2021-03-22NFSD: Reduce svc_rqst::rq_pages churn during READDIR operationsChuck Lever1-0/+6
During NFSv2 and NFSv3 READDIR/PLUS operations, NFSD advances rq_next_page to the full size of the client-requested buffer, then releases all those pages at the end of the request. The next request to use that nfsd thread has to refill the pages. NFSD does this even when the dirlist in the reply is small. With NFSv3 clients that send READDIR operations with large buffer sizes, that can be 256 put_page/alloc_page pairs per READDIR request, even though those pages often remain unused. We can save some work by not releasing dirlist buffer pages that were not used to form the READDIR Reply. I've left the NFSv2 code alone since there are never more than three pages involved in an NFSv2 READDIR Reply. Eventually we should nail down why these pages need to be released at all in order to avoid allocating and releasing pages unnecessarily. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

2021-03-22NFSD: Update NFSv3 READDIR entry encoders to use struct xdr_streamChuck Lever3-30/+185
The benefit of the xdr_stream helpers is that they transparently handle encoding an XDR data item that crosses page boundaries. Most of the open-coded logic to do that here can be eliminated. A sub-buffer and sub-stream are set up as a sink buffer for the directory entry encoder. As an entry is encoded, it is added to the end of the content in this buffer/stream. The total length of the directory list is tracked in the buffer's @len field. When it comes time to encode the Reply, the sub-buffer is merged into rq_res's page array at the correct place using xdr_write_pages(). Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

2021-03-22NFSD: Extract the svcxdr_init_encode() helperChuck Lever5-84/+69
NFSD initializes an encode xdr_stream only after the RPC layer has already inserted the RPC Reply header. Thus it behaves differently than xdr_init_encode does, which assumes the passed-in xdr_buf is entirely devoid of content. nfs4proc.c has this server-side stream initialization helper, but it is visible only to the NFSv4 code. Move this helper to a place that can be accessed by NFSv2 and NFSv3 server XDR functions. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

2021-03-21io_uring: call req_set_fail_links() on short send[msg]()/recv[msg]() with ↵Stefan Metzmacher1-4/+20
MSG_WAITALL Without that it's not safe to use them in a linked combination with others. Now combinations like IORING_OP_SENDMSG followed by IORING_OP_SPLICE should be possible. We already handle short reads and writes for the following opcodes: - IORING_OP_READV - IORING_OP_READ_FIXED - IORING_OP_READ - IORING_OP_WRITEV - IORING_OP_WRITE_FIXED - IORING_OP_WRITE - IORING_OP_SPLICE - IORING_OP_TEE Now we have it for these as well: - IORING_OP_SENDMSG - IORING_OP_SEND - IORING_OP_RECVMSG - IORING_OP_RECV For IORING_OP_RECVMSG we also check for the MSG_TRUNC and MSG_CTRUNC flags in order to call req_set_fail_links(). There might be applications arround depending on the behavior that even short send[msg]()/recv[msg]() retuns continue an IOSQE_IO_LINK chain. It's very unlikely that such applications pass in MSG_WAITALL, which is only defined in 'man 2 recvmsg', but not in 'man 2 sendmsg'. It's expected that the low level sock_sendmsg() call just ignores MSG_WAITALL, as MSG_ZEROCOPY is also ignored without explicitly set SO_ZEROCOPY. We also expect the caller to know about the implicit truncation to MAX_RW_COUNT, which we don't detect. cc: netdev@vger.kernel.org Link: https://lore.kernel.org/r/c4e1a4cc0d905314f4d5dc567e65a7b09621aab3.1615908477.git.metze@samba.org Signed-off-by: Stefan Metzmacher <metze@samba.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>

2021-03-21ext4: fix rename whiteout with fast commitHarshad Shirwadkar3-2/+12
This patch adds rename whiteout support in fast commits. Note that the whiteout object that gets created is actually char device. Which imples, the function ext4_inode_journal_mode(struct inode *inode) would return "JOURNAL_DATA" for this inode. This has a consequence in fast commit code that it will make creation of the whiteout object a fast-commit ineligible behavior and thus will fall back to full commits. With this patch, this can be observed by running fast commits with rename whiteout and seeing the stats generated by ext4_fc_stats tracepoint as follows: ext4_fc_stats: dev 254:32 fc ineligible reasons: XATTR:0, CROSS_RENAME:0, JOURNAL_FLAG_CHANGE:0, NO_MEM:0, SWAP_BOOT:0, RESIZE:0, RENAME_DIR:0, FALLOC_RANGE:0, INODE_JOURNAL_DATA:16; num_commits:6, ineligible: 6, numblks: 3 So in short, this patch guarantees that in case of rename whiteout, we fall back to full commits. Amir mentioned that instead of creating a new whiteout object for every rename, we can create a static whiteout object with irrelevant nlink. That will make fast commits to not fall back to full commit. But until this happens, this patch will ensure correctness by falling back to full commits.

However s_error_work may report another fs error and re-arm timer thus resulting in timer use-after-free.

2021-03-19cifs: fix allocation size on newly created filesSteve French1-1/+9
Applications that create and extend and write to a file do not expect to see 0 allocation size. When file is extended, set its allocation size to a plausible value until we have a chance to query the server for it. When the file is cached this will prevent showing an impossible number of allocated blocks (like 0). This fixes e.g. xfstests 614 which does 1) create a file and set its size to 64K 2) mmap write 64K to the file 3) stat -c %b for the file (to query the number of allocated blocks) It was failing because we returned 0 blocks. Even though we would return the correct cached file size, we returned an impossible allocation size.

2021-03-18io_uring: don't leak creds on SQO attach errorPavel Begunkov1-11/+6
Attaching to already dead/dying SQPOLL task is disallowed in io_sq_offload_create(), but cleanup is hand coded by calling io_put_sq_data()/etc., that miss to put ctx->sq_creds. Defer everything to error-path io_sq_thread_finish(), adding ctx->sqd_list in the error case as well as finish will handle it.
