- Subject: [PATCH net] packet: fix heap info leak in PACKET_DIAG_MCLIST sock_diag
- interface
-
- Because we miss to wipe the remainder of i->addr[] in packet_mc_add(),
- pdiag_put_mclist() leaks uninitialized heap bytes via the
- PACKET_DIAG_MCLIST netlink attribute.
-
- Fix this by explicitly memset(0)ing the remaining bytes in i->addr[].

- Fixes: eea68e2f1a00 ("packet: Report socket mclist info via diag module")

- ---
- The bug itself precedes commit eea68e2f1a00 but the list wasn't exposed
- to userland before the introduction of the packet_diag interface.
- Therefore the "Fixes:" line on that commit.

- 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));
-
- Prevents a splat due to skb_under_panic:
-
- skbuff: skb_under_panic: text:ffffffff8143397b len:2126 put:14 \

- When creating an ip6tnl tunnel with ip tunnel, rtnl_link_ops is not set
- before ip6_tnl_create2 is called. When register_netdevice is called, there
- is no linkinfo attribute in the NEWLINK message because of that.

- USB: iowarrior: fix oops with malicious USB descriptors
+ In the ASN.1 decoder, when the length field of an ASN.1 value is extracted,

+ to the cursor. With a sufficiently large size indicated, the check:
- The iowarrior driver expects at least one valid endpoint. If given
- malicious descriptors that specify 0 for the number of endpoints,
- it will crash in the probe function. Ensure there is at least
- one endpoint on the interface before using it.

+ Fix this by checking the length indicated against the amount of remaining
+ data in both places a definite length is determined.
+
+ Whilst we're at it, make the following changes:
+
+ (1) Check the maximum size of extended length does not exceed the capacity
+ of the variable it's being stored in (len) rather than the type that
+ variable is assumed to be (size_t).
+
+ (2) Compare the EOC tag to the symbolic constant ASN1_EOC rather than the
+ integer 0.
+
+ (3) To reduce confusion, move the initialisation of len outside of:
+
+ for (len = 0; n > 0; n--) {
+
+ since it doesn't have anything to do with the loop counter n.

- KVM: fix spin_lock_init order on x86

- Moving the initialization earlier is needed in 4.6 because
- kvm_arch_init_vm is now using mmu_lock, causing lockdep to
- complain:
-
- [ 284.440294] INFO: trying to register non-static key.
- [ 284.445259] the code is fine but needs lockdep annotation.

-
- 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
- and leaves del_timer_sync() at the close instead. This is because of
- the restriction by the design of ALSA timer: namely, the stop callback
- may be called from the timer handler, and calling the sync shall lead
- to a hangup. However, this also triggers a kernel BUG() when the
- timer is rearmed immediately after stopping without sync:
- kernel BUG at kernel/time/timer.c:966!
- Call Trace:
- <IRQ>
- [<ffffffff8239c94e>] snd_timer_s_start+0x13e/0x1a0
- [<ffffffff8239e1f4>] snd_timer_interrupt+0x504/0xec0
- [<ffffffff8122fca0>] ? debug_check_no_locks_freed+0x290/0x290
- [<ffffffff8239ec64>] snd_timer_s_function+0xb4/0x120
- [<ffffffff81296b72>] call_timer_fn+0x162/0x520
- [<ffffffff81296add>] ? call_timer_fn+0xcd/0x520
- [<ffffffff8239ebb0>] ? snd_timer_interrupt+0xec0/0xec0
- ....
-
- It's the place where add_timer() checks the pending timer. It's clear
- that this may happen after the immediate restart without sync in our
- cases.
-
- So, the workaround here is just to use mod_timer() instead of
- add_timer(). This looks like a band-aid fix, but it's a right move,
- as snd_timer_interrupt() takes care of the continuous rearm of timer.

- 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
- cache.

- 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.

- ext4: move unlocked dio protection from ext4_alloc_file_blocks()
-
- Currently ext4_alloc_file_blocks() was handling protection against
- unlocked DIO. However we now need to sometimes call it under i_mmap_sem
- and sometimes not and DIO protection ranks above it (although strictly
- speaking this cannot currently create any deadlocks). Also
- ext4_zero_range() was actually getting & releasing unlocked DIO
- protection twice in some cases. Luckily it didn't introduce any real bug
- but it was a land mine waiting to be stepped on. So move DIO protection
- out from ext4_alloc_file_blocks() into the two callsites.

- 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

- the driver is instantiated before accessing its data structures.

- 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():
-
- UBSAN: Undefined behaviour in crypto/asymmetric_keys/pkcs7_trust.c:194:14
- load of value 82 is not a valid value for type '_Bool'
- [...]
- Call Trace:

-
- The implication is that pkcs7_validate_trust() effectively grants trust
- when it really shouldn't have.
-
- Fix this by explicitly setting *_trusted to false at the very beginning
- of 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'
- CPU: 3 PID: 1017 Comm: sa1 Tainted: G L 4.5.0-next-20160318+ #14

-
- when get_init_ra_size() gets called from ondemand_readahead().
-
- The net effect is that the initial readahead size is arch dependent for
- requested read lengths of zero: for example, since
-
- 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.

+commit a89837d0fc99aab94b5c8b975215de260271c1f7
+Author: Brad Spengler <spender@grsecurity.net>
+Date: Wed Apr 27 20:43:37 2016 -0400
+
+ Initial port of PaX to 4.5.2 with a limited form of RAP
+ (< 1/5th the total size of the full developed RAP plugin)
+ No retaddr protection via XOR canary
+ No C++ support
+ No LTO support
+ Removal of a few optimization passes
+ No compile time reporting of bad fptr casts
+
+ The RAP plugin should therefore be used only to compile an
+ appropriate vanilla kernel with this patch.

+ 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.

+ 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));
+
+ Prevents a splat due to skb_under_panic:

+ 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
+ and leaves del_timer_sync() at the close instead. This is because of
+ the restriction by the design of ALSA timer: namely, the stop callback
+ may be called from the timer handler, and calling the sync shall lead
+ to a hangup. However, this also triggers a kernel BUG() when the
+ timer is rearmed immediately after stopping without sync:
+ kernel BUG at kernel/time/timer.c:966!
+ Call Trace:
+ <IRQ>
+ [<ffffffff8239c94e>] snd_timer_s_start+0x13e/0x1a0
+ [<ffffffff8239e1f4>] snd_timer_interrupt+0x504/0xec0

+ [<ffffffff8239ebb0>] ? snd_timer_interrupt+0xec0/0xec0
+ ....
+
+ It's the place where add_timer() checks the pending timer. It's clear
+ that this may happen after the immediate restart without sync in our
+ cases.
+
+ So, the workaround here is just to use mod_timer() instead of
+ add_timer(). This looks like a band-aid fix, but it's a right move,
+ as snd_timer_interrupt() takes care of the continuous rearm of timer.

+ 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
+ unlocked DIO. However we now need to sometimes call it under i_mmap_sem
+ and sometimes not and DIO protection ranks above it (although strictly
+ speaking this cannot currently create any deadlocks). Also
+ ext4_zero_range() was actually getting & releasing unlocked DIO
+ protection twice in some cases. Luckily it didn't introduce any real bug

+
+ 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():
+
+ UBSAN: Undefined behaviour in crypto/asymmetric_keys/pkcs7_trust.c:194:14
+ load of value 82 is not a valid value for type '_Bool'
+ [...]
+ Call Trace:

+
+ The implication is that pkcs7_validate_trust() effectively grants trust
+ when it really shouldn't have.
+
+ Fix this by explicitly setting *_trusted to false at the very beginning
+ of 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'
+ CPU: 3 PID: 1017 Comm: sa1 Tainted: G L 4.5.0-next-20160318+ #14

+
+ when get_init_ra_size() gets called from ondemand_readahead().
+
+ The net effect is that the initial readahead size is arch dependent for
+ requested read lengths of zero: for example, since
+
+ 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.

+
+ 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.

+ 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

+ 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.

+commit a7817402ac837b1aee07fac42537a02097055098
+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.

+
+ 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.

+ 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).

+
+ 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.

+ ALSA: timer: Fix race among timer ioctls
+
+ ALSA timer ioctls have an open race and this may lead to a

+ ovs: limit ovs recursions in ovs_execute_actions to not corrupt stack
+
+ 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.
+
+ 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).
+
+ We use the already existing recursion counter in ovs_execute_actions to
+ implement an upper bound of 5 recursions.

+ As pointed out by Jann Horn, some distros are starting to circumvent
+ previous assumptions about the attainability of a user to control
+ multiple UIDs by handing out suid binaries that allow a user to run
+ processes (including exploits) under a number of other pre-defined
+ UIDs. As this could potentially be used to bypass GRKERNSEC_BRUTE
+ (though it would have to involve some code path that doesn't involve
+ locks) fix that here by ensuring no more than 8 users on a system can
+ be banned before a reboot is required. If more are banned, a panic
+ is triggered.

+ 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().

+ 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);
+ 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

+ block: ensure to split after potentially bouncing a bio
+
+ blk_queue_bio() does split then bounce, which makes the segment
+ counting based on pages before bouncing and could go wrong. Move

+ fix the issue of having the bio count for segments be wrong.

+
+ 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
