2018-09-20usb: usbtmc: Add ioctl USBTMC_IOCTL_WRITE_RESULTGuido Kiener1-0/+1
ioctl USBTMC_IOCTL_WRITE_RESULT copies current out_transfer_size to given __u32 pointer and returns current out_status of the last (asnynchronous) USBTMC_IOCTL_WRITE call.

2018-09-20usb: usbtmc: Add ioctl for vendor specific writeGuido Kiener1-0/+14
The new ioctl USBTMC_IOCTL_WRITE sends a generic message to bulk OUT. This ioctl is used for vendor specific or asynchronous I/O as well. The message is split into chunks of 4k (page size). Message size is aligned to 32 bit boundaries. With flag USBTMC_FLAG_ASYNC the ioctl is non blocking. With flag USBTMC_FLAG_APPEND additional urbs are queued and out_status/out_transfer_size is not reset. EPOLLOUT | EPOLLWRNORM is signaled when all submitted urbs are completed. Flush flying urbs when file handle is closed or device is suspended or reset. This ioctl does not support compatibility for 32 bit applications running on 64 bit systems. However all other convenient ioctls of the USBTMC driver can still be used in 32 bit applications as well. Note that 32 bit applications running on 32 bit target systems are not affected by this limitation.

2018-09-20KVM: x86: Control guest reads of MSR_PLATFORM_INFODrew Schmitt1-0/+1
Add KVM_CAP_MSR_PLATFORM_INFO so that userspace can disable guest access to reads of MSR_PLATFORM_INFO. Disabling access to reads of this MSR gives userspace the control to "expose" this platform-dependent information to guests in a clear way. As it exists today, guests that read this MSR would get unpopulated information if userspace hadn't already set it (and prior to this patch series, only the CPUID faulting information could have been populated). This existing interface could be confusing if guests don't handle the potential for incorrect/incomplete information gracefully (e.g. zero reported for base frequency).

2018-09-17IB/rxe: Revise the ib_wr_opcode enumJason Gunthorpe1-1/+19
This enum has become part of the uABI, as both RXE and the ib_uverbs_post_send() command expect userspace to supply values from this enum. So it should be properly placed in include/uapi/rdma. In userspace this enum is called 'enum ibv_wr_opcode' as part of libibverbs.h. That enum defines different values for IB_WR_LOCAL_INV, IB_WR_SEND_WITH_INV, and IB_WR_LSO. These were introduced (incorrectly, it turns out) into libiberbs in 2015. The kernel has changed its mind on the numbering for several of the IB_WC values over the years, but has remained stable on IB_WR_LOCAL_INV and below. Based on this we can conclude that there is no real user space user of the values beyond IB_WR_ATOMIC_FETCH_AND_ADD, as they have never worked via rdma-core. This is confirmed by inspection, only rxe uses the kernel enum and implements the latter operations. rxe has clearly never worked with these attributes from userspace. Other drivers that support these opcodes implement the functionality without calling out to the kernel. To make IB_WR_SEND_WITH_INV and related work for RXE in userspace we choose to renumber the IB_WR enum in the kernel to match the uABI that userspace has bee using since before Soft RoCE was merged. This is an overall simpler configuration for the whole software stack, and obviously can't break anything existing.

2018-09-13ipv6: Add sockopt IPV6_MULTICAST_ALL analogue to IP_MULTICAST_ALLAndre Naujoks1-0/+1
The socket option will be enabled by default to ensure current behaviour is not changed. This is the same for the IPv4 version. A socket bound to in6addr_any and a specific port will receive all traffic on that port. Analogue to IP_MULTICAST_ALL, disable this behaviour, if one or more multicast groups were joined (using said socket) and only pass on multicast traffic from groups, which were explicitly joined via this socket. Without this option disabled a socket (system even) joined to multiple multicast groups is very hard to get right. Filtering by destination address has to take place in user space to avoid receiving multicast traffic from other multicast groups, which might have traffic on the same port. The extension of the IP_MULTICAST_ALL socketoption to just apply to ipv6, too, is not done to avoid changing the behaviour of current applications.

Only IB_FLOW_ATTR_FLAGS_EGRESS is supported. 2) Remove the requirement to have a DEVX or QP destination when creating a flow.

2018-09-05packet: add sockopt to ignore outgoing packetsVincent Whitchurch1-0/+1
Currently, the only way to ignore outgoing packets on a packet socket is via the BPF filter. With MSG_ZEROCOPY, packets that are looped into AF_PACKET are copied in dev_queue_xmit_nit(), and this copy happens even if the filter run from packet_rcv() would reject them. So the presence of a packet socket on the interface takes away the benefits of MSG_ZEROCOPY, even if the packet socket is not interested in outgoing packets. (Even when MSG_ZEROCOPY is not used, the skb is unnecessarily cloned, but the cost for that is much lower.) Add a socket option to allow AF_PACKET sockets to ignore outgoing packets to solve this. Note that the *BSDs already have something similar: BIOCSSEESENT/BIOCSDIRECTION and BIOCSDIRFILT. The first intended user is lldpd.

2018-09-05nl80211: Add CAN_REPLACE_PTK0 APIAlexander Wetzel1-0/+6
Drivers able to correctly replace a in-use key should set @NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 to allow the user space (e.g. hostapd or wpa_supplicant) to rekey PTK keys. The user space must detect a PTK rekey attempt and only go ahead with it when the driver has set this flag. If the driver is not supporting the feature the user space either must not replace the PTK key or perform a full re-association instead. Ignoring this flag and continuing to rekey the connection can still work but has to be considered insecure and broken. Depending on the driver it can leak clear text packets or freeze the connection and is only supported to allow the user space to be updated.

2018-09-04uapi/linux/keyctl.h: don't use C++ reserved keyword as a struct member nameRandy Dunlap1-1/+1
Since this header is in "include/uapi/linux/", apparently people want to use it in userspace programs -- even in C++ ones. However, the header uses a C++ reserved keyword ("private"), so change that to "dh_private" instead to allow the header file to be used in C++ userspace.

2018-09-04crypto: speck - remove SpeckJason A. Donenfeld1-2/+2
These are unused, undesired, and have never actually been used by anybody. The original authors of this code have changed their mind about its inclusion. While originally proposed for disk encryption on low-end devices, the idea was discarded [1] in favor of something else before that could really get going. Therefore, this patch removes Speck.

2018-09-03fanotify: add API to attach/detach super block markAmir Goldstein1-4/+12
Add another mark type flag FAN_MARK_FILESYSTEM for add/remove/flush of super block mark type. A super block watch gets all events on the filesystem, regardless of the mount from which the mark was added, unless an ignore mask exists on either the inode or the mount where the event was generated. Only one of FAN_MARK_MOUNT and FAN_MARK_FILESYSTEM mark type flags may be provided to fanotify_mark() or no mark type flag for inode mark.

A driver to let userspace turn memfd regions into dma-bufs. Use case: Allows qemu create dmabufs for the vga framebuffer or virtio-gpu ressources. Then they can be passed around to display those guest things on the host. To spice client for classic full framebuffer display, and hopefully some day to wayland server for seamless guest window display. qemu test branch: https://git.kraxel.org/cgit/qemu/log/?h=sirius/udmabuf Cc: David Airlie <[email protected]> Cc: Tomeu Vizoso <[email protected]> Cc: Laurent Pinchart <[email protected]> Cc: Daniel Vetter <[email protected]> Signed-off-by: Gerd Hoffmann <[email protected]> Acked-by: Daniel Vetter <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected]

2018-09-02net/sched: fix type of htb statisticsFlorent Fourcot1-3/+3
tokens and ctokens are defined as s64 in htb_class structure, and clamped to 32bits value during netlink dumps: cl->xstats.tokens = clamp_t(s64, PSCHED_NS2TICKS(cl->tokens), INT_MIN, INT_MAX); Defining it as u32 is working since userspace (tc) is printing it as signed int, but a correct definition from the beginning is probably better. In the same time, 'giants' structure member is unused since years, so update the comment to mark it unused. Signed-off-by: Florent Fourcot <[email protected]> Signed-off-by: David S.
