Hi Eli,
have you already tried using kmemleak?
This sounds like a leak of memory allocated using kmalloc(), so kmemleak
should be able to catch it.
Hi Christian,
I have the following configured but I did not see any visible complaint
in dmesg.
CONFIG_HAVE_DEBUG_KMEMLEAK=y
CONFIG_DEBUG_KMEMLEAK=y
CONFIG_DEBUG_KMEMLEAK_MEM_POOL_SIZE=16000
Any other configuration that I need to set?
As long as you don't have any kernel parameters to enable it I think you
need to do "echo scan > /sys/kernel/debug/kmemleak" to start a scan.
The result can then be queried using "cat /sys/kernel/debug/kmemleak".
Regards,
Christian.
