When execute command "perf lock report", it hits failure and outputs log
as follows:
perf: builtin-lock.c:623: report_lock_release_event: Assertion `!(seq->read_count < 0)' failed.
Aborted
This is an imbalance issue. The locking sequence structure
"lock_seq_stat" contains the reader counter and it is used to check if
the locking sequence is balance or not between acquiring and releasing.
If the tool wrongly frees "lock_seq_stat" when "read_count" isn't zero,
the "read_count" will be reset to zero when allocate a new structure at
the next time; thus it causes the wrong counting for reader and finally
results in imbalance issue.
To fix this issue, if detects "read_count" is not zero (means still have
read user in the locking sequence), goto the "end" tag to skip freeing
structure "lock_seq_stat".

The tracepoint "lock:lock_acquire" contains field "flags" but not
"flag". Current code wrongly retrieves value from field "flag" and it
always gets zero for the value, thus "perf lock" doesn't report the
correct result.
This patch replaces the field name "flag" with "flags", so can read out
the correct flags for locking.

Here's my proposal to fix the use-after-free bugs reported by
Sascha Hauer and Florian Fainelli:
I scrutinized all SPI drivers in the v5.10 tree:
* There are 9 drivers with a use-after-free in the ->remove() hook
caused by accessing driver private data after spi_unregister_controller().
* There are 8 drivers which leak the spi_controller in the ->probe()
error path because of a missing spi_controller_put().
I'm introducing devm_spi_alloc_master/slave() which automatically
calls spi_controller_put() on ->remove(). This fixes both classes
of bugs while at the same time reducing code amount and complexity
in the ->probe() hook.
I propose that spi_controller_unregister() should no longer release
a reference on the spi_controller. Instead, drivers need to either
do it themselves or use one of the devm functions introduced herein.
The vast majority of drivers can be converted to the devm functions.
See the commit message of patch [1/4] for the rationale and details.
Enclosed are patches for 3 Broadcom drivers.
Patches for the other drivers are on this branch:
https://github.com/l1k/linux/commits/spi_fixes
@Florian Fainelli: Could you verify that there are no KASAN splats or
leaks with these patches? Unfortunately I do not have any SPI-capable
hardware at my disposal right now, so can only compile-test. You may
want to augment spi_controller_release() with a printk() to log when
the spi_controller is freed.
@Mark Brown: Patches [2/4] to [4/4] reference the SHA-1 of patch [1/4]
in their stable tags. Because the hash is unknown to me until you apply
the patch, I've used "123456789abc" as a placeholder. You'll have to
replace the hash if/when applying. Alternatively, only apply patch [1/4]
and I'll repost the other patches with the hash fixed up.
Thanks!

Normally the last reference on an spi_controller is released by
spi_unregister_controller(). In the case of the i.MX lpspi driver,
the spi_controller is registered with devm_spi_register_controller(),
so spi_unregister_controller() is invoked automatically after the driver
has unbound.
However the driver already releases the last reference in
fsl_lpspi_remove() through a gratuitous call to spi_master_put(),
causing a use-after-free when spi_unregister_controller() is
subsequently invoked by the devres framework.
Fix by dropping the superfluous spi_master_put().

Alexander Lobakin says:
====================
net: udp: fix Fast/frag0 UDP GRO
While testing UDP GSO fraglists forwarding through driver that uses
Fast GRO (via napi_gro_frags()), I was observing lots of out-of-order
iperf packets:
[ ID] Interval Transfer Bitrate Jitter
[SUM] 0.0-40.0 sec 12106 datagrams received out-of-order
Simple switch to napi_gro_receive() or any other method without frag0
shortcut completely resolved them.
I've found two incorrect header accesses in GRO receive callback(s):
- udp_hdr() (instead of udp_gro_udphdr()) that always points to junk
in "fast" mode and could probably do this in "regular".
This was the actual bug that caused all out-of-order delivers;
- udp{4,6}_lib_lookup_skb() -> ip{,v6}_hdr() (instead of
skb_gro_network_header()) that potentionally might return odd
pointers in both modes.
Each patch addresses one of these two issues.
This doesn't cover a support for nested tunnels as it's out of the
subject and requires more invasive changes. It will be handled
separately in net-next series.

Since v4 [0]:
- split the fix into two logical ones (Willem);
- replace ternaries with plain ifs to beautify the code (Jakub);
- drop p->data part to reintroduce it later in abovementioned set.
Since v3 [1]:
- restore the original {,__}udp{4,6}_lib_lookup_skb() and use
private versions of them inside GRO code (Willem).
Since v2 [2]:
- dropped redundant check introduced in v2 as it's performed right
before (thanks to Eric);
- udp_hdr() switched to data + off for skbs from list (also Eric);
- fixed possible malfunction of {,__}udp{4,6}_lib_lookup_skb() with
Fast/frag0 due to ip{,v6}_hdr() usage (Willem).
Since v1 [3]:
- added a NULL pointer check for "uh" as suggested by Willem.

udp{4,6}_lib_lookup_skb() use ip{,v6}_hdr() to get IP header of the
packet. While it's probably OK for non-frag0 paths, this helpers
will also point to junk on Fast/frag0 GRO when all headers are
located in frags. As a result, sk/skb lookup may fail or give wrong
results. To support both GRO modes, skb_gro_network_header() might
be used. To not modify original functions, add private versions of
udp{4,6}_lib_lookup_skb() only to perform correct sk lookups on GRO.
Present since the introduction of "application-level" UDP GRO
in 4.7-rc1.
Misc: replace totally unneeded ternaries with plain ifs.

UDP GRO uses udp_hdr(skb) in its .gro_receive() callback. While it's
probably OK for non-frag0 paths (when all headers or even the entire
frame are already in skb head), this inline points to junk when
using Fast GRO (napi_gro_frags() or napi_gro_receive() with only
Ethernet header in skb head and all the rest in the frags) and breaks
GRO packet compilation and the packet flow itself.
To support both modes, skb_gro_header_fast() + skb_gro_header_slow()
are typically used. UDP even has an inline helper that makes use of
them, udp_gro_udphdr(). Use that instead of troublemaking udp_hdr()
to get rid of the out-of-order delivers.
Present since the introduction of plain UDP GRO in 5.0-rc1.

Patch b2a846dbef4e ("gfs2: Ignore journal log writes for jdata holes")
tried (unsuccessfully) to fix a case in which writes were done to jdata
blocks, the blocks are sent to the ail list, then a punch_hole or truncate
operation caused the blocks to be freed. In other words, the ail items
are for jdata holes. Before b2a846dbef4e, the jdata hole caused function
gfs2_block_map to return -EIO, which was eventually interpreted as an
IO error to the journal, and then withdraw.
This patch changes function gfs2_get_block_noalloc, which is only used
for jdata writes, so it returns -ENODATA rather than -EIO, and when
-ENODATA is returned to gfs2_ail1_start_one, the error is ignored.
We can safely ignore it because gfs2_ail1_start_one is only called
when the jdata pages have already been written and truncated, so the
ail1 content no longer applies.

This reverts commit b2a846dbef4ef54ef032f0f5ee188c609a0278a7.
That commit changed the behavior of function gfs2_block_map to return
-ENODATA in cases where a hole (IOMAP_HOLE) is encountered and create is
false. While that fixed the intended problem for jdata, it also broke
other callers of gfs2_block_map such as some jdata block reads. Before
the patch, an encountered hole would be skipped and the buffer seen as
unmapped by the caller. The patch changed the behavior to return
-ENODATA, which is interpreted as an error by the caller.
The -ENODATA return code should be restricted to the specific case where
jdata holes are encountered during ail1 writes. That will be done in a
later patch.

SND_INTEL_DSP_CONFIG is selected by the HDaudio, Skylake and SOF
drivers. When the HDaudio link is not selected as a option, this
Kconfig option is not touched and will default to whatever other
drivers selected. In the case e.g. where HDaudio is compiled as
built-in, the linker will complain:
ld: sound/soc/sof/sof-pci-dev.o: in function `sof_pci_probe':
sof-pci-dev.c:(.text+0x5c): undefined reference to
`snd_intel_dsp_driver_probe'
Adding the select for all HDaudio platforms, regardless of whether
they rely on the HDaudio link or not, solves the problem.

The xarray is never mutated from an IRQ handler, only from work queues
under a spinlock_irq. Thus there is no reason for it be an IRQ type
xarray.
This was copied over from the original IDR code, but the recent rework put
the xarray inside another spinlock_irq which will unbalance the unlocking.

VRF devices use an optimized direct path on output if a default qdisc
is involved, calling Netfilter hooks directly. This path, however, does
not consider Netfilter rules completing asynchronously, such as with
NFQUEUE. The Netfilter okfn() is called for asynchronously accepted
packets, but the VRF never passes that packet down the stack to send
it out over the slave device. Using the slower redirect path for this
seems not feasible, as we do not know beforehand if a Netfilter hook
has asynchronously completing rules.
Fix the use of asynchronously completing Netfilter rules in OUTPUT and
POSTROUTING by using a special completion function that additionally
calls dst_output() to pass the packet down the stack. Also, slightly
adjust the use of nf_reset_ct() so that is called in the asynchronous
case, too.

Certain NFSv4.2/RDMA tests fail with v5.9-rc1.
rpcrdma_convert_kvec() runs off the end of the rl_segments array
because rq_rcv_buf.tail[0].iov_len holds a very large positive
value. The resultant kernel memory corruption is enough to crash
the client system.
Callers of rpc_prepare_reply_pages() must reserve an extra XDR_UNIT
in the maximum decode size for a possible XDR pad of the contents
of the xdr_buf's pages. That guarantees the allocated receive buffer
will be large enough to accommodate the usual contents plus that XDR
pad word.
encode_op_hdr() cannot add that extra word. If it does,
xdr_inline_pages() underruns the length of the tail iovec.

We forgot to unregister the nfs4_xattr_large_entry_shrinker.
That leaves the global list of shrinkers corrupted after unload of the
nfs module, after which possibly unrelated code that calls
register_shrinker() or unregister_shrinker() gets a BUG() with
"supervisor write access in kernel mode".
And similarly for the nfs4_xattr_large_entry_lru.

The firmware extended data IPC and manifest structures are designed to
be extendable without breaking the driver-firmware ABI. Driver should
not raise a warning in case a new header type is detected at
firmware boot. There are already checks for IPC ABI compatibility in
snd_sof_ipc_valid() and if the versions are deemed compatible, extra
fields in IPC messages should not trigger warnings.

bcm_qspi_remove() calls spi_unregister_master() even though
bcm_qspi_probe() calls devm_spi_register_master(). The spi_master is
therefore unregistered and freed twice on unbind.
Moreover, since commit 0392727c261b ("spi: bcm-qspi: Handle clock probe
deferral"), bcm_qspi_probe() leaks the spi_master allocation if the call
to devm_clk_get_optional() fails.
Fix by switching over to the new devm_spi_alloc_master() helper which
keeps the private data accessible until the driver has unbound and also
avoids the spi_master leak on probe.
While at it, fix an ordering issue in bcm_qspi_remove() wherein
spi_unregister_master() is called after uninitializing the hardware,
disabling the clock and freeing an IRQ data structure. The correct
order is to call spi_unregister_master() *before* those teardown steps
because bus accesses may still be ongoing until that function returns.
