From: Andy Adamson Date: Wed, 7 Dec 2011 16:55:27 +0000 (-0500) Subject: NFSv4: include bitmap in nfsv4 get acl data X-Git-Tag: v3.2.2~105 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=628fc192adbaae0c6178b9015fb916ce61d72b36;p=pandora-kernel.git NFSv4: include bitmap in nfsv4 get acl data commit bf118a342f10dafe44b14451a1392c3254629a1f upstream. The NFSv4 bitmap size is unbounded: a server can return an arbitrary sized bitmap in an FATTR4_WORD0_ACL request. Replace using the nfs4_fattr_bitmap_maxsz as a guess to the maximum bitmask returned by a server with the inclusion of the bitmap (xdr length plus bitmasks) and the acl data xdr length to the (cached) acl page data. This is a general solution to commit e5012d1f "NFSv4.1: update nfs4_fattr_bitmap_maxsz" and fixes hitting a BUG_ON in xdr_shrink_bufhead when getting ACLs. Fix a bug in decode_getacl that returned -EINVAL on ACLs > page when getxattr was called with a NULL buffer, preventing ACL > PAGE_SIZE from being retrieved.
