git://git.kernel.org/pub/scm/linux/kernel/git/crng/random Pull more random number generator updates from Jason Donenfeld: "This time with some large scale treewide cleanups. The intent of this pull is to clean up the way callers fetch random integers. The current rules for doing this right are: - If you want a secure or an insecure random u64, use get_random_u64() - If you want a secure or an insecure random u32, use get_random_u32() The old function prandom_u32() has been deprecated for a while now and is just a wrapper around get_random_u32(). Same for get_random_int(). - If you want a secure or an insecure random u16, use get_random_u16() - If you want a secure or an insecure random u8, use get_random_u8() - If you want secure or insecure random bytes, use get_random_bytes(). The old function prandom_bytes() has been deprecated for a while now and has long been a wrapper around get_random_bytes() - If you want a non-uniform random u32, u16, or u8 bounded by a certain open interval maximum, use prandom_u32_max() I say "non-uniform", because it doesn't do any rejection sampling or divisions. Hence, it stays within the prandom_*() namespace, not the get_random_*() namespace. I'm currently investigating a "uniform" function for 6.2. We'll see what comes of that. By applying these rules uniformly, we get several benefits: - By using prandom_u32_max() with an upper-bound that the compiler can prove at compile-time is ≤65536 or ≤256, internally get_random_u16() or get_random_u8() is used, which wastes fewer batched random bytes, and hence has higher throughput. - By using prandom_u32_max() instead of %, when the upper-bound is not a constant, division is still avoided, because prandom_u32_max() uses a faster multiplication-based trick instead. - By using get_random_u16() or get_random_u8() in cases where the return value is intended to indeed be a u16 or a u8, we waste fewer batched random bytes, and hence have higher throughput. This series was originally done by hand while I was on an airplane without Internet. Later, Kees and I worked on retroactively figuring out what could be done with Coccinelle and what had to be done manually, and then we split things up based on that. So while this touches a lot of files, the actual amount of code that's hand fiddled is comfortably small" * tag 'random-6.1-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: prandom: remove unused functions treewide: use get_random_bytes() when possible treewide: use get_random_u32() when possible treewide: use get_random_{u8,u16}() when possible, part 2 treewide: use get_random_{u8,u16}() when possible, part 1 treewide: use prandom_u32_max() when possible, part 2 treewide: use prandom_u32_max() when possible, part 1

2022-10-13Merge patch series "Fix dt-validate issues on qemu dtbdumps due to dt-bindings"Palmer Dabbelt3-9/+19
Conor Dooley <mail@conchuod.ie> says: From: Conor Dooley <conor.dooley@microchip.com> The device trees produced automatically for the virt and spike machines fail dt-validate on several grounds. Some of these need to be fixed in the linux kernel's dt-bindings, but others are caused by bugs in QEMU. Patches been sent that fix the QEMU issues [0], but a couple of them need to be fixed in the kernel's dt-bindings. The first patches add compatibles for "riscv,{clint,plic}0" which are present in drivers and the auto generated QEMU dtbs. Thanks to Rob Herring for reporting these issues [1], Conor. To reproduce the errors: ./build/qemu-system-riscv64 -nographic -machine virt,dumpdtb=qemu.dtb dt-validate -p /path/to/linux/kernel/Documentation/devicetree/bindings/processed-schema.json qemu.dtb (The processed schema needs to be generated first) 0 - https://lore.kernel.org/linux-riscv/20220810184612.157317-1-mail@conchuod.ie/ 1 - https://lore.kernel.org/linux-riscv/20220803170552.GA2250266-robh@kernel.org/ * fix-dt-validate: dt-bindings: riscv: add new riscv,isa strings for emulators dt-bindings: interrupt-controller: sifive,plic: add legacy riscv compatible dt-bindings: timer: sifive,clint: add legacy riscv compatible Link: https://lore.kernel.org/r/20220823183319.3314940-1-mail@conchuod.ie [Palmer: some cover letter pruning, and dropped #4 as suggested.] Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
2022-10-13dt-bindings: riscv: add new riscv,isa strings for emulatorsConor Dooley1-3/+2
The QEMU virt and spike machines currently export a riscv,isa string of "rv64imafdcsuh", While the RISC-V foundation has been ratifying a bunch of extenstions etc, the kernel has remained relatively static with what hardware is supported - but the same is not true of QEMU. Using the virt machine and running dt-validate on the dumped dtb fails, partly due to the unexpected isa string. Rather than enumerate the many many possbilities, change the pattern to a regex, with the following assumptions: - ima are required - the single letter order is fixed & we don't care about things that can't even do "ima" - the standard multi letter extensions are all in a "_z<foo>" format where the first letter of <foo> is a valid single letter extension - _s & _h are used for supervisor and hyper visor extensions - convention says that after the first two chars, a standard multi letter extension name could be an english word (ifencei anyone?) so it's not worth restricting the charset - as the above is just convention, don't apply any charset restrictions to reduce future churn - vendor ISA extensions begind with _x and have no charset restrictions - we don't care about an e extension from an OS pov - that attempting to validate the contents of the multiletter extensions with dt-validate beyond the formatting is a futile, massively verbose or unwieldy exercise at best The following limitations also apply: - multi letter extension ordering is not enforced. dt-schema does not appear to allow for named match groups, so the resulting regex would be even more of a headache - ditto for the numbered extensions Finally, add me as a maintainer of the binding so that when it breaks in the future, I can be held responsible!

Since the Linux uABI was already frozen at that point it's just been demoted to part of the uABI, but that was never written down.

The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.

git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci Pull pci updates from Bjorn Helgaas: "Resource management: - Distribute spare resources to unconfigured hotplug bridges at boot-time (not just when hot-adding such a bridge), which makes hot-adding devices to docks work better. - Revert to a BAR assignment inherited from firmware only when the address is actually reachable via any upstream bridges, which fixes some cases where firmware doesn't configure all devices. - Add a sysfs interface to resize BARs so this can be done before assigning devices to a VM through VFIO. Power management: - Disable Precision Time Management for all devices on suspend to enable lower-power PM state. We previously did this just for Root Ports, which isn't enough because downstream devices can still generate PTM messages, which cause errors if it's disabled in the Root Port. - Save and restore the ASPM L1 PM Substates configuration for suspend/ resume. Previously this configuration was lost, so L1.x states likely stopped working after resume. - Check whether the L1 PM Substates Capability exists. If it didn't exist, we previously read junk and tried to configure L1 Substates based on that. - Fix the LTR_L1.2_THRESHOLD computation, which previously set a threshold for entering L1.2 that was too low in some cases. - Reduce the delay after transitions to or from D3cold by using usleep_range() rather than msleep(), which often slept for ~19ms instead of the 10ms normally required. The spec says 10ms is enough, but it's possible we could trip over devices that need a little more. Error handling: - Work around a BIOS bug that caused Intel Root Ports to advertise a Root Port Programmed I/O (RP PIO) log size of zero, which caused annoying warnings and prevented the kernel from dumping log registers for DPC errors. Qualcomm PCIe controller driver: - Add support for SC8280XP and SA8540P host controllers and SM8450 endpoint controller. - Disable Master AXI clock on endpoint controllers to save power when link is idle or in L1.x. - Expose link state transition counts via debugfs to help debug issues with low-power states. - Add auto-loading module support.

They've been under test in linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam Howlett. An overlapping range-based tree for vmas. It it apparently slightly more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat at [1]. This has yet to be addressed due to Liam's unfortunately timed vacation. He is now back and we'll get this fixed up. - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses clang-generated instrumentation to detect used-unintialized bugs down to the single bit level. KMSAN keeps finding bugs.

Minor changes: - Added Mark Rutland as FTRACE reviewer - Updated user_events to make it on its way to remove the BROKEN tag. The changes should now be acceptable but will run it through a cycle and hopefully we can remove the BROKEN tag next release. - Added filtering to eprobes - Added a delta time to the benchmark trace event - Have the histogram and filter callbacks called via a switch statement instead of indirect functions.

A reader may block when the ring buffer is disabled, but if it was blocked when the ring buffer is disabled it should then wake up. Fixes: - Allow splice to read partially read ring buffer pages.
