, VIDEO_GET_EVENT, MTIOCPOS, MTIOCGET,
+ TIOCGSERIAL, TIOCSSERIAL, RTC_IRQP_READ, RTC_EPOCH_READ.
+ This can happen for multiple reasons:
- - the warning message is wrong as it says: "ioremap on RAM' after it
- established that the pfn range is not RAM.
+ - The ioctl command number could be reused.
+ - The ioctl handler might not check the full ioctl
+ command. This is e.g. true for drm_ioctl.
+ - The ioctl handler is very special, e.g. cuse_file_ioctl
- Move the WARN_ONCE() to __ioremap_caller(), and update the message to
- include the address range so we get an actual warning when something
- tries to ioremap system RAM.
+ The real issue is that set_fs(KERNEL_DS) is used here,
+ but that's fixed in a separate commit
+ "compat_ioctl: don't call do_ioctl under set_fs(KERNEL_DS)".
- [ tglx: Massaged changelog ]
+ This change mitigates potential security issues by
+ preventing a race that permits invocation of
+ unlocked_ioctl handlers under KERNEL_DS through compat
+ code even if a corresponding compat_ioctl handler exists.

- mm: Fix bugs in region_is_ram()
+ include/linux/poison.h: use POISON_POINTER_DELTA for poison pointers
- region_is_ram() looks up the iomem_resource table to check if
- a target range is in RAM. However, it always returns with -1
- due to invalid range checks. It always breaks the loop at the
- first entry of the table.
+ TIMER_ENTRY_STATIC is defined as a poison pointers which
+ should point to nowhere. Redefine them using POISON_POINTER_DELTA
+ arithmetics to make sure they really point to non-mappable area declared
+ by the target architecture.
- Another issue is that it compares p->flags and flags, but it always
- fails. flags is declared as int, which makes it as a negative value
- with IORESOURCE_BUSY (0x80000000) set while p->flags is unsigned long.

+ ALSA: hrtimer: Fix stall by hrtimer_cancel()
- chrdev_open() increases reference counter on cdev->owner. Instead of
- assigning the owner to mei subsystem, the owner has to be set to the
- underlaying HW module (mei_me or mei_txe), so once the device is opened
- the HW module cannot be unloaded.
+ hrtimer_cancel() waits for the completion from the callback, thus it
+ must not be called inside the callback itself. This was already a
+ problem in the past with ALSA hrtimer driver, and the early commit
+ [fcfdebe70759: ALSA: hrtimer - Fix lock-up] tried to address it.

+ However, the previous fix is still insufficient: it may still cause a
+ lockup when the ALSA timer instance reprograms itself in its callback.
+ Then it invokes the start function even in snd_timer_interrupt() that
+ is called in hrtimer callback itself, results in a CPU stall. This is
+ no hypothetical problem but actually triggered by syzkaller fuzzer.
+
+ This patch tries to fix the issue again. Now we call
+ hrtimer_try_to_cancel() at both start and stop functions so that it
+ won't fall into a deadlock, yet giving some chance to cancel the queue
+ if the functions have been called outside the callback. The proper
+ hrtimer_cancel() is called in anyway at closing, so this should be
+ enough.

- inet: frags: remove INET_FRAG_EVICTED and use list_evictor for the test
+ ALSA: timer: Harden slave timer list handling
- We can simply remove the INET_FRAG_EVICTED flag to avoid all the flags
- race conditions with the evictor and use a participation test for the
- evictor list, when we're at that point (after inet_frag_kill) in the
- timer there're 2 possible cases:
+ A slave timer instance might be still accessible in a racy way while
+ operating the master instance as it lacks of locking. Since the
+ master operation is mostly protected with timer->lock, we should cope
+ with it while changing the slave instance, too. Also, some linked
+ lists (active_list and ack_list) of slave instances aren't unlinked
+ immediately at stopping or closing, and this may lead to unexpected
+ accesses.
- 1. The evictor added the entry to its evictor list while the timer was
- waiting for the chainlock
- or
- 2. The timer unchained the entry and the evictor won't see it
+ This patch tries to address these issues. It adds spin lock of
+ timer->lock (either from master or slave, which is equivalent) in a
+ few places. For avoiding a deadlock, we ensure that the global
+ slave_active_lock is always locked at first before each timer lock.
- In both cases we should be able to see list_evictor correctly due
- to the sync on the chainlock.
+ Also, ack and active_list of slave instances are properly unlinked at
+ snd_timer_stop() and snd_timer_close().
- Joint work with Florian Westphal.
+ Last but not least, remove the superfluous call of _snd_timer_stop()
+ at removing slave links. This is a noop, and calling it may confuse
+ readers wrt locking. Further cleanup will follow in a later patch.

- inet: frag: don't wait for timer deletion when evicting
+ ALSA: timer: Fix race among timer ioctls
- Frank reports 'NMI watchdog: BUG: soft lockup' errors when
- load is high. Instead of (potentially) unbounded restarts of the
- eviction process, just skip to the next entry.
+ ALSA timer ioctls have an open race and this may lead to a
+ use-after-free of timer instance object. A simplistic fix is to make
+ each ioctl exclusive. We have already tread_sem for controlling the
+ tread, and extend this as a global mutex to be applied to each ioctl.
- One caveat is that, when a netns is exiting, a timer may still be running
- by the time inet_evict_bucket returns.
+ The downside is, of course, the worse concurrency. But these ioctls
+ aren't to be parallel accessible, in anyway, so it should be fine to
+ serialize there.
- We use the frag memory accounting to wait for outstanding timers,
- so that when we free the percpu counter we can be sure no running
- timer will trip over it.

- inet: frag: change *_frag_mem_limit functions to take netns_frags as argument

- Followup patch will call it after inet_frag_queue was freed, so q->net
- doesn't work anymore (but netf = q->net; free(q); mem_limit(netf) would).
+ ALSA timer instance object has a couple of linked lists and they are
+ unlinked unconditionally at snd_timer_stop(). Meanwhile
+ snd_timer_interrupt() unlinks it, but it calls list_del() which leaves
+ the element list itself unchanged. This ends up with unlinking twice,

- inet: frag: don't re-use chainlist for evictor
-
- commit 65ba1f1ec0eff ("inet: frags: fix a race between inet_evict_bucket
- and inet_frag_kill") describes the bug, but the fix doesn't work reliably.
+ ovs: limit ovs recursions in ovs_execute_actions to not corrupt stack
- Problem is that ->flags member can be set on other cpu without chainlock
- being held by that task, i.e. the RMW-Cycle can clear INET_FRAG_EVICTED
- bit after we put the element on the evictor private list.
+ It was seen that defective configurations of openvswitch could overwrite
+ the STACK_END_MAGIC and cause a hard crash of the kernel because of too
+ many recursions within ovs.
- We can crash when walking the 'private' evictor list since an element can
- be deleted from list underneath the evictor.
+ This problem arises due to the high stack usage of openvswitch. The rest
+ of the kernel is fine with the current limit of 10 (RECURSION_LIMIT).
- Join work with Nikolay Alexandrov.
+ We use the already existing recursion counter in ovs_execute_actions to
+ implement an upper bound of 5 recursions.

- iommu/vt-d: Fix VM domain ID leak
-
- This continues the attempt to fix commit fb170fb4c548 ("iommu/vt-d:
- Introduce helper functions to make code symmetric for readability").
- The previous attempt in commit 71684406905f ("iommu/vt-d: Detach
- domain *only* from attached iommus") overlooked the fact that
- dmar_domain.iommu_bmp gets cleared for VM domains when devices are
- detached:
-
- intel_iommu_detach_device
- domain_remove_one_dev_info
- domain_detach_iommu
-
- The domain is detached from the iommu, but the iommu is still attached
- to the domain, for whatever reason. Thus when we get to domain_exit(),
- we can't rely on iommu_bmp for VM domains to find the active iommus,
- we must check them all. Without that, the corresponding bit in
- intel_iommu.domain_ids doesn't get cleared and repeated VM domain
- creation and destruction will run out of domain IDs. Meanwhile we
- still can't call iommu_detach_domain() on arbitrary non-VM domains or
- we risk clearing in-use domain IDs, as 71684406905f attempted to
- address.
-
- It's tempting to modify iommu_detach_domain() to test the domain
- iommu_bmp, but the call ordering from domain_remove_one_dev_info()
- prevents it being able to work as fb170fb4c548 seems to have intended.
- Caching of unused VM domains on the iommu object seems to be the root
- of the problem, but this code is far too fragile for that kind of
- rework to be proposed for stable, so we simply revert this chunk to
- its state prior to fb170fb4c548.

- Correct the handling of unmounted mounts in detach_mount. When the

- mnt: Clarify and correct the disconnect logic in umount_tree
+ proc: add a reschedule point in proc_readfd_common()
- rmdir mntpoint will result in an infinite loop when there is
- a mount locked on the mountpoint in another mount namespace.
+ User can pass an arbitrary large buffer to getdents().
- This is because the logic to test to see if a mount should
- be disconnected in umount_tree is buggy.
+ It is typically a 32KB buffer used by libc scandir() implementation.
- Move the logic to decide if a mount should remain connected to
- it's mountpoint into it's own function disconnect_mount so that
- clarity of expression instead of terseness of expression becomes
- a virtue.
+ When scanning /proc/{pid}/fd, we can hold cpu way too long,
+ so add a cond_resched() to be kind with other tasks.
- When the conditions where it is invalid to leave a mount connected
- are first ruled out, the logic for deciding if a mount should
- be disconnected becomes much clearer and simpler.
+ We've seen latencies of more than 50ms on real workloads.

- ARM: net: fix condition for load_order > 0 when translating load instructions.
+ net: bpf: reject invalid shifts
- To check whether the load should take the fast path or not, the code
- would check that (r_skb_hlen - load_order) is greater than the offset
- of the access using an "Unsigned higher or same" condition. For
- halfword accesses and an skb length of 1 at offset 0, that test is
- valid, as we end up comparing 0xffffffff(-1) and 0, so the fast path
- is taken and the filter allows the load to wrongly succeed. A similar
- issue exists for word loads at offset 0 and an skb length of less than
- 4.
+ On ARM64, a BUG() is triggered in the eBPF JIT if a filter with a
+ constant shift that can't be encoded in the immediate field of the
+ UBFM/SBFM instructions is passed to the JIT. Since these shifts
+ amounts, which are negative or >= regsize, are invalid, reject them in
+ the eBPF verifier and the classic BPF filter checker, for all
+ architectures.
- Fix that by using the condition "Signed greater than or equal"
- condition for the fast path code for load orders greater than 0.

- net: mvneta: fix refilling for Rx DMA buffers
+ unix: properly account for FDs passed over unix sockets
- With the actual code, if a memory allocation error happens while
- refilling a Rx descriptor, then the original Rx buffer is both passed
- to the networking stack (in a SKB) and let in the Rx ring. This leads
- to various kernel oops and crashes.
+ It is possible for a process to allocate and accumulate far more FDs than
+ the process' limit by sending them over a unix socket then closing them
+ to keep the process' fd count low.
- As a fix, this patch moves Rx descriptor refilling ahead of building
- SKB with the associated Rx buffer. In case of a memory allocation
- failure, data is dropped and the original DMA buffer is put back into
- the Rx ring.
+ This change addresses this problem by keeping track of the number of FDs
+ in flight per user and preventing non-privileged processes from having
+ more FDs in flight than their configured FD limit.

- sched: cls_bpf: fix panic on filter replace
+ net: sctp: prevent writes to cookie_hmac_alg from accessing invalid memory
- The following test case causes a NULL pointer dereference in cls_bpf:
+ proc_dostring() needs an initialized destination string, while the one
+ provided in proc_sctp_do_hmac_alg() contains stack garbage.
- FOO="1,6 0 0 4294967295,"
- tc filter add dev foo parent 1: bpf bytecode "$FOO" flowid 1:1 action ok
- tc filter replace dev foo parent 1: pref 49152 handle 0x1 \
- bpf bytecode "$FOO" flowid 1:1 action drop
+ Thus, writing to cookie_hmac_alg would strlen() that garbage and end up
+ accessing invalid memory.
- The problem is that commit 1f947bf151e9 ("net: sched: rcu'ify cls_bpf")
- accidentally swapped the arguments of list_replace_rcu(), the old
- element needs to be the first argument and the new element the second.

- sched: cls_flow: fix panic on filter replace
-
- The following test case causes a NULL pointer dereference in cls_flow:
-
- tc filter add dev foo parent 1: handle 0x1 flow hash keys dst action ok
- tc filter replace dev foo parent 1: pref 49152 handle 0x1 \
- flow hash keys mark action drop
-
- To be more precise, actually two different panics are fixed, the first
- occurs because tcf_exts_init() is not called on the newly allocated
- filter when we do a replace. And the second panic uncovered after that
- happens since the arguments of list_replace_rcu() are swapped, the old
- element needs to be the first argument and the new element the second.
-
- Fixes: 70da9f0bf999 ("net: sched: cls_flow use RCU")

- parisc: mm: Fix a memory leak related to pmd not attached to the pgd
+ RDS: fix race condition when sending a message on unbound socket
- Commit 0e0da48dee8d ("parisc: mm: don't count preallocated pmds")
- introduced a memory leak.
+ commit 8c7188b23474cca017b3ef354c4a58456f68303a upstream.
- After this commit, the 'return' statement in pmd_free is executed in all
- cases. Even for pmd that are not attached to the pgd. So 'free_pages'
- can never be called anymore, leading to a memory leak.
+ Sasha's found a NULL pointer dereference in the RDS connection code when
+ sending a message to an apparently unbound socket. The problem is caused
+ by the code checking if the socket is bound in rds_sendmsg(), which checks
+ the rs_bound_addr field without taking a lock on the socket. This opens a
+ race where rs_bound_addr is temporarily set but where the transport is not
+ in rds_bind(), leading to a NULL pointer dereference when trying to
+ dereference 'trans' in __rds_conn_create().

-
- Analysis reveals the cause of the crash to be due to STp->device
- being NULL. The pointer was NULLed via scsi_tape_put(STp) when it
- calls scsi_tape_release(). In st_open() we jump to err_out after
- scsi_block_when_processing_errors() completes and returns the
- device as offline (sdev_state was SDEV_DEL):
-
- 1180 /* Open the device. Needs to take the BKL only because of incrementing the SCSI host
- 1181 module count. */
- 1182 static int st_open(struct inode *inode, struct file *filp)
- 1183 {
- 1184 int i, retval = (-EIO);
- 1185 int resumed = 0;
- 1186 struct scsi_tape *STp;
- 1187 struct st_partstat *STps;
- 1188 int dev = TAPE_NR(inode);
- 1189 char *name;
- ...
- 1217 if (scsi_autopm_get_device(STp->device) < 0) {
- 1218 retval = -EIO;
- 1219 goto err_out;
- 1220 }
- 1221 resumed = 1;
- 1222 if (!scsi_block_when_processing_errors(STp->device)) {
- 1223 retval = (-ENXIO);
- 1224 goto err_out;
- 1225 }
- ...
- 1264 err_out:
- 1265 normalize_buffer(STp->buffer);
- 1266 spin_lock(&st_use_lock);
- 1267 STp->in_use = 0;
- 1268 spin_unlock(&st_use_lock);
- 1269 scsi_tape_put(STp); <-- STp->device = 0 after this
- 1270 if (resumed)
- 1271 scsi_autopm_put_device(STp->device);
- 1272 return retval;
-
- The ref count for the struct scsi_tape had already been reduced
- to 1 when the .remove method of the st module had been called.
- The kref_put() in scsi_tape_put() caused scsi_tape_release()
- to be called:
-
- 0266 static void scsi_tape_put(struct scsi_tape *STp)
- 0267 {
- 0268 struct scsi_device *sdev = STp->device;
- 0269
- 0270 mutex_lock(&st_ref_mutex);
- 0271 kref_put(&STp->kref, scsi_tape_release); <-- calls this
- 0272 scsi_device_put(sdev);
- 0273 mutex_unlock(&st_ref_mutex);
- 0274 }
-
- In scsi_tape_release() the struct scsi_device in the struct
- scsi_tape gets set to NULL:
-
- 4273 static void scsi_tape_release(struct kref *kref)
- 4274 {
- 4275 struct scsi_tape *tpnt = to_scsi_tape(kref);
- 4276 struct gendisk *disk = tpnt->disk;
- 4277
- 4278 tpnt->device = NULL; <<<---- where the dev is nulled
- 4279
- 4280 if (tpnt->buffer) {
- 4281 normalize_buffer(tpnt->buffer);
- 4282 kfree(tpnt->buffer->reserved_pages);
- 4283 kfree(tpnt->buffer);
- 4284 }
- 4285
- 4286 disk->private_data = NULL;
- 4287 put_disk(disk);
- 4288 kfree(tpnt);
- 4289 return;
- 4290 }
-
- Although the problem was reported on SLES11.3 the problem appears
- in linux-next as well.
-
- The crash is fixed by reordering the code so we no longer access
- the struct scsi_tape after the kref_put() is done on it in st_open().

-
- include, lib: add __printf attributes to several function prototypes
-
- Using __printf attributes helps to detect several format string issues
- at compile time (even though -Wformat-security is currently disabled in
- Makefile). For example it can detect when formatting a pointer as a
- number, like the issue fixed in commit a3fa71c40f18 ("wl18xx: show
- rx_frames_per_rates as an array as it really is"), or when the arguments
- do not match the format string, c.f. for example commit 5ce1aca81435
- ("reiserfs: fix __RASSERT format string").
-
- To prevent similar bugs in the future, add a __printf attribute to every
- function prototype which needs one in include/linux/ and lib/. These
- functions were mostly found by using gcc's -Wsuggest-attribute=format
- flag.

- mm/page_owner: fix possible access violation
-
- When I tested my new patches, I found that page pointer which is used
- for setting page_owner information is changed. This is because page
- pointer is used to set new migratetype in loop. After this work, page
- pointer could be out of bound. If this wrong pointer is used for
- page_owner, access violation happens. Below is error message that I
- got.

- mm/cma_debug: fix debugging alloc/free interface
+ RDS: verify the underlying transport exists before creating a connection
- CMA has alloc/free interface for debugging. It is intended that
- alloc/free occurs in specific CMA region, but, currently, alloc/free
- interface is on root dir due to the bug so we can't select CMA region
- where alloc/free happens.
+ There was no verification that an underlying transport exists when creating
+ a connection, this would cause dereferencing a NULL ptr.
- This patch fixes this problem by making alloc/free interface per CMA
- region.
+ It might happen on sockets that weren't properly bound before attempting to
+ send a message, which will cause a NULL ptr deref:

- mm/cma_debug: correct size input to bitmap function
+ ftrace/module: Call clean up function when module init fails early
- In CMA, 1 bit in bitmap means 1 << order_per_bits pages so size of
- bitmap is cma->count >> order_per_bits rather than just cma->count.
- This patch fixes it.
+ If the module init code fails after calling ftrace_module_init() and before
+ calling do_init_module(), we can suffer from a memory leak. This is because
+ ftrace_module_init() allocates pages to store the locations that ftrace
+ hooks are placed in the module text. If do_init_module() fails, it still
+ calls the MODULE_GOING notifiers which will tell ftrace to do a clean up of
+ the pages it allocated for the module. But if load_module() fails before
+ then, the pages allocated by ftrace_module_init() will never be freed.

- fq_codel: fix return value of fq_codel_drop()
+ 6pack: fix free memory scribbles
- The ->drop() is supposed to return the number of bytes it dropped,
- however fq_codel_drop() returns the index of the flow where it drops
- a packet from.
+ commit acf673a3187edf72068ee2f92f4dc47d66baed47 fixed a user triggerable free
+ memory scribble but in doing so replaced it with a different one that allows
+ the user to control the data and scribble even more.
- Fix this by introducing a helper to wrap fq_codel_drop().
+ sixpack_close is called by the tty layer in tty context. The tty context is
+ protected by sp_get() and sp_put(). However network layer activity via
+ sp_xmit() is not protected this way. We must therefore stop the queue
+ otherwise the user gets to dump a buffer mostly of their choice into freed
+ kernel pages.

- rtnetlink: reject non-IFLA_VF_PORT attributes inside IFLA_VF_PORTS
+ net: sched: fix missing free per cpu on qstats
- Similarly as in commit 4f7d2cdfdde7 ("rtnetlink: verify IFLA_VF_INFO
- attributes before passing them to driver"), we have a double nesting
- of netlink attributes, i.e. IFLA_VF_PORTS only contains IFLA_VF_PORT
- that is nested itself. While IFLA_VF_PORTS is a verified attribute
- from ifla_policy[], we only check if the IFLA_VF_PORTS container has
- IFLA_VF_PORT attributes and then pass the attribute's content itself
- via nla_parse_nested(). It would be more correct to reject inner types
- other than IFLA_VF_PORT instead of continuing parsing and also similarly
- as in commit 4f7d2cdfdde7, to check for a minimum of NLA_HDRLEN.
+ When a qdisc is using per cpu stats (currently just the ingress
+ qdisc) only the bstats are being freed. This also free's the qstats.

- net: Clone skb before setting peeked flag
+ ARM: net: bpf: fix zero right shift
- Shared skbs must not be modified and this is crucial for broadcast
- and/or multicast paths where we use it as an optimisation to avoid
- unnecessary cloning.
+ The LSR instruction cannot be used to perform a zero right shift since a
+ 0 as the immediate value (imm5) in the LSR instruction encoding means
+ that a shift of 32 is perfomed. See DecodeIMMShift() in the ARM ARM.
- The function skb_recv_datagram breaks this rule by setting peeked
- without cloning the skb first. This causes funky races which leads
- to double-free.
+ Make the JIT skip generation of the LSR if a zero-shift is requested.
- This patch fixes this by cloning the skb and replacing the skb
- in the list when setting skb->peeked.

- net: Fix skb csum races when peeking
+ bridge: Only call /sbin/bridge-stp for the initial network namespace
- When we calculate the checksum on the recv path, we store the
- result in the skb as an optimisation in case we need the checksum
- again down the line.
+ [I stole this patch from Eric Biederman. He wrote:]
- This is in fact bogus for the MSG_PEEK case as this is done without
- any locking. So multiple threads can peek and then store the result
- to the same skb, potentially resulting in bogus skb states.
+ > There is no defined mechanism to pass network namespace information

- This patch fixes this by only storing the result if the skb is not
- shared. This preserves the optimisations for the few cases where
- it can be done safely due to locking or other reasons, e.g., SIOCINQ.

- vmxnet3: prevent receive getting out of sequence on napi poll
-
- vmxnet3's current napi path is built to count every rx descriptor we recieve,
- and use that as a count of the napi budget. That means its possible to return
- from a napi poll halfway through recieving a fragmented packet accross multiple
- dma descriptors. If that happens, the next napi poll will start with the
- descriptor ring in an improper state (e.g. the first descriptor we look at may
- have the end-of-packet bit set), which will cause a BUG halt in the driver.
+ connector: bump skb->users before callback invocation
- Fix the issue by only counting whole received packets in the napi poll and
- returning that value, rather than the descriptor count.
+ Dmitry reports memleak with syskaller program.
+ Problem is that connector bumps skb usecount but might not invoke callback.
- Tested by the reporter and myself, successfully
+ So move skb_get to where we invoke the callback.

- freeing unlinked file indefinitely delayed
-
- Normally opening a file, unlinking it and then closing will have
- the inode freed upon close() (provided that it's not otherwise busy and
- has no remaining links, of course). However, there's one case where that
- does *not* happen. Namely, if you open it by fhandle with cold dcache,
- then unlink() and close().
-
- In normal case you get d_delete() in unlink(2) notice that dentry
- is busy and unhash it; on the final dput() it will be forcibly evicted from
- dcache, triggering iput() and inode removal. In this case, though, we end
- up with *two* dentries - disconnected (created by open-by-fhandle) and
- regular one (used by unlink()). The latter will have its reference to inode
- dropped just fine, but the former will not - it's considered hashed (it
- is on the ->s_anon list), so it will stay around until the memory pressure
- will finally do it in. As the result, we have the final iput() delayed
- indefinitely. It's trivial to reproduce -
-
- void flush_dcache(void)
- {
- system("mount -o remount,rw /");
- }
-
- static char buf[20 * 1024 * 1024];
-
- main()
- {
- int fd;
- union {
- struct file_handle f;
- char buf[MAX_HANDLE_SZ];
- } x;
- int m;
-
- x.f.handle_bytes = sizeof(x);
- chdir("/root");
- mkdir("foo", 0700);
- fd = open("foo/bar", O_CREAT | O_RDWR, 0600);
- close(fd);
- name_to_handle_at(AT_FDCWD, "foo/bar", &x.f, &m, 0);
- flush_dcache();
- fd = open_by_handle_at(AT_FDCWD, &x.f, O_RDWR);
- unlink("foo/bar");
- write(fd, buf, sizeof(buf));
- system("df ."); /* 20Mb eaten */
- close(fd);
- system("df ."); /* should've freed those 20Mb */
- flush_dcache();
- system("df ."); /* should be the same as #2 */
- }
-

- cred_subscribers has to do with the ->cred and ->real_cred fields, not our
- delayed_cred field, so don't count it towards it to avoid a BUG() with
- DEBUG_CREDENTIALS enabled
+ It was noticed during an internal audit that the code under GRKERNSEC_PROC_MEMMAP
+ which aimed to enforce a 16MB minimum on RLIMIT_DATA for suid/sgid binaries only
+ did so if RLIMIT_DATA was set lower than PAGE_SIZE.
+
+ This addition was only supplemental as GRKERNSEC_BRUTE is the main defense
+ against suid/sgid attacks and the flaw above would only eliminate the extra
+ entropy provided for the brk-managed heap, still leaving it with the minimum
+ of 16-bit entropy for mmap on x86 and 28 on x64.

- fix label typo in PCID alternatives, from pipacs
+ There's a race between keyctl_read() and keyctl_revoke(). If the revoke
+ happens between keyctl_read() checking the validity of a key and the key's
+ semaphore being taken, then the key type read method will see a revoked key.
+
+ This causes a problem for the user-defined key type because it assumes in
+ its read method that there will always be a payload in a non-revoked key
+ and doesn't check for a NULL pointer.
+
+ Fix this by making keyctl_read() check the validity of a key after taking
+ semaphore instead of before.
+
+ I think the bug was introduced with the original keyrings code.
+
+ This was discovered by a multithreaded test program generated by syzkaller
+ (http://github.com/google/syzkaller). Here's a cleaned up version:
+
+ #include <sys/types.h>
+ #include <keyutils.h>
+ #include <pthread.h>
+ void *thr0(void *arg)
+ {
+ key_serial_t key = (unsigned long)arg;
+ keyctl_revoke(key);
+ return 0;
+ }
+ void *thr1(void *arg)
+ {
+ key_serial_t key = (unsigned long)arg;
+ char buffer[16];
+ keyctl_read(key, buffer, 16);
+ return 0;
+ }
+ int main()
+ {
+ key_serial_t key = add_key("user", "%", "foo", 3, KEY_SPEC_USER_KEYRING);
+ pthread_t th[5];
+ pthread_create(&th[0], 0, thr0, (void *)(unsigned long)key);
+ pthread_create(&th[1], 0, thr1, (void *)(unsigned long)key);
+ pthread_create(&th[2], 0, thr0, (void *)(unsigned long)key);
+ pthread_create(&th[3], 0, thr1, (void *)(unsigned long)key);
+ pthread_join(th[0], 0);
+ pthread_join(th[1], 0);
+ pthread_join(th[2], 0);
+ pthread_join(th[3], 0);
+ return 0;
+ }
+
+ Build as:
+
+ cc -o keyctl-race keyctl-race.c -lkeyutils -lpthread
+
+ Run as:
+
+ while keyctl-race; do :; done
+
+ as it may need several iterations to crash the kernel. The crash can be
+ summarised as:
+
+ BUG: unable to handle kernel NULL pointer dereference at 0000000000000010
+ IP: [<ffffffff81279b08>] user_read+0x56/0xa3

- constify compile fix on dsa_netdevice_nb
+ ptrace_has_cap() checks whether the current process should be
+ treated as having a certain capability for ptrace checks
+ against another process. Until now, this was equivalent to
+ has_ns_capability(current, target_ns, CAP_SYS_PTRACE).
+
+ However, if a root-owned process wants to enter a user
+ namespace for some reason without knowing who owns it and
+ therefore can't change to the namespace owner's uid and gid
+ before entering, as soon as it has entered the namespace,
+ the namespace owner can attach to it via ptrace and thereby
+ gain access to its uid and gid.
+
+ While it is possible for the entering process to switch to
+ the uid of a claimed namespace owner before entering,
+ causing the attempt to enter to fail if the claimed uid is
+ wrong, this doesn't solve the problem of determining an
+ appropriate gid.
+
+ With this change, the entering process can first enter the
+ namespace and then safely inspect the namespace's
+ properties, e.g. through /proc/self/{uid_map,gid_map},
+ assuming that the namespace owner doesn't have access to
+ uid 0.

- compile fix and fix tracefs const modification
+ ipv6: automatically enable stable privacy mode if stable_secret set
+
+ Bjørn reported that while we switch all interfaces to privacy stable mode
+ when setting the secret, we don't set this mode for new interfaces. This
+ does not make sense, so change this behaviour.
+
+ Fixes: 622c81d57b392cc ("ipv6: generation of stable privacy addresses for link-local and autoconf")

+ - Emese fixed an intentional overflow caused by gcc, reported by saironiq (https://forums.grsecurity.net/viewtopic.php?f=3&t=4333)

+ - Emese fixed the initify plugin to detect some captured use of __func__, reported by Rasmus Villemoes <linux@rasmusvillemoes.dk>
+ - constrained shmmax and shmall to avoid triggering size overflow checks, reported by Mathias Krause <minipli@ld-linux.so>
+ - the checker plugin can partially handle sparse's locking context annotations, it's context insensitive and thus not exactly useful for now, also see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59856
