commit 2d9e667e upstream. Certain revisions of this chipset appear to be broken. There is a shadow GTT which mirrors the real GTT but contains pre-translated physical addresses, for performance reasons. When a GTT update happens, the translations are done once and the resulting physical addresses written back to the shadow GTT. Except sometimes, the physical address is actually written back to the _real_ GTT, not the shadow GTT. Thus we start to see faults when that physical address is fed through translation again.

If another packet handler (like for AF_PACKET sockets) gets called first, the delivered skb will have a user count > 1, which causes pskb_may_pull to BUG halt when it does its skb_shared check. Fix this by calling skb_share_check prior to the may_pull call sites in the bonding driver to clone the skb when needed. Tested by myself and the reported successfully. Signed-off-by:

commit b433c3d4 upstream. Ilya reported that on a very slow machine he could reliably reproduce a race between forking init and kthreadd. We first fork init so that it obtains pid-1, however since the scheduler is already fully running at this point it can preempt and run the init thread before we spawn and set kthreadd_task. The init thread can then attempt spawning kthreads without kthreadd being present which results in an OOPS. Reported-by:

commit 9915672d upstream. Vegard Nossum found a unix socket OOM was possible, posting an exploit program. My analysis is we can eat all LOWMEM memory before unix_gc() being called from unix_release_sock(). Moreover, the thread blocked in unix_gc() can consume huge amount of time to perform cleanup because of huge working set. One way to handle this is to have a sensible limit on unix_tot_inflight, tested from wait_for_unix_gc() and to force a call to unix_gc() if this limit is hit. This solves the OOM and also reduce overall latencies, and should not slowdown normal workloads. Reported-by:

commit 25888e30 upstream. Its easy to eat all kernel memory and trigger NMI watchdog, using an exploit program that queues unix sockets on top of others. lkml ref : http://lkml.org/lkml/2010/11/25/8 This mechanism is used in applications, one choice we have is to have a recursion limit. Other limits might be needed as well (if we queue other types of files), since the passfd mechanism is currently limited by socket receive queue sizes only. Add a recursion_level to unix socket, allowing up to 4 levels. Each time we send an unix socket through sendfd mechanism, we copy its recursion level (plus one) to receiver. This recursion level is cleared when socket receive queue is emptied. Reported-by:

commit e508be17 upstream. Several users report issues with 32-bit adapters when plugged into PCI slots in machines with >= 4GB ram. In particular AMD systems with HyperTransport to PCI bridges seem to trigger the issue, but it isn't limited to only them. This issue is not easily reproducible here, yet still continues to occur in the field. For e1000 on PCI devices, just disable DMA addresses over the 4GB boundary when in PCI (not PCI-X) mode, to prevent the issue from continuing to pop up. The performance impact for this is negligible. The code was refactored to move the init of the hw struct to its own function. This allows the init to be called very early in probe, which then allows using hw-> members for this fix. A slight refactor to the DMA mask code was done for minor correctness based on the instructions in DMA-API-HOWTO. Signed-off-by:

commit 4c2ef25f upstream. If you don't use CONFIG_MMC_UNSAFE_RESUME, as soon as you attempt to suspend, the card will be removed, therefore this patch doesn't change the behavior of this option. However the removal will be done by pm notifier, which runs while userspace is still not frozen and thus can freely use del_gendisk, without the risk of deadlock which would happen otherwise. Card detect workqueue is now disabled while userspace is frozen, Therefore if you do use CONFIG_MMC_UNSAFE_RESUME, and remove the card during suspend, the removal will be detected as soon as userspace is unfrozen, again at the moment it is safe to call del_gendisk. Tested with and without CONFIG_MMC_UNSAFE_RESUME with suspend and hibernate.

commit d11c7add upstream. For Fedora, I want to force perf to link against libiberty.a for cplus_demangle, rather than libbfd.a for bfd_demangle due to licensing insanity on binutils. (libiberty is LGPL2, libbfd is GPL3.) If we just rely on autodetection, we'll end up with libbfd linked against us, since they're both in binutils-static in the buildroot.

commit b59a52f1 upstream. Use rt2x00dev->ops->extra_tx_headroom, not rt2x00dev->hw->extra_tx_headroom in the tx code, as the later may include other headroom not to be used in the chipset driver. Signed-off-by:

commit 7a4a77b7 upstream. Current rt2x00 drivers may result in a "ieee80211_tx_status: headroom too small" error message when a frame needs to be properly aligned before transmitting it. This is because the space needed to ensure proper alignment isn't requested from mac80211. Fix this by adding sufficient amount of alignment space to the amount of headroom requested for TX frames.

commit e6218cc4 upstream. Set the value of extra_tx_headroom in a central place, rather than in each of the drivers. This is preparatory for taking alignment space into account in the TX headroom requested by rt2x00. Signed-off-by:

commit d24deb25 upstream. Add a definition of the amount of TX headroom reserved by mac80211 itself for its own purposes. Also add BUILD_BUG_ON to validate the value. This define can then be used by drivers to request additional TX headroom in the most efficient manner. Signed-off-by:

commit 58eba97d upstream. virtio net will never try to overflow the TX ring, so the only reason add_buf may fail is out of memory. Thus, we can not stop the device until some request completes - there's no guarantee anything at all is outstanding. Make the error message clearer as well: error here does not indicate queue full.

commit 3e9d08ec upstream. Under harsh testing conditions, including low memory, the guest would stop receiving packets. With this patch applied we no longer see any problems in the driver while performing these tests for extended periods of time. Make sure napi is scheduled subsequent to each napi_enable.
