pull-request: bpf-next 2023-11-30
We've added 30 non-merge commits during the last 7 day(s) which contain
a total of 58 files changed, 1598 insertions(+), 154 deletions(-).
The main changes are:
1) Add initial TX metadata implementation for AF_XDP with support in mlx5
and stmmac drivers. Two types of offloads are supported right now, that
is, TX timestamp and TX checksum offload, from Stanislav Fomichev with
stmmac implementation from Song Yoong Siang.
2) Change BPF verifier logic to validate global subprograms lazily instead
of unconditionally before the main program, so they can be guarded using
BPF CO-RE techniques, from Andrii Nakryiko.
3) Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter, from Jiri Olsa.
4) Use pkg-config in BPF selftests to determine ld flags which is
in particular needed for linking statically, from Akihiko Odaki.
5) Fix a few BPF selftest failures to adapt to the upcoming LLVM18,
from Yonghong Song.

To avoid duplicated code in different MPTCP selftests, we can add
and use helpers defined in mptcp_lib.sh.
wait_local_port_listen() helper is defined in diag.sh, mptcp_connect.sh,
mptcp_join.sh and simult_flows.sh, export it into mptcp_lib.sh and
rename it with mptcp_lib_ prefix. Use this new helper in all these
scripts.
Note: We only have IPv4 connections in this helper, not looking at IPv6
(tcp6) but that's OK because we only have IPv4 connections here in diag.sh.

When we get a packet on port 9091, we swap src/dst and send it out.
At this point we also request the timestamp and checksum offloads.
Checksum offload is verified by looking at the tcpdump on the other side.
The tool prints pseudo-header csum and the final one it expects.
The final checksum actually matches the incoming packets checksum
because we only flip the src/dst and don't change the payload.
Some other related changes:
- switched to zerocopy mode by default; new flag can be used to force
old behavior
- request fixed tx_metadata_len headroom
- some other small fixes (umem size, fill idx+i, etc)

Cleanup net namespaces and other resources if we get a SIGINT (Ctrl-C).
As user visible resources are allocated on a per test basis, it's only
required to catch this condition when (possibly) running tests.
So far calling post_suite is enough to free up anything that might
linger.

Same init_rng() in both tests. The function reads /dev/urandom to
initialize srand(). In case of failure, it falls back onto the
entropy in the uninitialized variable. Not sure if this is on purpose.
But failure reading urandom should be rare, so just fail hard. While
at it, convert to getrandom(). Which man 4 random suggests is simpler
and more robust.

Further analysis shows llvm upstream patch [1] is responsible for the above
failures. For example, for function bpf_fentry_test7() in net/bpf/test_run.c,
without [1], the asm code is:
0000000000000400 <bpf_fentry_test7>:
400: f3 0f 1e fa endbr64
404: e8 00 00 00 00 callq 0x409 <bpf_fentry_test7+0x9>
409: 48 89 f8 movq %rdi, %rax
40c: c3 retq
40d: 0f 1f 00 nopl (%rax)
... and with [1], the asm code is:
0000000000005d20 <bpf_fentry_test7.specialized.1>:
5d20: e8 00 00 00 00 callq 0x5d25 <bpf_fentry_test7.specialized.1+0x5>
5d25: c3 retq
... and <bpf_fentry_test7.specialized.1> is called instead of <bpf_fentry_test7>
and this caused test failures for #13/#77 etc. except #356.
For test case #356/17, with [1] (progs/test_global_func17.c)), the main prog
looks like:
0000000000000000 <global_func17>:
0: b4 00 00 00 2a 00 00 00 w0 = 0x2a
1: 95 00 00 00 00 00 00 00 exit
... which passed verification while the test itself expects a verification
failure.
Let us add 'barrier_var' style asm code in both places to prevent function
specialization which caused selftests failure.

Add a few test that validate BPF verifier's lazy approach to validating
global subprogs.
We check that global subprogs that are called transitively through
another global subprog is validated.
We also check that invalid global subprog is not validated, if it's not
called from the main program.
And we also check that main program is always validated first, before
any of the subprogs.

Slightly change BPF verifier logic around eagerness and order of global
subprog validation. Instead of going over every global subprog eagerly
and validating it before main (entry) BPF program is verified, turn it
around. Validate main program first, mark subprogs that were called from
main program for later verification, but otherwise assume it is valid.
Afterwards, go over marked global subprogs and validate those,
potentially marking some more global functions as being called. Continue
this process until all (transitively) callable global subprogs are
validated. It's a BFS traversal at its heart and will always converge.
This is an important change because it allows to feature-gate some
subprograms that might not be verifiable on some older kernel, depending
on supported set of features.
E.g., at some point, global functions were allowed to accept a pointer
to memory, which size is identified by user-provided type.
Unfortunately, older kernels don't support this feature. With BPF CO-RE
approach, the natural way would be to still compile BPF object file once
and guard calls to this global subprog with some CO-RE check or using
.rodata variables. That's what people do to guard usage of new helpers
or kfuncs, and any other new BPF-side feature that might be missing on
old kernels.
That's currently impossible to do with global subprogs, unfortunately,
because they are eagerly and unconditionally validated. This patch set
aims to change this, so that in the future when global funcs gain new
features, those can be guarded using BPF CO-RE techniques in the same
fashion as any other new kernel feature.
Two selftests had to be adjusted in sync with these changes.
test_global_func12 relied on eager global subprog validation failing
before main program failure is detected (unknown return value). Fix by
making sure that main program is always valid.
verifier_subprog_precision's parent_stack_slot_precise subtest relied on
verifier checkpointing heuristic to do a checkpoint at instruction #5,
but that's no longer true because we don't have enough jumps validated
before reaching insn #5 due to global subprogs being validated later.
Other than that, no changes, as one would expect.

Tune message length calculation to make this test work on machines
where 'getpagesize()' returns >32KB. Now maximum message length is not
hardcoded (on machines above it was smaller than 'getpagesize()' return
value, thus we get negative value and test fails), but calculated at
runtime and always bigger than 'getpagesize()' result. Reproduced on
aarch64 with 64KB page size.
