2013-10-31NFSD: Add support for NFS v4.2 operation checkingAnna Schumaker1-0/+3
The server does allow NFS over v4.2, even if it doesn't add any new operations yet. I also switch to using constants to represent the last operation for each minor version since this makes the code cleaner and easier to understand at a quick glance.

2013-10-31percpu: fix this_cpu_sub() subtrahend casting for unsignedsGreg Thelen1-4/+4
this_cpu_sub() is implemented as negation and addition. This patch casts the adjustment to the counter type before negation to sign extend the adjustment. This helps in cases where the counter type is wider than an unsigned adjustment. An alternative to this patch is to declare such operations unsupported, but it seemed useful to avoid surprises. This patch specifically helps the following example: unsigned int delta = 1 preempt_disable() this_cpu_write(long_counter, 0) this_cpu_sub(long_counter, delta) preempt_enable() Before this change long_counter on a 64 bit machine ends with value 0xffffffff, rather than 0xffffffffffffffff. This is because this_cpu_sub(pcp, delta) boils down to this_cpu_add(pcp, -delta), which is basically: long_counter = 0 + 0xffffffff Also apply the same cast to: __this_cpu_sub() __this_cpu_sub_return() this_cpu_sub_return() All percpu_test.ko passes, especially the following cases which previously failed: l -= ui_one; __this_cpu_sub(long_counter, ui_one); CHECK(l, long_counter, -1); l -= ui_one; this_cpu_sub(long_counter, ui_one); CHECK(l, long_counter, -1); CHECK(l, long_counter, 0xffffffffffffffff); ul -= ui_one; __this_cpu_sub(ulong_counter, ui_one); CHECK(ul, ulong_counter, -1); CHECK(ul, ulong_counter, 0xffffffffffffffff); ul = this_cpu_sub_return(ulong_counter, ui_one); CHECK(ul, ulong_counter, 2); ul = __this_cpu_sub_return(ulong_counter, ui_one); CHECK(ul, ulong_counter, 1); Signed-off-by: Greg Thelen <gthelen@google.com> Acked-by: Tejun Heo <tj@kernel.org> Acked-by: Johannes Weiner <hannes@cmpxchg.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2013-10-30kvm: Create non-coherent DMA registerationAlex Williamson1-0/+19
We currently use some ad-hoc arch variables tied to legacy KVM device assignment to manage emulation of instructions that depend on whether non-coherent DMA is present. Create an interface for this, adapting legacy KVM device assignment and adding VFIO via the KVM-VFIO device. For now we assume that non-coherent DMA is possible any time we have a VFIO group. Eventually an interface can be developed as part of the VFIO external user interface to query the coherency of a group.

2013-10-30kvm: Add VFIO deviceAlex Williamson1-0/+1
So far we've succeeded at making KVM and VFIO mostly unaware of each other, but areas are cropping up where a connection beyond eventfds and irqfds needs to be made. This patch introduces a KVM-VFIO device that is meant to be a gateway for such interaction. The user creates the device and can add and remove VFIO groups to it via file descriptors. When a group is added, KVM verifies the group is valid and gets a reference to it via the VFIO external user interface.

2013-10-30padata: make the sequence counter an atomic_tMathias Krause1-2/+1
Using a spinlock to atomically increase a counter sounds wrong -- we've atomic_t for this! Also move 'seq_nr' to a different cache line than 'lock' to reduce cache line trashing. This has the nice side effect of decreasing the size of struct parallel_data from 192 to 128 bytes for a x86-64 build, e.g. occupying only two instead of three cache lines. Those changes results in a 5% performance increase on an IPsec test run using pcrypt. Btw. the seq_lock spinlock was never explicitly initialized -- one more reason to get rid of it.

2013-10-29uprobes: Teach uprobe_copy_process() to handle CLONE_VFORKOleg Nesterov1-2/+2
uprobe_copy_process() does nothing if the child shares ->mm with the forking process, but there is a special case: CLONE_VFORK. In this case it would be more correct to do dup_utask() but avoid dup_xol(). This is not that important, the child should not unwind its stack too much, this can corrupt the parent's stack, but at least we need this to allow to ret-probe __vfork() itself. Note: in theory, it would be better to check task_pt_regs(p)->sp instead of CLONE_VFORK, we need to dup_utask() if and only if the child can return from the function called by the parent. But this needs the arch-dependant helper, and I think that nobody actually does clone(same_stack, CLONE_VM).

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs into linux-next Pull fs-cache fixes from David Howells: Can you pull these commits to fix an issue with NFS whereby caching can be enabled on a file that is open for writing by subsequently opening it for reading. This can be made to crash by opening it for writing again if you're quick enough. The gist of the patchset is that the cookie should be acquired at inode creation only and subsequently enabled and disabled as appropriate (which dispenses with the backing objects when they're not needed). The extra synchronisation that NFS does can then be dispensed with as it is thenceforth managed by FS-Cache. Could you send these on to Linus? This likely will need fixing also in CIFS and 9P also once the FS-Cache changes are upstream.

This patch adds support for multiple security options which can be specified using a colon-delimited list of security flavors (the same syntax as nfsd's exports file). This is useful, for instance, when NFSv4.x mounts cross SECINFO boundaries.

2013-10-28NFS: Add method to retrieve fs_locations during migration recoveryChuck Lever1-0/+4
The nfs4_proc_fs_locations() function is invoked during referral processing to perform a GETATTR(fs_locations) on an object's parent directory in order to discover the target of the referral. It performs a LOOKUP in the compound, so the client needs to know the parent's file handle a priori. Unfortunately this function is not adequate for handling migration recovery. We need to probe fs_locations information on an FSID, but there's no parent directory available for many operations that can return NFS4ERR_MOVED. Another subtlety: recovering from NFS4ERR_LEASE_MOVED is a process of walking over a list of known FSIDs that reside on the server, and probing whether they have migrated. Once the server has detected that the client has probed all migrated file systems, it stops returning NFS4ERR_LEASE_MOVED. A minor version zero server needs to know what client ID is requesting fs_locations information so it can clear the flag that forces it to continue returning NFS4ERR_LEASE_MOVED. This flag is set per client ID and per FSID. However, the client ID is not an argument of either the PUTFH or GETATTR operations. Later minor versions have client ID information embedded in the compound's SEQUENCE operation. Therefore, by convention, minor version zero clients send a RENEW operation in the same compound as the GETATTR(fs_locations), since RENEW's one argument is a clientid4. This allows a minor version zero server to identify correctly the client that is probing for a migration.

2013-10-28mac80211: process the CSA frame for mesh accordinglyChun-Yeow Yeoh1-0/+20
Process the CSA frame according to the procedures define in IEEE Std 802.11-2012 section 10.9.8.4.3 as follow: * The mesh channel switch parameters element (MCSP) must be availabe. * If the MCSP's TTL is 1, drop the frame but still process the CSA. * If the MCSP's precedence value is less than or equal to the current precedence value, drop the frame and do not process the CSA. * The CSA frame is forwarded after TTL is decremented by 1 and the initiator field is set to 0. Transmit restrict field and others are maintained as is. * No beacon or probe response frame are handled here. Also, introduce the debug message used for mesh CSA purpose.

2013-10-28Merge tag 's3c24xx-dma' of ↵Olof Johansson7-63/+80
git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/drivers From Kukjin Kim, this branch adds device-tree support to the DMA controller on the older Samsung SoCs. It also adds support for one of the missing SoCs in the family (2410). The driver has been Ack:ed by Vinod Koul, but is merged through here due to dependencies with platform code. * tag 's3c24xx-dma' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: ARM: S3C24XX: add dma pdata for s3c2410, s3c2440 and s3c2442 dmaengine: s3c24xx-dma: add support for the s3c2410 type of controller ARM: S3C24XX: Fix possible dma selection warning ARM: SAMSUNG: set s3c24xx_dma_filter for s3c64xx-spi0 device ARM: S3C24XX: add platform-devices for new dma driver for s3c2412 and s3c2443 dmaengine: add driver for Samsung s3c24xx SoCs ARM: S3C24XX: number the dma clocks + Linux 3.12-rc3 Signed-off-by: Olof Johansson <olof@lixom.net>
