2017-05-01dm bufio: check new buffer allocation watermark every 30 secondsMikulas Patocka
dm-bufio checks a watermark when it allocates a new buffer in __bufio_new(). However, it doesn't check the watermark when the user changes /sys/module/dm_bufio/parameters/max_cache_size_bytes. This may result in a problem - if the watermark is high enough so that all possible buffers are allocated and if the user lowers the value of "max_cache_size_bytes", the watermark will never be checked against the new value because no new buffer would be allocated. To fix this, change __evict_old_buffers() so that it checks the watermark. __evict_old_buffers() is called every 30 seconds, so if the user reduces "max_cache_size_bytes", dm-bufio will react to this change within 30 seconds and decrease memory consumption.

2017-05-01dm bufio: avoid a possible ABBA deadlockMikulas Patocka
__get_memory_limit() tests if dm_bufio_cache_size changed and calls __cache_size_refresh() if it did. It takes dm_bufio_clients_lock while it already holds the client lock. However, lock ordering is violated because in cleanup_old_buffers() dm_bufio_clients_lock is taken before the client lock. This results in a possible deadlock and lockdep engine warning. Fix this deadlock by changing mutex_lock() to mutex_trylock(). If the lock can't be taken, it will be re-checked next time when a new buffer is allocated. Also add "unlikely" to the if condition, so that the optimizer assumes that the condition is false.

VLAN aware Marvell chips can program 802.1Q VLAN membership as well as 802.1s per VLAN Spanning Tree state using the same 3 VTU Data registers. Some chips such as 88E6185 use different Data registers offsets for ports state and membership, and program them in a single operation. Other chips such as 88E6352 use the same register layout but program them in distinct operations (an indirect table is used for 802.1s.) Newer chips such as 88E6390 use the same offsets for both state and membership in distinct operations, thus require multiple data accesses. To correctly abstract this, split the "data" structure member of mv88e6xxx_vtu_entry in two "state" and "member" members, before adding VTU support for newer chips.

Pull block layer updates from Jens Axboe: - Add BFQ IO scheduler under the new blk-mq scheduling framework. BFQ was initially a fork of CFQ, but subsequently changed to implement fairness based on B-WF2Q+, a modified variant of WF2Q. BFQ is meant to be used on desktop type single drives, providing good fairness. From Paolo. - Add Kyber IO scheduler. This is a full multiqueue aware scheduler, using a scalable token based algorithm that throttles IO based on live completion IO stats, similary to blk-wbt. From Omar. - A series from Jan, moving users to separately allocated backing devices. This continues the work of separating backing device life times, solving various problems with hot removal. - A series of updates for lightnvm, mostly from Javier. Includes a 'pblk' target that exposes an open channel SSD as a physical block device. - A series of fixes and improvements for nbd from Josef. - A series from Omar, removing queue sharing between devices on mostly legacy drivers. This helps us clean up other bits, if we know that a queue only has a single device backing. This has been overdue for more than a decade. - Fixes for the blk-stats, and improvements to unify the stats and user windows. This both improves blk-wbt, and enables other users to register a need to receive IO stats for a device. From Omar. - blk-throttle improvements from Shaohua. This provides a scalable framework for implementing scalable priotization - particularly for blk-mq, but applicable to any type of block device. The interface is marked experimental for now. - Bucketized IO stats for IO polling from Stephen Bates.

2017-05-01mlxsw: spectrum_router: Simplify VRF enslavementIdo Schimmel
When a netdev is enslaved to a VRF master, its router interface (RIF) needs to be destroyed (if exists) and a new one created using the corresponding virtual router (VR). >From the driver's perspective, the above is equivalent to an inetaddr event sent for this netdev. Therefore, when a port netdev (or its uppers) are enslaved to a VRF master, call the same function that would've been called had a NETDEV_UP was sent for this netdev in the inetaddr notification chain. This patch also fixes a bug when a LAG netdev with an existing RIF is enslaved to a VRF. Before this patch, each LAG port would drop the reference on the RIF, but would re-join the same one (in the wrong VR) soon after. With this patch, the corresponding RIF is first destroyed and a new one is created using the correct VR.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux mlx5-updates-2017-04-30 Or says: ================ mlx5 neigh update This series (whose code name is 'neigh update') from Hadar, enhances the mlx5 TC IP tunnel offloads to deal with changes to tunnel destination neighbours used in offloaded flows which involved encapsulation. In order to keep track on the validity state of such neighbours, we register a netevent notifier callback and act on NEIGH_UPDATE events: if a neighbour becomes valid, offload the related flows to HW (the other way around when neigh becomes invalid) and similarly when a neigh mac addresses changes. Since this traffic is offloaded from the host OS, the neighbour for the IP tunnel destination can mistakenly become STALE and deleted by the kernel since its 'used' value wasn't changed. To address that, we proactively update the neighbour 'used' value every DELAY_PROBE_TIME seconds, using time stamps generated by the existing driver code for HW flow counters. We use the DELAY_PROBE_TIME_UPDATE event to adjust the frequency of the updates. Prior to the core of the series, there's a patch from Saeed that introduces an extendable vport representor implementation scheme. It provides a separation between the eswitch to the netdev related aspects of the representors. We would like to thank Ido Schimmel and Ilya Lesokhin for their coaching && advice through the long design and review cycles while we struggled to understand and (hopefully correctly) implement the locking around the different driver flows(..) . - Or. ================= Misc Updates: From Tariq: Some small performance and trivial code optimization for mlx5 netdev driver - Optimize poll ICOSQ completion queue - Use prefetchw when a write is to follow - Use u8 as ownership type in mlx5e_get_cqe() From Eran: - Disable LRO by default on specific setups From Eli: - Small cleanup for E-Switch to avoid redundant allocation Signed-off-by: David S.

2017-05-01mm, zone_device: Replace {get, put}_zone_device_page() with a single ↵Dan Williams
reference to fix pmem crash The x86 conversion to the generic GUP code included a small change which causes crashes and data corruption in the pmem code - not good. The root cause is that the /dev/pmem driver code implicitly relies on the x86 get_user_pages() implementation doing a get_page() on the page refcount, because get_page() does a get_zone_device_page() which properly refcounts pmem's separate page struct arrays that are not present in the regular page struct structures. (The pmem driver does this because it can cover huge memory areas.) But the x86 conversion to the generic GUP code changed the get_page() to page_cache_get_speculative() which is faster but doesn't do the get_zone_device_page() call the pmem code relies on. One way to solve the regression would be to change the generic GUP code to use get_page(), but that would slow things down a bit and punish other generic-GUP using architectures for an x86-ism they did not care about. (Arguably the pmem driver was probably not working reliably for them: but nvdimm is an Intel feature, so non-x86 exposure is probably still limited.) So restructure the pmem code's interface with the MM instead: get rid of the get/put_zone_device_page() distinction, integrate put_zone_device_page() into __put_page() and and restructure the pmem completion-wait and teardown machinery: Kirill points out that the calls to {get,put}_dev_pagemap() can be removed from the mm fast path if we take a single get_dev_pagemap() reference to signify that the page is alive and use the final put of the page to drop that reference. This does require some care to make sure that any waits for the percpu_ref to drop to zero occur *after* devm_memremap_page_release(), since it now maintains its own elevated reference. This speeds up things while also making the pmem refcounting more robust going forward.

This patch allows users to enable/disable internal TX and/or RX clock delay for BCM5481x series PHYs so as to satisfy RGMII timing specifications. On a particular platform, whether TX and/or RX clock delay is required depends on how PHY connected to the MAC IP.

2017-04-30bnx2x: Align RX buffersScott Wood
The bnx2x driver is not providing proper alignment on the receive buffers it passes to build_skb(), causing skb_shared_info to be misaligned. skb_shared_info contains an atomic, and while PPC normally supports unaligned accesses, it does not support unaligned atomics. Aligning the size of rx buffers will ensure that page_frag_alloc() returns aligned addresses. This can be reproduced on PPC by setting the network MTU to 1450 (or other non-multiple-of-4) and then generating sufficient inbound network traffic (one or two large "wget"s usually does it), producing the following oops: Unable to handle kernel paging request for unaligned access at address 0xc00000ffc43af656 Faulting instruction address: 0xc00000000080ef8c Oops: Kernel access of bad area, sig: 7 [#1] SMP NR_CPUS=2048 NUMA PowerNV Modules linked in: vmx_crypto powernv_rng rng_core powernv_op_panel leds_powernv led_class nfsd ip_tables x_tables autofs4 xfs lpfc bnx2x mdio libcrc32c crc_t10dif crct10dif_generic crct10dif_common CPU: 104 PID: 0 Comm: swapper/104 Not tainted 4.11.0-rc8-00088-g4c761da #2 task: c00000ffd4892400 task.stack: c00000ffd4920000 NIP: c00000000080ef8c LR: c00000000080eee8 CTR: c0000000001f8320 REGS: c00000ffffc33710 TRAP: 0600 Not tainted (4.11.0-rc8-00088-g4c761da) MSR: 9000000000009033 <SF,HV,EE,ME,IR,DR,RI,LE> CR: 24082042 XER: 00000000 CFAR: c00000000080eea0 DAR: c00000ffc43af656 DSISR: 00000000 SOFTE: 1 GPR00: c000000000907f64 c00000ffffc33990 c000000000dd3b00 c00000ffcaf22100 GPR04: c00000ffcaf22e00 0000000000000000 0000000000000000 0000000000000000 GPR08: 0000000000b80008 c00000ffc43af636 c00000ffc43af656 0000000000000000 GPR12: c0000000001f6f00 c00000000fe1a000 000000000000049f 000000000000c51f GPR16: 00000000ffffef33 0000000000000000 0000000000008a43 0000000000000001 GPR20: c00000ffc58a90c0 0000000000000000 000000000000dd86 0000000000000000 GPR24: c000007fd0ed10c0 00000000ffffffff 0000000000000158 000000000000014a GPR28: c00000ffc43af010 c00000ffc9144000 c00000ffcaf22e00 c00000ffcaf22100 NIP [c00000000080ef8c] __skb_clone+0xdc/0x140 LR [c00000000080eee8] __skb_clone+0x38/0x140 Call Trace: [c00000ffffc33990] [c00000000080fb74] skb_clone+0x74/0x110 (unreliable) [c00000ffffc339c0] [c000000000907f64] packet_rcv+0x144/0x510 [c00000ffffc33a40] [c000000000827b64] __netif_receive_skb_core+0x5b4/0xd80 [c00000ffffc33b00] [c00000000082b2bc] netif_receive_skb_internal+0x2c/0xc0 [c00000ffffc33b40] [c00000000082c49c] napi_gro_receive+0x11c/0x260 [c00000ffffc33b80] [d000000066483d68] bnx2x_poll+0xcf8/0x17b0 [bnx2x] [c00000ffffc33d00] [c00000000082babc] net_rx_action+0x31c/0x480 [c00000ffffc33e10] [c0000000000d5a44] __do_softirq+0x164/0x3d0 [c00000ffffc33f00] [c0000000000d60a8] irq_exit+0x108/0x120 [c00000ffffc33f20] [c000000000015b98] __do_irq+0x98/0x200 [c00000ffffc33f90] [c000000000027f14] call_do_irq+0x14/0x24 [c00000ffd4923a90] [c000000000015d94] do_IRQ+0x94/0x110 [c00000ffd4923ae0] [c000000000008d90] hardware_interrupt_common+0x150/0x160 Signed-off-by: David S.
