This reverts commit c02e3f36 ("kmod: fix race in usermodehelper code") The patch is wrong. UMH_WAIT_EXEC is called with VFORK what ensures that the child finishes prior returing back to the parent. No race. In fact, the patch makes it even worse because it does the thing it claims not do: - It calls ->complete() on UMH_WAIT_EXEC - the complete() callback may de-allocated subinfo as seen in the following call chain: [<c009f904>] (__link_path_walk+0x20/0xeb4) from [<c00a094c>] (path_walk+0x48/0x94) [<c00a094c>] (path_walk+0x48/0x94) from [<c00a0a34>] (do_path_lookup+0x24/0x4c) [<c00a0a34>] (do_path_lookup+0x24/0x4c) from [<c00a158c>] (do_filp_open+0xa4/0x83c) [<c00a158c>] (do_filp_open+0xa4/0x83c) from [<c009ba90>] (open_exec+0x24/0xe0) [<c009ba90>] (open_exec+0x24/0xe0) from [<c009bfa8>] (do_execve+0x7c/0x2e4) [<c009bfa8>] (do_execve+0x7c/0x2e4) from [<c0026a80>] (kernel_execve+0x34/0x80) [<c0026a80>] (kernel_execve+0x34/0x80) from [<c004b514>] (____call_usermodehelper+0x130/0x148) [<c004b514>] (____call_usermodehelper+0x130/0x148) from [<c0024858>] (kernel_thread_exit+0x0/0x8) and the path pointer was NULL. Good that ARM's kernel_execve() doesn't check the pointer for NULL or else I wouldn't notice it. The only race there might be is with UMH_NO_WAIT but it is too late for me to investigate it now. UMH_WAIT_PROC could probably also use VFORK and we could save one exec. So the only race I see is with UMH_NO_WAIT and recent scheduler changes where the child does not always run first might have trigger here something but as I said, it is late.... Signed-off-by:

This patch gets around that by propagating the NFS_OPTION_FSCACHE flag across automounts. If a uniquifier is supplied to a mount then this is propagated to all automounts of that mount too.

[[resending with correct cc: - "vfs.kernel.org" just isn't right!]] xprt->reestablish_timeout is used to cause TCP connection attempts to back off if the connection fails so as not to hammer the network, but to still allow immediate connections when there is no reason to believe there is a problem. It is not used for the first connection (when transport->sock is NULL) but only on reconnects. It is currently set: a/ to 0 when xs_tcp_state_change finds a state of TCP_FIN_WAIT1 on the assumption that the client has closed the connection so the reconnect should be immediate when needed. b/ to at least XS_TCP_INIT_REEST_TO when xs_tcp_state_change detects TCP_CLOSING or TCP_CLOSE_WAIT on the assumption that the server closed the connection so a small delay at least is required. c/ as above when xs_tcp_state_change detects TCP_SYN_SENT, so that it is never 0 while a connection has been attempted, else the doubling will produce 0 and there will be no backoff. d/ to double is value (up to a limit) when delaying a connection, thus providing exponential backoff and e/ to XS_TCP_INIT_REEST_TO in xs_setup_tcp as simple initialisation. So you can see it is highly dependant on xs_tcp_state_change being called as expected. However experimental evidence shows that xs_tcp_state_change does not see all state changes. ("rpcdebug -m rpc trans" can help show what actually happens). Results show: TCP_ESTABLISHED is reported when a connection is made. TCP_SYN_SENT is never reported, so rule 'c' above is never effective. When the server closes the connection, TCP_CLOSE_WAIT and TCP_LAST_ACK *might* be reported, and TCP_CLOSE is always reported. This rule 'b' above will sometimes be effective, but not reliably. When the client closes the connection, it used to result in TCP_FIN_WAIT1, TCP_FIN_WAIT2, TCP_CLOSE. However since commit f75e6745 (SUNRPC: Fix the problem of EADDRNOTAVAIL syslog floods on reconnect) we don't see *any* events on client-close. I think this is because xs_restore_old_callbacks is called to disconnect xs_tcp_state_change before the socket is closed. In any case, rule 'a' no longer applies. So all that is left are rule d, which successfully doubles the timeout which is never rest, and rule e which initialises the timeout. Even if the rules worked as expected, there would be a problem because a successful connection does not reset the timeout, so a sequence of events where the server closes the connection (e.g. during failover testing) will cause longer and longer timeouts with no good reason. This patch: - sets reestablish_timeout to 0 in xs_close thus effecting rule 'a' - sets it to 0 in xs_tcp_data_ready to ensure that a successful connection resets the timeout - sets it to at least XS_TCP_INIT_REEST_TO after it is doubled, thus effecting rule c I have not reimplemented rule b and the new version of rule c seems sufficient. I suspect other code in xs_tcp_data_ready needs to be revised as well. For example I don't think connect_cookie is being incremented as often as it should be. Signed-off-by:

The security_ops reset done when SELinux is disabled at run time is done after the avc cache is freed and after the kmem_cache for the avc is also freed. This means that between the time the selinux disable code destroys the avc_node_cachep another process could make a security request and could try to allocate from the cache. We are just going to leave the cachep around, like we always have. SELinux: Disabled at runtime.

The key garbage collector sets a timer to start a new collection cycle at the point the earliest key to expire should be considered garbage. However, it currently only does this if the key it is considering hasn't yet expired. If the key being considering has expired, but hasn't yet reached the collection time then it is ignored, and won't be collected until some other key provokes a round of collection. Make the garbage collector set the timer for the earliest key that hasn't yet passed its collection time, rather than the earliest key that hasn't yet expired. Signed-off-by:

This patch adds a persistent, read-only caching facility for 9p clients using the FS-Cache caching backend. When the fscache facility is enabled, each inode is associated with a corresponding vcookie which is an index into the FS-Cache indexing tree. The FS-Cache indexing tree is indexed at 3 levels: - session object associated with each mount. - inode/vcookie - actual data (pages) A cache tag is chosen randomly for each session. These tags can be read off /sys/fs/9p/caches and can be passed as a mount-time parameter to re-attach to the specified caching session. Signed-off-by:
