Subject: [PATCH 0/2] net, mac80211: enable KCOV remote coverage collection for 802.11 frame handling

From: Aleksandr Nogikh <nogikh@...gle.com>

This patch series enables remote KCOV coverage collection for the
mac80211 code that processes incoming 802.11 frames. These changes
make it possible to perform coverage-guided fuzzing in search of
remotely triggerable bugs.

The series consists of two commits.
1. Remember kcov_handle for each sk_buff. This can later be used to
enable remote coverage for other network subsystems.
2. Annotate the code that processes incoming 802.11 frames.

Aleksandr Nogikh (2):
  net: store KCOV remote handle in sk_buff
  mac80211: add KCOV remote annotations to incoming frame processing
