2022-01-27lockd: fix failure to cleanup client locksJ. Bruce Fields
In my testing, we're sometimes hitting the request->fl_flags & FL_EXISTS case in posix_lock_inode, presumably just by random luck since we're not actually initializing fl_flags here. This probably didn't matter before commit 7f024fcd5c97 ("Keep read and write fds with each nlm_file") since we wouldn't previously unlock unless we knew there were locks. But now it causes lockd to give up on removing more locks. We could just initialize fl_flags, but really it seems dubious to be calling vfs_lock_file with random values in some of the fields.

I thought I was iterating over the array when actually the iteration is over the values contained in the array? Ugh, keep it simple. Symptoms were a null deference in vfs_lock_file() when an NFSv3 client that previously held a lock came back up and sent a notify.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull signal/exit/ptrace updates from Eric Biederman: "This set of changes deletes some dead code, makes a lot of cleanups which hopefully make the code easier to follow, and fixes bugs found along the way. The end-game which I have not yet reached yet is for fatal signals that generate coredumps to be short-circuit deliverable from complete_signal, for force_siginfo_to_task not to require changing userspace configured signal delivery state, and for the ptrace stops to always happen in locations where we can guarantee on all architectures that the all of the registers are saved and available on the stack. Removal of profile_task_ext, profile_munmap, and profile_handoff_task are the big successes for dead code removal this round. A bunch of small bug fixes are included, as most of the issues reported were small enough that they would not affect bisection so I simply added the fixes and did not fold the fixes into the changes they were fixing. There was a bug that broke coredumps piped to systemd-coredump. I dropped the change that caused that bug and replaced it entirely with something much more restrained. Unfortunately that required some rebasing. Some successes after this set of changes: There are few enough calls to do_exit to audit in a reasonable amount of time. The lifetime of struct kthread now matches the lifetime of struct task, and the pointer to struct kthread is no longer stored in set_child_tid. The flag SIGNAL_GROUP_COREDUMP is removed.

2022-01-08nfs: block notification on fs with its own ->lockJ. Bruce Fields
NFSv4.1 supports an optional lock notification feature which notifies the client when a lock comes available. (Normally NFSv4 clients just poll for locks if necessary.) To make that work, we need to request a blocking lock from the filesystem. We turned that off for NFS in commit f657f8eef3ff ("nfs: don't atempt blocking locks on nfs reexports") [sic] because it actually blocks the nfsd thread while waiting for the lock. Thanks to Vasily Averin for pointing out that NFS isn't the only filesystem with that problem. Any filesystem that leaves ->lock NULL will use posix_lock_file(), which does the right thing. Simplest is just to assume that any filesystem that defines its own ->lock is not safe to request a blocking lock from. So, this patch mostly reverts commit f657f8eef3ff ("nfs: don't atempt blocking locks on nfs reexports") [sic] and commit b840be2f00c0 ("lockd: don't attempt blocking locks on nfs reexports"), and instead uses a check of ->lock (Vasily's suggestion) to decide whether to support blocking lock notifications on a given filesystem. Also add a little documentation. Perhaps someday we could add back an export flag later to allow filesystems with "good" ->lock methods to support blocking lock notifications.

2021-12-13lockd: use svc_set_num_threads() for thread start and stopNeilBrown
svc_set_num_threads() does everything that lockd_start_svc() does, except set sv_maxconn. It also (when passed 0) finds the threads and stops them with kthread_stop(). So move the setting for sv_maxconn, and use svc_set_num_thread() We now don't need nlmsvc_task. Now that we use svc_set_num_threads() it makes sense to set svo_module. This request that the thread exists with module_put_and_exit(). Also fix the documentation for svo_module to make this explicit. svc_prepare_thread is now only used where it is defined, so it can be made static.

2021-12-13lockd: rename lockd_create_svc() to lockd_get()NeilBrown
lockd_create_svc() already does an svc_get() if the service already exists, so it is more like a "get" than a "create". So: - Move the increment of nlmsvc_users into the function as well - rename to lockd_get(). It is now the inverse of lockd_put(). Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-12-13lockd: introduce lockd_put()NeilBrown
There is some cleanup that is duplicated in lockd_down() and the failure path of lockd_up(). Factor these out into a new lockd_put() and call it from both places. lockd_put() does *not* take the mutex - that must be held by the caller. It decrements nlmsvc_users and if that reaches zero, it cleans up. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-12-13lockd: move svc_exit_thread() into the threadNeilBrown
The normal place to call svc_exit_thread() is from the thread itself just before it exists. Do this for lockd. This means that nlmsvc_rqst is not used out side of lockd_start_svc(), so it can be made local to that function, and renamed to 'rqst'.

2021-12-13lockd: move lockd_start_svc() call into lockd_create_svc()NeilBrown
lockd_start_svc() only needs to be called once, just after the svc is created. If the start fails, the svc is discarded too. It thus makes sense to call lockd_start_svc() from lockd_create_svc(). This allows us to remove the test against nlmsvc_rqst at the start of lockd_start_svc() - it must always be NULL. lockd_up() only held an extra reference on the svc until a thread was created - then it dropped it. The thread - and thus the extra reference - will remain until kthread_stop() is called. Now that the thread is created in lockd_create_svc(), the extra reference can be dropped there. So the 'serv' variable is no longer needed in lockd_up(). Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-12-13lockd: simplify management of network status notifiersNeilBrown
Now that the network status notifiers use nlmsvc_serv rather then nlmsvc_rqst the management can be simplified. Notifier unregistration synchronises with any pending notifications so providing we unregister before nlm_serv is freed no further interlock is required. So we move the unregister call to just before the thread is killed (which destroys the service) and just before the service is destroyed in the failure-path of lockd_up(). Then nlm_ntf_refcnt and nlm_ntf_wq can be removed. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-12-13lockd: introduce nlmsvc_servNeilBrown
lockd has two globals - nlmsvc_task and nlmsvc_rqst - but mostly it wants the 'struct svc_serv', and when it doesn't want it exactly it can get to what it wants from the serv. This patch is a first step to removing nlmsvc_task and nlmsvc_rqst. It introduces nlmsvc_serv to store the 'struct svc_serv*'. This is set as soon as the serv is created, and cleared only when it is destroyed. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-12-13SUNRPC: stop using ->sv_nrthreads as a refcountNeilBrown
The use of sv_nrthreads as a general refcount results in clumsy code, as is seen by various comments needed to explain the situation. This patch introduces a 'struct kref' and uses that for reference counting, leaving sv_nrthreads to be a pure count of threads. The kref is managed particularly in svc_get() and svc_put(), and also nfsd_put(); svc_destroy() now takes a pointer to the embedded kref, rather than to the serv. nfsd allows the svc_serv to exist with ->sv_nrhtreads being zero. This happens when a transport is created before the first thread is started. To support this, a 'keep_active' flag is introduced which holds a ref on the svc_serv. This is set when any listening socket is successfully added (unless there are running threads), and cleared when the number of threads is set. So when the last thread exits, the nfs_serv will be destroyed. The use of 'keep_active' replaces previous code which checked if there were any permanent sockets. We no longer clear ->rq_server when nfsd() exits. This was done to prevent svc_exit_thread() from calling svc_destroy(). Instead we take an extra reference to the svc_serv to prevent svc_destroy() from being called. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-12-13SUNRPC/NFSD: clean up get/put functions.NeilBrown
svc_destroy() is poorly named - it doesn't necessarily destroy the svc, it might just reduce the ref count. nfsd_destroy() is poorly named for the same reason. This patch: - removes the refcount functionality from svc_destroy(), moving it to a new svc_put(). Almost all previous callers of svc_destroy() now call svc_put(). - renames nfsd_destroy() to nfsd_put() and improves the code, using the new svc_destroy() rather than svc_put() - removes a few comments that explain the important for balanced get/put calls. This should be obvious. The only non-trivial part of this is that svc_destroy() would call svc_sock_update() on a non-final decrement. It can no longer do that, and svc_put() isn't really a good place of it. This call is now made from svc_exit_thread() which seems like a good place. This makes the call *before* sv_nrthreads is decremented rather than after. This is not particularly important as the call just sets a flag which causes sv_nrthreads set be checked later. A subsequent patch will improve the ordering. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

2021-08-26lockd: don't attempt blocking locks on nfs reexportsJ. Bruce Fields
As in the v4 case, it doesn't work well to block waiting for a lock on an nfs filesystem. As in the v4 case, that means we're depending on the client to poll.
