Merge tag 'wireless-drivers-next-for-davem-2015-10-27' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== here's a bigger pull request for 4.4. The diffstat looks scary as we created a new directory realtek for all realtek drivers. In the future I'm planning to create similar directories for all vendors, currently we just have ath, mediatek and realtek. This change has been in linux-next for a couple of weeks so it should be safe, but of course you never know. There's also a new driver rtl8xxxu for few realtek USB devices. This just made it to the last linux-next build. Otherwise there's nothing really special, more info below. If time permits, and it's ok for you, I'm hoping to send you a one more pull request this week. brcmfmac * using netdev carrier state * add and rework some cfg80211 callbacks mainly for AP mode * use devcoredump when triggered by firmware event realtek * create new directory drivers/net/wireless/realtek/ for all realtek drivers, not visible to users (no kconfig changes etc) * add rtl8xxxu, a new mac80211 driver for RTL8723AU, RTL8188CU, RTL8188RU, RTL8191CU, RTL8192CU and hopefully more in the future ath10k * add board 2 API support for automatically choosing correct board file * data path optimisations * disable PCI power save for qca988x and QCA99x0 due to interop reasons wil6210 * BlockAckReq support * firmware crashdump using devcoredump * capture all frames with sniffer ==================== Signed-off-by:

This patch adds support for dumping a process' (classic BPF) seccomp filters via ptrace. PTRACE_SECCOMP_GET_FILTER allows the tracer to dump the user's classic BPF seccomp filters. addr should be an integer which represents the ith seccomp filter (0 is the most recently installed filter). data should be a struct sock_filter * with enough room for the ith filter, or NULL, in which case the filter is not saved. The return value for this command is the number of BPF instructions the program represents, or negative in the case of errors. Command specific errors are ENOENT: which indicates that there is no ith filter in this seccomp tree, and EMEDIUMTYPE, which indicates that the ith filter was not installed as a classic BPF filter. A caveat with this approach is that there is no way to get explicitly at the heirarchy of seccomp filters, and users need to memcmp() filters to decide which are inherited. This means that a task which installs two of the same filter can potentially confuse users of this interface. v2: * make save_orig const * check that the orig_prog exists (not necessary right now, but when grows eBPF support it will be) * s/n/filter_off and make it an unsigned long to match ptrace * count "down" the tree instead of "up" when passing a filter offset v3: * don't take the current task's lock for inspecting its seccomp mode * use a 0x42** constant for the ptrace command value v4: * don't copy to userspace while holding spinlocks v5: * add another condition to WARN_ON v6: * rebase on net-next Signed-off-by:Tycho Andersen <tycho.andersen@canonical.com> Acked-by:

Robert Shearman says: ==================== mpls: mulipath improvements Two improvements to the recently added mpls multipath support. The first is a fix for missing initialisation the nexthop address length for the v4 and v6 explicit null label routes, and the second is to reduce the amount of memory used by mpls routes by changing the way the via addresses are stored. ==================== Signed-off-by: -
Robert Shearman authored
Nexthops for MPLS routes have a via address field sized for the largest via address that is expected, which is 32 bytes. This means that in the most common case of having ipv4 via addresses, 28 bytes of memory more than required are used per nexthop. In the other common case of an ipv6 nexthop then 16 bytes more than required are used. With large numbers of MPLS routes this extra memory usage could start to become significant. To avoid allocating memory for a maximum length via address when not all of it is required and to allow for ease of iterating over nexthops, then the via addresses are changed to be stored in the same memory block as the route and nexthops, but in an array after the end of the array of nexthops. New accessors are provided to retrieve a pointer to the via address. To allow for O(1) access without having to store a pointer or offset per nh, the via address for each nexthop is sized according to the maximum via address for any nexthop in the route, which is stored in a new route field, rt_max_alen, but this is in an existing hole in struct mpls_route so it doesn't increase the size of the structure. Each via address is ensured to be aligned to VIA_ALEN_ALIGN to account for architectures that don't allow unaligned accesses. Signed-off-by:

netstamp_needed is toggled for all socket families if they request timestamping. But some protocols don't need the lower-layer timestamping code at all. This patch starts disabling it for af-unix. E.g. systemd enables timestamping during boot-up on the journald af-unix sockets, thus causing the system to globally enable timestamping in the lower networking stack. Still, it is very probable that timestamping gets activated, by e.g. dhclient or various NTP implementations. Reported-by:

Ariel Elior says: ==================== Add new drivers: qed & qede This series implements the driver set for Qlogic's new QL4xxx series. These are 10/20/25/40/50/100 Gig capable converged nics, supporting ethernet (obviously), iscsi, fcoe, roce and iwarp protocols. The overall driver design includes a common module ('qed') and protocol specific dependent modules for ethernet ('qede'), fcoe ('qedf'), iscsi ('qedi') and roce ('qedr'). The common module contains all of the common logic, e.g. initialization, cleanup, infrastructure for interrupt handling, link management, slowpath etc. as well as protocol agnostic features, and supplying an abstraction layer for other modules. The protocol specific modules can be compiled and operated independently of each other, with the exception of the rdma modules which are dependent on the ethernet module, in accordance with the kernel rdma stack design. This series only adds the core and ethernet modules, with basic L2 capabilities. Future series will add the rest of the modules and enhance the L2 functionality. Ths patch series is constructed of the following patches: qed: Add module with basic common support qed: Add basic L2 interface qede: Add basic Network driver qed: Add slowpath L2 support qede: Add basic network device support qede: Add classification configuration qed: Add link support qede: Add support for link qed: Add statistics support qede: Add basic ethtool support This project is a team effort, thanks go to Yuval Mintz, Dmitry Kravkov, Michal Kalderon, Tomer Tayar, Manish Chopra, Sudarsana Kalluru, Rajesh Borundia, Sony Chacko, Artum Zolotushko, Harish Patil, Rasesh Mody, Sergey Ukhterov and Elad Manela, as well as former team members, Eilon Greenstein and Shmulik Ravid. Changes from previos version: ----------------------------- From Version 7: - Various small fixes according to Dave's suggestions; Largest change [code-wise] - don't use tabs for indenting function arguments. From Version 6: - Reduced the number of arguments for functions with exceptionally high number of parameters. From Version 5: - Style change and fixes [mostly in 1, 4 and 7]. Thanks go to Francois Romieu, a mere mortal. ;-) From Version 4: - Drop dependency for x86_64. From Version 3: - Limit support of initial submission to x86_64. - Fix endian problems appearing via sparse [although no BE support yet]. - Fix small issues suggested by the kbuild test robot. From Version 2: - Removed U64_{HI,LO}; Using {upper,lower}_32_bits instead. - Use regular napi weight definition. - [We still use the __le variants for variables, since we didn't get a reply regarding the change into non-user API types]. From Version 1: - Removed private license file; Instead revised comments at source headers. ==================== Signed-off-by: -

This adds basic link functionality to qede - driver still doesn't provide users with an API to change any link property, but it does request qed to initialize the link using default configuration, and registers a callback that allows it to get link notifications. This patch adds the ability of the driver to set the carrier as active and to enable traffic as a result of async. link notifications. Following this patch, driver should be capable of running traffic. Signed-off-by:

Yuval Mintz authored
Physical link is handled by the management Firmware. This patch lays the infrastructure for attention handling in the driver, as link change notifications arrive via async. attentions, as well the handling of such notifications. This patch also extends the API with the protocol drivers by adding registered callbacks which the protocol driver passes to qed in order to be notified of async. events originating from the FW/HW.

This patch adds a public API for a network driver to work on top of QED. The interface itself is very minimal - it's mostly infrastructure, as the only content it has after this patch is a query for HW-based information required for the creation of a network interface [I.e., no actual protocol-specific configurations are supported].

Yuval Mintz authored
The Qlogic Everest Driver is the backend module for the QL4xxx ethernet products by Qlogic. This module serves two main purposes: 1. It's responsible to contain all the common code that will be shared between the various drivers that would be used with said line of products. Flows such as chip initialization and de-initialization fall under this category. 2. It would abstract the protocol-specific HW & FW components, allowing the protocol drivers to have a clean APIs which is detached in its slowpath configuration from the actual HSI. This adds a very basic module without any protocol-specific bits. I.e., this adds a basic implementation that almost entirely falls under the first category. Signed-off-by:

While the current driver mostly supports BCM7445 which has a hardcoded location for its MoCA port on port 7 and port 0 for its internal PHY, this is not necessarily true for all other chips out there such as BCM3390 for instance. Walk the list of ports from Device Tree, get their port number ("reg" property), and then parse the "phy-mode" property and initialize two internal variables: moca_port and a bitmask of internal PHYs. Since we use interrupts for the MoCA port, we introduce two helper functions to enable/disable interrupts and do this at the appropriate bank (INTRL2_0 or INTRL2_1).

This short series adds ethtool statistics reporting to mvneta. Having discussed with Andrew on IRC, we decided I'd pick up his patch into my series.
