* NSM: Remove include/linux/lockd/sm_inter.hChuck Lever2009-01-06

* NLM: Remove "create" argument from nsm_find()Chuck Lever2009-01-06
| | | | | | | | | | | | Clean up: nsm_find() now has only one caller, and that caller unconditionally sets the @create argument. Thus the @create argument is no longer needed. Since nsm_find() now has a more specific purpose, pick a more appropriate name for it. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
* NLM: Call nsm_reboot_lookup() instead of nsm_find()Chuck Lever2009-01-06
| | | | | | | | | | | | | Invoke the newly introduced nsm_reboot_lookup() function in nlm_host_rebooted() instead of nsm_find(). This introduces just one behavioral change: debugging messages produced during reboot notification will now appear when the NLMDBG_MONITOR flag is set, but not when the NLMDBG_HOSTCACHE flag is set.

* NLM: Decode "priv" argument of NLMPROC_SM_NOTIFY as an opaqueChuck Lever2009-01-06
| | | | | | | | | | | | | | | | | | | | | The NLM XDR decoders for the NLMPROC_SM_NOTIFY procedure should treat their "priv" argument truly as an opaque, as defined by the protocol, and let the upper layers figure out what is in it. This will make it easier to modify the contents and interpretation of the "priv" argument, and keep knowledge about what's in "priv" local to fs/lockd/mon.c. For now, the NLM and NSM implementations should behave exactly as they did before. The formation of the address of the rebooted host in nlm_host_rebooted() may look a little strange, but it is the inverse of how nsm_init_private() forms the private cookie. Plus, it's going away soon anyway. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
* NLM: Change nlm_host_rebooted() to take a single nlm_reboot argumentChuck Lever2009-01-06
| | | | | | | | | | | | | | Pass the nlm_reboot data structure directly from the NLMPROC_SM_NOTIFY XDR decoders to nlm_host_rebooted(). This eliminates some packing and unpacking of the NLMPROC_SM_NOTIFY results, and prepares for passing these results, including the "priv" cookie, directly to a lookup routine in fs/lockd/mon.c. This patch changes code organization but should not cause any behavioral change. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
* NSM: Move nsm_find() to fs/lockd/mon.cChuck Lever2009-01-06
| | | | | | | | | | | | | | | | | | | | | | The nsm_find() function sets up fresh nsm_handle entries. This is where we will store the "priv" cookie used to lookup nsm_handles during reboot recovery. The cookie will be constructed when nsm_find() creates a new nsm_handle. As much as possible, I would like to keep everything that handles a "priv" cookie in fs/lockd/mon.c so that all the smarts are in one source file. That organization should make it pretty simple to see how all this works. To me, it makes more sense than the current arrangement to keep nsm_find() with nsm_monitor() and nsm_unmonitor(). So, start reorganizing by moving nsm_find() into fs/lockd/mon.c. The nsm_release() function comes along too, since it shares the nsm_lock global variable.

* NSM: Release nsmhandle in nlm_destroy_hostChuck Lever2009-01-06
| | | | | | | | | | | | | | | | | | | | | | | The nsm_handle's reference count is bumped in nlm_lookup_host(). It should be decremented in nlm_destroy_host() to make it easier to see the balance of these two operations. Move the nsm_release() call to fs/lockd/host.c. The h_nsmhandle pointer is set in nlm_lookup_host(), and never cleared. The nlm_destroy_host() function is never called for the same nlm_host twice, so h_nsmhandle won't ever be NULL when nsm_unmonitor() is called. All references to the nlm_host are gone before it is freed. We can skip making h_nsmhandle NULL just before the nlm_host is deallocated. It's also likely we can remove the h_nsmhandle NULL check in nlmsvc_is_client() as well, but we can do that later when rearchitect- ing the nlm_host cache.

* NLM: Support IPv6 scope IDs in nlm_display_address()Chuck Lever2009-01-06
| | | | | | | | | | | | | Scope ID support is needed since the kernel's NSM implementation is about to use these displayed addresses as a mon_name in some cases. When nsm_use_hostnames is zero, without scope ID support NSM will fail to handle peers that contact us via a link-local address. Link-local addresses do not work without an interface ID, which is stored in the sockaddr's sin6_scope_id field. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.

* NLM: Remove address eye-catcher buffers from nlm_hostChuck Lever2009-01-06
| | | | | | | | | | | | | | | | The h_name field in struct nlm_host is a just copy of h_nsmhandle->sm_name. Likewise, the contents of the h_addrbuf field should be identical to the sm_addrbuf field. The h_srcaddrbuf field is used only in one place for debugging. We can live without this until we get %pI formatting for printk(). Currently these buffers are 48 bytes, but we need to support scope IDs in IPv6 presentation addresses, which means making the buffers even larger. Instead, let's find ways to eliminate them to save space. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

| * NLM: client-side nlm_lookup_host() should avoid matching on srcaddrChuck Lever2008-11-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit c98451bd, the loop in nlm_lookup_host() unconditionally compares the host's h_srcaddr field to the incoming source address. For client-side nlm_host entries, both are always AF_UNSPEC, so this check is unnecessary. Since commit 781b61a6, which added support for AF_INET6 addresses to nlm_cmp_addr(), nlm_cmp_addr() now returns FALSE for AF_UNSPEC addresses, which causes nlm_lookup_host() to create a fresh nlm_host entry every time it is called on the client. These extra entries will eventually expire once the server is unmounted, so the impact of this regression, introduced with lockd IPv6 support in 2.6.28, should be minor. We could fix this by adding an arm in nlm_cmp_addr() for AF_UNSPEC addresses, but really, nlm_lookup_host() shouldn't be matching on the srcaddr field for client-side nlm_host lookups.

* | knfsd: Remove NLM_HOST_MAX and associated logic.NeilBrown2008-04-23
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | Lockd caches information about hosts that have recently held locks to expedite the taking of further locks. It periodically discards this information for hosts that have not been used for a few minutes. lockd currently has a value NLM_HOST_MAX, and changes the 'garbage collection' behaviour when the number of hosts exceeds this threshold. However its behaviour is strange, and likely not what was intended. When the number of hosts exceeds the max, it scans *less* often (every 2 minutes vs every minute) and allows unused host information to remain around longer (5 minutes instead of 2). Having this limit is of dubious value anyway, and we have not suffered from the code not getting the limit right, so remove the limit altogether. We go with the larger values (discard 5 minute old hosts every 2 minutes) as they are probably safer. Maybe the periodic garbage collection should be replace to with 'shrinker' handler so we just respond to memory pressure....

* NLM: have server-side RPC clients default to soft RPC tasksJeff Layton2008-02-10
| | | | | | | | | | | | | | Now that it no longer does an RPC ping, lockd always ends up queueing an RPC task for the GRANT_MSG callback. But, it also requeues the block for later attempts.

* NLM: set RPC_CLNT_CREATE_NOPING for NLM RPC clientsJeff Layton2008-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | It's currently possible for an unresponsive NLM client to completely lock up a server's lockd. The scenario is something like this: 1) client1 (or a process on the server) takes a lock on a file 2) client2 tries to take a blocking lock on the same file and awaits the callback 3) client2 goes unresponsive (plug pulled, network partition, etc) 4) client1 releases the lock ...at that point the server's lockd will try to queue up a GRANT_MSG callback for client2, but first it requeues the block with a timeout of 30s. nlm_async_call will attempt to bind the RPC client to client2 and will call rpc_ping. rpc_ping entails a sync RPC call and if client2 is unresponsive it will take around 60s for that to time out. Once it times out, it's already time to retry the block and the whole process repeats. Once in this situation, nlmsvc_retry_blocked will never return until the host starts responding again. lockd won't service new calls. Fix this by skipping the RPC ping on NLM RPC clients. This makes nlm_async_call return quickly when called. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm.
