However, we started counting one id too late and thus lost 4294967296 as the first valid id. Fix that. - Update a few comments on some vfs_*() creation helpers. - Move copying of the xattr name out from the locks required to start a filesystem write. - Extend the filelock lock UAF fix to the compat code as well. - Now that we added the ability to look up an inode under RCU it's possible that lockless hash lookup can find and lock an inode after it gets I_FREEING set. It then waits until inode teardown in evict() is finished. The flag however is still set after evict() has woken up all waiters. If the inode lock is taken late enough on the waiting side after hash removal and wakeup happened the waiting thread will never be woken. Before RCU based lookup this was synchronized via the inode_hash_lock. But since unhashing requires the inode lock as well we can check whether the inode is unhashed while holding inode lock even without holding inode_hash_lock. pidfd: - The nsproxy structure contains nearly all of the namespaces associated with a task. When a namespace type isn't supported nsproxy might contain a NULL pointer or always point to the initial namespace type. The logic isn't consistent. So when deriving namespace fds we need to ensure that the namespace type is supported. First, so that we don't risk dereferncing NULL pointers. The correct bigger fix would be to change all namespaces to always set a valid namespace pointer in struct nsproxy independent of whether or not it is compiled in. But that requires quite a few changes. Second, so that we don't allow deriving namespace fds when the namespace type doesn't exist and thus when they couldn't also be derived via /proc/self/ns/. - Add missing selftests for the new pidfd ioctls to derive namespace fds. This simply extends the already existing testsuite. netfs: - Fix debug logging and fix kconfig variable name so it actually works. - Fix writeback that goes both to the server and cache. The streams are only activated once a subreq is added. When a server write happens the subreq doesn't need to have finished by the time the cache write is started. If the server write has already finished by the time the cache write is about to start the cache write will operate on a folio that might already have been reused. Fix this by preactivating the cache write. - Limit cachefiles subreq size for cache writes to MAX_RW_COUNT" * tag 'vfs-6.11-rc1.fixes.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: inode: clarify what's locked vfs: Fix potential circular locking through setxattr() and removexattr() filelock: Fix fcntl/close race recovery compat path fs: use all available ids cachefiles: Set the max subreq size for cache writes to MAX_RW_COUNT netfs: Fix writeback that needs to go to both server and cache pidfs: add selftests for new namespace ioctls pidfs: handle kernels without namespaces cleanly pidfs: when time ns disabled add check for ioctl vfs: correct the comments of vfs_*() helpers vfs: handle __wait_on_freeing_inode() and evict() race netfs: Rename CONFIG_FSCACHE_DEBUG to CONFIG_NETFS_DEBUG netfs: Revert "netfs: Switch debug logging to pr_debug()" |

- 875fa64577 ("mm/hugetlb_vmemmap: fix race with speculative PFN
walkers") is known to cause a performance regression (https://lore.kernel.org/all/3acefad9-96e5-4681-8014-827d6be71c7a@linux.ibm.com/T/#mfa809800a7862fb5bdf834c6f71a3a5113eb83ff). Yu has a fix which I'll send along later via the hotfixes branch. - In the series "mm: Avoid possible overflows in dirty throttling" Jan Kara addresses a couple of issues in the writeback throttling code. These fixes are also targetted at -stable kernels. - Ryusuke Konishi's series "nilfs2: fix potential issues related to reserved inodes" does that. This should actually be in the mm-nonmm-stable tree, along with the many other nilfs2 patches.

ARM:
* Initial infrastructure for shadow stage-2 MMUs, as part of nested virtualization enablement * Support for userspace changes to the guest CTR_EL0 value, enabling (in part) migration of VMs between heterogenous hardware * Fixes + improvements to pKVM's FF-A proxy, adding support for v1.1 of the protocol * FPSIMD/SVE support for nested, including merged trap configuration and exception routing * New command-line parameter to control the WFx trap behavior under KVM * Introduce kCFI hardening in the EL2 hypervisor * Fixes + cleanups for handling presence/absence of FEAT_TCRX * Miscellaneous fixes + documentation updates LoongArch: * Add paravirt steal time support. * Add support for KVM_DIRTY_LOG_INITIALLY_SET. * Add perf kvm-stat support for loongarch. RISC-V: * Redirect AMO load/store access fault traps to guest * perf kvm stat support * Use guest files for IMSIC virtualization, when available ONE_REG support for the Zimop, Zcmop, Zca, Zcf, Zcd, Zcb and Zawrs ISA extensions is coming through the RISC-V tree. s390: * Assortment of tiny fixes which are not time critical x86: * Fixes for Xen emulation. * Add a global struct to consolidate tracking of host values, e.g. EFER * Add KVM_CAP_X86_APIC_BUS_CYCLES_NS to allow configuring the effective APIC bus frequency, because TDX. * Print the name of the APICv/AVIC inhibits in the relevant tracepoint. * Clean up KVM's handling of vendor specific emulation to consistently act on "compatible with Intel/AMD", versus checking for a specific vendor. * Drop MTRR virtualization, and instead always honor guest PAT on CPUs that support self-snoop. * Update to the newfangled Intel CPU FMS infrastructure. * Don't advertise IA32_PERF_GLOBAL_OVF_CTRL as an MSR-to-be-saved, as it reads '0' and writes from userspace are ignored. * Misc cleanups x86 - MMU: * Small cleanups, renames and refactoring extracted from the upcoming Intel TDX support. * Don't allocate kvm_mmu_page.shadowed_translation for shadow pages that can't hold leafs SPTEs. * Unconditionally drop mmu_lock when allocating TDP MMU page tables for eager page splitting, to avoid stalling vCPUs when splitting huge pages. * Bug the VM instead of simply warning if KVM tries to split a SPTE that is non-present or not-huge. KVM is guaranteed to end up in a broken state because the callers fully expect a valid SPTE, it's all but dangerous to let more MMU changes happen afterwards. x86 - AMD: * Make per-CPU save_area allocations NUMA-aware. * Force sev_es_host_save_area() to be inlined to avoid calling into an instrumentable function from noinstr code. * Base support for running SEV-SNP guests. API-wise, this includes a new KVM_X86_SNP_VM type, encrypting/measure the initial image into guest memory, and finalizing it before launching it. Internally, there are some gmem/mmu hooks needed to prepare gmem-allocated pages before mapping them into guest private memory ranges. This includes basic support for attestation guest requests, enough to say that KVM supports the GHCB 2.0 specification. There is no support yet for loading into the firmware those signing keys to be used for attestation requests, and therefore no need yet for the host to provide certificate data for those keys. To support fetching certificate data from userspace, a new KVM exit type will be needed to handle fetching the certificate from userspace. An attempt to define a new KVM_EXIT_COCO/KVM_EXIT_COCO_REQ_CERTS exit type to handle this was introduced in v1 of this patchset, but is still being discussed by community, so for now this patchset only implements a stub version of SNP Extended Guest Requests that does not provide certificate data. x86 - Intel: * Remove an unnecessary EPT TLB flush when enabling hardware. * Fix a series of bugs that cause KVM to fail to detect nested pending posted interrupts as valid wake eents for a vCPU executing HLT in L2 (with HLT-exiting disable by L1). * KVM: x86: Suppress MMIO that is triggered during task switch emulation Explicitly suppress userspace emulated MMIO exits that are triggered when emulating a task switch as KVM doesn't support userspace MMIO during complex (multi-step) emulation. Silently ignoring the exit request can result in the WARN_ON_ONCE(vcpu->mmio_needed) firing if KVM exits to userspace for some other reason prior to purging mmio_needed. See commit |

selftests/vDSO: add tests for vgetrandom
This adds two tests for vgetrandom. The first one, vdso_test_chacha, simply checks that the assembly implementation of chacha20 matches that of libsodium, a basic sanity check that should catch most errors. The second, vdso_test_getrandom, is a full "libc-like" implementation of the userspace side of vgetrandom() support. It's meant to be used also as example code for libcs that might be integrating this. Cc: linux-kselftest@vger.kernel.org Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> |

mm: add MAP_DROPPABLE for designating always lazily freeable mappings
The vDSO getrandom() implementation works with a buffer allocated with a new system call that has certain requirements: - It shouldn't be written to core dumps. * Easy: VM_DONTDUMP. - It should be zeroed on fork. * Easy: VM_WIPEONFORK. - It shouldn't be written to swap. * Uh-oh: mlock is rlimited. * Uh-oh: mlock isn't inherited by forks. - It shouldn't reserve actual memory, but it also shouldn't crash when page faulting in memory if none is available * Uh-oh: VM_NORESERVE means segfaults. It turns out that the vDSO getrandom() function has three really nice characteristics that we can exploit to solve this problem: 1) Due to being wiped during fork(), the vDSO code is already robust to having the contents of the pages it reads zeroed out midway through the function's execution. 2) In the absolute worst case of whatever contingency we're coding for, we have the option to fallback to the getrandom() syscall, and everything is fine. 3) The buffers the function uses are only ever useful for a maximum of 60 seconds -- a sort of cache, rather than a long term allocation. These characteristics mean that we can introduce VM_DROPPABLE, which has the following semantics: a) It never is written out to swap. b) Under memory pressure, mm can just drop the pages (so that they're zero when read back again). c) It is inherited by fork. d) It doesn't count against the mlock budget, since nothing is locked. e) If there's not enough memory to service a page fault, it's not fatal, and no signal is sent. This way, allocations used by vDSO getrandom() can use: VM_DROPPABLE | VM_DONTDUMP | VM_WIPEONFORK | VM_NORESERVE And there will be no problem with OOMing, crashing on overcommitment, using memory when not in use, not wiping on fork(), coredumps, or writing out to swap. In order to let vDSO getrandom() use this, expose these via mmap(2) as MAP_DROPPABLE. Note that this involves removing the MADV_FREE special case from sort_folio(), which according to Yu Zhao is unnecessary and will simply result in an extra call to shrink_folio_list() in the worst case. The chunk removed reenables the swapbacked flag, which we don't want for VM_DROPPABLE, and we can't conditionalize it here because there isn't a vma reference available. Finally, the provided self test ensures that this is working as desired. Cc: linux-mm@kvack.org Acked-by: David Hildenbrand <david@redhat.com> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> |

The revised version has simpler logic. - Shared branch with iommu for handle support when doing domain attach. Handles allow the domain owner to include additional private data on a per-device basis. - IO Page Fault Reporting to userspace via iommufd.

ftrace: Rewrite of function graph tracer
Up until now, the function graph tracer could only have a single user attached to it. If another user tried to attach to the function graph tracer while one was already attached, it would fail. Allowing function graph tracer to have more than one user has been asked for since 2009, but it required a rewrite to the logic to pull it off so it never happened. Until now! There's three systems that trace the return of a function. That is kretprobes, function graph tracer, and BPF. kretprobes and function graph tracing both do it similarly. The difference is that kretprobes uses a shadow stack per callback and function graph tracer creates a shadow stack for all tasks. The function graph tracer method makes it possible to trace the return of all functions. As kretprobes now needs that feature too, allowing it to use function graph tracer was needed. BPF also wants to trace the return of many probes and its method doesn't scale either. Having it use function graph tracer would improve that.

If another user tried to attach to the function graph tracer while one was already attached, it would fail. Allowing function graph tracer to have more than one user has been asked for since 2009, but it required a rewrite to the logic to pull it off so it never happened. Until now! There's three systems that trace the return of a function. That is kretprobes, function graph tracer, and BPF. kretprobes and function graph tracing both do it similarly. The difference is that kretprobes uses a shadow stack per callback and function graph tracer creates a shadow stack for all tasks. The function graph tracer method makes it possible to trace the return of all functions. As kretprobes now needs that feature too, allowing it to use function graph tracer was needed. BPF also wants to trace the return of many probes and its method doesn't scale either. Having it use function graph tracer would improve that.

Probes updates for v6.11:
Uprobes: - x86/shstk: Make return uprobe work with shadow stack. - Add uretprobe syscall which speeds up the uretprobe 10-30% faster. This syscall is automatically used from user-space trampolines which are generated by the uretprobe. If this syscall is used by normal user program, it will cause SIGILL. Note that this is currently only implemented on x86_64. (This also has 2 fixes for adjusting the syscall number to avoid conflict with new *attrat syscalls.) - uprobes/perf: fix user stack traces in the presence of pending uretprobe. This corrects the uretprobe's trampoline address in the stacktrace with correct return address. - selftests/x86: Add a return uprobe with shadow stack test. - selftests/bpf: Add uretprobe syscall related tests. . test case for register integrity check. . test case with register changing case. . test case for uretprobe syscall without uprobes (expected to be failed). . test case for uretprobe with shadow stack. - selftests/bpf: add test validating uprobe/uretprobe stack traces - MAINTAINERS: Add uprobes entry. This does not specify the tree but to clarify who maintains and reviews the uprobes. Kprobes: - tracing/kprobes: Test case cleanups. Replace redundant WARN_ON_ONCE() + pr_warn() with WARN_ONCE() and remove unnecessary code from selftest. - tracing/kprobes: Add symbol counting check when module loads.

kselftest/alsa: Use card name rather than number in test names
Currently for the PCM and mixer tests we report test names which identify the card being tested with the card number. This ensures we have unique names but since card numbers are dynamically assigned at runtime the names we end up with will often not be stable on systems with multiple cards especially where those cards are provided by separate modules loeaded at runtime. This makes it difficult for automated systems and UIs to relate test results between runs on affected platforms. Address this by replacing our use of card numbers with card names which are more likely to be stable across runs. We use the card ID since it is guaranteed to be unique by default, unlike the long name. There is still some vulnerability to ordering issues if multiple cards with the same base ID are present in the system but have separate dependencies but not all drivers put distinguishing information in their long names.

ipv4: Fix incorrect TOS in fibmatch route get reply
The TOS value that is returned to user space in the route get reply is
the one with which the lookup was performed ('fl4->flowi4_tos'). This is
fine when the matched route is configured with a TOS as it would not
match if its TOS value did not match the one with which the lookup was
performed.
However, matching on TOS is only performed when the route's TOS is not
zero. It is therefore possible to have the kernel incorrectly return a
non-zero TOS:
# ip link add name dummy1 up type dummy
# ip address add 192.0.2.1/24 dev dummy1
# ip route get fibmatch 192.0.2.2 tos 0xfc
192.0.2.0/24 tos 0x1c dev dummy1 proto kernel scope link src 192.0.2.1
Fix by instead returning the DSCP field from the FIB result structure
which was populated during the route lookup.
Output after the patch:
# ip link add name dummy1 up type dummy
# ip address add 192.0.2.1/24 dev dummy1
# ip route get fibmatch 192.0.2.2 tos 0xfc
192.0.2.0/24 dev dummy1 proto kernel scope link src 192.0.2.1
Extend the existing selftests to not only verify that the correct route
is returned, but that it is also returned with correct "tos" value (or
without it).

selftests/bpf: Test sockmap redirect for AF_UNIX MSG_OOB
Verify that out-of-band packets are silently dropped before they reach the redirection logic. The idea is to test with a 2 byte long send(). Should a MSG_OOB flag be in use, only the last byte will be treated as out-of-band. Test fails if verd_mapfd indicates a wrong number of packets processed (e.g. if OOB wasn't dropped at the source) or if it was possible to recv() MSG_OOB from the mapped socket, or if any stale OOB data have been left reachable from the unmapped socket.

libbpf: Fix no-args func prototype BTF dumping syntax
For all these years libbpf's BTF dumper has been emitting not strictly
valid syntax for function prototypes that have no input arguments.
Instead of `int (*blah)()` we should emit `int (*blah)(void)`.
This is not normally a problem, but it manifests when we get kfuncs in
vmlinux.h that have no input arguments. Due to compiler internal
specifics, we get no BTF information for such kfuncs, if they are not
declared with proper `(void)`.
The fix is trivial. We also need to adjust a few ancient tests that
happily assumed `()` is correct.

selftests/bpf: fexit_sleep: Fix stack allocation for arm64
On ARM64 the stack pointer should be aligned at a 16 byte boundary or
the SPAlignmentFault can occur. The fexit_sleep selftest allocates the
stack for the child process as a character array, this is not guaranteed
to be aligned at 16 bytes.
Because of the SPAlignmentFault, the child process is killed before it
can do the nanosleep call and hence fentry_cnt remains as 0. This causes
the main thread to hang on the following line:
while (READ_ONCE(fexit_skel->bss->fentry_cnt) != 2);
Fix this by allocating the stack using mmap() as described in the
example in the man page of clone().
Remove the fexit_sleep test from the DENYLIST of arm64.

Networking changes for 6.11. Not much excitement - a handful of large
patchsets (devmem among them) did not make it in time. Core & protocols ---------------- - Use local_lock in addition to local_bh_disable() to protect per-CPU resources in networking, a step closer for local_bh_disable() not to act as a big lock on PREEMPT_RT. - Use flex array for netdevice priv area, ensure its cache alignment. - Add a sysctl knob to allow user to specify a default rto_min at socket init time. Bit of a big hammer but multiple companies were independently carrying such patch downstream so clearly it's useful. - Support scheduling transmission of packets based on CLOCK_TAI. - Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off using cpusets. - Support multiple L2TPv3 UDP tunnels using the same 5-tuple address. - Allow configuration of multipath hash seed, to both allow synchronizing hashing of two routers, and preventing partial accidental sync. - Improve TCP compliance with RFC 9293 for simultaneous connect(). - Support sending NAT keepalives in IPsec ESP in UDP states. Userspace IKE daemon had to do this before, but the kernel can better keep track of it. - Support sending supervision HSR frames with MAC addresses stored in ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled. - Introduce IPPROTO_SMC for selecting SMC when socket is created. - Allow UDP GSO transmit from devices with no checksum offload. - openvswitch: add packet sampling via psample, separating the sampled traffic from "upcall" packets sent to user space for forwarding. - nf_tables: shrink memory consumption for transaction objects. Things we sprinkled into general kernel code -------------------------------------------- - Power Sequencing subsystem (used by Qualcomm Bluetooth driver for QCA6390). - Add IRQ information in sysfs for auxiliary bus. - Introduce guard definition for local_lock. - Add aligned flavor of __cacheline_group_{begin, end}() markings for grouping fields in structures. BPF --- - Notify user space (via epoll) when a struct_ops object is getting detached/unregistered. - Add new kfuncs for a generic, open-coded bits iterator. - Enable BPF programs to declare arrays of kptr, bpf_rb_root, and bpf_list_head. - Support resilient split BTF which cuts down on duplication and makes BTF as compact as possible WRT BTF from modules. - Add support for dumping kfunc prototypes from BTF which enables both detecting as well as dumping compilable prototypes for kfuncs. - riscv64 BPF JIT improvements in particular to add 12-argument support for BPF trampolines and to utilize bpf_prog_pack for the latter. - Add the capability to offload the netfilter flowtable in XDP layer through kfuncs. Driver API ---------- - Allow users to configure IRQ tresholds between which automatic IRQ moderation can choose. - Expand Power Sourcing (PoE) status with power, class and failure reason. Support setting power limits. - Track additional RSS contexts in the core, make sure configuration changes don't break them. - Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP data paths. - Support updating firmware on SFP modules. Tests and tooling ----------------- - mptcp: use net/lib.sh to manage netns. - TCP-AO and TCP-MD5: replace debug prints used by tests with tracepoints. - openvswitch: make test self-contained (don't depend on OvS CLI tools). Drivers ------- - Ethernet high-speed NICs: - Broadcom (bnxt): - increase the max total outstanding PTP TX packets to 4 - add timestamping statistics support - implement netdev_queue_mgmt_ops - support new RSS context API - Intel (100G, ice, idpf): - implement FEC statistics and dumping signal quality indicators - support E825C products (with 56Gbps PHYs) - nVidia/Mellanox: - support HW-GRO - mlx4/mlx5: support per-queue statistics via netlink - obey the max number of EQs setting in sub-functions - AMD/Solarflare: - support new RSS context API - AMD/Pensando: - ionic: rework fix for doorbell miss to lower overhead and skip it on new HW - Wangxun: - txgbe: support Flow Director perfect filters - Ethernet NICs consumer, embedded and virtual: - Add driver for Tehuti Networks TN40xx chips - Add driver for Meta's internal NIC chips - Add driver for Ethernet MAC on Airoha EN7581 SoCs - Add driver for Renesas Ethernet-TSN devices - Google cloud vNIC: - flow steering support - Microsoft vNIC: - support page sizes other than 4KB on ARM64 - vmware vNIC: - support latency measurement (update to version 9) - VirtIO net: - support for Byte Queue Limits - support configuring thresholds for automatic IRQ moderation - support for AF_XDP Rx zero-copy - Synopsys (stmmac): - support for STM32MP13 SoC - let platforms select the right PCS implementation - TI: - icssg-prueth: add multicast filtering support - icssg-prueth: enable PTP timestamping and PPS - Renesas: - ravb: improve Rx performance 30-400% by using page pool, theaded NAPI and timer-based IRQ coalescing -

a handful of large patchsets (devmem among them) did not make it in time. Core & protocols: - Use local_lock in addition to local_bh_disable() to protect per-CPU resources in networking, a step closer for local_bh_disable() not to act as a big lock on PREEMPT_RT - Use flex array for netdevice priv area, ensure its cache alignment - Add a sysctl knob to allow user to specify a default rto_min at socket init time. Bit of a big hammer but multiple companies were independently carrying such patch downstream so clearly it's useful - Support scheduling transmission of packets based on CLOCK_TAI - Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off using cpusets - Support multiple L2TPv3 UDP tunnels using the same 5-tuple address - Allow configuration of multipath hash seed, to both allow synchronizing hashing of two routers, and preventing partial accidental sync - Improve TCP compliance with RFC 9293 for simultaneous connect() - Support sending NAT keepalives in IPsec ESP in UDP states. Userspace IKE daemon had to do this before, but the kernel can better keep track of it - Support sending supervision HSR frames with MAC addresses stored in ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled - Introduce IPPROTO_SMC for selecting SMC when socket is created - Allow UDP GSO transmit from devices with no checksum offload - openvswitch: add packet sampling via psample, separating the sampled traffic from "upcall" packets sent to user space for forwarding - nf_tables: shrink memory consumption for transaction objects Things we sprinkled into general kernel code: - Power Sequencing subsystem (used by Qualcomm Bluetooth driver for QCA6390) [ Already merged separately - Linus ] - Add IRQ information in sysfs for auxiliary bus - Introduce guard definition for local_lock - Add aligned flavor of __cacheline_group_{begin, end}() markings for grouping fields in structures BPF: - Notify user space (via epoll) when a struct_ops object is getting detached/unregistered - Add new kfuncs for a generic, open-coded bits iterator - Enable BPF programs to declare arrays of kptr, bpf_rb_root, and bpf_list_head - Support resilient split BTF which cuts down on duplication and makes BTF as compact as possible WRT BTF from modules - Add support for dumping kfunc prototypes from BTF which enables both detecting as well as dumping compilable prototypes for kfuncs - riscv64 BPF JIT improvements in particular to add 12-argument support for BPF trampolines and to utilize bpf_prog_pack for the latter - Add the capability to offload the netfilter flowtable in XDP layer through kfuncs Driver API: - Allow users to configure IRQ tresholds between which automatic IRQ moderation can choose - Expand Power Sourcing (PoE) status with power, class and failure reason. Support setting power limits - Track additional RSS contexts in the core, make sure configuration changes don't break them - Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP data paths - Support updating firmware on SFP modules Tests and tooling: - mptcp: use net/lib.sh to manage netns - TCP-AO and TCP-MD5: replace debug prints used by tests with tracepoints - openvswitch: make test self-contained (don't depend on OvS CLI tools) Drivers: - Ethernet high-speed NICs: - Broadcom (bnxt): - increase the max total outstanding PTP TX packets to 4 - add timestamping statistics support - implement netdev_queue_mgmt_ops - support new RSS context API - Intel (100G, ice, idpf): - implement FEC statistics and dumping signal quality indicators - support E825C products (with 56Gbps PHYs) - nVidia/Mellanox: - support HW-GRO - mlx4/mlx5: support per-queue statistics via netlink - obey the max number of EQs setting in sub-functions - AMD/Solarflare: - support new RSS context API - AMD/Pensando: - ionic: rework fix for doorbell miss to lower overhead and skip it on new HW - Wangxun: - txgbe: support Flow Director perfect filters - Ethernet NICs consumer, embedded and virtual: - Add driver for Tehuti Networks TN40xx chips - Add driver for Meta's internal NIC chips - Add driver for Ethernet MAC on Airoha EN7581 SoCs - Add driver for Renesas Ethernet-TSN devices - Google cloud vNIC: - flow steering support - Microsoft vNIC: - support page sizes other than 4KB on ARM64 - vmware vNIC: - support latency measurement (update to version 9) -

KVM generic changes for 6.11
- Enable halt poll shrinking by default, as Intel found it to be a clear win. - Setup empty IRQ routing when creating a VM to avoid having to synchronize SRCU when creating a split IRQCHIP on x86. - Rework the sched_in/out() paths to replace kvm_arch_sched_in() with a flag that arch code can use for hooking both sched_in() and sched_out(). - Take the vCPU @id as an "unsigned long" instead of "u32" to avoid truncating a bogus value from userspace, e.g. to help userspace detect bugs. - Mark a vCPU as preempted if and only if it's scheduled out while in the KVM_RUN loop, e.g. to avoid marking it preempted and thus writing guest memory when retrieving guest state during live migration blackout. - A few minor cleanups -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKTobbabEP7vbhhN9OlYIJqCjN/0FAmaRuOYACgkQOlYIJqCj N/1UnQ/8CI5Qfr+/0gzYgtWmtEMczGG+rMNpzD3XVqPjJjXcMcBiQnplnzUVLhha vlPdYVK7vgmEt003XGzV55mik46LHL+DX/v4hI3HEdblfyCeNLW3fKEWVRB44qJe o+YUQwSK42SORUp9oXuQINxhA//U9EnI7CQxlJ8w8wenv5IJKfIGr01DefmfGPAV PKm9t6WLcNqvhZMEyy/zmzM3KVPCJL0NcwI97x6sHxFpQYIDtL0E/VexA4AFqMoT QK7cSDC/2US41Zvem/r/GzM/ucdF6vb9suzZYBohwhxtVhwJe2CDeYQZvtNKJ1U7 GOHPaKL6nBWdZCm/yyWbbX2nstY1lHqxhN3JD0X8wqU5rNcwm2b8Vfyav0Ehc7H+ jVbDTshOx4YJmIgajoKjgM050rdBK59TdfVL+l+AAV5q/TlHocalYtvkEBdGmIDg 2td9UHSime6sp20vQfczUEz4bgrQsh4l2Fa/qU2jFwLievnBw0AvEaMximkSGMJe b8XfjmdTjlOesWAejANKtQolfrq14+1wYw0zZZ8PA+uNVpKdoovmcqSOcaDC9bT8 GO/NFUvoG+lkcvJcIlo1SSl81SmGLosijwxWfGvFAqsgpR3/3l3dYp0QtztoCNJO d3+HnjgYn5o5FwufuTD3eUOXH4AFjG108DH0o25XrIkb2Kymy0o= =BalU -----END PGP SIGNATURE----- Merge tag 'kvm-x86-generic-6.11' of https://github.com/kvm-x86/linux into HEAD KVM generic changes for 6.11 - Enable halt poll shrinking by default, as Intel found it to be a clear win. - Setup empty IRQ routing when creating a VM to avoid having to synchronize SRCU when creating a split IRQCHIP on x86. - Rework the sched_in/out() paths to replace kvm_arch_sched_in() with a flag that arch code can use for hooking both sched_in() and sched_out(). - Take the vCPU @id as an "unsigned long" instead of "u32" to avoid truncating a bogus value from userspace, e.g. to help userspace detect bugs. - Mark a vCPU as preempted if and only if it's scheduled out while in the KVM_RUN loop, e.g. to avoid marking it preempted and thus writing guest memory when retrieving guest state during live migration blackout. - A few minor cleanups |
