0b62157672 ANDROID: Incremental fs: Build merkle tree when enabling verity
For incfs files that were created without a merkle tree, enabling verity
requires building a merkle tree first. Although this is the same logic
as verity performs, it is not that easy to reconcile the two given that
incfs has the merkle tree potentially when verity is not enabled.

Add FS_IOC_ENABLE_VERITY ioctl

When called, calculate measurement, validate signature against fsverity,

This does not (yet) preserve the verity status once the inode is

2b02985bf8 objtool: Fix seg fault with Clang non-section symbols
commit 44f6a7c075 upstream.

The Clang assembler likes to strip section symbols, which means objtool
can't reference some text code by its section.  This confuses objtool
greatly, causing it to seg fault.

The fix is similar to what was done before, for ORC reloc generation:

  e81e072443 ("objtool: Support Clang non-section symbols in ORC generation")

Factor out that code into a common helper and use it for static call
reloc generation as well.

7d8cffdedc FROMGIT: kasan: prefix global functions with kasan_
Patch series "kasan: HW_TAGS tests support and fixes", v4.

This patchset adds support for running KASAN-KUnit tests with the
hardware tag-based mode and also contains a few fixes.

This patch (of 15):

There's a number of internal KASAN functions that are used across multiple
source code files and therefore aren't marked as static inline.  To avoid
littering the kernel function names list with generic function names,
prefix all such KASAN functions with kasan_.

As a part of this change:

- Rename internal (un)poison_range() to kasan_(un)poison() (no _range)
  to avoid name collision with a public kasan_unpoison_range().

- Rename check_memory_region() to kasan_check_range(), as it's a more
  fitting name.

9c8bb3eac0 objtool: Don't fail the kernel build on fatal errors
[ Upstream commit 655cf86548 ]

This is basically a revert of commit 644592d328 ("objtool: Fail the
kernel build on fatal errors").

That change turned out to be more trouble than it's worth.  Failing the
build is an extreme measure which sometimes gets too much attention and
blocks CI build testing.

These fatal-type warnings aren't yet as rare as we'd hope, due to the
ever-increasing matrix of supported toolchains/plugins and their
fast-changing nature as of late.

Also, there are more people (and bots) looking for objtool warnings than
ever before, so even non-fatal warnings aren't likely to be ignored for
long.

89ca15b71b selftests/powerpc: Only test lwm/stmw on big endian
[ Upstream commit dd3a44c06f ]

Newer binutils (>= 2.36) refuse to assemble lmw/stmw when building in
little endian mode. That breaks compilation of our alignment handler
test:

  /tmp/cco4l14N.s: Assembler messages:
  /tmp/cco4l14N.s:1440: Error: `lmw' invalid when little-endian
  /tmp/cco4l14N.s:1814: Error: `stmw' invalid when little-endian
  make[2]: *** [../../lib.mk:139: /output/kselftest/powerpc/alignment/alignment_handler] Error 1

These tests do pass on little endian machines, as the kernel will
still emulate those instructions even when running little
endian (which is arguably a kernel bug).

But we don't really need to test that case, so ifdef those
instructions out to get the alignment test building again.

9d6dbf4e37 objtool: Don't add empty symbols to the rbtree
[ Upstream commit a2e38dffcd ]

Building with the Clang assembler shows the following warning:

  arch/x86/kernel/ftrace_64.o: warning: objtool: missing symbol for insn at offset 0x16

The Clang assembler strips section symbols.  That ends up giving
objtool's find_func_containing() much more test coverage than normal.
Turns out, find_func_containing() doesn't work so well for overlapping
symbols:

     2: 000000000000000e     0 NOTYPE  LOCAL  DEFAULT    2 fgraph_trace
     3: 000000000000000f     0 NOTYPE  LOCAL  DEFAULT    2 trace
     4: 0000000000000000   165 FUNC    GLOBAL DEFAULT    2 __fentry__
     5: 000000000000000e     0 NOTYPE  GLOBAL DEFAULT    2 ftrace_stub

The zero-length NOTYPE symbols are inside __fentry__(), confusing the
rbtree search for any __fentry__() offset coming after a NOTYPE.

Try to avoid this problem by not adding zero-length symbols to the
rbtree.  They're rare and aren't needed in the rbtree anyway.

One caveat, this actually might not end up being the right fix.
Non-empty overlapping symbols, if they exist, could have the same
problem.  But that would need bigger changes, let's see if we can get
away with the easy fix for now.

4d06445ad7 tools/power/x86/intel-speed-select: Set higher of cpuinfo_max_freq or base_frequency
[ Upstream commit bbaa2e95e2 ]

In some case when BIOS disabled turbo, cpufreq cpuinfo_max_freq can be
lower than base_frequency at higher config level. So, in that case set
scaling_min_freq to base_frequency.

f667433cb3 tools/power/x86/intel-speed-select: Set scaling_max_freq to base_frequency
[ Upstream commit f981dc171c ]

When BIOS disables turbo, The scaling_max_freq in cpufreq sysfs will be
limited to config level 0 base frequency. But when user selects a higher
config levels, this will result in higher base frequency. But since
scaling_max_freq is still old base frequency, the performance will still
be limited. So when the turbo is disabled and cpufreq base_frequency is
higher than scaling_max_freq, update the scaling_max_freq to the
base_frequency.

6daa52884c xfrm: Fix wraparound in xfrm_policy_addr_delta()
[ Upstream commit da64ae2d35 ]

Use three-way comparison for address components to avoid integer
wraparound in the result of xfrm_policy_addr_delta(). This ensures
that the search trees are built and traversed correctly.

Treat IPv4 and IPv6 similarly by returning 0 when prefixlen == 0.
Prefix /0 has only one equivalence class.

8ea899803b selftests: xfrm: fix test return value override issue in xfrm_policy.sh
[ Upstream commit f6e9ceb7a7 ]

When running this xfrm_policy.sh test script, even with some cases
marked as FAIL, the overall test result will still be PASS:

$ sudo ./xfrm_policy.sh
PASS: policy before exception matches
FAIL: expected ping to .254 to fail (exceptions)
PASS: direct policy matches (exceptions)
PASS: policy matches (exceptions)
FAIL: expected ping to .254 to fail (exceptions and block policies)
PASS: direct policy matches (exceptions and block policies)
PASS: policy matches (exceptions and block policies)
FAIL: expected ping to .254 to fail (exceptions and block policies after hresh changes)

PASS: policy matches (exceptions and block policies after hthresh change in ns3)
FAIL: expected ping to .254 to fail (exceptions and block policies after htresh change to normal)
PASS: direct policy matches (exceptions and block policies after htresh change to normal)
PASS: policy matches (exceptions and block policies after htresh change to normal)
PASS: policies with repeated htresh change
$ echo $?
0

This is because the $lret in check_xfrm() is not a local variable.
Therefore when a test failed in check_exceptions(), the non-zero $lret
will later get reset to 0 when the next test calls check_xfrm().

With this fix, the final return value will be 1. Make it easier for
testers to spot this failure.

c6fd968f58 objtool: Don't fail on missing symbol table
commit 1d489151e9 upstream.

Thanks to a recent binutils change which doesn't generate unused
symbols, it's now possible for thunk_64.o be completely empty without
CONFIG_PREEMPTION: no text, no data, no symbols.

We could edit the Makefile to only build that file when
CONFIG_PREEMPTION is enabled, but that will likely create confusion
if/when the thunks end up getting used by some other code again.

Just ignore it and move on.

cc4e8ab452 UPSTREAM: KVM: arm64: selftests: Filter out DEMUX registers
DEMUX register presence depends on the host's hardware (the
CLIDR_EL1 register to be precise). This means there's no set
of them that we can bless and that it's possible to encounter
new ones when running on different hardware (which would
generate "Consider adding them ..." messages, but we'll never
want to add them.)

Remove the ones we have in the blessed list and filter them
out of the new list, but also provide a new command line switch
to list them if one so desires.

7e2bf98d53 selftests/powerpc: Fix exit status of pkey tests
commit 92a5e1fdb2 upstream.

Since main() does not return a value explicitly, the
return values from FAIL_IF() conditions are ignored
and the tests can still pass irrespective of failures.
This makes sure that we always explicitly return the
correct test exit status.

3b56eecdc7 perf evlist: Fix id index for heterogeneous systems
[ Upstream commit fc705fecf3 ]

perf_evlist__set_sid_idx() updates perf_sample_id with the evlist map
index, CPU number and TID. It is passed indexes to the evsel's cpu and
thread maps, but references the evlist's maps instead. That results in
using incorrect CPU numbers on heterogeneous systems. Fix it by using
evsel maps.

The id index (PERF_RECORD_ID_INDEX) is used by AUX area tracing when in
sampling mode. Having an incorrect CPU number causes the trace data to
be attributed to the wrong CPU, and can result in decoder errors because
the trace data is then associated with the wrong process.

Committer notes:

Keep the class prefix convention in the function name, switching from
perf_evlist__set_sid_idx() to perf_evsel__set_sid_idx().

1200a5bc68 bpf: Fix selftest compilation on clang 11
commit fb3558127c upstream.

Before this patch, profiler.inc.h wouldn't compile with clang-11 (before
the __builtin_preserve_enum_value LLVM builtin was introduced in
https://reviews.llvm.org/D83242).

Another test that uses this builtin (test_core_enumval) is conditionally
skipped if the compiler is too old. In that spirit, this patch inhibits
part of populate_cgroup_info(), which needs this CO-RE builtin. The
selftests build again on clang-11.

The affected test (the profiler test) doesn't pass on clang-11 because
it's missing https://reviews.llvm.org/D85570, but at least the test suite
as a whole compiles. The test's expected failure is already called out in
the README.

43fe730804 UPSTREAM: kselftest/arm64: check GCR_EL1 after context switch
[ Upstream commit 29f0808816 ]

This test is specific to MTE and verifies that the GCR_EL1 register is
context switched correctly.

It spawns 1024 processes and each process spawns 5 threads.  Each thread
writes a random setting of GCR_EL1 through the prctl() system call and
reads it back verifying that it is the same.  If the values are not the
same it reports a failure.

Note: The test has been extended to verify that even SYNC and ASYNC mode
setting is preserved correctly over context switching.

26865769ed selftests: netfilter: Pass family parameter "-f" to conntrack tool
commit fab336b424 upstream.

Fix nft_conntrack_helper.sh false fail report:

1) Conntrack tool need "-f ipv6" parameter to show out ipv6 traffic items.

2) Sleep 1 second after background nc send packet, to make sure check
is after this statement executed.

False report:
FAIL: ns1-lkjUemYw did not show attached helper ip set via ruleset
PASS: ns1-lkjUemYw connection on port 2121 has ftp helper attached
...

After fix:
PASS: ns1-2hUniwU2 connection on port 2121 has ftp helper attached
PASS: ns2-2hUniwU2 connection on port 2121 has ftp helper attached

09b3e0bc8e perf intel-pt: Fix 'CPU too large' error
commit 5501e9229a upstream.

In some cases, the number of cpus (nr_cpus_online) is confused with the
maximum cpu number (nr_cpus_avail), which results in the error in the
example below:

Example on system with 8 cpus:

 Before:
   # echo 0 > /sys/devices/system/cpu/cpu2/online
   # ./perf record --kcore -e intel_pt// taskset --cpu-list 7 uname
   Linux
   [ perf record: Woken up 1 times to write data ]
   [ perf record: Captured and wrote 0.147 MB perf.data ]
   # ./perf script --itrace=e
   Requested CPU 7 too large. Consider raising MAX_NR_CPUS
   0x25908 [0x8]: failed to process type: 68 [Invalid argument]

 After:
   # ./perf script --itrace=e
   #

Fixes: 8c7274691f ("perf machine: Replace MAX_NR_CPUS with perf_env::nr_cpus_online")

[ Upstream commit 3503ee6c0b ]

The udpgro.sh will always return 0 (unless the bpf selftest was not
build first) even if there are some failed sub test-cases.

Therefore the kselftest framework will report this case is OK.

Check and return the exit status of each test to make it easier to
spot real failures.

commit 4a443a5177 upstream.

To pick the changes from:

  3ceb6543e9 ("fscrypt: remove kernel-internal constants from UAPI header")

That don't result in any changes in tooling, just addressing this perf
build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/fscrypt.h' differs from latest version at 'include/uapi/linux/fscrypt.h'

commit a5c9ca76a1 upstream.

For IPv6 traffic, mausezahn needs to be invoked with '-6'. Otherwise an
error is returned:

 # ip netns exec me mausezahn veth1 -B 2001:db8:101::2 -A 2001:db8:91::1 -c 0 -t tcp "dp=1-1023, flags=syn"
 Failed to set source IPv4 address. Please check if source is set to a valid IPv4 address.

31a3520409 bpftool: Fix compilation failure for net.o with older glibc
commit 6f02b540d7 upstream.

For older glibc ~2.17, #include'ing both linux/if.h and net/if.h
fails due to complaints about redefinition of interface flags:

  CC       net.o
In file included from net.c:13:0:
/usr/include/linux/if.h:71:2: error: redeclaration of enumerator ‘IFF_UP’
  IFF_UP    = 1<<0,  /* sysfs */
  ^
/usr/include/net/if.h:44:5: note: previous definition of ‘IFF_UP’ was here
     IFF_UP = 0x1,  /* Interface is up.  */

The issue was fixed in kernel headers in [1], but since compilation
of net.c picks up system headers the problem can recur.

Dropping #include <linux/if.h> resolves the issue and it is
not needed for compilation anyhow.

4abc2dbd88 selftests/bpf: Clarify build error if no vmlinux
commit 1a3449c194 upstream.

If Makefile cannot find any of the vmlinux's in its VMLINUX_BTF_PATHS list,
it tries to run btftool incorrectly, with VMLINUX_BTF unset:

    bpftool btf dump file $(VMLINUX_BTF) format c

Such that the keyword 'format' is misinterpreted as the path to vmlinux.
The resulting build error message is fairly cryptic:

      GEN      vmlinux.h
    Error: failed to load BTF from format: No such file or directory

This patch makes the failure reason clearer by yielding this instead:

    Makefile:...: *** Cannot find a vmlinux for VMLINUX_BTF at any of
    "{paths}".  Stop.

541c22aad3 tools: selftests: add test for changing routes with PTMU exceptions
[ Upstream commit 5316a7c013 ]

Adds new 2 new tests to the PTMU script: pmtu_ipv4/6_route_change.

These tests explicitly test for a recently discovered problem in the
IPv6 routing framework where PMTU exceptions were not properly released
when replacing a route via "ip route change ...".

After creating PMTU exceptions, the route from the device A to R1 will be
replaced with a new route, then device A will be deleted. If the PMTU
exceptions were properly cleaned up by the kernel, this device deletion
will succeed. Otherwise, the unregistration of the device will stall, and
messages such as the following will be logged in dmesg:

unregister_netdevice: waiting for veth_A-R1 to become free. Usage count = 4
