2016-12-08dm crypt: add ability to use keys from the kernel key retention serviceOndrej Kozina
The kernel key service is a generic way to store keys for the use of other subsystems. Currently there is no way to use kernel keys in dm-crypt. This patch aims to fix that. Instead of key userspace may pass a key description with preceding ':'. So message that constructs encryption mapping now looks like this: <cipher> [<key>|:<key_string>] <iv_offset> <dev_path> <start> [<#opt_params> <opt_params>] where <key_string> is in format: <key_size>:<key_type>:<key_description> Currently we only support two elementary key types: 'user' and 'logon'. Keys may be loaded in dm-crypt either via <key_string> or using classical method and pass the key in hex representation directly. dm-crypt device initialised with a key passed in hex representation may be replaced with key passed in key_string format and vice versa.

2016-12-08net: smmac: allow configuring lower pbl valuesNiklas Cassel
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 Cassel
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>

2016-12-06PM / OPP: Reword binding supporting multiple regulators per deviceViresh Kumar
On certain platforms (like TI), DVFS for a single device (CPU) requires configuring multiple power supplies. The OPP bindings already contains binding and example to explain this case, but it isn't sufficient. - There is no way for the code parsing these bindings to know which voltage values belong to which power supply. - It is not possible to know the order in which the supplies need to be configured while switching OPPs. This patch clarifies on those details by mentioning that such information is left for the implementation specific bindings to explain. They may want to hardcode such details or implement their own properties to get such information. All implementations using multiple regulators for their devices must provide a binding document explaining their implementation.
