http://gitweb.samba.org/?p=samba.git;a=shortlog;h=v3-3-test - Log ----------------------------------------------------------------- commit 9bd957580360ed7a0f98b02d1e03d7fcaf8a878e Author: Jeremy Allison <j...@samba.org> Date: Fri Jan 8 10:24:34 2010 -0800 Re-fix bug 5202 - cannot change ACLs on writable file with "dos filemode=yes" This bug re-occurred for 3.3.x and above. The reason is that to change a NT ACL we now have to open the file requesting WRITE_DAC and WRITE_OWNER access. The mapping from POSIX "w" to NT permissions in posix_acls doesn't add these bits when "dos filemode = yes", so even though the permission or owner change would be allowed by the POSIX ACL code, the NTCreateX call fails with ACCESS_DENIED now we always check NT permissions first. Added in the mapping from "w" to WRITE_DAC and WRITE_OWNER access.
