2010-05-28cnic: Fix context memory init. on 5709.Michael Chan2-9/+5
We need to zero context memory on 5709 in the function cnic_init_context(). Without this, iscsid restart on 5709 will not work because of stale data. TX context blocks should not be initialized by cnic_init_context() because of the special remapping on 5709. Update version to 2.1.2.

2010-05-28ipv6: Add GSO support on forwarding pathHerbert Xu1-1/+1
Currently we disallow GSO packets on the IPv6 forward path. This patch fixes this. Note that I discovered that our existing GSO MTU checks (e.g., IPv4 forwarding) are buggy in that they skip the check altogether, when they really should be checking gso_size + header instead. I have also been lazy here in that I haven't bothered to segment the GSO packet by hand before generating an ICMP message. Someone should add that to be 100% correct.

2010-05-28ALSA: hda: Use LPIB for Sony VPCS11V9EDaniel T Chen1-0/+1
BugLink: https://launchpad.net/bugs/586347 Symptom: On the Sony VPCS11V9E, using GStreamer-based applications with PulseAudio in Ubuntu 10.04 LTS results in stuttering audio. It appears to worsen with increased I/O. Test case: use Rhythmbox under increased I/O pressure. This symptom is reproducible in the current daily stable alsa-driver snapshots (at least up until 21 May 2010; later snapshots fail to build from source due to missing preprocessor directives when compiled against 2.6.32). Resolution: add SSID for this machine to the position_fix quirk table, explicitly specifying the LPIB method.

2010-05-27fs: introduce new truncate sequence[email protected]8-63/+300
Introduce a new truncate calling sequence into fs/mm subsystems. Rather than setattr > vmtruncate > truncate, have filesystems call their truncate sequence from ->setattr if filesystem specific operations are required. vmtruncate is deprecated, and truncate_pagecache and inode_newsize_ok helpers introduced previously should be used. simple_setattr is introduced for simple in-ram filesystems to implement the new truncate sequence. Eventually all filesystems should be converted to implement a setattr, and the default code in notify_change should go away. simple_setsize is also introduced to perform just the ATTR_SIZE portion of simple_setattr (ie. changing i_size and trimming pagecache). To implement the new truncate sequence: - filesystem specific manipulations (eg freeing blocks) must be done in the setattr method rather than ->truncate. - vmtruncate can not be used by core code to trim blocks past i_size in the event of write failure after allocation, so this must be performed in the fs code. - convert usage of helpers block_write_begin, nobh_write_begin, cont_write_begin, and *blockdev_direct_IO* to use _newtrunc postfixed variants. These avoid calling vmtruncate to trim blocks (see previous). - inode_setattr should not be used. generic_setattr is a new function to be used to copy simple attributes into the generic inode. - make use of the better opportunity to handle errors with the new sequence. Big problem with the previous calling sequence: the filesystem is not called until i_size has already changed. This means it is not allowed to fail the call, and also it does not know what the previous i_size was. Also, generic code calling vmtruncate to truncate allocated blocks in case of error had no good way to return a meaningful error (or, for example, atomically handle block deallocation).

2010-05-27fs/minix: bugfix, number of indirect block ptrs per block depends on block sizeErik van der Kouwe1-12/+15
The MINIX filesystem driver used a constant number of indirect block pointers in an indirect block. This worked only for filesystems with 1kb block, while the MINIX default block size is now 4kb. As a consequence, large files were read incorrectly on such filesystems and writing a large file would cause the filesystem to become corrupted. This patch computes the number of indirect block pointers based on the block size, making the driver work for each block size. I would like to thank Feiran Zheng ('Fam') for pointing out the cause of the corruption. Signed-off-by: Erik van der Kouwe <[email protected]> Signed-off-by: Al Viro <[email protected]>
2010-05-27rename the generic fsync implementationsChristoph Hellwig23-32/+44
We don't name our generic fsync implementations very well currently. The no-op implementation for in-memory filesystems currently is called simple_sync_file which doesn't make too much sense to start with, the the generic one for simple filesystems is called simple_fsync which can lead to some confusion. This patch renames the generic file fsync method to generic_file_fsync to match the other generic_file_* routines it is supposed to be used with, and the no-op implementation to noop_fsync to make it obvious what to expect. In addition add some documentation for both methods. Signed-off-by: Christoph Hellwig <[email protected]> Signed-off-by: Al Viro <[email protected]>

2010-05-27get rid of the magic around f_count in aioAl Viro4-15/+14
__aio_put_req() plays sick games with file refcount. What it wants is fput() from atomic context; it's almost always done with f_count > 1, so they only have to deal with delayed work in rare cases when their reference happens to be the last one. Current code decrements f_count and if it hasn't hit 0, everything is fine. Otherwise it keeps a pointer to struct file (with zero f_count!) around and has delayed work do __fput() on it. Better way to do it: use atomic_long_add_unless( , -1, 1) instead of !atomic_long_dec_and_test(). IOW, decrement it only if it's not the last reference, leave refcount alone if it was. And use normal fput() in delayed work. I've made that atomic_long_add_unless call a new helper - fput_atomic(). Drops a reference to file if it's safe to do in atomic (i.e. if that's not the last one), tells if it had been able to do that. aio.c converted to it, __fput() use is gone. req->ki_file *always* contributes to refcount now. And __fput() became static. Signed-off-by: Al Viro <[email protected]>
2010-05-27VFS: fix recent breakage of FS_REVAL_DOTNeil Brown1-1/+1
Commit 1f36f774b22a0ceb7dd33eca626746c81a97b6a5 broke FS_REVAL_DOT semantics. In particular, before this patch, the command ls -l in an NFS mounted directory would always check if the directory on the server had changed and if so would flush and refill the pagecache for the dir. After this patch, the same "ls -l" will repeatedly return stale date until the cached attributes for the directory time out. The following patch fixes this by ensuring the d_revalidate is called by do_last when "." is being looked-up. link_path_walk has already called d_revalidate, but in that case LOOKUP_OPEN is not set so nfs_lookup_verify_inode chooses not to do any validation. The following patch restores the original behaviour. Cc: [email protected] Signed-off-by: NeilBrown <[email protected]> Signed-off-by: Al Viro <[email protected]>
