From 8a430d74fea797fc55fef1ad4c21420212b83574 Mon Sep 17 00:00:00 2001 From: Evgeniy <dushistov@mail.ru> Date: Fri, 13 Jan 2006 18:12:15 +0300 Subject: [PATCH] [PATCH] Fix oops in ufs_fill_super at mount time There's a lack of parenthesis in fs/ufs/utils.h, so instead of the 512th byte of buffer, the usb2 pointer will point to the nth structure of type ufs_super_block_second. This can cause a mount-time oops if you're unlucky (especially with DEBUG_PAGEALLOC, which is how Alexey Dobriyan saw this problem) Signed-off-by: Evgeniy Dushistov <dushistov@mail.ru> Acked-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org> --- fs/ufs/util.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/fs/ufs/util.h b/fs/ufs/util.h index b2640076679a..e45ad5379872 100644 --- a/fs/ufs/util.h +++ b/fs/ufs/util.h @@ -255,8 +255,8 @@ extern void _ubh_memcpyubh_(struct ufs_sb_private_info *, struct ufs_buffer_head ((struct ufs_super_block_first *)((ubh)->bh[0]->b_data)) #define ubh_get_usb_second(ubh) \ - ((struct ufs_super_block_second *)(ubh)-> \ - bh[UFS_SECTOR_SIZE >> uspi->s_fshift]->b_data + (UFS_SECTOR_SIZE & ~uspi->s_fmask)) + ((struct ufs_super_block_second *)((ubh)->\ + bh[UFS_SECTOR_SIZE >> uspi->s_fshift]->b_data + (UFS_SECTOR_SIZE & ~uspi->s_fmask))) #define ubh_get_usb_third(ubh) \ ((struct ufs_super_block_third *)((ubh)-> \ -- 2.34.1
