commit 700c1018b86d0d4b3f1f2d459708c0cdf42b521d upstream.
gawk 5.0.1 generates the following regexp warnings:
GEN /home/sasha/torvalds/tools/objtool/arch/x86/lib/inat-tables.c
awk: ../arch/x86/tools/gen-insn-attr-x86.awk:260: warning: regexp escape sequence `\:' is not a known regexp operator
awk: ../arch/x86/tools/gen-insn-attr-x86.awk:350: (FILENAME=../arch/x86/lib/x86-opcode-map.txt FNR=41) warning: regexp escape sequence `\&' is not a known regexp operator
Ealier versions of gawk are not known to generate these warnings. The
gawk manual referenced below does not list characters ':' and '&' as
needing escaping, so 'unescape' them. See
https://www.gnu.org/software/gawk/manual/html_node/Escape-Sequences.html
for more info.
Running diff on the output generated by the script before and after
applying the patch reported no differences.

[ Upstream commit f120919f9905a2cad9dea792a28a11fb623f72c1 ]
Function open_obj_pinned() prints error messages when it fails to open a
link in the BPF virtual file system. However, in some occasions it is
not desirable to print an error, for example when we parse all links
under the bpffs root, and the error is due to some paths actually being
symbolic links.
Example output:
# ls -l /sys/fs/bpf/
lrwxrwxrwx 1 root root 0 Oct 18 19:00 ip -> /sys/fs/bpf/tc/
drwx------ 3 root root 0 Oct 18 19:00 tc
lrwxrwxrwx 1 root root 0 Oct 18 19:00 xdp -> /sys/fs/bpf/tc/
# bpftool --bpffs prog show
Error: bpf obj get (/sys/fs/bpf): Permission denied
Error: bpf obj get (/sys/fs/bpf): Permission denied
# strace -e bpf bpftool --bpffs prog show
bpf(BPF_OBJ_GET, {pathname="/sys/fs/bpf/ip", bpf_fd=0}, 72) = -1 EACCES (Permission denied)
Error: bpf obj get (/sys/fs/bpf): Permission denied
bpf(BPF_OBJ_GET, {pathname="/sys/fs/bpf/xdp", bpf_fd=0}, 72) = -1 EACCES (Permission denied)
Error: bpf obj get (/sys/fs/bpf): Permission denied
...
To fix it, pass a bool as a second argument to the function, and prevent
it from printing an error when the argument is set to true.

[ Upstream commit 3404155190ce09a1e5d8407e968fc19aac4493e3 ]
turbostat recently gained a feature adding APIC and X2APIC columns.
While they are disabled by-default, they are enabled with --debug
or when explicitly requested, eg.
$ sudo turbostat --quiet --show Package,Node,Core,CPU,APIC,X2APIC date
But these columns erroneously showed zeros on AMD hardware.
This patch corrects the APIC and X2APIC [sic] columns on AMD.

[ Upstream commit e325808c0051b16729ffd472ff887c6cae5c6317 ]
Currently the call to atoi is being passed a single char string
that is not null terminated, so there is a potential read overrun
along the stack when parsing for an integer value. Fix this by
instead using a 2 char string that is initialized to all zeros
to ensure that a 1 char read into the string is always terminated
with a \0.
Detected by cppcheck:
"Invalid atoi() argument nr 1. A nul-terminated string is required."

[ Upstream commit 372809055f6c830ff978564e09f58bcb9e9b937c ]
Immediately after mlxsw module is probed and lldpad started, added APP
entries are briefly in "unknown" state before becoming "pending". That's
the state that lldpad_app_wait_set() typically sees, and since there are
no pending entries at that time, it bails out. However the entries have
not been pushed to the kernel yet at that point, and thus the test case
fails.
Fix by waiting for both unknown and pending entries to disappear before
proceeding.

commit 5c089fd0c73411f2170ab795c9ffc16718c7d007 upstream.
If the entry is deleted from the IDR between the call to
radix_tree_iter_find() and rcu_dereference_raw(), idr_get_next()
will return NULL, which will end the iteration prematurely. We should
instead continue to the next entry in the IDR. This only happens if the
iteration is protected by the RCU lock. Most IDR users use a spinlock
or semaphore to exclude simultaneous modifications. It was noticed once
the PID allocator was converted to use the IDR, as it uses the RCU lock,
but there may be other users elsewhere in the kernel.
We can't use the normal pattern of calling radix_tree_deref_retry()
(which catches both a retry entry in a leaf node and a node entry in
the root) as the IDR supports storing entries which are unaligned,
which will trigger an infinite loop if they are encountered. Instead,
we have to explicitly check whether the entry is a retry entry.

[ Upstream commit 44d947eff19d64384efc06069509db7a0a1103b0 ]
There are cases where the test is not expecting to have the transaction
aborted, but, the test process might have been rescheduled, either in the
OS level or by KVM (if it is running on a KVM guest machine). The process
reschedule will cause a treclaim/recheckpoint which will cause the
transaction to doom, aborting the transaction as soon as the process is
rescheduled back to the CPU. This might cause the test to fail, but this is
not a failure in essence.
If that is the case, TEXASR[FC] is indicated with either
TM_CAUSE_RESCHEDULE or TM_CAUSE_KVM_RESCHEDULE for KVM interruptions.
In this scenario, ignore these two failures and avoid the whole test to
return failure.

commit 4a6a6f5c4aeedb72db871d60bfcca89835f317aa upstream.
make TARGETS=gpio kselftest fails with:
Makefile:23: tools/build/Makefile.include: No such file or directory
When the gpio tool make is invoked from tools Makefile, srctree is
cleared and the current logic check for srctree equals to empty
string to determine srctree location from CURDIR.
When the build in invoked from selftests/gpio Makefile, the srctree
is set to "." and the same logic used for srctree equals to empty is
needed to determine srctree.
Check building_out_of_srctree undefined as the condition for both
cases to fix "make TARGETS=gpio kselftest" build failure.

commit 5b216ea1c40cf06eead15054c70e238c9bd4729e upstream.
Newer versions of GCC (>= 9) demand that the size of the string to be
copied must be explicitly smaller than the size of the destination.
Thus, the NULL char has to be taken into account on strncpy.
This will avoid the following compiling error:
tlbie_test.c: In function 'main':
tlbie_test.c:639:4: error: 'strncpy' specified bound 100 equals destination size
strncpy(logdir, optarg, LOGDIR_NAME_SIZE);

[ Upstream commit d64479a3e3f9924074ca7b50bd72fa5211dca9c1 ]
This test reports EINVAL for getsockopt(SOL_SOCKET, SO_DOMAIN)
occasionally due to the uninitialized length parameter.
Initialize it to fix this, and also use int for "test_family" to comply
with the API standard.

The memory @orig_flags is allocated by strdup(), it is freed on the

Fix this by adding free(orig_flags) on the error path.

[ Upstream commit 211f493b611eef012841f795166c38ec7528738d ]
We were just returning -1 in symbol__annotate() when symbol__annotate()
failed, propagate its error as it is used later to pass to
symbol__strerror_disassemble() to present a error message to the user,
that in some cases were getting:
"Invalid -1 error code"
Fix it to propagate the error.

[ Upstream commit a66fa0619a0ae3585ef09e9c33ecfb5c7c6cb72b ]
The callers of symbol__annotate2() use symbol__strerror_disassemble() to
convert its failure returns into a human readable string, so
propagate error values from functions it calls, starting with
perf_env__arch() that when fails the right thing to do is to look at
'errno' to see why its possible call to uname() failed.

[ Upstream commit 6bdfd9f118bd59cf0f85d3bf4b72b586adea17c1 ]
The Intel fixed counters use a special table to override the JSON
information.
During this override the period information from the JSON file got
dropped, which results in inst_retired.any and similar running with
frequency mode instead of a period.
Just specify the expected period in the table.
