Title
wifi: iwlwifi: mvm: pick the version of SESSION_PROTECTION_NOTIF
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: pick the version of SESSION_PROTECTION_NOTIF When we want to know whether we should look for the mac_id or the link_id in struct iwl_mvm_session_prot_notif, we should look at the version of SESSION_PROTECTION_NOTIF. This causes WARNINGs: WARNING: CPU: 0 PID: 11403 at drivers/net/wireless/intel/iwlwifi/mvm/time-event.c:959 iwl_mvm_rx_session_protect_notif+0x333/0x340 [iwlmvm] RIP: 0010:iwl_mvm_rx_session_protect_notif+0x333/0x340 [iwlmvm] Code: 00 49 c7 84 24 48 07 00 00 00 00 00 00 41 c6 84 24 78 07 00 00 ff 4c 89 f7 e8 e9 71 54 d9 e9 7d fd ff ff 0f 0b e9 23 fe ff ff <0f> 0b e9 1c fe ff ff 66 0f 1f 44 00 00 90 90 90 90 90 90 90 90 90 RSP: 0018:ffffb4bb00003d40 EFLAGS: 00010202 RAX: 0000000000000000 RBX: ffff9ae63a361000 RCX: ffff9ae4a98b60d4 RDX: ffff9ae4588499c0 RSI: 0000000000000305 RDI: ffff9ae4a98b6358 RBP: ffffb4bb00003d68 R08: 0000000000000003 R09: 0000000000000010 R10: ffffb4bb00003d00 R11: 000000000000000f R12: ffff9ae441399050 R13: ffff9ae4761329e8 R14: 0000000000000001 R15: 0000000000000000 FS: 0000000000000000(0000) GS:ffff9ae7af400000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000055fb75680018 CR3: 00000003dae32006 CR4: 0000000000f70ef0 PKRU: 55555554 Call Trace: <IRQ> ? show_regs+0x69/0x80 ? __warn+0x8d/0x150 ? iwl_mvm_rx_session_protect_notif+0x333/0x340 [iwlmvm] ? report_bug+0x196/0x1c0 ? handle_bug+0x45/0x80 ? exc_invalid_op+0x1c/0xb0 ? asm_exc_invalid_op+0x1f/0x30 ? iwl_mvm_rx_session_protect_notif+0x333/0x340 [iwlmvm] iwl_mvm_rx_common+0x115/0x340 [iwlmvm] iwl_mvm_rx_mq+0xa6/0x100 [iwlmvm] iwl_pcie_rx_handle+0x263/0xa10 [iwlwifi] iwl_pcie_napi_poll_msix+0x32/0xd0 [iwlwifi]
