From ca76d2d8031fd8216eedadee77dfe009a63e4408 Mon Sep 17 00:00:00 2001 From: Cyrill Gorcunov Date: Tue, 31 Jul 2007 00:39:40 -0700 Subject: UDF: fix UID and GID mount option ignorance This patch fix weird behaviour of UDF mounting procedure. To get UID changed (for now) we have to type mount -t udf -o uid=some_user,uid=ignore /dev/device /mnt/moun_point and specifying two uid at once is strange a bit. So with the patch we are able to mount without additional 'uid=ignore' option. The same for GID option is done. This patch will not break current mount scheme (with two option). Btw this does fix (I hope) the following [BUG 6124] mount of UDF fs ignores UID and GID options http://bugzilla.kernel.org/show_bug.cgi?id=6124 Signed-off-by: Cyrill Gorcunov Cc: Jan Kara Cc: Michael Cc: Eric Sandeen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/udf/inode.c | 10 ++++++---- fs/udf/super.c | 2 ++ fs/udf/udf_sb.h | 2 ++ 3 files changed, 10 insertions(+), 4 deletions(-) (limited to 'fs/udf') diff --git a/fs/udf/inode.c b/fs/udf/inode.c index 0d2c41666cd2..1652b2c665bb 100644 --- a/fs/udf/inode.c +++ b/fs/udf/inode.c @@ -1127,13 +1127,15 @@ static void udf_fill_inode(struct inode *inode, struct buffer_head *bh) } inode->i_uid = le32_to_cpu(fe->uid); - if (inode->i_uid == -1 || UDF_QUERY_FLAG(inode->i_sb, - UDF_FLAG_UID_IGNORE)) + if (inode->i_uid == -1 || + UDF_QUERY_FLAG(inode->i_sb, UDF_FLAG_UID_IGNORE) || + UDF_QUERY_FLAG(inode->i_sb, UDF_FLAG_UID_SET)) inode->i_uid = UDF_SB(inode->i_sb)->s_uid; inode->i_gid = le32_to_cpu(fe->gid); - if (inode->i_gid == -1 || UDF_QUERY_FLAG(inode->i_sb, - UDF_FLAG_GID_IGNORE)) + if (inode->i_gid == -1 || + UDF_QUERY_FLAG(inode->i_sb, UDF_FLAG_GID_IGNORE) || + UDF_QUERY_FLAG(inode->i_sb, UDF_FLAG_GID_SET)) inode->i_gid = UDF_SB(inode->i_sb)->s_gid; inode->i_nlink = le16_to_cpu(fe->fileLinkCount); diff --git a/fs/udf/super.c b/fs/udf/super.c index 7b30964665db..382be7be5ae3 100644 --- a/fs/udf/super.c +++ b/fs/udf/super.c @@ -366,11 +366,13 @@ static int udf_parse_options(char *options, struct udf_options *uopt) if (match_int(args, &option)) return 0; uopt->gid = option; + uopt->flags |= (1 << UDF_FLAG_GID_SET); break; case Opt_uid: if (match_int(args, &option)) return 0; uopt->uid = option; + uopt->flags |= (1 << UDF_FLAG_UID_SET); break; case Opt_umask: if (match_octal(args, &option)) diff --git a/fs/udf/udf_sb.h b/fs/udf/udf_sb.h index 3e937d3fb8f9..3c2982017c6d 100644 --- a/fs/udf/udf_sb.h +++ b/fs/udf/udf_sb.h @@ -24,6 +24,8 @@ #define UDF_FLAG_UID_IGNORE 12 /* use sb uid instead of on disk uid */ #define UDF_FLAG_GID_FORGET 13 #define UDF_FLAG_GID_IGNORE 14 +#define UDF_FLAG_UID_SET 15 +#define UDF_FLAG_GID_SET 16 #define UDF_PART_FLAG_UNALLOC_BITMAP 0x0001 #define UDF_PART_FLAG_UNALLOC_TABLE 0x0002 -- cgit v1.2.3
