f95b8ea Javier Martinez Canillas 07 February 2023, 10:22:54 UTC Revert "venus: firmware: Correct non-pix start and end addresses" This reverts commit a837e5161cff, which broke probing of the venus driver, at least on the SC7180 SoC HP X2 Chromebook: qcom-venus aa00000.video-codec: Adding to iommu group 11 qcom-venus aa00000.video-codec: non legacy binding qcom-venus aa00000.video-codec: failed to reset venus core qcom-venus: probe of aa00000.video-codec failed with error -110 Matthias Kaehlcke also reported that the same change caused a regression in SC7180 and sc7280, that prevents AOSS from entering sleep mode during system suspend. So let's revert this commit for now to fix both issues.

7b50567 Arnd Bergmann 07 February 2023, 16:13:12 UTC media: i2c: imx290: fix conditional function defintions The runtime suspend/resume functions are only referenced from the dev_pm_ops, but they use the old SET_RUNTIME_PM_OPS() helper that requires a __maybe_unused annotation to avoid a warning: drivers/media/i2c/imx290.c:1082:12: error: unused function 'imx290_runtime_resume' [-Werror,-Wunused-function] static int imx290_runtime_resume(struct device *dev) ^ drivers/media/i2c/imx290.c:1090:12: error: unused function 'imx290_runtime_suspend' [-Werror,-Wunused-function] static int imx290_runtime_suspend(struct device *dev) ^ Convert this to the new RUNTIME_PM_OPS() helper that so this is not required. To improve this further, also use the pm_ptr() helper that lets the dev_pm_ops get dropped entirely when CONFIG_PM is disabled. A related mistake happened in the of_match_ptr() macro here, which like SET_RUNTIME_PM_OPS() requires the match table to be marked as __maybe_unused, though I could not reproduce building this without CONFIG_OF. Remove the of_match_ptr() here as there is no point in dropping the match table in configurations without CONFIG_OF.

e3271a5 Hans de Goede 30 March 2023, 19:46:44 UTC platform/x86: ideapad-laptop: Stop sending KEY_TOUCHPAD_TOGGLE Commit 5829f8a897e4 ("platform/x86: ideapad-laptop: Send KEY_TOUCHPAD_TOGGLE on some models") made ideapad-laptop send KEY_TOUCHPAD_TOGGLE when we receive an ACPI notify with VPC event bit 5 set and the touchpad-state has not been changed by the EC itself already. This was done under the assumption that this would be good to do to make the touchpad-toggle hotkey work on newer models where the EC does not toggle the touchpad on/off itself (because it is not routed through the PS/2 controller, but uses I2C). But it turns out that at least some models, e.g. the Yoga 7-15ITL5 the EC triggers an ACPI notify with VPC event bit 5 set on resume, which would now cause a spurious KEY_TOUCHPAD_TOGGLE on resume to which the desktop environment responds by disabling the touchpad in software, breaking the touchpad (until manually re-enabled) on resume. It was never confirmed that sending KEY_TOUCHPAD_TOGGLE actually improves things on new models and at least some new models like the Yoga 7-15ITL5 don't have a touchpad on/off toggle hotkey at all, while still sending ACPI notify events with VPC event bit 5 set. So it seems best to revert the change to send KEY_TOUCHPAD_TOGGLE when receiving an ACPI notify events with VPC event bit 5 and the touchpad state as reported by the EC has not changed. Note this is not a full revert the code to cache the last EC touchpad state is kept to avoid sending spurious KEY_TOUCHPAD_ON / _OFF events on resume.

Two methods were considered to fix the issue. - Use the dmar_global_lock to replace the RCU read lock when going through the drhd list. But it triggers a lockdep warning. - Use the cpuhp_setup_state_multi() to set up a dedicated state for each IOMMU PMU. The lock can be avoided. The latter method is implemented in this patch.

But the case where duplicate bios are issued must call it too. Otherwise the bio won't be split and resubmitted (via recursion through block core back to DM) to submit the later portions of a bio (which may map to an entirely different target). For example, when discarding an entire DM striped device with the following DM table: vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048 vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048 Before (broken, discards the first striped target's devices twice): device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872 device-mapper: striped: target_stripe=0, bdev=7:0, start=2049 len=22528 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=22528 After (works as expected): device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872 device-mapper: striped: target_stripe=0, bdev=7:2, start=2048 len=22528 device-mapper: striped: target_stripe=1, bdev=7:3, start=2048 len=22528 Fixes: 7dd76d1feec70 ("dm: improve bio splitting and associated IO accounting") Cc: stable@vger.kernel.org Reported-by: Orange Kao <orange@aiven.io> Signed-off-by: Mike Snitzer <snitzer@kernel.org> 30 March 2023, 19:54:32 UTC
f7b58a6 Mike Snitzer 30 March 2023, 18:56:38 UTC dm: fix improper splitting for abnormal bios "Abnormal" bios include discards, write zeroes and secure erase. By no longer passing the calculated 'len' pointer, commit 7dd06a2548b2 ("dm: allow dm_accept_partial_bio() for dm_io without duplicate bios") took a senseless approach to disallowing dm_accept_partial_bio() from working for duplicate bios processed using __send_duplicate_bios(). It inadvertently and incorrectly stopped the use of 'len' when initializing a target's io (in alloc_tio). As such the resulting tio could address more area of a device than it should.

This happens because when mvneta_cleanup_txqs() is called in the mvneta_stop() path, we leave pointers in the structure that have been freed. Then on mvneta_open(), we call mvneta_setup_txqs(), which starts allocating memory. On memory allocation failure, mvneta_cleanup_txqs() will walk all the queues freeing any non-NULL pointers - which includes pointers that were previously freed in mvneta_stop(). Fix this by setting these pointers to NULL to prevent double-freeing of the same memory.

64fdc5f Vladimir Oltean 29 March 2023, 15:18:21 UTC net: dsa: sync unicast and multicast addresses for VLAN filters too If certain conditions are met, DSA can install all necessary MAC addresses on the CPU ports as FDB entries and disable flooding towards the CPU (we call this RX filtering). There is one corner case where this does not work. ip link add br0 type bridge vlan_filtering 1 && ip link set br0 up ip link set swp0 master br0 && ip link set swp0 up ip link add link swp0 name swp0.100 type vlan id 100 ip link set swp0.100 up && ip addr add 192.168.100.1/24 dev swp0.100 Traffic through swp0.100 is broken, because the bridge turns on VLAN filtering in the swp0 port (causing RX packets to be classified to the FDB database corresponding to the VID from their 802.1Q header), and although the 8021q module does call dev_uc_add() towards the real device, that API is VLAN-unaware, so it only contains the MAC address, not the VID; and DSA's current implementation of ndo_set_rx_mode() is only for VID 0 (corresponding to FDB entries which are installed in an FDB database which is only hit when the port is VLAN-unaware). It's interesting to understand why the bridge does not turn on IFF_PROMISC for its swp0 bridge port, and it may appear at first glance that this is a regression caused by the logic in commit 2796d0c648c9 ("bridge: Automatically manage port promiscuous mode."). After all, a bridge port needs to have IFF_PROMISC by its very nature - it needs to receive and forward frames with a MAC DA different from the bridge ports' MAC addresses. While that may be true, when the bridge is VLAN-aware *and* it has a single port, there is no real reason to enable promiscuity even if that is an automatic port, with flooding and learning (there is nowhere for packets to go except to the BR_FDB_LOCAL entries), and this is how the corner case appears. Adding a second automatic interface to the bridge would make swp0 promisc as well, and would mask the corner case. Given the dev_uc_add() / ndo_set_rx_mode() API is what it is (it doesn't pass a VLAN ID), the only way to address that problem is to install host FDB entries for the cartesian product of RX filtering MAC addresses and VLAN RX filters.

This can easily be fixed by checking to see if the mask has already been allocated in the init routine. When max_idle is specified as a module parameter a panic will occur. The problem is that the idle_injection_cpu_mask is not allocated until the module init routine executes. This can easily be fixed by allocating the cpumask if it's not already allocated.

6f5d828 Paolo Abeni 30 March 2023, 08:47:51 UTC Merge branch 'fix-header-length-on-skb-merging' Arseniy Krasnov says: ==================== fix header length on skb merging this patchset fixes appending newly arrived skbuff to the last skbuff of the socket's queue during rx path. Problem fires when we are trying to append data to skbuff which was already processed in dequeue callback at least once. Dequeue callback calls function 'skb_pull()' which changes 'skb->len'. In current implementation 'skb->len' is used to update length in header of last skbuff after new data was copied to it. This is bug, because value in header is used to calculate 'rx_bytes'/'fwd_cnt' and thus must be constant during skbuff lifetime. Here is example, we have two skbuffs: skb0 with length 10 and skb1 with length 4. 1) skb0 arrives, hdr->len == skb->len == 10, rx_bytes == 10 2) Read 3 bytes from skb0, skb->len == 7, hdr->len == 10, rx_bytes == 10 3) skb1 arrives, hdr->len == skb->len == 4, rx_bytes == 14 4) Append skb1 to skb0, skb0 now has skb->len == 11, hdr->len == 11. But value of 11 in header is invalid. 5) Read whole skb0, update rx_bytes by 11 from skb0's header. 6) At this moment rx_bytes == 3, but socket's queue is empty. This bug starts to fire since: commit 077706165717 ("virtio/vsock: don't use skbuff state to account credit") In fact, it presents before, but didn't triggered due to a little bit buggy implementation of credit calculation logic.

However the calculation is done incorrectly. For 4KB pages, this total size is currently always more than one page, and as a result, the calculation produces a positive (though incorrect) total size. The code still works in this case; we just end up with fewer DMA pool entries than we intended. Bjorn Andersson tested booting a kernel with 16KB pages, and hit a null pointer derereference in sg_alloc_append_table_from_pages(), descending from gsi_trans_pool_init_dma(). The cause of this was that a 16KB total size was going to be allocated, and with 16KB pages the order of that allocation is 0. The total_size calculation yielded 0, which eventually led to the crash. Correcting the total_size calculation fixes the problem.

In this case reported: we failed to allocate one of the io queues, and as we start releasing the queues that we already allocated, we get a UAF [1] from the io_work which is running before it should really. Fix this by setting the socket ops callbacks only before we start the queue, so that we can't accidentally schedule the io_work in the initialization phase before the queue started. While we are at it, rename nvme_tcp_restore_sock_calls to pair with nvme_tcp_setup_sock_ops.

4622f15 Palmer Dabbelt 29 March 2023, 18:48:41 UTC Merge patch series "RISC-V: Fixes for riscv_has_extension[un]likely()'s alternative dependency" Conor Dooley <conor.dooley@microchip.com> says: Here's my attempt at fixing both the use of an FPU on XIP kernels and the issue that Jason ran into where CONFIG_FPU, which needs the alternatives frame work for has_fpu() checks, could be enabled without the alternatives actually being present. For the former, a "slow" fallback that does not use alternatives is added to riscv_has_extension_[un]likely() that can be used with XIP. Obviously, we want to make use of Jisheng's alternatives based approach where possible, so any users of riscv_has_extension_[un]likely() will want to make sure that they select RISCV_ALTERNATIVE. If they don't however, they'll hit the fallback path which (should, sparing a silly mistake from me!) behave in the same way, thus succeeding silently. Sounds like a To prevent "depends on !XIP_KERNEL; select RISCV_ALTERNATIVE" spreading like the plague through the various places that want to check for the presence of extensions, and sidestep the potential silent "success" mentioned above, all users RISCV_ALTERNATIVE are converted from selects to dependencies, with the option being selected for all !XIP_KERNEL builds. I know that the VDSO was a key place that Jisheng wanted to use the new helper rather than static branches, and I think the fallback path should not cause issues there. See the thread at [1] for the prior discussion. 1 - https://lore.kernel.org/linux-riscv/20230128172856.3814-1-jszhang@kernel.org/T/#m21390d570997145d31dd8bb95002fd61f99c6573 [Palmer: merging in the fixes as a branch as there's some features that depend on it.] * b4-shazam-merge: RISC-V: always select RISCV_ALTERNATIVE for non-xip kernels RISC-V: add non-alternative fallback for riscv_has_extension_[un]likely() Link: https://lore.kernel.org/r/20230324100538.3514663-1-conor.dooley@microchip.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com> 29 March 2023, 19:23:00 UTC
1ee7fc3 Conor Dooley 24 March 2023, 10:05:39 UTC RISC-V: always select RISCV_ALTERNATIVE for non-xip kernels When moving switch_to's has_fpu() over to using riscv_has_extension_likely() rather than static branches, the FPU code gained a dependency on the alternatives framework. That dependency has now been removed, as riscv_has_extension_ikely() now contains a fallback path, using __riscv_isa_extension_available(), but if CONFIG_RISCV_ALTERNATIVE isn't selected when CONFIG_FPU is, has_fpu() checks will not benefit from the "fast path" that the alternatives framework provides. We want to ensure that alternatives are available whenever riscv_has_extension_[un]likely() is used, rather than silently falling back to the slow path, but rather than rely on selecting RISCV_ALTERNATIVE in the myriad of locations that may use riscv_has_extension_[un]likely(), select it (almost) always instead by adding it to the main RISCV config entry. xip kernels cannot make use of the alternatives framework, so it is not enabled for those configurations, although this is the status quo. All current sites that select RISCV_ALTERNATIVE are converted to dependencies on the option instead. The explicit dependencies on !XIP_KERNEL can be dropped, as RISCV_ALTERNATIVE is not user selectable.

When alternatives support is not present, fall back to using __riscv_isa_extension_available() in riscv_has_extension_[un]likely() instead stead, which handily takes the same argument, so that kernels that do not support alternatives can accurately report the presence of FPU support.

The current VAS implementation also supports only with Radix page tables. Whereas in dedicated processor mode, pseries_vas_notifier() is registered only if the copy/paste feature is enabled. So instead of displaying HCALL error messages, update VAS capabilities if the copy/paste feature is available.

07b3af4 Felix Fietkau 24 March 2023, 14:04:04 UTC net: ethernet: mtk_eth_soc: fix tx throughput regression with direct 1G links Using the QDMA tx scheduler to throttle tx to line speed works fine for switch ports, but apparently caused a regression on non-switch ports. Based on a number of tests, it seems that this throttling can be safely dropped without re-introducing the issues on switch ports that the tx scheduling changes resolved.

2280d42 Filipe Manana 28 March 2023, 09:45:20 UTC btrfs: ignore fiemap path cache when there are multiple paths for a node During fiemap, when walking backreferences to determine if a b+tree node/leaf is shared, we may find a tree block (leaf or node) for which two parents were added to the references ulist. This happens if we get for example one direct ref (shared tree block ref) and one indirect ref (non-shared tree block ref) for the tree block at the current level, which can happen during relocation. In that case the fiemap path cache can not be used since it's meant for a single path, with one tree block at each possible level, so having multiple references for a tree block at any level may result in getting the level counter exceed BTRFS_MAX_LEVEL and eventually trigger the warning: WARN_ON_ONCE(level >= BTRFS_MAX_LEVEL) at lookup_backref_shared_cache() and at store_backref_shared_cache(). This is harmless since the code ignores any level >= BTRFS_MAX_LEVEL, the warning is there just to catch any unexpected case like the one described above. However if a user finds this it may be scary and get reported. So just ignore the path cache once we find a tree block for which there are more than one reference, which is the less common case, and update the cache with the sharedness check result for all levels below the level for which we found multiple references.
