- Summary
- debugobjects: Don't wake up kswapd from fill_pool()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
debugobjects: Don't wake up kswapd from fill_pool()
syzbot is reporting a lockdep warning in fillpool() because the allocation from debugobjects is using GFPATOMIC, which is (__GFP_HIGH | _GFPKSWAPDRECLAIM) and therefore tries to wake up kswapd, which acquires kswapdwait::lock.
Since fillpool() might be called with arbitrary locks held, fillpool() should not assume that acquiring kswapd_wait::lock is safe.
Use __GFP_HIGH instead and remove __GFP_NORETRY as it is pointless for !__GFPDIRECTRECLAIM allocation.
