If ON or ONCE, then the follower will reply with a STATUS message. Either once or whenever the status changes (status_req == ON). If status_req == OFF, then it will stop sending continuous status updates, but the follower will *not* send a STATUS message in that case.

[ Upstream commit 89a26cd4b501e9511d3cd3d22327fc76a75a38b3 ] When running a 64-bit kernel with a 32-bit iptables binary, the size of the xt_nfacct_match_info struct diverges. kernel: sizeof(struct xt_nfacct_match_info) : 40 iptables: sizeof(struct xt_nfacct_match_info)) : 36 Trying to append nfacct related rules results in an unhelpful message.

Jonathan Looney reported that a malicious peer can force a sender to fragment its retransmit queue into tiny skbs, inflating memory usage and/or overflow 32bit counters. TCP allows an application to queue up to sk_sndbuf bytes, so we need to give some allowance for non malicious splitting of retransmit queue. A new SNMP counter is added to monitor how many times TCP did not allow to split an skb if the allowance was exceeded. Note that this counter might increase in the case applications use SO_SNDBUF socket option to lower sk_sndbuf.

2019-06-11fuse: Add FOPEN_STREAM to use stream_open()Kirill Smelkov
commit bbd84f33652f852ce5992d65db4d020aba21f882 upstream. Starting from commit 9c225f2655e3 ("vfs: atomic f_pos accesses as per POSIX") files opened even via nonseekable_open gate read and write via lock and do not allow them to be run simultaneously. This can create read vs write deadlock if a filesystem is trying to implement a socket-like file which is intended to be simultaneously used for both read and write from filesystem client. See commit 10dce8af3422 ("fs: stream_open - opener for stream-like files so that read and write can run simultaneously without deadlock") for details and e.g. commit 581d21a2d02a ("xenbus: fix deadlock on writes to /proc/xen/xenbus") for a similar deadlock example on /proc/xen/xenbus. To avoid such deadlock it was tempting to adjust fuse_finish_open to use stream_open instead of nonseekable_open on just FOPEN_NONSEEKABLE flags, but grepping through Debian codesearch shows users of FOPEN_NONSEEKABLE, and in particular GVFS which actually uses offset in its read and write handlers https://codesearch.debian.net/search?q=-%3Enonseekable+%3D https://gitlab.gnome.org/GNOME/gvfs/blob/1.40.0-6-gcbc54396/client/gvfsfusedaemon.c#L1080 https://gitlab.gnome.org/GNOME/gvfs/blob/1.40.0-6-gcbc54396/client/gvfsfusedaemon.c#L1247-1346 https://gitlab.gnome.org/GNOME/gvfs/blob/1.40.0-6-gcbc54396/client/gvfsfusedaemon.c#L1399-1481 so if we would do such a change it will break a real user. Add another flag (FOPEN_STREAM) for filesystem servers to indicate that the opened handler is having stream-like semantics; does not use file position and thus the kernel is free to issue simultaneous read and write request on opened file handle. This patch together with stream_open() should be added to stable kernels starting from v3.14+. This will allow to patch OSSPD and other FUSE filesystems that provide stream-like files to return FOPEN_STREAM | FOPEN_NONSEEKABLE in open handler and this way avoid the deadlock on all kernel versions. This should work because fuse_finish_open ignores unknown open flags returned from a filesystem and so passing FOPEN_STREAM to a kernel that is not aware of this flag cannot hurt. In turn the kernel that is not aware of FOPEN_STREAM will be < v3.14 where just FOPEN_NONSEEKABLE is sufficient to implement streams without read vs write deadlock.

2019-05-16IB/rxe: Revise the ib_wr_opcode enumJason Gunthorpe
[ Upstream commit 9a59739bd01f77db6fbe2955a4fce165f0f43568 ] 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.

[ Upstream commit 1ec17dbd90f8b638f41ee650558609c1af63dfa0 ] Field idiag_ext in struct inet_diag_req_v2 used as bitmap of requested extensions has only 8 bits. Thus extensions starting from DCTCPINFO cannot be requested directly. Some of them included into response unconditionally or hook into some of lower 8 bits. Extension INET_DIAG_CLASS_ID has not way to request from the beginning. This patch bundle it with INET_DIAG_TCLASS (ipv6 tos), fixes space reservation, and documents behavior for other extensions. Also this patch adds fallback to reporting socket priority. This filed is more widely used for traffic classification because ipv4 sockets automatically maps TOS to priority and default qdisc pfifo_fast knows about that. But priority could be changed via setsockopt SO_PRIORITY so INET_DIAG_TOS isn't enough for predicting class. Also cgroup2 obsoletes net_cls classid (it always zero), but we cannot reuse this field for reporting cgroup2 id because it is 64-bit (ino+gen). So, after this patch INET_DIAG_CLASS_ID will report socket priority for most common setup when net_cls isn't set and/or cgroup2 in use.

commit da360299b6734135a5f66d7db458dcc7801c826a upstream. This fixes a compile problem of some user space applications by not including linux/libc-compat.h in uapi/if_ether.h. linux/libc-compat.h checks which "features" the header files, included from the libc, provide to make the Linux kernel uapi header files only provide no conflicting structures and enums. If a user application mixes kernel headers and libc headers it could happen that linux/libc-compat.h gets included too early where not all other libc headers are included yet. Then the linux/libc-compat.h would not prevent all the redefinitions and we run into compile problems. This patch removes the include of linux/libc-compat.h from uapi/if_ether.h to fix the recently introduced case, but not all as this is more or less impossible. It is no problem to do the check directly in the if_ether.h file and not in libc-compat.h as this does not need any fancy glibc header detection as glibc never provided struct ethhdr and should define __UAPI_DEF_ETHHDR by them self when they will provide this. The following test program did not compile correctly any more: #include <linux/if_ether.h> #include <netinet/in.h> #include <linux/in.h> int main(void) { return 0; } Fixes: 6926e041a892 ("uapi/if_ether.h: prevent redefinition of struct ethhdr") Reported-by: Guillaume Nault <g.nault@alphalink.fr> Cc: <stable@vger.kernel.org> # 4.15 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: David S.

commit 6926e041a8920c8ec27e4e155efa760aa01551fd upstream. Musl provides its own ethhdr struct definition. Add a guard to prevent its definition of the appropriate musl header has already been included. glibc does not implement this header, but when glibc will implement this they can just define __UAPI_DEF_ETHHDR 0 to make it work with the kernel.

2019-02-12drm: content-type property for HDMI connectorStanislav Lisovskiy
Added content_type property to drm_connector_state in order to properly handle external HDMI TV content-type setting. v2: * Moved helper function which attaches content type property to the drm core, as was suggested. Removed redundant connector state initialization. v3: * Removed caps in drm_content_type_enum_list. After some discussion it turned out that HDMI Spec 1.4 was wrongly assuming that IT Content(itc) bit doesn't affect Content type states, however itc bit needs to be manupulated as well. In order to not expose additional property for itc, for sake of simplicity it was decided to bind those together in same "content type" property. v4: * Added it_content checking in intel_digital_connector_atomic_check. Fixed documentation for new content type enum. v5: * Moved patch revision's description to commit messages. v6: * Minor naming fix for the content type enumeration string. v7: * Fix parameter name for documentation and parameter alignment in order not to get warning. Added Content Type description to new HDMI connector properties section. v8: * Thrown away unneeded numbers from HDMI content-type property description. Switch to strings desription instead of plain definitions. v9: * Moved away hdmi specific content-type enum from drm_connector_state. Content type property should probably not be bound to any specific connector interface in drm_connector_state. Same probably should be done to hdmi_picture_aspect_ration enum which is also contained in drm_connector_state. Added special helper function to get derive hdmi specific relevant infoframe fields. v10: * Added usage description to HDMI properties kernel doc. v11: * Created centralized function for filling HDMI AVI infoframe, based on correspondent DRM property value.

2019-02-12drm: Add Content Protection propertySean Paul
This patch adds a new optional connector property to allow userspace to enable protection over the content it is displaying. This will typically be implemented by the driver using HDCP. The property is a tri-state with the following values: - OFF: Self explanatory, no content protection - DESIRED: Userspace requests that the driver enable protection - ENABLED: Once the driver has authenticated the link, it sets this value The driver is responsible for downgrading ENABLED to DESIRED if the link becomes unprotected. The driver should also maintain the desiredness of protection across hotplug/dpms/suspend. If this looks familiar, I posted [1] this 3 years ago. We have been using this in ChromeOS across exynos, mediatek, and rockchip over that time. Changes in v2: - Pimp kerneldoc for content_protection_property (Daniel) - Drop sysfs attribute Changes in v3: - None Changes in v4: - Changed kerneldoc to recommend userspace polling (Daniel) - Changed kerneldoc to briefly describe how to attach the property (Daniel) Changes in v5: - checkpatch whitespace noise - Change DRM_MODE_CONTENT_PROTECTION_OFF to DRM_MODE_CONTENT_PROTECTION_UNDESIRED Changes in v6: - None Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Sean Paul <seanpaul@chromium.org> [1] https://lists.freedesktop.org/archives/dri-devel/2014-December/073336.html Link: https://patchwork.freedesktop.org/patch/msgid/20180108195545.218615-4-seanpaul@chromium.org

2019-02-12tee: new ioctl to a register tee_shm from a dmabuf file descriptorEtienne Carriere
This change allows userland to create a tee_shm object that refers to a dmabuf reference. Userland provides a dmabuf file descriptor as buffer reference. The created tee_shm object exported as a brand new dmabuf reference used to provide a clean fd to userland. Userland shall closed this new fd to release the tee_shm object resources. The initial dmabuf resources are tracked independently through original dmabuf file descriptor. Once the buffer is registered and until it is released, TEE driver keeps a refcount on the registered dmabuf structure. This change only support dmabuf references that relates to physically contiguous memory buffers. New tee_shm flag to identify tee_shm objects built from a registered dmabuf: TEE_SHM_EXT_DMA_BUF. Such tee_shm structures are flagged both TEE_SHM_DMA_BUF and TEE_SHM_EXT_DMA_BUF.

2019-02-12drm: Add four ioctls for managing drm mode object leases [v7]Keith Packard
drm_mode_create_lease Creates a lease for a list of drm mode objects, returning an fd for the new drm_master and a 64-bit identifier for the lessee drm_mode_list_lesees List the identifiers of the lessees for a master file drm_mode_get_lease List the leased objects for a master file drm_mode_revoke_lease Erase the set of objects managed by a lease. This should suffice to at least create and query leases. Changes for v2 as suggested by Daniel Vetter <daniel.vetter@ffwll.ch>: * query ioctls only query the master associated with the provided file. * 'mask_lease' value has been removed * change ioctl has been removed. Changes for v3 suggested in part by Dave Airlie <airlied@gmail.com> * Add revoke ioctl. Changes for v4 suggested by Dave Airlie <airlied@gmail.com> * Expand on the comment about the magic use of &drm_lease_idr_object * Pad lease ioctl structures to align on 64-bit boundaries Changes for v5 suggested by Dave Airlie <airlied@gmail.com> * Check for non-negative object_id in create_lease to avoid debug output from the kernel. Changes for v6 provided by Dave Airlie <airlied@gmail.com> * For non-universal planes add primary/cursor planes to lease If we aren't exposing universal planes to this userspace client, and it requests a lease on a crtc, we should implicitly export the primary and cursor planes for the crtc. If the lessee doesn't request universal planes, it will just see the crtc, but if it does request them it will then see the plane objects as well. This also moves the object look ups earlier as a side effect, so we'd exit the ioctl quicker for non-existant objects. * Restrict leases to crtc/connector/planes. This only allows leasing for objects we wish to allow.
