| * NFS: Implement SEEKAnna Schumaker2014-09-303-0/+23
| | | | | | | | | | | | | | | | | | The SEEK operation is used when an application makes an lseek call with either the SEEK_HOLE or SEEK_DATA flags set.

| | * lockd: move lockd's grace period handling into its own moduleJeff Layton2014-09-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, all of the grace period handling is part of lockd. Eventually though we'd like to be able to build v4-only servers, at which point we'll need to put all of this elsewhere. Move the code itself into fs/nfs_common and have it build a grace.ko module. Then, rejigger the Kconfig options so that both nfsd and lockd enable it automatically. Signed-off-by: Jeff Layton <jlayton@primarydata.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent NFS v4.2 drafts have removed NFS4ERR_METADATA_NOTSUPP and reassigned the error code to NFS4ERR_UNION_NOTSUPP. I also add in the NFS4ERR_OFFLOAD_NO_REQS error code. We're not using any of these yet, so there's no harm done. Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com> Signed-off-by: J.

| | * nfsd: allow turning off nfsv3 readdir_plusRajesh Ghanekar2014-08-181-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of our customer's application only needs file names, not file attributes. With directories having 10K+ inodes (assuming buffer cache has directory blocks cached having file names, but inode cache is limited and hence need eviction of older cached inodes), older inodes are evicted periodically. So if they keep on doing readdir(2) from NSF client on multiple directories, some directory's files are periodically removed from inode cache and hence new readdir(2) on same directory requires disk access to bring back inodes again to inode cache. As READDIRPLUS request fetches attributes also, doing getattr on each file on server, it causes unnecessary disk accesses. If READDIRPLUS on NFS client is returned with -ENOTSUPP, NFS client uses READDIR request which just gets the names of the files in a directory, not attributes, hence avoiding disk accesses on server. There's already a corresponding client-side mount option, but an export option reduces the need for configuration across multiple clients. This flag affects NFSv3 only. If it turns out it's needed for NFSv4 as well then we may have to figure out how to extend the behavior to NFSv4, but it's not currently obvious how to do that.

This isn't true - I was just over-engineering. Including a 'private' field in wait_bit_key instead of a focused "timeout" field was just premature generalization. If some other use is ever found, it can be generalized or added later. So this patch renames "private" to "timeout" with a meaning "stop waiting when "jiffies" reaches or passes "timeout", and adds two of the many possible wait..bit..timeout() interfaces: wait_on_page_bit_killable_timeout(), which is the one I want to use, and out_of_line_wait_on_bit_timeout() which is a reasonably general example. Others can be added as needed.

* | | NFSv4: use exponential retry on NFS4ERR_DELAY for async requests.NeilBrown2014-09-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently asynchronous NFSv4 request will be retried with exponential timeout (from 1/10 to 15 seconds), but async requests will always use a 15second retry. Some "async" requests are really synchronous though. The async mechanism is used to allow the request to continue if the requesting process is killed. In those cases, an exponential retry is appropriate. For example, if two different clients both open a file and get a READ delegation, and one client then unlinks the file (while still holding an open file descriptor), that unlink will used the "silly-rename" handling which is async. The first rename will result in NFS4ERR_DELAY while the delegation is reclaimed from the other client. The rename will not be retried for 15 seconds, causing an unlink to take 15 seconds rather than 100msec. This patch only added exponential timeout for async unlink and async rename. Other async calls, such as 'close' are sometimes waited for so they might benefit from exponential timeout too.

* | | SUNRPC: Don't wake tasks during connection abortBenjamin Coddington2014-09-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When aborting a connection to preserve source ports, don't wake the task in xs_error_report. This allows tasks with RPC_TASK_SOFTCONN to succeed if the connection needs to be re-established since it preserves the task's status instead of setting it to the status of the aborting kernel_connect(). This may also avoid a potential conflict on the socket's lock.

Solve this by: - Also rename all the stub functions __gpiod_* - Moving the vararg hack outside of #ifdef CONFIG_GPIOLIB so these will always be available.

It's broken as it changes led_blink_set() in a way that it can now sleep (while synchronously waiting for workqueue to be cancelled). That's a problem, because it's possible that this function gets called from atomic context (tpt_trig_timer() takes a readlock and thus disables preemption). This has been brought up 3 weeks ago already [1] but no proper fix has materialized, and I keep seeing the problem since 3.17-rc1.

Commit c66d039197e4 in v3.13 changed the behaviour to use 1-bit Hamming code via Hardware using a different ECC layout i.e. (ROM code layout) than what is used by software ECC. This ECC layout change causes NAND filesystems created in v3.12 and prior to be unusable in v3.13 and later. So revert back to using software ECC by default if an ECC scheme is not explicitely specified.

The foremost is that the function to calculate descriptor tag size returns sizes that are too big. This causes alignment issues on some architectures and is compounded by the fact that some parts of jbd2 use the structure size (incorrectly) to determine the presence of a 64bit journal instead of checking the feature flags. Therefore, introduce journal checksum v3, which enlarges the descriptor block tag format to allow for full 32-bit checksums of journal blocks, fix the journal tag function to return the correct sizes, and fix the jbd2 recovery code to use feature flags to determine 64bitness. Add a few function helpers so we don't have to open-code quite so many pieces. Switching to a 16-byte block size was found to increase journal size overhead by a maximum of 0.1%, to convert a 32-bit journal with no checksumming to a 32-bit journal with checksum v3 enabled.
