Subject: Re: [PATCH] wifi: mt76: mt7921: skip unknown CLC firmware records
Date: Tue, 18 Aug 2026 01:16:56 +0500 [thread overview]
Message-ID: <20260817201656.1773758-1-mikhail.v.gavrilov@gmail.com> (raw)

Thanks for the quick turnaround.
Tested on an MT7922 (mt7921e) with linux-firmware 20260810 - the image
whose CLC region carries the idx 3 records - on a lockdep and UBSAN
build of mainline at fd923b32d761, with 9417c5818a01 applied underneath.
The device probes normally: the RAM firmware is loaded once rather than
ten times, wlp11s0 appears, association with a 6 GHz AP works (channel
37, 6135 MHz, 160 MHz), and switching between a 5 GHz and a 6 GHz BSS
and back is clean. No "hardware init failed", no "Invalid CLC record",
and no UBSAN report - so the bounds checks are still doing their job on
the very firmware that used to trip them.
Tested-by: Mikhail Gavrilov <mikhail.v.gavrilov@gmail.com>
One nit, take it or leave it: both length failures print the same
"Invalid CLC record", so the log does not distinguish a table that ends
mid-header from a record whose length is out of range. Two distinct
strings would make a future report easier to read.
