Subject: Memory corruption (redzone overwritten) names_cache?
Hi,
We're getting some random memory corruption on an AWS EC2 instance with
4.19.x kernels. I've tried 4.19.19, 4.19.52, but the results below are
from the most recent (4.19.72). For debugging I enabled
KASAN+slub_debug, but TBH, I can't make heads or tails from these.
Without slub_debug, the host reboots within couple of minutes of uptime.
With slub_debug it survives a bit longer, but eventually all sorts of
issues manifest (including: reboot; ps not being able to read some
processes' /proc/<pid>/cmdline while /proc/<pid>/stack shows
acct_collect()->down_read(), etc).
Upon multiple tests, the slab I most often seen pop up as first detected
as corrupted was names_cache.
What is really weird is that multiple times I saw redzone being
overwritten by the same content, which looks like part of 'sessions.py'
Python's 'requests' module.
Any debugging hints would be greatly appreciated.
Command line: BOOT_IMAGE=(hd0,msdos2)/vmlinuz ro root=/dev/xvda5 console=tty0 console=ttyS0,9600n8 crashkernel=512M-2G:64M,2G-:128M kmemleak=on slub_debug=FZPU slub_nomerge
