2022-11-10Merge branch 'macsec-clear-encryption-keys-in-h-w-drivers'Paolo Abeni
Antoine Tenart says: ==================== macsec: clear encryption keys in h/w drivers Commit aaab73f8fba4 ("macsec: clear encryption keys from the stack after setting up offload") made sure to clean encryption keys from the stack after setting up offloading but some h/w drivers did a copy of the key which need to be zeroed as well. The MSCC PHY driver can actually be converted not to copy the encryption key at all, but such patch would be quite difficult to backport. I'll send a following up patch doing this in net-next once this series lands.

2022-11-09drm/amd/display: Fix reg timeout in enc314_enable_fifoNicholas Kazlauskas
[Why] The link enablement sequence can end up resetting the encoder while the PHY symclk isn't yet on. This means that waiting for symclk on will timeout, along with the reset bit never asserting high. This causes unnecessary delay when enabling the link and produces a warning affecting multiple IGT tests. [How] Don't wait for the symclk to be on here because firmware already does. Don't wait for reset if we know the symclk isn't on. Split the reset into a helper function that checks the bit and decides whether or not a delay is sufficient.

2022-11-09net/mlx5e: Fix usage of DMA sync APIMaxim Mikityanskiy
DMA sync functions should use the same direction that was used by DMA mapping. Use DMA_BIDIRECTIONAL for XDP_TX from regular RQ, which reuses the same mapping that was used for RX, and DMA_TO_DEVICE for XDP_TX from XSK RQ and XDP_REDIRECT, which establish a new mapping in this direction. On the RX side, use the same direction that was used when setting up the mapping (DMA_BIDIRECTIONAL for XDP, DMA_FROM_DEVICE otherwise). Also don't skip sync for device when establishing a DMA_FROM_DEVICE mapping for RX, as some architectures (ARM) may require invalidating caches before the device can use the mapping.

2022-11-09net/mlx5: Allow async trigger completion execution on single CPU systemsRoy Novich
For a single CPU system, the kernel thread executing mlx5_cmd_flush() never releases the CPU but calls down_trylock(&cmd→sem) in a busy loop. On a single processor system, this leads to a deadlock as the kernel thread which executes mlx5_cmd_invoke() never gets scheduled. Fix this, by adding the cond_resched() call to the loop, allow the command completion kernel thread to execute.

2022-11-09net/mlx5: Bridge, verify LAG state when adding bond to bridgeVlad Buslov
Mlx5 LAG is initialized asynchronously on a workqueue which means that for a brief moment after setting mlx5 UL representors as lower devices of a bond netdevice the LAG itself is not fully initialized in the driver. When adding such bond device to a bridge mlx5 bridge code will not consider it as offload-capable, skip creating necessary bookkeeping and fail any further bridge offload-related commands with it (setting VLANs, offloading FDBs, etc.). In order to make the error explicit during bridge initialization stage implement the code that detects such condition during NETDEV_PRECHANGEUPPER event and returns an error.

2022-11-09scripts/min-tool-version.sh: raise minimum clang version to 15.0.0 for s390Heiko Carstens
Before version 15.0.0 llvm's integrated assembler may silently generate corrupted code on s390. See e.g. commit e9953b729b78 ("s390/boot: workaround llvm IAS bug") for further details. While there have been workarounds applied for all known existing locations, there is nothing that prevents that new code with problematic patterns will be added. Therefore raise the minimum clang version to 15.0.0. Note that llvm commit e547b04d5b2c ("[SystemZ] Bugfix for symbolic displacements."), which is included in 15.0.0, fixes the broken code generation.

2022-11-09KVM: x86/pmu: Limit the maximum number of supported AMD GP countersLike Xu
The AMD PerfMonV2 specification allows for a maximum of 16 GP counters, but currently only 6 pairs of MSRs are accepted by KVM. While AMD64_NUM_COUNTERS_CORE is already equal to 6, increasing without adjusting msrs_to_save_all[] could result in out-of-bounds accesses. Therefore introduce a macro (named KVM_AMD_PMC_MAX_GENERIC) to refer to the number of counters supported by KVM.

2022-11-09KVM: x86/pmu: Limit the maximum number of supported Intel GP countersLike Xu
The Intel Architectural IA32_PMCx MSRs addresses range allows for a maximum of 8 GP counters, and KVM cannot address any more. Introduce a local macro (named KVM_INTEL_PMC_MAX_GENERIC) and use it consistently to refer to the number of counters supported by KVM, thus avoiding possible out-of-bound accesses.

2022-11-09KVM: x86/pmu: Do not speculatively query Intel GP PMCs that don't exist yetLike Xu
The SDM lists an architectural MSR IA32_CORE_CAPABILITIES (0xCF) that limits the theoretical maximum value of the Intel GP PMC MSRs allocated at 0xC1 to 14; likewise the Intel April 2022 SDM adds IA32_OVERCLOCKING_STATUS at 0x195 which limits the number of event selection MSRs to 15 (0x186-0x194). Limiting the maximum number of counters to 14 or 18 based on the currently allocated MSRs is clearly fragile, and it seems likely that Intel will even place PMCs 8-15 at a completely different range of MSR indices. So stop at the maximum number of GP PMCs supported today on Intel processors. There are some machines, like Intel P4 with non Architectural PMU, that may indeed have 18 counters, but those counters are in a completely different MSR address range and are not supported by KVM.

2022-11-09KVM: SVM: Only dump VMSA to klog at KERN_DEBUG levelPeter Gonda
Explicitly print the VMSA dump at KERN_DEBUG log level, KERN_CONT uses KERNEL_DEFAULT if the previous log line has a newline, i.e. if there's nothing to continuing, and as a result the VMSA gets dumped when it shouldn't. The KERN_CONT documentation says it defaults back to KERNL_DEFAULT if the previous log line has a newline. So switch from KERN_CONT to print_hex_dump_debug(). Jarkko pointed this out in reference to the original patch. See: https://lore.kernel.org/all/YuPMeWX4uuR1Tz3M@kernel.org/ print_hex_dump(KERN_DEBUG, ...) was pointed out there, but print_hex_dump_debug() should similar.
