There's no reason for a mutex here, except to allow an allocation under the lock, which we can avoid with the usual trick of preallocating memory for the new object and freeing it if it turns out to be unnecessary. Signed-off-by: NJ. Bruce Fields <bfields@citi.umich.edu>

The sm_count is decremented to zero but left on the nsm_handles list. So in the space between decrementing sm_count and acquiring nsm_mutex, it is possible for another task to find this nsm_handle, increment the use count and then enter nsm_release itself. Thus there's nothing to prevent the nsm being freed before we acquire nsm_mutex here. Signed-off-by: NJ. Bruce Fields <bfields@citi.umich.edu>

As far as I can tell, selecting the CRYPTO and CRYPTO_MD5 entries under CONFIG_NFSD is redundant, since CONFIG_NFSD_V4 already selects RPCSEC_GSS_KRB5, which selects these entries. Testing with "make menuconfig" shows that the entries under CRYPTO still properly reflect "Y" or "M" based on the setting of CONFIG_NFSD after this change is applied.

Likewise, distros usually leave CONFIG_NFSD_TCP enabled. TCP support in the Linux NFS server is stable enough that we can leave it on always. CONFIG_NFSD_TCP adds about 10 lines of code, and defaults to "Y" anyway. Signed-off-by: NChuck Lever <chuck.lever@oracle.com> Signed-off-by: NJ. Bruce Fields <bfields@citi.umich.edu>

The code here is difficult to understand; attempt to clarify somewhat by pulling out one of the more mystifying conditionals into a separate function.

Have lockd_up start lockd using kthread_run. With this change, lockd_down now blocks until lockd actually exits, so there's no longer need for the waitqueue code at the end of lockd_down. This also means that only one lockd can be running at a time which simplifies the code within lockd's main loop. This also adds a check for kthread_should_stop in the main loop of nlmsvc_retry_blocked and after that function returns. There's no sense continuing to retry blocks if lockd is coming down anyway.

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....

[mszeredi@suse.cz] rewrite and split big patch into managable chunks /proc/mounts in its current form lacks important information: - propagation state - root of mount for bind mounts - the st_dev value used within the filesystem - identifier for each mount and it's parent It also suffers from the following problems: - not easily extendable - ambiguity of mountpoints within a chrooted environment - doesn't distinguish between filesystem dependent and independent options - doesn't distinguish between per mount and per super block options This patch introduces /proc/<pid>/mountinfo which attempts to address all these deficiencies. Code shared between /proc/<pid>/mounts and /proc/<pid>/mountinfo is extracted into separate functions. Thanks to Al Viro for the help in getting the design right.

Allow /proc/<pid>/mountinfo to use the root of <pid> to calculate mountpoints. - move definition of 'struct proc_mounts' to <linux/mnt_namespace.h> - add the process's namespace and root to this structure - pass a pointer to 'struct proc_mounts' into seq_operations In addition the following cleanups are made: - use a common open function for /proc/<pid>/{mounts,mountstat} - surround namespace.c part of these proc files with #ifdef CONFIG_PROC_FS - make the seq_operations structures const Signed-off-by: NMiklos Szeredi <mszeredi@suse.cz> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

Add a unique ID to each peer group using the IDR infrastructure. The identifiers are reused after the peer group dissolves. The IDR structures are protected by holding namepspace_sem for write while allocating or deallocating IDs. IDs are allocated when a previously unshared vfsmount becomes the first member of a peer group. When a new member is added to an existing group, the ID is copied from one of the old members. IDs are freed when the last member of a peer group is unshared. Setting the MNT_SHARED flag on members of a subtree is done as a separate step, after all the IDs have been allocated. This way an allocation failure can be cleaned up easilty, without affecting the propagation state. Based on design sketch by Al Viro.

Taking namespace_sem shared there isn't worth the trouble, especially with vfsmount ID allocation about to be added. That way we know that umount_tree(), copy_tree() and clone_mnt() are _always_ serialized by namespace_sem. umount_tree() still needs vfsmount_lock (it manipulates hash chains, among other things), but that's a separate story.
