From aa9be75d8a836106037389cb3d774d38d1397ea5 Mon Sep 17 00:00:00 2001 From: Volker Lendecke Date: Thu, 1 Jul 2004 14:49:44 +0000 Subject: r1314: Restore the 2.2 'force unknown acl user' parameter. When getting a security descriptor for a file, if the owner sid is not known, the owner uid is set to the current uid. Same for group sid. This makes xcopy /o possible for files that are owned by local users/groups (local administrators for example). Thanks to Guenther for his persistence :-) Volker (This used to be commit 80e57d27909a9a1edad962e3f43c2178d2da2a92) --- source3/smbd/posix_acls.c | 42 +++++++++++++++++++++++------------------- 1 file changed, 23 insertions(+), 19 deletions(-) (limited to 'source3/smbd/posix_acls.c') diff --git a/source3/smbd/posix_acls.c b/source3/smbd/posix_acls.c index 584164e930..2d9591e6ba 100644 --- a/source3/smbd/posix_acls.c +++ b/source3/smbd/posix_acls.c @@ -880,7 +880,7 @@ static mode_t map_nt_perms( SEC_ACCESS sec_access, int type) Unpack a SEC_DESC into a UNIX owner and group. ****************************************************************************/ -static BOOL unpack_nt_owners(SMB_STRUCT_STAT *psbuf, uid_t *puser, gid_t *pgrp, uint32 security_info_sent, SEC_DESC *psd) +static BOOL unpack_nt_owners(int snum, SMB_STRUCT_STAT *psbuf, uid_t *puser, gid_t *pgrp, uint32 security_info_sent, SEC_DESC *psd) { DOM_SID owner_sid; DOM_SID grp_sid; @@ -910,15 +910,17 @@ static BOOL unpack_nt_owners(SMB_STRUCT_STAT *psbuf, uid_t *puser, gid_t *pgrp, if (security_info_sent & OWNER_SECURITY_INFORMATION) { sid_copy(&owner_sid, psd->owner_sid); if (!NT_STATUS_IS_OK(sid_to_uid(&owner_sid, puser))) { -#if ACL_FORCE_UNMAPPABLE - /* this allows take ownership to work reasonably */ - extern struct current_user current_user; - *puser = current_user.uid; -#else - DEBUG(3,("unpack_nt_owners: unable to validate owner sid for %s\n", - sid_string_static(&owner_sid))); - return False; -#endif + if (lp_force_unknown_acl_user(snum)) { + /* this allows take ownership to work + * reasonably */ + extern struct current_user current_user; + *puser = current_user.uid; + } else { + DEBUG(3,("unpack_nt_owners: unable to validate" + " owner sid for %s\n", + sid_string_static(&owner_sid))); + return False; + } } } @@ -930,14 +932,16 @@ static BOOL unpack_nt_owners(SMB_STRUCT_STAT *psbuf, uid_t *puser, gid_t *pgrp, if (security_info_sent & GROUP_SECURITY_INFORMATION) { sid_copy(&grp_sid, psd->grp_sid); if (!NT_STATUS_IS_OK(sid_to_gid( &grp_sid, pgrp))) { -#if ACL_FORCE_UNMAPPABLE - /* this allows take group ownership to work reasonably */ - extern struct current_user current_user; - *pgrp = current_user.gid; -#else - DEBUG(3,("unpack_nt_owners: unable to validate group sid.\n")); - return False; -#endif + if (lp_force_unknown_acl_user(snum)) { + /* this allows take group ownership to work + * reasonably */ + extern struct current_user current_user; + *pgrp = current_user.gid; + } else { + DEBUG(3,("unpack_nt_owners: unable to validate" + " group sid.\n")); + return False; + } } } @@ -3005,7 +3009,7 @@ BOOL set_nt_acl(files_struct *fsp, uint32 security_info_sent, SEC_DESC *psd) * Unpack the user/group/world id's. */ - if (!unpack_nt_owners( &sbuf, &user, &grp, security_info_sent, psd)) + if (!unpack_nt_owners( SNUM(conn), &sbuf, &user, &grp, security_info_sent, psd)) return False; /* -- cgit
