2024-10-14drm/msm/dsi: fix 32-bit signed integer extension in pclk_rate calculationJonathan Marek
When (mode->clock * 1000) is larger than (1<<31), int to unsigned long conversion will sign extend the int to 64 bits and the pclk_rate value will be incorrect. Fix this by making the result of the multiplication unsigned. Note that above (1<<32) would still be broken and require more changes, but its unlikely anyone will need that anytime soon.

2024-10-14drm/msm/dpu: move CRTC resource assignment to dpu_encoder_virt_atomic_checkDmitry Baryshkov
Historically CRTC resources (LMs and CTLs) were assigned in dpu_crtc_atomic_begin(). The commit 9222cdd27e82 ("drm/msm/dpu: move hw resource tracking to crtc state") simply moved resources to struct dpu_crtc_state, without changing the code sequence. Later on the commit b107603b4ad0 ("drm/msm/dpu: map mixer/ctl hw blocks in encoder modeset") rearanged the code, but still kept the cstate->num_mixers assignment to happen during commit phase. This makes dpu_crtc_state inconsistent between consequent atomic_check() calls. Move CRTC resource assignment to happen at the end of dpu_encoder_virt_atomic_check().

2024-10-14drm/msm/dpu: make sure phys resources are properly initializedDmitry Baryshkov
The commit b954fa6baaca ("drm/msm/dpu: Refactor rm iterator") removed zero-init of the hw_ctl array, but didn't change the error condition, that checked for hw_ctl[i] being NULL. At the same time because of the early returns in case of an error dpu_encoder_phys might be left with the resources assigned in the previous state. Rework assigning of hw_pp / hw_ctl to the dpu_encoder_phys in order to make sure they are always set correctly.

2024-10-14ring-buffer: Fix refcount setting of boot mapped buffersSteven Rostedt
A ring buffer which has its buffered mapped at boot up to fixed memory should not be freed. Other buffers can be. The ref counting setup was wrong for both. It made the not mapped buffers ref count have zero, and the boot mapped buffer a ref count of 1. But an normally allocated buffer should be 1, where it can be removed. Keep the ref count of a normal boot buffer with its setup ref count (do not decrement it), and increment the fixed memory boot mapped buffer's ref count.

2024-10-14bcachefs: Fix sysfs warning in fstests generic/730,731Kent Overstreet
sysfs warns if we're removing a symlink from a directory that's no longer in sysfs; this is triggered by fstests generic/730, which simulates hot removal of a block device. This patch is however not a correct fix, since checking kobj->state_in_sysfs on a kobj owned by another subsystem is racy. A better fix would be to add the appropriate check to sysfs_remove_link() - and sysfs_create_link() as well. But kobject_add_internal()/kobject_del() do not as of today have locking that would support that. Note that the block/holder.c code appears to be subject to this race as well.

2024-10-13bcachefs: Handle race between stripe reuse, invalidate_stripe_to_devKent Overstreet
When creating a new stripe, we may reuse an existing stripe that has some empty and some nonempty blocks. Generally, the existing stripe won't change underneath us - except for block sector counts, which we copy to the new key in ec_stripe_key_update. But the device removal path can now invalidate stripe pointers to a device, and that can race with stripe reuse. Change ec_stripe_key_update() to check for and resolve this inconsistency.

2024-10-11RDMA/bnxt_re: Fix the GID table lengthKalesh AP
GID table length is reported by FW. The gid index which is passed to the driver during modify_qp/create_ah is restricted by the sgid_index field of struct ib_global_route. sgid_index is u8 and the max sgid possible is 256. Each GID entry in HW will have 2 GID entries in the kernel gid table. So we can support twice the gid table size reported by FW. Also, restrict the max GID to 256 also.

There will be a single PDE page address (contiguous pages in the case of > PAGE_SIZE), but, current logic assumes multiple pages, leading to invalid memory access after 256K PBL entries in the PDE.

2024-10-11RDMA/bnxt_re: Change the sequence of updating the CQ toggle valueChandramohan Akula
Currently the CQ toggle value in the shared page (read by the userlib) is updated as part of the cqn_handler. There is a potential race of application calling the CQ ARM doorbell immediately and using the old toggle value. Change the sequence of updating CQ toggle value to update in the bnxt_qplib_service_nq function immediately after reading the toggle value to be in sync with the HW updated value.

2024-10-11RDMA/bnxt_re: Avoid CPU lockups due fifo occupancy check loopSelvin Xavier
Driver waits indefinitely for the fifo occupancy to go below a threshold as soon as the pacing interrupt is received. This can cause soft lockup on one of the processors, if the rate of DB is very high. Add a loop count for FPGA and exit the __wait_for_fifo_occupancy_below_th if the loop is taking more time. Pacing will be continuing until the occupancy is below the threshold. This is ensured by the checks in bnxt_re_pacing_timer_exp and further scheduling the work for pacing based on the fifo occupancy.
