[SRU] Xenial
Getting -EINVAL on stressors that call clone() on aarch64. Turns out that the clone() thread's stack has to be 16 byte aligned.
[REPODUCER + FIX]
For example, run:
stress-ng --vm-rw 1 -v
Without the fix, this can randomly exit with -EINVAL when the stack being passed to the clone() system call is not aligned on a 16 byte boundary.
With the fix, the clone() system call works fine and the stressor will run.
[REGRESSION POTENIAL]
Minimal. I have exhaustively tested this on multiple platforms/architectures and the fix ensures that the stack is aligned correctly. stress-ng is a leaf project in universe and this fix only touches 3 of the stress-ng stressors that use the clone() system call. |
