2024-12-06cacheinfo: Allocate memory during CPU hotplug if not done from the primary CPURicardo Neri
Commit 5944ce092b97 ("arch_topology: Build cacheinfo from primary CPU") adds functionality that architectures can use to optionally allocate and build cacheinfo early during boot. Commit 6539cffa9495 ("cacheinfo: Add arch specific early level initializer") lets secondary CPUs correct (and reallocate memory) cacheinfo data if needed. If the early build functionality is not used and cacheinfo does not need correction, memory for cacheinfo is never allocated. x86 does not use the early build functionality. Consequently, during the cacheinfo CPU hotplug callback, last_level_cache_is_valid() attempts to dereference a NULL pointer: BUG: kernel NULL pointer dereference, address: 0000000000000100 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not present page PGD 0 P4D 0 Oops: 0000 [#1] PREEPMT SMP NOPTI CPU: 0 PID 19 Comm: cpuhp/0 Not tainted 6.4.0-rc2 #1 RIP: 0010: last_level_cache_is_valid+0x95/0xe0a Allocate memory for cacheinfo during the cacheinfo CPU hotplug callback if not done earlier. Moreover, before determining the validity of the last-level cache info, ensure that it has been allocated. Simply checking for non-zero cache_leaves() is not sufficient, as some architectures (e.g., Intel processors) have non-zero cache_leaves() before allocation. Dereferencing NULL cacheinfo can occur in update_per_cpu_data_slice_size(). This function iterates over all online CPUs. However, a CPU may have come online recently, but its cacheinfo may not have been allocated yet. While here, remove an unnecessary indentation in allocate_cache_info().

2024-12-05iio: magnetometer: yas530: use signed integer type for clamp limitsJakob Hauser
In the function yas537_measure() there is a clamp_val() with limits of -BIT(13) and BIT(13) - 1. The input clamp value h[] is of type s32. The BIT() is of type unsigned long integer due to its define in include/vdso/bits.h. The lower limit -BIT(13) is recognized as -8192 but expressed as an unsigned long integer. The size of an unsigned long integer differs between 32-bit and 64-bit architectures. Converting this to type s32 may lead to undesired behavior. Additionally, in the calculation lines h[0], h[1] and h[2] the unsigned long integer divisor BIT(13) causes an unsigned division, shifting the left-hand side of the equation back and forth, possibly ending up in large positive values instead of negative values on 32-bit architectures. To solve those two issues, declare a signed integer with a value of BIT(13). There is another omission in the clamp line: clamp_val() returns a value and it's going nowhere here. Self-assign it to h[i] to make use of the clamp macro. Finally, replace clamp_val() macro by clamp() because after changing the limits from type unsigned long integer to signed integer it's fine that way.

2024-12-05drm/v3d: Enable Performance Counters before clearing themMaíra Canal
On the Raspberry Pi 5, performance counters are not being cleared when `v3d_perfmon_start()` is called, even though we write to the CLR register. As a result, their values accumulate until they overflow. The expected behavior is for performance counters to reset to zero at the start of a job. When the job finishes and the perfmon is stopped, the counters should accurately reflect the values for that specific job. To ensure this behavior, the performance counters are now enabled before being cleared. This allows the CLR register to function as intended, zeroing the counter values when the job begins.

2024-12-05virtio-blk: don't keep queue frozen during system suspendMing Lei
Commit 4ce6e2db00de ("virtio-blk: Ensure no requests in virtqueues before deleting vqs.") replaces queue quiesce with queue freeze in virtio-blk's PM callbacks. And the motivation is to drain inflight IOs before suspending. block layer's queue freeze looks very handy, but it is also easy to cause deadlock, such as, any attempt to call into bio_queue_enter() may run into deadlock if the queue is frozen in current context. There are all kinds of ->suspend() called in suspend context, so keeping queue frozen in the whole suspend context isn't one good idea. And Marek reported lockdep warning[1] caused by virtio-blk's freeze queue in virtblk_freeze(). [1] https://lore.kernel.org/linux-block/ca16370e-d646-4eee-b9cc-87277c89c43c@samsung.com/ Given the motivation is to drain in-flight IOs, it can be done by calling freeze & unfreeze, meantime restore to previous behavior by keeping queue quiesced during suspend.

2024-12-05drm/dp_mst: Fix resetting msg rx state after topology removalImre Deak
If the MST topology is removed during the reception of an MST down reply or MST up request sideband message, the drm_dp_mst_topology_mgr::up_req_recv/down_rep_recv states could be reset from one thread via drm_dp_mst_topology_mgr_set_mst(false), racing with the reading/parsing of the message from another thread via drm_dp_mst_handle_down_rep() or drm_dp_mst_handle_up_req(). The race is possible since the reader/parser doesn't hold any lock while accessing the reception state. This in turn can lead to a memory corruption in the reader/parser as described by commit bd2fccac61b4 ("drm/dp_mst: Fix MST sideband message body length check"). Fix the above by resetting the message reception state if needed before reading/parsing a message. Another solution would be to hold the drm_dp_mst_topology_mgr::lock for the whole duration of the message reception/parsing in drm_dp_mst_handle_down_rep() and drm_dp_mst_handle_up_req(), however this would require a bigger change. Since the fix is also needed for stable, opting for the simpler solution in this patch.

2024-12-04net/mlx5e: Remove workaround to avoid syndrome for internal portJianbo Liu
Previously a workaround was added to avoid syndrome 0xcdb051. It is triggered when offload a rule with tunnel encapsulation, and forwarding to another table, but not matching on the internal port in firmware steering mode. The original workaround skips internal tunnel port logic, which is not correct as not all cases are considered. As an example, if vlan is configured on the uplink port, traffic can't pass because vlan header is not added with this workaround. Besides, there is no such issue for software steering. So, this patch removes that, and returns error directly if trying to offload such rule for firmware steering.

2024-12-04net/mlx5e: SD, Use correct mdev to build channel paramTariq Toukan
In a multi-PF netdev, each traffic channel creates its own resources against a specific PF. In the cited commit, where this support was added, the channel_param logic was mistakenly kept unchanged, so it always used the primary PF which is found at priv->mdev. In this patch we fix this by moving the logic to be per-channel, and passing the correct mdev instance. This bug happened to be usually harmless, as the resulting cparam structures would be the same for all channels, due to identical FW logic and decisions. However, in some use cases, like fwreset, this gets broken. This could lead to different symptoms.

2024-12-04bnxt_en: handle tpa_info in queue API implementationDavid Wei
Commit 7ed816be35ab ("eth: bnxt: use page pool for head frags") added a page pool for header frags, which may be distinct from the existing pool for the aggregation ring. Prior to this change, frags used in the TPA ring rx_tpa were allocated from system memory e.g. napi_alloc_frag() meaning their lifetimes were not associated with a page pool. They can be returned at any time and so the queue API did not alloc or free rx_tpa. But now frags come from a separate head_pool which may be different to page_pool. Without allocating and freeing rx_tpa, frags allocated from the old head_pool may be returned to a different new head_pool which causes a mismatch between the pp hold/release count. Fix this problem by properly freeing and allocating rx_tpa in the queue API implementation.

There are 2 pairs of operations: * bnxt_alloc_one_tpa_info() * bnxt_free_one_tpa_info() These alloc/free the tpa_info array itself. * bnxt_alloc_one_tpa_info_data() * bnxt_free_one_tpa_info_data() These alloc/free the frags stored in tpa_info array.

2024-12-04mlxsw: spectrum_acl_flex_keys: Use correct key block on Spectrum-4Ido Schimmel
The driver is currently using an ACL key block that is not supported by Spectrum-4. This works because the driver is only using a single field from this key block which is located in the same offset in the equivalent Spectrum-4 key block. The issue was discovered when the firmware started rejecting the use of the unsupported key block. The change has been reverted to avoid breaking users that only update their firmware. Nonetheless, fix the issue by using the correct key block.

2024-12-04scsi: scsi_debug: Fix hrtimer support for ndelayJohn Garry
Since commit 771f712ba5b0 ("scsi: scsi_debug: Fix cmd duration calculation"), ns_from_boot value is only evaluated in schedule_resp() for polled requests. However, ns_from_boot is also required for hrtimer support for when ndelay is less than INCLUSIVE_TIMING_MAX_NS, so fix up the logic to decide when to evaluate ns_from_boot.
