fc73ded13f perf arm-spe: Fix endless record after being terminated
commit d6bc34c5ec upstream.

In __cmd_record(), when receiving SIGINT(ctrl + c), a 'done' flag will
be set and the event list will be disabled by evlist__disable() once.

While in auxtrace_record.read_finish(), the related events will be
enabled again, if they are continuous, the recording seems to be
endless.

If the event is disabled, don't enable it again here.

be set and the event list will be disabled by evlist__disable() once.

Note: This patch is NOT tested since i don't have such a machine with
coresight feature, but the code seems buggy same as arm-spe and
intel-pt.

Tester notes:

Thanks for looping, Adrian.  Applied this patch and tested with
CoreSight on juno board, it works well.

0x11 and 0x12 set the ECN bits based on RFC2474, it would be better to avoid
that. 0x14 and 0x18 would be better and works as well.

[ Upstream commit 4e867c9a50 ]

After commit 71130f2997 ("vxlan: fix tos value before xmit") we start
strict vxlan xmit tos value by RT_TOS(), which limits the tos value less
than 0x1E. With current value 0x40 the test will failed with "v1: Expected
to capture 10 packets, got 0". So let's choose a smaller tos value for
testing.

5c0f7f2097 selftests: forwarding: use proto icmp for {gretap, ip6gretap}_mac testing
[ Upstream commit e8023b030c ]

For tc ip_proto filter, when we extract the flow via __skb_flow_dissect()
without flag FLOW_DISSECTOR_F_STOP_AT_ENCAP, we will continue extract to
the inner proto.

So for GRE + ICMP messages, we should not track GRE proto, but inner ICMP
proto.

For test mirror_gre.sh, it may make user confused if we capture ICMP
message on $h3(since the flow is GRE message). So I move the capture
dev to h3-gt{4,6}, and only capture ICMP message.

dbeec9bda6 selftests: fix too long argument
[ Upstream commit c363eb48ad ]

With some shells, the command construed for install of bpf selftests becomes
too large due to long list of files:

make[1]: execvp: /bin/sh: Argument list too long
make[1]: *** [../lib.mk:73: install] Error 127

Currently, each of the file lists is replicated three times in the command:
in the shell 'if' condition, in the 'echo' and in the 'rsync'. Reduce that
by one instance by using make conditionals and separate the echo and rsync
into two shell commands. (One would be inclined to just remove the '@' at
the beginning of the rsync command and let 'make' echo it by itself;
unfortunately, it appears that the '@' in the front of mkdir silences output
also for the following commands.)

Also, separate handling of each of the lists to its own shell command.

The semantics of the makefile is unchanged before and after the patch. The
ability of individual test directories to override INSTALL_RULE is retained.

d847804f8f perf ui gtk: Add missing zalloc object
commit 604e2139a1 upstream.

When we moved zalloc.o to the library we missed gtk library which needs
it compiled in, otherwise the missing __zfree symbol will cause the
library to fail to load.

Adding the zalloc object to the gtk library build.

20e559d8f7 selftests: Install settings files to fix TIMEOUT failures
commit b9167c8078 upstream.

Commit 852c8cbf34 ("selftests/kselftest/runner.sh: Add 45 second
timeout per test") added a 45 second timeout for tests, and also added
a way for tests to customise the timeout via a settings file.

For example the ftrace tests take multiple minutes to run, so they
were given longer in commit b43e78f65b ("tracing/selftests: Turn off
timeout setting").

This works when the tests are run from the source tree. However if the
tests are installed with "make -C tools/testing/selftests install",
the settings files are not copied into the install directory. When the
tests are then run from the install directory the longer timeouts are
not applied and the tests timeout incorrectly.

So add the settings files to TEST_FILES of the appropriate Makefiles
to cause the settings files to be installed using the existing install
logic.

5b3beff4e8 ipv6: Fix route replacement with dev-only route
[ Upstream commit e404b8c7cf ]

After commit 2759647247 ("ipv6: fix ECMP route replacement") it is no
longer possible to replace an ECMP-able route by a non ECMP-able route.
For example,
	ip route add 2001:db8::1/128 via fe80::1 dev dummy0
	ip route replace 2001:db8::1/128 dev dummy0
does not work as expected.

Tweak the replacement logic so that point 3 in the log of the above commit
becomes:
3. If the new route is not ECMP-able, and no matching non-ECMP-able route
exists, replace matching ECMP-able route (if any) or add the new route.

We can now summarize the entire replace semantics to:
When doing a replace, prefer replacing a matching route of the same
"ECMP-able-ness" as the replace argument. If there is no such candidate,
fallback to the first route found.

fb81480206 bpf: Selftests build error in sockmap_basic.c
commit f2e97dc126 upstream.

Fix following build error. We could push a tcp.h header into one of the
include paths, but I think its easy enough to simply pull in the three
defines we need here. If we end up using more of tcp.h at some point
we can pull it in later.

/home/john/git/bpf/tools/testing/selftests/bpf/prog_tests/sockmap_basic.c: In function ‘connected_socket_v4’:
/home/john/git/bpf/tools/testing/selftests/bpf/prog_tests/sockmap_basic.c:20:11: error: ‘TCP_REPAIR_ON’ undeclared (first use in this function)
  repair = TCP_REPAIR_ON;
           ^
/home/john/git/bpf/tools/testing/selftests/bpf/prog_tests/sockmap_basic.c:20:11: note: each undeclared identifier is reported only once for each function it appears in
/home/john/git/bpf/tools/testing/selftests/bpf/prog_tests/sockmap_basic.c:29:11: error: ‘TCP_REPAIR_OFF_NO_WP’ undeclared (first use in this function)
  repair = TCP_REPAIR_OFF_NO_WP;

Then with fix,

$ ./test_progs -n 44
#44/1 sockmap create_update_free:OK
#44/2 sockhash create_update_free:OK
#44 sockmap_basic:OK

16ec28640d selftests/eeh: Bump EEH wait time to 60s
[ Upstream commit 414f50434a ]

Some newer cards supported by aacraid can take up to 40s to recover
after an EEH event. This causes spurious failures in the basic EEH
self-test since the current maximim timeout is only 30s.

Fix the immediate issue by bumping the timeout to a default of 60s,
and allow the wait time to be specified via an environmental variable
(EEH_MAX_WAIT).

b911c5e868 selftests: bpf: Reset global state between reuseport test runs
[ Upstream commit 51bad0f056 ]

Currently, there is a lot of false positives if a single reuseport test
fails. This is because expected_results and the result map are not cleared.

Zero both after individual test runs, which fixes the mentioned false
positives.

838bddc295 x86/decoder: Add TEST opcode to Group3-2
[ Upstream commit 8b7e20a7ba ]

Add TEST opcode to Group3-2 reg=001b as same as Group3-1 does.

Commit

  12a78d43de ("x86/decoder: Add new TEST instruction pattern")

added a TEST opcode assignment to f6 XX/001/XXX (Group 3-1), but did
not add f7 XX/001/XXX (Group 3-2).

Actually, this TEST opcode variant (ModRM.reg /1) is not described in
the Intel SDM Vol2 but in AMD64 Architecture Programmer's Manual Vol.3,
Appendix A.2 Table A-6. ModRM.reg Extensions for the Primary Opcode Map.

Without this fix, Randy found a warning by insn_decoder_test related

e44b48f5bb tools lib api fs: Fix gcc9 stringop-truncation compilation error

GCC9 introduced string hardening mechanisms, which exhibits the error
during fs api compilation:

error: '__builtin_strncpy' specified bound 4096 equals destination size
[-Werror=stringop-truncation]

This comes when the length of copy passed to strncpy is is equal to
destination size, which could potentially lead to buffer overflow.

There is a need to mitigate this potential issue by limiting the size of
destination by 1 and explicitly terminate the destination with NULL.

cf03458ab2 selftests/net: make so_txtime more robust to timer variance
[ Upstream commit ea6a547669 ]

The SO_TXTIME test depends on accurate timers. In some virtualized
environments the test has been reported to be flaky. This is easily
reproduced by disabling kvm acceleration in Qemu.

Allow greater variance in a run and retry to further reduce flakiness.

Observed errors are one of two kinds: either the packet arrives too
early or late at recv(), or it was dropped in the qdisc itself and the
recv() call times out.

In the latter case, the qdisc queues a notification to the error
queue of the send socket. Also explicitly report this cause.

b752d473b1 selftests: settings: tests can be in subsubdirs
[ Upstream commit ac87813d43 ]

Commit 852c8cbf34 ("selftests/kselftest/runner.sh: Add 45 second
timeout per test") adds support for a new per-test-directory "settings"
file. But this only works for tests not in a sub-subdirectories, e.g.

 - tools/testing/selftests/rtc (rtc) is OK,
 - tools/testing/selftests/net/mptcp (net/mptcp) is not.

We have to increase the timeout for net/mptcp tests which are not
upstreamed yet but this fix is valid for other tests if they need to add
a "settings" file, see the full list with:

  tools/testing/selftests/*/*/**/Makefile

Note that this patch changes the text header message printed at the end
of the execution but this text is modified only for the tests that are
in sub-subdirectories, e.g.

  ok 1 selftests: net/mptcp: mptcp_connect.sh

Before we had:

  ok 1 selftests: mptcp: mptcp_connect.sh

But showing the full target name is probably better, just in case a
subsubdir has the same name as another one in another subdirectory.

56953ccd7f kselftest: Minimise dependency of get_size on C library interfaces
[ Upstream commit 6b64a650f0 ]

It was observed[1] on arm64 that __builtin_strlen led to an infinite
loop in the get_size selftest.  This is because __builtin_strlen (and
other builtins) may sometimes result in a call to the C library
function.  The C library implementation of strlen uses an IFUNC
resolver to load the most efficient strlen implementation for the
underlying machine and hence has a PLT indirection even for static
binaries.  Because this binary avoids the C library startup routines,
the PLT initialization never happens and hence the program gets stuck
in an infinite loop.

On x86_64 the __builtin_strlen just happens to expand inline and avoid
the call but that is not always guaranteed.

Further, while testing on x86_64 (Fedora 31), it was observed that the
test also failed with a segfault inside write() because the generated
code for the write function in glibc seems to access TLS before the
syscall (probably due to the cancellation point check) and fails
because TLS is not initialised.

To mitigate these problems, this patch reduces the interface with the
C library to just the syscall function.  The syscall function still
sets errno on failure, which is undesirable but for now it only
affects cases where syscalls fail.

7bee7eabf0 perf stat: Don't report a null stalled cycles per insn metric
commit 80cc7bb6c1 upstream.

For data collected on machines with front end stalled cycles supported,
such as found on modern AMD CPU families, commit 146540fb54 ("perf
stat: Always separate stalled cycles per insn") introduces a new line in
CSV output with a leading comma that upsets some automated scripts.
Scripts have to use "-e ex_ret_instr" to work around this issue, after
upgrading to a version of perf with that commit.

We could add "if (have_frontend_stalled && !config->csv_sep)" to the not
(total && avg) else clause, to emphasize that CSV users are usually
scripts, and are written to do only what is needed, i.e., they wouldn't
typically invoke "perf stat" without specifying an explicit event list.

But - let alone CSV output - why should users now tolerate a constant
0-reporting extra line in regular terminal output?:

BEFORE:

$ sudo perf stat --all-cpus -einstructions,cycles -- sleep 1

 Performance counter stats for 'system wide':

       181,110,981      instructions              #    0.58  insn per cycle
                                                  #    0.00  stalled cycles per insn
       309,876,469      cycles

       1.002202582 seconds time elapsed

The user would not like to see the now permanent:

  "0.00  stalled cycles per insn"

line fixture, as it gives no useful information.

So this patch removes the printing of the zeroed stalled cycles line
altogether, almost reverting the very original commit fb4605ba47
("perf stat: Check for frontend stalled for metrics"), which seems like
it was written to normalize --metric-only column output of common Intel
machines at the time: modern Intel machines have ceased to support the
genericised frontend stalled metrics AFAICT.

AFTER:

$ sudo perf stat --all-cpus -einstructions,cycles -- sleep 1

 Performance counter stats for 'system wide':

       244,071,432      instructions              #    0.69  insn per cycle
       355,353,490      cycles

       1.001862516 seconds time elapsed

Output behaviour when stalled cycles is indeed measured is not affected
(BEFORE == AFTER):

$ sudo perf stat --all-cpus -einstructions,cycles,stalled-cycles-frontend -- sleep 1

 Performance counter stats for 'system wide':

       247,227,799      instructions              #    0.63  insn per cycle
                                                  #    0.26  stalled cycles per insn
       394,745,636      cycles
        63,194,485      stalled-cycles-frontend   #   16.01% frontend cycles idle

cb675fde4c selftests/bpf: Test freeing sockmap/sockhash with a socket in it
commit 5d3919a953 upstream.

Commit 7e81a35302 ("bpf: Sockmap, ensure sock lock held during tear
down") introduced sleeping issues inside RCU critical sections and while
holding a spinlock on sockmap/sockhash tear-down. There has to be at least
one socket in the map for the problem to surface.

This adds a test that triggers the warnings for broken locking rules. Not a
fix per se, but rather tooling to verify the accompanying fixes. Run on a
VM with 1 vCPU to reproduce the warnings.

1dfc34bd00 bpftool: Don't crash on missing xlated program instructions
commit d95f1e8b46 upstream.

Turns out the xlated program instructions can also be missing if
kptr_restrict sysctl is set. This means that the previous fix to check the
jited_prog_insns pointer was insufficient; add another check of the
xlated_prog_insns pointer as well.

Fixes: 5b79bcdf03 ("bpftool: Don't crash on missing jited insns or ksyms")
Fixes: cae73f2339 ("bpftool: use bpf_program__get_prog_info_linear() in prog.c:do_dump()")

726599c637 tools/kvm_stat: Fix kvm_exit filter name
commit 5fcf3a55a6 upstream.

The filter name is fixed to "exit_reason" for some kvm_exit events, no
matter what architect we have. Actually, the filter name ("exit_reason")
is only applicable to x86, meaning it's broken on other architects
including aarch64.

This fixes the issue by providing various kvm_exit filter names, depending
on architect we're on. Afterwards, the variable filter name is picked and
applied through ioctl(fd, SET_FILTER).

1f5f3f65f9 selftests: bpf: Ignore FIN packets for reuseport tests
commit 8bec4f665e upstream.

The reuseport tests currently suffer from a race condition: FIN
packets count towards DROP_ERR_SKB_DATA, since they don't contain
a valid struct cmd. Tests will spuriously fail depending on whether
check_results is called before or after the FIN is processed.

Exit the BPF program early if FIN is set.

commit f1c3656c6d upstream.

The same with commit 4e59afbbed ("selftests/bpf: skip nmi test when perf
hw events are disabled"), it would make more sense to skip the
test_stacktrace_build_id_nmi test if the setup (e.g. virtual machines) has

commit 7145fcfffe upstream.

when the following command is done on a fresh clone of the kernel tree,

 [root@f31 tc-testing]# ./tdc.py -c bpf

test cases that need to build the eBPF sample program fail systematically,
because 'buildebpfPlugin' is unable to install the kernel headers (i.e, the
'khdr' target fails). Pass the correct environment to 'make', in place of
ENVIR, to allow running these tests.

4eed5d3bb1 cpupower: Revert library ABI changes from commit ae2917093f
commit 41ddb7e1f7 upstream.

Commit ae2917093f ("tools/power/cpupower: Display boost frequency
separately") modified the library function:

struct cpufreq_available_frequencies
*cpufreq_get_available_frequencies(unsigned int cpu)

to
struct cpufreq_frequencies
*cpufreq_get_frequencies(const char *type, unsigned int cpu)

This patch recovers the old API and implements the new functionality
in a newly introduce method:
struct cpufreq_boost_frequencies
*cpufreq_get_available_frequencies(unsigned int cpu)

This one should get merged into stable kernels back to 5.0 when
the above had been introduced.

47dbff7950 objtool: Silence build output
commit 6ec14aa7a5 upstream.

The sync-check.sh script prints out the path due to a "cd -" at the end
of the script, even on silent builds. This isn't even needed, since the
script is executed in our build instead of sourced (so it won't change
the working directory of the surrounding build anyway).

Just remove the cd to make the build silent.

20e1bbe5cf perf report: Fix no libunwind compiled warning break s390 issue
[ Upstream commit c3314a74f8 ]

Commit 800d3f5616 ("perf report: Add warning when libunwind not
compiled in") breaks the s390 platform. S390 uses libdw-dwarf-unwind for
call chain unwinding and had no support for libunwind.

So the warning "Please install libunwind development packages during the
perf build." caused the confusion even if the call-graph is displayed
correctly.

This patch adds checking for HAVE_DWARF_SUPPORT, which is set when
libdw-dwarf-unwind is compiled in.

e77625d1f8 tools lib: Fix builds when glibc contains strlcpy()
commit 6c4798d3f0 upstream.

Disable a couple of compilation warnings (which are treated as errors)
on strlcpy() definition and declaration, allowing users to compile perf
and kernel (objtool) when:

1. glibc have strlcpy() (such as in ALT Linux since 2004) objtool and
   perf build fails with this (in gcc):

  In file included from exec-cmd.c:3:
  tools/include/linux/string.h:20:15: error: redundant redeclaration of ‘strlcpy’ [-Werror=redundant-decls]
     20 | extern size_t strlcpy(char *dest, const char *src, size_t size);

2. clang ignores `-Wredundant-decls', but produces another warning when
   building perf:

    CC       util/string.o
  ../lib/string.c:99:8: error: attribute declaration must precede definition [-Werror,-Wignored-attributes]
  size_t __weak strlcpy(char *dest, const char *src, size_t size)
  ../../tools/include/linux/compiler.h:66:34: note: expanded from macro '__weak'
  # define __weak                 __attribute__((weak))
  /usr/include/bits/string_fortified.h:151:8: note: previous definition is here
  __NTH (strlcpy (char *__restrict __dest, const char *__restrict __src,

Committer notes:

The

 #pragma GCC diagnostic

directive was introduced in gcc 4.6, so check for that as well.

e9fac00465 perf c2c: Fix return type for histogram sorting comparision functions
commit c1c8013ec3 upstream.

Commit 722ddfde36 ("perf tools: Fix time sorting") changed - correctly
so - hist_entry__sort to return int64. Unfortunately several of the
builtin-c2c.c comparison routines only happened to work due the cast
caused by the wrong return type.

This causes meaningless ordering of both the cacheline list, and the
cacheline details page. E.g a simple:

  perf c2c record -a sleep 3
  perf c2c report

will result in cacheline table like
  =================================================

i.e. with the list not being ordered by Total Hitm.
