NFSv4.2: Rework scratch handling for READ_PLUS

2023-09-13T07:42:48+00:00

[ Upstream commit fbd2a05f29a95d5b42b294bf47e55a711424965b ] Instead of using a tiny, static scratch buffer, we should use a kmalloc()-ed buffer that is allocated when checking for read plus usage. This lets us use the buffer before decoding any part of the READ_PLUS operation instead of setting it right before segment decoding, meaning it should be a little more robust.

nfs: only issue commit in DIO codepath if we have uncommitted data

2022-07-23T19:28:59+00:00

Currently, we try to determine whether to issue a commit based on nfs_write_need_commit which looks at the current verifier. In the case where we got a short write and then tried to follow it up with one that failed, the verifier can't be trusted. What we really want to know is whether the pgio request had any successful writes that came back as UNSTABLE. Add a new flag to the pgio request, and use that to indicate that we've had a successful unstable write. Only issue a commit if that flag is set.

NFSv4: Fix free of uninitialized nfs4_label on referral lookup.

2022-05-31T21:09:24+00:00

Send along the already-allocated fattr along with nfs4_fs_locations, and drop the memcpy of fattr. We end up growing two more allocations, but this fixes up a crash as: PID: 790 TASK: ffff88811b43c000 CPU: 0 COMMAND: "ls" #0 [ffffc90000857920] panic at ffffffff81b9bfde #1 [ffffc900008579c0] do_trap at ffffffff81023a9b #2 [ffffc90000857a10] do_error_trap at ffffffff81023b78 #3 [ffffc90000857a58] exc_stack_segment at ffffffff81be1f45 #4 [ffffc90000857a80] asm_exc_stack_segment at ffffffff81c009de #5 [ffffc90000857b08] nfs_lookup at ffffffffa0302322 [nfs] #6 [ffffc90000857b70] __lookup_slow at ffffffff813a4a5f #7 [ffffc90000857c60] walk_component at ffffffff813a86c4 #8 [ffffc90000857cb8] path_lookupat at ffffffff813a9553 #9 [ffffc90000857cf0] filename_lookup at ffffffff813ab86b Suggested-by: Trond Myklebust Fixes: 9558a007dbc3 ("NFS: Remove the label from the nfs4_lookup_res struct") Signed-off-by: Benjamin Coddington Signed-off-by: Anna Schumaker

NFSv4: Add encoders/decoders for the NFSv4.1 dacl and sacl attributes

NFSv4: keep state manager thread active if swap is enabled

2022-03-13T16:59:35+00:00

If we are swapping over NFSv4, we may not be able to allocate memory to start the state-manager thread at the time when we need it. So keep it always running when swap is enabled, and just signal it to start. This requires updating and testing the cl_swapper count on the root rpc_clnt after following all ->cl_parent links.
