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

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.

net: store KCOV remote handle in sk_buff
mac80211: add KCOV remote annotations to incoming frame processing
