[ Upstream commit 732fa32330667a80ce4985ca81b6e9d6b2ad2072 ]
The test_xdp_redirect.sh script uses a bash feature, '&>'. On systems,
e.g. Debian, where '/bin/sh' is dash, this will not work as
expected. Use bash in the shebang to get the expected behavior.
Further, using 'set -e' means that the error of a command cannot be
captured without the command being executed with '&&' or '||'. Let us
restructure the ping-commands, and use them as an if-expression, so
that we can capture the return value.
v4: Added missing Fixes:, and removed local variables. (Andrii)
v3: Reintroduced /bin/bash, and kept 'set -e'. (Andrii)
v2: Kept /bin/sh and removed bashisms. (Randy)

[ Upstream commit dd3a44c06f7b4f14e90065bf05d62c255b20005f ]
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.

[ Upstream commit da64ae2d35d3673233f0403b035d4c6acbf71965 ]
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.

[ Upstream commit f6e9ceb7a7fc321a31a9dde93a99b7b4b016a3b3 ]
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: direct policy matches (exceptions and block policies after hresh changes)

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.

commit 92a5e1fdb286851d5bd0eb966b8d075be27cf5ee 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

commit fb3558127cb62ba2dea9e3d0efa1bb1d7e5eee2a 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.

commit 1a3449c19407a28f7019a887cdf0d6ba2444751a 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.

[ Upstream commit 5316a7c0130acf09bfc8bb0092407006010fcccc ]
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

If the size of the error log is too big to send via email, and the sending
fails, it wont email any result. This can be confusing for the user who is
waiting for an email on the completion of the tests.
If it fails to send email, then try again without the log file stating that
it failed to send an email. Obviously this will not be of use if the sending
of email failed for some other reasons, but it will at least give the user
some information when it fails for the most common reason.

The test program udpgso_bench_rx always invokes the poll()
syscall with a timeout of 10ms. If a larger timeout is specified
via the command line, udpgso_bench_rx is supposed to do multiple
poll() calls till the timeout is expired or an event is received.
Currently the poll() loop errors out after the first invocation with
no events, and may causes self-tests failure alike:
failed
GRO with custom segment size ./udpgso_bench_rx: poll: 0x0 expected 0x1
This change addresses the issue allowing the poll() loop to consume
all the configured timeout.

The test fails because of a recent fix to the verifier, even though this
program is valid. In details what happens is:
7: (61) r1 = *(u32 *)(r0 +0)
Load a 32-bit value, with signed bounds [S32_MIN, S32_MAX]. The bounds
of the 64-bit value are [0, U32_MAX]...
8: (65) if r1 s> 0xffffffff goto pc+1
... therefore this is always true (the operand is sign-extended).
10: (b4) w2 = 11
11: (6d) if r2 s> r1 goto pc+1
When true, the 64-bit bounds become [0, 10]. The 32-bit bounds are still
[S32_MIN, 10].
13: (64) w1 <<= 2
Because this is a 32-bit operation, the verifier propagates the new
32-bit bounds to the 64-bit ones, and the knowledge gained from insn 11
is lost.
14: (0f) r0 += r1
15: (7a) *(u64 *)(r0 +0) = 4
Then the verifier considers r0 unbounded here, rejecting the test. To
make the test work, change insn 8 to check the sign of the 32-bit value.

After a 32-bit load followed by a branch, the verifier would reduce the
maximum bound of the register to 0x7fffffff, allowing a user to bypass
bound checks. Ensure such a program is rejected.
In the second test, the 64-bit compare should not sufficient to
determine whether the signed 32-bit lower bound is 0, so the verifier
should reject the second branch.

A few of the tests in test_offload.py expects to see a certain number of
maps created, and checks this by counting the number of maps returned by
bpftool. There is already a filter that will remove any maps already there
at the beginning of the test, but bpftool now creates a map for the PID
iterator rodata on each invocation, which makes the map count wrong. Fix
this by also filtering the pid_iter.rodata map by name when counting.

When setting the ethtool feature flag fails (as expected for the test), the
kernel now tracks that the feature was requested to be 'off' and refuses to
subsequently disable it again. So reset it back to 'on' so a subsequent
disable (that's not supposed to fail) can succeed.

Commit 7f0a838254bd ("bpf, xdp: Maintain info on attached XDP BPF programs

returned when attaching of XDP programs failed. This broke test_offload.py,
so let's fix the test to reflect this.

Since commit 6f8a57ccf851 ("bpf: Make verifier log more relevant by
default"), the verifier discards log messages for successfully-verified
programs. This broke test_offload.py which is looking for a verification
message from the driver callback. Change test_offload.py to use the toggle
in netdevsim to make the verification fail before looking for the
verification message.

The error handling in hugetlb_allocate_area() was incorrect for the
hugetlb_shared test case.
Previously the behavior was:
- mmap a hugetlb area
- If this fails, set the pointer to NULL, and carry on
- mmap an alias of the same hugetlb fd
- If this fails, munmap the original area
If the original mmap failed, it's likely the second one did too. If
both failed, we'd blindly try to munmap a NULL pointer, causing a
SIGSEGV. Instead, "goto fail" so we return before trying to mmap the
alias.
This issue can be hit "in real life" by forgetting to set
/proc/sys/vm/nr_hugepages (leaving it at 0), and then trying to run the
hugetlb_shared test.
Another small improvement is, when the original mmap fails, don't just
print "it failed": perror(), so we can see *why*. :)

VRF table, the NS for the source link-local address of the originator
might be sent to the wrong interface.
This patch ensures that packets with link-local addr source is doing a
lookup with the orig_iif when the destination addr indicates that it
is strict.

The current memory region move test correctly handles the situation that
the second (realigning) memslot move operation would temporarily trigger
MMIO until it completes, however it does not handle the case in which the
first (misaligning) move operation does this, too.
This results in false test assertions in case it does so.
Fix this by handling temporary MMIO from the first memslot move operation
in the test guest code, too.

This issue was first noticed when I was testing different kernels on
Oracle Linux 8 which as Fedora 30+ adopts BLS as default. Even though a
kernel entry was added successfully and the index of that kernel entry was
retrieved correctly, ktest still wouldn't reboot the system into
user-specified kernel.
The bug was spotted in subroutine reboot_to where the if-statement never
checks for REBOOT_TYPE "grub2bls", therefore the desired entry will not be
set for the next boot.
Add a check for "grub2bls" so that $grub_reboot $grub_number can
be run before a reboot if REBOOT_TYPE is "grub2bls" then we can boot to
the correct kernel.
