2024-04-22NFC: trf7970a: disable all regulators on removalPaul Geurts1-19/+23
During module probe, regulator 'vin' and 'vdd-io' are used and enabled, but the vdd-io regulator overwrites the 'vin' regulator pointer. During remove, only the vdd-io is disabled, as the vin regulator pointer is not available anymore. When regulator_put() is called during resource cleanup a kernel warning is given, as the regulator is still enabled. Store the two regulators in separate pointers and disable both the regulators on module remove.

2024-04-22net: dsa: mv88e6xx: fix supported_interfaces setup in ↵Matthias Schiffer2-8/+71
mv88e6250_phylink_get_caps() With the recent PHYLINK changes requiring supported_interfaces to be set, MV88E6250 family switches like the 88E6020 fail to probe - cmode is never initialized on these devices, so mv88e6250_phylink_get_caps() does not set any supported_interfaces flags. Instead of a cmode, on 88E6250 we have a read-only port mode value that encodes similar information. There is no reason to bother mapping port mode to the cmodes of other switch models; instead we introduce a mv88e6250_setup_supported_interfaces() that is called directly from mv88e6250_phylink_get_caps().

2024-04-22xdp: use flags field to disambiguate broadcast redirectToke Høiland-Jørgensen1-10/+32
When redirecting a packet using XDP, the bpf_redirect_map() helper will set up the redirect destination information in struct bpf_redirect_info (using the __bpf_xdp_redirect_map() helper function), and the xdp_do_redirect() function will read this information after the XDP program returns and pass the frame on to the right redirect destination. When using the BPF_F_BROADCAST flag to do multicast redirect to a whole map, __bpf_xdp_redirect_map() sets the 'map' pointer in struct bpf_redirect_info to point to the destination map to be broadcast. And xdp_do_redirect() reacts to the value of this map pointer to decide whether it's dealing with a broadcast or a single-value redirect. However, if the destination map is being destroyed before xdp_do_redirect() is called, the map pointer will be cleared out (by bpf_clear_redirect_map()) without waiting for any XDP programs to stop running. This causes xdp_do_redirect() to think that the redirect was to a single target, but the target pointer is also NULL (since broadcast redirects don't have a single target), so this causes a crash when a NULL pointer is passed to dev_map_enqueue(). To fix this, change xdp_do_redirect() to react directly to the presence of the BPF_F_BROADCAST flag in the 'flags' value in struct bpf_redirect_info to disambiguate between a single-target and a broadcast redirect. And only read the 'map' pointer if the broadcast flag is set, aborting if that has been cleared out in the meantime. This prevents the crash, while keeping the atomic (cmpxchg-based) clearing of the map pointer itself, and without adding any more checks in the non-broadcast fast path.

forceuid/forcegid should be enabled by default when uid=/gid= options are specified, but commit 24e0a1eff9e2 ("cifs: switch to new mount api") changed the behavior. Due to the change, a mounted share does not show intentional uid/gid for files and directories even though uid=/gid= options are specified since forceuid/forcegid are not enabled.

2024-04-22arm32, bpf: Reimplement sign-extension mov instructionPuranjay Mohan1-13/+43
The current implementation of the mov instruction with sign extension has the following problems: 1. It clobbers the source register if it is not stacked because it sign extends the source and then moves it to the destination. 2. If the dst_reg is stacked, the current code doesn't write the value back in case of 64-bit mov. 3. There is room for improvement by emitting fewer instructions. The steps for fixing this and the instructions emitted by the JIT are explained below with examples in all combinations: Case A: offset == 32: ===================== Case A.1: src and dst are stacked registers: -------------------------------------------- 1. Load src_lo into tmp_lo 2. Store tmp_lo into dst_lo 3. Sign extend tmp_lo into tmp_hi 4. Store tmp_hi to dst_hi Example: r3 = (s32)r3 r3 is a stacked register ldr r6, [r11, #-16] // Load r3_lo into tmp_lo // str to dst_lo is not emitted because src_lo == dst_lo asr r7, r6, #31 // Sign extend tmp_lo into tmp_hi str r7, [r11, #-12] // Store tmp_hi into r3_hi Case A.2: src is stacked but dst is not: ---------------------------------------- 1. Load src_lo into dst_lo 2. Sign extend dst_lo into dst_hi Example: r6 = (s32)r3 r6 maps to {ARM_R5, ARM_R4} and r3 is stacked ldr r4, [r11, #-16] // Load r3_lo into r6_lo asr r5, r4, #31 // Sign extend r6_lo into r6_hi Case A.3: src is not stacked but dst is stacked: ------------------------------------------------ 1. Store src_lo into dst_lo 2. Sign extend src_lo into tmp_hi 3. Store tmp_hi to dst_hi Example: r3 = (s32)r6 r3 is stacked and r6 maps to {ARM_R5, ARM_R4} str r4, [r11, #-16] // Store r6_lo to r3_lo asr r7, r4, #31 // Sign extend r6_lo into tmp_hi str r7, [r11, #-12] // Store tmp_hi to dest_hi Case A.4: Both src and dst are not stacked: ------------------------------------------- 1. Mov src_lo into dst_lo 2. Sign extend src_lo into dst_hi Example: (bf) r6 = (s32)r6 r6 maps to {ARM_R5, ARM_R4} // Mov not emitted because dst == src asr r5, r4, #31 // Sign extend r6_lo into r6_hi Case B: offset != 32: ===================== Case B.1: src and dst are stacked registers: -------------------------------------------- 1. Load src_lo into tmp_lo 2. Sign extend tmp_lo according to offset. 3. Store tmp_lo into dst_lo 4. Sign extend tmp_lo into tmp_hi 5. Store tmp_hi to dst_hi Example: r9 = (s8)r3 r9 and r3 are both stacked registers ldr r6, [r11, #-16] // Load r3_lo into tmp_lo lsl r6, r6, #24 // Sign extend tmp_lo asr r6, r6, #24 // .. str r6, [r11, #-56] // Store tmp_lo to r9_lo asr r7, r6, #31 // Sign extend tmp_lo to tmp_hi str r7, [r11, #-52] // Store tmp_hi to r9_hi Case B.2: src is stacked but dst is not: ---------------------------------------- 1. Load src_lo into dst_lo 2. Sign extend dst_lo according to offset. 3. Sign extend tmp_lo into dst_hi Example: r6 = (s8)r3 r6 maps to {ARM_R5, ARM_R4} and r3 is stacked ldr r4, [r11, #-16] // Load r3_lo to r6_lo lsl r4, r4, #24 // Sign extend r6_lo asr r4, r4, #24 // .. asr r5, r4, #31 // Sign extend r6_lo into r6_hi Case B.3: src is not stacked but dst is stacked: ------------------------------------------------ 1. Sign extend src_lo into tmp_lo according to offset. 2. Store tmp_lo into dst_lo. 3. Sign extend src_lo into tmp_hi. 4. Store tmp_hi to dst_hi. Example: r3 = (s8)r1 r3 is stacked and r1 maps to {ARM_R3, ARM_R2} lsl r6, r2, #24 // Sign extend r1_lo to tmp_lo asr r6, r6, #24 // .. str r6, [r11, #-16] // Store tmp_lo to r3_lo asr r7, r6, #31 // Sign extend tmp_lo to tmp_hi str r7, [r11, #-12] // Store tmp_hi to r3_hi Case B.4: Both src and dst are not stacked: ------------------------------------------- 1.

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 Overstreet1-18/+42
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 Overstreet1-15/+4
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.

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.

2024-04-20Revert "svcrdma: Add Write chunk WRs to the RPC's Send WR chain"Chuck Lever3-78/+26
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 Schimmel1-1/+1
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.
