* nfs: make sillyrename an async operationJeff Layton2010-09-171-0/+19
| | | | | | | | | | | | | | | | | | A synchronous rename can be interrupted by a SIGKILL. If that happens during a sillyrename operation, it's possible for the rename call to be sent to the server, but the task exits before processing the reply. If this happens, the sillyrenamed file won't get cleaned up during nfs_dentry_iput and the server is left with a dangling .nfs* file hanging around. Fix this problem by turning sillyrename into an asynchronous operation and have the task doing the sillyrename just wait on the reply. If the task is killed before the sillyrename completes, it'll still proceed to completion.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* nfs: authenticated deep mountingEG Keizer2008-10-071-2/+8
| | | | | | | | | | | | | | | | | | | | | | | Allow mount to do authenticated mounts below the root of the exported tree. The wording in RFC 2623, sec 2.3.2. allows fsinfo with UNIX authentication on the root of the export. Mounts are not always done on the root of the exported tree. Especially autoumounts often mount below the root of the exported tree. Some server implementations (justly) require full authentication for the so-called deep mounts. The old code used AUTH_SYS only. This caused deep mounts to fail on systems requiring stronger authentication.. The client should try both authentication types and use the first one that succeeds. This method was already partially implemented. This patch completes the implementation for NFS2 and NFS3. This patch was developed to allow Debian systems to automount home directories on Solaris servers with krb5 authentication. Tested on kernel 2.6.24-etchnhalf.1 Signed-off-by: E.G.

* NFS: Add correct bounds checking to NFSv2 locksTrond Myklebust2008-07-091-0/+24
| | | | | | | | | | | | | | | | NFSv2 file locking currently fails the Connectathon tests, because the calls to the VFS locking code do not return an EINVAL error if the struct file_lock overflows the 32-bit boundaries. The problem is due to the fact that we occasionally call helpers from fs/locks.c in order to avoid RPC calls to the server when we know that a local process holds the lock. These helpers are, of course, always 64-bit enabled, so EINVAL is not returned in cases when it would if the call had gone to the NLM code. For consistency, we therefore add support for a bounds-checking helper. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NLM/NFS: Use cached nlm_host when calling nlmclnt_proc()Chuck Lever2008-01-301-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

To prevent other coding mistakes of this type, change the symlink proc API to be more like create/mkdir/mknod and move the nfs_instantiate call into the symlink proc routines so it is used in exactly the same way for create, mkdir, mknod, and symlink.

(*) Rearranged the function order within the files to be more logical and better grouped (IMO), though someone may prefer a different order. (*) Reduced the number of #ifdefs in .c files.

| | | | | | | | | | | | | | | | | | | When the client performs an exclusive create and opens the file for writing, a Netapp filer will first create the file using the mode 01777. It does this since an NFSv3/v4 exclusive create cannot immediately set the mode bits. The 01777 mode then gets put into the inode->i_mode. After the file creation is successful, we then do a setattr to change the mode to the correct value (as per the NFS spec). The problem is that nfs_refresh_inode() no longer updates inode->i_mode, so the latter retains the 01777 mode. A bit later, the VFS notices this, and calls remove_suid(). This of course now resets the file mode to inode->i_mode & 0777. Hey presto, the file mode on the server is now magically changed to 0777. Duh...
