2024-01-12Merge branch 'mptcp-better-validation-of-mptcpopt_mp_join-option'Jakub Kicinski2-11/+11
Eric Dumazet says: ==================== mptcp: better validation of MPTCPOPT_MP_JOIN option Based on a syzbot report (see 4th patch in the series). We need to be more explicit about which one of the following flag is set by mptcp_parse_option(): - OPTION_MPTCP_MPJ_SYN - OPTION_MPTCP_MPJ_SYNACK - OPTION_MPTCP_MPJ_ACK Then select the appropriate values instead of OPTIONS_MPTCP_MPJ Paolo suggested to do the same for OPTIONS_MPTCP_MPC (5th patch) ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
2024-01-12mptcp: refine opt_mp_capable determinationEric Dumazet1-4/+4
OPTIONS_MPTCP_MPC is a combination of three flags. It would be better to be strict about testing what flag is expected, at least for code readability. mptcp_parse_option() already makes the distinction. - subflow_check_req() should use OPTION_MPTCP_MPC_SYN. - mptcp_subflow_init_cookie_req() should use OPTION_MPTCP_MPC_ACK. - subflow_finish_connect() should use OPTION_MPTCP_MPC_SYNACK - subflow_syn_recv_sock should use OPTION_MPTCP_MPC_ACK Suggested-by: Paolo Abeni <[email protected]> Signed-off-by: Eric Dumazet <[email protected]> Reviewed-by: Simon Horman <[email protected]> Acked-by: Paolo Abeni <[email protected]> Reviewed-by: Mat Martineau <[email protected]> Fixes: 74c7dfbee3e1 ("mptcp: consolidate in_opt sub-options fields in a bitmask") Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>

mptcp_parse_option() currently sets OPTIONS_MPTCP_MPJ, for the three possible cases handled for MPTCPOPT_MP_JOIN option. OPTIONS_MPTCP_MPJ is the combination of three flags: - OPTION_MPTCP_MPJ_SYN - OPTION_MPTCP_MPJ_SYNACK - OPTION_MPTCP_MPJ_ACK This is a problem, because backup, join_id, token, nonce and/or hmac fields could be left uninitialized in some cases.

The kernel sefltest mm/hugepage-vmemmap fails on architectures which has different page size other than 4K. In hugepage-vmemmap page size used is 4k so the pfn calculation will go wrong on systems which has different page size .The length of MAP_HUGETLB memory must be hugepage aligned but in hugepage-vmemmap map length is 2M so this will not get aligned if the system has differnet hugepage size.

2024-01-12mm/memory_hotplug: fix memmap_on_memory sysfs value retrievalSumanth Korikkar1-3/+5
set_memmap_mode() stores the kernel parameter memmap mode as an integer. However, the get_memmap_mode() function utilizes param_get_bool() to fetch the value as a boolean, leading to potential endianness issue. On Big-endian architectures, the memmap_on_memory is consistently displayed as 'N' regardless of its actual status. To address this endianness problem, the solution involves obtaining the mode as an integer. This adjustment ensures the proper display of the memmap_on_memory parameter, presenting it as one of the following options: Force, Y, or N.

2024-01-12kexec: do syscore_shutdown() in kernel_kexecJames Gowans1-0/+1
syscore_shutdown() runs driver and module callbacks to get the system into a state where it can be correctly shut down. In commit 6f389a8f1dd2 ("PM / reboot: call syscore_shutdown() after disable_nonboot_cpus()") syscore_shutdown() was removed from kernel_restart_prepare() and hence got (incorrectly?) removed from the kexec flow. This was innocuous until commit 6735150b6997 ("KVM: Use syscore_ops instead of reboot_notifier to hook restart/shutdown") changed the way that KVM registered its shutdown callbacks, switching from reboot notifiers to syscore_ops.shutdown. As syscore_shutdown() is missing from kexec, KVM's shutdown hook is not run and virtualisation is left enabled on the boot CPU which results in triple faults when switching to the new kernel on Intel x86 VT-x with VMXE enabled. Fix this by adding syscore_shutdown() to the kexec sequence. In terms of where to add it, it is being added after migrating the kexec task to the boot CPU, but before APs are shut down. It is not totally clear if this is the best place: in commit 6f389a8f1dd2 ("PM / reboot: call syscore_shutdown() after disable_nonboot_cpus()") it is stated that "syscore_ops operations should be carried with one CPU on-line and interrupts disabled." APs are only offlined later in machine_shutdown(), so this syscore_shutdown() is being run while APs are still online. This seems to be the correct place as it matches where syscore_shutdown() is run in the reboot and halt flows - they also run it before APs are shut down. The assumption is that the commit message in commit 6f389a8f1dd2 ("PM / reboot: call syscore_shutdown() after disable_nonboot_cpus()") is no longer valid. KVM has been discussed here as it is what broke loudly by not having syscore_shutdown() in kexec, but this change impacts more than just KVM; all drivers/modules which register a syscore_ops.shutdown callback will now be invoked in the kexec flow. Looking at some of them like x86 MCE it is probably more correct to also shut these down during kexec. Maintainers of all drivers which use syscore_ops.shutdown are added on CC for visibility. They are: arch/powerpc/platforms/cell/spu_base.c .shutdown = spu_shutdown, arch/x86/kernel/cpu/mce/core.c .shutdown = mce_syscore_shutdown, arch/x86/kernel/i8259.c .shutdown = i8259A_shutdown, drivers/irqchip/irq-i8259.c .shutdown = i8259A_shutdown, drivers/irqchip/irq-sun6i-r.c .shutdown = sun6i_r_intc_shutdown, drivers/leds/trigger/ledtrig-cpu.c .shutdown = ledtrig_cpu_syscore_shutdown, drivers/power/reset/sc27xx-poweroff.c .shutdown = sc27xx_poweroff_shutdown, kernel/irq/generic-chip.c .shutdown = irq_gc_shutdown, virt/kvm/kvm_main.c .shutdown = kvm_shutdown, This has been tested by doing a kexec on x86_64 and aarch64.

Before: $ scripts/decode_stacktrace.sh vmlinux < kernel.log [17716.240635] Call trace: [17716.240646] skb_cow_data (??:?) [17716.240654] esp6_input (ld-temp.o:?)

However, doing so can break the decodecode routine as it will force the selection of other LLVM utilities down the line e.g. llvm-as.

2024-01-12kasan: avoid resetting aux_lockAndrey Konovalov1-2/+8
With commit 63b85ac56a64 ("kasan: stop leaking stack trace handles"), KASAN zeroes out alloc meta when an object is freed. The zeroed out data purposefully includes alloc and auxiliary stack traces but also accidentally includes aux_lock. As aux_lock is only initialized for each object slot during slab creation, when the freed slot is reallocated, saving auxiliary stack traces for the new object leads to lockdep reports when taking the zeroed out aux_lock. Arguably, we could reinitialize aux_lock when the object is reallocated, but a simpler solution is to avoid zeroing out aux_lock when an object gets freed.

2024-01-12lib/Kconfig.debug: disable CONFIG_DEBUG_INFO_BTF for HexagonNathan Chancellor1-0/+2
pahole, which generates BTF, relies on elfutils to process DWARF debug info. Because kernel modules are relocatable files, elfutils needs to resolve relocations when processing the DWARF .debug sections. Hexagon is not supported in binutils or elfutils, so elfutils is unable to process relocations in kernel modules, causing pahole to crash during BTF generation. Do not allow CONFIG_DEBUG_INFO_BTF to be selected for Hexagon until it is supported in elfutils, so that there are no more cryptic build failures during BTF generation.

2024-01-12kdump: defer the insertion of crashkernel resourcesHuacai Chen1-2/+12
In /proc/iomem, sub-regions should be inserted after their parent, otherwise the insertion of parent resource fails. But after generic crashkernel reservation applied, in both RISC-V and ARM64 (LoongArch will also use generic reservation later on), crashkernel resources are inserted before their parent, which causes the parent disappear in /proc/iomem. So we defer the insertion of crashkernel resources to an early_initcall(). 1, Without 'crashkernel' parameter: 100d0100-100d01ff : LOON0001:00 100d0100-100d01ff : LOON0001:00 LOON0001:00 100e0000-100e0bff : LOON0002:00 100e0000-100e0bff : LOON0002:00 LOON0002:00 1fe001e0-1fe001e7 : serial 90400000-fa17ffff : System RAM f6220000-f622ffff : Reserved f9ee0000-f9ee3fff : Reserved fa120000-fa17ffff : Reserved fa190000-fe0bffff : System RAM fa190000-fa1bffff : Reserved fe4e0000-47fffffff : System RAM 43c000000-441ffffff : Reserved 47ff98000-47ffa3fff : Reserved 47ffa4000-47ffa7fff : Reserved 47ffa8000-47ffabfff : Reserved 47ffac000-47ffaffff : Reserved 47ffb0000-47ffb3fff : Reserved 2, With 'crashkernel' parameter, before this patch: 100d0100-100d01ff : LOON0001:00 100d0100-100d01ff : LOON0001:00 LOON0001:00 100e0000-100e0bff : LOON0002:00 100e0000-100e0bff : LOON0002:00 LOON0002:00 1fe001e0-1fe001e7 : serial e6200000-f61fffff : Crash kernel fa190000-fe0bffff : System RAM fa190000-fa1bffff : Reserved fe4e0000-47fffffff : System RAM 43c000000-441ffffff : Reserved 47ff98000-47ffa3fff : Reserved 47ffa4000-47ffa7fff : Reserved 47ffa8000-47ffabfff : Reserved 47ffac000-47ffaffff : Reserved 47ffb0000-47ffb3fff : Reserved 3, With 'crashkernel' parameter, after this patch: 100d0100-100d01ff : LOON0001:00 100d0100-100d01ff : LOON0001:00 LOON0001:00 100e0000-100e0bff : LOON0002:00 100e0000-100e0bff : LOON0002:00 LOON0002:00 1fe001e0-1fe001e7 : serial 90400000-fa17ffff : System RAM e6200000-f61fffff : Crash kernel f6220000-f622ffff : Reserved f9ee0000-f9ee3fff : Reserved fa120000-fa17ffff : Reserved fa190000-fe0bffff : System RAM fa190000-fa1bffff : Reserved fe4e0000-47fffffff : System RAM 43c000000-441ffffff : Reserved 47ff98000-47ffa3fff : Reserved 47ffa4000-47ffa7fff : Reserved 47ffa8000-47ffabfff : Reserved 47ffac000-47ffaffff : Reserved 47ffb0000-47ffb3fff : Reserved Link: https://lkml.kernel.org/r/[email protected] Signed-off-by: Huacai Chen <[email protected]> Fixes: 0ab97169aa05 ("crash_core: add generic function to do reservation") Cc: Baoquan He <[email protected]> Cc: Zhen Lei <[email protected]> Cc: <[email protected]> [6.6+] Signed-off-by: Andrew Morton <[email protected]>

Some old devices are recognized to have legacy layout of configuration ROM. They have an inconvenience that FireWire subsystem adds no attributes for vendor information to corresponding devices. The main purpose of this update is to rectify the inconvenience. We have a slight concern about regression. The update changes the value of modalias for the unit devices by populating its model field, which was previously left as zero in the case. I've assessed the potential impact of this change and anticipate it to have minimal concern for both the kernel and user lands. The change is enough acceptable" * tag 'firewire-updates-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: firewire: core: fill model field in modalias of unit device for legacy layout of configuration ROM firewire: core: detect model name for legacy layout of configuration ROM firewire: core: detect numeric model identifier for legacy layout of configuration ROM firewire: test: add test of device attributes for legacy AV/C device firewire: test: add test of device attributes for simple AV/C device firewire: test: add KUnit test for device attributes firewire: core: replace magic number with macro firewire: core: adds constant qualifier for local helper functions firewire: make fw_bus_type const

Add to that some code shrink in the character device module and updates to DT bindings and that's pretty much it.

2024-01-12pwm: jz4740: Don't use dev_err_probe() in .request()Uwe Kleine-König1-3/+4
dev_err_probe() is only supposed to be used in probe functions. While it probably doesn't hurt, both the EPROBE_DEFER handling and calling device_set_deferred_probe_reason() are conceptually wrong in the request callback. So replace the call by dev_err() and a separate return statement. This effectively reverts commit c0bfe9606e03 ("pwm: jz4740: Simplify with dev_err_probe()").

2024-01-12ALSA: hda: Properly setup HDMI streamAmadeusz Sławiński1-0/+6
Since commit 4005d1ba0a7e ("ASoC: soc-dai: don't call PCM audio ops if the stream is not supported") HDMI playback is broken with avs driver. This happens because for HDMI stream (unlike generic HDA one) channels_min for stream is not set when creating PCMs. Fix this by setting the value based on first available converter.
