sunrpc: refactor pool_mode setting code

2024-07-08T18:10:05Z

Allow the pool_mode setting code to be called from internal callers so we can call it from a new netlink op. Add a new svc_pool_map_get function to return the current setting. Change the existing module parameter handling to use the new interfaces under the hood. Signed-off-by: Jeff Layton Signed-off-by: Chuck Lever

sunrpc: fix up the special handling of sv_nrpools == 1

2024-07-08T18:10:04Z

Only pooled services take a reference to the svc_pool_map. The sunrpc code has always used the sv_nrpools value to detect whether the service is pooled. The problem there is that nfsd is a pooled service, but when it's running in "global" pool_mode, it doesn't take a reference to the pool map because it has a sv_nrpools value of 1. This means that we have two separate codepaths for starting the server, depending on whether it's pooled or not. Fix this by adding a new flag to the svc_serv, that indicates whether the serv is pooled. With this we can have the nfsd service unconditionally take a reference, regardless of pool_mode. Note that this is a behavior change for /sys/module/sunrpc/parameters/pool_mode. Usually this file does not allow you to change the pool-mode while there are nfsd threads running, but if the pool-mode is "global" it's allowed. My assumption is that this is a bug, since it probably should never have worked this way. This patch changes the behavior such that you get back EBUSY even when nfsd is running in global mode. I think this is more reasonable behavior, and given that most people set this today using the module parameter, it's doubtful anyone will notice.

rpcrdma: Implement generic device removal

2024-07-08T17:47:24Z

Commit e87a911fed07 ("nvme-rdma: use ib_client API to detect device removal") explains the benefits of handling device removal outside of the CM event handler. Sketch in an IB device removal notification mechanism that can be used by both the client and server side RPC-over-RDMA transport implementations.

Revert "svcrdma: Add Write chunk WRs to the RPC's Send WR chain"

2024-04-20T15:20:41Z

Performance regression reported with NFS/RDMA using Omnipath, bisected to commit e084ee673c77 ("svcrdma: Add Write chunk WRs to the RPC's Send WR chain"). Tracing on the server reports: nfsd-7771 [060] 1758.891809: svcrdma_sq_post_err: cq.id=205 cid=226 sc_sq_avail=13643/851 status=-12 sq_post_err reports ENOMEM, and the rdma->sc_sq_avail (13643) is larger than rdma->sc_sq_depth (851). The number of available Send Queue entries is always supposed to be smaller than the Send Queue depth. That seems like a Send Queue accounting bug in svcrdma. As it's getting to be late in the 6.9-rc cycle, revert this commit. It can be revisited in a subsequent kernel release.
