* firewire: normalize style of queue_work wrappersStefan Richter2009-10-14
| | | | | | | | | | | | | | | | | A few stylistic changes to unify some code patterns in the subsystem: - The similar queue_delayed_work helpers fw_schedule_bm_work, schedule_iso_resource, and sbp2_queue_work now have the same call convention. - Two conditional calls of schedule_iso_resource are factored into another small helper. - An sbp2_target_get helper is added as counterpart to sbp2_target_put. Object size of firewire-core is decreased a little bit, object size of firewire-sbp2 remains unchanged. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: sbp2: provide fallback if mgt_ORB_timeout is missingStefan Richter2009-10-14
| | | | | | | | | | | | | | The Unit_Characteristics entry of an SBP-2 unit directory is not mandatory as far as I can tell. If it is missing, we would probably fail to log in into the target because firewire-sbp2 would not wait for status after it sent the login request. The fix moves the cleanup of tgt->mgt_orb_timeout into a place where it is executed exactly once before login, rather than 0..n times depending on the target's config ROM. With targets with one or more Unit_Characteristics entries, the result is the same as before. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: core: fix race with parallel PCI device probeStefan Richter2009-09-12
| | | | | | | | | | | | | | The config ROM buffer received from generate_config_rom is a globally shared static buffer. Extend the card_mutex protection in fw_add_card until after the config ROM was copied into the card driver's buffer. Otherwise, parallelized card driver probes may end up with ROM contents that were meant for a different card. firewire-ohci's card->driver->enable hook is safe to be called within the card_mutex. Furthermore, it is safe to reorder card_list update versus card enable, which simplifies the code a little. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: ohci: fix Self ID Count register mask (safeguard against buffer ↵Stefan Richter2009-09-12
| | | | | | | | | | | | | | | | | | | | | | overflow) The selfIDSize field of Self ID Count is 9 bits wide, and we are only interested in the high 8 bits. Fix the mask accordingly. The previously too large mask didn't do damage though because the next few bits in the register are reserved and therefore zero with presently existing hardware. Also, check for the maximum possible self ID count of 252 (according to OHCI 1.1 clause 11.2 and IEEE 1394a-2000 clause 4.3.4.1, i.e. up to four self IDs of up to 63 nodes, even though IEEE 1394 up to edition 2008 defines only up to three self IDs per node). More than 252 self IDs would only happen if the self ID receive DMA unit malfunctioned, which would likely be caught by other self ID buffer checks. However, check it early to be sure. More than 253 quadlets would overflow the Topology Map CSR. Reported-By: PaX Team Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* i915: disable interrupts before tearing down GEM stateLinus Torvalds2009-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reinette Chatre reports a frozen system (with blinking keyboard LEDs) when switching from graphics mode to the text console, or when suspending (which does the same thing). With netconsole, the oops turned out to be BUG: unable to handle kernel NULL pointer dereference at 0000000000000084 IP: [<ffffffffa03ecaab>] i915_driver_irq_handler+0x26b/0xd20 [i915] and it's due to the i915_gem.c code doing drm_irq_uninstall() after having done i915_gem_idle(). And the i915_gem_idle() path will do i915_gem_idle() -> i915_gem_cleanup_ringbuffer() -> i915_gem_cleanup_hws() -> dev_priv->hw_status_page = NULL; but if an i915 interrupt comes in after this stage, it may want to access that hw_status_page, and gets the above NULL pointer dereference. And since the NULL pointer dereference happens from within an interrupt, and with the screen still in graphics mode, the common end result is simply a silently hung machine. Fix it by simply uninstalling the irq handler before idling rather than after.

After a short while, no IR IRQ events occur and the context control register does not react anymore. This happens regardless whether both IR DMA contexts are dual-buffer or one is dual-buffer and the other packet-per-buffer. This can be worked around by disabling dual buffer DMA mode entirely. http://sourceforge.net/mailarchive/message.php?msg_name=4A7C0594.2020208%40gmail.com (Reported by Samuel Audet.) In another report (by Jonathan Cameron), an FW643 works OK with two cameras in dual buffer mode. Whether this is due to different chip revisions or different usage patterns (different video formats) is not yet clear. However, as far as the current capabilities of firewire-core's isochronous I/O interface are concerned, simply switching off dual-buffer on non-working and working FW643s alike is not a problem in practice. We only need to revisit this issue if we are going to enhance the interface, e.g. so that applications can explicitly choose modes.

But blk_queue_max_sectors() differs a bit 1. It sets both max_sectors_kb, and max_hw_sectors_kb 2. Never allows one to change max_sectors_kb above BLK_DEF_MAX_SECTORS. If one specifies a value greater then max_hw_sectors is set to that value but max_sectors is set to BLK_DEF_MAX_SECTORS I am not sure whether blk_queue_max_sectors() should be changed, as it seems to be that way for a long time. And there may be callers dependent on that behaviour. This patch simply reverts to the older way of directly assigning the value to max_sectors as it was before.

In this case, we have to use the default ID to allow the driver to load.

And when a qdisc gets reset, that's exactly what we need to do here. We'll work this out in the net-next-2.6 tree and if warranted we'll backport that work to -stable.

But in some cases sk_free() is called earlier, usually after other alloc errors. Fix is to move sk_wmem_alloc initialization from sock_init_data() to sk_alloc() itself.
