SUNRPC: Fix oops in the rpc_xdr_buf event class

2020-11-24T12:39:00Z

[ Upstream commit c3213d260a23e263ef85ba21ac68c9e7578020b5 ] Backchannel rpc tasks don't have task->tk_client set, so it's necessary to check it for NULL before dereferencing.

SUNRPC: Fix general protection fault in trace_rpc_xdr_overflow()

2020-11-18T18:22:17Z

[ Upstream commit d321ff589c16d8c2207485a6d7fbdb14e873d46e ] The TP_fast_assign() section is careful enough not to dereference xdr->rqst if it's NULL. The TP_STRUCT__entry section is not.

SUNRPC: Refresh the show_rqstp_flags() macro

2020-07-26T20:08:59Z

Ensure that show_rqstp_flags() can recognize and display the RQ_AUTHERR flag, added in commit 83dd59a0b9af ("SUNRPC/nfs: Fix return value for nfs4_callback_compound()") and the RQ_DATA flag, added in commit ff3ac5c3dc23 ("SUNRPC: Add a server side per-connection limit"). Signed-off-by: Chuck Lever

SUNRPC: trace RPC client lifetime events

2020-06-11T17:33:48Z

The "create" tracepoint records parts of the rpc_create arguments, and the shutdown tracepoint records when the rpc_clnt is about to signal pending tasks and destroy auths. Signed-off-by: Chuck Lever Signed-off-by: Anna Schumaker

SUNRPC: Trace transport lifetime events

2020-06-11T17:33:48Z

Refactor: Hoist create/destroy/disconnect tracepoints out of xprtrdma and into the generic RPC client. Some benefits include: - Enable tracing of xprt lifetime events for the socket transport types - Expose the different types of disconnect to help run down issues with lingering connections Signed-off-by: Chuck Lever Signed-off-by: Anna Schumaker

SUNRPC: Split the xdr_buf event class

2020-06-11T17:33:48Z
