Subject: [PATCH bpf-next v10 0/2] bpf: Allow bpf_skb_event_output for more prog types
Date: Tue, 23 Jul 2019 17:07:23 -0700	[thread overview]
Message-ID: <20190724000725.15634-1-allanzhang@google.com> (raw)

Software event output is only enabled by a few prog types right now (TC,
LWT out, XDP, sockops). Many other skb based prog types need
bpf_skb_event_output to produce software event.

More prog types are enabled to access bpf_skb_event_output in this

v10 changes:
Resubmit (v9 is submitted when bpf branch is closed).

v9 changes:
add "Acked-by" field.

v8 changes:
No actual change, just cc to netdev@vger.kernel.org and
v7 patches are acked by Song Liu.

v7 changes:
Reformat from hints by scripts/checkpatch.pl, including Song's comment
on signed-off-by name to captical case in cover letter.
3 of hints are ignored:
1. new file mode.
2. SPDX-License-Identifier for event_output.c since all files under
   this dir have no such line.
3. "Macros ... enclosed in parentheses" for macro in event_output.c
   due to code's nature.

Change patch 02 subject "bpf:..." to "selftests/bpf:..."

Fix Signed-off-by, fix fixup map creation.

v5 changes:
Fix typos, reformat comments in event_output.c, move revision history to
cover letter.

v4 changes:
Reformating log message.

v3 changes:
