this is filed in the acl tracker, so close this (since it's an issue with the acl package, not attr)

Summary: Path length limit in setfacl ACL utility for Unicode
Product: XFS
Version: Current
Platform: All
OS/Version: All
Status: NEW
Severity: minor

In read_acl_comments() function of the setfacl/parse.c file linebuf variable is
limited to 1024 characters. As I have learned in the process of importing ACLs
from our server, that's not enough for Unicode paths on the production file
server using file names with Unicode.

While "getfacl -R" returns correct file of ACLs, "setfacl --restore" says
"invalid argument near line XYZ" on lines with long Unicode paths. Changing
"linebuf[1024]" to "linebuf[2048]" in setfacl/parse.c solved my problem.

An example of ACL entry that setfacl couldn't take care of because of 1024
limit is as following:

# file:
# owner: root
# group: users

Our server is running Gentoo Linux with Linux kernel 2.6.28 and acl v2.2.47
from Gentoo portage.
