File reiserfsprogs-fsck-mapid.diff of Package reiserfs
From: Jeff Mahoney <jeffm@suse.com> Subject: [PATCH] reiserfsprogs: id_map_init off-by-one The following patch fixes a bug where reiserfsck will crash if OIDs up around the maximum are in use. The problem is that INDEX_COUNT ends up rounding down and the last chunk isn't allocated, causing a segfault. --- fsck/uobjectid.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/fsck/uobjectid.c 2004-06-17 15:57:39.000000000 -0400 +++ b/fsck/uobjectid.c 2008-01-24 13:39:04.000000000 -0500 @@ -15,7 +15,7 @@ /* 2 bytes for the counter */ #define BM_SIZE (ALLOC_SIZE - sizeof(__u16)) #define BM_INTERVAL (BM_SIZE * 8) -#define INDEX_COUNT (MAX_ID / BM_INTERVAL) +#define INDEX_COUNT ((MAX_ID / BM_INTERVAL) + 1) #define id_map_interval(map, id) (map->index + (id / BM_INTERVAL))
