Subject: regression in iwlwifi: page fault in iwl_dbg_tlv_alloc_region() (commit ba8f6f4ae254)
Date: Mon, 28 Dec 2020 12:58:14 +0100 [thread overview]
Message-ID: <20201228115814.GA5880@lion.mk-sys.cz> (raw)
FYI, there is a regression in iwlwifi driver caused by commit
ba8f6f4ae254 ("iwlwifi: dbg: add dumping special device memory")
reported at
https://bugzilla.kernel.org/show_bug.cgi?id=210733
https://bugzilla.suse.com/show_bug.cgi?id=1180344
The problem seems to be an attempt to write terminating null character
into a string which may be read only. There is also a proposed fix.
Michal
