This is caused\nfrom the driver *only* calling the ice_vsi_free_q_vectors() function by\nitself, when it is suspending. Since commit b3e7b3a6ee92 (\"ice: prevent\nNULL pointer deref during reload\") the driver has zeroed out\nnum_q_vectors, and only restored it in ice_vsi_cfg_def().\n\nThis further causes the ice_rebuild() function to allocate a zero length\nbuffer, after which num_q_vectors is updated, and then the new value of\nnum_q_vectors is used to index into the zero length buffer, which\ncorrupts memory.\n\nThe fix entails making sure all the code referencing num_q_vectors only\ndoes so after it has been reset via ice_vsi_cfg_def().\n\nI didn't perform a full bisect, but I was able to test against 6.1.77\nkernel and that ice driver works fine for suspend/resume with no panic,\nso sometime since then, this problem was introduced.\n\nAlso clean up an un-needed init of a local variable in the function\nbeing modified.\n\nPANIC from 6.8.0-rc1:\n\n[1026674.915596] PM: suspend exit\n[1026675.664697] ice 0000:17:00.1: PTP reset successful\n[1026675.664707] ice 0000:17:00.1: 2755 msecs passed between update to cached PHC time\n[1026675.667660] ice 0000:b1:00.0: PTP reset successful\n[1026675.675944] ice 0000:b1:00.0: 2832 msecs passed between update to cached PHC time\n[1026677.137733] ixgbe 0000:31:00.0 ens787: NIC Link is Up 1 Gbps, Flow Control: None\n[1026677.190201] BUG: kernel NULL pointer dereference, address: 0000000000000010\n[1026677.192753] ice 0000:17:00.0: PTP reset successful\n[1026677.192764] ice 0000:17:00.0: 4548 msecs passed between update to cached PHC time\n[1026677.197928] #PF: supervisor read access in kernel mode\n[1026677.197933] #PF: error_code(0x0000) - not-present page\n[1026677.197937] PGD 1557a7067 P4D 0\n[1026677.212133] ice 0000:b1:00.1: PTP reset successful\n[1026677.212143] ice 0000:b1:00.1: 4344 msecs passed between update to cached PHC time\n[1026677.212575]\n[1026677.243142] Oops: 0000 [#1] PREEMPT SMP NOPTI\n[1026677.247918] CPU: 23 PID: 42790 Comm: kworker/23:0 Kdump: loaded Tainted: G W 6.8.0-rc1+ #1\n[1026677.257989] Hardware name: Intel Corporation M50CYP2SBSTD/M50CYP2SBSTD, BIOS SE5C620.86B.01.01.0005.2202160810 02/16/2022\n[1026677.269367] Workqueue: ice ice_service_task [ice]\n[1026677.274592] RIP: 0010:ice_vsi_rebuild_set_coalesce+0x130/0x1e0 [ice]\n[1026677.281421] Code: 0f 84 3a ff ff ff 41 0f b7 74 ec 02 66 89 b0 22 02 00 00 81 e6 ff 1f 00 00 e8 ec fd ff ff e9 35 ff ff ff 48 8b 43 30 49 63 ed <41> 0f b7 34 24 41 83 c5 01 48 8b 3c e8 66 89 b7 aa 02 00 00 81 e6\n[1026677.300877] RSP: 0018:ff3be62a6399bcc0 EFLAGS: 00010202\n[1026677.306556] RAX: ff28691e28980828 RBX: ff28691e41099828 RCX: 0000000000188000\n[1026677.314148] RDX: 0000000000000000 RSI: 0000000000000010 RDI: ff28691e41099828\n[1026677.321730] RBP: 0000000000000000 R08: 0000000000000000 R09: 0000000000000000\n[1026677.329311] R10: 0000000000000007 R11: ffffffffffffffc0 R12: 0000000000000010\n[1026677.336896] R13: 0000000000000000 R14: 0000000000000000 R15: ff28691e0eaa81a0\n[1026677.344472] FS: 0000000000000000(0000) GS:ff28693cbffc0000(0000) knlGS:0000000000000000\n[1026677.353000] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[1026677.359195] CR2: 0000000000000010 CR3: 0000000128df4001 CR4: 0000000000771ef0\n[1026677.366779] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n[1026677.374369] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n[1026677.381952] PKRU: 55555554\n[1026677.385116] Call Trace:\n[1026677.388023] <TASK>\n[1026677.390589] ?

Anteriormente, el controlador ice entraba en p\u00e1nico despu\u00e9s de la suspensi\u00f3n. Esto se debe a que el controlador *solo* llama a la funci\u00f3n ice_vsi_free_q_vectors() por s\u00ed mismo, cuando est\u00e1 suspendida. Desde la confirmaci\u00f3n b3e7b3a6ee92 (\"ice: evitar la eliminaci\u00f3n del puntero NULL durante la recarga\"), el controlador puso a cero num_q_vectors y solo lo restaur\u00f3 en ice_vsi_cfg_def(). Esto adem\u00e1s hace que la funci\u00f3n ice_rebuild() asigne un b\u00fafer de longitud cero, despu\u00e9s del cual se actualiza num_q_vectors, y luego el nuevo valor de num_q_vectors se usa para indexar en el b\u00fafer de longitud cero, lo que corrompe la memoria. La soluci\u00f3n implica asegurarse de que todo el c\u00f3digo que hace referencia a num_q_vectors solo lo haga despu\u00e9s de que se haya restablecido mediante ice_vsi_cfg_def(). No realic\u00e9 una bisecci\u00f3n completa, pero pude probar con el kernel 6.1.77 y ese controlador Ice funciona bien para suspender/reanudar sin p\u00e1nico, por lo que en alg\u00fan momento desde entonces, se introdujo este problema.

Since commit b3e7b3a6ee92 (\"ice: prevent\nNULL pointer deref during reload\") the driver has zeroed out\nnum_q_vectors, and only restored it in ice_vsi_cfg_def().\nThis further causes the ice_rebuild() function to allocate a zero length\nbuffer, after which num_q_vectors is updated, and then the new value of\nnum_q_vectors is used to index into the zero length buffer, which\ncorrupts memory.\nThe fix entails making sure all the code referencing num_q_vectors only\ndoes so after it has been reset via ice_vsi_cfg_def().\nI didn't perform a full bisect, but I was able to test against 6.1.77\nkernel and that ice driver works fine for suspend/resume with no panic,\nso sometime since then, this problem was introduced.\nAlso clean up an un-needed init of a local variable in the function\nbeing modified.\nPANIC from 6.8.0-rc1:\n[1026674.915596] PM: suspend exit\n[1026675.664697] ice 0000:17:00.1: PTP reset successful\n[1026675.664707] ice 0000:17:00.1: 2755 msecs passed between update to cached PHC time\n[1026675.667660] ice 0000:b1:00.0: PTP reset successful\n[1026675.675944] ice 0000:b1:00.0: 2832 msecs passed between update to cached PHC time\n[1026677.137733] ixgbe 0000:31:00.0 ens787: NIC Link is Up 1 Gbps, Flow Control: None\n[1026677.190201] BUG: kernel NULL pointer dereference, address: 0000000000000010\n[1026677.192753] ice 0000:17:00.0: PTP reset successful\n[1026677.192764] ice 0000:17:00.0: 4548 msecs passed between update to cached PHC time\n[1026677.197928] #PF: supervisor read access in kernel mode\n[1026677.197933] #PF: error_code(0x0000) - not-present page\n[1026677.197937] PGD 1557a7067 P4D 0\n[1026677.212133] ice 0000:b1:00.1: PTP reset successful\n[1026677.212143] ice 0000:b1:00.1: 4344 msecs passed between update to cached PHC time\n[1026677.212575]\n[1026677.243142] Oops: 0000 [#1] PREEMPT SMP NOPTI\n[1026677.247918] CPU: 23 PID: 42790 Comm: kworker/23:0 Kdump: loaded Tainted: G W 6.8.0-rc1+ #1\n[1026677.257989] Hardware name: Intel Corporation M50CYP2SBSTD/M50CYP2SBSTD, BIOS SE5C620.86B.01.01.0005.2202160810 02/16/2022\n[1026677.269367] Workqueue: ice ice_service_task [ice]\n[1026677.274592] RIP: 0010:ice_vsi_rebuild_set_coalesce+0x130/0x1e0 [ice]\n[1026677.281421] Code: 0f 84 3a ff ff ff 41 0f b7 74 ec 02 66 89 b0 22 02 00 00 81 e6 ff 1f 00 00 e8 ec fd ff ff e9 35 ff ff ff 48 8b 43 30 49 63 ed <41> 0f b7 34 24 41 83 c5 01 48 8b 3c e8 66 89 b7 aa 02 00 00 81 e6\n[1026677.300877] RSP: 0018:ff3be62a6399bcc0 EFLAGS: 00010202\n[1026677.306556] RAX: ff28691e28980828 RBX: ff28691e41099828 RCX: 0000000000188000\n[1026677.314148] RDX: 0000000000000000 RSI: 0000000000000010 RDI: ff28691e41099828\n[1026677.321730] RBP: 0000000000000000 R08: 0000000000000000 R09: 0000000000000000\n[1026677.329311] R10: 0000000000000007 R11: ffffffffffffffc0 R12: 0000000000000010\n[1026677.336896] R13: 0000000000000000 R14: 0000000000000000 R15: ff28691e0eaa81a0\n[1026677.344472] FS: 0000000000000000(0000) GS:ff28693cbffc0000(0000) knlGS:0000000000000000\n[1026677.353000] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[1026677.359195] CR2: 0000000000000010 CR3: 0000000128df4001 CR4: 0000000000771ef0\n[1026677.366779] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n[1026677.374369] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n[1026677.381952] PKRU: 55555554\n[1026677.385116] Call Trace:\n[1026677.388023] <TASK>\n[1026677.390589] ? __die+0x20/0x70\n[1026677.394105] ? page_fault_oops+0x82/0x160\n[1026677.398576] ? do_user_addr_fault+0x65/0x6a0\n[1026677.403307] ? exc_page_fault+0x6a/0x150\n[1026677.407694] ? asm_exc_page_fault+0x22/0x30\n[1026677.412349] ? ice_vsi_rebuild_set_coalesce+0x130/0x1e0 [ice]\n[1026677.4186\n---truncated---", "This is a flaw in the Linux kernel's ICE driver for Intel Ethernet controllers.
