2017-12-08drm/armada: extract register generation from armada_drm_primary_set()Russell King
Extract the register generation from armada_drm_primary_set(), so that it can be re-used. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: wait for previous work when moving overlay windowRussell King
We must wait for the previous plane work to complete before moving the overlay window, as it could overwrite our positioning update. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: move overlay plane register update generationRussell King
Move the overlay plane register update generation to a separate function as this is independent of the legacy or atomic update. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: re-organise overlay register update generationRussell King
Re-organise overlay register generation so that we do not have to wait for the previous update to complete while creating the new state. This allows the update to be fully prepared before queueing it for the next interrupt. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: disable planes at next blanking periodRussell King
Disable planes at the next blanking period rather than immediately. In order to achieve this, we need to delay the clearing of dcrtc->plane until after the next blanking period, so move that into a separate work function. To avoid races, we also need to move its assignment in the overlay code. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: avoid work allocationRussell King
Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: allow armada_drm_plane_work_queue() to silently failRussell King
Avoid printing an error message when armada_drm_plane_work_queue() is unable to get the vblank (eg, because we're doing a modeset.) Continue to report the failure to the caller, so the caller can handle this. Move the error message into armada_ovl_plane_update(). Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: use drm_plane_helper_check_state()Russell King
Use drm_plane_helper_check_state() to check the overlay plane state rather than drm_plane_helper_check_update(), as: (1) using drm_plane_helper_check_state() provides a better migration path to atomic modeset (2) it avoids needless copies of drm rectangle structures, and so is more efficient. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: only enable HSMOOTH if scaling horizontallyRussell King
Only enable the HSMOOTH control bit if we are scaling horizontally, otherwise it makes no sense to enable the horizontal scaler. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: move writes of LCD_SPU_SRAM_PARA1 under lockRussell King
Move writes of LCD_SPU_SRAM_PARA1 under the irq lock, so that we can add this to the frame updates at interrupt time when disabling a plane. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: move regs into armada_plane_workRussell King
Move the register update structure out of the overlay private structure into armada_plane_work, as this is common to both the primary and overlay planes. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: move event sending into armada_plane_workRussell King
Move the sending of events into the armada_plane_work structure, and combine the processing in armada_drm_plane_work_call(). Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: move fb retirement into armada_plane_workRussell King
Both the primary and overlay planes retire framebuffers in a similar manner; this can be consolidated by moving the retirement up to the armada_plane_work layer. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: move overlay plane work out from under spinlockRussell King
Move the overlay plane work out from under the spinlock so that both the primary and overlay planes run their work in the same context. This is necessary so that we can use frame works with the overlay plane. However, we must update the CRTC registers under the spinlock, so fix up the overlay code for that. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: clear plane enable bit when disablingRussell King
Clear the plane enable bit in the software state within armada_drm_plane_disable() when disabling either the primary or overlay planes. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: clean up armada_drm_crtc_plane_disable()Russell King
Merge armada_drm_primary_disable() into armada_drm_crtc_plane_disable() and rename to armada_drm_plane_disable(). Use this to simplify armada_ovl_plane_disable(). Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: allow the primary plane to be disabledRussell King
Add our own hook to allow the primary plane to be disabled. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2017-12-08drm/armada: wait and cancel any pending frame work at disableRussell King
Wait for a second, and if we time out, cancel any pending work when disabling the primary plane. This ensures that any pending work is completed or cleaned up prior to the disable taking effect. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: add work cancel callbackRussell King
Add a work cancel callback, so that work items can add functionality to clean themselves up when they are cancelled. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: store plane in armada_plane_workRussell King
Store the plane in the armada_plane_work structure rather than passing it around; it doesn't get used very much in the work structures, so passing it around is a needless expense. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: add a common frame work allocatorRussell King
Add and use a common frame work allocator, initialising the frame work to a sane state. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: remove armada_drm_plane_work_cancel() return valueRussell King
armada_drm_plane_work_cancel()'s returned work structure is never used or referenced, so it's pointless returning it. It's also pointless because the caller doesn't have a clue what kind of work structure it is. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: fix YUV planar format framebuffer offsetsdrm-armada-fixes-4.15Russell King
We weren't correctly calculating the YUV planar offsets for subsampled chroma planes correctly - fix up the coordinates for planes 1 and 2. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: improve efficiency of armada_drm_plane_calc_addrs()Russell King
Lookup the drm_format_info structure once when computing all the framebuffer plane addresses by using drm_format_info(), rather than repetitive lookups via drm_format_plane_cpp(). Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: fix UV swap codeRussell King
The UV swap code was not always programming things correctly when the source origin box has been offset. Fix this. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: fix SRAM powerdownRussell King
Avoid powering down the overlay SRAM banks when disabling the primary plane, thereby masking any overlay video. This feature is supposed to allow us to cut the bandwidth required while displaying full-frame overlay video. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-12-08drm/armada: fix leak of crtc structureRussell King

Jake fixes a regression issue with older firmware, where we were using the NVM lock to synchronize NVM reads for all devices and firmware versions, yet this caused issues with older firmware prior to version 1.5. Fixed this by only grabbing the lock for newer devices and firmware version 1.5 or newer. Zijie Pan fixes the calculation of the i40e VF MAC addresses, where it was possible to increment to the next MAC entry without calling i40e_add_mac_filter(). Amritha removes the upper limit of 64 queues on a channel VSI since the upper bound is determined by the VSI's num_queue_pairs. Filip fixes an issue during FLR resets, where should have been checking for upcoming core reset and if so, just return with I40E_ERR_NOT_READY. Alan fixes the notifying clients of l2 parameters by copying the parameters to the client instance struct and re-organizes the priority in which the client tasks fire so that if the flag for notifying l2 params is set, it will trigger before the client open task. Also fixed the promiscuous settings after reset for all the VSI's. Brian King from IBM fixes an issue seen on Power systems which would result in skb list corruption and eventual kernel oops. Brian provides the same fix for nearly all our drivers, to replace the read_barrier_depends with smp_rmb() to ensure loads are ordered with respect to the load of tx_buffer->next_to_watch. ==================== Signed-off-by: David S.

Among others: - Limit offload to cls_bpf and XDP program types only. - Move device validation into the driver and don't make any assumptions about the device in the classifier due to shared blocks semantics. - Don't pass offloaded XDP program into the driver when it should be run in native XDP instead. Offloaded ones are not JITed for the host in such cases. - Don't destroy device offload state when moved to another namespace. - Revert dumping offload info into user space for now, since ifindex alone is not sufficient. This will be redone properly for bpf-next tree. 2) Fix test_verifier to avoid using bpf_probe_write_user() helper in test cases, since it's dumping a warning into kernel log which may confuse users when only running tests. Switch to use bpf_trace_printk() instead, from Yonghong. 3) Several fixes for correcting ARG_CONST_SIZE_OR_ZERO semantics before it becomes uabi, from Gianluca. More specifically: - Add a type ARG_PTR_TO_MEM_OR_NULL that is used only by bpf_csum_diff(), where the argument is either a valid pointer or NULL. The subsequent ARG_CONST_SIZE_OR_ZERO then enforces a valid pointer in case of non-0 size or a valid pointer or NULL in case of size 0. Given that, the semantics for ARG_PTR_TO_MEM in combination with ARG_CONST_SIZE_OR_ZERO are now such that in case of size 0, the pointer must always be valid and cannot be NULL. This fix in semantics allows for bpf_probe_read() to drop the recently added size == 0 check in the helper that would become part of uabi otherwise once released. At the same time we can then fix bpf_probe_read_str() and bpf_perf_event_output() to use ARG_CONST_SIZE_OR_ZERO instead of ARG_CONST_SIZE in order to fix recently reported issues by Arnaldo et al, where LLVM optimizes two boundary checks into a single one for unknown variables where the verifier looses track of the variable bounds and thus rejects valid programs otherwise. 4) A fix for the verifier for the case when it detects comparison of two constants where the branch is guaranteed to not be taken at runtime. Verifier will rightfully prune the exploration of such paths, but we still pass the program to JITs, where they would complain about using reserved fields, etc. Track such dead instructions and sanitize them with mov r0,r0. Rejection is not possible since LLVM may generate them for valid C code and doesn't do as much data flow analysis as verifier. For bpf-next we might implement removal of such dead code and adjust branches instead. Fix from Alexei. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2017-11-24net: accept UFO datagrams from tuntap and packetWillem de Bruijn
Tuntap and similar devices can inject GSO packets. Accept type VIRTIO_NET_HDR_GSO_UDP, even though not generating UFO natively. Processes are expected to use feature negotiation such as TUNSETOFFLOAD to detect supported offload types and refrain from injecting other packets. This process breaks down with live migration: guest kernels do not renegotiate flags, so destination hosts need to expose all features that the source host does. Partially revert the UFO removal from 182e0b6b5846~1..d9d30adf5677. This patch introduces nearly(*) no new code to simplify verification. It brings back verbatim tuntap UFO negotiation, VIRTIO_NET_HDR_GSO_UDP insertion and software UFO segmentation. It does not reinstate protocol stack support, hardware offload (NETIF_F_UFO), SKB_GSO_UDP tunneling in SKB_GSO_SOFTWARE or reception of VIRTIO_NET_HDR_GSO_UDP packets in tuntap. To support SKB_GSO_UDP reappearing in the stack, also reinstate logic in act_csum and openvswitch. Achieve equivalence with v4.13 HEAD by squashing in commit 939912216fa8 ("net: skb_needs_check() removes CHECKSUM_UNNECESSARY check for tx.") and reverting commit 8d63bee643f1 ("net: avoid skb_warn_bad_offload false positives on UFO"). (*) To avoid having to bring back skb_shinfo(skb)->ip6_frag_id, ipv6_proxy_select_ident is changed to return a __be32 and this is assigned directly to the frag_hdr. Also, SKB_GSO_UDP is inserted at the end of the enum to minimize code churn. Tested Booted a v4.13 guest kernel with QEMU. On a host kernel before this patch `ethtool -k eth0` shows UFO disabled. After the patch, it is enabled, same as on a v4.13 host kernel. A UFO packet sent from the guest appears on the tap device: host: nc -l -p -u 8000 & tcpdump -n -i tap0 guest: dd if=/dev/zero of=payload.txt bs=1 count=2000 nc -u 192.16.1.1 8000 < payload.txt Direct tap to tap transmission of VIRTIO_NET_HDR_GSO_UDP succeeds, packets arriving fragmented: ./with_tap_pair.sh ./tap_send_ufo tap0 tap1 (from https://github.com/wdebruij/kerneltools/tree/master/tests) Changes v1 -> v2 - simplified set_offload change (review comment) - documented test procedure Link: http://lkml.kernel.org/r/<CAF=yD-LuUeDuL9YWPJD9ykOZ0QCjNeznPDr6whqZ9NGMNF12Mw@mail.gmail.com> Fixes: fb652fdfe837 ("macvlan/macvtap: Remove NETIF_F_UFO advertisement.")

2017-11-24net: realtek: r8169: implement set_link_ksettings()Tobias Jakobi
Commit 6fa1ba61520576cf1346c4ff09a056f2950cb3bf partially implemented the new ethtool API, by replacing get_settings() with get_link_ksettings(). This breaks ethtool, since the userspace tool (according to the new API specs) never tries the legacy set() call, when the new get() call succeeds. All attempts to chance some setting from userspace result in: > Cannot set new settings: Operation not supported Implement the missing set() call.
