Subject: [PATCH v8 0/3] add rpc_status netlink support for NFSD
Date: Mon, 11 Sep 2023 14:49:43 +0200 [thread overview]
Message-ID: <cover.1694436263.git.lorenzo@kernel.org> (raw)
Introduce rpc_status netlink support for NFSD in order to dump pending
RPC requests debugging information from userspace.
The new code can be tested with the user-space tool reported below:
https://github.com/LorenzoBianconi/nfsd-rpc-netlink-monitor/tree/main
Changes since v7:
- introduce nfsd_server.yaml for netlink messages
Changes since v6:
- report info to user-space through netlink and get rid of the related
entry in the procfs
Changes since v5:
- add missing delimiters for nfs4 compound ops
- add a header line for rpc_status handler
- do not dump rq_prog
- do not dump rq_flags in hex
Changes since v4:
- rely on acquire/release APIs and get rid of atomic operation
- fix kdoc for nfsd_rpc_status_open
- get rid of ',' as field delimiter in nfsd_rpc_status hanlder
- move nfsd_rpc_status before nfsd_v4 enum entries
- fix compilantion error if nfsdv4 is not enabled
Changes since v3:
- introduce rq_status_counter in order to detect if the RPC request is
pending and RPC info are stable
- rely on __svc_print_addr to dump IP info
Changes since v2:
- minor changes in nfsd_rpc_status_show output
Changes since v1:
- rework nfsd_rpc_status_show output
Changes since RFCv1:
- riduce time holding nfsd_mutex bumping svc_serv refcoung in
nfsd_rpc_status_open()
- dump rqstp->rq_stime
- add missing kdoc for nfsd_rpc_status_open()
