Lizhi Xu f5c84eff63 loop: Add sanity check for read/write_iter ... Some file systems do not support read_iter/write_iter, such as selinuxfs in this issue. So before calling them, first confirm that the interface is supported and then call it. It is releavant in that vfs_iter_read/write have the check, and removal of their used caused szybot to be able to hit this issue. Fixes: f2fed441c6 ("loop: stop using vfs_iter__{read,write} for buffered I/O") Reported-by: syzbot+6af973a3b8dfd2faefdc@syzkaller.appspotmail.com Closes: https://syzkaller.appspot.com/bug?extid=6af973a3b8dfd2faefdc Signed-off-by: Lizhi Xu <lizhi.xu@windriver.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Link: https://lore.kernel.org/r/20250428143626.3318717-1-lizhi.xu@windriver.com Signed-off-by: Jens Axboe <axboe@kernel.dk>		2025-05-05 07:18:05 -06:00
