2022-03-22Revert "random: block in /dev/urandom"Linus Torvalds2-18/+56
This reverts commit 6f98a4bfee72c22f50aedb39fb761567969865fe. It turns out we still can't do this. Way too many platforms that don't have any real source of randomness at boot and no jitter entropy because they don't even have a cycle counter. As reported by Guenter Roeck: "This causes a large number of qemu boot test failures for various architectures (arm, m68k, microblaze, sparc32, xtensa are the ones I observed). Common denominator is that boot hangs at 'Saving random seed:'" This isn't hugely unexpected - we tried it, it failed, so now we'll revert it.

2022-03-21net: mdio: mscc-miim: add lan966x internal phy reset supportMichael Walle1-18/+49
The LAN966x has two internal PHYs which are in reset by default. The driver already supported the internal PHYs of the SparX-5. Now add support for the LAN966x, too. Add a new compatible to distinguish them. The LAN966x has additional control bits in this register, thus convert the regmap_write() to regmap_update_bits() to leave the remaining bits untouched. This doesn't change anything for the SparX-5 SoC, because there, the register consists only of reset bits.

2022-03-21net: dsa: mv88e6xxx: Fill in STU support for all supported chipsTobias Waldekranz1-0/+48
Some chips using the split VTU/STU design will not accept VTU entries who's SID points to an invalid STU entry. Therefore, mark all those chips with either the mv88e6352_g1_stu_* or mv88e6390_g1_stu_* ops as appropriate. Notably, chips for the Opal Plus (6085/6097) era seem to use a different implementation than those from Agate (6352) and onwards, even though their external interface is the same. The former happily accepts VTU entries referencing invalid STU entries, while the latter does not. This fixes an issue where the driver would fail to probe switch trees that contained chips of the Agate/Topaz generation which did not declare STU support, as loaded VTU entries would be read back as invalid.

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random Pull random number generator updates from Jason Donenfeld: "There have been a few important changes to the RNG's crypto, but the intent for 5.18 has been to shore up the existing design as much as possible with modern cryptographic functions and proven constructions, rather than actually changing up anything fundamental to the RNG's design. So it's still the same old RNG at its core as before: it still counts entropy bits, and collects from the various sources with the same heuristics as before, and so forth. However, the cryptographic algorithms that transform that entropic data into safe random numbers have been modernized. Just as important, if not more, is that the code has been cleaned up and re-documented. As one of the first drivers in Linux, going back to 1.3.30, its general style and organization was showing its age and becoming both a maintenance burden and an auditability impediment. Hopefully this provides a more solid foundation to build on for the future. I encourage you to open up the file in full, and maybe you'll remark, "oh, that's what it's doing," and enjoy reading it. That, at least, is the eventual goal, which this pull begins working toward. Here's a summary of the various patches in this pull: - /dev/urandom and /dev/random now do the same thing, per the patch we discussed on the list. I think this is worth trying out. If it does appear problematic, I've made sure to keep it standalone and revertible without any conflicts. - Fixes and cleanups for numerous integer type problems, locking issues, and general code quality concerns. - The input pool's LFSR has been replaced with a cryptographically secure hash function, which has security and performance benefits alike, and consequently allows us to count entropy bits linearly. - The pre-init injection now uses a real hash function too, instead of an LFSR or vanilla xor. - The interrupt handler's fast_mix() function now uses one round of SipHash, rather than the fake crypto that was there before. - All additions of RDRAND and RDSEED now go through the input pool's hash function, in part to mitigate ridiculous hypothetical CPU backdoors, but more so to have a consistent interface for ingesting entropy that's easy to analyze, making everything happen one way, instead of a potpourri of different ways. - The crng now works on per-cpu data, while also being in accordance with the actual "fast key erasure RNG" design. This allows us to fix several boot-time race complications associated with the prior dynamically allocated model, eliminates much locking, and makes our backtrack protection more robust. - Batched entropy now erases doled out values so that it's backtrack resistant. - Working closely with Sebastian, the interrupt handler no longer needs to take any locks at all, as we punt the synchronized/expensive operations to a workqueue. This is especially nice for PREEMPT_RT, where taking spinlocks in irq context is problematic. It also makes the handler faster for the rest of us. - Also working with Sebastian, we now do the right thing on CPU hotplug, so that we don't use stale entropy or fail to accumulate new entropy when CPUs come back online. - We handle virtual machines that fork / clone / snapshot, using the "vmgenid" ACPI specification for retrieving a unique new RNG seed, which we can use to also make WireGuard (and in the future, other things) safe across VM forks. - Around boot time, we now try to reseed more often if enough entropy is available, before settling on the usual 5 minute schedule. - Last, but certainly not least, the documentation in the file has been updated considerably" * tag 'random-5.18-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: (60 commits) random: check for signal and try earlier when generating entropy random: reseed more often immediately after booting random: make consistent usage of crng_ready() random: use SipHash as interrupt entropy accumulator wireguard: device: clear keys on VM fork random: provide notifier for VM fork random: replace custom notifier chain with standard one random: do not export add_vmfork_randomness() unless needed virt: vmgenid: notify RNG of VM fork and supply generation ID ACPI: allow longer device IDs random: add mechanism for VM forks to reinitialize crng random: don't let 644 read-only sysctls be written to random: give sysctl_random_min_urandom_seed a more sensible value random: block in /dev/urandom random: do crng pre-init loading in worker rather than irq random: unify cycles_t and jiffies usage and types random: cleanup UUID handling random: only wake up writers after zap if threshold was passed random: round-robin registers as ulong, not u32 random: clear fast pool, crng, and batches in cpuhp bring up ...

This itself seems a bit sketchy, but the real problem with GCC12 is that it is moving the actual reads/writes around at will as though they were independent operations when in truth they are not, but the compiler can't know that. When looking at the assembly dumps for many of these routines its possible to see very clean, but not strictly in program order operations occurring as the compiler would be free to do if these weren't actually register reads/write operations. Its possible to suppress the timeout with a liberal bit of dma_mb()'s sprinkled around but the device still seems unable to reliably send/receive data. A better plan is to use the safer readl/writel everywhere. Since this partially reverts an older commit, which notes the use of the relaxed variants for performance reasons. I would suggest that any performance problems with this commit are targeted at relaxing only the performance critical code paths after assuring proper barriers.

2022-03-21PCI: Avoid broken MSI on SB600 USB devicesBjorn Helgaas1-0/+12
Some ATI SB600 USB adapters advertise MSI, but if INTx is disabled by setting PCI_COMMAND_INTX_DISABLE, MSI doesn't work either. The PCI/PCIe specs do not require software to set PCI_COMMAND_INTX_DISABLE when enabling MSI, but Linux has done that for many years. Mick reported that 306c54d0edb6 ("usb: hcd: Try MSI interrupts on PCI devices") broke these devices. Prior to 306c54d0edb6, they used INTx. Starting with 306c54d0edb6, they use MSI, and and the fact that Linux sets PCI_COMMAND_INTX_DISABLE means both INTx and MSI are disabled on these devices. Avoid this SB600 defect by disabling MSI so we use INTx as before.
