| * NFS: Switch from intr mount option to TASK_KILLABLEMatthew Wilcox2007-12-061-5/+1
| | | | | | | | | | | | | | | | | | By using the TASK_KILLABLE infrastructure, we can get rid of the 'intr' mount option.

* | NFS: Adjust nfs_clone_mount structure to store "struct sockaddr *"Chuck Lever2008-01-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the addr field in the nfs_clone_mount structure to store a "struct sockaddr *" to support non-IPv4 addresses in the NFS client. Note this is mostly a cosmetic change, and does not actually allow referrals using IPv6 addresses. The existing referral code assumes that the server returns a string that represents an IPv4 address. This code needs to support hostnames and IPv6 addresses as well as IPv4 addresses, thus it will need to be reorganized completely (to handle DNS resolution in user space).

* | NFS: Clean up address comparison in __nfs_find_client()Chuck Lever2008-01-301-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The address comparison in the __nfs_find_client() function is deceptive. It uses a memcmp() to check a pair of u32 fields for equality. Not only is this inefficient, but usually memcmp() is used for comparing two *whole* sockaddr_in's (which includes comparisons of the address family and port number), so it's easy to mistake the comparison here for a whole sockaddr comparison, which it isn't. So for clarity and efficiency, we replace the memcmp() with a simple test for equality between the two s_addr fields. This should have no behavioral effect.

* Detach sched.h from mm.hAlexey Dobriyan2007-05-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

* | NFS: disconnect before retrying NFSv4 requests over TCPChuck Lever2007-02-131-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RFC3530 section 3.1.1 states an NFSv4 client MUST NOT send a request twice on the same connection unless it is the NULL procedure. Section 3.1.1 suggests that the client should disconnect and reconnect if it wants to retry a request. Implement this by adding an rpc_clnt flag that an ULP can use to specify that the underlying transport should be disconnected on a major timeout. The NFSv4 client asserts this new flag, and requests no retries after a minor retransmit timeout. Note that disconnecting on a retransmit is in general not safe to do if the RPC client does not reuse the TCP port number when reconnecting.

* WorkStruct: Pass the work_struct pointer instead of context dataDavid Howells2006-11-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass the work_struct pointer to the work function rather than context data. The work function can use container_of() to work out the data. For the cases where the container of the work_struct may go away the moment the pending bit is cleared, it is made possible to defer the release of the structure by deferring the clearing of the pending bit. To make this work, an extra flag is introduced into the management side of the work_struct. This governs auto-release of the structure upon execution. Ordinarily, the work queue executor would release the work_struct for further scheduling or deallocation by clearing the pending bit prior to jumping to the work function. This means that, unless the driver makes some guarantee itself that the work_struct won't go away, the work function may not access anything else in the work_struct or its container lest they be deallocated.. This is a problem if the auxiliary data is taken away (as done by the last patch). However, if the pending bit is *not* cleared before jumping to the work function, then the work function *may* access the work_struct and its container with no problems. But then the work function must itself release the work_struct by calling work_release(). In most cases, automatic release is fine, so this is the default. Special initiators exist for the non-auto-release case (ending in _NAR). Signed-Off-By: David Howells <dhowells@redhat.com>

| | | | | | | | | | | | Separate delayable work items from non-delayable work items be splitting them into a separate structure (delayed_work), which incorporates a work_struct and the timer_list removed from work_struct. The work_struct struct is huge, and this limits it's usefulness. On a 64-bit architecture it's nearly 100 bytes in size. This reduces that by half for the non-delayable type of event.

* [PATCH] knfsd: be more selective in which sockets lockd listens onNeilBrown2006-10-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently lockd listens on UDP always, and TCP if CONFIG_NFSD_TCP is set. However as lockd performs services of the client as well, this is a problem. If CONFIG_NfSD_TCP is not set, and a tcp mount is used, the server will not be able to call back to lockd. So: - add an option to lockd_up saying which protocol is needed - Always open sockets for which an explicit port was given, otherwise only open a socket of the type required - Change nfsd to do one lockd_up per socket rather than one per thread. This - removes the dependancy on CONFIG_NFSD_TCP - means that lockd may open sockets other than at startup - means that lockd will *not* listen on UDP if the only mounts are TCP mount (and nfsd hasn't started). The latter is the only one that concerns me at all - I don't know if this might be a problem with some servers.
