If there is a stuck irq that the handler doesn't address, returning IRQ_HANDLED unconditionally makes it impossible for the irq core to detect the problem and disable the irq. So only return IRQ_HANDLED if an event was handled. A stuck irq is still problematic, but with this change at least it only makes the UART nonfunctional instead of occupying the (usually only) CPU by 100% and so stall the whole machine.

We are seeing start_tx being called after port shutdown as noted by Jiri. This happens because we are missing the startup and shutdown related functions for the serial base port. Let's fix the issue by adding startup and shutdown functions for the serial base port to block tx flushing for the serial base port when the port is not in use.

The circular buffer is NULLified in uart_tty_port_shutdown() under the spin lock. However, the PM or other timer based callbacks may still trigger after this event without knowning that buffer pointer is not valid. Since the serial code is a bit inconsistent in checking the buffer state (some rely on the head-tail positions, some on the buffer pointer), it's better to have both aligned, i.e. buffer pointer to be NULL and head-tail possitions to be the same, meaning it's empty. This will prevent asynchronous calls to dereference NULL pointer as reported recently in 8250 case: BUG: kernel NULL pointer dereference, address: 00000cf5 Workqueue: pm pm_runtime_work EIP: serial8250_tx_chars (drivers/tty/serial/8250/8250_port.c:1809) ... ? serial8250_tx_chars (drivers/tty/serial/8250/8250_port.c:1809) __start_tx (drivers/tty/serial/8250/8250_port.c:1551) serial8250_start_tx (drivers/tty/serial/8250/8250_port.c:1654) serial_port_runtime_suspend (include/linux/serial_core.h:667 drivers/tty/serial/serial_port.c:63) __rpm_callback (drivers/base/power/runtime.c:393) ? serial_port_remove (drivers/tty/serial/serial_port.c:50) rpm_suspend (drivers/base/power/runtime.c:447) The proposed change will prevent ->start_tx() to be called during suspend on shut down port.

The mitigation was intended to stop the irq completely. That may be better than a hard lock-up but it turns out that you get a crash anyway if you're using pmac_zilog as a serial console: ttyPZ0: pmz: rx irq flood ! BUG: spinlock recursion on CPU#0, swapper/0 That's because the pr_err() call in pmz_receive_chars() results in pmz_console_write() attempting to lock a spinlock already locked in pmz_interrupt(). With CONFIG_DEBUG_SPINLOCK=y, this produces a fatal BUG splat. The spinlock in question is the one in struct uart_port. Even when it's not fatal, the serial port rx function ceases to work. Also, the iteration limit doesn't play nicely with QEMU, as can be seen in the bug report linked below. A web search for other reports of the error message "pmz: rx irq flood" didn't produce anything. So I don't think this code is needed any more. Remove it.

Adam Goldman authored
In the FireWire OHCI interrupt handler, if a bus reset interrupt has occurred, mask bus reset interrupts until bus_reset_work has serviced and cleared the interrupt. Normally, we always leave bus reset interrupts masked. We infer the bus reset from the self-ID interrupt that happens shortly thereafter. A scenario where we unmask bus reset interrupts was introduced in 2008 in a007bb85: If OHCI_PARAM_DEBUG_BUSRESETS (8) is set in the debug parameter bitmask, we will unmask bus reset interrupts so we can log them. irq_handler logs the bus reset interrupt. However, we can't clear the bus reset event flag in irq_handler, because we won't service the event until later. irq_handler exits with the event flag still set. If the corresponding interrupt is still unmasked, the first bus reset will usually freeze the system due to irq_handler being called again each time it exits. This freeze can be reproduced by loading firewire_ohci with "modprobe firewire_ohci debug=-1" (to enable all debugging output). Apparently there are also some cases where bus_reset_work will get called soon enough to clear the event, and operation will continue normally. This freeze was first reported a few months after a007bb85 was committed, but until now it was never fixed. The debug level could safely be set to -1 through sysfs after the module was loaded, but this would be ineffectual in logging bus reset interrupts since they were only unmasked during initialization. irq_handler will now leave the event flag set but mask bus reset interrupts, so irq_handler won't be called again and there will be no freeze. If OHCI_PARAM_DEBUG_BUSRESETS is enabled, bus_reset_work will unmask the interrupt after servicing the event, so future interrupts will be caught as desired. As a side effect to this change, OHCI_PARAM_DEBUG_BUSRESETS can now be enabled through sysfs in addition to during initial module loading. However, when enabled through sysfs, logging of bus reset interrupts will be effective only starting with the second bus reset, after bus_reset_work has executed. Signed-off-by:

Pull arm64 fix from Catalin Marinas: "arm64/ptrace fix to use the correct SVE layout based on the saved floating point state rather than the TIF_SVE flag. The latter may be left on during syscalls even if the SVE state is discarded" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64/ptrace: Use saved floating point state type to determine SVE layout

Pull RISC-V fixes from Palmer Dabbelt: - A fix for an __{get,put}_kernel_nofault to avoid an uninitialized value causing spurious failures - compat_vdso.so.dbg is now installed to the standard install location - A fix to avoid initializing PERF_SAMPLE_BRANCH_*-related events, as they aren't supported and will just later fail - A fix to make AT_VECTOR_SIZE_ARCH correct now that we're providing AT_MINSIGSTKSZ - pgprot_nx() is now implemented, which fixes vmap W^X protection - A fix for the vector save/restore code, which at least manifests as corrupted vector state when a signal is taken - A fix for a race condition in instruction patching - A fix to avoid leaking the kernel-mode GP to userspace, which is a kernel pointer leak that can be used to defeat KASLR in various ways - A handful of smaller fixes to build warnings, an overzealous printk, and some missing tracing annotations * tag 'riscv-for-linus-6.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: process: Fix kernel gp leakage riscv: Disable preemption when using patch_map() riscv: Fix warning by declaring arch_cpu_idle() as noinstr riscv: use KERN_INFO in do_trap riscv: Fix vector state restore in rt_sigreturn() riscv: mm: implement pgprot_nx riscv: compat_vdso: align VDSOAS build log RISC-V: Update AT_VECTOR_SIZE_ARCH for new AT_MINSIGSTKSZ riscv: Mark __se_sys_* functions __used drivers/perf: riscv: Disable PERF_SAMPLE_BRANCH_* while not supported riscv: compat_vdso: install compat_vdso.so.dbg to /lib/modules/*/vdso/ riscv: hwprobe: do not produce frtace relocation riscv: Fix spurious errors from __get/put_kernel_nofault riscv: mm: Fix prototype to avoid discarding const

Pull thermal control fixes from Rafael Wysocki: "These fix two power allocator thermal governor issues and an ACPI thermal driver regression that all were introduced during the 6.8 development cycle. Specifics: - Allow the power allocator thermal governor to bind to a thermal zone without cooling devices and/or without trip points (Nikita Travkin) - Make the ACPI thermal driver register a tripless thermal zone when it cannot find any usable trip points instead of returning an error from acpi_thermal_add() (Stephen Horvath)" * tag 'thermal-6.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: thermal: gov_power_allocator: Allow binding without trip points thermal: gov_power_allocator: Allow binding without cooling devices ACPI: thermal: Register thermal zones without valid trip points
