prog_tests/verifier.c would be used as a host for verifier/*.c tests
migrated to use inline assembly and run from test_progs.
The run_test_aux() function mimics the test_verifier behavior

Extends test_loader.c:test_loader__run_subtests() by allowing to
execute BPF_PROG_TEST_RUN bpf command for selected programs.
This is similar to functionality provided by test_verifier.
Adds the following new attributes controlling test_loader behavior:
__retval(...)
__retval_unpriv(...)
* If any of these attributes is present, the annotated program would
be executed using libbpf's bpf_prog_test_run_opts() function.
* If __retval is present, the test run would be done for program
loaded in privileged mode.
* If __retval_unpriv is present, the test run would be done for
program loaded in unprivileged mode.
* To mimic test_verifier behavior, the actual run is initiated in
privileged mode.
* The value returned by a test run is compared against retval
parameter.
The retval attribute takes one of the following parameters:
- a decimal number
- a hexadecimal number (must start from '0x')
- any of a three special literals (provided for compatibility with
test_verifier):
- INT_MIN
- POINTER_VALUE
- TEST_DATA_LEN
An example of the attribute usage:
SEC("socket")
__description("return 42")
__success __success_unpriv __retval(42)
__naked void the_42_test(void)
{
asm volatile (" \
r0 = 42; \
exit; \
" ::: __clobber_all);
}

Extends test_loader.c:test_loader__run_subtests() by allowing to
execute tests in unprivileged mode, similar to test_verifier.c.
Adds the following new attributes controlling test_loader behavior:
__msg_unpriv
__success_unpriv
__failure_unpriv
* If any of these attributes is present the test would be loaded in
unprivileged mode.
* If only "privileged" attributes are present the test would be loaded
only in privileged mode.
* If both "privileged" and "unprivileged" attributes are present the
test would be loaded in both modes.
* If test has to be executed in both modes, __msg(text) is specified
and __msg_unpriv is not specified the behavior is the same as if
__msg_unpriv(text) is specified.
* For test filtering purposes the name of the program loaded in
unprivileged mode is derived from the usual program name by adding
`@unpriv' suffix.
Also adds attribute '__description'. This attribute specifies text to
be used instead of a program name for display and filtering purposes.

KF_RELEASE kfuncs are not currently treated as having KF_TRUSTED_ARGS,
even though they have a superset of the requirements of KF_TRUSTED_ARGS.
Like KF_TRUSTED_ARGS, KF_RELEASE kfuncs require a 0-offset argument, and
don't allow NULL-able arguments. Unlike KF_TRUSTED_ARGS which require
_either_ an argument with ref_obj_id > 0, _or_ (ref->type &
BPF_REG_TRUSTED_MODIFIERS) (and no unsafe modifiers allowed), KF_RELEASE
only allows for ref_obj_id > 0. Because KF_RELEASE today doesn't
automatically imply KF_TRUSTED_ARGS, some of these requirements are
enforced in different ways that can make the behavior of the verifier
feel unpredictable. For example, a KF_RELEASE kfunc with a NULL-able
argument will currently fail in the verifier with a message like, "arg#0
is ptr_or_null_ expected ptr_ or socket" rather than "Possibly NULL
pointer passed to trusted arg0". Our intention is the same, but the
semantics are different due to implemenetation details that kfunc authors
and BPF program writers should not need to care about.
Let's make the behavior of the verifier more consistent and intuitive by
having KF_RELEASE kfuncs imply the presence of KF_TRUSTED_ARGS. Our
eventual goal is to have all kfuncs assume KF_TRUSTED_ARGS by default
anyways, so this takes us a step in that direction.
Note that it does not make sense to assume KF_TRUSTED_ARGS for all
KF_ACQUIRE kfuncs. KF_ACQUIRE kfuncs can have looser semantics than
KF_RELEASE, with e.g. KF_RCU | KF_RET_NULL. We may want to have
KF_ACQUIRE imply KF_TRUSTED_ARGS _unless_ KF_RCU is specified, but that
can be left to another patch set, and there are no such subtleties to
address for KF_RELEASE.

It is a good practice to state explicitly which are the required Python
packages needed in a particular project to run it. The most commonly
used way is to store them in the `requirements.txt` file*.
*URL: https://pip.pypa.io/en/stable/reference/requirements-file-format/
Currently user needs to figure out himself that Python needs `PyYAML`
and `jsonschema` (and theirs requirements) packages to use the tool.
Add the `requirements.txt` for user convenience.
How to use it:
1) (optional) Create and activate empty virtual environment:
python3.X -m venv venv3X
source ./venv3X/bin/activate
2) Install all the required packages:
pip install -r requirements.txt
or
python -m pip install -r requirements.txt
3) Run the script!
The `requirements.txt` file was tested for:
* Python 3.6
* Python 3.8
* Python 3.10

Exception: Unknown type at dpll pin-state 1 u8
I'm not that familiar with ynl code, but from a quick peek, I suspect
that couple other types are missing for both encoding and decoding.
Ignoring those here as I'm scratching my local itch only.
Fix the issue by adding u8 attr packing.

pull-request: bpf 2023-03-23
We've added 8 non-merge commits during the last 13 day(s) which contain
a total of 21 files changed, 238 insertions(+), 161 deletions(-).
The main changes are:
1) Fix verification issues in some BPF programs due to their stack usage
patterns, from Eduard Zingerman.
2) Fix to add missing overflow checks in xdp_umem_reg and return an error
in such case, from Kal Conley.
3) Fix and undo poisoning of strlcpy in libbpf given it broke builds for
libcs which provided the former like uClibc-ng, from Jesus Sanchez-Palencia.
4) Fix insufficient bpf_jit_limit default to avoid users running into hard
to debug seccomp BPF errors, from Daniel Borkmann.
5) Fix driver return code when they don't support a bpf_xdp_metadata kfunc
to make it unambiguous from other errors, from Jesper Dangaard Brouer.
6) Two BPF selftest fixes to address compilation errors from recent changes
in kernel structures, from Alexei Starovoitov.

Extract the list of all tests into a variable, ALL_TESTS. Then assume the
environment variable TESTS holds the list of tests to actually run, falling
back to ALL_TESTS if TESTS is empty. This is the same interface that
forwarding selftests use to make the set of tests to run configurable.
In addition to this, allow setting the value explicitly through a command
line option "-t" along the lines of what fib_nexthops.sh does.

Create a pair of sockets that utilize the congestion control algorithm
under a particular name. Then switch up this congestion control
algorithm to another implementation and check whether newly created
connections using the same cc name now run the new implementation.
Also, try to update a link with a struct_ops that is without
BPF_F_LINK or with a wrong or different name. These cases should fail
due to the violation of assumptions. To update a bpf_link of a
struct_ops, it must be replaced with another struct_ops that is
identical in type and name and has the BPF_F_LINK flag.
The other test case is to create links from the same struct_ops more
than once. It makes sure a struct_ops can be used repeatly.
