Subject: [PATCH v4 bpf-next 0/9] bpf: Misc improvements
Date: Tue, 9 Feb 2021 19:36:25 -0800 [thread overview]
Message-ID: <20210210033634.62081-1-alexei.starovoitov@gmail.com> (raw)
From: Alexei Starovoitov <ast@kernel.org>
v4:
- split migrate_disable into separate patch
v3:
- address review comments
- improve recursion selftest
Several bpf improvements:
- optimize prog stats
- compute stats for sleepable progs
- prevent recursion fentry/fexit and sleepable progs
- allow map-in-map and per-cpu maps in sleepable progs
Alexei Starovoitov (9):
bpf: Optimize program stats
bpf: Run sleepable programs with migration disabled
bpf: Compute program stats for sleepable programs
bpf: Add per-program recursion prevention mechanism
selftest/bpf: Add a recursion test
bpf: Count the number of times recursion was prevented
selftests/bpf: Improve recursion selftest
bpf: Allows per-cpu maps and map-in-map in sleepable programs
selftests/bpf: Add a test for map-in-map and per-cpu maps in sleepable
progs
