New features like the BPF --filter support in perf record have made the
BPF event functionality somewhat redundant. As shown by commit
fcb027c1a4f6 ("perf tools: Revert enable indices setting syntax for BPF
map") and commit 14e4b9f428 ("perf trace: Raw augmented syscalls fix
libbpf 1.0+ compatibility") the BPF event support hasn't been well
maintained and it adds considerable complexity in areas like event
parsing, not least as '/' is a separator for event modifiers as well as
in paths.
This patch removes support in the event parser for BPF events and then
the associated functions are removed. This leads to the removal of whole
source files like bpf-loader.c. Removing support means that augmented
syscalls in perf trace is broken, this will be fixed in a later commit
adding support using BPF skeletons.
The removal of BPF events causes an unused label warning from flex
generated code, so update build to ignore it:
```
util/parse-events-flex.c:2704:1: error: label ‘find_rule’ defined but not used [-Werror=unused-label]
2704 | find_rule: /* we branch to this label when backing up */
```
Committer notes:
Extracted from a larger patch that was also removing the support for
linking with libllvm and libclang, that were an alternative to using an
external clang execution to compile the .c event source code into BPF
bytecode.
Testing it:
# perf trace -e /home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.c
event syntax error: '/home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.c'
\___ Bad event or PMU

Initial error:

\___ Cannot find PMU `home'. Missing kernel support?

With augmented_raw_syscalls transformed into a BPF skel made the output have a "
around the filenames, which is not what the old perf probe vfs_getname
method of obtaining filenames did, so accept the augmented way, with the
quotes.
At this point probably removing all the logic for the vfs_getname method
is in order, will do it at some point.
For now lets accept with/without quotes and make that test pass.

In the real workload, I encountered an issue which could cause the RTO
timer to retransmit the skb per 1ms with linear option enabled. The amount
of lost-retransmitted skbs can go up to 1000+ instantly.
The root cause is that if the icsk_rto happens to be zero in the 6th round
(which is the TCP_THIN_LINEAR_RETRIES value), then it will always be zero
due to the changed calculation method in tcp_retransmit_timer() as follows:
icsk->icsk_rto = min(icsk->icsk_rto << 1, TCP_RTO_MAX);
Above line could be converted to
icsk->icsk_rto = min(0 << 1, TCP_RTO_MAX) = 0
Therefore, the timer expires so quickly without any doubt.
I read through the RFC 6298 and found that the RTO value can be rounded
up to a certain value, in Linux, say TCP_RTO_MIN as default, which is
regarded as the lower bound in this patch as suggested by Eric.

Before adding a new FW control, its name is checked against
existing controls list. But the string length in strncmp used
to compare controls names is taken from the list, so if beginnings
of the controls are matching, then the new control is not created.
For example, if CAL_R control already exists, CAL_R_SELECTED
is not created.
The fix is to compare string lengths as well.

'type' is an enum, thus cast of pointer on 64-bit compile test with W=1
causes:

Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:
Use the FIRMWARE_MISSING flag in the CS35L56 to determine whether it is
safe to download a firmware patch.
Merge series from Li Zetao <lizetao1@huawei.com>:
This patch set use the helper function devm_kmemdup() to replace
devm_kmalloc + memcpy, which is the same as implementing the function
separately.
Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
The use of the widget name as a prefix for the kcontrol name is quite
useful in the case of multiple pipelines going to the same endpoint,
but it's overkill in simpler cases.
This patchset extends the existing DAPM code to drop the widget name
prefix and make the kcontrol names simpler when there's no possible
ambiguity, e.g. "gain.2.1 Main Playback Volume" becomes just "Main
Playback Volume".
Fix copy-paste error in MODULE_DEVICE_TABLE() for the OF table,
use the 'of' first parameter instead of duplicate 'i2c'.

r5l_flush_stripe_to_raid() will check if the list 'flushing_ios' is
empty, and then submit 'flush_bio', however, r5l_log_flush_endio()
is clearing the list first and then clear the bio, which will cause
null-ptr-deref:
T1: submit flush io
raid5d
handle_active_stripes
r5l_flush_stripe_to_raid
// list is empty
// add 'io_end_ios' to the list
bio_init
submit_bio
// io1
T2: io1 is done
r5l_log_flush_endio
list_splice_tail_init
// clear the list
T3: submit new flush io
...
r5l_flush_stripe_to_raid
// list is empty
// add 'io_end_ios' to the list
bio_init
bio_uninit
// clear bio->bi_blkg
submit_bio
// null-ptr-deref
Fix this problem by clearing bio before clearing the list in
r5l_log_flush_endio().

Altivec is only available for powerpc hosts, so only check for its
availability when the host is powerpc, to avoid error messages being
shown on architectures other than x86, arm or powerpc.

Currently when the raid6test utility is built, the resulting binary and
an int.uc file are not being ignored, which can get inadvertently
committed as a result when one works on the raid6 code. Ignore them to
make `git status` clean at all times.

Use tabs/spaces consistently: hard tabs for marking recipe lines only,
spaces for everything else.
Also, the OPTFLAGS declaration actually included the tabs preceding the
line comment, making compiler invocation lines unnecessarily long. As
the entire block of declarations are meant for ad-hoc customization
(otherwise they would probably make use of `?=` instead of `=`), move
the "Adjust as desired" comment above the block too to fix the long
invocation lines.

After commit b39f35ebe8 ("md: don't quiesce in mddev_suspend()"),
'conf->barrier' will be leaked in the case that raid10 takeover raid0:
level_store
pers->takeover -> raid10_takeover
raid10_takeover_raid0
WRITE_ONCE(conf->barrier, 1)
mddev_suspend
// still raid0
mddev->pers = pers
// switch to raid10
mddev_resume
// resume without suspend
After the above commit, mddev_resume() will not decrease 'conf->barrier'
that is set in raid10_takeover_raid0().
Fix this problem by not setting 'conf->barrier' in raid10_takeover_raid0().
By the way, this problem is found while I'm trying to make
mddev_suspend/resume() to be independent from raid personalities. raid10
is the only personality to use reference count in the quiesce() callback
and this problem is only related to raid10.

Commit b13015af94 ("md/raid5-cache: Clear conf->log after finishing
work") introduce a new problem:
// caller hold reconfig_mutex
r5l_exit_log
flush_work(&log->disable_writeback_work)
r5c_disable_writeback_async
wait_event
/*
* conf->log is not NULL, and mddev_trylock()
* will fail, wait_event() can never pass.
*/
conf->log = NULL
Fix this problem by setting 'config->log' to NULL before wake_up() as it
used to be, so that wait_event() from r5c_disable_writeback_async() can
exist. In the meantime, move forward md_unregister_thread() so that
null-ptr-deref this commit fixed can still be fixed.
