Alexey reported that the fraction of unknown filename instances in
kallsyms grew from ~0.3% to ~10% recently; Bill and Greg tracked it down
to assembler defined symbols, which regressed as a result of:
commit b8a9092330 ("Kbuild: do not emit debug info for assembly with LLVM_IAS=1")
In that commit, I allude to restoring debug info for assembler defined
symbols in a follow up patch, but it seems I forgot to do so in

Before GCC 11 and Clang 12 -gsplit-dwarf implicitly uses -g2.
Fix CONFIG_DEBUG_INFO_SPLIT for gcc-11+ & clang-12+ which now need -g
specified in order for -gsplit-dwarf to work at all.
-gsplit-dwarf has been mutually exclusive with -g since support for
CONFIG_DEBUG_INFO_SPLIT was introduced in
commit 866ced950b ("kbuild: Support split debug info v4")
I don't think it ever needed to be.

io_uring caches task references to avoid doing atomics for each of them
per request. If a request is put from the same task that allocated it,
then we can maintain a per-ctx cache of them. This obviously relies
on io_uring always pruning caches in a reliable way, and there's
currently a case off io_uring fd release where we can miss that.
One example is a ring setup with IOPOLL, which relies on the task
polling for completions, which will free them. However, if such a task
submits a request and then exits or closes the ring without reaping
the completion, then ring release will reap and put. If release happens
from that very same task, the completed request task refs will get
put back into the cache pool. This is problematic, as we're now beyond
the point of pruning caches.
Manually drop these caches after doing an IOPOLL reap. This releases
references from the current task, which is enough. If another task
happens to be doing the release, then the caching will not be
triggered and there's no issue.

Here are two tiny driver core fixes for 6.0-rc7 that resolve some
oft-reported problems.
The first is a revert of the "fw_devlink.strict=1" default option that
we keep trying to enable, but we keep finding platforms that this just
breaks everything on. So again, we need it reverted and hopefully it
can be worked on in future releases.
The second is a sysfs file-size bugfix that resolves an issue that many
people are starting to hit as the fix it is fixing also was backported
to stable kernels. The util-linux developers are starting to get
bugreports about sysfs files that contain no data because of this
problem, and this fix which has been in linux-next in the bitfield tree
for a long time, resolves it. I'm submitting it here as it needs to be
merged for 6.0-final, not for 6.1-rc1.
Both of these have been in linux-next with no reported issues, only
reports were that these fixed problems.

Fix for a code analyser warning
Due to undocumented, hysterical raisins on x86, the CFI jump-table
sections in .text are needlessly aligned to PMD_SIZE in the vmlinux
linker script. When compiling a CFI-enabled arm64 kernel with a 64KiB
page-size, a PMD maps 512MiB of virtual memory and so the .text section
increases to a whopping 940MiB and blows the final Image up to 960MiB.
Others report a link failure.
Since the CFI jump-table requires only instruction alignment, reduce the
alignment directives to function alignment for parity with other parts
of the .text section. This reduces the size of the .text section for the
aforementioned 64KiB page size arm64 kernel to 19MiB for a much more
reasonable total Image size of 39MiB.

Inject #UD when emulating XSETBV if CR4.OSXSAVE is not set. This also
covers the "XSAVE not supported" check, as setting CR4.OSXSAVE=1 #GPs if
XSAVE is not supported (and userspace gets to keep the pieces if it
forces incoherent vCPU state).
Add a comment to kvm_emulate_xsetbv() to call out that the CPU checks
CR4.OSXSAVE before checking for intercepts. AMD'S APM implies that #UD
has priority (says that intercepts are checked before #GP exceptions),
while Intel's SDM says nothing about interception priority. However,
testing on hardware shows that both AMD and Intel CPUs prioritize the #UD
over interception.

Allow FP and SSE state to be saved and restored via KVM_{G,SET}_XSAVE on
XSAVE-capable hosts even if their bits are not exposed to the guest via
XCR0.
Failing to allow FP+SSE first showed up as a QEMU live migration failure,
where migrating a VM from a pre-XSAVE host, e.g. Nehalem, to an XSAVE
host failed due to KVM rejecting KVM_SET_XSAVE. However, the bug also
causes problems even when migrating between XSAVE-capable hosts as
KVM_GET_SAVE won't set any bits in user_xfeatures if XSAVE isn't exposed
to the guest, i.e. KVM will fail to actually migrate FP+SSE.
Because KVM_{G,S}ET_XSAVE are designed to allowing migrating between
hosts with and without XSAVE, KVM_GET_XSAVE on a non-XSAVE (by way of
fpu_copy_guest_fpstate_to_uabi()) always sets the FP+SSE bits in the
header so that KVM_SET_XSAVE will work even if the new host supports
XSAVE.

Reinstate the per-vCPU guest_supported_xcr0 by partially reverting
commit 988896bb6182; the implicit assessment that guest_supported_xcr0 is
always the same as guest_fpu.fpstate->user_xfeatures was incorrect.
kvm_vcpu_after_set_cpuid() isn't the only place that sets user_xfeatures,
as user_xfeatures is set to fpu_user_cfg.default_features when guest_fpu
is allocated via fpu_alloc_guest_fpstate() => __fpstate_reset().
guest_supported_xcr0 on the other hand is zero-allocated. If userspace
never invokes KVM_SET_CPUID2, supported XCR0 will be '0', whereas the
allowed user XFEATURES will be non-zero.
Practically speaking, the edge case likely doesn't matter as no sane
userspace will live migrate a VM without ever doing KVM_SET_CPUID2. The
primary motivation is to prepare for KVM intentionally and explicitly
setting bits in user_xfeatures that are not set in guest_supported_xcr0.
Because KVM_{G,S}ET_XSAVE can be used to svae/restore FP+SSE state even
if the host doesn't support XSAVE, KVM needs to set the FP+SSE bits in
user_xfeatures even if they're not allowed in XCR0, e.g. because XCR0
isn't exposed to the guest. At that point, the simplest fix is to track
the two things separately (allowed save/restore vs. allowed XCR0).

Commit 5a836bf6b0 ("mm: slub: move flush_cpu_slab() invocations
__free_slab() invocations out of IRQ context") moved all flush_cpu_slab()
invocations to the global workqueue to avoid a problem related
with deactivate_slab()/__free_slab() being called from an IRQ context
on PREEMPT_RT kernels.
When the flush_all_cpu_locked() function is called from a task context
it may happen that a workqueue with WQ_MEM_RECLAIM bit set ends up
flushing the global workqueue, this will cause a dependency issue.

A handful of awaited fixes here - revert of the FEC changes,
bluetooth fix, fixes for iwlwifi spew.
We added a warning in PHY/MDIO code which is triggering on
a couple of platforms in a false-positive-ish way. If we can't
iron that out over the week we'll drop it and re-add for 6.1.
I've added a new "follow up fixes" section for fixes to fixes
in 6.0-rcs but it may actually give the false impression that
those are problematic or that more testing time would have
caught them. So likely a one time thing.
Follow up fixes:
- nf_tables_addchain: fix nft_counters_enabled underflow
- ebtables: fix memory leak when blob is malformed
- nf_ct_ftp: fix deadlock when nat rewrite is needed
Current release - regressions:
- Revert "fec: Restart PPS after link state change"
- Revert "net: fec: Use a spinlock to guard `fep->ptp_clk_on`"
- Bluetooth: fix HCIGETDEVINFO regression
- wifi: mt76: fix 5 GHz connection regression on mt76x0/mt76x2
- mptcp: fix fwd memory accounting on coalesce
- rwlock removal fall out:
- ipmr: always call ip{,6}_mr_forward() from RCU read-side

- ipv6: fix crash when IPv6 is administratively disabled
- tcp: read multiple skbs in tcp_read_skb()
- mdio_bus_phy_resume state warning fallout:

Pull networking fixes from Jakub Kicinski:
"Including fixes from wifi, netfilter and can.
A handful of awaited fixes here - revert of the FEC changes, bluetooth
fix, fixes for iwlwifi spew.
We added a warning in PHY/MDIO code which is triggering on a couple of
platforms in a false-positive-ish way. If we can't iron that out over
the week we'll drop it and re-add for 6.1.
I've added a new "follow up fixes" section for fixes to fixes in
6.0-rcs but it may actually give the false impression that those are
problematic or that more testing time would have caught them. So
likely a one time thing.
Follow up fixes:
- nf_tables_addchain: fix nft_counters_enabled underflow
- ebtables: fix memory leak when blob is malformed
- nf_ct_ftp: fix deadlock when nat rewrite is needed
Current release - regressions:
- Revert "fec: Restart PPS after link state change" and the related
"net: fec: Use a spinlock to guard `fep->ptp_clk_on`"
- Bluetooth: fix HCIGETDEVINFO regression
- wifi: mt76: fix 5 GHz connection regression on mt76x0/mt76x2
- mptcp: fix fwd memory accounting on coalesce
- rwlock removal fall out:
- ipmr: always call ip{,6}_mr_forward() from RCU read-side

- ipv6: fix crash when IPv6 is administratively disabled
- tcp: read multiple skbs in tcp_read_skb()
- mdio_bus_phy_resume state warning fallout:

Current release - new code bugs:
- wifi: iwlwifi: don't spam logs with NSS>2 messages
- eth: mtk_eth_soc: enable XDP support just for MT7986 SoC
Previous releases - regressions:
- bonding: fix NULL deref in bond_rr_gen_slave_id
- wifi: iwlwifi: mark IWLMEI as broken
Previous releases - always broken:
- nf_conntrack helpers:
- irc: tighten matching on DCC message

This patch avoids threads live-locking for hours when a large number
threads are competing over the last few free extents as they blocks
getting added and removed from preallocation pools. From our bug
reporter:
A reliable way for triggering this has multiple writers
continuously write() to files when the filesystem is full, while
small amounts of space are freed (e.g. by truncating a large file
-1MiB at a time). In the local filesystem, this can be done by
simply not checking the return code of write (0) and/or the error
(ENOSPACE) that is set. Over NFS with an async mount, even clients
with proper error checking will behave this way since the linux NFS
client implementation will not propagate the server errors [the
write syscalls immediately return success] until the file handle is
closed. This leads to a situation where NFS clients send a
continuous stream of WRITE rpcs which result in ERRNOSPACE -- but
since the client isn't seeing this, the stream of writes continues
at maximum network speed.
When some space does appear, multiple writers will all attempt to
claim it for their current write. For NFS, we may see dozens to
hundreds of threads that do this.
The real-world scenario of this is database backup tooling (in
particular, github.com/mdkent/percona-xtrabackup) which may write
large files (>1TiB) to NFS for safe keeping. Some temporary files
are written, rewound, and read back -- all before closing the file
handle (the temp file is actually unlinked, to trigger automatic
deletion on close/crash.) An application like this operating on an
async NFS mount will not see an error code until TiB have been
written/read.
The lockup was observed when running this database backup on large
filesystems (64 TiB in this case) with a high number of block
groups and no free space. Fragmentation is generally not a factor
in this filesystem (~thousands of large files, mostly contiguous
except for the parts written while the filesystem is at capacity.)

When the PWM driver was changed to disable clocks if no PWMs are enabled,
it ended up also disabling the shared parent with the UART, since the
UART doesn't do any clock enablement on its own.

When reading the timestamp is required bnxt_tx_int() hands
over the ownership of the completed skb to the PTP worker.
The skb should not be used afterwards, as the worker may
run before the rest of our code and free the skb, leading
to a use-after-free.
Since dev_kfree_skb_any() accepts NULL make the loss of
ownership more obvious and set skb to NULL.

There is a separate receive path for small packets (under 256 bytes).
Instead of allocating a new dma-capable skb to be used for the next packet,
this path allocates a skb and copies the data into it (reusing the existing
sbk for the next packet). There are two bytes of junk data at the beginning
of every packet. I believe these are inserted in order to allow aligned DMA
and IP headers. We skip over them using skb_reserve. Before copying over
the data, we must use a barrier to ensure we see the whole packet. The
current code only synchronizes len bytes, starting from the beginning of
the packet, including the junk bytes. However, this leaves off the final
two bytes in the packet. Synchronize the whole packet.
To reproduce this problem, ping a HME with a payload size between 17 and
214
$ ping -s 17 <hme_address>
which will complain rather loudly about the data mismatch. Small packets
(below 60 bytes on the wire) do not have this issue. I suspect this is
related to the padding added to increase the minimum packet size.
