From 5391b8e1b7b7e5cfa2dd4ffdc4b8c6b64dfd1866 Mon Sep 17 00:00:00 2001 From: Paul Aurich Date: Fri, 26 Jun 2020 12:58:09 -0700 Subject: [PATCH] SMB3: Honor 'posix' flag for multiuser mounts The flag from the primary tcon needs to be copied into the volume info so that cifs_get_tcon will try to enable extensions on the per-user tcon. At that point, since posix extensions must have already been enabled on the superblock, don't try to needlessly adjust the mount flags. Fixes: ce558b0e17f8 ("smb3: Add posix create context for smb3.11 posix mounts") Fixes: b326614ea215 ("smb3: allow "posix" mount option to enable new SMB311 protocol extensions") Signed-off-by: Paul Aurich Signed-off-by: Steve French Reviewed-by: Aurelien Aptel --- fs/cifs/connect.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/fs/cifs/connect.c b/fs/cifs/connect.c index dada6d5..a61abde 100644 --- a/fs/cifs/connect.c +++ b/fs/cifs/connect.c @@ -5311,6 +5311,7 @@ cifs_construct_tcon(struct cifs_sb_info *cifs_sb, kuid_t fsuid) vol_info->persistent = master_tcon->use_persistent; vol_info->handle_timeout = master_tcon->handle_timeout; vol_info->no_linux_ext = !master_tcon->unix_ext; + vol_info->linux_ext = master_tcon->posix_extensions; vol_info->sectype = master_tcon->ses->sectype; vol_info->sign = master_tcon->ses->sign; vol_info->seal = master_tcon->seal; @@ -5339,10 +5340,6 @@ cifs_construct_tcon(struct cifs_sb_info *cifs_sb, kuid_t fsuid) goto out; } - /* if new SMB3.11 POSIX extensions are supported do not remap / and \ */ - if (tcon->posix_extensions) - cifs_sb->mnt_cifs_flags |= CIFS_MOUNT_POSIX_PATHS; - if (cap_unix(ses)) reset_cifs_unix_caps(0, tcon, NULL, vol_info); -- 2.7.4
