2008-02-14Embed a struct path into struct nameidata instead of nd->{dentry,mnt}Jan Blunck
This is the central patch of a cleanup series. In most cases there is no good reason why someone would want to use a dentry for itself. This series reflects that fact and embeds a struct path into nameidata. Together with the other patches of this series - it enforced the correct order of getting/releasing the reference count on <dentry,vfsmount> pairs - it prepares the VFS for stacking support since it is essential to have a struct path in every place where the stack can be traversed - it reduces the overall code size: without patch series: text data bss dec hex filename 5321639 858418 715768 6895825 6938d1 vmlinux with patch series: text data bss dec hex filename 5320026 858418 715768 6894212 693284 vmlinux This patch: Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

2008-02-07NFS: Fix a potential file corruption issue when writingTrond Myklebust
If the inode is flagged as having an invalid mapping, then we can't rely on the PageUptodate() flag. Ensure that we don't use the "anti-fragmentation" write optimisation in nfs_updatepage(), since that will cause NFS to write out areas of the page that are no longer guaranteed to be up to date. A potential corruption could occur in the following scenario: client 1 client 2 =============== =============== fd=open("f",O_CREAT|O_WRONLY,0644); write(fd,"fubar\n",6); // cache last page close(fd); fd=open("f",O_WRONLY|O_APPEND); write(fd,"foo\n",4); close(fd); fd=open("f",O_WRONLY|O_APPEND); write(fd,"bar\n",4); close(fd); ----- The bug may lead to the file "f" reading 'fubar\n\0\0\0\nbar\n' because client 2 does not update the cached page after re-opening the file for write. Instead it keeps it marked as PageUptodate() until someone calls invaldate_inode_pages2() (typically by calling read()). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2008-02-05Pagecache zeroing: zero_user_segment, zero_user_segments and zero_userChristoph Lameter
Simplify page cache zeroing of segments of pages through 3 functions zero_user_segments(page, start1, end1, start2, end2) Zeros two segments of the page. It takes the position where to start and end the zeroing which avoids length calculations and makes code clearer. zero_user_segment(page, start, end) Same for a single segment. zero_user(page, start, length) Length variant for the case where we know the length. We remove the zero_user_page macro. Issues: 1. Its a macro. Inline functions are preferable. 2. The KM_USER0 macro is only defined for HIGHMEM. Having to treat this special case everywhere makes the code needlessly complex. The parameter for zeroing is always KM_USER0 except in one single case that we open code. Avoiding KM_USER0 makes a lot of code not having to be dealing with the special casing for HIGHMEM anymore. Dealing with kmap is only necessary for HIGHMEM configurations. In those configurations we use KM_USER0 like we do for a series of other functions defined in highmem.h. Since KM_USER0 is depends on HIGHMEM the existing zero_user_page function could not be a macro. zero_user_* functions introduced here can be be inline because that constant is not used when these functions are called. Also extract the flushing of the caches to be outside of the kmap.

2008-01-30NFS: Address memory leaks in the NFS client mount option parserChuck Lever
David Howells noticed that repeating the same mount option twice during an NFS mount request can result in orphaned memory in certain cases. Only the client_address and mount_server.hostname strings are initialized in the mount parsing loop, so those appear to be the only two pointers that might be written over by repeating a mount option. The strings in the nfs_server section of the nfs_parsed_mount_data structure are set only once after the options are parsed, thus these are not susceptible to being overwritten.

2008-01-30NFS: Optimise away the sigmask code in aio/dio reads and writesTrond Myklebust
There are no interruptible waits for asynchronous RPC tasks, so we don't need to wrap calls to rpc_run_task() with an rpc_clnt_sigmask/rpc_clnt_unsigmask pair. Instead we can wrap the wait_for_completion_interruptible() in nfs_direct_wait(). This means that we completely optimise away sigmask setting for the case of non-blocking aio/dio.

2008-01-30NLM/NFS: Use cached nlm_host when calling nlmclnt_proc()Chuck Lever
Now that each NFS mount point caches its own nlm_host structure, it can be passed to nlmclnt_proc() for each lock request. By pinning an nlm_host for each mount point, we trade the overhead of looking up or creating a fresh nlm_host struct during every NLM procedure call for a little extra memory. We also restrict the nlmclnt_proc symbol to limit the use of this call to in-tree modules. Note that nlm_lookup_host() (just removed from the client's per-request NLM processing) could also trigger an nlm_host garbage collection. Now client-side nlm_host garbage collection occurs only during NFS mount processing. Since the NFS client now holds a reference on these nlm_host structures, they wouldn't have been affected by garbage collection anyway. Given that nlm_lookup_host() reorders the global nlm_host chain after every successful lookup, and that a garbage collection could be triggered during the call, we've removed a significant amount of per-NLM-request CPU processing overhead. Sidebar: there are only a few remaining references to the internals of NFS inodes in the client-side NLM code. The only references I found are related to extracting or comparing the inode's file handle via NFS_FH(). One is in nlmclnt_grant(); the other is in nlmclnt_setlockargs().
