2017-02-13[media] videodev2.h: go back to limited range Y'CbCr for SRGB and, ADOBERGBHans Verkuil1-6/+17
This reverts 'commit 7e0739cd9c40 ("[media] videodev2.h: fix sYCC/AdobeYCC default quantization range"). The problem is that many drivers can convert R'G'B' content (often from sensors) to Y'CbCr, but they all produce limited range Y'CbCr. To stay backwards compatible the default quantization range for sRGB and AdobeRGB Y'CbCr encoding should be limited range, not full range, even though the corresponding standards specify full range. Update the V4L2_MAP_QUANTIZATION_DEFAULT define accordingly and also update the documentation.

2016-12-13mm: make transparent hugepage size publicHugh Dickins1-0/+5
Test programs want to know the size of a transparent hugepage. While it is commonly the same as the size of a hugetlbfs page (shown as Hugepagesize in /proc/meminfo), that is not always so: powerpc implements transparent hugepages in a different way from hugetlbfs pages, so it's coincidence when their sizes are the same; and x86 and others can support more than one hugetlbfs page size. Add /sys/kernel/mm/transparent_hugepage/hpage_pmd_size to show the THP size in bytes - it's the same for Anonymous and Shmem hugepages. Call it hpage_pmd_size (after HPAGE_PMD_SIZE) rather than hpage_size, in case some transparent support for pud and pgd pages is added later.

2016-12-13mm: remove x86-only restriction of movable_nodeReza Arbab1-1/+1
In commit c5320926e370 ("mem-hotplug: introduce movable_node boot option"), the memblock allocation direction is changed to bottom-up and then back to top-down like this: 1. memblock_set_bottom_up(true), called by cmdline_parse_movable_node(). 2. memblock_set_bottom_up(false), called by x86's numa_init(). Even though (1) occurs in generic mm code, it is wrapped by #ifdef CONFIG_MOVABLE_NODE, which depends on X86_64. This means that when we extend CONFIG_MOVABLE_NODE to non-x86 arches, things will be unbalanced. (1) will happen for them, but (2) will not. This toggle was added in the first place because x86 has a delay between adding memblocks and marking them as hotpluggable. Since other arches do this marking either immediately or not at all, they do not require the bottom-up toggle. So, resolve things by moving (1) from cmdline_parse_movable_node() to x86's setup_arch(), immediately after the movable_node parameter has been parsed.

2016-12-08net: smmac: allow configuring lower pbl valuesNiklas Cassel2-1/+6
The driver currently always sets the PBLx8/PBLx4 bit, which means that the pbl values configured via the pbl/txpbl/rxpbl DT properties are always multiplied by 8/4 in the hardware. In order to allow the DT to configure lower pbl values, while at the same time not changing behavior of any existing device trees using the pbl/txpbl/rxpbl settings, add a property to disable the multiplication of the pbl by 8/4 in the hardware.

2016-12-08net: stmmac: add support for independent DMA pbl for tx/rxNiklas Cassel2-7/+18
GMAC and newer supports independent programmable burst lengths for DMA tx/rx. Add new optional devicetree properties representing this. To be backwards compatible, snps,pbl will still be valid, but snps,txpbl/snps,rxpbl will override the value in snps,pbl if set. If the IP is synthesized to use the AXI interface, there is a register and a matching DT property inside the optional stmmac-axi-config DT node for controlling burst lengths, named snps,blen. However, using this register, it is not possible to control tx and rx independently. Also, this register is not available if the IP was synthesized with, e.g., the AHB interface.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains a large Netfilter update for net-next, to summarise: 1) Add support for stateful objects. This series provides a nf_tables native alternative to the extended accounting infrastructure for nf_tables. Two initial stateful objects are supported: counters and quotas. Objects are identified by a user-defined name, you can fetch and reset them anytime. You can also use a maps to allow fast lookups using any arbitrary key combination. More info at: http://marc.info/?l=netfilter-devel&m=148029128323837&w=2 2) On-demand registration of nf_conntrack and defrag hooks per netns. Register nf_conntrack hooks if we have a stateful ruleset, ie. state-based filtering or NAT. The new nf_conntrack_default_on sysctl enables this from newly created netnamespaces. Default behaviour is not modified. Patches from Florian Westphal. 3) Allocate 4k chunks and then use these for x_tables counter allocation requests, this improves ruleset load time and also datapath ruleset evaluation, patches from Florian Westphal. 4) Add support for ebpf to the existing x_tables bpf extension. From Willem de Bruijn. 5) Update layer 4 checksum if any of the pseudoheader fields is updated. This provides a limited form of 1:1 stateless NAT that make sense in specific scenario, eg. load balancing. 6) Add support to flush sets in nf_tables. This series comes with a new set->ops->deactivate_one() indirection given that we have to walk over the list of set elements, then deactivate them one by one. The existing set->ops->deactivate() performs an element lookup that we don't need. 7) Two patches to avoid cloning packets, thus speed up packet forwarding via nft_fwd from ingress. From Florian Westphal. 8) Two IPVS patches via Simon Horman: Decrement ttl in all modes to prevent infinite loops, patch from Dwip Banerjee. And one minor refactoring from Gao feng. 9) Revisit recent log support for nf_tables netdev families: One patch to ensure that we correctly handle non-ethernet packets. Another patch to add missing logger definition for netdev. Patches from Liping Zhang. 10) Three patches for nft_fib, one to address insufficient register initialization and another to solve incorrect (although harmless) byteswap operation. Moreover update xt_rpfilter and nft_fib to match lbcast packets with zeronet as source, eg. DHCP Discover packets (0.0.0.0 -> 255.255.255.255). Also from Liping Zhang. 11) Built-in DCCP, SCTP and UDPlite conntrack and NAT support, from Davide Caratti. While DCCP is rather hopeless lately, and UDPlite has been broken in many-cast mode for some little time, let's give them a chance by placing them at the same level as other existing protocols. Thus, users don't explicitly have to modprobe support for this and NAT rules work for them. Some people point to the lack of support in SOHO Linux-based routers that make deployment of new protocols harder. I guess other middleboxes outthere on the Internet are also to blame. Anyway, let's see if this has any impact in the midrun. 12) Skip software SCTP software checksum calculation if the NIC comes with SCTP checksum offload support. From Davide Caratti. 13) Initial core factoring to prepare conversion to hook array. Three patches from Aaron Conole. 14) Gao Feng made a wrong conversion to switch in the xt_multiport extension in a patch coming in the previous batch. Fix it in this batch. 15) Get vmalloc call in sync with kmalloc flags to avoid a warning and likely OOM killer intervention from x_tables. From Marcelo Ricardo Leitner. 16) Update Arturo Borrero's email address in all source code headers. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Hence, calc mult and shift basing on CPTS rfclk frequency if both cpts_clock_shift and cpts_clock_mult properties are not provided in DT (the basis of calculation algorithm is borrowed from __clocksource_update_freq_scale() commit 7d2f944a2b83 ("clocksource: Provide a generic mult/shift factor calculation")).

2016-12-04netfilter: conntrack: add nf_conntrack_default_on sysctlFlorian Westphal1-0/+11
This switch (default on) can be used to disable automatic registration of connection tracking functionality in newly created network namespaces. This means that when net namespace goes down (or the tracker protocol module is unloaded) we *might* have to unregister the hooks. We can either add another per-netns variable that tells if the hooks got registered by default, or, alternatively, just call the protocol _put() function and have the callee deal with a possible 'extra' put() operation that doesn't pair with a get() one. This uses the latter approach, i.e. a put() without a get has no effect. Conntrack is still enabled automatically regardless of the new sysctl setting if the new net namespace requires connection tracking, e.g. when NAT rules are created.

RFC7527 solves this by including a random nonce in the NS messages used for DAD, and if an NS is received with the same nonce it is assumed to be a looped back DAD probe and is ignored.

Couple conflicts resolved here: 1) In the MACB driver, a bug fix to properly initialize the RX tail pointer properly overlapped with some changes to support variable sized rings. 2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix overlapping with a reorganization of the driver to support ACPI, OF, as well as PCI variants of the chip. 3) In 'net' we had several probe error path bug fixes to the stmmac driver, meanwhile a lot of this code was cleaned up and reorganized in 'net-next'. 4) The cls_flower classifier obtained a helper function in 'net-next' called __fl_delete() and this overlapped with Daniel Borkamann's bug fix to use RCU for object destruction in 'net'. It also overlapped with Jiri's change to guard the rhashtable_remove_fast() call with a check against tc_skip_sw(). 5) In mlx4, a revert bug fix in 'net' overlapped with some unrelated changes in 'net-next'. 6) In geneve, a stale header pointer after pskb_expand_head() bug fix in 'net' overlapped with a large reorganization of the same code in 'net-next'. Since the 'net-next' code no longer had the bug in question, there was nothing to do other than to simply take the 'net-next' hunks. Signed-off-by: David S. Miller <davem@davemloft.net>
2016-12-02net: mvneta: Add network support for Armada 3700 SoCMarcin Wojtas1-2/+5
Armada 3700 is a new ARMv8 SoC from Marvell using same network controller as older Armada 370/38x/XP. There are however some differences that needed taking into account when adding support for it: * open default MBUS window to 4GB of DRAM - Armada 3700 SoC's Mbus configuration for network controller has to be done on two levels: global and per-port. The first one is inherited from the bootloader. The latter can be opened in a default way, leaving arbitration to the bus controller. Hence filled mbus_dram_target_info structure is not needed * make per-CPU operation optional - Recent patches adding RSS and XPS support for Armada 38x/XP enabled per-CPU operation of the controller by default. Contrary to older SoC's Armada 3700 SoC's network controller is not capable of per-CPU processing due to interrupt lines' connectivity. This patch restores non-per-CPU operation, which is now optional and depends on neta_armada3700 flag value in mvneta_port structure. In order not to complicate the code, separate interrupt subroutine is implemented. For now, on the Armada 3700, RSS is disabled as the current implementation depend on the per cpu interrupts.
