Instead of parsing text-based /proc/<pid>/maps file, try to use
PROCMAP_QUERY ioctl() to simplify and speed up data fetching.
This logic is used to do uprobe file offset calculation, so any bugs in
this logic would manifest as failing uprobe BPF selftests.
This also serves as a simple demonstration of one of the intended uses.

Depending on kernel parameters, x86 jit generates either retq or jump
to rethunk for 'exit' instruction. The difference could be seen when
kernel is booted with and without mitigations=off parameter.

At the moment, when test_loader.c:get_current_arch() can't determine
the arch, it returns 0. The arch check in run_subtest() looks as
follows:
if ((get_current_arch() & spec->arch_mask) == 0) {
test__skip();
return;
}
Which means that all test_loader based tests would be skipped if arch
could not be determined. get_current_arch() recognizes x86_64, arm64
and riscv64. Which means that CI skips test_loader tests for s390.
Fix this by making sure that get_current_arch() always returns
non-zero value. In combination with default spec->arch_mask == -1 this
should cover all possibilities.

Currently a number of SVE/SME related tests have almost identical
functions to enumerate all supported vector lengths. However over time
the copy&pasted code has diverged, allowing some bugs to creep in:
- fake_sigreturn_sme_change_vl reports a failure, not a SKIP if only
one vector length is supported (but the SVE version is fine)
- fake_sigreturn_sme_change_vl tries to set the SVE vector length, not
the SME one (but the other SME tests are fine)
- za_no_regs keeps iterating forever if only one vector length is
supported (but za_regs is correct)
Since those bugs seem to be mostly copy&paste ones, let's consolidate
the enumeration loop into one shared function, and just call that from
each test. That should fix the above bugs, and prevent similar issues
from happening again.

A few tests check if nettest exists in the $PATH before adding
$PWD to $PATH and re-checking. They don't discard stderr on
the first check (and nettest is built as part of selftests,
so it's pretty normal for it to not be available in system $PATH).
This leads to output noise:
which: no nettest in (/home/virtme/tools/fs/bin:/home/virtme/tools/fs/sbin:/home/virtme/tools/fs/usr/bin:/home/virtme/tools/fs/usr/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin)
Add a common helper for the check which does silence stderr.
There is another small functional change hiding here, because pmtu.sh
and fib_rule_tests.sh used to return from the test case rather than
completely exit. Building nettest is not hard, there should be no need
to maintain the ability to selectively skip cases in its absence.

At some point there'd been a dumb braino during the dup_fd()
calling conventions change; caught by smatch and immediately fixed.
The trouble is, there had been no test coverage for the dup_fd() failure
handling - neither in kselftests nor in LTP. Fortunately, it can be
triggered on stock kernel - ENOMEM would require fault injection, but
EMFILE can be had with sysctl alone (fs.nr_open).

Both __xlated and __jited work with disassembly.
It is logical to have both work in a similar manner.
This commit updates __xlated macro handling in test_loader.c by making
it expect matches on sequential lines, same way as __jited operates.
For example:
__xlated("1: *(u64 *)(r10 -16) = r1") ;; matched on line N
__xlated("3: r0 = &(void __percpu *)(r0)") ;; matched on line N+1
Also:
__xlated("1: *(u64 *)(r10 -16) = r1") ;; matched on line N
__xlated("...") ;; not matched
__xlated("3: r0 = &(void __percpu *)(r0)") ;; mantched on any
;; line >= N

__jited(" nopl (%rax,%rax)")
__jited(" xorq %rax, %rax")
...
__naked void some_test(void)

}
Allow regular expressions in patterns, same way as in __msg.
By default assume that each __jited pattern has to be matched on the
next consecutive line of the disassembly, e.g.:
__jited(" endbr64") # matched on line N
__jited(" nopl (%rax,%rax)") # matched on line N+1
If match occurs on a wrong line an error is reported.
To override this behaviour use __jited("..."), e.g.:
__jited(" endbr64") # matched on line N
__jited("...") # not matched
__jited(" nopl (%rax,%rax)") # matched on any line >= N

This commit adds a utility function to get disassembled text for jited
representation of a BPF program designated by file descriptor.
Function prototype looks as follows:
int get_jited_program_text(int fd, char *text, size_t text_sz)
Where 'fd' is a file descriptor for the program, 'text' and 'text_sz'
refer to a destination buffer for disassembled text.
Output format looks as follows:
18: 77 06 ja L0
1a: 50 pushq %rax
1b: 48 89 e0 movq %rsp, %rax
1e: eb 01 jmp L1
20: 50 L0: pushq %rax
21: 50 L1: pushq %rax
^ ^^^^^^^^ ^ ^^^^^^^^^^^^^^^^^^
| binary insn | textual insn
| representation | representation

The code and makefile changes are inspired by jit_disasm.c from bpftool.
Use llvm libraries to disassemble BPF program instead of libbfd to avoid
issues with disassembly output stability pointed out in [1].
Selftests makefile uses Makefile.feature to detect if LLVM libraries
are available. If that is not the case selftests build proceeds but
the function returns -EOPNOTSUPP at runtime.

Upcoming changes require a notation to specify regular expression
matches for regular verifier log messages, disassembly of BPF
instructions, disassembly of jited instructions.
Neither basic nor extended POSIX regular expressions w/o additional
escaping are good for this role because of wide use of special
characters in disassembly, for example:
movq -0x10(%rbp), %rax ;; () are special characters
cmpq $0x21, %rax ;; $ is a special character
*(u64 *)(r10 -16) = r1 ;; * and () are special characters
This commit borrows syntax from LLVM's FileCheck utility.
It replaces __regex macro with ability to embed regular expressions
in __msg patters using "{{" "}}" pairs for escaping.
Syntax for __msg patterns:
pattern := (<verbatim text> | regex)*
regex := "{{" <posix extended regular expression> "}}"
For example, pattern "foo{{[0-9]+}}" matches strings like
"foo0", "foo007", etc.

__msg, __regex and __xlated tags are based on
__attribute__((btf_decl_tag("..."))) annotations.
Clang de-duplicates such annotations, e.g. the following
two sequences of tags are identical in final BTF:
/* seq A */ /* seq B */
__tag("foo") __tag("foo")
__tag("bar") __tag("bar")
__tag("foo")
Fix this by adding a unique suffix for each tag using __COUNTER__
pre-processor macro. E.g. here is a new definition for __msg:
#define __msg(msg) \
__attribute__((btf_decl_tag("comment:test_expect_msg=" XSTR(__COUNTER__) "=" msg)))
Using this definition the "seq A" from example above is translated to
BTF as follows:
[..] DECL_TAG 'comment:test_expect_msg=0=foo' type_id=X component_idx=-1
[..] DECL_TAG 'comment:test_expect_msg=1=bar' type_id=X component_idx=-1
[..] DECL_TAG 'comment:test_expect_msg=2=foo' type_id=X component_idx=-1
Surprisingly, this bug affects a single existing test:
verifier_spill_fill/old_stack_misc_vs_cur_ctx_ptr,
where sequence of identical messages was expected in the log.

Suppose log="foo bar buz" and msg->substr="bar".
In such case current match processing logic would update 'log' as
follows: log += strlen(msg->substr); -> log += 3 -> log=" bar".
However, the intent behind the 'log' update is to make it point after
the successful match, e.g. to make log=" buz" in the example above.

Looking at timestamped output of netdev CI reveals that
most of the time in forwarding tests for custom route
hashing is spent on a single case, namely the test which
uses ping (mausezahn does not support flow labels).
On a non-debug kernel we spend 714 of 730 total test
runtime (97%) on this test case. While having flow label
support in a traffic gen tool / mausezahn would be best,
we can significantly speed up the loop by putting ip vrf exec
outside of the iteration.
In a test of 1000 pings using a normal loop takes 50 seconds
to finish. While using:
ip vrf exec $vrf sh -c "$loop-body"
takes 12 seconds (1/4 of the time).
Some of the slowness is likely due to our inefficient virtualization
setup, but even on my laptop running "ip link help" 16k times takes
25-30 seconds, so I think it's worth optimizing even for fastest
setups.

Existing LSMs have centered around the concept of access to a resource
