2019-02-21NFSv4.1: Avoid false retries when RPC calls are interruptedTrond Myklebust3-60/+55
A 'false retry' in NFSv4.1 occurs when the client attempts to transmit a new RPC call using a slot+sequence number combination that references an already cached one. Currently, the Linux NFS client will do this if a user process interrupts an RPC call that is in progress. The problem with doing so is that we defeat the main mechanism used by the server to differentiate between a new call and a replayed one. Even if the server is able to perfectly cache the arguments of the old call, it cannot know if the client intended to replay or send a new call. The obvious fix is to bump the sequence number pre-emptively if an RPC call is interrupted, but in order to deal with the corner cases where the interrupted call is not actually received and processed by the server, we need to interpret the error NFS4ERR_SEQ_MISORDERED as a sign that we need to either wait or locate a correct sequence number that lies between the value we sent, and the last value that was acked by a SEQUENCE call on that slot.

2019-02-21pNFS: Avoid read/modify/write when it is not necessaryKazuo Ito1-14/+26
As the block and SCSI layouts can only read/write fixed-length blocks, we must perform read-modify-write when data to be written is not aligned to a block boundary or smaller than the block size. (612aa983a0410 pnfs: add flag to force read-modify-write in ->write_begin) The current code tries to see if we have to do read-modify-write on block-oriented pNFS layouts by just checking !PageUptodate(page), but the same condition also applies for overwriting of any uncached potions of existing files, making such operations excessively slow even it is block-aligned. The change does not affect the optimization for modify-write-read cases (38c73044f5f4d NFS: read-modify-write page updating), because partial update of !PageUptodate() pages can only happen in layouts that can do arbitrary length read/write and never in block-based ones. Testing results: We ran fio on one of the pNFS clients running 4.20 kernel (vanilla and patched) in this configuration to read/write/overwrite files on the storage array, exported as pnfs share by the server. pNFS clients ---1G Ethernet--- pNFS server (HP DL360 G8) (HP DL360 G8) | | | | +------8G Fiber Channel--------+ | Storage Array (HP P6350) Throughput of overwrite (both buffered and O_SYNC) is noticeably improved.

2019-02-21NFS: readdirplus optimization by cache mechanismluanshi2-7/+86
When listing very large directories via NFS, clients may take a long time to complete. There are about three factors involved: First of all, ls and practically every other method of listing a directory including python os.listdir and find rely on libc readdir(). However readdir() only reads 32K of directory entries at a time, which means that if you have a lot of files in the same directory, it is going to take an insanely long time to read all the directory entries. Secondly, libc readdir() reads 32K of directory entries at a time, in kernel space 32K buffer split into 8 pages. One NFS readdirplus rpc will be called for one page, which introduces many readdirplus rpc calls. Lastly, one NFS readdirplus rpc asks for 32K data (filled by nfs_dentry) to fill one page (filled by dentry), we found that nearly one third of data was wasted. To solve above problems, pagecache mechanism was introduced. One NFS readdirplus rpc will ask for a large data (more than 32k), the data can fill more than one page, the cached pages can be used for next readdir call. This can reduce many readdirplus rpc calls and improve readdirplus performance. TESTING: When listing very large directories(include 300 thousand files) via NFS time ls -l /nfs_mount | wc -l without the patch: 300001 real 1m53.524s user 0m2.314s sys 0m2.599s with the patch: 300001 real 0m23.487s user 0m2.305s sys 0m2.558s Improved performance: 79.6% readdirplus rpc calls decrease: 85% Signed-off-by: Liguang Zhang <zhangliguang@linux.alibaba.com> Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>

2019-02-21SUNRPC: Use poll() to fix up the socket requeue racesTrond Myklebust1-2/+24
Because we clear XPRT_SOCK_DATA_READY before reading, we can end up with a situation where new data arrives, causing xs_data_ready() to queue up a second receive worker job for the same socket, which then immediately gets stuck waiting on the transport receive mutex. The fix is to only clear XPRT_SOCK_DATA_READY once we're done reading, and then to use poll() to check if we might need to queue up a new job in order to deal with any new data.

2019-02-19net: stmmac: Fix a race in EEE enable callbackJose Abreu1-10/+12

Fix this by only saving the EEE parameters after all operations are performed with success.
