2016-02-02cputime: Prevent 32bit overflow in time[val|spec]_to_cputime()zengtao1-2/+3
The datatype __kernel_time_t is u32 on 32bit platform, so its subject to overflows in the timeval/timespec to cputime conversion. Currently the following functions are affected: 1. setitimer() 2. timer_create/timer_settime() 3. sys_clock_nanosleep This can happen on MIPS32 and ARM32 with "Full dynticks CPU time accounting" enabled, which is required for CONFIG_NO_HZ_FULL. Enforce u64 conversion to prevent the overflow.

2016-01-30block: revert runtime dax control of the raw block deviceDan Williams2-4/+0
Dynamically enabling DAX requires that the page cache first be flushed and invalidated. This must occur atomically with the change of DAX mode otherwise we confuse the fsync/msync tracking and violate data durability guarantees. Eliminate the possibilty of DAX-disabled to DAX-enabled transitions for now and revisit this for the next cycle.

2016-01-29ipv6: enforce flowi6_oif usage in ip6_dst_lookup_tail()Paolo Abeni1-2/+10
The current implementation of ip6_dst_lookup_tail basically ignore the egress ifindex match: if the saddr is set, ip6_route_output() purposefully ignores flowi6_oif, due to the commit d46a9d678e4c ("net: ipv6: Dont add RT6_LOOKUP_F_IFACE flag if saddr set"), if the saddr is 'any' the first route lookup in ip6_dst_lookup_tail fails, but upon failure a second lookup will be performed with saddr set, thus ignoring the ifindex constraint. This commit adds an output route lookup function variant, which allows the caller to specify lookup flags, and modify ip6_dst_lookup_tail() to enforce the ifindex match on the second lookup via said helper. ip6_route_output() becames now a static inline function build on top of ip6_route_output_flags(); as a side effect, out-of-tree modules need now a GPL license to access the output route lookup functionality.

2016-01-29target: Fix WRITE_SAME/DISCARD conversion to linux 512b sectorsMike Christie1-0/+3
In a couple places we are not converting to/from the Linux block layer 512 bytes sectors. 1. The request queue values and what we do are a mismatch of things: max_discard_sectors - This is in linux block layer 512 byte sectors. We are just copying this to max_unmap_lba_count. discard_granularity - This is in bytes. We are converting it to Linux block layer 512 byte sectors. discard_alignment - This is in bytes. We are just copying this over. The problem is that the core LIO code exports these values in spc_emulate_evpd_b0 and we use them to test request arguments in sbc_execute_unmap, but we never convert to the block size we export to the initiator. If we are not using 512 byte sectors then we are exporting the wrong values or are checks are off. And, for the discard_alignment/bytes case we are just plain messed up. 2. blkdev_issue_discard's start and number of sector arguments are supposed to be in linux block layer 512 byte sectors. We are currently passing in the values we get from the initiator which might be based on some other sector size. There is a similar problem in iblock_execute_write_same where the bio functions want values in 512 byte sectors but we are passing in what we got from the initiator.

2016-01-29workqueue: skip flush dependency checks for legacy workqueuesTejun Heo1-4/+5
fca839c00a12 ("workqueue: warn if memory reclaim tries to flush !WQ_MEM_RECLAIM workqueue") implemented flush dependency warning which triggers if a PF_MEMALLOC task or WQ_MEM_RECLAIM workqueue tries to flush a !WQ_MEM_RECLAIM workquee. This assumes that workqueues marked with WQ_MEM_RECLAIM sit in memory reclaim path and making it depend on something which may need more memory to make forward progress can lead to deadlocks. Unfortunately, workqueues created with the legacy create*_workqueue() interface always have WQ_MEM_RECLAIM regardless of whether they are depended upon memory reclaim or not.

After we use refcnt to check if transport is alive, the dead can be removed from sctp_transport. The traversal of transport_addr_list in procfs dump is using list_for_each_entry_rcu, no need to check if it has been freed. sctp_generate_t3_rtx_event and sctp_generate_heartbeat_event is protected by sock lock, it's not necessary to check dead, either. also, the timers are cancelled when sctp_transport_free() is called, that it doesn't wait for refcnt to reach 0 to cancel them.

2016-01-28sctp: fix the transport dead race check by using atomic_add_unless on refcntXin Long1-1/+1
Now when __sctp_lookup_association is running in BH, it will try to check if t->dead is set, but meanwhile other CPUs may be freeing this transport and this assoc and if it happens that __sctp_lookup_association checked t->dead a bit too early, it may think that the association is still good while it was already freed. So we fix this race by using atomic_add_unless in sctp_transport_hold. After we get one transport from hashtable, we will hold it only when this transport's refcnt is not 0, so that we can make sure t->asoc cannot be freed before we hold the asoc again. Note that sctp association is not freed using RCU so we can't use atomic_add_unless() with it as it may just be too late for that either.

2016-01-26irqdomain: Allow domain lookup with DOMAIN_BUS_WIRED tokenMarc Zyngier1-0/+1
Let's take the (outlandish) example of an interrupt controller capable of handling both wired interrupts and PCI MSIs. With the current code, the PCI MSI domain is going to be tagged with DOMAIN_BUS_PCI_MSI, and the wired domain with DOMAIN_BUS_ANY. Things get hairy when we start looking up the domain for a wired interrupt (typically when creating it based on some firmware information - DT or ACPI). In irq_create_fwspec_mapping(), we perform the lookup using DOMAIN_BUS_ANY, which is actually used as a wildcard. This gives us one chance out of two to end up with the wrong domain, and we try to configure a wired interrupt with the MSI domain. Everything grinds to a halt pretty quickly. What we really need to do is to start looking for a domain that would uniquely identify a wired interrupt domain, and only use DOMAIN_BUS_ANY as a fallback. In order to solve this, let's introduce a new DOMAIN_BUS_WIRED token, which is going to be used exactly as described above. Of course, this depends on the irqchip to setup the domain bus_token, and nobody had to implement this so far. Only so far.

2016-01-25drivers: ata: wake port before DMA stop for ALPMDanesh Petigara1-0/+1
The AHCI driver code stops and starts port DMA engines at will without considering the power state of the particular port. The AHCI specification isn't very clear on how to handle this scenario, leaving implementation open to interpretation. Broadcom's STB SATA host controller is unable to handle port DMA controller restarts when the port in question is in low power mode. When a port enters partial or slumber mode, its PHY is powered down. When a controller restart is requested, the controller's internal state machine expects the PHY to be brought back up by software which never happens in this case, resulting in failures. To avoid this situation, logic is added to manually wake up the port just before its DMA engine is stopped, if the port happens to be in a low power state. HBA initiated power management ensures that the port eventually returns to its configured low power state, when the link is idle (as per the conditions listed in the spec). A new host flag is also added to ensure this logic is only exercised for hosts with the above limitation. tj: Formatting changes.

2016-01-24net: simplify napi_synchronize() to avoid warningsArnd Bergmann1-6/+5
The napi_synchronize() function is defined twice: The definition for SMP builds waits for other CPUs to be done, while the uniprocessor variant just contains a barrier and ignores its argument. In the mvneta driver, this leads to a warning about an unused variable when we lookup the NAPI struct of another CPU and then don't use it: ethernet/marvell/mvneta.c: In function 'mvneta_percpu_notifier': ethernet/marvell/mvneta.c:2910:30: error: unused variable 'other_port' [-Werror=unused-variable] There are no other CPUs on a UP build, so that code never runs, but gcc does not know this. The nicest solution seems to be to turn the napi_synchronize() helper into an inline function for the UP case as well, as that leads gcc to not complain about the argument being unused. Once we do that, we can also combine the two cases into a single function definition and use if(IS_ENABLED()) rather than #ifdef to make it look a bit nicer. The warning first came up in linux-4.4, but I failed to catch it earlier.

git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rdma updates from Doug Ledford: "Initial roundup of 4.5 merge window patches - Remove usage of ib_query_device and instead store attributes in ib_device struct - Move iopoll out of block and into lib, rename to irqpoll, and use in several places in the rdma stack as our new completion queue polling library mechanism. Update the other block drivers that already used iopoll to use the new mechanism too. - Replace the per-entry GID table locks with a single GID table lock - IPoIB multicast cleanup - Cleanups to the IB MR facility - Add support for 64bit extended IB counters - Fix for netlink oops while parsing RDMA nl messages - RoCEv2 support for the core IB code - mlx4 RoCEv2 support - mlx5 RoCEv2 support - Cross Channel support for mlx5 - Timestamp support for mlx5 - Atomic support for mlx5 - Raw QP support for mlx5 - MAINTAINERS update for mlx4/mlx5 - Misc ocrdma, qib, nes, usNIC, cxgb3, cxgb4, mlx4, mlx5 updates - Add support for remote invalidate to the iSER driver (pushed through the RDMA tree due to dependencies, acknowledged by nab) - Update to NFSoRDMA (pushed through the RDMA tree due to dependencies, acknowledged by Bruce)" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (169 commits) IB/mlx5: Unify CQ create flags check IB/mlx5: Expose Raw Packet QP to user space consumers {IB, net}/mlx5: Move the modify QP operation table to mlx5_ib IB/mlx5: Support setting Ethernet priority for Raw Packet QPs IB/mlx5: Add Raw Packet QP query functionality IB/mlx5: Add create and destroy functionality for Raw Packet QP IB/mlx5: Refactor mlx5_ib_qp to accommodate other QP types IB/mlx5: Allocate a Transport Domain for each ucontext net/mlx5_core: Warn on unsupported events of QP/RQ/SQ net/mlx5_core: Add RQ and SQ event handling net/mlx5_core: Export transport objects IB/mlx5: Expose CQE version to user-space IB/mlx5: Add CQE version 1 support to user QPs and SRQs IB/mlx5: Fix data validation in mlx5_ib_alloc_ucontext IB/sa: Fix netlink local service GFP crash IB/srpt: Remove redundant wc array IB/qib: Improve ipoib UD performance IB/mlx4: Advertise RoCE v2 support IB/mlx4: Create and use another QP1 for RoCEv2 IB/mlx4: Enable send of RoCE QP1 packets with IP/UDP headers ...
2016-01-24MIPS: Add support for PIC32MZDA platformJoshua Henderson1-0/+22
This adds support for the Microchip PIC32 MIPS microcontroller with the specific variant PIC32MZDA. PIC32MZDA is based on the MIPS m14KEc core and boots using device tree. This includes an early pin setup and early clock setup needed prior to device tree being initialized. In additon, an interface is provided to synchronize access to registers shared across several peripherals.
