cherry-pick improved erratum 1386 workaround

The original fix disabled the xsaves feature for zen1/2. The issue has
since been fixed in the cpus microcode and this patch keeps the feature enabled
if the microcode version is recent enough to contain the fix.
The patch had to be altered slightly to apply cleanly on 6.5, but no
changes content-wise.

+BUILD
+=====
+
+As this is packaging for the Linux kernel with some extra integrations, like
+ZFS, this repo cannot be handled like a plain Linux kernel git repository.
+
+The actual Linux kernel source lives in a git submodule.
+
+For a build you should init the submodules and then handle it like most our
+Debian packaging builds. If unsure you can follow this:
+
+Installing Build-Dependencies
+-----------------------------
+
+You can either just check the package metadata template `debian/control.in`
+and install the packages listed in the `Build-Depends` section manually
+(replace `debhelper-compat` with just `debhelper`) or use a more automated way
+described below:
+
+ # install base build-dependencies and helpers
+ apt update
+ apt install devscripts
+
+ # create build-directory so that we got final packaging control files from the
+ # .in templates generated
+ make build-dir-fresh
+
+ # install build-dependencies (replace BUILD-DIR with actual one)
+ mk-build-deps -ir BUILD-DIR/debian/control
+
+
+Package Build
+-------------
+
+ # start the actual build
+ make deb
+
+For simple KConfig modifications you can adapt the list in `debian/rules` file.
+For quick code changes to the actual kernel code you can do them directly in
+the submodule/ubuntu-kernels directory, then re-create the build-directory, e.g.:
+
+ make clean
+ # now build again, explicitly creating the build-dir isn't required anymore
+ # after one has the build-dependencies already installed.
+ make deb
+
+
+Modify-Build-Test Cycles
+------------------------
+
+Ideally you avoid the need for doing a full package build and just directly
+build linux from the ubuntu-kernels or the mainline (stable) repo with copying
+over a build-config of a proxmox-kernel to that as .config and then using the
+`make olddefconfig` target.
+
+If you need full package builds you can try to make changes inside the
+BUILD-DIR directly and then continue build from there, e.g., using
+`dpkg-buildpackage -b -uc -us --no-pre-clean`. Depending on what stage you want
+to continue build you might need to touch, or remove some *.prepared files.
+Just check `debian/rules` for how kernel build progress is tracked by make.

-Built-in graphics on HP EliteDesk 805 G6 doesn't work because graphics

-  pci 0000:00:08.1: [mem 0x10030000000-0x100401fffff 64bit pref] clipped to [mem 0x10030000000-0x100303fffff 64bit pref]
-  pci 0000:00:08.1:   bridge window [mem 0x10030000000-0x100303fffff 64bit pref]

-  pci 0000:07:00.0: can't claim BAR 2 [mem 0x10040000000-0x100401fffff 64bit pref]: no compatible bridge window
-
-However, the root bus has two contiguous apertures that can contain the
-child resource requested.
-
-Coalesce contiguous apertures so we can allocate from the entire contiguous
-region.
-
-This is the second take of commit 65db04053efe ("PCI: Coalesce host
-bridge contiguous apertures"). The original approach sorts the apertures
-by address, but that makes NVMe stop working on QEMU ppc:sam460ex:
-  PCI host bridge to bus 0002:00
-  pci_bus 0002:00: root bus resource [io  0x0000-0xffff]
-  pci_bus 0002:00: root bus resource [mem 0xd80000000-0xdffffffff] (bus address [0x80000000-0xffffffff])
-  pci_bus 0002:00: root bus resource [mem 0xc0ee00000-0xc0eefffff] (bus address [0x00000000-0x000fffff])
-
-After the offending commit:
-  PCI host bridge to bus 0002:00
-  pci_bus 0002:00: root bus resource [io  0x0000-0xffff]
-  pci_bus 0002:00: root bus resource [mem 0xc0ee00000-0xc0eefffff] (bus address [0x00000000-0x000fffff])
-  pci_bus 0002:00: root bus resource [mem 0xd80000000-0xdffffffff] (bus address [0x80000000-0xffffffff])
-
-Since the apertures on HP EliteDesk 805 G6 are already in ascending
-order, doing a precautious sorting is not necessary.
-
-Remove the sorting part to avoid the regression on ppc:sam460ex.

-Subject: [PATCH] io-wq: split bounded and unbounded work into separate lists
-
-We've got a few issues that all boil down to the fact that we have one
-list of pending work items, yet two different types of workers to
-serve them. This causes some oddities around workers switching type and
-even hashed work vs regular work on the same bounded list.
-
-Just separate them out cleanly, similarly to how we already do
-accounting of what is running. That provides a clean separation and
-removes some corner cases that can cause stalls when handling IO
-that is punted to io-wq.

+From: Thomas Lamprecht <t.lamprecht@proxmox.com>
+Date: Fri, 14 Jul 2023 18:10:32 +0200
+Subject: [PATCH] kvm: xsave set: mask-out PKRU bit in xfeatures if vCPU has no
+ support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Fixes live-migrations & snapshot-rollback of VMs with a restricted
+CPU type (e.g., qemu64) from our 5.15 based kernel (default Proxmox
+VE 7.4) to the 6.2 (and future newer) of Proxmox VE 8.0.
+
+Previous to ad856280ddea ("x86/kvm/fpu: Limit guest user_xfeatures to
+supported bits of XCR0") the PKRU bit of the host could leak into the
+state from the guest, which caused trouble when migrating between
+hosts with different CPUs, i.e., where the source supported it but
+the target did not, causing a general protection fault when the guest
+tried to use a pkru related instruction after the migration.
+
+But the fix, while welcome, caused a temporary out-of-sync state when
+migrating such a VM from a kernel without the fix to a kernel with
+the fix, as it threw of KVM when the CPUID of the guest and most of
+the state doesn't report XSAVE and thus any xfeatures, but PKRU and
+the related state is set as enabled, causing the vCPU to spin at 100%
+without any progress forever.
+
+The fix could be at two sites, either in QEMU or in the kernel, I
+choose the kernel as we have all the info there for a targeted
+heuristic so that we don't have to adapt QEMU and qemu-server, the
+latter even on both sides.
+
+Still, a short summary of the possible fixes and short drawbacks:
+* on QEMU-side either
+  - clear the PKRU state in the migration saved state would be rather
+    complicated to implement as the vCPU is initialised way before we
+    have the saved xfeature state available to check what we'd need
+    to do, plus the user-space only gets a memory blob from ioctl
+    KVM_GET_XSAVE2 that it passes to KVM_SET_XSAVE ioctl, there are
+    no ABI guarantees, and while the struct seem stable for 5.15 to
+    6.5-rc1, that doesn't has to be for future kernels, so off the
+    table.
+  - enforce that the CPUID reports PKU support even if it normally
+    wouldn't. While this works (tested by hard-coding it as POC) it
+    is a) not really nice and b) needs some interaction from
+    qemu-server to enable this flag as otherwise we have no good info
+    to decide when it's OK to do this, which means we need to adapt
+    both PVE 7 and 8's qemu-server and also pve-qemu, workable but
+    not optimal
+
+* on Kernel/KVM-side we can hook into the set XSAVE ioctl specific to
+  the KVM subsystem, which already reduces chance of regression for
+  all other places. There we have access to the union/struct
+  definitions of the saved state and thus can savely cast to that.
+  We also got access to the vCPU's CPUID capabilities, meaning we can
+  check if the XCR0 (first XSAVE Control Register) reports
+  that it support the PKRU feature, and if it does *NOT* but the
+  saved xfeatures register from XSAVE *DOES* report it, we can safely
+  assume that this combination is due to an migration from an older,
+  leaky kernel – and clear the bit in the xfeature register before
+  restoring it to the guest vCPU KVM state, avoiding the confusing
+  situation that made the vCPU spin at 100%.
+  This should be safe to do, as the guest vCPU CPUID never reported
+  support for the PKRU feature, and it's also a relatively niche and
+  newish feature.
+
+If it gains us something we can drop this patch a bit in the future
+Proxmox VE 9 major release, but we should ensure that VMs that where
+started before PVE 8 cannot be directly live-migrated to the release
+that includes that change; so we should rather only drop it if the
+maintenance burden is high.

-Subject: [PATCH] KVM: VMX: prepare sync_pir_to_irr for running with APICv
- disabled
-
-If APICv is disabled for this vCPU, assigned devices may still attempt to
-post interrupts.  In that case, we need to cancel the vmentry and deliver
-the interrupt with KVM_REQ_EVENT.  Extend the existing code that handles
-injection of L1 interrupts into L2 to cover this case as well.
-
-vmx_hwapic_irr_update is only called when APICv is active so it would be
-confusing to add a check for vcpu->arch.apicv_active in there.  Instead,
-just use vmx_set_rvi directly in vmx_sync_pir_to_irr.

+Subject: [PATCH] KVM: nSVM: Advertise support for flush-by-ASID
+
+Advertise support for FLUSHBYASID when nested SVM is enabled, as KVM can
+always emulate flushing TLB entries for a vmcb12 ASID, e.g. by running L2
+with a new, fresh ASID in vmcb02.  Some modern hypervisors, e.g. VMWare
+Workstation 17, require FLUSHBYASID support and will refuse to run if it's
+not present.
+
+Punt on proper support, as "Honor L1's request to flush an ASID on nested
+VMRUN" is one of the TODO items in the (incomplete) list of issues that
+need to be addressed in order for KVM to NOT do a full TLB flush on every
+nested SVM transition (see nested_svm_transition_tlb_flush()).

+Subject: [PATCH] revert "memfd: improve userspace warnings for missing
+ exec-related flags".
+
+This warning is telling userspace developers to pass MFD_EXEC and
+MFD_NOEXEC_SEAL to memfd_create().  Commit 434ed3350f57 ("memfd: improve
+userspace warnings for missing exec-related flags") made the warning more
+frequent and visible in the hope that this would accelerate the fixing of
+errant userspace.
+
+But the overall effect is to generate far too much dmesg noise.

+Subject: [PATCH] ext4: fallback to complex scan if aligned scan doesn't work
+
+Currently in case the goal length is a multiple of stripe size we use
+ext4_mb_scan_aligned() to find the stripe size aligned physical blocks.
+In case we are not able to find any, we again go back to calling
+ext4_mb_choose_next_group() to search for a different suitable block
+group. However, since the linear search always begins from the start,
+most of the times we end up with the same BG and the cycle continues.
+
+With large fliesystems, the CPU can be stuck in this loop for hours
+which can slow down the whole system. Hence, until we figure out a
+better way to continue the search (rather than starting from beginning)
+in ext4_mb_choose_next_group(), lets just fallback to
+ext4_mb_complex_scan_group() in case aligned scan fails, as it is much
+more likely to find the needed blocks.

+usbnet_probe, the interface keeps configured as random address, although the
+address is correctly read and set during open operation (the only reset
+now).
+
+In order to keep only one reset for the device and to avoid the interface
+always configured as random address, after reset, configure correctly the
+suitable field from the driver, if the mac address is read successfully from
+the device registers or the devicetree. Take into account if a locally
+administered address (random) was previously stored.

+Subject: [PATCH] x86/CPU/AMD: Improve the erratum 1386 workaround
+
+Disable XSAVES only on machines which haven't loaded the microcode
+revision containing the erratum fix.
+
+This will come in handy when running archaic OSes as guests. OSes whose
+brilliant programmers thought that CPUID is overrated and one should not
+query it but use features directly, ala shoot first, ask questions
+later... but only if you're alive after the shooting.
