[PATCH] block: allow for_each_bvec to support zero len bvec
by Yang Yingliang 29 Sep '20

29 Sep '20

From: Ming Lei <ming.lei(a)redhat.com> stable inclusion from linux-4.19.144 commit b48bcb664b657ae94b19c0728978c88e012f7a37 CVE: CVE-2020-25641 -------------------------------- commit 7e24969022cbd61ddc586f14824fc205661bb124 upstream. Block layer usually doesn't support or allow zero-length bvec. Since commit 1bdc76aea115 ("iov_iter: use bvec iterator to implement iterate_bvec()"), iterate_bvec() switches to bvec iterator. However, Al mentioned that 'Zero-length segments are not disallowed' in iov_iter. Fixes for_each_bvec() so that it can move on after seeing one zero length bvec. Fixes: 1bdc76aea115 ("iov_iter: use bvec iterator to implement iterate_bvec()") Reported-by: syzbot <syzbot+61acc40a49a3e46e25ea(a)syzkaller.appspotmail.com> Signed-off-by: Ming Lei <ming.lei(a)redhat.com> Tested-by: Tetsuo Handa <penguin-kernel(a)i-love.sakura.ne.jp> Cc: Al Viro <viro(a)zeniv.linux.org.uk> Cc: Matthew Wilcox <willy(a)infradead.org> Cc: <stable(a)vger.kernel.org> Link: https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg2262077.html Signed-off-by: Jens Axboe <axboe(a)kernel.dk> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Yang Yingliang <yangyingliang(a)huawei.com> Reviewed-by: Jason Yan <yanaijie(a)huawei.com> Signed-off-by: Yang Yingliang <yangyingliang(a)huawei.com> --- include/linux/bvec.h | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) diff --git a/include/linux/bvec.h b/include/linux/bvec.h index fe7a22dd133b..bc1f16e9f3f4 100644 --- a/include/linux/bvec.h +++ b/include/linux/bvec.h @@ -119,11 +119,18 @@ static inline bool bvec_iter_rewind(const struct bio_vec *bv, return true; } +static inline void bvec_iter_skip_zero_bvec(struct bvec_iter *iter) +{ + iter->bi_bvec_done = 0; + iter->bi_idx++; +} + #define for_each_bvec(bvl, bio_vec, iter, start) \ for (iter = (start); \ (iter).bi_size && \ ((bvl = bvec_iter_bvec((bio_vec), (iter))), 1); \ - bvec_iter_advance((bio_vec), &(iter), (bvl).bv_len)) + (bvl).bv_len ?
