Title
net/mlx5: Fix missing lock on sync reset reload
Summary
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix missing lock on sync reset reload On sync reset reload work, when remote host updates devlink on reload actions performed on that host, it misses taking devlink lock before calling devlink_remote_reload_actions_performed() which results in triggering lock assert like the following: WARNING: CPU: 4 PID: 1164 at net/devlink/core.c:261 devl_assert_locked+0x3e/0x50 … CPU: 4 PID: 1164 Comm: kworker/u96:6 Tainted: G S W 6.10.0-rc2+ #116 Hardware name: Supermicro SYS-2028TP-DECTR/X10DRT-PT, BIOS 2.0 12/18/2015 Workqueue: mlx5_fw_reset_events mlx5_sync_reset_reload_work [mlx5_core] RIP: 0010:devl_assert_locked+0x3e/0x50 … Call Trace: <TASK> ? __warn+0xa4/0x210 ? devl_assert_locked+0x3e/0x50 ? report_bug+0x160/0x280 ? handle_bug+0x3f/0x80 ? exc_invalid_op+0x17/0x40 ? asm_exc_invalid_op+0x1a/0x20 ? devl_assert_locked+0x3e/0x50 devlink_notify+0x88/0x2b0 ? mlx5_attach_device+0x20c/0x230 [mlx5_core] ? __pfx_devlink_notify+0x10/0x10 ? process_one_work+0x4b6/0xbb0 process_one_work+0x4b6/0xbb0 […]
