From 5e7d20ab1775e4c0416c9db243d25b22158701c6 Mon Sep 17 00:00:00 2001 From: Steve French Date: Tue, 20 May 2008 18:21:49 -0400 Subject: [PATCH] CIFS: Fix UNC path prefix on QueryUnixPathInfo to have correct slash upstream commit: 076d8423a98659a92837b07aa494cb74bfefe77c When a share was in DFS and the server was Unix/Linux, we were sending paths of the form \\server\share/dir/file rather than //server/share/dir/file There was some discussion between me and jra over whether we should use /server/share/dir/file as MS sometimes says - but the documentation for this claims it should be doubleslash for this type of UNC-like path format and that works, so leaving it as doubleslash but converting the \ to / in the the //server/share portion. This gets Samba to now correctly return STATUS_PATH_NOT_COVERED when it is supposed to (Windows already did since the direction of the slash was not an issue for them). Still need another minor change to fully enable DFS (need to finish some chages to SMBGetDFSRefer Signed-off-by: Steve French Signed-off-by: Chris Wright Signed-off-by: Greg Kroah-Hartman --- fs/cifs/inode.c | 15 +++++++++++---- 1 file changed, 11 insertions(+), 4 deletions(-) diff --git a/fs/cifs/inode.c b/fs/cifs/inode.c index bc673c8c1e6b..e1031b9e2c55 100644 --- a/fs/cifs/inode.c +++ b/fs/cifs/inode.c @@ -161,12 +161,14 @@ static void cifs_unix_info_to_inode(struct inode *inode, spin_unlock(&inode->i_lock); } -static const unsigned char *cifs_get_search_path(struct cifsTconInfo *pTcon, - const char *search_path) +static const unsigned char *cifs_get_search_path(struct cifs_sb_info *cifs_sb, + const char *search_path) { int tree_len; int path_len; + int i; char *tmp_path; + struct cifsTconInfo *pTcon = cifs_sb->tcon; if (!(pTcon->Flags & SMB_SHARE_IS_IN_DFS)) return search_path; @@ -180,6 +182,11 @@ static const unsigned char *cifs_get_search_path(struct cifsTconInfo *pTcon, return search_path; strncpy(tmp_path, pTcon->treeName, tree_len); + if (cifs_sb->mnt_cifs_flags & CIFS_MOUNT_POSIX_PATHS) + for (i = 0; i < tree_len; i++) { + if (tmp_path[i] == '\\') + tmp_path[i] = '/'; + } strncpy(tmp_path+tree_len, search_path, path_len); tmp_path[tree_len+path_len] = 0; return tmp_path; @@ -199,7 +206,7 @@ int cifs_get_inode_info_unix(struct inode **pinode, pTcon = cifs_sb->tcon; cFYI(1, ("Getting info on %s", search_path)); - full_path = cifs_get_search_path(pTcon, search_path); + full_path = cifs_get_search_path(cifs_sb, search_path); try_again_CIFSSMBUnixQPathInfo: /* could have done a find first instead but this returns more info */ @@ -402,7 +409,7 @@ int cifs_get_inode_info(struct inode **pinode, return -ENOMEM; pfindData = (FILE_ALL_INFO *)buf; - full_path = cifs_get_search_path(pTcon, search_path); + full_path = cifs_get_search_path(cifs_sb, search_path); try_again_CIFSSMBQPathInfo: /* could do find first instead but this returns more info */ -- 2.39.5
