perf tools updates for v5.10: 3rd batch.
- Fix file corruption due to event deletion in 'perf inject'.
- Update arch/x86/lib/mem{cpy,set}_64.S copies used in 'perf bench mem
memcpy', silencing perf build warning.
- Avoid an msan warning in a copied stack in 'perf test'.
- Correct tracepoint field name "flags" in ARM's CS-ETM hardware tracing
'perf test' entry.
- Update branch sample pattern for cs-etm to cope with excluding guest
in userspace counting.
- Don't free "lock_seq_stat" if read_count isn't zero in 'perf lock'.
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Merge branch 'urgent-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu
Pull RCU fix from Paul McKenney: "A single commit that fixes a bug that was introduced a couple of merge windows ago, but which rather more recently converged to an agreed-upon fix. The bug is that interrupts can be incorrectly enabled while holding an irq-disabled spinlock. This can of course result in self-deadlocks. The bug is a bit difficult to trigger. It requires that a preempted task be blocking a preemptible-RCU grace period long enough to trigger an RCU CPU stall warning. In addition, an interrupt must occur at just the right time, and that interrupt's handler must acquire that same irq-disabled spinlock. Still, a deadlock is a deadlock. Furthermore, we do now have a fix, and that fix survives kernel test robot, -next, and rcutorture testing. It has also been verified by Sebastian as fixing the bug. Therefore..." * 'urgent-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: rcu: Don't invoke try_invoke_on_locked_down_task() with irqs disabled |

ARM: SoC fixes for v5.10, part 2
Around one third of the fixes this time are for dts files that list their ethernet controller as using 'phy-mode="rgmii"' but are changed to 'phy-mode="rgmii-id"' now, because the PHY drivers (realtek, ksz9031, dp83867, ...) now configure the internal delay based on that when they used to stay on the hardware default. The long story is archived at https://lore.kernel.org/netdev/CAMj1kXEEF_Un-4NTaD5iUN0NoZYaJQn-rPediX0S6oRiuVuW-A@mail.gmail.com/ I was trying to hold off on the bugfixes until there was a solution that would avoid breaking all boards, but that does not seem to be happening any time soon, so I am now sending the correct version of the dts files to ensure that at least these machines can use their network devices again. The other changes this time are: - Updating the MAINTAINER lists for Allwinner and Samsung SoCs - Multiple i.MX8MN machines get updates for their CPU operating points to match the data sheet - A revert for a dts patch that caused a regression in USB support on Odroid U3 - Two fixes for the AMD Tee driver, addressing a memory leak and missing locking - Mark the network subsystem on qoriq-fman3 as cache coherent for correctness as better performance. - Minor dts fixes elsewhere, addressing dtc warnings and similar problems Signed-off-by: Arnd Bergmann <arnd@arndb.de> -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAl+yqIMACgkQmmx57+YA GNniQxAAnv8RAPMt8Jv4tyA0RshkD5+6JtgD6KfYccbI5Df+1O3YKJm90SA4Tpwg 03GHpAsgIs9SYNP7gSs9HPYCOJwC4rmgmfbnbB4Ezpr+oe+w6C8FI7160BBgb4f8 3/0LC6YyF48SPJ40lF/GOnTLbD5hxGw08oHCh/oL+b+bwn21JZoXAtkloCz8o6Ax u98G5MAaJhoTFaE3jq+8F1t6PNJ518HTulzod7uLAjn4iQtAmE96J7q9ncwcGu6a HNNcAGuz7X5QfEwWuAJai8eWvtMyGLvB5x1LXjjCNKgIqG+cD1tqpQ3FMedi36fg N+fxMxTJKuvBaQ83h/yyNk4/W3h6ddTbuEH0s320xSP5eiZ4r+/2Ry3WPHxHR3Rq YYDFbN6I19pQmgedJhgEmUEJXMcyId4SqN85l+uB58lOzu4zGf4WwVd+CBnEoIu3 wMGHbwruP1t+4hvZjiga53iOzWTR2EzTYkKxfDrV3mPZY6gmov5Xjb0JZNl164WF 0IJEa61HKf/ueJ5UNwWXpObNyD9rD2Ucugvok/KC1s06NFKjebGK4JhwChxMN0Sk baynLGSDe8utENrYgW+KmgZTQHTEICimT5ogW7H+W3trXqxvTKpwCsv5zZM0e238 vULK/YGZLQZaZrxsCG2WylL6SlJQfptMy8wzOoKmbgTOkcsBasA= =Qgm/ -----END PGP SIGNATURE----- Merge tag 'arm-soc-fixes-v5.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC fixes from Arnd Bergmann: "Around one third of the fixes this time are for dts files that list their ethernet controller as using 'phy-mode="rgmii"' but are changed to 'phy-mode="rgmii-id"' now, because the PHY drivers (realtek, ksz9031, dp83867, ...) now configure the internal delay based on that when they used to stay on the hardware default.

perf test: Avoid an msan warning in a copied stack.
This fix is for a failure that occurred in the DWARF unwind perf test.
Stack unwinders may probe memory when looking for frames.
Memory sanitizer will poison and track uninitialized memory on the
stack, and on the heap if the value is copied to the heap.
This can lead to false memory sanitizer failures for the use of an
uninitialized value.
Avoid this problem by removing the poison on the copied stack.
The full msan failure with track origins looks like:

perf inject: Fix file corruption due to event deletion
"perf inject" can create corrupt files when synthesizing sample events from AUX
data. This happens when in the input file, the first event (for the AUX data)
has a different sample_type from the second event (generally dummy).
Specifically, they differ in the bits that indicate the standard fields
appended to perf records in the mmap buffer. "perf inject" deletes the first
event and moves up the second event to first position.
The problem is with the synthetic PERF_RECORD_MMAP (etc.) events created
by "perf record".
Since these are synthetic versions of events which are normally produced
by the kernel, they have to have the standard fields appended as
described by sample_type.
"perf record" fills these in with zeroes, including the IDENTIFIER
field; perf readers interpret records with zero IDENTIFIER using the
descriptor for the first event in the file.
Since "perf inject" changes the first event, these synthetic records are
then processed with the wrong value of sample_type, and the perf reader
reads bad data, reports on incorrect length records etc.
Mismatching sample_types are seen with "perf record -e cs_etm//", where the AUX
event has TID|TIME|CPU|IDENTIFIER and the dummy event has TID|TIME|IDENTIFIER.
Perhaps they could be the same, but it isn't normally a problem if they aren't
- perf has no problems reading the file.
The sample_types have to agree on the position of IDENTIFIER, because
that's how perf finds the right event descriptor in the first place, but
they don't normally have to agree on other fields, and perf doesn't
check that they do.
The problem is specific to the way "perf inject" reorganizes the events
and the way synthetic MMAP events are recorded with a zero identifier. A
simple solution is to stop "perf inject" deleting the tracing event.
Committer testing
Removed the now unused 'evsel' variable, update the comment about the
evsel removal not being performed anymore, and apply the patch manually
as it failed with this warning:

vhost scsi: Add support for LUN resets.
In newer versions of virtio-scsi we just reset the timer when an a command times out, so TMFs are never sent for the cmd time out case. However, in older kernels and for the TMF inject cases, we can still get resets and we end up just failing immediately so the guest might see the device get offlined and IO errors. For the older kernel cases, we want the same end result as the modern virtio-scsi driver where we let the lower levels fire their error handling and handle the problem. And at the upper levels we want to wait. This patch ties the LUN reset handling into the LIO TMF code which will just wait for outstanding commands to complete like we are doing in the modern virtio-scsi case. Note: I did not handle the ABORT case to keep this simple. For ABORTs LIO just waits on the cmd like how it does for the RESET case. If an ABORT fails, the guest OS ends up escalating to LUN RESET, so in the end we get the same behavior where we wait on the outstanding cmds.

vhost scsi: fix cmd completion race
We might not do the final se_cmd put from vhost_scsi_complete_cmd_work. When the last put happens a little later then we could race where vhost_scsi_complete_cmd_work does vhost_signal, the guest runs and sends more IO, and vhost_scsi_handle_vq runs but does not find any free cmds. This patch has us delay completing the cmd until the last lio core ref is dropped. We then know that once we signal to the guest that the cmd is completed that if it queues a new command it will find a free cmd.

vhost scsi: alloc cmds per vq instead of session
We currently are limited to 256 cmds per session. This leads to problems where if the user has increased virtqueue_size to more than 2 or cmd_per_lun to more than 256 vhost_scsi_get_tag can fail and the guest will get IO errors. This patch moves the cmd allocation to per vq so we can easily match whatever the user has specified for num_queues and virtqueue_size/cmd_per_lun. It also makes it easier to control how much memory we preallocate. For cases, where perf is not as important and we can use the current defaults (1 vq and 128 cmds per vq) memory use from preallocate cmds is cut in half. For cases, where we are willing to use more memory for higher perf, cmd mem use will now increase as the num queues and queue depth increases.

A small set of fixes for x86:
- Cure the fallout from the MSI irqdomain overhaul which missed that the
Intel IOMMU does not register virtual function devices and therefore
never reaches the point where the MSI interrupt domain is assigned. This
makes the VF devices use the non-remapped MSI domain which is trapped by
the IOMMU/remap unit.
- Remove an extra space in the SGI_UV architecture type procfs output for
UV5.
- Remove a unused function which was missed when removing the UV BAU TLB
shootdown handler.

A set of fixes for perf:
- A set of commits which reduce the stack usage of various perf event
handling functions which allocated large data structs on stack causing
stack overflows in the worst case.
- Use the proper mechanism for detecting soft interrupts in the recursion
protection.
- Make the resursion protection simpler and more robust.
- Simplify the scheduling of event groups to make the code more robust and
prepare for fixing the issues vs. scheduling of exclusive event groups.
- Prevent event multiplexing and rotation for exclusive event groups
- Correct the perf event attribute exclusive semantics to take pinned
events, e.g. the PMU watchdog, into account
- Make the anythread filtering conditional for Intel's generic PMU
counters as it is not longer guaranteed to be supported on newer
CPUs. Check the corresponding CPUID leaf to make sure.
- Fixup a duplicate initialization in an array which was probably cause by
the usual copy & paste - forgot to edit mishap.

A set of scheduler fixes:
- Address a load balancer regression by making the load balancer use the
same logic as the wakeup path to spread tasks in the LLC domain.
- Prefer the CPU on which a task run last over the local CPU in the fast
wakeup path for asymmetric CPU capacity systems to align with the
symmetric case. This ensures more locality and prevents massive
migration overhead on those asymetric systems
- Fix a memory corruption bug in the scheduler debug code caused by
handing a modified buffer pointer to kfree().

Two fixes for the locking subsystem:
- Prevent an unconditional interrupt enable in a futex helper function
which can be called from contexts which expect interrupts to stay
disabled across the call.
- Don't modify lockdep chain keys in the validation process as that
causes chain inconsistency.

kvm: mmu: fix is_tdp_mmu_check when the TDP MMU is not in use
In some cases where shadow paging is in use, the root page will be either mmu->pae_root or vcpu->arch.mmu->lm_root. Then it will not have an associated struct kvm_mmu_page, because it is allocated with alloc_page instead of kvm_mmu_alloc_page. Just return false quickly from is_tdp_mmu_root if the TDP MMU is not in use, which also includes the case where shadow paging is enabled. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |

afs: Fix afs_write_end() when called with copied == 0 [ver #3]
When afs_write_end() is called with copied == 0, it tries to set the
dirty region, but there's no way to actually encode a 0-length region in
the encoding in page->private.
"0,0", for example, indicates a 1-byte region at offset 0. The maths
miscalculates this and sets it incorrectly.
Fix it to just do nothing but unlock and put the page in this case. We
don't actually need to mark the page dirty as nothing presumably
changed.

ocfs2: initialize ip_next_orphan
Though problem if found on a lower 4.1.12 kernel, I think upstream has
same issue.
In one node in the cluster, there is the following callback trace:
# cat /proc/21473/stack
__ocfs2_cluster_lock.isra.36+0x336/0x9e0 [ocfs2]
ocfs2_inode_lock_full_nested+0x121/0x520 [ocfs2]
ocfs2_evict_inode+0x152/0x820 [ocfs2]
evict+0xae/0x1a0
iput+0x1c6/0x230
ocfs2_orphan_filldir+0x5d/0x100 [ocfs2]
ocfs2_dir_foreach_blk+0x490/0x4f0 [ocfs2]
ocfs2_dir_foreach+0x29/0x30 [ocfs2]
ocfs2_recover_orphans+0x1b6/0x9a0 [ocfs2]
ocfs2_complete_recovery+0x1de/0x5c0 [ocfs2]
process_one_work+0x169/0x4a0
worker_thread+0x5b/0x560
kthread+0xcb/0xf0
ret_from_fork+0x61/0x90
The above stack is not reasonable, the final iput shouldn't happen in
ocfs2_orphan_filldir() function. Looking at the code,
2067 /* Skip inodes which are already added to recover list, since dio may
2068 * happen concurrently with unlink/rename */
2069 if (OCFS2_I(iter)->ip_next_orphan) {
2070 iput(iter);
2071 return 0;
2072 }
2073
The logic thinks the inode is already in recover list on seeing
ip_next_orphan is non-NULL, so it skip this inode after dropping a
reference which incremented in ocfs2_iget().
While, if the inode is already in recover list, it should have another
reference and the iput() at line 2070 should not be the final iput
(dropping the last reference). So I don't think the inode is really in
the recover list (no vmcore to confirm).
Note that ocfs2_queue_orphans(), though not shown up in the call back
trace, is holding cluster lock on the orphan directory when looking up
for unlinked inodes. The on disk inode eviction could involve a lot of
IOs which may need long time to finish. That means this node could hold
the cluster lock for very long time, that can lead to the lock requests
(from other nodes) to the orhpan directory hang for long time.
Looking at more on ip_next_orphan, I found it's not initialized when
allocating a new ocfs2_inode_info structure.
This causes te reflink operations from some nodes hang for very long
time waiting for the cluster lock on the orphan directory.
Fix: initialize ip_next_orphan as NULL.

hugetlbfs: fix anon huge page migration race
Qian Cai reported the following BUG in [1]
LTP: starting move_pages12
BUG: unable to handle page fault for address: ffffffffffffffe0
...
RIP: 0010:anon_vma_interval_tree_iter_first+0xa2/0x170 avc_start_pgoff at mm/interval_tree.c:63
Call Trace:

entry_SYSCALL_64_after_hwframe+0x44/0xa9
Hugh Dickins diagnosed this as a migration bug caused by code introduced
to use i_mmap_rwsem for pmd sharing synchronization. Specifically, the
routine unmap_and_move_huge_page() is always passing the TTU_RMAP_LOCKED
flag to try_to_unmap() while holding i_mmap_rwsem. This is wrong for
anon pages as the anon_vma_lock should be held in this case. Further
analysis suggested that i_mmap_rwsem was not required to he held at all
when calling try_to_unmap for anon pages as an anon page could never be
part of a shared pmd mapping.
Discussion also revealed that the hack in hugetlb_page_mapping_lock_write
to drop page lock and acquire i_mmap_rwsem is wrong. There is no way to
keep mapping valid while dropping page lock.
This patch does the following:
- Do not take i_mmap_rwsem and set TTU_RMAP_LOCKED for anon pages when
calling try_to_unmap.
- Remove the hacky code in hugetlb_page_mapping_lock_write. The routine
will now simply do a 'trylock' while still holding the page lock. If
the trylock fails, it will return NULL. This could impact the
callers:
- migration calling code will receive -EAGAIN and retry up to the
hard coded limit (10).
- memory error code will treat the page as BUSY. This will force
killing (SIGKILL) instead of SIGBUS any mapping tasks.
Do note that this change in behavior only happens when there is a
race. None of the standard kernel testing suites actually hit this
race, but it is possible.

mm/gup: use unpin_user_pages() in __gup_longterm_locked()
When FOLL_PIN is passed to __get_user_pages() the page list must be put
back using unpin_user_pages() otherwise the page pin reference persists
in a corrupted state.
There are two places in the unwind of __gup_longterm_locked() that put
the pages back without checking. Normally on error this function would
return the partial page list making this the caller's responsibility,
but in these two cases the caller is not allowed to see these pages at
all.
