SUNRPC: Fix potential memory corruption

2021-09-18T11:40:13Z

[ Upstream commit c2dc3e5fad13aca5d7bdf4bcb52b1a1d707c8555 ] We really should not call rpc_wake_up_queued_task_set_status() with xprt->snd_task as an argument unless we are certain that is actually an rpc_task.

SUNRPC: More fixes for backlog congestion

2021-06-03T07:00:51Z

commit e86be3a04bc4aeaf12f93af35f08f8d4385bcd98 upstream. Ensure that we fix the XPRT_CONGESTED starvation issue for RDMA as well as socket based transports. Ensure we always initialise the request after waking up from the backlog list. Fixes: e877a88d1f06 ("SUNRPC in case of backlog, hand free slots directly to waiting task") Signed-off-by: Trond Myklebust Signed-off-by: Greg Kroah-Hartman

SUNRPC: Move simple_get_bytes and simple_get_netobj into private header

2021-02-13T12:55:12Z

[ Upstream commit ba6dfce47c4d002d96cd02a304132fca76981172 ] 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.

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

2020-12-30T10:53:30Z

[ Upstream commit d5aa6b22e2258f05317313ecc02efbb988ed6d38 ] 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.

SUNRPC: Add an xdr_align_data() function

2020-10-07T18:28:40Z

For now, this function simply aligns the data at the beginning of the pages. This can eventually be expanded to shift data to the correct offsets when we're ready. Signed-off-by: Anna Schumaker

SUNRPC: Add the ability to expand holes in data pages

2020-10-07T18:28:39Z

This patch adds the ability to "read a hole" into a set of XDR data pages by taking the following steps: 1) Shift all data after the current xdr->p to the right, possibly into the tail, 2) Zero the specified range, and 3) Update xdr->p to point beyond the hole. Signed-off-by: Anna Schumaker

SUNRPC: Implement a xdr_page_pos() function

2020-10-07T18:28:39Z

I'll need this for READ_PLUS to help figure out the offset where page data is stored at, but it might also be useful for other things. Signed-off-by: Anna Schumaker
