It seems this PR sadly came too late for this week's net PR to mainline
that was merged yesterday.
TWIMC, from my point of view, it would be great if we somehow could
still get the changes from this PR or at least the btmtk fix it
contains[1] to mainline this week before -rc4, as it is fixing a
regression known since 2026-04-24 that at least five people encountered
with mainline since -rc3 due to 634a4408c0615c ("Bluetooth: btmtk:
validate WMT event SKB length before struct access") [006b9943b982 in
-next].
Another reason: Greg a few hours ago backported the culprit for the
regression to v7.0.7, v6.18.30, and v6.12.88, which led to a bunch of
other reports coming in[3]. Greg could, of course, revert it, but
usually he prefers to just merge the fix. But of course the fix must
first hit mainline (or at least -next) -- and that might only happen
next Thursday, as there usually is only one net PR per week. Luiz even
wanted to "expedite a PR to have it fixed asap"[4], but that didn't work
out afaics, hence this mail.
Ciao, Thorsten
