Subject: [Acl-Devel] Version 0.7.23 released
Date:	 Fri, 9 Nov 2001 04:46:49 +0100 (CET)

Hello,

the most important news first: After a very long time, we have a backup
utility that supports Access Control Lists. J"org Schilling
<schilling@fokus.gmd.de> has added Access Control List support to his
tar/pax clone called Star. Read more about this on our Web site,
<http://acl/bestbits.at/>.

We also have another version of Extended Attributes and Access Control
Lists. Despite my previous announcement this version still uses the same
system call interface as previous versions.

This time a few minor issues were fixed, and the new ext3 support has been
further improved. The system call numbers for the PowerPC architecture
have changed.

An old bug was fixed in the fileutils patch, and some minor corrections
have been made to the acl_to_text() and acl_from_text() functions in the
ACL library.

Here are the relevant entries from the change log:


Known bugs
----------
 * The ext3 extended attribute or ACL code interacts badly with the ext3
   quota code. The system crashes under heavy load if all the following
   conditions are met: (a) extended attributes and/or ACLs are used,
   (b) quota are used, and (c) the system is a multi-processer machine.
   It is not clear yet excatly what causes the problems.

 * If a quota limit is reached, extended attributes cannot be modified
   anymore, even if that would not change the quota. Internally this
   counts as creating a new block, and then freeing the old block, which
   is denied by the quota code.

0.7.23
------
Kernel patches:
 * Removed some extra checking code
 * Marks a filesystem bad if I/O errors occur or the on-disk extended
   attribute format is corrupted.
 * The syscall numbers for the PPC architecture have changed.

Ext3 support in the kernel:
 * Some cleanups in ext3_set_ext_attr
 * Ext3: adjusted the required free journal space before an EA operation
   is allowed to start to account for EA blocks.
 * Ext3: EA blocks are now poisoned when the reference count drops to 0.

Fileutils patch:
 * Some cleanups in Autoconf.
 * The permissions (ACLs and mode bits) were sometimes wrongly copied.
 * Permissions of parent directories (cp `--parents' option) are now also
   copied when they should be.

ACL utilities:
 * acl_to_text() wrongly terminated the text representation with a
   double-newline.
 * acl_from_text() only recognized the short text form, and did not
   recognize the long text form as well.


Regards,
Andreas.
