[PATCH v2] x86/hotplug: Silence APIC only after all irq's are migrated

by Ashok Raj

When offlining CPUs, fixup_irqs() migrates all interrupts away from the outgoing CPU to an online CPU. It's always possible the device sent an interrupt to the previous CPU destination. Pending interrupt bit in IRR in LAPIC identifies such interrupts. apic_soft_disable() will not capture any new interrupts in IRR. This causes interrupts from device to be lost during CPU offline. The issue was found when explicitly setting MSI affinity to a CPU and immediately offlining it. It was simple to recreate with a USB ethernet device and doing I/O to it while the CPU is offlined. Lost interrupts happen even when Interrupt Remapping is enabled. Current code does apic_soft_disable() before migrating interrupts. native_cpu_disable() { ... apic_soft_disable(); cpu_disable_common(); --> fixup_irqs(); // Too late to capture anything in IRR. } Just flipping the above call sequence seems to hit the IRR checks and the lost interrupt is fixed for both legacy MSI and when interrupt remapping is enabled.

Some pte bits from the existing mapping such as the soft-dirty and uffd write-protect bits are preserved by copying these to the temporary migration swap pte. However these bits are not stored at the same location for swap and non-swap ptes. Therefore testing these bits requires using the appropriate helper function for the given pte type. Unfortunately several code locations were found where the wrong helper function is being used to test soft_dirty and uffd_wp bits which leads to them getting incorrectly set or cleared during page-migration. Fix these by using the correct tests based on pte type.

This generally avoids the machinery involved in parsing format strings. `stpcpy` is just like `strcpy` except it returns the pointer to the new tail of `dest`. This optimization was introduced into clang-12. Implement this so that we don't observe linkage failures due to missing symbol definitions for `stpcpy`. Similar to last year's fire drill with: commit 5f074f3e192f ("lib/string.c: implement a basic bcmp") The kernel is somewhere between a "freestanding" environment (no full libc) and "hosted" environment (many symbols from libc exist with the same type, function signature, and semantics). As H. Peter Anvin notes, there's not really a great way to inform the compiler that you're targeting a freestanding environment but would like to opt-in to some libcall optimizations (see pr/47280 below), rather than opt-out. Arvind notes, -fno-builtin-* behaves slightly differently between GCC and Clang, and Clang is missing many __builtin_* definitions, which I consider a bug in Clang and am working on fixing. Masahiro summarizes the subtle distinction between compilers justly: To prevent transformation from foo() into bar(), there are two ways in Clang to do that; -fno-builtin-foo, and -fno-builtin-bar. There is only one in GCC; -fno-buitin-foo. (Any difference in that behavior in Clang is likely a bug from a missing __builtin_* definition.) Masahiro also notes: We want to disable optimization from foo() to bar(), but we may still benefit from the optimization from foo() into something else. If GCC implements the same transform, we would run into a problem because it is not -fno-builtin-bar, but -fno-builtin-foo that disables that optimization. In this regard, -fno-builtin-foo would be more future-proof than -fno-built-bar, but -fno-builtin-foo is still potentially overkill. We may want to prevent calls from foo() being optimized into calls to bar(), but we still may want other optimization on calls to foo(). It seems that compilers today don't quite provide the fine grain control over which libcall optimizations pseudo-freestanding environments would prefer. Finally, Kees notes that this interface is unsafe, so we should not encourage its use. As such, I've removed the declaration from any header, but it still needs to be exported to avoid linkage errors in modules.

[tip: irq/urgent] irqchip/stm32-exti: Avoid losing interrupts due to clearing pending bits by mistake

by tip-bot2 for qiuguorui1

The following commit has been merged into the irq/urgent branch of tip: Commit-ID: e579076ac0a3bebb440fab101aef3c42c9f4c709 Gitweb: https://git.kernel.org/tip/e579076ac0a3bebb440fab101aef3c42c9f4c709 Author: qiuguorui1 <qiuguorui1(a)huawei.com> AuthorDate: Thu, 20 Aug 2020 11:16:29 +08:00 Committer: Marc Zyngier <maz(a)kernel.org> CommitterDate: Tue, 25 Aug 2020 10:57:05 +01:00 irqchip/stm32-exti: Avoid losing interrupts due to clearing pending bits by mistake In the current code, when the eoi callback of the exti clears the pending bit of the current interrupt, it will first read the values of fpr and rpr, then logically OR the corresponding bit of the interrupt number, and finally write back to fpr and rpr. We found through experiments that if two exti interrupts, we call them int1/int2, arrive almost at the same time. in our scenario, the time difference is 30 microseconds, assuming int1 is triggered first. there will be an extreme scenario: both int's pending bit are set to 1, the irq handle of int1 is executed first, and eoi handle is then executed, at this moment, all pending bits are cleared, but the int 2 has not finally been reported to the cpu yet, which eventually lost int2. According to stm32's TRM description about rpr and fpr: Writing a 1 to this bit will trigger a rising edge event on event x, Writing 0 has no effect. Therefore, when clearing the pending bit, we only need to clear the pending bit of the irq.

[PATCH] Ignore UAS for JMicron JMS567 ATA/ATAPI Bridge

by Cyril Roelandt

This device does not support UAS properly and a similar entry already exists in drivers/usb/storage/unusual_uas.h. Without this patch, storage_probe() defers the handling of this device to UAS, which cannot handle it either.
