These errors might be because of linux/mount.h is not included. This patch resolves that issue.

This is what I've been using to see whether the spec makes sense.
A small subset of getters (mostly the unprivileged ones) is implemented.
Some setters (channels) also work.
Setters for messages with bitmasks are not implemented.
Initially I was trying to make this tool look 1:1 like real ethtool,
but eventually gave up :-)

currently, users can skip individual test cases by means of writing
"skip": "yes"
in the scenario file. Extend this functionality, introducing 'dependsOn':
it's optional property like "skip", but the value contains a command (for
example, a probe on iproute2 to check if it supports a specific feature).
If such property is present, tdc executes that command and skips the test
when the return value is non-zero.

This selftest was introduced recently in the commit cited below. It misses
several check_err() invocations to actually verify that the previous
command succeeded. When these are added, the first one fails, because
besides the addresses added by hand, there can be a link-local address
added by the kernel. Adjust the check to expect at least three addresses
instead of exactly three, and add the missing check_err's.
Furthermore, the explanatory comments assume that the address with no
protocol is $addr2, when in fact it is $addr3. Update the comments.

The second argument of the bpf_kptr_xchg() helper function is
ARG_PTR_TO_BTF_ID_OR_NULL. A recent patch fixed a bug whereby the
verifier would fail with an internal error message if a program invoked
the helper with a PTR_TO_BTF_ID | PTR_MAYBE_NULL register. This testcase
adds some testcases to ensure that it fails gracefully moving forward.
Before the fix, these testcases would have failed an error resembling
the following:

This adds test which checks case when data of newly received skbuff is
appended to the last skbuff in the socket's queue. It looks like simple
test with 'send()' and 'recv()', but internally it triggers logic which
appends one received skbuff to another. Test checks that this feature
works correctly.
This test is actual only for virtio transport.

SEC("freplace") (i.e., BPF_PROG_TYPE_EXT) programs are not loadable as
is through veristat, as kernel expects actual program's FD during
BPF_PROG_LOAD time, which veristat has no way of knowing.
Unfortunately, freplace programs are a pretty important class of
programs, especially when dealing with XDP chaining solutions, which
rely on EXT programs.
So let's do our best and teach veristat to try to guess the original
program type, based on program's context argument type. And if guessing
process succeeds, we manually override freplace/EXT with guessed program
type using bpf_program__set_type() setter to increase chances of proper
BPF verification.
We rely on BTF and maintain a simple lookup table. This process is
obviously not 100% bulletproof, as valid program might not use context
and thus wouldn't have to specify correct type. Also, __sk_buff is very
ambiguous and is the context type across many different program types.
We pick BPF_PROG_TYPE_CGROUP_SKB for now, which seems to work fine in
practice so far. Similarly, some program types require specifying attach
type, and so we pick one out of possible few variants.
Best effort at its best. But this makes veristat even more widely
applicable.

If user explicitly overrides programs's type with
bpf_program__set_type() API call, we need to disassociate whatever
SEC_DEF handler libbpf determined initially based on program's SEC()
definition, as it's not goind to be valid anymore and could lead to
crashes and/or confusing failures.
Also, fix up bpf_prog_test_load() helper in selftests/bpf, which is
force-setting program type (even if that's completely unnecessary; this
is quite a legacy piece of code), and thus should expect auto-attach to
not work, yet one of the tests explicitly relies on auto-attach for
testing.
Instead, force-set program type only if it differs from the desired one.

Make the broadcast cutoff configurable through netlink. Note
that macvlan is weird because there is no central device for
us to configure (the lowerdev could be anything). So all the
options are duplicated over what could be thousands of child
devices.
IFLA_MACVLAN_BC_QUEUE_LEN took the approach of taking the maximum
of all child device settings. This is unnecessary as we could
simply store the option in the port device and take the last
child device that gets updated as the value to use.

Double-free error in bpf_linker__free() was reported by James Hilliard.
The error is caused by miss-use of realloc() in extend_sec().
The error occurs when two files with empty sections of the same name
are linked:
- when first file is processed:
- extend_sec() calls realloc(dst->raw_data, dst_align_sz)
with dst->raw_data == NULL and dst_align_sz == 0;
- dst->raw_data is set to a special pointer to a memory block of
size zero;
- when second file is processed:
- extend_sec() calls realloc(dst->raw_data, dst_align_sz)
with dst->raw_data == <special pointer> and dst_align_sz == 0;
- realloc() "frees" dst->raw_data special pointer and returns NULL;
- extend_sec() exits with -ENOMEM, and the old dst->raw_data value
is preserved (it is now invalid);
- eventually, bpf_linker__free() attempts to free dst->raw_data again.
This patch fixes the bug by avoiding -ENOMEM exit for dst_align_sz == 0.
The fix was suggested by Andrii Nakryiko <andrii.nakryiko@gmail.com>.

coming from an enum of type "flags". We also allow flipping an

the 'enum-as-flags' property of an attribute.

This patch adds a task storage benchmark to the existing
local-storage-create benchmark.
For task storage,
./bench --storage-type task --batch-size 32:
bpf_ma: Summary: creates 30.456 ± 0.507k/s ( 30.456k/prod), 6.08 kmallocs/create
no bpf_ma: Summary: creates 31.962 ± 0.486k/s ( 31.962k/prod), 6.13 kmallocs/create
./bench --storage-type task --batch-size 64:
bpf_ma: Summary: creates 30.197 ± 1.476k/s ( 30.197k/prod), 6.08 kmallocs/create
no bpf_ma: Summary: creates 31.103 ± 0.297k/s ( 31.103k/prod), 6.13 kmallocs/create
