I believe it requires backporting these first.
commit 84158b7f6a06 ("coredump: Also dump first pages of non-executable ELF libraries") commit 95c5436a4883 ("coredump: Snapshot the vmas in do_coredump") commit 49c1866348f3 ("coredump: Remove the WARN_ON in dump_vma_snapshot")
The first is a more interesting bug fix from Jann Horn. The other two are prerequisite cleanup-patches.
Thanks, that worked!
I will let other folks judge how concerned they are about missing locking that was detected by code review.
locking where? And if it's not resolved in Linus's tree yet, not much I can do.
Also, what about for kernels older than 5.10? Is this an issue there?
thanks,
