2022-03-01net/sched: act_ct: Fix flow table lookup failure with no originating ifindexPaul Blakey
After cited commit optimizted hw insertion, flow table entries are populated with ifindex information which was intended to only be used for HW offload. This tuple ifindex is hashed in the flow table key, so it must be filled for lookup to be successful. But tuple ifindex is only relevant for the netfilter flowtables (nft), so it's not filled in act_ct flow table lookup, resulting in lookup failure, and no SW offload and no offload teardown for TCP connection FIN/RST packets. To fix this, add new tc ifindex field to tuple, which will only be used for offloading, not for lookup, as it will not be part of the tuple hash.

2022-03-01s390/extable: fix exception table sortingHeiko Carstens
s390 has a swap_ex_entry_fixup function, however it is not being used since common code expects a swap_ex_entry_fixup define. If it is not defined the default implementation will be used. So fix this by adding a proper define. However also the implementation of the function must be fixed, since a NULL value for handler has a special meaning and must not be adjusted. Luckily all of this doesn't fix a real bug currently: the main extable is correctly sorted during build time, and for runtime sorting there is currently no case where the handler field is not NULL.

2022-03-01s390/ftrace: fix arch_ftrace_get_regs implementationHeiko Carstens
arch_ftrace_get_regs is supposed to return a struct pt_regs pointer only if the pt_regs structure contains all register contents, which means it must have been populated when created via ftrace_regs_caller. If it was populated via ftrace_caller the contents are not complete (the psw mask part is missing), and therefore a NULL pointer needs be returned. The current code incorrectly always returns a struct pt_regs pointer. Fix this by adding another pt_regs flag which indicates if the contents are complete, and fix arch_ftrace_get_regs accordingly.

ftrace_caller was used for both ftrace_caller and ftrace_regs_caller, which means that the target address of the hotpatch trampoline was never updated. With commit 894979689d3a ("s390/ftrace: provide separate ftrace_caller/ftrace_regs_caller implementations") a separate ftrace_regs_caller entry point was implemeted, however it was forgotten to implement the necessary changes for ftrace_modify_call and ftrace_make_call, where the branch target has to be modified accordingly.

2022-03-01binfmt_elf: Avoid total_mapping_size for ET_EXECKees Cook
Partially revert commit 5f501d555653 ("binfmt_elf: reintroduce using MAP_FIXED_NOREPLACE"), which applied the ET_DYN "total_mapping_size" logic also to ET_EXEC. At least ia64 has ET_EXEC PT_LOAD segments that are not virtual-address contiguous (but _are_ file-offset contiguous). This would result in a giant mapping attempting to cover the entire span, including the virtual address range hole, and well beyond the size of the ELF file itself, causing the kernel to refuse to load it. For example: $ readelf -lW /usr/bin/gcc ... Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz ... ... LOAD 0x000000 0x4000000000000000 0x4000000000000000 0x00b5a0 0x00b5a0 ...

Ironically, this is the reverse of the problem that originally caused problems with MAP_FIXED_NOREPLACE: overlapping PT_LOAD segments. Future work could restore full coverage if load_elf_binary() were to perform mappings in a separate phase from the loading (where it could resolve both overlaps and holes).

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.)

It corrects the apps SMMU interrupts defintion by adding a missing interrupt in the list. Lastly it disables the Qualcomm crypto hardware (for now) on the Lenovo Yoga C630, to prevent the cryptomanager tests during boot from crashing the device. * tag 'qcom-arm64-fixes-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: arm64: dts: qcom: c630: disable crypto due to serror arm64: dts: qcom: sm8450: fix apps_smmu interrupts arm64: dts: qcom: sm8450: enable GCC_USB3_0_CLKREF_EN for usb arm64: dts: qcom: sm8350: Correct UFS symbol clocks Link: https://lore.kernel.org/r/20220301033526.1801295-1-bjorn.andersson@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

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). The i2c-core-acpi code will assign the bogus, non-working, interrupt resource to client->irq. Add a workaround to fix this up.

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).

2022-02-28drm/bridge: ti-sn65dsi86: Properly undo autosuspendDouglas Anderson
The PM Runtime docs say: Drivers in ->remove() callback should undo the runtime PM changes done in ->probe(). Usually this means calling pm_runtime_disable(), pm_runtime_dont_use_autosuspend() etc. We weren't doing that for autosuspend. Let's do it.

2022-02-28x86/speculation: Use generic retpoline by default on AMDKim Phillips
AMD retpoline may be susceptible to speculation. The speculation execution window for an incorrect indirect branch prediction using LFENCE/JMP sequence may potentially be large enough to allow exploitation using Spectre V2. By default, don't use retpoline,lfence on AMD. Instead, use the generic retpoline. Signed-off-by: Kim Phillips <kim.phillips@amd.com> Signed-off-by: Borislav Petkov <bp@suse.de>
2022-02-28igc: igc_write_phy_reg_gpy: drop premature returnSasha Neftin
Similar to "igc_read_phy_reg_gpy: drop premature return" patch. igc_write_phy_reg_gpy checks the return value from igc_write_phy_reg_mdic and if it's not 0, returns immediately. By doing this, it leaves the HW semaphore in the acquired state. Drop this premature return statement, the function returns after releasing the semaphore immediately anyway.
