nfs: don't share pNFS DS connections between net namespaces

2025-04-28T03:25:44+00:00

Currently, different NFS clients can share the same DS connections, even when they are in different net namespaces. If a containerized client creates a DS connection, another container can find and use it. When the first client exits, the connection will close which can lead to stalls in other clients. Add a net namespace pointer to struct nfs4_pnfs_ds, and compare those value to the caller's netns in _data_server_lookup_locked() when searching for a nfs4_pnfs_ds to match.

nfs: pass struct nfsd_file to nfs_init_pgio and nfs_init_commit

2024-09-23T19:03:30+00:00

The nfsd_file will be passed, in future commits, by callers that enable LOCALIO support (for both regular NFS and pNFS IO).

nfs: remove dead code for the old swap over NFS implementation

2024-07-08T17:47:51+00:00

Remove the code testing folio_test_swapcache either explicitly or implicitly in pagemap.h headers, as is now handled using the direct I/O path and not the buffered I/O path that these helpers are located in. Signed-off-by: Christoph Hellwig Reviewed-by: Sagi Grimberg Signed-off-by: Anna Schumaker

pNFS: rework pnfs_generic_pg_check_layout to check IO range

2024-05-21T12:34:15+00:00

All callers of pnfs_generic_pg_check_layout() also want to do a call to check that the layout's range covers the IO range. Merge the functionality of the pnfs_generic_pg_check_range() into that of pnfs_generic_pg_check_layout().

pNFS/filelayout: Specify the layout segment range in LAYOUTGET

2024-05-20T15:06:18+00:00

Move from only requesting full file layout segments to requesting layout segments that match our I/O size. This means the server is still free to return a full file layout if it wants, but partial layouts will no longer cause an error. Signed-off-by: Anna Schumaker Signed-off-by: Trond Myklebust

pNFS/filelayout: Remove the whole file layout requirement

pnfs/filelayout: add tracepoint to getdeviceinfo

2024-02-28T21:18:19+00:00

While decoding filelayout getdeviceinfo received, print out the information about the location of data servers (IPs). Generic getdeviceinfo tracepoints prints the MDS's ip for the dstaddr. In this patch, separate the MDS's address from the DS's addresses. Signed-off-by: Olga Kornievskaia Signed-off-by: Trond Myklebust
