It's a useless abstraction for 'hlist_bl_head', and it doesn't actually help anything - quite the reverse. All the users end up having to know about the hlist_bl_head details anyway, using 'struct hlist_bl_node *' etc. So it just makes the code look confusing. And the cost of it is extra '&b->head' syntactic noise, but more importantly it spuriously makes the hash table dentry list look different from the per-superblock DCACHE_DISCONNECTED dentry list. As a result, the code ended up using ad-hoc locking for one case and special helper functions for what is really another totally identical case in the very same function. Make it all look and work the same. Signed-off-by:

Right now all RCU walks fall back to reference walk when CONFIG_SECURITY is enabled, even though just the standard capability module is active. This is because security_inode_exec_permission unconditionally fails RCU walks. Move this decision to the low level security module. This requires passing the RCU flags down the security hook. This way at least the capability module and a few easy cases in selinux/smack work with RCU walks with CONFIG_SECURITY=y Signed-off-by:

Andi Kleen pointed out that the Intel offcore support patches were merged without user-space tool support to the functionality: | | The offcore_msr perf kernel code was merged into 2.6.39-rc*, but the | user space bits were not. This made it impossible to set the extra mask | and actually do the OFFCORE profiling | Andi submitted a preliminary patch for user-space support, as an extension to perf's raw event syntax: | | Some raw events -- like the Intel OFFCORE events -- support additional | parameters. These can be appended after a ':'. | | For example on a multi socket Intel Nehalem: | | perf stat -e r1b7:20ff -a sleep 1 | | Profile the OFFCORE_RESPONSE.ANY_REQUEST with event mask REMOTE_DRAM_0 | that measures any access to DRAM on another socket. | But this kind of usability is absolutely unacceptable - users should not be expected to type in magic, CPU and model specific incantations to get access to useful hardware functionality. The proper solution is to expose useful offcore functionality via generalized events - that way users do not have to care which specific CPU model they are using, they can use the conceptual event and not some model specific quirky hexa number. We already have such generalization in place for CPU cache events, and it's all very extensible. "Offcore" events measure general DRAM access patters along various parameters. They are particularly useful in NUMA systems. We want to support them via generalized DRAM events: either as the fourth level of cache (after the last-level cache), or as a separate generalization category. That way user-space support would be very obvious, memory access profiling could be done via self-explanatory commands like: perf record -e dram ./myapp perf record -e dram-remote ./myapp ... to measure DRAM accesses or more expensive cross-node NUMA DRAM accesses. These generalized events would work on all CPUs and architectures that have comparable PMU features. ( Note, these are just examples: actual implementation could have more sophistication and more parameter - as long as they center around similarly simple usecases. ) Now we do not want to revert *all* of the current offcore bits, as they are still somewhat useful for generic last-level-cache events, implemented in this commit: e994d7d2: perf: Fix LLC-* events on Intel Nehalem/Westmere But we definitely do not yet want to expose the unstructured raw events to user-space, until better generalization and usability is implemented for these hardware event features. ( Note: after generalization has been implemented raw offcore events can be supported as well: there can always be an odd event that is marginally useful but not useful enough to generalize. DRAM profiling is definitely *not* such a category so generalization must be done first. ) Furthermore, PERF_TYPE_RAW access to these registers was not intended to go upstream without proper support - it was a side-effect of the above e994d7d2 commit, not mentioned in the changelog. As v2.6.39 is nearing release we go for the simplest approach: disable the PERF_TYPE_RAW offcore hack for now, before it escapes into a released kernel and becomes an ABI. Once proper structure is implemented for these hardware events and users are offered usable solutions we can revisit this issue. Reported-by:

check_events() implementations in both ide-gd and ide-cd are inadequate for in-kernel event polling. Both generate media change events continuously when certain conditions are met causing infinite event loop between the driver and userland event handler. As disk event now supports suppression of unlisted events, simply de-listing DISK_EVENT_MEDIA_CHANGE from disk->events resolves the problem. Internal handling around media revalidation will behave the same while userland will fall back to userland event polling after detecting the device doesn't support disk events. Signed-off-by:

DISK_EVENT_MEDIA_CHANGE is used for both userland visible event and internal event for revalidation of removeable devices. Some legacy drivers don't implement proper event detection and continuously generate events under certain circumstances. For example, ide-cd generates media changed continuously if there's no media in the drive, which can lead to infinite loop of events jumping back and forth between the driver and userland event handler. This patch updates disk event infrastructure such that it never propagates events not listed in disk->events to userland. Those events are processed the same for internal purposes but uevent generation is suppressed. This also ensures that userland only gets events which are advertised in the @events sysfs node lowering risk of confusion. Signed-off-by:

This call was disabled as hot-unplugging one virtconsole port led to another virtconsole port freezing. Upon testing it again, this now works, so enable it. In addition, a bug was found in qemu wherein removing a port of one type caused the guest output from another port to stop working. I doubt it was just this bug that caused it (since disabling the hvc_remove() call did allow other ports to continue working), but since it's all solved now, we're fine with hot-unplugging of virtconsole ports.

In the case where a virtio-console port is in use (opened by a program) and a virtio-console device is removed, the port is kept around but all the virtio-related state is assumed to be gone. When the port is finally released (close() called), we call device_destroy() on the port's device. This results in the parent device's structures to be freed as well. This includes the PCI regions for the virtio-console PCI device. Once this is done, however, virtio_pci_release_dev() kicks in, as the last ref to the virtio device is now gone, and attempts to do pci_iounmap(pci_dev, vp_dev->ioaddr); pci_release_regions(pci_dev); pci_disable_device(pci_dev); which results in a double-free warning. Move the code that releases regions, etc., to the virtio_pci_remove() function, and all that's now left in release_dev is the final freeing of the vp_dev. Signed-off-by:

Intel VT-d Protected Memory Regions (PMRs) are supposed to be disabled, on each VT-d engine, after DMA remapping is enabled on the engines. This is because the behavior of having both enabled is not deterministic and because, if TXT has been used to launch the kernel, the PMRs may be programmed to cover memory regions that will be used for DMA. Under some circumstances (certain quirks detected, lack of multiple devices, etc.), the current code does not set up DMA remapping on some VT-d engines. In such cases it also skips disabling the PMRs. This causes failures when the kernel is launched with TXT (most often this occurs on the graphics engine and results in colored vertical bars on the display). This patch detects when the kernel has been launched with TXT and then disables the PMRs on all VT-d engines. In some cases where the reason that remapping is not being enabled is due to possible ACPI DMAR table errors, the VT-d engine addresses may not be correct and thus not able to be safely programmed even to disable PMRs. Because part of the TXT launch process is the verification of these addresses, it will always be safe to disable PMRs if the TXT launch has succeeded and hence only doing this in such cases.

The cpu<->node mappings under CONFIG_DEBUG_PER_CPU_MAPS=y when NUMA emulation is enabled is currently broken because it does not iterate through every emulated node and bind cpus that have affinity to it. NUMA emulation should bind each cpu to every local node to accurately represent the true NUMA topology of the underlying machine. debug_cpumask_set_cpu() needs to be fixed at the same time so that the debugging information that it emits shows the new cpumask of the node being assigned when the cpu is being added or removed. It can now take responsibility of setting or clearing the cpu itself to remove the need for duplicate code. Also change its last parameter, "enable", to have the correct bool type since it can only be true or false. -v2: Fix the return statements, by Kosaki Motohiro Acked-and-Tested-by:

Andreas Herrmann reported that 7d6b4670 ("x86, NUMA: Fix fakenuma boot failure") causes certain physical NUMA topologies (for example AMD Magny-Cours) to move sibling cpus to a single node when in reality they are in separate domains. This may result in some nodes being completely void of cpus, which doesn't accurately represent the correct topology. The system will boot, but will have suboptimal NUMA performance. This commit was intended as a fix for NUMA emulation, but should not cause a regression for real NUMA machines as a side effect. ( There will be a separate fix for the numa-debug code, which will not affect physical topologies. ) Reported-by:

page_count is copied from userspace. agp_allocate_memory() tries to check whether this number is too big, but doesn't take into account the wrap case. Also agp_create_user_memory() doesn't check whether alloc_size is calculated from num_agp_pages variable without overflow. This may lead to allocation of too small buffer with following buffer overflow. Another problem in agp code is not addressed in the patch - kernel memory exhaustion (AGPIOC_RESERVE and AGPIOC_ALLOCATE ioctls). It is not checked whether requested pid is a pid of the caller (no check in agpioc_reserve_wrap()). Each allocation is limited to 16KB, though, there is no per-process limit. This might lead to OOM situation, which is not even solved in case of the caller death by OOM killer - the memory is allocated for another (faked) process. Signed-off-by:
