We are no longer using Travis. As such, we should move away from a lot of CI functionality located in a folder called travis-ci/. This change renames the travis-ci/ directory to the more generic ci/. To preserve backwards compatibility until all "consumers" have transitioned, we add a symbolic link called travis-ci back. It will be removed in the near term future.

Subject: [PATCH bpf-next] selftests/bpf: Fix OOB write in test_verifier
|
|
Date: Tue, 14 Dec 2021 07:18:00 +0530 [thread overview]
|
|
Message-ID: <20211214014800.78762-1-memxor@gmail.com> (raw)
|
|
|
|
The commit referenced below added fixup_map_timer support (to create a
|
|
BPF map containing timers), but failed to increase the size of the
|
|
map_fds array, leading to out of bounds write. Fix this by changing
|
|
MAX_NR_MAPS to 22.
|
|
|
|
Fixes: e60e6962c503 ("selftests/bpf: Add tests for restricted helpers")
