SUNRPC: Move simple_get_bytes and simple_get_netobj into private header

2021-01-25T20:59:12+00:00

Remove duplicated helper functions to parse opaque XDR objects and place inside new file net/sunrpc/auth_gss/auth_gss_internal.h. In the new file carry the license and copyright from the source file net/sunrpc/auth_gss/auth_gss.c. Finally, update the comment inside include/linux/sunrpc/xdr.h since lockd is not the only user of struct xdr_netobj. Signed-off-by: Dave Wysochanski Signed-off-by: Trond Myklebust

SUNRPC: Cleanup - constify a number of xdr_buf helpers

2020-12-14T11:51:07+00:00

There are a number of xdr helpers for struct xdr_buf that do not change the structure itself. Mark those as taking const pointers for documentation purposes. Signed-off-by: Trond Myklebust

SUNRPC: Fix xdr_expand_hole()

2020-12-14T11:51:07+00:00

We do want to try to grow the buffer if possible, but if that attempt fails, we still want to move the data and truncate the XDR message. Signed-off-by: Trond Myklebust

SUNRPC: Fixes for xdr_align_data()

2020-12-14T11:51:07+00:00

The main use case right now for xdr_align_data() is to shift the page data to the left, and in practice shrink the total XDR data buffer. This patch ensures that we fix up the accounting for the buffer length as we shift that data around. Signed-off-by: Trond Myklebust

SUNRPC: xprt_load_transport() needs to support the netid "rdma6"

2020-12-02T19:05:52+00:00

According to RFC5666, the correct netid for an IPv6 addressed RDMA transport is "rdma6", which we've supported as a mount option since Linux-4.7. The problem is when we try to load the module "xprtrdma6", that will fail, since there is no modulealias of that name.
