2024-04-20bcachefs: Fix inode early destruction pathKent Overstreet
discard_new_inode() is the wrong interface to use when we need to free an inode that was never inserted into the inode hash table; we can bypass the whole iput() -> evict() path and replace it with __destroy_inode(); kmem_cache_free() - this fixes a WARN_ON() about I_NEW.

2024-04-20bcachefs: Fix deadlock in journal write pathKent Overstreet
bch2_journal_write() was incorrectly waiting on earlier journal writes synchronously; this usually worked because most of the time we'd be running in the context of a thread that did a journal_buf_put(), but sometimes we'd be running out of the same workqueue that completes those prior journal writes. Additionally, this makes sure to punt to a workqueue before submitting preflushes - we really don't want to be calling submit_bio() in the main transaction commit path.

2024-04-20bcachefs: Tweak btree key cache shrinker so it actually freesKent Overstreet
Freeing key cache items is a multi stage process; we need to wait for an SRCU grace period to elapse, and we handle this ourselves - partially to avoid callback overhead, but primarily so that when allocating we can first allocate from the freed items waiting for an SRCU grace period. Previously, the shrinker was counting the items on the 'waiting for SRCU grace period' lists as items being scanned, but this meant that too many items waiting for an SRCU grace period could prevent it from doing any work at all. After this, we're seeing that items skipped due to the accessed bit are the main cause of the shrinker not making any progress, and we actually want the key cache shrinker to run quite aggressively because reclaimed items will still generally be found (more compactly) in the btree node cache - so we also tweak the shrinker to not count those against nr_to_scan.

2024-04-20bcachefs: bkey_cached.btree_trans_barrier_seq needs to be a ulongKent Overstreet
this stores the SRCU sequence number, which we use to check if an SRCU barrier has elapsed; this is a partial fix for the key cache shrinker not actually freeing. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-04-20Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvmLinus Torvalds
Pull kvm fixes from Paolo Bonzini: "This is a bit on the large side, mostly due to two changes: - Changes to disable some broken PMU virtualization (see below for details under "x86 PMU") - Clean up SVM's enter/exit assembly code so that it can be compiled without OBJECT_FILES_NON_STANDARD. This fixes a warning "Unpatched return thunk in use. This should not happen!" when running KVM selftests. Everything else is small bugfixes and selftest changes: - Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure where KVM would allow userspace to refresh the cache with a bogus GPA. The bug has existed for quite some time, but was exposed by a new sanity check added in 6.9 (to ensure a cache is either GPA-based or HVA-based). - Drop an unused param from gfn_to_pfn_cache_invalidate_start() that got left behind during a 6.9 cleanup. - Fix a math goof in x86's hugepage logic for KVM_SET_MEMORY_ATTRIBUTES that results in an array overflow (detected by KASAN). - Fix a bug where KVM incorrectly clears root_role.direct when userspace sets guest CPUID. - Fix a dirty logging bug in the where KVM fails to write-protect SPTEs used by a nested guest, if KVM is using Page-Modification Logging and the nested hypervisor is NOT using EPT. x86 PMU: - Drop support for virtualizing adaptive PEBS, as KVM's implementation is architecturally broken without an obvious/easy path forward, and because exposing adaptive PEBS can leak host LBRs to the guest, i.e. can leak host kernel addresses to the guest. - Set the enable bits for general purpose counters in PERF_GLOBAL_CTRL at RESET time, as done by both Intel and AMD processors. - Disable LBR virtualization on CPUs that don't support LBR callstacks, as KVM unconditionally uses PERF_SAMPLE_BRANCH_CALL_STACK when creating the perf event, and would fail on such CPUs. Tests: - Fix a flaw in the max_guest_memory selftest that results in it exhausting the supply of ucall structures when run with more than 256 vCPUs. - Mark KVM_MEM_READONLY as supported for RISC-V in set_memory_region_test" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (30 commits) KVM: Drop unused @may_block param from gfn_to_pfn_cache_invalidate_start() KVM: selftests: Add coverage of EPT-disabled to vmx_dirty_log_test KVM: x86/mmu: Fix and clarify comments about clearing D-bit vs. write-protecting KVM: x86/mmu: Remove function comments above clear_dirty_{gfn_range,pt_masked}() KVM: x86/mmu: Write-protect L2 SPTEs in TDP MMU when clearing dirty status KVM: x86/mmu: Precisely invalidate MMU root_role during CPUID update KVM: VMX: Disable LBR virtualization if the CPU doesn't support LBR callstacks perf/x86/intel: Expose existence of callback support to KVM KVM: VMX: Snapshot LBR capabilities during module initialization KVM: x86/pmu: Do not mask LVTPC when handling a PMI on AMD platforms KVM: x86: Snapshot if a vCPU's vendor model is AMD vs. Intel compatible KVM: x86: Stop compiling vmenter.S with OBJECT_FILES_NON_STANDARD KVM: SVM: Create a stack frame in __svm_sev_es_vcpu_run() KVM: SVM: Save/restore args across SEV-ES VMRUN via host save area KVM: SVM: Save/restore non-volatile GPRs in SEV-ES VMRUN via host save area KVM: SVM: Clobber RAX instead of RBX when discarding spec_ctrl_intercepted KVM: SVM: Drop 32-bit "support" from __svm_sev_es_vcpu_run() KVM: SVM: Wrap __svm_sev_es_vcpu_run() with #ifdef CONFIG_KVM_AMD_SEV KVM: SVM: Create a stack frame in __svm_vcpu_run() for unwinding KVM: SVM: Remove a useless zeroing of allocated memory ...

That runtime PM action calls into the clk framework and tries to grab the clk prepare_lock while the disabling of unused clks holds the prepare_lock and is waiting for that runtime PM action to complete.

2024-04-20Revert "svcrdma: Add Write chunk WRs to the RPC's Send WR chain"Chuck Lever
Performance regression reported with NFS/RDMA using Omnipath, bisected to commit e084ee673c77 ("svcrdma: Add Write chunk WRs to the RPC's Send WR chain"). Tracing on the server reports: nfsd-7771 [060] 1758.891809: svcrdma_sq_post_err: cq.id=205 cid=226 sc_sq_avail=13643/851 status=-12 sq_post_err reports ENOMEM, and the rdma->sc_sq_avail (13643) is larger than rdma->sc_sq_depth (851). The number of available Send Queue entries is always supposed to be smaller than the Send Queue depth. That seems like a Send Queue accounting bug in svcrdma. As it's getting to be late in the 6.9-rc cycle, revert this commit. It can be revisited in a subsequent kernel release.

2024-04-19mlxsw: core: Unregister EMAD trap using FORWARD actionIdo Schimmel
The device's manual (PRM - Programmer's Reference Manual) classifies the trap that is used to deliver EMAD responses as an "event trap". Among other things, it means that the only actions that can be associated with the trap are TRAP and FORWARD (NOP). Currently, during driver de-initialization the driver unregisters the trap by setting its action to DISCARD, which violates the above guideline. Future firmware versions will prevent such misuses by returning an error. This does not prevent the driver from working, but an error will be printed to the kernel log during module removal / devlink reload: mlxsw_spectrum 0000:03:00.0: Reg cmd access status failed (status=7(bad parameter)) mlxsw_spectrum 0000:03:00.0: Reg cmd access failed (reg_id=7003(hpkt),type=write) Suppress the error message by aligning the driver to the manual and use a FORWARD (NOP) action when unregistering the trap.

Changes since v1: - makefile and kernel config are updated to have all required features - fix makefile with missing bits to make kselftest-install work - test it via vng as per https://github.com/linux-netdev/nipa/wiki/How-to-run-netdev-selftests-CI-style (Thanks Jakub!) - squash a few fixes, e.g. nft_queue.sh v1 had a race w. NFNETLINK_QUEUE=m - add a settings file with 8m timeout, for nft_concat_range.sh sake. That script can be sped up a bit, I think, but its not contained in this batch yet. - toss the first two bogus rebase artifacts (Matthieu Baerts) scripts are moved to lib.sh infra.

If "udp_cmsg_send()" returned 0 (i.e. only UDP cmsg), "connected" should not be set to 0. Otherwise it stops the connected socket from using the cached route.

2024-04-19ksmbd: common: use struct_group_attr instead of struct_group for ↵Namjae Jeon
network_open_info 4byte padding cause the connection issue with the applications of MacOS. smb2_close response size increases by 4 bytes by padding, And the smb client of MacOS check it and stop the connection. This patch use struct_group_attr instead of struct_group for network_open_info to use __packed to avoid padding.

2024-04-19ksmbd: clear RENAME_NOREPLACE before calling vfs_renameMarios Makassikis
File overwrite case is explicitly handled, so it is not necessary to pass RENAME_NOREPLACE to vfs_rename. Clearing the flag fixes rename operations when the share is a ntfs-3g mount. The latter uses an older version of fuse with no support for flags in the ->rename op.

2024-04-19ksmbd: validate request buffer size in smb2_allocate_rsp_buf()Namjae Jeon
The response buffer should be allocated in smb2_allocate_rsp_buf before validating request. But the fields in payload as well as smb2 header is used in smb2_allocate_rsp_buf(). This patch add simple buffer size validation to avoid potencial out-of-bounds in request buffer.

2024-04-19ksmbd: fix slab-out-of-bounds in smb2_allocate_rsp_bufNamjae Jeon
If ->ProtocolId is SMB2_TRANSFORM_PROTO_NUM, smb2 request size validation could be skipped. if request size is smaller than sizeof(struct smb2_query_info_req), slab-out-of-bounds read can happen in smb2_allocate_rsp_buf(). This patch allocate response buffer after decrypting transform request. smb3_decrypt_req() will validate transform request size and avoid slab-out-of-bound in smb2_allocate_rsp_buf().

2024-04-19Merge branch 'use network helpers, part 1'Martin KaFai Lau
Geliang Tang says: ==================== v5: - address Martin's comments for v4. (thanks) - drop start_server_addr_opts, add opts as a argument of start_server_addr. - add opts argument for connect_to_addr too. - move some patches out of this set, stay with start_server_addr() and connect_to_addr() only in it. v4: - add more patches using make_sockaddr and get_socket_local_port helpers. v3: - address comments of Martin and Eduard in v2. (thanks) - move "int type" to the first argument of start_server_addr and connect_to_addr. - add start_server_addr_opts. - using "sockaddr_storage" instead of "sockaddr". - move start_server_setsockopt patches out of this series. v2: - update patch 6 only, fix errors reported by CI. This patchset uses public helpers start_server_* and connect_to_* defined in network_helpers.c to drop duplicate code. ==================== Signed-off-by: Martin KaFai Lau <martin.lau@kernel.org>
2024-04-19selftests/bpf: Use connect_to_addr in sk_assignGeliang Tang
This patch uses public helper connect_to_addr() exported in network_helpers.h instead of the local defined function connect_to_server() in prog_tests/sk_assign.c. This can avoid duplicate code. The code that sets SO_SNDTIMEO timeout as timeo_sec (3s) can be dropped, since connect_to_addr() sets default timeout as 3s.

In order to pair up with connect_to_addr(), this patch adds a new helper start_server_addr(), which is a wrapper of __start_server().
