Details
In the Linux kernel, the following vulnerability has been resolved:
Revert "md/raid5: Wait for MD_SB_CHANGE_PENDING in raid5d"
This reverts commit 5e2cf333b7bd5d3e62595a44d598a254c697cd74.
That commit introduced the following race and can cause system hung.
md_write_start: raid5d:
// mddev->in_sync == 1
set "MD_SB_CHANGE_PENDING"
// running before md_write_start wakeup it
waiting "MD_SB_CHANGE_PENDING" cleared
>>>>>>>>> hung
wakeup mddev->thread
...
waiting "MD_SB_CHANGE_PENDING" cleared
>>>> hung, raid5d should clear this flag
but get hung by same flag.
The issue reverted commit fixing is fixed by last patch in a new way.
