If the server supports the NFSv4.2 protocol extension to optimise away returning a stateid when it returns a delegation, then we cache that information in another capability flag. Signed-off-by:

Query the server for the OPEN arguments that it supports so that we can figure out which extensions we can use. Signed-off-by:
-
Trond Myklebust authored
If the timestamps and size are delegated to the client, then it is authoritative w.r.t. their values, so we should not be requesting those values from the server. Note that this allows us to optimise away most GETATTR calls if the only changes to the attributes are the result of read() or write(). Signed-off-by:

nfs_setattr calls nfs_update_inode() directly, so we have to reset the m/ctime there. Signed-off-by:

Trond Myklebust authored
If the atime or mtime attributes were delegated, then we need to propagate their new values back to the server when returning the delegation. Signed-off-by:

If we see that the server supports attribute delegations, then request them by setting the appropriate OPEN arguments. Signed-off-by:

Cache whether or not the server may have support for delegated attributes in a capability flag. Signed-off-by:
-
Trond Myklebust authored
After a reboot of the NFSv4.2 server, the recovery code needs to specify whether the delegation to be recovered is an attribute delegation or not. Signed-off-by:

Trond Myklebust authored
Ensure that we update the mtime and atime correctly when we read or write data to the file and when we truncate. Let the server manage ctime on other attribute updates. Signed-off-by:

Trond Myklebust authored
This argument will be used to allow the caller to specify whether or not they need to know that this is an attribute delegation. Signed-off-by:

Trond Myklebust authored
When the client holds an attribute delegation, the server may retrieve all the timestamps through a CB_GETATTR callback. Signed-off-by:

Modify it to no longer depend directly on the struct opendata. This will enable sharing with WANT_DELEGATION. Signed-off-by:

Trond Myklebust authored
Instead of having the fields open coded in the struct nfs_openres, add a separate structure for them so that we can reuse that code for the WANT_DELEGATION case. Signed-off-by:

Prior to the commit identified below, call_transmit_status() would handle -EPERM and other errors related to an unreachable server by falling through to call_status() which added a 3-second delay and handled the failure as a timeout. Since that commit, call_transmit_status() falls through to handle_bind(). For UDP this moves straight on to handle_connect() and handle_transmit() so we immediately retransmit - and likely get the same error. This results in an indefinite loop in __rpc_execute() which triggers a soft-lockup warning. For the errors that indicate an unreachable server, call_transmit_status() should fall back to call_status() as it did before. This cannot cause the thundering herd that the previous patch was avoiding, as the call_status() will insert a delay.

The original code was designed so that most calls to rpcrdma_rep_create() would occur on the NUMA node that the device preferred. There are a few cases where that's not possible, so those reps are marked as temporary. However, we have the device (and its preferred node) already in rpcrdma_rep_create(), so let's use that to guarantee the memory is allocated from the correct node. Signed-off-by:

Avoid FastReg operations getting MW_BIND_ERR after a reconnect. rpcrdma_reqs_reset() is called on transport tear-down to get each rpcrdma_req back into a clean state. MRs on req->rl_registered are waiting for a FastReg, are already registered, or are waiting for invalidation. If the transport is being torn down when reqs_reset() is called, the matching LocalInv might never be posted. That leaves these MR registered /and/ on req->rl_free_mrs, where they can be re-used for the next connection. Since xprtrdma does not keep specific track of the MR state, it's not possible to know what state these MRs are in, so the only safe thing to do is release them immediately.

asm-generic/barrier.h and asm/bitops.h are already brought into the file through the header linux/sunrpc/svc_rdma.h and the file can still be built with their removal. They have been replaced with the preferred linux/bitops.h and asm/barrier.h to remove the need for the asm-generic header. Suggested-by:

Currently building the powerpc selftests with USERCFLAGS set to anything causes the build to break: $ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error ... gcc -Wno-error cache_shape.c ... cache_shape.c:18:10: fatal error: utils.h: No such file or directory 18 | #include "utils.h" | ^~~~~~~~~ compilation terminated. This happens because the USERCFLAGS are added to CFLAGS in lib.mk, which causes the check of CFLAGS in powerpc/flags.mk to skip setting CFLAGS at all, resulting in none of the usual CFLAGS being passed. That can be seen in the output above, the only flag passed to the compiler is -Wno-error. Fix it by dropping the conditional setting of CFLAGS in flags.mk. Instead always set CFLAGS, but also append USERCFLAGS if they are set. Note that appending to CFLAGS (with +=) wouldn't work, because flags.mk is included by multiple Makefiles (to support partial builds), causing CFLAGS to be appended to multiple times. Additionally that would place the USERCFLAGS prior to the standard CFLAGS, meaning the USERCFLAGS couldn't override the standard flags. Being able to override the standard flags is desirable, for example for adding -Wno-error. With the fix in place, the CFLAGS are set correctly, including the USERCFLAGS: $ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error ... gcc -std=gnu99 -O2 -Wall -Werror -DGIT_VERSION='"v6.10-rc2-7-gdea17e7e56c3"' -I/home/michael/linux/tools/testing/selftests/powerpc/include -Wno-error cache_shape.c ...
