Hi Anna- Here's the complete series of my patches that are ready for the v5.1 merge window. All of them have been previously posted for review. There are four main sets: - the first three are RPC-over-RDMA-related fixes - the next seven are observability improvements - the next eight overhaul the RPC auth layer to use xdr_stream - the last five reduce the size of RPC receive buffers --- Chuck Lever (23): xprtrdma: Fix sparse warnings xprtrdma: Check inline size before providing a Write chunk xprtrdma: Reduce the doorbell rate (Receive) SUNRPC: Display symbolic flag names in RPC trace events SUNRPC: Add xdr_stream::rqst field SUNRPC: Add XDR overflow trace event SUNRPC: Add trace event that reports reply page vector alignment NFS: Remove print_overflow_msg() NFS: Add trace events to report non-zero NFS status codes SUNRPC: Remove some dprintk() call sites from auth functions SUNRPC: Remove rpc_xprt::tsh_size SUNRPC: Add build option to disable support for insecure enctypes SUNRPC: Use struct xdr_stream when constructing RPC Call header SUNRPC: Clean up rpc_verify_header() SUNRPC: Use struct xdr_stream when decoding RPC Reply header SUNRPC: Introduce trace points in rpc_auth_gss.ko SUNRPC: Remove xdr_buf_trim() SUNRPC: Add SPDX IDs to some net/sunrpc/auth_gss/ files SUNRPC: Introduce rpc_prepare_reply_pages() NFS: Account for XDR pad of buf->pages SUNRPC: Make AUTH_SYS and AUTH_NULL set au_verfsize SUNRPC: Add rpc_auth::au_ralign field SUNRPC: Use au_rslack when computing reply buffer size fs/lockd/clnt4xdr.c | 14 - fs/lockd/clntxdr.c | 14 - fs/nfs/callback_xdr.c | 64 +-- fs/nfs/flexfilelayout/flexfilelayout.c | 2 fs/nfs/nfs2xdr.c | 124 ++---- fs/nfs/nfs3xdr.c | 209 +++-------- fs/nfs/nfs42xdr.c | 21 - fs/nfs/nfs4trace.h | 25 + fs/nfs/nfs4xdr.c | 529 ++++++++------------------- fs/nfs/nfstrace.c | 1 fs/nfs/nfstrace.h | 85 ++++ fs/nfsd/nfs4callback.c | 13 - include/linux/sunrpc/auth.h | 44 +- include/linux/sunrpc/clnt.h | 3 include/linux/sunrpc/gss_krb5_enctypes.h | 42 ++ include/linux/sunrpc/xdr.h | 23 + include/linux/sunrpc/xprt.h | 7 include/trace/events/rpcgss.h | 361 ++++++++++++++++++ include/trace/events/rpcrdma.h | 12 + include/trace/events/sunrpc.h | 361 ++++++++++++++++++ net/sunrpc/Kconfig | 16 + net/sunrpc/auth.c | 136 ++++--- net/sunrpc/auth_gss/Makefile | 2 net/sunrpc/auth_gss/auth_gss.c | 551 ++++++++++++++-------------- net/sunrpc/auth_gss/gss_krb5_mech.c | 29 - net/sunrpc/auth_gss/gss_krb5_wrap.c | 8 net/sunrpc/auth_gss/gss_mech_switch.c | 27 - net/sunrpc/auth_gss/gss_rpc_upcall.c | 15 - net/sunrpc/auth_gss/gss_rpc_upcall.h | 16 - net/sunrpc/auth_gss/gss_rpc_xdr.c | 15 - net/sunrpc/auth_gss/gss_rpc_xdr.h | 17 - net/sunrpc/auth_gss/svcauth_gss.c | 3 net/sunrpc/auth_gss/trace.c | 11 + net/sunrpc/auth_null.c | 56 ++- net/sunrpc/auth_unix.c | 120 ++++-- net/sunrpc/clnt.c | 390 ++++++++++---------- net/sunrpc/svc.c | 19 - net/sunrpc/xdr.c | 121 +++--- net/sunrpc/xprt.c | 10 - net/sunrpc/xprtrdma/backchannel.c | 2 net/sunrpc/xprtrdma/frwr_ops.c | 4 net/sunrpc/xprtrdma/rpc_rdma.c | 22 + net/sunrpc/xprtrdma/svc_rdma_backchannel.c | 1 net/sunrpc/xprtrdma/transport.c | 1 net/sunrpc/xprtrdma/verbs.c | 2 net/sunrpc/xprtrdma/xprt_rdma.h | 12 + net/sunrpc/xprtsock.c | 91 +++-- 47 files changed, 2071 insertions(+), 1580 deletions(-) create mode 100644 include/trace/events/rpcgss.h create mode 100644 net/sunrpc/auth_gss/trace.c -- Chuck Lever
