2007-11-29sysfs: fix off-by-one error in fill_read_buffer()Miao Xie1-1/+5
I found that there is a off-by-one problem in the following code. Version: 2.6.24-rc2 File: fs/sysfs/file.c:118-122 Function: fill_read_buffer -------------------------------------------------------------------- count = ops->show(kobj, attr_sd->s_attr.attr, buffer->page); sysfs_put_active_two(attr_sd); BUG_ON(count > (ssize_t)PAGE_SIZE); -------------------------------------------------------------------- Because according to the specification of the sysfs and the implement of the show methods, the show methods return the number of bytes which would be generated for the given input, excluding the trailing null.So if the return value of the show methods equals PAGE_SIZE - 1, the buffer is full in fact. And if the return value equals PAGE_SIZE, the resulting string was already truncated,or buffer overflow occurred. This patch fixes an off-by-one error in fill_read_buffer.

2007-11-29create /sys/.../power when CONFIG_PM is setDaniel Drake4-16/+27
The CONFIG_SUSPEND changes in 2.6.23 caused a regression under certain configuration conditions (SUSPEND=n, USB_AUTOSUSPEND=y) where all USB device attributes in sysfs (idVendor, idProduct, ...) silently disappeared, causing udev breakage and more. The cause of this is that the /sys/.../power subdirectory is now only created when CONFIG_PM_SLEEP is set, however, it should be created whenever CONFIG_PM is set to handle the above situation. The following patch fixes the regression. Signed-off-by: Daniel Drake <dsd@gentoo.org> Acked-by: Rafael J.

2007-11-28prep_zero_page: remove bogus BUG_ONHugh Dickins1-1/+0
2.6.11 gave __GFP_ZERO's prep_zero_page a bogus "highmem may have to wait" assertion. Presumably added under the misconception that clear_highpage uses nonatomic kmap; but then and now it uses kmap_atomic, so no problem.

2007-11-28ocfs2: reverse inline-data truncate argsMark Fasheh1-4/+15
ocfs2_truncate() and ocfs2_remove_inode_range() had reversed their "set i_size" arguments to ocfs2_truncate_inline(). Fix things so that truncate sets i_size, and punching a hole ignores it. This exposed a problem where punching a hole in an inline-data file wasn't updating the page cache, so fix that too. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2007-11-28ocfs2: Remove bug statement in ocfs2_dentry_iput()Mark Fasheh1-4/+16
The existing bug statement didn't take into account unhashed dentries which might not have a cluster lock on them. This could happen if a node exporting the file system via NFS is rebooted, re-exported to nfs clients and then unmounted. It's fine in this case to not have a dentry cluster lock. Just remove the bug statement and replace it with an error print, which does the proper checks. Though we want to know if something has happened which might have prevented a cluster lock from being created, it's definitely not necessary to panic the machine for this.

If the inode block isn't valid then we don't want to print the value from that, instead print the block number which was passed in (which should always be correct). Also, turn this into a debug print for now - folks who hit an actual problem always have other logs indicating what the source is. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2007-11-28IPoIB: Fix oops if xmit is called when priv->broadcast is NULLJack Morgenstein1-0/+3
If a port goes down, ipoib_ib_dev_down() is invoked -- which flushes the mcasts (clearing priv->broadcast) and clearing the path record cache. If ipoib_start_xmit() is then invoked (before the broadcast group is rejoined), a kernel oops results from attempting to access priv->broadcast, which is still unset. Returning NULL from path_rec_create() if priv->broadcast is NULL is a harmless way of bypassing the problem -- the offending packet is simply discarded "without prejudice."
