If anyone has any objections, please let me know. ------------------ From: Steve French commit b1d93356427be6f050dc55c86eb019d173700af6 upstream. setfacl over cifs mounts can remove the default ACL when setting the (non-default part of) the ACL and vice versa (we were leaving at 0 rather than setting to -1 the count field for the unaffected half of the ACL. For example notice the setfacl removed the default ACL in this sequence: steven@steven-GA-970A-DS3:~/cifs-2.6$ getfacl /mnt/test-dir ; setfacl -m default:user:test:rwx,user:test:rwx /mnt/test-dir getfacl: Removing leading '/' from absolute path names user::rwx group::r-x other::r-x default:user::rwx default:user:test:rwx default:group::r-x default:mask::rwx default:other::r-x steven@steven-GA-970A-DS3:~/cifs-2.6$ getfacl /mnt/test-dir getfacl: Removing leading '/' from absolute path names user::rwx user:test:rwx group::r-x mask::rwx other::r-x Signed-off-by: Steve French Acked-by: Jeremy Allison Signed-off-by: Luis Henriques --- fs/cifs/cifssmb.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/fs/cifs/cifssmb.c b/fs/cifs/cifssmb.c index a89c4cb..18028c8 100644 --- a/fs/cifs/cifssmb.c +++ b/fs/cifs/cifssmb.c @@ -3296,11 +3296,13 @@ static __u16 ACL_to_cifs_posix(char *parm_data, const char *pACL, return 0; } cifs_acl->version = cpu_to_le16(1); - if (acl_type == ACL_TYPE_ACCESS) + if (acl_type == ACL_TYPE_ACCESS) { cifs_acl->access_entry_count = cpu_to_le16(count); - else if (acl_type == ACL_TYPE_DEFAULT) + cifs_acl->default_entry_count = __constant_cpu_to_le16(0xFFFF); + } else if (acl_type == ACL_TYPE_DEFAULT) { cifs_acl->default_entry_count = cpu_to_le16(count); - else { + cifs_acl->access_entry_count = __constant_cpu_to_le16(0xFFFF); + } else { cifs_dbg(FYI, "unknown ACL type %d\n", acl_type); return 0; } -- 1.8.3.2
