2022-03-01PM: suspend: fix return value of __setup handlerRandy Dunlap

2022-03-01PM: domains: Prevent power off for parent unless child is in deepest stateUlf Hansson
A PM domain managed by genpd may support multiple idlestates (power-off states). During genpd_power_off() a genpd governor may be asked to select one of the idlestates based upon the dev PM QoS constraints, for example. However, there is a problem with the behaviour around this in genpd. More precisely, a parent-domain is allowed to be powered off, no matter of what idlestate that has been selected for the child-domain. For the stm32mp1 platform from STMicro, this behaviour doesn't play well. Instead, the parent-domain must not be powered off, unless the deepest idlestate has been selected for the child-domain. As the current behaviour in genpd is quite questionable anyway, let's simply change it into what is needed by the stm32mp1 platform. If it surprisingly turns out that other platforms may need a different behaviour from genpd, then we will have to revisit this to find a way to make it configurable.

2022-03-01HID: vivaldi: fix sysfs attributes leakDmitry Torokhov
The driver creates the top row map sysfs attribute in input_configured() method; unfortunately we do not have a callback that is executed when HID interface is unbound, thus we are leaking these sysfs attributes, for example when device is disconnected. To fix it let's switch to managed version of adding sysfs attributes which will ensure that they are destroyed when the driver is unbound.

2022-03-01xfrm: fix tunnel model fragmentation behaviorLina Wang
in tunnel mode, if outer interface(ipv4) is less, it is easily to let inner IPV6 mtu be less than 1280. If so, a Packet Too Big ICMPV6 message is received. When send again, packets are fragmentized with 1280, they are still rejected with ICMPV6(Packet Too Big) by xfrmi_xmit2(). According to RFC4213 Section3.2.2: if (IPv4 path MTU - 20) is less than 1280 if packet is larger than 1280 bytes Send ICMPv6 "packet too big" with MTU=1280 Drop packet else Encapsulate but do not set the Don't Fragment flag in the IPv4 header. The resulting IPv4 packet might be fragmented by the IPv4 layer on the encapsulator or by some router along the IPv4 path. endif else if packet is larger than (IPv4 path MTU - 20) Send ICMPv6 "packet too big" with MTU = (IPv4 path MTU - 20). Drop packet. else Encapsulate and set the Don't Fragment flag in the IPv4 header. endif endif Packets should be fragmentized with ipv4 outer interface, so change it. After it is fragemtized with ipv4, there will be double fragmenation. No.48 & No.51 are ipv6 fragment packets, No.48 is double fragmentized, then tunneled with IPv4(No.49& No.50), which obey spec.

2022-03-01netfilter: nf_queue: handle socket prefetchFlorian Westphal
In case someone combines bpf socket assign and nf_queue, then we will queue an skb who references a struct sock that did not have its reference count incremented. As we leave rcu protection, there is no guarantee that skb->sk is still valid. For refcount-less skb->sk case, try to increment the reference count and then override the destructor. In case of failure we have two choices: orphan the skb and 'delete' preselect or let nf_queue() drop the packet. Do the latter, it should not happen during normal operation.

2022-03-01mac80211: treat some SAE auth steps as finalJohannes Berg
When we get anti-clogging token required (added by the commit mentioned below), or the other status codes added by the later commit 4e56cde15f7d ("mac80211: Handle special status codes in SAE commit") we currently just pretend (towards the internal state machine of authentication) that we didn't receive anything. This has the undesirable consequence of retransmitting the prior frame, which is not expected, because the timer is still armed. If we just disarm the timer at that point, it would result in the undesirable side effect of being in this state indefinitely if userspace crashes, or so. So to fix this, reset the timer and set a new auth_data->waiting in order to have no more retransmissions, but to have the data destroyed when the timer actually fires, which will only happen if userspace didn't continue (i.e. crashed or abandoned it.)

2022-03-01irqchip/qcom-pdc: Fix broken lockingMarc Zyngier
pdc_enable_intr() serves as a primitive to qcom_pdc_gic_{en,dis}able, and has a raw spinlock for mutual exclusion, which is uses with interruptible primitives. This means that this critical section can itself be interrupted. Should the interrupt also be a PDC interrupt, and the endpoint driver perform an irq_disable() on that interrupt, we end-up in a deadlock.

A careful look at the way the PDC driver works shows that: - all interrupts are in the same space - all interrupts are treated the same And yet the driver creates two domains based on whether the interrupt gets mapped directly or from the pinctrl code, which is obviously a waste of resources. Kill the non-wakeup domain and unify all the interrupt handling. Signed-off-by: Marc Zyngier <maz@kernel.org> Link: https://lore.kernel.org/r/20220224101226.88373-3-maz@kernel.org

PDC_NO_PARENT_IRQ is pretty pointless, as all it indicates is that the PDC terminates the interrupt hierarchy. Which is exactly the same as not having a mapping in the GIC space. This is also bad practice to treat the absence of a hwirq as a hwirq itself. Just explicitly use the region mapping pointer, and drop the definition.

2022-03-01soc: mediatek: mt8192-mmsys: Fix dither to dsi0 path's input selAngeloGioacchino Del Regno
In commit d687e056a18f ("soc: mediatek: mmsys: Add mt8192 mmsys routing table"), the mmsys routing table for mt8192 was introduced but the input selector for DITHER->DSI0 has no value assigned to it. This means that we are clearing bit 0 instead of setting it, blocking communication between these two blocks; due to that, any display that is connected to DSI0 will not work, as no data will go through. The effect of that issue is that, during bootup, the DRM will block for some time, while atomically waiting for a vblank that never happens; later, the situation doesn't get better, leaving the display in a non-functional state. To fix this issue, fix the route entry in the table by assigning the dither input selector to MT8192_DISP_DSI0_SEL_IN.

Interrupt() resource ACPI/x86 devices with a Cherry Trail SoC should have a GpioInt + a regular GPIO ACPI resource in their ACPI tables. Some CHT devices have a bug, where the also is bogus interrupt resource (likely copied from a previous Bay Trail based generation of the device).

2022-02-28pinctrl: sunxi: Use unique lockdep classes for IRQsSamuel Holland
This driver, like several others, uses a chained IRQ for each GPIO bank, and forwards .irq_set_wake to the GPIO bank's upstream IRQ. As a result, a call to irq_set_irq_wake() needs to lock both the upstream and downstream irq_desc's. Lockdep considers this to be a possible deadlock when the irq_desc's share lockdep classes, which they do by default: ============================================ WARNING: possible recursive locking detected 5.17.0-rc3-00394-gc849047c2473 #1 Not tainted -------------------------------------------- init/307 is trying to acquire lock: c2dfe27c (&irq_desc_lock_class){-.-.}-{2:2}, at: __irq_get_desc_lock+0x58/0xa0 but task is already holding lock: c3c0ac7c (&irq_desc_lock_class){-.-.}-{2:2}, at: __irq_get_desc_lock+0x58/0xa0 other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(&irq_desc_lock_class); lock(&irq_desc_lock_class); *** DEADLOCK *** May be due to missing lock nesting notation 4 locks held by init/307: #0: c1f29f18 (system_transition_mutex){+.+.}-{3:3}, at: __do_sys_reboot+0x90/0x23c #1: c20f7760 (&dev->mutex){....}-{3:3}, at: device_shutdown+0xf4/0x224 #2: c2e804d8 (&dev->mutex){....}-{3:3}, at: device_shutdown+0x104/0x224 #3: c3c0ac7c (&irq_desc_lock_class){-.-.}-{2:2}, at: __irq_get_desc_lock+0x58/0xa0 stack backtrace: CPU: 0 PID: 307 Comm: init Not tainted 5.17.0-rc3-00394-gc849047c2473 #1 Hardware name: Allwinner sun8i Family unwind_backtrace from show_stack+0x10/0x14 show_stack from dump_stack_lvl+0x68/0x90 dump_stack_lvl from __lock_acquire+0x1680/0x31a0 __lock_acquire from lock_acquire+0x148/0x3dc lock_acquire from _raw_spin_lock_irqsave+0x50/0x6c _raw_spin_lock_irqsave from __irq_get_desc_lock+0x58/0xa0 __irq_get_desc_lock from irq_set_irq_wake+0x2c/0x19c irq_set_irq_wake from irq_set_irq_wake+0x13c/0x19c [tail call from sunxi_pinctrl_irq_set_wake] irq_set_irq_wake from gpio_keys_suspend+0x80/0x1a4 gpio_keys_suspend from gpio_keys_shutdown+0x10/0x2c gpio_keys_shutdown from device_shutdown+0x180/0x224 device_shutdown from __do_sys_reboot+0x134/0x23c __do_sys_reboot from ret_fast_syscall+0x0/0x1c However, this can never deadlock because the upstream and downstream IRQs are never the same (nor do they even involve the same irqchip).

2022-02-28netfilter: egress: silence egress hook lockdep splatsFlorian Westphal
Netfilter assumes its called with rcu_read_lock held, but in egress hook case it may be called with BH readlock. This triggers lockdep splat. In order to avoid to change all rcu_dereference() to rcu_dereference_check(..., rcu_read_lock_bh_held()), wrap nf_hook_slow with read lock/unlock pair.
