The lpfc_sli4_nvmet_xri_aborted() routine takes out the abts_buf_list_lock
and traverses the buffer contexts to match the xri. Upon match, it then
takes the context lock before potentially removing the context from the
associated buffer list. This violates the lock hierarchy used elsewhere in
the driver of locking context, then the abts_buf_list_lock - thus a
possible deadlock.
Resolve by: after matching, release the abts_buf_list_lock, then take the
context lock, and if to be deleted from the list, retake the
abts_buf_list_lock, maintaining lock hierarchy. This matches same list lock
hierarchy as elsewhere in the driver

cdrom_read_cdda_bpc() relies on sending SCSI command to the low level
driver using a REQ_OP_SCSI_IN request. This isn't generic block layer
functionality, so move the actual low-level code into the sr driver and
call it through a new read_cdda_bpc method in the cdrom_device_ops

With this the CDROM code does not have to pull in scsi_normalize_sense()
and depend on CONFIG_SCSI_COMMON.

Q1 and Q2 are numbers with *maximum* length of 384 bytes. If the
calculated length of Q1 and Q2 is less than 384 bytes, things will
go wrong.
E.g. if Q2 is 383 bytes, then
1. The bytes of q2 are copied to sigstruct->q2 in calc_q1q2().
2. The entire sigstruct->q2 is reversed, which results it being
256 * Q2, given that the last byte of sigstruct->q2 is added
to before the bytes given by calc_q1q2().
Either change in key or measurement can trigger the bug. E.g. an
unmeasured heap could cause a devastating change in Q1 or Q2.
Reverse exactly the bytes of Q1 and Q2 in calc_q1q2() before returning
to the caller.

Since commit 1b6b26ae70 ("pipe: fix and clarify pipe write wakeup
logic") we have sanitized the pipe write logic, and would only try to
wake up readers if they needed it.
In particular, if the pipe already had data in it before the write,
there was no point in trying to wake up a reader, since any existing
readers must have been aware of the pre-existing data already. Doing
extraneous wakeups will only cause potential thundering herd problems.
However, it turns out that some Android libraries have misused the EPOLL
interface, and expected "edge triggered" be to "any new write will
trigger it". Even if there was no edge in sight.
Quoting Sandeep Patil:
"The commit 1b6b26ae70 ('pipe: fix and clarify pipe write wakeup
logic') changed pipe write logic to wakeup readers only if the pipe
was empty at the time of write. However, there are libraries that
relied upon the older behavior for notification scheme similar to
what's described in [1]
One such library 'realm-core'[2] is used by numerous Android
applications. The library uses a similar notification mechanism as GNU
Make but it never drains the pipe until it is full. When Android moved
to v5.10 kernel, all applications using this library stopped working.
The library has since been fixed[3] but it will be a while before all
applications incorporate the updated library"
Our regression rule for the kernel is that if applications break from
new behavior, it's a regression, even if it was because the application
did something patently wrong. Also note the original report [4] by
Michal Kerrisk about a test for this epoll behavior - but at that point
we didn't know of any actual broken use case.
So add the extraneous wakeup, to approximate the old behavior.
[ I say "approximate", because the exact old behavior was to do a wakeup
not for each write(), but for each pipe buffer chunk that was filled
in. The behavior introduced by this change is not that - this is just
"every write will cause a wakeup, whether necessary or not", which
seems to be sufficient for the broken library use. ]
It's worth noting that this adds the extraneous wakeup only for the
write side, while the read side still considers the "edge" to be purely
about reading enough from the pipe to allow further writes.
See commit f467a6a664 ("pipe: fix and clarify pipe read wakeup logic")
for the pipe read case, which remains that "only wake up if the pipe was
full, and we read something from it".

====================
To work with the different program types, map types, attach types etc.
supported by eBPF, bpftool needs occasional updates to learn about the new
features supported by the kernel. When such types translate into new
keyword for the command line, updates are expected in several locations:
typically, the help message displayed from bpftool itself, the manual page,
and the bash completion file should be updated. The options used by the
different commands for bpftool should also remain synchronised at those
locations.
Several omissions have occurred in the past, and a number of types are
still missing today. This set is an attempt to improve the situation. It
brings up-to-date the lists of types or options in bpftool, and also adds a
Python script to the BPF selftests to automatically check that most of
these lists remain synchronised.
v2:
- Reformat some lines in the bash completion file.
- Do not reformat attach types, to preserve git-blame history.
- Do not call Python script from tools/testing/selftests/bpf/Makefile.

All bpftool commands support the options for JSON output and debug from
libbpf. In addition, some commands support additional options
corresponding to specific use cases.
The list of options described in the man pages for the different
commands are not always accurate. The messages for interactive help are
mostly limited to HELP_SPEC_OPTIONS, and are even less representative of
the actual set of options supported for the commands.
Let's update the lists:
- HELP_SPEC_OPTIONS is modified to contain the "default" options (JSON
and debug), and to be extensible (no ending curly bracket).
- All commands use HELP_SPEC_OPTIONS in their help message, and then
complete the list with their specific options.
- The lists of options in the man pages are updated.
- The formatting of the list for bpftool.rst is adjusted to match
formatting for the other man pages. This is for consistency, and also
because it will be helpful in a future patch to automatically check
that the files are synchronised.

Whenever the eBPF subsystem gains new elements, such as new program or
map types, it is necessary to update bpftool if we want it able to
handle the new items.
In addition to the main arrays containing the names of these elements in
the source code, there are also multiple locations to update:
- The help message in the do_help() functions in bpftool's source code.
- The RST documentation files.
- The bash completion file.
This has led to omissions multiple times in the past. This patch
attempts to address this issue by adding consistency checks for all
these different locations. It also verifies that the bpf_prog_type,
bpf_map_type and bpf_attach_type enums from the UAPI BPF header have all
their members present in bpftool.
The script requires no argument to run, it reads and parses the
different files to check, and prints the mismatches, if any. It
currently reports a number of missing elements, which will be fixed in a
later patch:
$ ./test_bpftool_synctypes.py

Comparing [...]/linux/tools/bpf/bpftool/prog.c (attach_type_strings) and [...]/linux/tools/bpf/bpftool/bash-completion/bpftool (BPFTOOL_PROG_ATTACH_TYPES): {'skb_verdict'}
Note that the script does NOT check for consistency between the list of
program types that bpftool claims it accepts and the actual list of
keywords that can be used. This is because bpftool does not "see" them,
they are ELF section names parsed by libbpf. It is not hard to parse the
section_defs[] array in libbpf, but some section names are associated
with program types that bpftool cannot load at the moment. For example,
some programs require a BTF target and an attach target that bpftool
cannot handle. The script may be extended to parse the array and check
only relevant values in the future.
The script is not added to the selftests' Makefile, because doing so
would require all patches with BPF UAPI change to also update bpftool.
Instead it is to be added to the CI.

Bash completion for bpftool gets two minor improvements in this patch.
Move the detection of attach types for "bpftool cgroup attach" outside
of the "case/esac" bloc, where we cannot reuse our variable holding the
list of supported attach types as a pattern list. After the change, we
have only one list of cgroup attach types to update when new types are
added, instead of the former two lists.
Also rename the variables holding lists of names for program types, map
types, and attach types, to make them more unique. This can make it
slightly easier to point people to the relevant variables to update, but
the main objective here is to help run a script to check that bash
completion is up-to-date with bpftool's source code.

There is no need in extra call indirection and check from impossible
flow where someone tries to set namespace without prior call
to devlink_alloc().
Instead of this extra logic and additional EXPORT_SYMBOL, use specialized
devlink allocation function that receives net namespace as an argument.
Such specialized API allows clear view when devlink initialized in wrong
net namespace and/or kernel users don't try to change devlink namespace
under the hood.
