-
In the Linux kernel, the following vulnerability has been resolved:
zram: do not forget to endio for partial discard requests
As reported by Qu Wenruo and Avinesh Kumar, the following
getconf PAGESIZE 65536 blkdiscard -p 4k /dev/zram0
takes literally forever to complete. zram doesn't support partial discards and just returns immediately w/o doing any discard work in such cases. The problem is that we forget to endio on our way out, so blkdiscard sleeps forever in submitbiowait(). Fix this by jumping to endbio label, which does bioendio().
