If the fragment is discarded in mt76_add_fragment() since shared_info
frag array is full, discard truncated frames and do not forward them to
mac80211.

Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org>

Should there be a Fixes line? I can add it.

I am not sure it needs a Fixes tag.

I think the commit log should have some kind of description about the
background of the issue, for example if this is a recent regression or
has been there forever etc.

Agree. Can you please check the commit log below?

"
Commit 'b102f0c522cf6 ("mt76: fix array overflow on receiving too many
fragments for a packet")' fixes a possible OOB access but it introduces a
memory leak since the pending frame is not released to page_frag_cache if
the frag array of skb_shared_info is full.
Commit '93a1d4791c10 ("mt76: dma: fix a possible memory leak in
mt76_add_fragment()")' fixes the issue but does not free the truncated skb that
is forwarded to mac80211 layer. Fix the leftover issue discarding even truncated
skbs.

Looks good, but I think the recommended style for commit ids is not to
use ' chararacter. So I would change it to this:

----------------------------------------------------------------------

Should I add that to the commit log and queue the patch to be applied
after the merge window opens?
