dfa210cf9f tools/accounting/getdelays.c: fix netlink attribute length 
commit 4054ab64e2 upstream.

A recent change to the netlink code: 6e237d099f ("netlink: Relax attr
validation for fixed length types") logs a warning when programs send
messages with invalid attributes (e.g., wrong length for a u32).  Yafang
reported this error message for tools/accounting/getdelays.c.

send_cmd() is wrongly adding 1 to the attribute length.  As noted in
include/uapi/linux/netlink.h nla_len should be NLA_HDRLEN + payload
length, so drop the +1.

Fixes: 9e06d3f9f6 ("per task delay accounting taskstats interface: documentation fix")

[ Upstream commit 1f81c5efc0 ]

Some Chromebook BIOS' do not export an ACPI LPIT, which is how
Linux finds the residency counter for CPU and SYSTEM low power states,
that is exports in /sys/devices/system/cpu/cpuidle/*residency_us

When these sysfs attributes are missing, check the debugfs attrubte
from the pmc_core driver, which accesses the same counter value.

a1081413e8 perf map: Fix off by one in strncpy() size argument 
commit db2c549407 upstream.

This patch fixes an off-by-one error in strncpy size argument in
tools/perf/util/map.c. The issue is that in:

        strncmp(filename, "/system/lib/", 11)

the passed string literal: "/system/lib/" has 12 bytes (without the NULL
byte) and the passed size argument is 11. As a result, the logic won't
match the ending "/" byte and will pass filepaths that are stored in
other directories e.g. "/system/libmalicious/bin" or just
"/system/libmalicious".

This functionality seems to be present only on Android. I assume the
/system/ directory is only writable by the root user, so I don't think
this bug has much (or any) security impact.

Fixes: eca8183699 ("perf tools: Add automatic remapping of Android libraries")

683cf66377 tools: Let O= makes handle a relative path with -C option 
commit be40920fbf upstream.

When I tried to compile tools/perf from the top directory with the -C
option, the O= option didn't work correctly if I passed a relative path:

  $ make O=BUILD -C tools/perf/
  make: Entering directory '/home/mhiramat/ksrc/linux/tools/perf'
    BUILD:   Doing 'make -j8' parallel build
  ../scripts/Makefile.include:4: *** O=/home/mhiramat/ksrc/linux/tools/perf/BUILD does not exist.  Stop.
  make: *** [Makefile:70: all] Error 2
  make: Leaving directory '/home/mhiramat/ksrc/linux/tools/perf'

The O= directory existence check failed because the check script ran in
the build target directory instead of the directory where I ran the make
command.

To fix that, once change directory to $(PWD) and check O= directory,
since the PWD is set to where the make command runs.

a2d866c50a perf probe: Do not depend on dwfl_module_addrsym() 
commit 1efde27542 upstream.

Do not depend on dwfl_module_addrsym() because it can fail on user-space
shared libraries.

Actually, same bug was fixed by commit 664fee3dc3 ("perf probe: Do not
use dwfl_module_addrsym if dwarf_diename finds symbol name"), but commit
07d3698578 ("perf probe: Fix wrong address verification) reverted to
get actual symbol address from symtab.

This fixes it again by getting symbol address from DIE, and only if the
DIE has only address range, it uses dwfl_module_addrsym().

5f2b792d31 perf probe: Fix to delete multiple probe event 
commit 6b8d68f1ce upstream.

When we put an event with multiple probes, perf-probe fails to delete
with filters. This comes from a failure to list up the event name
because of overwrapping its name.

To fix this issue, skip to list up the event which has same name.

Without this patch:

  # perf probe -l \*
    probe_perf:map__map_ip (on perf_sample__fprintf_brstackoff:21@
    probe_perf:map__map_ip (on perf_sample__fprintf_brstackoff:25@

  # perf probe -d \*
  "*" does not hit any event.
    Error: Failed to delete events. Reason: No such file or directory (Code: -2)

With it:

  # perf probe -d \*
  Removed event: probe_perf:map__map_ip

[ Upstream commit 2de7fb60a4 ]

Building cpupower with -fno-common in CFLAGS results in errors due to
multiple definitions of the 'cpu_count' and 'start_time' variables.

./utils/idle_monitor/snb_idle.o:./utils/idle_monitor/cpupower-monitor.h:28:
multiple definition of `cpu_count';
./utils/idle_monitor/nhm_idle.o:./utils/idle_monitor/cpupower-monitor.h:28:

The -fno-common option will be enabled by default in GCC 10.

c35aa36fec selftests/rseq: Fix out-of-tree compilation 
[ Upstream commit ef89d05451 ]

Currently if you build with O=... the rseq tests don't build:

  $ make O=$PWD/output -C tools/testing/selftests/ TARGETS=rseq
  make: Entering directory '/linux/tools/testing/selftests'
  ...
  make[1]: Entering directory '/linux/tools/testing/selftests/rseq'
  gcc -O2 -Wall -g -I./ -I../../../../usr/include/ -L./ -Wl,-rpath=./  -shared -fPIC rseq.c -lpthread -o /linux/output/rseq/librseq.so
  gcc -O2 -Wall -g -I./ -I../../../../usr/include/ -L./ -Wl,-rpath=./  basic_test.c -lpthread -lrseq -o /linux/output/rseq/basic_test
  /usr/bin/ld: cannot find -lrseq
  collect2: error: ld returned 1 exit status

This is because the library search path points to the source
directory, not the output.

We can fix it by changing the library search path to $(OUTPUT).

c61868ef27 perf bench futex-wake: Restore thread count default to online CPU count 
commit f649bd9dd5 upstream.

Since commit 3b2323c2c1 ("perf bench futex: Use cpumaps") the default
number of threads the benchmark uses got changed from number of online
CPUs to zero:

  $ perf bench futex wake
  # Running 'futex/wake' benchmark:
  Run summary [PID 15930]: blocking on 0 threads (at [private] futex 0x558b8ee4bfac), waking up 1 at a time.
  [Run 1]: Wokeup 0 of 0 threads in 0.0000 ms
  [...]
  [Run 10]: Wokeup 0 of 0 threads in 0.0000 ms
  Wokeup 0 of 0 threads in 0.0004 ms (+-40.82%)

Restore the old behavior by grabbing the number of online CPUs via
cpu->nr:

  $ perf bench futex wake
  # Running 'futex/wake' benchmark:
  Run summary [PID 18356]: blocking on 8 threads (at [private] futex 0xb3e62c), waking up 1 at a time.
  [Run 1]: Wokeup 8 of 8 threads in 0.0260 ms
  [...]
  [Run 10]: Wokeup 8 of 8 threads in 0.0270 ms
  Wokeup 8 of 8 threads in 0.0419 ms (+-24.35%)

3625e9dfd8 ktest: Add timeout for ssh sync testing 
commit 4d00fc477a upstream.

Before rebooting the box, a "ssh sync" is called to the test machine to see
if it is alive or not. But if the test machine is in a partial state, that
ssh may never actually finish, and the ktest test hangs.

Add a 10 second timeout to the sync test, which will fail after 10 seconds
and then cause the test to reboot the test machine.

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.

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.

d15530fc92 perf intel-bts: Fix endless record after being terminated 
commit 783fed2f35 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 intel_bts event is disabled, we don't enable it again here.

0f121ace25 selftests: forwarding: vxlan_bridge_1d: use more proper tos value 
[ Upstream commit 9b64208f74 ]

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.

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

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.

it compiled in, otherwise the missing __zfree symbol will cause the
library to fail to load.

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
to this issue as below.

e44b48f5bb tools lib api fs: Fix gcc9 stringop-truncation compilation error 
[ Upstream commit 6794200fa3 ]

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.
