2019-01-25cfg80211: Allow drivers to advertise supported AKM suitesVeerendranath Jakkam1-0/+6
There was no such capability advertisement from the driver and thus the current user space has to assume the driver to support all the AKMs. While that may be the case with some drivers (e.g., mac80211-based ones), there are cfg80211-based drivers that implement SME and have constraints on which AKMs can be supported (e.g., such drivers may need an update to support SAE AKM using NL80211_CMD_EXTERNAL_AUTH). Allow such drivers to advertise the exact set of supported AKMs so that user space tools can determine what network profile options should be allowed to be configured.

2019-01-25xsk: add sock_diag interface for AF_XDPBjörn Töpel1-0/+72
This patch adds the sock_diag interface for querying sockets from user space. Tools like iproute2 ss(8) can use this interface to list open AF_XDP sockets. The user-space ABI is defined in linux/xdp_diag.h and includes netlink request and response structs. The request can query sockets and the response contains socket information about the rings, umems, inode and more.

2019-01-24virtio: support VIRTIO_F_ORDER_PLATFORMTiwei Bie1-0/+6
This patch introduces the support for VIRTIO_F_ORDER_PLATFORM. If this feature is negotiated, the driver must use the barriers suitable for hardware devices. Otherwise, the device and driver are assumed to be implemented in software, that is they can be assumed to run on identical CPUs in an SMP configuration. Thus a weaker form of memory barriers is sufficient to yield better performance. It is recommended that an add-in card based PCI device offers this feature for portability. The device will fail to operate further or will operate in a slower emulation mode if this feature is offered but not accepted. Signed-off-by: Tiwei Bie <[email protected]> Signed-off-by: Michael S.

2019-01-22bridge: Snoop Multicast Router AdvertisementsLinus Lüssing2-0/+3
When multiple multicast routers are present in a broadcast domain then only one of them will be detectable via IGMP/MLD query snooping. The multicast router with the lowest IP address will become the selected and active querier while all other multicast routers will then refrain from sending queries. To detect such rather silent multicast routers, too, RFC4286 ("Multicast Router Discovery") provides a standardized protocol to detect multicast routers for multicast snooping switches. This patch implements the necessary MRD Advertisement message parsing and after successful processing adds such routers to the internal multicast router list.

2019-01-22bridge: join all-snoopers multicast addressLinus Lüssing1-4/+5
Next to snooping IGMP/MLD queries RFC4541, section 2.1.1.a) recommends to snoop multicast router advertisements to detect multicast routers. Multicast router advertisements are sent to an "all-snoopers" multicast address. To be able to receive them reliably, we need to join this group. Otherwise other snooping switches might refrain from forwarding these advertisements to us. Signed-off-by: Linus Lüssing <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2019-01-22bonding: add support for xstats and export 3ad statsNikolay Aleksandrov2-0/+25
This patch adds support for extended statistics (xstats) call to the bonding. The first user would be the 3ad code which counts the following events: - LACPDU Rx/Tx - LACPDU unknown type Rx - LACPDU illegal Rx - Marker Rx/Tx - Marker response Rx/Tx - Marker unknown type Rx All of these are exported via netlink as separate attributes to be easily extensible as we plan to add more in the future. Similar to how the bridge and other xstats exports, the structure inside is: [ IFLA_STATS_LINK_XSTATS ] -> [ LINK_XSTATS_TYPE_BOND ] -> [ BOND_XSTATS_3AD ] -> [ 3ad stats attributes ] With this structure it's easy to add more stat types later.

2019-01-21perf, bpf: Introduce PERF_RECORD_BPF_EVENTSong Liu1-1/+28
For better performance analysis of BPF programs, this patch introduces PERF_RECORD_BPF_EVENT, a new perf_event_type that exposes BPF program load/unload information to user space. Each BPF program may contain up to BPF_MAX_SUBPROGS (256) sub programs. The following example shows kernel symbols for a BPF program with 7 sub programs: ffffffffa0257cf9 t bpf_prog_b07ccb89267cf242_F ffffffffa02592e1 t bpf_prog_2dcecc18072623fc_F ffffffffa025b0e9 t bpf_prog_bb7a405ebaec5d5c_F ffffffffa025dd2c t bpf_prog_a7540d4a39ec1fc7_F ffffffffa025fcca t bpf_prog_05762d4ade0e3737_F ffffffffa026108f t bpf_prog_db4bd11e35df90d4_F ffffffffa0263f00 t bpf_prog_89d64e4abf0f0126_F ffffffffa0257cf9 t bpf_prog_ae31629322c4b018__dummy_tracepoi When a bpf program is loaded, PERF_RECORD_KSYMBOL is generated for each of these sub programs. Therefore, PERF_RECORD_BPF_EVENT is not needed for simple profiling. For annotation, user space need to listen to PERF_RECORD_BPF_EVENT and gather more information about these (sub) programs via sys_bpf.

Devlink health buffer is a mechanism to pass descriptors between drivers and devlink. The API allows the driver to add objects, object pair, value array (nested attributes), value and name. Driver can use this API to fill the buffers in a format which can be translated by the devlink to the netlink message. In order to fulfill it, an internal buffer descriptor is defined. This will hold the data and metadata per each attribute and by used to pass actual commands to the netlink.

Sync with mainline to get linux/overflow.h among other things.
2019-01-13Input: input_event - provide override for sparc64Deepa Dinamani1-1/+5
The usec part of the timeval is defined as __kernel_suseconds_t tv_usec; /* microseconds */ Arnd noticed that sparc64 is the only architecture that defines __kernel_suseconds_t as int rather than long. This breaks the current y2038 fix for kernel as we only access and define the timeval struct for non-kernel use cases. But, this was hidden by an another typo in the use of __KERNEL__ qualifier. Fix the typo, and provide an override for sparc64.

2019-01-07media: videodev2.h: add v4l2_timeval_to_ns inline functionHans Verkuil1-0/+12
We want to be able to uniquely identify buffers for stateless codecs. The internal timestamp (a u64) as stored internally in the kernel is a suitable candidate for that, but in struct v4l2_buffer it is represented as a struct timeval. Add a v4l2_timeval_to_ns() function that converts the struct timeval into a u64 in the same way that the kernel does. This makes it possible to use this u64 elsewhere as a unique identifier of the buffer. Since timestamps are also copied from the output buffer to the corresponding capture buffer(s) by M2M devices, the u64 can be used to refer to both output and capture buffers. The plan is that in the future we redesign struct v4l2_buffer and use u64 for the timestamp instead of a struct timeval (which has lots of problems with 32 vs 64 bit and y2038 layout changes), and then there is no more need to use this function.

2019-01-07Fix a handful of audit-related issuePalmer Dabbelt1-0/+2
This is sort of a mix between a new feature and a bug fix. I've managed to screw up merging this patch set a handful of times but I think it's OK this time around. The main new feature here is audit support for RISC-V, with some fixes to audit-related bugs that cropped up along the way: * The addition of NR_syscalls into unistd.h, which is necessary for CONFIG_FTRACE_SYSCALLS. * The definition of CREATE_TRACE_POINTS so __tracepoint_sys_{enter,exit} get defined. * A fix for trace_sys_exit() so we can enable CONFIG_HAVE_SYSCALL_TRACEPOINTS.

2019-01-06fscrypt: add Adiantum supportEric Biggers1-1/+3
Add support for the Adiantum encryption mode to fscrypt. Adiantum is a tweakable, length-preserving encryption mode with security provably reducible to that of XChaCha12 and AES-256, subject to a security bound. It's also a true wide-block mode, unlike XTS. See the paper "Adiantum: length-preserving encryption for entry-level processors" (https://eprint.iacr.org/2018/720.pdf) for more details. Also see commit 059c2a4d8e16 ("crypto: adiantum - add Adiantum support"). On sufficiently long messages, Adiantum's bottlenecks are XChaCha12 and the NH hash function. These algorithms are fast even on processors without dedicated crypto instructions. Adiantum makes it feasible to enable storage encryption on low-end mobile devices that lack AES instructions; currently such devices are unencrypted. On ARM Cortex-A7, on 4096-byte messages Adiantum encryption is about 4 times faster than AES-256-XTS encryption; decryption is about 5 times faster. In fscrypt, Adiantum is suitable for encrypting both file contents and names. With filenames, it fixes a known weakness: when two filenames in a directory share a common prefix of >= 16 bytes, with CTS-CBC their encrypted filenames share a common prefix too, leaking information. Adiantum does not have this problem. Since Adiantum also accepts long tweaks (IVs), it's also safe to use the master key directly for Adiantum encryption rather than deriving per-file keys, provided that the per-file nonce is included in the IVs and the master key isn't used for any other encryption mode. This configuration saves memory and improves performance. A new fscrypt policy flag is added to allow users to opt-in to this configuration.
