2009-06-29tty: Fix the leak in tty_ldisc_releaseAlan Cox
Currently we reinit the ldisc on final tty close which is what the old code did to ensure that if the device retained its termios settings then it had the right ldisc. tty_ldisc_reinit does that but also leaves us with the reset ldisc reference which is then leaked. At this point we know the port will be recycled so we can kill the ldisc off completely rather than try and add another ldisc free up when the kref count hits zero. At this point it is safe to keep the ldisc closed as tty_ldisc waiting methods are only used from the user side, and as the final close we are the last such reference. Interrupt/driver side methods will always use the non wait version and get back a NULL. Found with kmemleak and investigated/identified by Catalin Marinas.

2009-06-28be2net: Fix to avoid a crash seen on PPC with LRO and Jumbo frames.Ajit Khaparde
While testing the driver on PPC, we ran into a crash with LRO, Jumbo frames. With CONFIG_PPC_64K_PAGES configured (a default in PPC), MAX_SKB_FRAGS drops to 3 and we were crossing the array limits on skb_shinfo(skb)->frags[]. Now we coalesce the frags from the same physical page into one slot in skb_shinfo(skb)->frags[] and go to the next index when the frag is from different physical page. This patch is against the net-2.6 tree. Signed-off-by: Ajit Khaparde <ajitk@serverengines.com> Signed-off-by: David S. Miller <davem@davemloft.net>

I think this is the best solution since user programs are only supposed to look at sysfs to determine how much can be mapped, and libbsr does this as well.

The macio_dev's created to map devices inside the MacIO ASICs don't have proper dma_ops.

2009-06-26ACPI: video: prevent NULL deref in acpi_get_pci_dev()Troy Moure
ref: http://thread.gmane.org/gmane.linux.kernel/857228/focus=857468 When the ACPI video driver initializes, it does a namespace walk looking for for supported devices. When we find an appropriate handle, we walk up the ACPI tree looking for a PCI root bus, and then walk back down the PCI bus, assuming that every device inbetween is a P2P bridge. This assumption is not correct, and is reported broken on at least: Dell Latitude E6400 ThinkPad X61 Dell XPS M1330 Add a NULL deref check to prevent boot panics.

2009-06-26eeepc-laptop: Register as a pci-hotplug deviceCorentin Chary
The eee contains a logically (but not physically) hotpluggable PCIe slot. Currently this is handled by adding or removing the PCI device in response to rfkill events, but if a user has forced pciehp to bind to it (with the force=1 argument) then both drivers will try to handle the event and hilarity (in the form of oopses) will ensue. This can be avoided by having eee-laptop register the slot as a hotplug slot. Only one of pciehp and eee-laptop will successfully register this, avoiding the problem.

This commit 335f8514f200e63d689113d29cb7253a5c282967 has stopped properly checking if there is any usb serial associated with the tty in the close function. It happens the close function is called by releasing the terminal right after opening the device fails. As an example, open fails with a non-existing device, when probe has never been called, because the device has never been plugged. This is common in systems with static modules and no udev.

2009-06-24Staging: octeon-ethernet: Fix race freeing transmit buffers.David Daney
The existing code had the following race: Thread-1 Thread-2 inc/read in_use inc/read in_use inc tx_free_list[qos].len inc tx_free_list[qos].len The actual in_use value was incremented twice, but thread-1 is going to free memory based on its stale value, and will free one too many times. The result is that memory is freed back to the kernel while its packet is still in the transmit buffer. If the memory is overwritten before it is transmitted, the hardware will put a valid checksum on it and send it out (just like it does with good packets). If by chance the TCP flags are clobbered but not the addresses or ports, the result can be a broken TCP stream. The fix is to track the number of freed packets in a single location (a Fetch-and-Add Unit register). That way it can never get out of sync with itself. We try to free up to MAX_SKB_TO_FREE (currently 10) buffers at a time. If fewer are available we adjust the free count with the difference. The action of claiming buffers to free is atomic so two threads cannot claim the same buffers. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-06-24Staging: octeon-ethernet: Convert to use net_device_ops.David Daney
Convert the driver to use net_device_ops as it is now mandatory. Also compensate for the removal of struct sk_buff's dst field. The changes are mostly mechanical, the content of ethernet-common.c was moved to ethernet.c and ethernet-common.{c,h} are removed.

This patch does not change actual behaviour since dma_unmap_page is just an alias of dma_unmap_single on MIPS.

2009-06-24tty: fix tty_port_block_til_ready waitingJiri Slaby
Since commit 3e3b5c087799e536871c8261b05bc28e4783c8da ("tty: use prepare/finish_wait"), tty_port_block_til_ready() is using prepare_to_wait()/finish_wait(). Those functions require that the wait_queue_t be initialised with .func=autoremove_wake_function, via DEFINE_WAIT(). But the conversion from DECLARE_WAITQUEUE() to DEFINE_WAIT() was not made, so this code will oops in finish_wait().
