I finally managed to reproduce the issue with 4.20-rc6, with KASAN enabled and
with CONFIG_SLUB_DEBUG_ON with SLAB_STORE_USER.
The following line indicates the crash happens when yavta PID 10289 tries to free the memory.
[ 452.437844] BUG: KASAN: use-after-free in ipu3_dmamap_free+0x50/0x9c [ipu3_imgu]
[ 452.446123] Read of size 8 at addr ffff8881503481a0 by task yavta/10289
The above looks to be normal, since it's the same task that allocated this memory.
[ 452.685731] Allocated by task 10289:
Before the above happened, yavta/10187 came in and freed this memory per KASAN.
[ 452.787656] Freed by task 10187:
Is this (one instance of yavta freeing the memory allocated by another instance of yavta) expected?
Or does it indicate that mmap giving the same address across these 2 instances of yavta?
I need to debug / confirm the latter case.
With the help of local application that operates these pipes in a serial fashion, I do not see
this issue.
I have pasted the relevant parts of the dmesg.
