Hi there,
As part of our ongoing research effort to understand the discrepancies
among Linux, macOS (FreeBSD), and Windows. We discover a violation of
the way Linux hanldes incoming TCP packet, specifically ACK number
validation.
According to RFC 793, "If the ACK is a duplicate (SEG.ACK < SND.UNA

Hi
Today I made some real life traffic tests with kernel 4.15.0-rc9
but when traffic reach 50Gbit/s and about 6Mpps cpou load rises fast
from 48% to 100% for all cpu cores.
Here is some graph that presenting how cpu load rises when there was
more pps.

Actually, I can trigger this really easily, even with an rsync from one
disk to another. Though that also smells a little like networking in
the traces. Maybe netdev has ideas.

This implements ndo_poll_controller callback which is necessary to

Hello,
I'm using this to enable netconsole on a consumer device built around the
Marvell Berlin BG2CD SoC.

syzbot reported a lockdep splat in gen_new_estimator() /
est_fetch_counters() when attempting to lock est->stats_lock.
Since est_fetch_counters() is called from BH context from timer
interrupt, we need to block BH as well when calling it from process
context.

While playing with using libbpf for the Suricata project, we had
issues LLVM >= 4.0.1 generating ELF files that could not be loaded
with libbpf (tools/lib/bpf/).
During the troubleshooting phase, I wrote a test program and improved
the debugging output in libbpf. I turned this into a selftests

If clang >= 4.0.1 is missing the option '-target bpf', it will cause
llc/llvm to create two ELF sections for "Exception Frames", with
section names '.eh_frame' and '.rel.eh_frame'.
The BPF ELF loader library libbpf fails when loading files with these
sections. The other in-kernel BPF ELF loader i
I recently fixed up a lot of commits that forgot to keep the tooling
headers in sync. And then I forgot to do the same thing in commit
cb5f7334d479 ("bpf: add comments to BPF ld/ldx sizes"). Let correct
that before people notice ;-).
Lawrence did partly fix/sync this for bpf.h in commit d6d4f60c3

While debugging a bpf ELF loading issue, I needed to correlate the
ELF section number with the failed relocation section reference.
Thus, add section numbers/index to the pr_debug.
In debug mode, also print section that were skipped. This helped
me identify that a section (.eh_frame) was skipped,

Non-JSON tc qdisc output used to print the "requeues" statistic
twice. Commit 4fcec7f3665b ("tc: jsonify stats2") tried to preserve
this behaviour for both standard output and JSON, but used the wrong
statistic (q.qlen). Also duplicating keys in JSON is not allowed,
so the second occurrence shoul
