2021-10-15eeprom: 93xx46: fix MODULE_DEVICE_TABLEArnd Bergmann
The newly added SPI device ID table does not work because the entry is incorrectly copied from the OF device table. During build testing, this shows as a compile failure when building it as a loadable module: drivers/misc/eeprom/eeprom_93xx46.c:424:1: error: redefinition of '__mod_of__eeprom_93xx46_of_table_device_table' MODULE_DEVICE_TABLE(of, eeprom_93xx46_of_table); Change the entry to refer to the correct symbol.

2021-10-15ALSA: hda/realtek: Fixes HP Spectre x360 15-eb1xxx speakersDavide Baldo
In laptop 'HP Spectre x360 Convertible 15-eb1xxx/8811' both front and rear speakers are silent, this patch fixes that by overriding the pin layout and by initializing the amplifier which needs a GPIO pin to be set to 1 then 0, similar to the existing HP Spectre x360 14 model. In order to have volume control, both front and rear speakers were forced to use the DAC1. This patch also correctly map the mute LED but since there is no microphone on/off switch exposed by the alsa subsystem it never turns on by itself. There are still known audio issues in this laptop: headset microphone doesn't work, the button to mute/unmute microphone is not yet mapped, the LED of the mute/unmute speakers doesn't seems to be exposed via GPIO and never turns on.

As per discussion at: https://github.com/szszoke/sennheiser-gsp670-pulseaudio-profile/issues/13 The GSP670 has 2 playback and 1 recording device that by default are detected in an incompatible order for alsa.

2021-10-15drm/nouveau/fifo: Reinstate the correct engine bit programmingMarek Vasut
Commit 64f7c698bea9 ("drm/nouveau/fifo: add engine_id hook") replaced fifo/chang84.c g84_fifo_chan_engine() call with an indirect call of fifo/g84.c g84_fifo_engine_id(). The G84_FIFO_ENGN_* values returned from the later g84_fifo_engine_id() are incremented by 1 compared to the previous g84_fifo_chan_engine() return values. This is fine either way for most of the code, except this one line where an engine bit programmed into the hardware is derived from the return value. Decrement the return value accordingly, otherwise the wrong engine bit is programmed into the hardware and that leads to the following failure: nouveau 0000:01:00.0: gr: 00000030 [ILLEGAL_MTHD ILLEGAL_CLASS] ch 1 [003fbce000 DRM] subc 3 class 0000 mthd 085c data 00000420 On the following hardware: lspci -s 01:00.0 01:00.0 VGA compatible controller: NVIDIA Corporation GT216GLM [Quadro FX 880M] (rev a2) lspci -ns 01:00.0 01:00.0 0300: 10de:0a3c (rev a2) Fixes: 64f7c698bea9 ("drm/nouveau/fifo: add engine_id hook") Signed-off-by: Marek Vasut <marex@denx.de> Cc: <stable@vger.kernel.org> # 5.12+ Cc: Ben Skeggs <bskeggs@redhat.com> Cc: Karol Herbst <kherbst@redhat.com> Cc: Lyude Paul <lyude@redhat.com> Reviewed-by: Karol Herbst <kherbst@redhat.com> Reviewed-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Karol Herbst <kherbst@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211007214117.231472-1-marex@denx.de Signed-off-by: Dave Airlie <airlied@redhat.com>
2021-10-15drm/hyperv: Fix double mouse pointersDexuan Cui
Hyper-V supports a hardware cursor feature. It is not used by Linux VM, but the Hyper-V host still draws a point as an extra mouse pointer, which is unwanted, especially when Xorg is running. The hyperv_fb driver uses synthvid_send_ptr() to hide the unwanted pointer. When the hyperv_drm driver was developed, the function synthvid_send_ptr() was not copied from the hyperv_fb driver. Fix the issue by adding the function into hyperv_drm.

2021-10-15drm/edid: In connector_bad_edid() cap num_of_ext by num_blocks readDouglas Anderson
In commit e11f5bd8228f ("drm: Add support for DP 1.4 Compliance edid corruption test") the function connector_bad_edid() started assuming that the memory for the EDID passed to it was big enough to hold `edid[0x7e] + 1` blocks of data (1 extra for the base block). It completely ignored the fact that the function was passed `num_blocks` which indicated how much memory had been allocated for the EDID. Let's fix this by adding a bounds check. This is important for handling the case where there's an error in the first block of the EDID. In that case we will call connector_bad_edid() without having re-allocated memory based on `edid[0x7e]`.

Currently, NDA_FLAGS_EXT flags allow a maximum of 24 bits to be used for extended neighbor flags. These are eventually fed into neigh->flags by shifting with NTF_EXT_SHIFT as per commit 2c611ad97a82 ("net, neigh: Extend neigh->flags to 32 bit to allow for extensions"). If really ever needed in future, the full 32 bits from NDA_FLAGS_EXT can be used, it would only require to move neigh->flags from u32 to u64 inside the kernel. Add a build-time assertion such that when extending the NTF_EXT_MASK with new bits, we'll trigger an error once we surpass the 24th bit. This assumes that no bit holes in new NTF_EXT_* flags will slip in from UAPI, but I think this is reasonable to assume.

2021-10-14netfilter: ip6t_rt: fix rt0_hdr parsing in rt_mt6Xin Long
In rt_mt6(), when it's a nonlinear skb, the 1st skb_header_pointer() only copies sizeof(struct ipv6_rt_hdr) to _route that rh points to. The access by ((const struct rt0_hdr *)rh)->reserved will overflow the buffer. So this access should be moved below the 2nd call to skb_header_pointer(). Besides, after the 2nd skb_header_pointer(), its return value should also be checked, othersize, *rp may cause null-pointer-ref. v1->v2: - clean up some old debugging log.

2021-10-14af_packet: Introduce egress hookPablo Neira Ayuso
Add egress hook for AF_PACKET sockets that have the PACKET_QDISC_BYPASS socket option set to on, which allows packets to escape without being filtered in the egress path. This patch only updates the AF_PACKET path, it does not update dev_direct_xmit() so the XDP infrastructure has a chance to bypass Netfilter.

2021-10-14netfilter: Introduce egress hookLukas Wunner
Support classifying packets with netfilter on egress to satisfy user requirements such as: * outbound security policies for containers (Laura) * filtering and mangling intra-node Direct Server Return (DSR) traffic on a load balancer (Laura) * filtering locally generated traffic coming in through AF_PACKET, such as local ARP traffic generated for clustering purposes or DHCP (Laura; the AF_PACKET plumbing is contained in a follow-up commit) * L2 filtering from ingress and egress for AVB (Audio Video Bridging) and gPTP with nftables (Pablo) * in the future: in-kernel NAT64/NAT46 (Pablo) The egress hook introduced herein complements the ingress hook added by commit e687ad60af09 ("netfilter: add netfilter ingress hook after handle_ing() under unique static key"). A patch for nftables to hook up egress rules from user space has been submitted separately, so users may immediately take advantage of the feature. Alternatively or in addition to netfilter, packets can be classified with traffic control (tc). On ingress, packets are classified first by tc, then by netfilter. On egress, the order is reversed for symmetry. Conceptually, tc and netfilter can be thought of as layers, with netfilter layered above tc. Traffic control is capable of redirecting packets to another interface (man 8 tc-mirred). E.g., an ingress packet may be redirected from the host namespace to a container via a veth connection: tc ingress (host) -> tc egress (veth host) -> tc ingress (veth container) In this case, netfilter egress classifying is not performed when leaving the host namespace! That's because the packet is still on the tc layer. If tc redirects the packet to a physical interface in the host namespace such that it leaves the system, the packet is never subjected to netfilter egress classifying. That is only logical since it hasn't passed through netfilter ingress classifying either. Packets can alternatively be redirected at the netfilter layer using nft fwd. Such a packet *is* subjected to netfilter egress classifying since it has reached the netfilter layer. Internally, the skb->nf_skip_egress flag controls whether netfilter is invoked on egress by __dev_queue_xmit(). Because __dev_queue_xmit() may be called recursively by tunnel drivers such as vxlan, the flag is reverted to false after sch_handle_egress(). This ensures that netfilter is applied both on the overlay and underlying network. Interaction between tc and netfilter is possible by setting and querying skb->mark. If netfilter egress classifying is not enabled on any interface, it is patched out of the data path by way of a static_key and doesn't make a performance difference that is discernible from noise: Before: 1537 1538 1538 1537 1538 1537 Mb/sec After: 1536 1534 1539 1539 1539 1540 Mb/sec Before + tc accept: 1418 1418 1418 1419 1419 1418 Mb/sec After + tc accept: 1419 1424 1418 1419 1422 1420 Mb/sec Before + tc drop: 1620 1619 1619 1619 1620 1620 Mb/sec After + tc drop: 1616 1624 1625 1624 1622 1619 Mb/sec When netfilter egress classifying is enabled on at least one interface, a minimal performance penalty is incurred for every egress packet, even if the interface it's transmitted over doesn't have any netfilter egress rules configured. That is caused by checking dev->nf_hooks_egress against NULL. Measurements were performed on a Core i7-3615QM.

2021-10-14libperf tests: Fix test_stat_cpuShunsuke Nakamura
The `cpu` argument of perf_evsel__read() must specify the cpu index. perf_cpu_map__for_each_cpu() is for iterating the cpu number (not index) and is thus not appropriate for use with perf_evsel__read(). So, if there is an offline CPU, the cpu number specified in the argument may point out of range because the cpu number and the cpu index are different. Fix test_stat_cpu().
