Recently I encountered one case where I cannot increase the MTU size directly from 1500 to a much bigger value with XDP enabled if the server is equipped with IXGBE card, which happened on thousands of servers in production environment. After applying the current patch, we can set the maximum MTU size to 3K. This patch follows the behavior of changing MTU as i40e/ice does.

2023-02-14spi: STIG Mode Fixes for spi-cadence-qspi driverMark Brown
Merge series from Dhruva Gole <d-gole@ti.com>: * Reset the CMD_CTRL Register, without which read/writes in STIG mode were failing in some cases. The issue came to light while using STIG Mode for small reads. * Also add a flag that can allow us to do direct reads but distinguish direct writes, thus enabling us to disable writes in DAC mode in some cases that require it. (Like to write to some connected Flash registers) * Fix register reads in STIG mode and also use STIG mode while reading flash registers. Currently if you try to read a register while in STIG mode there is no support for ADDR and thus naturally a register never gets read from the flash.

2023-02-15setlocalversion: use only the correct release tag for git-describeMasahiro Yamada
Currently, setlocalversion uses any annotated tag for git-describe. If we are at a tagged commit, it will not append the commit hash. $ git checkout v6.2-rc1^ $ make -s defconfig kernelrelease 6.1.0-14595-g292a089d78d3 $ git tag -a foo -m foo $ make -s kernelrelease 6.1.0 If a local tag 'foo' exists, it pretends to be a released version '6.1.0', while there are many commits on top of it. The output should be consistent irrespective of such a local tag. Pass the correct release tag to --match option of git-describe. In the mainline kernel, the SUBLEVEL is always '0', which is omitted from the tag. KERNELVERSION annotated tag 6.1.0 -> v6.1 (mainline) 6.2.0-rc5 -> v6.2-rc5 (mainline, release candidate) 6.1.7 -> v6.1.7 (stable) To preserve the behavior in linux-next, use the tag derived from localversion* files if exists. In linux-next, the local version is specified by the localversion-next file. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2023-02-14alpha: fix R_ALPHA_LITERAL reloc for large modulesEdward Humes
Previously, R_ALPHA_LITERAL relocations would overflow for large kernel modules. This was because the Alpha's apply_relocate_add was relying on the kernel's module loader to have sorted the GOT towards the very end of the module as it was mapped into memory in order to correctly assign the global pointer. While this behavior would mostly work fine for small kernel modules, this approach would overflow on kernel modules with large GOT's since the global pointer would be very far away from the GOT, and thus, certain entries would be out of range. This patch fixes this by instead using the Tru64 behavior of assigning the global pointer to be 32KB away from the start of the GOT. The change made in this patch won't work for multi-GOT kernel modules as it makes the assumption the module only has one GOT located at the beginning of .got, although for the vast majority kernel modules, this should be fine. Of the kernel modules that would previously result in a relocation error, none of them, even modules like nouveau, have even come close to filling up a single GOT, and they've all worked fine under this patch.

Pull kvm fixes from Paolo Bonzini: "Certain AMD processors are vulnerable to a cross-thread return address predictions bug. When running in SMT mode and one of the sibling threads transitions out of C0 state, the other thread gets access to twice as many entries in the RSB, but unfortunately the predictions of the now-halted logical processor are not purged. Therefore, the executing processor could speculatively execute from locations that the now-halted processor had trained the RSB on. The Spectre v2 mitigations cover the Linux kernel, as it fills the RSB when context switching to the idle thread. However, KVM allows a VMM to prevent exiting guest mode when transitioning out of C0 using the KVM_CAP_X86_DISABLE_EXITS capability can be used by a VMM to change this behavior. To mitigate the cross-thread return address predictions bug, a VMM must not be allowed to override the default behavior to intercept C0 transitions. These patches introduce a KVM module parameter that, if set, will prevent the user from disabling the HLT, MWAIT and CSTATE exits" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: Documentation/hw-vuln: Add documentation for Cross-Thread Return Predictions KVM: x86: Mitigate the cross-thread return address predictions bug x86/speculation: Identify processors vulnerable to SMT RSB predictions

The minidump table in the toc contains physical addresses that may lie before the physical address of the first elf segment in relocatable images. This change adds a custom dump function for minidumps which calculates the offset into the carveout region using the start of the physical address instead of the start of the first elf segment.

2023-02-14EDAC/amd64: Shut up an -Werror,-Wsometimes-uninitialized clang false positiveYazen Ghannam
Reportedly, clang cannot do interprocedural analysis: https://lore.kernel.org/r/20230213-amd64_edac-wsometimes-uninitialized-v1-1-5bde32b89e02@kernel.org and see that those arguments won't be used uninitialized. So, yeah, the code's fine even without this. Normally, such a "fix" won't be applied but that warning gets automatically enabled in -Wall builds and when CONFIG_WERROR is set in allmodconfig builds, the build fails. So shut it up with a minimal fix as this code will see more reorganization very soon.

2023-02-14rpmsg: glink: Cancel pending intent requests at removalBjorn Andersson
During removal of the glink edge interrupts are disabled and no more incoming messages are being serviced. In addition to the remote endpoint being defunct that means that any outstanding requests for intents will not be serviced, and qcom_glink_request_intent() will blindly wait for up to 10 seconds. Mark the intent request as not granted and complete the intent request completion to fail the waiting client immediately. Once the current intent request is failed, any potential clients waiting for the intent request mutex will not enter the same wait, as the qcom_glink_tx() call will fail fast.

2023-02-14rpmsg: glink: Fail qcom_glink_tx() once remove has been initiatedBjorn Andersson
Upon removing the glink edge, communication is at best one-way. This means that the very common scenario of glink requesting intents will not be possible to serve. Typically a successful transmission results in the client waiting for a response, with some timeout and a mechanism for aborting that timeout. Because of this, once the glink edge is defunct once removal is commenced it's better to fail transmissions fast.

2023-02-14rpmsg: glink: Move irq and mbox handling to transportsBjorn Andersson
Not all GLINK transports uses an interrupt and a mailbox instance. The interrupt for RPM needs to be IRQF_NOSUSPEND, while it seems reasonable for the SMEM interrupt to use irq_set_wake. The glink struct device is constructed in the SMEM and RPM drivers but torn down in the core driver. Move the interrupt and kick handling into the SMEM and RPM driver, to improve this and facilitate further improvements.
