2007-05-11AFS: fix a couple of problems with unlinking AFS filesDavid Howells4-17/+31
Fix a couple of problems with unlinking AFS files. (1) The parent directory wasn't being updated properly between unlink() and the following lookup(). It seems that, for some reason, invalidate_remote_inode() wasn't discarding the directory contents correctly, so this patch calls invalidate_inode_pages2() instead on non-regular files. (2) afs_vnode_deleted_remotely() should handle vnodes that don't have a source server recorded without oopsing.

2007-05-10locks: fix F_GETLK regression (failure to find conflicts)J. Bruce Fields1-2/+3
In 9d6a8c5c213e34c475e72b245a8eb709258e968c we changed posix_test_lock to modify its single file_lock argument instead of taking separate input and output arguments. This makes it no longer safe to set the output lock's fl_type to F_UNLCK before looking for a conflict, since that means searching for a conflict against a lock with type F_UNLCK. This fixes a regression which causes F_GETLK to incorrectly report no conflict on most filesystems (including any filesystem that doesn't do its own locking). Also fix posix_lock_to_flock() to copy the lock type. This isn't strictly necessary, since the caller already does this; but it seems less likely to cause confusion in the future.

A small regression appears to have been introduced in the recent patch "cleanup compat ioctl handling", which was included in Linus' tree after 2.6.20. siocdevprivate_ioctl() is no longer defined if CONFIG_NET is undefined, whereas previously it was a dummy function in this case.

2007-05-09Add suspend-related notifications for CPU hotplugRafael J. Wysocki2-1/+4
Since nonboot CPUs are now disabled after tasks and devices have been frozen and the CPU hotplug infrastructure is used for this purpose, we need special CPU hotplug notifications that will help the CPU-hotplug-aware subsystems distinguish normal CPU hotplug events from CPU hotplug events related to a system-wide suspend or resume operation in progress. This patch introduces such notifications and causes them to be used during suspend and resume transitions. It also changes all of the CPU-hotplug-aware subsystems to take these notifications into consideration (for now they are handled in the same way as the corresponding "normal" ones).

2007-05-09fs: convert core functions to zero_user_pageNate Diller3-60/+19
It's very common for file systems to need to zero part or all of a page, the simplist way is just to use kmap_atomic() and memset(). There's actually a library function in include/linux/highmem.h that does exactly that, but it's confusingly named memclear_highpage_flush(), which is descriptive of *how* it does the work rather than what the *purpose* is. So this patchset renames the function to zero_user_page(), and calls it from the various places that currently open code it. This first patch introduces the new function call, and converts all the core kernel callsites, both the open-coded ones and the old memclear_highpage_flush() ones. Following this patch is a series of conversions for each file system individually, per AKPM, and finally a patch deprecating the old call. The diffstat below shows the entire patchset.

2007-05-09knfsd: avoid Oops if buggy userspace performs confusing filehandle->dentry ↵NeilBrown1-6/+50
mapping When a lookup request arrives, nfsd uses information provided by userspace (mountd) to find the right filesystem. It then assumes that the same filehandle type as the incoming filehandle can be used to create an outgoing filehandle. However if mountd is buggy, or maybe just being creative, the filesystem may not support that filesystem type, and the kernel could oops, particularly if 'ex_uuid' is NULL but a FSID_UUID* filehandle type is used. So add some proper checking that the fsid version/type from the incoming filehandle is actually supportable, and ignore that information if it isn't supportable.

So the length of the data part is the remainder of the head, plus page_len. 3/ other minor cleanups.

2007-05-09RPC: add wrapper for svc_reserve to account for checksumJeff Layton2-2/+2
When the kernel calls svc_reserve to downsize the expected size of an RPC reply, it fails to account for the possibility of a checksum at the end of the packet. If a client mounts a NFSv2/3 with sec=krb5i/p, and does I/O then you'll generally see messages similar to this in the server's ring buffer: RPC request reserved 164 but used 208 While I was never able to verify it, I suspect that this problem is also the root cause of some oopses I've seen under these conditions: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=227726 This is probably also a problem for other sec= types and for NFSv4. The large reserved size for NFSv4 compound packets seems to generally paper over the problem, however. This patch adds a wrapper for svc_reserve that accounts for the possibility of a checksum. It also fixes up the appropriate callers of svc_reserve to call the wrapper. For now, it just uses a hardcoded value that I determined via testing. That value may need to be revised upward as things change, or we may want to eventually add a new auth_op that attempts to calculate this somehow. Unfortunately, there doesn't seem to be a good way to reliably determine the expected checksum length prior to actually calculating it, particularly with schemes like spkm3.

2007-05-09The NFSv2/NFSv3 server does not handle zero length WRITE requests correctlyPeter Staubach2-17/+77
The NFSv2 and NFSv3 servers do not handle WRITE requests for 0 bytes correctly. The specifications indicate that the server should accept the request, but it should mostly turn into a no-op. Currently, the server will return an XDR decode error, which it should not. Attached is a patch which addresses this issue. It also adds some boundary checking to ensure that the request contains as much data as was requested to be written. It also correctly handles an NFSv3 request which requests to write more data than the server has stated that it is prepared to handle. Previously, there was some support which looked like it should work, but wasn't quite right.

2007-05-09AFS: implement basic file write supportDavid Howells11-27/+1483
Implement support for writing to regular AFS files, including: (1) write (2) truncate (3) fsync, fdatasync (4) chmod, chown, chgrp, utime. AFS writeback attempts to batch writes into as chunks as large as it can manage up to the point that it writes back 65535 pages in one chunk or it meets a locked page. Furthermore, if a page has been written to using a particular key, then should another write to that page use some other key, the first write will be flushed before the second is allowed to take place. If the first write fails due to a security error, then the page will be scrapped and reread before the second write takes place. If a page is dirty and the callback on it is broken by the server, then the dirty data is not discarded (same behaviour as NFS). Shared-writable mappings are not supported by this patch.

2007-05-08smaps: only define clear_refs for CONFIG_MMUDavid Rientjes1-0/+2
/proc/pid/clear_refs is only defined in the CONFIG_MMU case, so make sure we don't have any references to clear_refs_smap() in generic procfs code.

2007-05-08udf: support files larger than 1GJan Kara3-82/+180
Make UDF work correctly for files larger than 1GB. As no extent can be longer than (1<<30)-blocksize bytes, we have to create several extents if a big hole is being created. As a side-effect, we now don't discard preallocated blocks when creating a hole.
