From: Andy Whitcroft <apw@shadowen.org> The sysctl interfaces for updating the uts entries such as hostname and domainname are using the wrong length for these buffers; they are hard coded to 64. Although safe, this artifically limits the size of these fields to one less than the true maximum. This generates an inconsistency between the various methods of update for these fields. # hostname 12345678901234567890123456789012345678901234567890123456789012345 hostname: name too long # hostname 1234567890123456789012345678901234567890123456789012345678901234 # hostname 1234567890123456789012345678901234567890123456789012345678901234 # sysctl -w kernel.hostname=1234567890123456789012345678901234567890123456789012345678901234567890 kernel.hostname = 1234567890123456789012345678901234567890123456789012345678901234567890 # hostname 123456789012345678901234567890123456789012345678901234567890123 # The error originates from the fact the handler for strings (proc_dostring) already allows for the string terminator.

From: john stultz <johnstul@us.ibm.com> In testing for SLES9, we ran across a bug caused by userspace apps poking the PIT which caused bad values to be read by the kernel. This would then trigger the lost tick detection code with insane values and would then break the SCSI subsystem. This patch includes the PIT sanity check from the TSC timesource into the cyclone timesource code, which catches the bad case described above and resolves the issue. Signed-off-by:

From: Martin Schwidefsky <schwidefsky@de.ibm.com> This patch adds support for 6 system call arguments on s390. The first exploiter of this will be the sys_futex system call for the FUTEX_CMP_REQUEUE operation. The idea is simple: use register %r7 for the 6th argument. This can be extended to 7/8/9/... arguments if there ever will be the need for it. To call the system call function in the kernel the additional arguments needs to get stored on the stack. 8 bytes are added to the head of struct pt_regs. %r7 is stored to the additional field for all system calls. The store is hidden in a address-generation-interlock slot, it doesn't slow down the system call path. Signed-off-by:

From: Jens Axboe <axboe@suse.de> cdrom_has_defect_mgt() has the same ->data_len bug - the length field is not total length, but the length following that field. So it should be + 4, not + 8. However, just kill the length check. Comparison of feature_code provides enough check. Signed-off-by:

From: NeilBrown <neilb@cse.unsw.edu.au> This condtion on this loop is primarily to avoid the loop if it doesn't appear to be needed. However it optimises a little too much and there is a case where it skips the loop when it is really needed. This patch fixes it. This is the raid6 version of the recent raid5 resync bugfix.

From: Christoph Hellwig <hch@lst.de> drivers/block/paride/epat.c support two slightly different protocol variants. Currently it's compile-time selected by CONFIG_PARIDE_EPATC8, but this patch adds a epatc8 module option to allow runtime selection. CONFIG_PARIDE_EPATC8 stays for now but I'd like to kill it int 2.7. The basic patch is from the Debian kernel package (Author unknown) but I reworked it a bit. Signed-off-by:

The ____cacheline_aligned in there is a leftover from before the existence of the percpu infrastructure. It bloats struct page_state and structures which contain it enormously, and we use these things on the stack deep in page reclaim. Signed-off-by:

From: Chris Mason <mason@suse.com> There's a small window where the filesystem can be unmounted during writeback_inodes. The end result is the iput done by sync_sb_inodes could be done after the FS put_super and and the super has been removed from all lists. The fix is to hold the s_umount sem during sync_sb_inodes to make sure the FS doesn't get unmounted. Signed-off-by:

Fix a problem discovered by Jeff Mahoney <jeffm@suse.com>, based on an initial patch from Chris Mason <mason@suse.com>. journal_get_descriptor_buffer() is used to obtain a regular old buffer_head against the blockdev mapping. The caller will populate that bh by hand and will then submit it for writing. But there are problems: a) The function sets bh->b_state nonatomically. But this buffer is accessible to other CPUs via pagecache lookup. b) The function sets the buffer dirty and then the caller populates it and then it is submitted for I/O. Wrong order: there's a window in which the VM could write the buffer before it is fully populated. c) The function fails to set the buffer uptodate after zeroing it. And one caller forgot to mark it uptodate as well. So if the VM happens to decide to write the containing page back __block_write_full_page() encounters a dirty, not uptodate buffer, which is an illegal state. This was generating buffer_error() warnings before we removed buffer_error(). Leaving the buffer not uptodate also means that a concurrent reader of /dev/hda1 could cause physical I/O against the buffer, scribbling on what we just put in it. So journal_get_descriptor_buffer() is changed to mark the buffer uptodate, under the buffer lock. I considered changing journal_get_descriptor_buffer() to return a locked buffer but there doesn't seem to be a need for this, and both callers end up using ll_rw_block() anyway, which requires that the buffer be unlocked again. Note that the journal_get_descriptor_buffer() callers dirty these buffers with set_buffer_dirty(). That's a bit naughty, because it could create dirty buffers against a clean page - an illegal state. They really should use mark_buffer_dirty() to dirty the page and inode as well. But all callers will immediately write and clean the buffer anyway, so we can safely leave this optimising cheat in place. Signed-off-by:

"Gee it works better if you turn the chip on before programming it" The ioctl to ethtool change broke that little detail... I made the changes, Jeff agreed in principle, Red Hat owns them and I know no reason they can't be contributed under the GPL v2 or later. Requires: ethtool change

Several ethernet drivers have been broken by the ethtool support because the ioctl code used to power the interface up and down as needed. Rather than add this to each driver call Jeff Garzik suggested we add hooks for before/after ethtool processing. This patch implements them which makes fixing the PM stuff easier, as the epic100 patch to follow will show. It also cleans up the via-velocity driver pm/ethtool logic a great deal. As per Jeff's request the before handler is allowed to fail the operation. -- The contribution herein included is a creation of Red Hat Inc.
