2017-02-23sunvdc: Add support for setting physical sector sizeLiam R. Howlett
Physical sector size is supported in v1.2 of the vDisk protocol and should be set if available. If protocol version 1.2 is used and the physical disk size is unavailable, then the disk is considered busy. Signed-off-by: Liam R. Howlett <Liam.Howlett@Oracle.com> Signed-off-by: David S.

2017-02-23sparc64: fix for user probes in high memoryEric Saint Etienne
When returning from the user probe code into userspace process, PC & NPC are truncated to 32 bits. Due to shared libraries getting loaded very high in the virtual address space of the process, placing a user probe inside a shared library makes the kernel return into the process at the wrong address, causing it to seg'fault most of the time. This patch prevents truncating PC and NPC. Signed-off-by: Eric Saint Etienne <eric.saint.etienne@oracle.com> Reviewed-by: David Aldridge <david.j.aldridge@oracle.com> Signed-off-by: David S.

The objects viking_ops, viking_sun4d_smp_ops and smp_cachetlb_ops of type sparc32_cachetlb_ops are not modified anywhere after getting modified in the init functions. Inside init their reference is also stored in a pointer of type const struct sparc32_cachetlb_ops *.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for your net tree, they are: 1) Revisit warning logic when not applying default helper assignment. Jiri Kosina considers we are breaking existing setups and not warning our users accordinly now that automatic helper assignment has been turned off by default. So let's make him happy by spotting the warning by when we find a helper but we cannot attach, instead of warning on the former deprecated behaviour. Patch from Jiri Kosina. 2) Two patches to fix regression in ctnetlink interfaces with nfnetlink_queue. Specifically, perform more relaxed in CTA_STATUS and do not bail out if CTA_HELP indicates the same helper that we already have. Patches from Kevin Cernekee. 3) A couple of bugfixes for ipset via Jozsef Kadlecsik. Due to wrong index logic in hash set types and null pointer exception in the list:set type. 4) hashlimit bails out with correct userspace parameters due to wrong arithmetics in the code that avoids "divide by zero" when transforming the userspace timing in milliseconds to token credits. Patch from Alban Browaeys. 5) Fix incorrect NFQA_VLAN_MAX definition, patch from Ken-ichirou MATSUZAWA. 6) Don't not declare nfnetlink batch error list as static, since this may be used by several subsystems at the same time.

2017-02-23net/mlx4_core: Use cq quota in SRIOV when creating completion EQsJack Morgenstein
When creating EQs to handle CQ completion events for the PF or for VFs, we create enough EQE entries to handle completions for the max number of CQs that can use that EQ. When SRIOV is activated, the max number of CQs a VF (or the PF) can obtain is its CQ quota (determined by the Hypervisor resource tracker). Therefore, when creating an EQ, the number of EQE entries that the VF should request for that EQ is the CQ quota value (and not the total number of CQs available in the FW). Under SRIOV, the PF, also must use its CQ quota, because the resource tracker also controls how many CQs the PF can obtain. Using the FW total CQs instead of the CQ quota when creating EQs resulted wasting MTT entries, due to allocating more EQEs than were needed.

2017-02-23net/mlx5e: Fix wrong CQE decompressionTariq Toukan
In cqe compression with striding RQ, the decompression of the CQE field wqe_counter was done with a wrong wraparound value. This caused handling cqes with a wrong pointer to wqe (rx descriptor) and creating SKBs with wrong data, pointing to wrong (and already consumed) strides/pages. The meaning of the CQE field wqe_counter in striding RQ holds the stride index instead of the WQE index. Hence, when decompressing a CQE, wqe_counter should have wrapped-around the number of strides in a single multi-packet WQE. We dropped this wrap-around mask at all in CQE decompression of striding RQ. It is not needed as in such cases the CQE compression session would break because of different value of wqe_id field, starting a new compression session. Tested: ethtool -K ethxx lro off/on ethtool --set-priv-flags ethxx rx_cqe_compress on super_netperf 16 {ipv4,ipv6} -t TCP_STREAM -m 50 -D verified no csum errors and no page refcount issues.

2017-02-23net/mlx5e: Update MPWQE stride size when modifying CQE compress stateSaeed Mahameed
When the admin enables/disables cqe compression, updating mpwqe stride size is required: CQE compress ON ==> stride size = 256B CQE compress OFF ==> stride size = 64B This is already done on driver load via mlx5e_set_rq_type_params, all we need is just to call it on arbitrary admin changes of cqe compression state via priv flags or when changing timestamping state (as it is mutually exclusive with cqe compression). This bug introduces no functional damage, it only makes cqe compression occur less often, since in ConnectX4-LX CQE compression is performed only on packets smaller than stride size. Tested: ethtool --set-priv-flags ethxx rx_cqe_compress on pktgen with 64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6) verify `ethtool -S ethxx | grep compress` are advancing more often (rapidly) Fixes: 7219ab34f184 ("net/mlx5e: CQE compression") Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Reviewed-by: Tariq Toukan <tariqt@mellanox.com> Cc: kernel-team@fb.com Signed-off-by: David S.

2017-02-23net/mlx5e: Fix broken CQE compression initializationTariq Toukan
Some of RQ type parameters are derived from CQE compression state flag, CQE compression flag was initialized only after RQ type parameters setup. This leads to load RQ with stride size smaller than what we want for when CQE compression is on. This bug introduces no functional damage, it only makes CQE compression occur less often, since in ConnectX4-LX CQE compression is performed only on packets smaller than stride size. Fix this by marking default status of CQE compression in PFLAG prior to calling mlx5e_set_rq_priv_params(), as it inits some fields based on it. Tested: load driver on systems where rx CQE compress will be on (MH) pktgen with 64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6) verify `ethtool -S ethxx | grep compress` are advancing more often (rapidly) Fixes: 2fc4bfb7250d ("net/mlx5e: Dynamic RQ type infrastructure") Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Cc: kernel-team@fb.com Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: David S.

Pull KVM updates from Paolo Bonzini: "4.11 is going to be a relatively large release for KVM, with a little over 200 commits and noteworthy changes for most architectures. ARM: - GICv3 save/restore - cache flushing fixes - working MSI injection for GICv3 ITS - physical timer emulation MIPS: - various improvements under the hood - support for SMP guests - a large rewrite of MMU emulation. KVM MIPS can now use MMU notifiers to support copy-on-write, KSM, idle page tracking, swapping, ballooning and everything else. KVM_CAP_READONLY_MEM is also supported, so that writes to some memory regions can be treated as MMIO. The new MMU also paves the way for hardware virtualization support.

git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk Pull printk updates from Petr Mladek: - Add Petr Mladek, Sergey Senozhatsky as printk maintainers, and Steven Rostedt as the printk reviewer. This idea came up after the discussion about printk issues at Kernel Summit. It was formulated and discussed at lkml[1]. - Extend a lock-less NMI per-cpu buffers idea to handle recursive printk() calls by Sergey Senozhatsky[2]. It is the first step in sanitizing printk as discussed at Kernel Summit. The change allows to see messages that would normally get ignored or would cause a deadlock. Also it allows to enable lockdep in printk(). This already paid off. The testing in linux-next helped to discover two old problems that were hidden before[3][4]. - Remove unused parameter by Sergey Senozhatsky. Clean up after a past change.

2017-02-22mm/z3fold.c: limit first_num to the actual range of possible buddy indexeszhong jiang
At present, Tying the first_num size to NCHUNKS_ORDER is confusing. the number of chunks is completely unrelated to the number of buddies. The patch limits the first_num to actual range of possible buddy indexes. and that is more reasonable and obvious without functional change.

2017-02-22zram: remove obsolete sysfs attrsSergey Senozhatsky
We had a deprecated_attr_warn() warning for 2 years and now the time has come and we finally can do the cleanup. The plan was as follows: : per-stat sysfs attributes are considered to be deprecated. : The basic strategy is: : -- the existing RW nodes will be downgraded to WO nodes (in linux 4.11) : -- deprecated RO sysfs nodes will eventually be removed (in linux 4.11) : : The list of deprecated attributes can be found here: : Documentation/ABI/obsolete/sysfs-block-zram : : Basically, every attribute that has its own read accessible sysfs : node (e.g. num_reads) *AND* is accessible via one of the stat files : (zram<id>/stat or zram<id>/io_stat or zram<id>/mm_stat) is considered : to be deprecated. The patch also removes `obsolete/sysfs-block-zram', clean ups `testing/sysfs-block-zram' and tweaks zram.txt files.
