+Subject: afs: Fix in-progess ops to ignore server-level callback invalidation
+
+[ Upstream commit eeba1e9cf31d064284dd1fa7bd6cfe01395bd03d ]
+
+The in-kernel afs filesystem client counts the number of server-level
+callback invalidation events (CB.InitCallBackState* RPC operations) that it
+receives from the server. This is stored in cb_s_break in various
+structures, including afs_server and afs_vnode.
+
+If an inode is examined by afs_validate(), say, the afs_server copy is
+compared, along with other break counters, to those in afs_vnode, and if
+one or more of the counters do not match, it is considered that the
+server's callback promise is broken. At points where this happens,
+AFS_VNODE_CB_PROMISED is cleared to indicate that the status must be
+refetched from the server.
+
+afs_validate() issues an FS.FetchStatus operation to get updated metadata -
+and based on the updated data_version may invalidate the pagecache too.
+
+However, the break counters are also used to determine whether to note a
+new callback in the vnode (which would set the AFS_VNODE_CB_PROMISED flag)
+and whether to cache the permit data included in the YFSFetchStatus record
+by the server.
+
+The problem comes when the server sends us a CB.InitCallBackState op. The
+first such instance doesn't cause cb_s_break to be incremented, but rather
+causes AFS_SERVER_FL_NEW to be cleared - but thereafter, say some hours
+after last use and all the volumes have been automatically unmounted and
+the server has forgotten about the client[*], this *will* likely cause an
+increment.
+
+ [*] There are other circumstances too, such as the server restarting or
+ needing to make space in its callback table.
+
+Note that the server won't send us a CB.InitCallBackState op until we talk
+to it again.
+
+So what happens is:
+
+ (1) A mount for a new volume is attempted, a inode is created for the root
+ vnode and vnode->cb_s_break and AFS_VNODE_CB_PROMISED aren't set
+ immediately, as we don't have a nominated server to talk to yet - and
+ we may iterate through a few to find one.
+
+ (2) Before the operation happens, afs_fetch_status(), say, notes in the
+ cursor (fc.cb_break) the break counter sum from the vnode, volume and
+ server counters, but the server->cb_s_break is currently 0.
+
+ (3) We send FS.FetchStatus to the server. The server sends us back
+ CB.InitCallBackState. We increment server->cb_s_break.
+
+ (4) Our FS.FetchStatus completes. The reply includes a callback record.
+
+ (5) xdr_decode_AFSCallBack()/xdr_decode_YFSCallBack() check to see whether
+ the callback promise was broken by checking the break counter sum from
+ step (2) against the current sum.
+
+ This fails because of step (3), so we don't set the callback record
+ and, importantly, don't set AFS_VNODE_CB_PROMISED on the vnode.
+
+This does not preclude the syscall from progressing, and we don't loop here
+rechecking the status, but rather assume it's good enough for one round
+only and will need to be rechecked next time.
+
+ (6) afs_validate() it triggered on the vnode, probably called from
+ d_revalidate() checking the parent directory.
+
+ (7) afs_validate() notes that AFS_VNODE_CB_PROMISED isn't set, so doesn't
+ update vnode->cb_s_break and assumes the vnode to be invalid.
+
+ (8) afs_validate() needs to calls afs_fetch_status(). Go back to step (2)
+ and repeat, every time the vnode is validated.
+
+This primarily affects volume root dir vnodes. Everything subsequent to
+those inherit an already incremented cb_s_break upon mounting.
+
+The issue is that we assume that the callback record and the cached permit
+information in a reply from the server can't be trusted after getting a
+server break - but this is wrong since the server makes sure things are
+done in the right order, holding up our ops if necessary[*].
+
+ [*] There is an extremely unlikely scenario where a reply from before the
+ CB.InitCallBackState could get its delivery deferred till after - at
+ which point we think we have a promise when we don't. This, however,
+ requires unlucky mass packet loss to one call.
+
+AFS_SERVER_FL_NEW tries to paper over the cracks for the initial mount from
+a server we've never contacted before, but this should be unnecessary.
+It's also further insulated from the problem on an initial mount by
+querying the server first with FS.GetCapabilities, which triggers the
+CB.InitCallBackState.
+
+Fix this by
+
+ (1) Remove AFS_SERVER_FL_NEW.
+
+ (2) In afs_calc_vnode_cb_break(), don't include cb_s_break in the
+ calculation.
+
+ (3) In afs_cb_is_broken(), don't include cb_s_break in the check.

+Subject: ARM: fix function graph tracer and unwinder dependencies
+
+[ Upstream commit 503621628b32782a07b2318e4112bd4372aa3401 ]
+
+Naresh Kamboju recently reported that the function-graph tracer crashes
+on ARM. The function-graph tracer assumes that the kernel is built with
+frame pointers.
+
+We explicitly disabled the function-graph tracer when building Thumb2,
+since the Thumb2 ABI doesn't have frame pointers.
+
+We recently changed the way the unwinder method was selected, which
+seems to have made it more likely that we can end up with the function-
+graph tracer enabled but without the kernel built with frame pointers.
+
+Fix up the function graph tracer dependencies so the option is not
+available when we have no possibility of having frame pointers, and
+adjust the dependencies on the unwinder option to hide the non-frame
+pointer unwinder options if the function-graph tracer is enabled.

+[ Upstream commit 4e69ecf4da1ee0b2ac735e1f1bb13935acd5a38d ]
+
+Another bodge for the ftrace PLT code: plt_entries_equal() now takes
+the place relative nature of the ADRP/ADD based PLT entries into
+account, which means that a struct trampoline instance on the stack
+is no longer equal to the same set of opcodes in the module struct,
+given that they don't point to the same place in memory anymore.
+
+Work around this by using memcmp() in the ftrace PLT handling code.

+Subject: ceph: handle the case where a dentry has been renamed on outstanding
+ req
+
+[ Upstream commit 4b8222870032715f9d995f3eb7c7acd8379a275d ]
+
+It's possible for us to issue a lookup to revalidate a dentry
+concurrently with a rename. If done in the right order, then we could
+end up processing dentry info in the reply that no longer reflects the
+state of the dentry.
+
+If req->r_dentry->d_name differs from the one in the trace, then just
+ignore the trace in the reply. We only need to do this however if the
+parent's i_rwsem is not held.

+which is triggered by swapping to the sdhost interface.

+So instead of reintroduce the race condition again, we could also

+Subject: drm/amd/display: If one stream full updates, full update all planes
+
+[ Upstream commit c238bfe0be9ef7420f7669a69e27c8c8f4d8a568 ]
+
+[Why]
+On some compositors, with two monitors attached, VT terminal
+switch can cause a graphical issue by the following means:
+
+There are two streams, one for each monitor. Each stream has one
+plane
+
+current state:
+ M1:S1->P1
+ M2:S2->P2
+
+The user calls for a terminal switch and a commit is made to
+change both planes to linear swizzle mode. In atomic check,
+a new dc_state is constructed with new planes on each stream
+
+new state:
+ M1:S1->P3
+ M2:S2->P4
+
+In commit tail, each stream is committed, one at a time. The first
+stream (S1) updates properly, triggerring a full update and replacing
+the state
+
+current state:
+ M1:S1->P3
+ M2:S2->P4
+
+The update for S2 comes in, but dc detects that there is no difference
+between the stream and plane in the new and current states, and so
+triggers a fast update. The fast update does not program swizzle,
+so the second monitor is corrupted
+
+[How]
+Add a flag to dc_plane_state that forces full updates
+
+When a stream undergoes a full update, set this flag on all changed
+planes, then clear it on the current stream
+
+Subsequent streams will get full updates as a result

+
+shadow was added into shadow_list by amdgpu_bo_create_shadow.
+meanwhile, shadow->tbo.mem was not fully configured.
+tbo.mem would be fully configured by amdgpu_vm_sdma_map_table until calling amdgpu_vm_clear_bo.
+If sriov TDR occurred between amdgpu_bo_create_shadow and amdgpu_vm_sdma_map_table,
+amdgpu_device_recover_vram would deal with shadow without tbo.mem.start.

+
+Our components may still be using the DRM device driver (if only to

+the final drm_dev_put.
+
+Also release our reserved memory after component unbind instead of

+
+[ Upstream commit 7249c8ea227a582c14f63e9e8853eb7369122f10 ]
+
+When scatter to CQE is enabled on a DCT QP it corrupts the mailbox command
+since it tried to treat it as as QP create mailbox command instead of a
+DCT create command.
+
+The corrupted mailbox command causes userspace to malfunction as the
+device doesn't create the QP as expected.
+
+A new mlx5 capability is exposed to user-space which ensures that it will
+not enable the feature on DCT without this fix in the kernel.

+If probe errors out after request_irq(), its error path

+Subject: ipmi: ipmi_si_hardcode.c: init si_type array to fix a crash
+
+[ Upstream commit a885bcfd152f97b25005298ab2d6b741aed9b49c ]
+
+The intended behavior of function ipmi_hardcode_init_one() is to default
+to kcs interface when no type argument is presented when initializing
+ipmi with hard coded addresses.
+
+However, the array of char pointers allocated on the stack by function
+ipmi_hardcode_init() was not inited to zeroes, so it contained stack
+debris.
+
+Consequently, passing the cruft stored in this array to function
+ipmi_hardcode_init_one() caused a crash when it was unable to detect
+that the char * being passed was nonsense and tried to access the
+address specified by the bogus pointer.
+
+The fix is simply to initialize the si_type array to zeroes, so if
+there were no type argument given to at the command line, function
+ipmi_hardcode_init_one() could properly default to the kcs interface.

+
+[ Upstream commit 2b27924bb1d48e3775f432b70bdad5e6dd4e7798 ]
+
+The remaining failures of vmx.flat when EPT is disabled are caused by
+incorrectly reflecting VMfails to the L1 hypervisor. What happens is
+that nested_vmx_restore_host_state corrupts the guest CR3, reloading it
+with the host's shadow CR3 instead, because it blindly loads GUEST_CR3
+from the vmcs01.
+
+For simplicity let's just always use hardware VMCS checks when EPT is
+disabled. This way, nested_vmx_restore_host_state is not reached at
+all (or at least shouldn't be reached).

+Subject: KVM: nVMX: Expose RDPMC-exiting only when guest supports PMU
+
+[ Upstream commit e51bfdb68725dc052d16241ace40ea3140f938aa ]
+
+Issue was discovered when running kvm-unit-tests on KVM running as L1 on
+top of Hyper-V.
+
+When vmx_instruction_intercept unit-test attempts to run RDPMC to test
+RDPMC-exiting, it is intercepted by L1 KVM which it's EXIT_REASON_RDPMC
+handler raise #GP because vCPU exposed by Hyper-V doesn't support PMU.
+Instead of unit-test expectation to be reflected with EXIT_REASON_RDPMC.
+
+The reason vmx_instruction_intercept unit-test attempts to run RDPMC
+even though Hyper-V doesn't support PMU is because L1 expose to L2
+support for RDPMC-exiting. Which is reasonable to assume that is
+supported only in case CPU supports PMU to being with.
+
+Above issue can easily be simulated by modifying
+vmx_instruction_intercept config in x86/unittests.cfg to run QEMU with
+"-cpu host,+vmx,-pmu" and run unit-test.
+
+To handle issue, change KVM to expose RDPMC-exiting only when guest
+supports PMU.

+ in tracing
+
+[ Upstream commit 7a223e06b1a411cef6c4cd7a9b9a33c8d225b10e ]
+
+In __apic_accept_irq() interface trig_mode is int and actually on some code
+paths it is set above u8:
+
+kvm_apic_set_irq() extracts it from 'struct kvm_lapic_irq' where trig_mode
+is u16. This is done on purpose as e.g. kvm_set_msi_irq() sets it to
+(1 << 15) & e->msi.data
+
+kvm_apic_local_deliver sets it to reg & (1 << 15).
+
+Fix the immediate issue by making 'tm' into u16. We may also want to adjust
+__apic_accept_irq() interface and use proper sizes for vector, level,
+trig_mode but this is not urgent.

+
+[ Upstream commit 672ff6cff80ca43bf3258410d2b887036969df5f ]
+
+Before this change, reading a VMware pseduo PMC will succeed even when
+PMU is not supported by guest. This can easily be seen by running
+kvm-unit-test vmware_backdoors with "-cpu host,-pmu" option.

+Subject: libnvdimm/security: provide fix for secure-erase to use zero-key
+
+[ Upstream commit 037c8489ade669e0f09ad40d5b91e5e1159a14b1 ]
+
+Add a zero key in order to standardize hardware that want a key of 0's to
+be passed. Some platforms defaults to a zero-key with security enabled
+rather than allow the OS to enable the security. The zero key would allow
+us to manage those platform as well. This also adds a fix to secure erase
+so it can use the zero key to do crypto erase. Some other security commands
+already use zero keys. This introduces a standard zero-key to allow
+unification of semantics cross nvdimm security commands.

+
+This problem is happening, because currently statically assigned virtual
+IRQ 13 for performance counters is not claimed during the initialization
+of MIPS PMU during the bootup, so the IRQ subsystem doesn't know, that
+this interrupt isn't available for further use.
+
+So this patch fixes the issue by simply booking hardware IRQ 5 for MIPS PMU.

+
+[ Upstream commit 3b991208b897f52507168374033771a984b947b1 ]
+
+During !CONFIG_CGROUP reclaim, we expand the inactive list size if it's
+thrashing on the node that is about to be reclaimed. But when cgroups
+are enabled, we suddenly ignore the node scope and use the cgroup scope
+only. The result is that pressure bleeds between NUMA nodes depending
+on whether cgroups are merely compiled into Linux. This behavioral
+difference is unexpected and undesirable.
+
+When the refault adaptivity of the inactive list was first introduced,
+there were no statistics at the lruvec level - the intersection of node
+and memcg - so it was better than nothing.
+
+But now that we have that infrastructure, use lruvec_page_state() to
+make the list balancing decision always NUMA aware.

+Subject: mm/hotplug: treat CMA pages as unmovable
+
+[ Upstream commit 1a9f219157b22d0ffb340a9c5f431afd02cd2cf3 ]
+
+has_unmovable_pages() is used by allocating CMA and gigantic pages as
+well as the memory hotplug. The later doesn't know how to offline CMA
+pool properly now, but if an unused (free) CMA page is encountered, then
+has_unmovable_pages() happily considers it as a free memory and
+propagates this up the call chain. Memory offlining code then frees the
+page without a proper CMA tear down which leads to an accounting issues.
+Moreover if the same memory range is onlined again then the memory never
+gets back to the CMA pool.
+
+State after memory offline:
+
+ # grep cma /proc/vmstat
+ nr_free_cma 205824
+
+ # cat /sys/kernel/debug/cma/cma-kvm_cma/count
+ 209920
+
+Also, kmemleak still think those memory address are reserved below but
+have already been used by the buddy allocator after onlining. This
+patch fixes the situation by treating CMA pageblocks as unmovable except
+when has_unmovable_pages() is called as part of CMA allocation.

+Right now we are using find_memory_block() to get the node id for the

+Subject: net: sched: fix cleanup NULL pointer exception in act_mirr
+
+[ Upstream commit 064c5d6881e897077639e04973de26440ee205e6 ]
+
+A new mirred action is created by the tcf_mirred_init function. This
+contains a list head struct which is inserted into a global list on
+successful creation of a new action. However, after a creation, it is
+still possible to error out and call the tcf_idr_release function. This,
+in turn, calls the act_mirr cleanup function via __tcf_idr_release and
+__tcf_action_put. This cleanup function tries to delete the list entry
+which is as yet uninitialised, leading to a NULL pointer exception.
+
+Fix this by initialising the list entry on creation of a new action.
+
+Bug report:

+OR sysctl_log_invalid isn't equal to IPPROTO_RAW. This sentence is

+Subject: netfilter: nat: fix icmp id randomization
+
+[ Upstream commit 5bdac418f33f60b07a34e01e722889140ee8fac9 ]
+
+Sven Auhagen reported that a 2nd ping request will fail if 'fully-random'
+mode is used.
+
+Reason is that if no proto information is given, min/max are both 0,
+so we set the icmp id to 0 instead of chosing a random value between
+0 and 65535.
+
+Update test case as well to catch this, without fix this yields:
+[..]
+ERROR: cannot ping ns1 from ns2 with ip masquerade fully-random (attempt 2)
+ERROR: cannot ping ns1 from ns2 with ipv6 masquerade fully-random (attempt 2)
+
+... becaus 2nd ping clashes with existing 'id 0' icmp conntrack and gets
+dropped.

+Subject: netfilter: never get/set skb->tstamp
+
+[ Upstream commit 916f6efae62305796e012e7c3a7884a267cbacbf ]
+
+setting net.netfilter.nf_conntrack_timestamp=1 breaks xmit with fq
+scheduler. skb->tstamp might be "refreshed" using ktime_get_real(),
+but fq expects CLOCK_MONOTONIC.
+
+This patch removes all places in netfilter that check/set skb->tstamp:
+
+1. To fix the bogus "start" time seen with conntrack timestamping for
+ outgoing packets, never use skb->tstamp and always use current time.
+2. In nfqueue and nflog, only use skb->tstamp for incoming packets,
+ as determined by current hook (prerouting, input, forward).
+3. xt_time has to use system clock as well rather than skb->tstamp.
+ We could still use skb->tstamp for prerouting/input/foward, but
+ I see no advantage to make this conditional.
+
+Fixes: fb420d5d91c1 ("tcp/fq: move back to CLOCK_MONOTONIC")

+MIME-Version: 1.0

+Content-Transfer-Encoding: 8bit
+
+[ Upstream commit 36ad7022536e0c65f8baeeaa5efde11dec44808a ]
+
+I've discovered following discrepancy in the bindings/net/ethernet.txt
+documentation, where it states following:
+
+ - nvmem-cells: phandle, reference to an nvmem node for the MAC address;
+ - nvmem-cell-names: string, should be "mac-address" if nvmem is to be..
+
+which is actually misleading and confusing. There are only two ethernet
+drivers in the tree, cadence/macb and davinci which supports this
+properties.
+
+This nvmem-cell* properties were introduced in commit 9217e566bdee
+("of_net: Implement of_get_nvmem_mac_address helper"), but
+commit afa64a72b862 ("of: net: kill of_get_nvmem_mac_address()")
+forget to properly clean up this parts.
+
+So this patch fixes the documentation by moving the nvmem-cell*
+properties at the appropriate places. While at it, I've removed unused
+include as well.

+Subject: perf tools: Fix map reference counting
+
+[ Upstream commit b9abbdfa88024d52c8084d8f46ea4f161606c692 ]

+By calling maps__insert() we assume to get 2 references on the map,
+which we relese within maps__remove call.
+
+However if there's already same map name, we currently don't bump the
+reference and can crash, like:

+Subject: perf top: Always sample time to satisfy needs of use of ordered
+ queuing
+
+[ Upstream commit 1e6db2ee86e6a4399fc0ae5689e55e0fd1c43caf ]
+
+Bastian reported broken 'perf top -p PID' command, it won't display any
+data.
+
+The problem is that for -p option we monitor single thread, so we don't
+enable time in samples, because it's not needed.
+
+However since commit 16c66bc167cc we use ordered queues to stash data
+plus later commits added logic for dropping samples in case there's big
+load and we don't keep up. All this needs timestamp for sample. Enabling
+it unconditionally for perf top.

+Subject: qed: Delete redundant doorbell recovery types
+
+[ Upstream commit 9ac6bb1414ac0d45fe9cefbd1f5b06f0e1a3c98a ]
+
+DB_REC_DRY_RUN (running doorbell recovery without sending doorbells) is
+never used. DB_REC_ONCE (send a single doorbell from the doorbell recovery)
+is not needed anymore because by running the periodic handler we make sure
+we check the overflow status later instead.
+This patch is needed because in the next patches, the only doorbell
+recovery type being used is DB_REC_REAL_DEAL, and the fixes are much
+cleaner without this enum.

+Subject: qed: Fix missing DORQ attentions
+
+[ Upstream commit d4476b8a6151b2dd86c09b5acec64f66430db55d ]
+
+When the DORQ (doorbell block) is overflowed, all PFs get attentions at the
+same time. If one PF finished handling the attention before another PF even
+started, the second PF might miss the DORQ's attention bit and not handle
+the attention at all.
+If the DORQ attention is missed and the issue is not resolved, another
+attention will not be sent, therefore each attention is treated as a
+potential DORQ attention.
+As a result, the attention callback is called more frequently so the debug
+print was moved to reduce its quantity.
+The number of periodic doorbell recovery handler schedules was reduced
+because it was the previous way to mitigating the missed attention issue.

+Subject: qed: Fix the DORQ's attentions handling
+
+[ Upstream commit 0d72c2ac89185f179da1e8a91c40c82f3fa38f0b ]
+
+Separate the overflow handling from the hardware interrupt status analysis.
+The interrupt status is a single register and is common for all PFs. The
+first PF reading the register is not necessarily the one who overflowed.
+All PFs must check their overflow status on every attention.
+In this change we clear the sticky indication in the attention handler to
+allow doorbells to be processed again as soon as possible, but running
+the doorbell recovery is scheduled for the periodic handler to reduce the
+time spent in the attention handler.
+Checking the need for DORQ flush was changed to "db_bar_no_edpm" because
+qed_edpm_enabled()'s result could change dynamically and might have
+prevented a needed flush.

+Subject: qede: fix write to free'd pointer error and double free of ptp
+
+[ Upstream commit 1dc2b3d65523780ed1972d446c76e62e13f3e8f5 ]
+
+The err2 error return path calls qede_ptp_disable that cleans up
+on an error and frees ptp. After this, the free'd ptp is dereferenced
+when ptp->clock is set to NULL and the code falls-through to error
+path err1 that frees ptp again.
+
+Fix this by calling qede_ptp_disable and exiting via an error
+return path that does not set ptp->clock or kfree ptp.

+Subject: RDMA/hns: Bugfix for mapping user db
+
+[ Upstream commit 2557fabd6e29f349bfa0ac13f38ac98aa5eafc74 ]
+
+When the maximum send wr delivered by the user is zero, the qp does not
+have a sq.
+
+When allocating the sq db buffer to store the user sq pi pointer and map
+it to the kernel mode, max_send_wr is used as the trigger condition, while
+the kernel does not consider the max_send_wr trigger condition when
+mapmping db. It will cause sq record doorbell map fail and create qp fail.
+
+The failed print information as follows:
+
+ hns3 0000:7d:00.1: Send cmd: tail - 418, opcode - 0x8504, flag - 0x0011, retval - 0x0000

+
+[ Upstream commit a0cecc23cfcbf2626497a8c8770856dd56b67917 ]
+
+This patch does more harm than good, as it breaks both Xwayland and
+gnome-shell with X11.
+
+Xwayland requires DRI3 & DRI3 requires PRIME.
+
+X11 crash for obscure double-free reason which are hard to debug
+(starting X11 by hand doesn't trigger the crash).
+
+I don't see an apparent problem implementing those stub prime
+functions, they may return an error at run-time, and it seems to be
+handled fine by GNOME at least.
+
+This reverts commit b318e3ff7ca065d6b107e424c85a63d7a6798a69.
+[airlied:
+This broke userspace for virtio-gpus, and regressed things from DRI3 to DRI2.

+Subject: s390/dasd: Fix capacity calculation for large volumes
+
+[ Upstream commit 2cc9637ce825f3a9f51f8f78af7474e9e85bfa5f ]
+
+The DASD driver incorrectly limits the maximum number of blocks of ECKD
+DASD volumes to 32 bit numbers. Volumes with a capacity greater than
+2^32-1 blocks are incorrectly recognized as smaller volumes.
+
+This results in the following volume capacity limits depending on the
+formatted block size:
+
+ BLKSIZE MAX_GB MAX_CYL
+ 512 2047 5843492
+ 1024 4095 8676701
+ 2048 8191 13634816
+ 4096 16383 23860929
+
+The same problem occurs when a volume with more than 17895697 cylinders
+is accessed in raw-track-access mode.
+
+Fix this problem by adding an explicit type cast when calculating the
+maximum number of blocks.

+[ Upstream commit 6b1f16ba730d4c0cda1247568c3a1bf4fa3a2f2f ]
+
+The debug feature entries have been used with up to 5 arguents
+(including the pointer to the format string) but there was only
+space reserved for 4 arguemnts. So now the registration does
+reserve space for 5 times a long value.
+
+This fixes a sometime appearing weired value as the last
+value of an debug feature entry like this:
+
+... pkey_sec2protkey zcrypt_send_cprb (cardnr=10 domain=12)
+ failed with errno -2143346254

+Subject: selftests: fib_tests: Fix 'Command line is not complete' errors
+
+[ Upstream commit a5f622984a623df9a84cf43f6b098d8dd76fbe05 ]
+
+A couple of tests are verifying a route has been removed. The helper
+expects the prefix as the first part of the expected output. When
+checking that a route has been deleted the prefix is empty leading
+to an invalid ip command:
+
+ $ ip ro ls match
+ Command line is not complete. Try option "help"
+
+Fix by moving the comparison of expected output and output to a new
+function that is used by both check_route and check_route6. Use the
+new helper for the 2 checks on route removal.
+
+Also, remove the reset of 'set -x' in route_setup which overrides the
+user managed setting.

+
+[ Upstream commit 30c04d796b693e22405c38e9b78e9a364e4c77e6 ]
+
+The run_netsocktests will be marked as passed regardless the actual test
+result from the ./socket:
+
+ selftests: net: run_netsocktests
+ ========================================
+ --------------------
+ running socket test
+ --------------------
+ [FAIL]
+ ok 1..6 selftests: net: run_netsocktests [PASS]
+
+This is because the test script itself has been successfully executed.
+Fix this by exit 1 when the test failed.

+Subject: selftests: netfilter: check icmp pkttoobig errors are set as related
+
+[ Upstream commit becf2319f320cae43e20cf179cc51a355a0deb5f ]
+
+When an icmp error such as pkttoobig is received, conntrack checks
+if the "inner" header (header of packet that did not fit link mtu)
+is matches an existing connection, and, if so, sets that packet as
+being related to the conntrack entry it found.
+
+It was recently reported that this "related" setting also works
+if the inner header is from another, different connection (i.e.,
+artificial/forged icmp error).
+
+Add a test, followup patch will add additional "inner dst matches
+outer dst in reverse direction" check before setting related state.

+Subject: slab: store tagged freelist for off-slab slabmgmt
+
+[ Upstream commit 1a62b18d51e5c5ecc0345c85bb9fef870ab721ed ]
+
+Commit 51dedad06b5f ("kasan, slab: make freelist stored without tags")
+calls kasan_reset_tag() for off-slab slab management object leading to
+freelist being stored non-tagged.
+
+However, cache_grow_begin() calls alloc_slabmgmt() which calls
+kmem_cache_alloc_node() assigns a tag for the address and stores it in
+the shadow address. As the result, it causes endless errors below
+during boot due to drain_freelist() -> slab_destroy() ->
+kasan_slab_free() which compares already untagged freelist against the
+stored tag in the shadow address.
+
+Since off-slab slab management object freelist is such a special case,
+just store it tagged. Non-off-slab management object freelist is still
+stored untagged which has not been assigned a tag and should not cause
+any other troubles with this inconsistency.

+Subject: tools lib traceevent: Fix missing equality check for strcmp
+
+[ Upstream commit f32c2877bcb068a718bb70094cd59ccc29d4d082 ]
+
+There was a missing comparison with 0 when checking if type is "s64" or
+"u64". Therefore, the body of the if-statement was entered if "type" was
+"u64" or not "s64", which made the first strcmp() redundant since if
+type is "u64", it's not "s64".
+
+If type is "s64", the body of the if-statement is not entered but since
+the remainder of the function consists of if-statements which will not
+be entered if type is "s64", we will just return "val", which is
+correct, albeit at the cost of a few more calls to strcmp(), i.e., it
+will behave just as if the if-statement was entered.
+
+If type is neither "s64" or "u64", the body of the if-statement will be
+entered incorrectly and "val" returned. This means that any type that is
+checked after "s64" and "u64" is handled the same way as "s64" and
+"u64", i.e., the limiting of "val" to fit in for example "s8" is never
+reached.
+
+This was introduced in the kernel tree when the sources were copied from
+trace-cmd in commit f7d82350e597 ("tools/events: Add files to create
+libtraceevent.a"), and in the trace-cmd repo in 1cdbae6035cei
+("Implement typecasting in parser") when the function was introduced,
+i.e., it has always behaved the wrong way.
+
+Detected by cppcheck.

+Subject: x86/build/lto: Fix truncated .bss with -fdata-sections
+
+[ Upstream commit 6a03469a1edc94da52b65478f1e00837add869a3 ]
+
+With CONFIG_LD_DEAD_CODE_DATA_ELIMINATION=y, we compile the kernel with
+-fdata-sections, which also splits the .bss section.
+
+The new section, with a new .bss.* name, which pattern gets missed by the
+main x86 linker script which only expects the '.bss' name. This results
+in the discarding of the second part and a too small, truncated .bss
+section and an unhappy, non-working kernel.
+
+Use the common BSS_MAIN macro in the linker script to properly capture
+and merge all the generated BSS sections.

+
+[ Upstream commit 510bb96fe5b3480b4b22d815786377e54cb701e7 ]
+
+Xose Vazquez Perez reported boot warnings when NX is disabled on the kernel command line.
+
+__early_set_fixmap() triggers this warning:
+
+ attempted to set unsupported pgprot: 8000000000000163
+ bits: 8000000000000000

+
+ WARNING: CPU: 0 PID: 0 at arch/x86/include/asm/pgtable.h:537
+ __early_set_fixmap+0xa2/0xff
+
+because it uses __default_kernel_pte_mask to mask out unsupported bits.
+
+Use __supported_pte_mask instead.
+
+Disabling NX on the command line also triggers the NX warning in the page
+table mapping check:
+
+ WARNING: CPU: 1 PID: 1 at arch/x86/mm/dump_pagetables.c:262 note_page+0x2ae/0x650

+Subject: x86/reboot, efi: Use EFI reboot for Acer TravelMate X514-51T
+
+[ Upstream commit 0082517fa4bce073e7cf542633439f26538a14cc ]
+
+Upon reboot, the Acer TravelMate X514-51T laptop appears to complete the
+shutdown process, but then it hangs in BIOS POST with a black screen.
+
+The problem is intermittent - at some points it has appeared related to
+Secure Boot settings or different kernel builds, but ultimately we have
+not been able to identify the exact conditions that trigger the issue to
+come and go.
+
+Besides, the EFI mode cannot be disabled in the BIOS of this model.
+
+However, after extensive testing, we observe that using the EFI reboot
+method reliably avoids the issue in all cases.
+
+So add a boot time quirk to use EFI reboot on such systems.
