strncat()'s third argument is how many bytes will be added *in addition* to
already existing bytes in destination. Plus extra zero byte will be added
after that. So existing use in test_sockmap has many opportunities to overflow
the string and cause memory corruptions. And in this case, GCC complains for
a good reason.

ways for selftests/bpf to test various kernel module-related functionality:
raw tracepoint, fentry/fexit/fmod_ret, etc. This module will be auto-loaded by

losetup on busybox does not output the name of loop device on using
-f with --show. It also doesn't support -j to find the loop devices
for a given backing file. losetup is updated to use "-a" which is
available on busybox.
blkid does not support options (-s and -o) to only display the uuid, so
parse the output instead.
Not all environments have mkfs.ext4, the test requires a loop device
with a backing image file which could formatted with any filesystem.
Update to using mkfs.ext2 which is available on busybox.

Splice (copy_file_range) doesn't work on all filesystems. I'm running
test kernels on top of my read-only disk image and it uses plan9 under the
hood. This prevents test_local_storage from successfully passing.
There is really no technical reason to use splice, so lets do
old-school read/write to copy file; this should work in all

Flavored variants of test_progs (e.g. test_progs-no_alu32) change their
working directory to the corresponding subdirectory (e.g. no_alu32).
Since the setup script required by test_ima (ima_setup.sh) is not
mentioned in the dependencies, it does not get copied to these
subdirectories and causes flavored variants of test_ima to fail.
Adding the script to TRUNNER_EXTRA_FILES ensures that the file is also
copied to the subdirectories for the flavored variants of test_progs.

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.

The test does the following:
- Mounts a loopback filesystem and appends the IMA policy to measure
executions only on this file-system. Restricting the IMA policy to
a particular filesystem prevents a system-wide IMA policy change.
- Executes an executable copied to this loopback filesystem.
- Calls the bpf_ima_inode_hash in the bprm_committed_creds hook and
checks if the call succeeded and checks if a hash was calculated.
The test shells out to the added ima_setup.sh script as the setup is
better handled in a shell script and is more complicated to do in the
test program or even shelling out individual commands from C.
The list of required configs (i.e. IMA, SECURITYFS,
IMA_{WRITE,READ}_POLICY) for running this test are also updated.
