2024-07-24vfs: handle __wait_on_freeing_inode() and evict() raceMateusz Guzik
Lockless hash lookup can find and lock the inode after it gets the I_FREEING flag set, at which point it blocks waiting for teardown in evict() to finish. However, the flag is still set even after evict() wakes up all waiters. This results in a race where if the inode lock is taken late enough, it can happen after both hash removal and wakeups, meaning there is nobody to wake the racing thread up. This worked prior to RCU-based lookup because the entire ordeal was synchronized with the inode hash lock. Since unhashing requires the inode lock, we can safely check whether it happened after acquiring it.

2024-07-23cifs: mount with "unix" mount option for SMB1 incorrectly handledSteve French
Although by default we negotiate CIFS Unix Extensions for SMB1 mounts to Samba (and they work if the user does not specify "unix" or "posix" or "linux" on mount), and we do properly handle when a user turns them off with "nounix" mount parm. But with the changes to the mount API we broke cases where the user explicitly specifies the "unix" option (or equivalently "linux" or "posix") on mount with vers=1.0 to Samba or other servers which support the CIFS Unix Extensions. "mount error(95): Operation not supported" and logged: "CIFS: VFS: Check vers= mount option. SMB3.11 disabled but required for POSIX extensions" even though CIFS Unix Extensions are supported for vers=1.0 This patch fixes the case where the user specifies both "unix" (or equivalently "posix" or "linux") and "vers=1.0" on mount to a server which supports the CIFS Unix Extensions.

This commit addresses a potential null pointer dereference issue in the `dcn30_init_hw` function. The issue could occur when `dc->clk_mgr` or `dc->clk_mgr->funcs` is null. The fix adds a check to ensure `dc->clk_mgr` and `dc->clk_mgr->funcs` is not null before accessing its functions. This prevents a potential null pointer dereference.

2024-07-23drm/amd/display: Fix index out of bounds in DCN30 color transformationSrinivasan Shanmugam
This commit addresses a potential index out of bounds issue in the `cm3_helper_translate_curve_to_hw_format` function in the DCN30 color management module. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS). The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds, the function returns false to indicate an error. drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:180 cm3_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.red' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:181 cm3_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.green' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:182 cm3_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.blue' 1025 <= s32max 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> Reviewed-by: Tom Chung <chiahsuan.chung@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2024-07-23drm/amd/display: Implement bounds check for stream encoder creation in DCN401Srinivasan Shanmugam
'stream_enc_regs' array is an array of dcn10_stream_enc_registers structures. The array is initialized with four elements, corresponding to the four calls to stream_enc_regs() in the array initializer. This means that valid indices for this array are 0, 1, 2, and 3. The error message 'stream_enc_regs' 4 <= 5 below, is indicating that there is an attempt to access this array with an index of 5, which is out of bounds. This could lead to undefined behavior Here, eng_id is used as an index to access the stream_enc_regs array. If eng_id is 5, this would result in an out-of-bounds access on the stream_enc_regs array.
