Later this may be worked out. - -Use "simple" mode when the share is used mainly by windows users and unix side is not significant. You will loose unix bits in this case. -It's strongly advised setting "store dos attributes = yes" in smb.conf. - -chown = [true|false] -- true => enable changing owner and group - default. -- false => disable support for changing owner or group - -acedup = [dontcare|reject|ignore|merge] -- dontcare: copy ACEs as they come, don't care with "duplicate" records. Default. -- reject: stop operation, exit acl setter operation with an error -- ignore: don't include the second matching ACE -- merge: OR 2 ace.flag fields and 2 ace.mask fields of the 2 duplicate ACEs into 1 ACE - -Two ACEs are considered here "duplicate" when their type and id fields are matching. - -Example: - -[smbtest] -path = /tests/psomogyi/smbtest -writable = yes -vfs objects = aixacl2 -nfs4: mode = special -nfs4: chown = yes -nfs4: acedup = merge - -Configuring AIX ACL support -============================== - -Binaries: (default install path is [samba]/lib/vfs/) -- aixacl.so: provides AIXC ACL support only, can be compiled and works on all AIX platforms -- aixacl2.so: provides AIXC and JFS2-NFS4 ACL support, can be compiled and works only under AIX 5.3 and newer. -NFS4 acl currently has support only under JFS2 (ext. attr. format must be set to v2). -aixacl2.so always detects support for NFS4 acls and redirects to POSIX ACL handling automatically when NFS4 is not supported for a path. - -Adding "vfs objects = aixacl2" to a share should be done only in case when NFS4 is really supported by the filesystem. -(Otherwise you may get performance loss.) - -For configuration see also the example above. - -General notes -============= - -NFS4 handling logic is separated from AIX/jfs2 ACL parsing. - -Samba and its VFS modules dosn't reorder ACEs. Windows clients do that (and the smbcacl tool). MSDN also says deny ACEs must come first. -NFS4 ACL's validity is checked by the system API, not by Samba. -NFS4 ACL rights are enforced by the OS or filesystem, not by Samba. - -The flag INHERITED_ACE is never set (not required, as doesn't do WinNT/98/me, only since Win2k). -Win2k GUI behaves strangely when detecting inheritance (sometimes it doesn't detect, -but after adding an ace it shows that - it's some GUI error). - -Unknown (unmappable) SIDs are not accepted. - -TODOs -===== -- Creator Owner & Group SID handling (same way as posix) -- the 4 generic rights bits support (GENERIC_RIGHT_READ_ACCESS, WRITE, EXEC, ALL) -- chown & no ACL, but we have ONWER@ and GROUP@ -- DIALUP, ANONYMOUS, ... builtin SIDs -- audit & alarm support - in theory it's forwarded so it should work, but currently there's no platform which supports them to test -- support for a real NFS4 client (we don't have an accepted API yet) diff --git a/source3/Makefile.in b/source3/Makefile.in index 9a4b9c6518..0ff5872063 100644 --- a/source3/Makefile.in +++ b/source3/Makefile.in @@ -384,7 +384,6 @@ VFS_SHADOW_COPY_OBJ = modules/vfs_shadow_copy.o VFS_AFSACL_OBJ = modules/vfs_afsacl.o VFS_POSIXACL_OBJ = modules/vfs_posixacl.o VFS_AIXACL_OBJ = modules/vfs_aixacl.o modules/vfs_aixacl_util.o -VFS_AIXACL2_OBJ = modules/vfs_aixacl2.o modules/vfs_aixacl_util.o modules/nfs4_acls.o VFS_SOLARISACL_OBJ = modules/vfs_solarisacl.o VFS_HPUXACL_OBJ = modules/vfs_hpuxacl.o VFS_IRIXACL_OBJ = modules/vfs_irixacl.o @@ -1370,11 +1369,6 @@ bin/aixacl.@SHLIBEXT@: $(VFS_AIXACL_OBJ:.o=.@PICSUFFIX@) @$(SHLD) $(LDSHFLAGS) -o $@ $(VFS_AIXACL_OBJ:.o=.@PICSUFFIX@) \ @SONAMEFLAG@`basename $@` -bin/aixacl2.@SHLIBEXT@: $(VFS_AIXACL2_OBJ:.o=.@PICSUFFIX@) - @echo "Building plugin $@" - @$(SHLD) $(LDSHFLAGS) -o $@ $(VFS_AIXACL2_OBJ:.o=.@PICSUFFIX@) \ - @SONAMEFLAG@`basename $@` - bin/solarisacl.@SHLIBEXT@: $(VFS_SOLARISACL_OBJ:.o=.@PICSUFFIX@) @echo "Building plugin $@" @$(SHLD) $(LDSHFLAGS) -o $@ $(VFS_SOLARISACL_OBJ:.o=.@PICSUFFIX@) \ diff --git a/source3/configure.in b/source3/configure.in index 02af9995fb..c84312f32a 100644 --- a/source3/configure.in +++ b/source3/configure.in @@ -5592,7 +5592,6 @@ SMB_MODULE(vfs_shadow_copy, \$(VFS_SHADOW_COPY_OBJ), "bin/shadow_copy.$SHLIBEXT" SMB_MODULE(vfs_afsacl, \$(VFS_AFSACL_OBJ), "bin/afsacl.$SHLIBEXT", VFS) SMB_MODULE(vfs_posixacl, \$(VFS_POSIXACL_OBJ), "bin/posixacl.$SHLIBEXT", VFS) SMB_MODULE(vfs_aixacl, \$(VFS_AIXACL_OBJ), "bin/aixacl.$SHLIBEXT", VFS) -SMB_MODULE(vfs_aixacl2, \$(VFS_AIXACL2_OBJ), "bin/aixacl2.$SHLIBEXT", VFS) SMB_MODULE(vfs_solarisacl, \$(VFS_SOLARISACL_OBJ), "bin/solarisacl.$SHLIBEXT", VFS) SMB_MODULE(vfs_irixacl, \$(VFS_IRIXACL_OBJ), "bin/irixacl.$SHLIBEXT", VFS) SMB_MODULE(vfs_hpuxacl, \$(VFS_HPUXACL_OBJ), "bin/hpuxacl.$SHLIBEXT", VFS) diff --git a/source3/modules/nfs4_acls.c b/source3/modules/nfs4_acls.c deleted file mode 100644 index 795afee45a..0000000000 --- a/source3/modules/nfs4_acls.c +++ /dev/null @@ -1,668 +0,0 @@ -/* - * NFS4 ACL handling - * - * Copyright (C) Jim McDonough, 2006 - * Major code contributions from Peter Somogyi, somogyi@de.ibm.com - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
