* Reapply POSIX ACL changes.Corinna Vinschen2015-11-1813-1118/+1347
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - New, unified implementation of POSIX permission and ACL handling. The new ACLs now store the POSIX ACL MASK/CLASS_OBJ permission mask, and they allow to inherit the S_ISGID bit. ACL inheritance now really works as desired, in a limited, but theoretically equivalent fashion even for non-Cygwin processes. To accommodate Windows default ACLs, the new code ignores SYSTEM and Administrators group permissions when computing the MASK/CLASS_OBJ permission mask on old ACLs, and it doesn't deny access to SYSTEM and Administrators group based on the value of MASK/CLASS_OBJ when creating the new ACLs. The new code now handles the S_ISGID bit on directories as on Linux: Setting S_ISGID on a directory causes new files and subdirs created within to inherit its group, rather than the primary group of the user who created the file. This only works for files and directories created by Cygwin processes. 2015-05-29 Corinna Vinschen <corinna@vinschen.de> Reapply POSIX ACL changes. * utils.xml (setfacl): Show new option output. (getfacl): Show new option output. * sec_acl.cc (get_posix_access): Check for Cygwin "standard" ACL. Apply umask, if so.

(fhandler_pty_slave::fchown): Fix uid/gid handling. * sec_acl.cc (set_posix_access): Drop superfluous class_idx variable. Simplify and move around code in a few places.

(get_posix_access): Fake CLASS_OBJ for ptys. Explain why. * security.cc (get_object_attribute): Add S_IFCHR flag to attributes when calling get_posix_access. * sec_acl.cc (set_posix_access): Move merging group perms into owner perms in case of owner == group after mask has been computed. Take mask into account when doing so to avoid unnecessary ACCESS_DENIED_ACE. * sec_acl.cc (get_posix_access): Only set saw_group_obj flag if we saw the ACCESS_ALLOWED_ACE. * fhandler_disk_file.cc (fhandler_disk_file::fchmod): Deliberatly set GROUP_OBJ and CLASS_OBJ perms to new group perms.
