Subject: commit 1c29a32ce65f4cd0f1c causes Bad rss-counter state and firefox-esr crash in linux-next-20240613
Date: Fri, 14 Jun 2024 01:40:54 +0200 [thread overview]
Message-ID: <f4ea65e28ac47e6acb13f401f46a414a2f50f7bf.camel@web.de> (raw)
Since linux-next-20240613 firefox-esr crashes after several minutes of browsing
giving the following error messages in dmesg:
[ T2343] BUG: Bad rss-counter state mm:00000000babe0c39 type:MM_ANONPAGES val:86
[ T4063] show_signal_msg: 16 callbacks suppressed
[ T4063] Isolated Web Co[4063]: segfault at 396d1686c000 ip 0000396d1686c000 sp

[ T1] BUG: Bad rss-counter state mm:000000005e5e2f2f type:MM_ANONPAGES val:28
(these are the error messages of several crashes and the error seems to affect
other processes, too (T1))
The crash can be provoked to appear in ~1min by opening large numbers of tabs in
firefox-esr (by holding pressing ctrl+t for some time). With this I bisected the
error to commit "1c29a32ce65f mm/mmap: use split munmap calls for MAP_FIXED" and
reverting this commit in linux-next-20240613 fixes the issue for me.
