2020-11-30powerpc/pseries: Pass MSI affinity to irq_create_mapping()Laurent Vivier1-1/+2
With virtio multiqueue, normally each queue IRQ is mapped to a CPU. Commit 0d9f0a52c8b9f ("virtio_scsi: use virtio IRQ affinity") exposed an existing shortcoming of the arch code by moving virtio_scsi to the automatic IRQ affinity assignment. The affinity is correctly computed in msi_desc but this is not applied to the system IRQs. It appears the affinity is correctly passed to rtas_setup_msi_irqs() but lost at this point and never passed to irq_domain_alloc_descs() (see commit 06ee6d571f0e ("genirq: Add affinity hint to irq allocation")) because irq_create_mapping() doesn't take an affinity parameter. Use the new irq_create_mapping_affinity() function, which allows to forward the affinity setting from rtas_setup_msi_irqs() to irq_domain_alloc_descs(). With this change, the virtqueues are correctly dispatched between the CPUs on pseries.

2020-11-30genirq/irqdomain: Add an irq_create_mapping_affinity() functionLaurent Vivier2-7/+18
There is currently no way to convey the affinity of an interrupt via irq_create_mapping(), which creates issues for devices that expect that affinity to be managed by the kernel. In order to sort this out, rename irq_create_mapping() to irq_create_mapping_affinity() with an additional affinity parameter that can be passed down to irq_domain_alloc_descs(). irq_create_mapping() is re-implemented as a wrapper around irq_create_mapping_affinity(). No functional change.

2020-11-30speakup: Reject setting the speakup line discipline outside of speakupSamuel Thibault1-14/+23
Speakup exposing a line discipline allows userland to try to use it, while it is deemed to be useless, and thus uselessly exposes potential bugs. One of them is simply that in such a case if the line sends data, spk_ttyio_receive_buf2 is called and crashes since spk_ttyio_synth is NULL. This change restricts the use of the speakup line discipline to speakup drivers, thus avoiding such kind of issues altogether.

2020-11-29drm/panel: sony-acx565akm: Fix race condition in probeSebastian Reichel1-1/+1
The probe routine acquires the reset GPIO using GPIOD_OUT_LOW. Directly afterwards it calls acx565akm_detect(), which sets the GPIO value to HIGH. If the bootloader initialized the GPIO to HIGH before the probe routine was called, there is only a very short time period of a few instructions where the reset signal is LOW. Exact time depends on compiler optimizations, kernel configuration and alignment of the stars, but I expect it to be always way less than 10us. There are no public datasheets for the panel, but acx565akm_power_on() has a comment with timings and reset period should be at least 10us. So this potentially brings the panel into a half-reset state. The result is, that panel may not work after boot and can get into a working state by re-enabling it (e.g. by blanking + unblanking), since that does a clean reset cycle. This bug has recently been hit by Ivaylo Dimitrov, but there are some older reports which are probably the same bug. At least Tony Lindgren, Peter Ujfalusi and Jarkko Nikula have experienced it in 2017 describing the blank/unblank procedure as possible workaround. Note, that the bug really goes back in time. It has originally been introduced in the predecessor of the omapfb driver in commit 3c45d05be382 ("OMAPDSS: acx565akm panel: handle gpios in panel driver") in 2012. That driver eventually got replaced by a newer one, which had the bug from the beginning in commit 84192742d9c2 ("OMAPDSS: Add Sony ACX565AKM panel driver") and still exists in fbdev world. That driver has later been copied to omapdrm and then was used as a basis for this driver. Last but not least the omapdrm specific driver has been removed in commit 45f16c82db7e ("drm/omap: displays: Remove unused panel drivers").

Netfilter changes PACKET_OTHERHOST to PACKET_HOST before invoking the hooks as, while it's an expected value for a bridge, routing expects PACKET_HOST. The change is undone later on after hook traversal. This can be seen with pairs of functions updating skb>pkt_type and then reverting it to its original value: For hook NF_INET_PRE_ROUTING: setup_pre_routing / br_nf_pre_routing_finish For hook NF_INET_FORWARD: br_nf_forward_ip / br_nf_forward_finish But the third case where netfilter does this, for hook NF_INET_POST_ROUTING, the packet type is changed in br_nf_post_routing but never reverted. A comment says: /* We assume any code from br_dev_queue_push_xmit onwards doesn't care * about the value of skb->pkt_type. */ But when having a tunnel (say vxlan) attached to a bridge we have the following call trace: br_nf_pre_routing br_nf_pre_routing_ipv6 br_nf_pre_routing_finish br_nf_forward_ip br_nf_forward_finish br_nf_post_routing <- pkt_type is updated to PACKET_HOST br_nf_dev_queue_xmit <- but not reverted to its original value vxlan_xmit vxlan_xmit_one skb_tunnel_check_pmtu <- a check on pkt_type is performed In this specific case, this creates issues such as when an ICMPv6 PTB should be sent back. When CONFIG_BRIDGE_NETFILTER is enabled, the PTB isn't sent (as skb_tunnel_check_pmtu checks if pkt_type is PACKET_HOST and returns early). If the comment is right and no one cares about the value of skb->pkt_type after br_dev_queue_push_xmit (which isn't true), resetting it to its original value should be safe.

2020-11-28ALSA: hda/realtek: Fix bass speaker DAC assignment on Asus Zephyrus G14Takashi Iwai1-6/+20
ASUS Zephyrus G14 has two speaker pins, and the auto-parser tries to assign an individual DAC to each pin as much as possible. Unfortunately the third DAC has no volume control unlike the two DACs, and this resulted in the inconsistent speaker volumes. As a workaround, wire both speaker pins to the same DAC by modifying the existing quirk (ALC289_FIXUP_ASUS_GA401) applied to this device. Since this quirk entry is chained by another, we need to avoid applying the DAC assignment change for it. Luckily, there is another quirk entry (ALC289_FIXUP_ASUS_GA502) doing the very same thing, so we can chain to the GA502 quirk instead. Note that this patch uses a new flag of the generic parser, obey_preferred_dacs, for enforcing the DACs.

2020-11-28ALSA: hda/generic: Add option to enforce preferred_dacs pairsTakashi Iwai2-4/+9
The generic parser accepts the preferred_dacs[] pairs as a hint for assigning a DAC to each pin, but this hint doesn't work always effectively. Currently it's merely a secondary choice after the trial with the path index failed. This made sometimes it difficult to assign DACs without mimicking the connection list and/or the badness table. This patch adds a new flag, obey_preferred_dacs, that changes the behavior of the parser. As its name stands, the parser obeys the given preferred_dacs[] pairs by skipping the path index matching and giving a high penalty if no DAC is assigned by the pairs. This mode will help for assigning the fixed DACs forcibly from the codec driver.
