The following patch adds support for the PixelView Ultra Pro video capture card in v4l. - It removes the remote control key definitions from ir-kbd-gpio.c and moves them to ir-common.c so that they can be shared between bt878 and cx88 based cards. - The patch also moves the FUSIONHDTV_3_GOLD_Q card from number 27 to 28 to regain compatibility with the V4L cvs. Signed-off-by:

This patch allows full analog functionality for the DViCO FusionHDTV3 Gold-Q, 18ac:d820 which has a Conexant cx23882, Thompson7611, and LG 3202. It does NOT yet support digital decoding or digital audio without the internal analog audio jack connected to the sound board, but it works perfectly in analog mode. Signed-off-by:

This patch adds the code to create and remove client subdirectories from the recovery directory, as described in the previous patch comment. Signed-off-by:

NFSv4 clients are required to know what state they have on the server so that they can reclaim it on server reboot. However, it is possible for pathalogical combinations of server reboots and network partitions to leave a client in a state where it cannot know whether it has lost its state on the server. For this reason, rfc3530 requires that we store some information about clients to stable storage. So we maintain a directory /var/lib/nfs/v4recovery with a subdirectory for each client with active state. We leave open the possibility of including files underneath each such subdirectory with information about the client, but for now the subdirectories are empty. We create a client subdirectory whenever a client makes its first non-reclaim open_confirm. We remove a client subdirectory whenever either a) its lease expires, or b) the grace period ends without it reclaiming anything. When handling reclaims, we allow the reclaim if and only if the client doing the reclaim has a subdirectory. This patch adds just the code to scan the recovery directory on nfsd startup.

The cb_parsed field is only used by probe_callback, to determine whether the callback information has been filled in by setclientid. But there is no way that probe_callback() can be called without that having already happened, so that check is superfluous, as is cb_parsed. Signed-off-by:

>From the language of rfc3530 section 8.1.3 (e.g., the suggestion that a "process id" might be a reasonable lockowner value) it's conceivable that a client might want to use the same lockowner string on multiple files, so we may as well allow that. We expect each use of open_to_lockowner to create a distinct seqid stream, though. For now we're also allowing multiple uses of open_to_lockowner with the same open, though it seems unlikely clients would actually do that. Also add a comment reminding myself of some very non-scalable data structures. Signed-off-by:

Trivial renaming patch: I can never remember, while looking at various lists relating the nfsd4 state structures, which are the "heads" and which are items on other lists, or which structures are actually on the various lists. The following convention helps me: given structures foo and bar, with foo containing the head of a list of bars, use "bars" for the name of the head of the list contained in the struct foo, and use "per_foo" for the entries in the struct bars. Already done for struct nfs4_file; go ahead and do it for the other nfsd4 state structures. Signed-off-by:

Setclientid_confirm code confused states 1 and 3 (numbering from the IMPLEMENTATION section of rfc3530, section 14.2.33). Fix this. State 1 allows the client to change the callback channel on the fly. We don't implement this currently, so just turn off the callback channel in this case. From: Fred Isaman Signed-off-by:

For the purposes of reboot recovery, we want to do some work during the transition period at the end of the grace period. Some of that work must be guaranteed to have a certain relationship with the end of the grace period, so we want to control the transition there. Our approach is to modify the in_grace() checks to consult a global variable instead of checking the time directly, to schedule the first run of the laundromat thread at the end of the grace period, and to set the global end-of-grace-period there.

For the purposes of reboot recovery we keep a directory with subdirectories each having a name that is the ascii hex representation of the md5 sum of a client identifier for an active client. This adds the code to calculate that name. We also use it for the purposes of comparing clients, so if someone ever manages to find two client names that are md5 collisions, then we'll return clid_inuse to the second. Signed-off-by:

Allow recovery of delegations after reboot. Signed-off-by:
-
NeilBrown authored
The only way the protocol gives to change the lease time on the fly is to simulate a reboot. We don't have that completely right in the current code; among other things, we should probably put lockd in grace too while we do this. For now, let's just keep this simple, and wait till the next time nfsd starts to register any changes in lease time. If the administrator really wants to change the lease time *now*, they can go ahead and bring nfsd down and then back up again after changing the lease time. Also remove the "if (reclaim_str_hashtbl_size == 0)" case, a shortcut which skips the grace period if we know of no clients in need of recovery. This isn't going to work well with nlm. Signed-off-by:

We're running the laundromat work on the default kevent worker thread. But the laundromat takes the nfsv4 state semaphore, which is used for way too much stuff, and the potential for deadlocks is high. Better to have this on a separate workqueue. Signed-off-by:

rpc_create_client was modified recently to do its own (synchronous) NULL ping of the server. We'd rather do that on our own, asynchronously, so that we don't have to block the nfsd thread doing the probe, and so that setclientid handling (hence, client mounts) can proceed normally whether the callback is succesful or not. (We can still function fine without the callback channel--we just won't be able to give out delegations till it's verified to work.) Signed-off-by:

Add a struct kref to each nfs4_file and take a reference to it from each stateid and delegation that refers to it. The atomicity guarantees are overkill given that all this stuff is done under the single nfsd4 state lock, but a) we'd like finer-grained locking some day, and b) this simplifies the cleanup of the structures a bit, something that has previously been a bit complicated and bug-prone.
