Subject: size limit of extended attributes
Date: Thu, 30 Apr 2015 13:33:02 +0200	[thread overview]
Message-ID: <E1YnnD9-001QBR-Vf@intern.SerNet.DE> (raw)

Hi,

currently there is the hard limit for the size of extended attributes, of
XATTR_SIZE_MAX set to 65536.

Is there a reason for that limit or can this limit be removed, so that only the
filesystem stays as a limiting factor here?

In Samba we need to be able to store data in extrended attributes which can be
much biger thatn 64k. AIX for example supports EAs of 16TB size in JFS2,
Solaris is able to handle streams like files and also doesn't have special size
limitations for EAs. Can we get rid of the tiny size limit in Linux also?

Björn
