SUNRPC: xdr_read_pages should return the amount of XDR encoded page data

2012-06-28T21:20:43+00:00

Callers of xdr_read_pages() will want to know exactly how much XDR data is encoded in the pages after the data realignment. Signed-off-by: Trond Myklebust

SUNRPC: Don't decode beyond the end of the RPC reply message

2012-06-28T21:20:41+00:00

Now that xdr_inline_decode() will automatically cross into the page buffers, we need to ensure that it doesn't exceed the total reply message length. This patch sets up a counter that tracks the number of words remaining in the reply message, and ensures that xdr_inline_decode, xdr_read_pages and xdr_enter_page respect the end of message boundary.

NFSv4: include bitmap in nfsv4 get acl data

2012-01-05T15:42:42+00:00

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.

NFS: Don't use vm_map_ram() in readdir

2011-01-10T19:45:01+00:00

vm_map_ram() is not available on NOMMU platforms, and causes trouble on incoherrent architectures such as ARM when we access the page data through both the direct and the virtual mapping. The alternative is to use the direct mapping to access page data for the case when we are not crossing a page boundary, but to copy the data into a linear scratch buffer when we are accessing data that spans page boundaries.

SUNRPC: New xdr_streams XDR decoder API

2010-12-16T17:37:25+00:00

Now that all client-side XDR decoder routines use xdr_streams, there should be no need to support the legacy calling sequence [rpc_rqst *, __be32 *, RPC res *] anywhere. We can construct an xdr_stream in the generic RPC code, instead of in each decoder function. This is a refactoring change. It should not cause different behavior.

SUNRPC: New xdr_streams XDR encoder API

2010-12-16T17:37:25+00:00

Now that all client-side XDR encoder routines use xdr_streams, there should be no need to support the legacy calling sequence [rpc_rqst *, __be32 *, RPC arg *] anywhere. We can construct an xdr_stream in the generic RPC code, instead of in each encoder function. Also, all the client-side encoder functions return 0 now, making a return value superfluous. Take this opportunity to convert them to return void instead. This is a refactoring change. It should not cause different behavior. Signed-off-by: Chuck Lever Tested-by: J.
