2020-08-28netfilter: nfnetlink: nfnetlink_unicast() reports EAGAIN instead of ENOBUFSPablo Neira Ayuso5-40/+40
Frontend callback reports EAGAIN to nfnetlink to retry a command, this is used to signal that module autoloading is required. Unfortunately, nlmsg_unicast() reports EAGAIN in case the receiver socket buffer gets full, so it enters a busy-loop. This patch updates nfnetlink_unicast() to turn EAGAIN into ENOBUFS and to use nlmsg_unicast(). Remove the flags field in nfnetlink_unicast() since this is always MSG_DONTWAIT in the existing code which is exactly what nlmsg_unicast() passes to netlink_unicast() as parameter.

2020-08-28KVM: arm64: Set HCR_EL2.PTW to prevent AT taking synchronous exceptionJames Morse1-1/+2
AT instructions do a translation table walk and return the result, or the fault in PAR_EL1. KVM uses these to find the IPA when the value is not provided by the CPU in HPFAR_EL1. If a translation table walk causes an external abort it is taken as an exception, even if it was due to an AT instruction. (DDI0487F.a's D5.2.11 "Synchronous faults generated by address translation instructions") While we previously made KVM resilient to exceptions taken due to AT instructions, the device access causes mismatched attributes, and may occur speculatively. Prevent this, by forbidding a walk through memory described as device at stage2. Now such AT instructions will report a stage2 fault. Such a fault will cause KVM to restart the guest. If the AT instructions always walk the page tables, but guest execution uses the translation cached in the TLB, the guest can't make forward progress until the TLB entry is evicted. This isn't a problem, as since commit 5dcd0fdbb492 ("KVM: arm64: Defer guest entry when an asynchronous exception is pending"), KVM will return to the host to process IRQs allowing the rest of the system to keep running.

2020-08-28KVM: arm64: Survive synchronous exceptions caused by AT instructionsJames Morse3-8/+42
KVM doesn't expect any synchronous exceptions when executing, any such exception leads to a panic(). AT instructions access the guest page tables, and can cause a synchronous external abort to be taken. The arm-arm is unclear on what should happen if the guest has configured the hardware update of the access-flag, and a memory type in TCR_EL1 that does not support atomic operations. B2.2.6 "Possible implementation restrictions on using atomic instructions" from DDI0487F.a lists synchronous external abort as a possible behaviour of atomic instructions that target memory that isn't writeback cacheable, but the page table walker may behave differently. Make KVM robust to synchronous exceptions caused by AT instructions. Add a get_user() style helper for AT instructions that returns -EFAULT if an exception was generated. While KVM's version of the exception table mixes synchronous and asynchronous exceptions, only one of these can occur at each location. Re-enter the guest when the AT instructions take an exception on the assumption the guest will take the same exception. This isn't guaranteed to make forward progress, as the AT instructions may always walk the page tables, but guest execution may use the translation cached in the TLB. This isn't a problem, as since commit 5dcd0fdbb492 ("KVM: arm64: Defer guest entry when an asynchronous exception is pending"), KVM will return to the host to process IRQs allowing the rest of the system to keep running.

2020-08-28KVM: arm64: Add kvm_extable for vaxorcism codeJames Morse8-26/+108
KVM has a one instruction window where it will allow an SError exception to be consumed by the hypervisor without treating it as a hypervisor bug. This is used to consume asynchronous external abort that were caused by the guest. As we are about to add another location that survives unexpected exceptions, generalise this code to make it behave like the host's extable. KVM's version has to be mapped to EL2 to be accessible on nVHE systems. The SError vaxorcism code is a one instruction window, so has two entries in the extable. Because the KVM code is copied for VHE and nVHE, we end up with four entries, half of which correspond with code that isn't mapped.

2020-08-28arm64: tegra: Add missing timeout clock to Tegra186 SDMMC nodesSowjanya Komatineni1-8/+12
commit 39cb62cb8973 ("arm64: tegra: Add Tegra186 support") Tegra186 uses separate SDMMC_LEGACY_TM clock for data timeout and this clock is not enabled currently which is not recommended. Tegra186 SDMMC advertises 12Mhz as timeout clock frequency in host capability register and uses it by default. So, this clock should be kept enabled by the SDMMC driver.

commit b5a84ecf025a ("mmc: tegra: Add Tegra210 support") Tegra210 and later uses separate SDMMC_LEGACY_TM clock for data timeout.

commit 4346b7c7941d ("mmc: tegra: Add Tegra186 support") SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK is set for Tegra186 from the beginning of its support in driver. Tegra186 SDMMC hardware by default uses timeout clock (TMCLK) instead of SDCLK and this quirk should not be set. So, this patch remove this quirk for Tegra186.

2020-08-27md/raid5: make sure stripe_size as power of twoYufen Yu1-2/+5
Commit 3b5408b98e4d ("md/raid5: support config stripe_size by sysfs entry") make stripe_size as a configurable value. It just requires stripe_size as multiple of 4KB. In fact, we should make sure stripe_size as power of two. Otherwise, stripe_shift which is the result of ilog2 can not represent the real stripe_size. Then, stripe_hash() and stripe_hash_locks_hash() may get unexpected value.
