To address this, move the lock to struct\nstmmac_priv. We also need to reacquire the mutex lock when doing\nthis initialization.\n\nDEBUG_LOCKS_WARN_ON(lock->magic != lock)\nWARNING: CPU: 3 PID: 505 at kernel/locking/mutex.c:587 __mutex_lock+0xd84/0x1068\n Modules linked in:\n CPU: 3 PID: 505 Comm: tc Not tainted 6.9.0-rc6-00053-g0106679839f7-dirty #29\n Hardware name: NXP i.MX8MPlus EVK board (DT)\n pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--)\n pc : __mutex_lock+0xd84/0x1068\n lr : __mutex_lock+0xd84/0x1068\n sp : ffffffc0864e3570\n x29: ffffffc0864e3570 x28: ffffffc0817bdc78 x27: 0000000000000003\n x26: ffffff80c54f1808 x25: ffffff80c9164080 x24: ffffffc080d723ac\n x23: 0000000000000000 x22: 0000000000000002 x21: 0000000000000000\n x20: 0000000000000000 x19: ffffffc083bc3000 x18: ffffffffffffffff\n x17: ffffffc08117b080 x16: 0000000000000002 x15: ffffff80d2d40000\n x14: 00000000000002da x13: ffffff80d2d404b8 x12: ffffffc082b5a5c8\n x11: ffffffc082bca680 x10: ffffffc082bb2640 x9 : ffffffc082bb2698\n x8 : 0000000000017fe8 x7 : c0000000ffffefff x6 : 0000000000000001\n x5 : ffffff8178fe0d48 x4 : 0000000000000000 x3 : 0000000000000027\n x2 : ffffff8178fe0d50 x1 : 0000000000000000 x0 : 0000000000000000\n Call trace:\n  __mutex_lock+0xd84/0x1068\n  mutex_lock_nested+0x28/0x34\n  tc_setup_taprio+0x118/0x68c\n  stmmac_setup_tc+0x50/0xf0\n  taprio_change+0x868/0xc9c\n\n## Affected\n\n- `Linux >= b2aae654a4794ef898ad33a179f341eb610f6b85 < 4fe005dca04cf906cc699efac49a24838ab4be0b`\n- `Linux >= b2aae654a4794ef898ad33a179f341eb610f6b85 < b538fefeb1026aad9dcdcbb410c42b56dff8aae9`\n- `Linux >= b2aae654a4794ef898ad33a179f341eb610f6b85 < 487f9030b1ef34bab123f2df2a4ccbe01ba84416`\n- `Linux >= b2aae654a4794ef898ad33a179f341eb610f6b85 < 6f476aff2d8da1a189621c4c16a76a6c534e4312`\n- `Linux >= b2aae654a4794ef898ad33a179f341eb610f6b85 < 36ac9e7f2e5786bd37c5cd91132e1f39c29b8197`\n- `Linux b2091d47a14e8e6b3f03d792c1b25255d60b3219`\n- `Linux 5ce4cc16d47186f0b76254e6f27beea25bafc1d9`\n- `Linux >= 5.10.62 < 5.11`\n- `Linux >= 5.13.14 < 5.14`\n- `Linux 5.14`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
