v1: https://lore.kernel.org/linux-nfs/cover.1706124811.git.josef@xxxxxxxxxxxxxx/ v1->v2: - rework the sunprc service creation to take a pointer to the sv_stats. - dropped ->pg_stats from the svc_program. - converted all of the nfsd global stats to per-network namespace. - added the ability to point at a specific rpc_stat for rpc program creation. - converted the rpc stats for nfs to per-network namespace. -- Original email -- Hello, We're currently deploying NFS internally and have run into some oddities with our usage of containers. All of the services that mount and export NFS volumes run inside of containers, specifically all the namespaces including network namespaces. Our monitoring is done on a per-container basis, so we need access to the nfs and nfsd stats that are under /proc/net/sunrpc. However these are only tied to the init_net, which makes them invisible to containers in a different network namespace. Fix this so that these files are tied to the network namespace. This allows us to avoid the hack of bind mounting the hosts /proc into the container in order to do proper monitoring. Thanks, Josef Josef Bacik (13): sunrpc: don't change ->sv_stats if it doesn't exist nfs: stop setting ->pg_stats for unused stats sunrpc: pass in the sv_stats struct through svc_create* sunrpc: remove ->pg_stats from svc_program sunrpc: add a struct rpc_stats arg to rpc_create_args sunrpc: use the struct net as the svc proc private nfsd: rename NFSD_NET_* to NFSD_STATS_* nfsd: expose /proc/net/sunrpc/nfsd in net namespaces nfsd: make all of the nfsd stats per-network namespace nfsd: move th_cnt into nfsd_net nfsd: make svc_stat per-network namespace instead of global nfs: expose /proc/net/sunrpc/nfs in net namespaces nfs: make the rpc_stat per net namespace fs/lockd/svc.c | 5 +-- fs/nfs/callback.c | 5 +-- fs/nfs/client.c | 5 ++- fs/nfs/inode.c | 8 ++--- fs/nfs/internal.h | 2 -- fs/nfs/netns.h | 2 ++ fs/nfsd/cache.h | 2 -- fs/nfsd/netns.h | 28 ++++++++++++--- fs/nfsd/nfs4proc.c | 6 ++-- fs/nfsd/nfs4state.c | 3 +- fs/nfsd/nfscache.c | 40 +++++---------------- fs/nfsd/nfsctl.c | 16 ++++----- fs/nfsd/nfsfh.c | 3 +- fs/nfsd/nfssvc.c | 13 +++---- fs/nfsd/stats.c | 53 ++++++++++++---------------- fs/nfsd/stats.h | 70 +++++++++++++------------------------ fs/nfsd/vfs.c | 5 +-- include/linux/sunrpc/clnt.h | 1 + include/linux/sunrpc/svc.h | 9 +++-- net/sunrpc/clnt.c | 2 +- net/sunrpc/stats.c | 2 +- net/sunrpc/svc.c | 44 ++++++++++++++--------- 22 files changed, 147 insertions(+), 177 deletions(-) -- 2.43.0
