Here is a little optimisation for the cb_lock used by netlink_dump. While fixing that race earlier, I noticed that the reference count held by cb_lock is completely useless. The reason is that in order to obtain the protection of the reference count, you have to take the cb_lock. But the only way to take the cb_lock is through dereferencing the socket. That is, you must already possess a reference count on the socket before you can take advantage of the reference count held by cb_lock. As a corollary, we can remve the reference count held by the cb_lock. Signed-off-by:

htb_enqueue(): Free skb and return NET_XMIT_DROP if a packet is destined for the direct_queue but the direct_queue is full. (Before this: erroneously returned NET_XMIT_SUCCESS even though the packet was not enqueued) Signed-off-by:

kfree() and vfree() can both deal with NULL pointers. This patch removes redundant NULL pointer checks from the ppp code in drivers/net/ Signed-off-by:

kfree(0) is perfectly valid, checking pointers for NULL before calling kfree() on them is redundant. The patch below cleans away a few such redundant checks (and while I was around some of those bits I couldn't stop myself from making a few tiny whitespace changes as well). Signed-off-by:

Converts rtm_min and rtm_max arrays to use c99 designated initializers for easier insertion of new message families. RTM_GETMULTICAST and RTM_GETANYCAST did not have the minimal message size specified which means that the netlink message was parsed for routing attributes starting from the header. Adds the proper minimal message sizes for these messages (netlink header + common rtnetlink header) to fix this issue. Signed-off-by:

Thomas Graf authored
RTM_MAX is currently set to the maximum reserverd message type plus one thus being the cause of two bugs for new types being assigned a) given the new family registers only the NEW command in its reserved block the array size for per family entries is calculated one entry short and b) given the new family registers all commands RTM_MAX would point to the first entry of the block following this one and the rtnetlink receive path would accept a message type for a nonexisting family. This patch changes RTM_MAX to point to the maximum valid message type by aligning it to the start of the next block and subtracting one. Signed-off-by:

Herbert Xu authored
I made a mistake in my last patch to the raw socket checksum code. I used the value of inet->cork.length as the length of the payload. While this works with normal packets, it breaks down when IPsec is present since the cork length includes the extension header length. So here is a patch to fix the length calculations.

gcc-4.0 generates altivec code implicitly when -mcpu indicates an altivec capable CPU which is not suitable for the kernel. However, we used to set -mcpu=970 when CONFIG_ALTIVEC was set because a gcc-3.x bug prevented from using -maltivec along with -mcpu=power4, thus prevented building the RAID6 altivec code. This patch fixes all of this by testing for the gcc version. If 4.0 or later, just normally use -mcpu=power4 and let the RAID6 code add -maltivec to the few files it needs to be compiled with altivec support. For 3.x, we still use -mcpu=970 to work around the above problem, which is fine as 3.x will never implicitly generate altivec code. The Makefile hackery may not be the most lovely, I welcome anybody more skilled than me to improve it. Signed-off-by:

This patch adds jfs_syncpt, which calls lmLogSync to write sync points to the journal both in jfs_sync_fs and when sync barrier processing completes. lmLogSync accomplishes two things: 1) it pushes logged-but-dirty metadata pages to disk, and 2) it writes a sync record to the journal so that jfs_fsck doesn't need to replay more transactions than is necessary.

JFS code has always assumed a page size of 4K. This patch fixes the non-pagecache uses of pages to deal with larger pages. Signed-off-by:
-
Dave Kleikamp authored
JFS was creating a new IAG (inode aggregate group) in one address space, and afterwards, accessing it from another. This could lead to complications when cache pages contain more than one page of jfs metadata. This patch causes the IAG to be initialized in the same address space that it is subsequently accessed with. This also elimitates an I/O, but IAG's aren't created too often. Signed-off-by:

Use an inline pxd list rather than an xad list in the xadlock. When the number of extents being modified can fit with the xadlock, a transaction can be committed asynchronously. Using a list of pxd's instead of xad's allows us to fit 4 extents, rather than 2. Signed-off-by:

The cpufreq core patch I sent earlier got only half-applied. I added a flag to let the low level driver disable an annoying warning on suspend/resume that is normal on ppc, but the "resume" part of it wasn't applied. This just adds back that missing bit. The original patch also reworked the resume() function to avoid nesting too many if () statements along the way I did the suspend() one, but I didn't include that in the patch below. Signed-off-by:

The clock spreading disable/enable code was called to late/early during the suspend/resume code on some laptops and would trigger a might_sleep() warning due to the down() call in the low level i2c code. This fixes it by calling those functions earlier/later when interrupts are still enabled. Signed-off-by:

A typo in the machine table incorrectly mark the 101 PowerBook as needing explicit callback from the video driver to enable sleep mode. I did not implement that mecanism for chipsest older than r128, so we need to mark this machine as always beeing able to sleep for now. Signed-off-by:

We are experiencing a problem when flushing the CPU caches before sleep on some laptop models using the 750FX CPU rev 1.X. While I haven't been able to figure out a proper explanation for what's going on, I do have a workaround that seem to work reliably and allows those machine to sleep and wakeup properly again. I'll re-update that code if/when I ever find exactly what is happening with those CPU revisions. Signed-off-by:
