2023-02-14dm: send just one event on resize, not twoMikulas Patocka
Device mapper sends an uevent when the device is suspended, using the function set_capacity_and_notify. However, this causes a race condition with udev. Udev skips scanning dm devices that are suspended. If we send an uevent while we are suspended, udev will be racing with device mapper resume code. If the device mapper resume code wins the race, udev will process the uevent after the device is resumed and it will properly scan the device. However, if udev wins the race, it will receive the uevent, find out that the dm device is suspended and skip scanning the device. This causes bugs such as systemd unmounting the device - see https://bugzilla.redhat.com/show_bug.cgi?id=2158628 This commit fixes this race. We replace the function set_capacity_and_notify with set_capacity, so that the uevent is not sent at this point. In do_resume, we detect if the capacity has changed and we pass a boolean variable need_resize_uevent to dm_kobject_uevent. dm_kobject_uevent adds "RESIZE=1" to the uevent if need_resize_uevent is set.

2023-02-14wifi: mac80211: fix off-by-one link settingJohannes Berg
The convention for find_first_bit() is 0-based, while ffs() is 1-based, so this is now off-by-one. I cannot reproduce the gcc-9 problem, but since the -1 is now removed, I'm hoping it will still avoid the original issue.

2023-02-14ixgbe: allow to increase MTU to 3K with XDP enabledJason Xing
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. This patch series has been tested on a TI AM625-SK-EVM with both a quad spi nor flash (s25hs) and OSPI NOR Flash (s28hs). Output of ltp-ddt test, "DD_RW_ERASESIZE_UBIFS" run with s25hs512t flash: ...

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
