2008-03-07[NET]: Make /proc/net a symlink on /proc/self/net (v3)Pavel Emelyanov4-37/+114
Current /proc/net is done with so called "shadows", but current implementation is broken and has little chances to get fixed. The problem is that dentries subtree of /proc/net directory has fancy revalidation rules to make processes living in different net namespaces see different entries in /proc/net subtree, but currently, tasks see in the /proc/net subdir the contents of any other namespace, depending on who opened the file first. The proposed fix is to turn /proc/net into a symlink, which points to /proc/self/net, which in turn shows what previously was in /proc/net - the network-related info, from the net namespace the appropriate task lives in. # ls -l /proc/net lrwxrwxrwx 1 root root 8 Mar 5 15:17 /proc/net -> self/net In other words - this behaves like /proc/mounts, but unlike "mounts", "net" is not a file, but a directory. Changes from v2: * Fixed discrepancy of /proc/net nlink count and selinux labeling screwup pointed out by Stephen. To get the correct nlink count the ->getattr callback for /proc/net is overridden to read one from the net->proc_net entry. To make selinux still work the net->proc_net entry is initialized properly, i.e. with the "net" name and the proc_net parent.

Merge include/linux/efs_fs{_i,_dir}.h into fs/efs/efs.h. efs_vh.h remains there because this is the IRIX volume header and shouldn't really be handled by efs but by the partitioning code. efs_sb.h remains there for now because it's exported to userspace.

2008-02-22Wrap buffers used for rpc debug printks into RPC_IFDEBUGPavel Emelyanov3-3/+3
Sorry for the noise, but here's the v3 of this compilation fix :) There are some places, which declare the char buf[...] on the stack to push it later into dprintk(). Since the dprintk sometimes (if the CONFIG_SYSCTL=n) becomes an empty do { } while (0) stub, these buffers cause gcc to produce appropriate warnings.

2008-02-21Remove empty file remnants that were left in the tree by mistakeLinus Torvalds1-0/+0
Noted by various people (Sam, Jeff, Roland..) Commit 58b7983d15a422d9616bdc4e245d5c31dfaefbe2 intended to remove the xfs "Makefile-linux-2.6" file, but it was mistakenly still left in the tree as a empty file, and would cause git to correctly complain about a tracked file being removed after a "make distclean" (which removes empty files as garbage). And the asm-x86/desc_64.h file was supposed to be removed by commit c81c6ca45a69478c7877b729af1942d2b80ef582, but instead stayed around containing just a single newline.

2008-02-20NFS: flush signals before taking down callback threadJeff Layton1-0/+1
Now that the reference counting on the callback thread is working as expected, it uncovers another problem. Peter Staubach noticed while testing that patch on an older kernel that he would occasionally see this printk in rpc_register fire: "RPC: failed to contact portmap (errno -512). The NFSv4 callback thread is signaled by nfs_callback_down(), but never flushes that signal. All of the shutdown processing is done with that signal pending. This makes it fail the call to unregister the port with the portmapper. In actuality, this rpc_register call isn't necessary at all since the port isn't actually registered with the portmapper anymore. Regardless, there doesn't seem to be any reason to leave the signal pending while the thread is being shut down and flushing it should generally silence that printk.

2008-02-14NFS: fix reference counting for NFSv4 callback threadJeff Layton1-6/+12
The reference counting for the NFSv4 callback thread stays artificially high. When this thread comes down, it doesn't properly tear down the svc_serv, causing a memory leak. In my testing on an older kernel on x86_64, memory would leak out of the 8k kmalloc slab. So, we're leaking at least a page of memory every time the thread comes down. svc_create() creates the svc_serv with a sv_nrthreads count of 1, and then svc_create_thread() increments that count. Whenever the callback thread is started it has a sv_nrthreads count of 2. When coming down, it calls svc_exit_thread() which decrements that count and if it hits 0, it tears everything down. That never happens here since the count is always at 2 when the thread exits. The problem is that nfs_callback_up() should be calling svc_destroy() on the svc_serv on both success and failure. This is how lockd_up_proto() handles the reference counting, and doing that here fixes the leak.

* 'for-linus' of git://linux-nfs.org/~bfields/linux: SUNPRC: Fix printk format warning nfsd: clean up svc_reserve_auth() NLM: don't requeue block if it was invalidated while GRANT_MSG was in flight NLM: don't reattempt GRANT_MSG when there is already an RPC in flight NLM: have server-side RPC clients default to soft RPC tasks NLM: set RPC_CLNT_CREATE_NOPING for NLM RPC clients
2008-02-11NLM: don't requeue block if it was invalidated while GRANT_MSG was in flightJeff Layton1-0/+11
It's possible for lockd to catch a SIGKILL while a GRANT_MSG callback is in flight. If this happens we don't want lockd to insert the block back into the nlm_blocked list. This helps that situation, but there's still a possible race. Fixing that will mean adding real locking for nlm_blocked. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: J.
