2024-09-06drm/amd/display: Avoid race between dcn10_set_drr() and dc_state_destruct()Tobias Jakobi
dc_state_destruct() nulls the resource context of the DC state. The pipe context passed to dcn10_set_drr() is a member of this resource context. If dc_state_destruct() is called parallel to the IRQ processing (which calls dcn10_set_drr() at some point), we can end up using already nulled function callback fields of struct stream_resource. The logic in dcn10_set_drr() already tries to avoid this, by checking tg against NULL. But if the nulling happens exactly after the NULL check and before the next access, then we get a race. Avoid this by copying tg first to a local variable, and then use this variable for all the operations. This should work, as long as nobody frees the resource pool where the timing generators live.

2024-09-06drm/amd/display: Add missing kdoc entry for 'bs_coeffs_updated' in ↵Srinivasan Shanmugam
dpp401_dscl_program_isharp This commit addresses a missing kdoc for the 'bs_coeffs_updated' parameter in the 'dpp401_dscl_program_isharp' function. The 'bs_coeffs_updated' is a flag indicating whether the Blur and Scale Coefficients have been updated. The 'dpp401_dscl_program_isharp' function is responsible for programming the isharp, which includes setting the isharp filter, noise gain, and blur and scale coefficients. If the 'bs_coeffs_updated' flag is set to true, the function updates the blur and scale coefficients. Fixes the below with gcc W=1: drivers/gpu/drm/amd/amdgpu/../display/dc/dpp/dcn401/dcn401_dpp_dscl.c:961: warning: Function parameter or struct member 'bs_coeffs_updated' not described in 'dpp401_dscl_program_isharp' Cc: Tom Chung <chiahsuan.chung@amd.com> Cc: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Cc: Roman Li <roman.li@amd.com> Cc: Alex Hung <alex.hung@amd.com> Cc: Aurabindo Pillai <aurabindo.pillai@amd.com> Cc: Harry Wentland <harry.wentland@amd.com> Cc: Hamza Mahfooz <hamza.mahfooz@amd.com> Signed-off-by: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com> Suggested-by: Tom Chung <chiahsuan.chung@amd.com> Reviewed-by: Tom Chung <chiahsuan.chung@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2024-09-06libfs: fix get_stashed_dentry()Christian Brauner
get_stashed_dentry() tries to optimistically retrieve a stashed dentry from a provided location. It needs to ensure to hold rcu lock before it dereference the stashed location to prevent UAF issues. Use rcu_dereference() instead of READ_ONCE() it's effectively equivalent with some lockdep bells and whistles and it communicates clearly that this expects rcu protection.

Flow for creating Tx topology is the same as for VF port representors, but the devlink port is stored in different place (sf->devlink_port). When creating VF devlink lock isn't taken, when creating subfunction it is. Setting Tx topology function needs to take this lock, check if it was taken before to not do it twice.

2024-09-06ice: add basic devlink subfunctions supportPiotr Raczynski
Implement devlink port handlers responsible for ethernet type devlink subfunctions. Create subfunction devlink port and setup all resources needed for a subfunction netdev to operate. Configure new VSI for each new subfunction, initialize and configure interrupts and Tx/Rx resources. Set correct MAC filters and create new netdev. For now, subfunction is limited to only one Tx/Rx queue pair. Only allocate new subfunction VSI with devlink port new command. Allocate and free subfunction MSIX interrupt vectors using new API calls with pci_msix_alloc_irq_at and pci_msix_free_irq. Support both automatic and manual subfunction numbers. If no subfunction number is provided, use xa_alloc to pick a number automatically. This will find the first free index and use that as the number. This reduces burden on users in the simple case where a specific number is not required. It may also be slightly faster to check that a number exists since xarray lookup should be faster than a linear scan of the dyn_ports xarray.

2024-09-06md: Add new_level sysfs interfaceXiao Ni
Now reshape supports two ways: with backup file or without backup file. For the situation without backup file, it needs to change data offset. It doesn't need systemd service mdadm-grow-continue. So it can finish the reshape job in one process environment. It can know the new level from mdadm --grow command and can change to new level after reshape finishes. For the situation with backup file, it needs systemd service mdadm-grow-continue to monitor reshape progress. So there are two process envolved. One is mdadm --grow command whick kicks off reshape and wakes up mdadm-grow-continue service. The second process is the service, which doesn't know the new level from the first process. In kernel space mddev->new_level is used to record the new level when doing reshape. This patch adds a new interface to help mdadm update new_level and sync it to metadata. Then mdadm-grow-continue can read the right new_level. Commit log revised by Song Liu. Please refer to the link for more details.
