However, the\nsocket stays alive, and it still points to the TLS context, which is now\ndeallocated. If a netdev goes up, while the connection is still active,\nand the data flow resumes after a number of TCP retransmissions, it will\nlead to a use-after-free of the TLS context.\r\n\r\nThis commit addresses this bug by keeping the context alive until its\nnormal destruction, and implements the necessary fallbacks, so that the\nconnection can resume in software (non-offloaded) kTLS mode.\r\n\r\nOn the TX side tls_sw_fallback is used to encrypt all packets. The RX\nside already has all the necessary fallbacks, because receiving\nnon-decrypted packets is supported. The thing needed on the RX side is\nto block resync requests, which are normally produced after receiving\nnon-decrypted packets.\r\n\r\nThe necessary synchronization is implemented for a graceful teardown:\nfirst the fallbacks are deployed, then the driver resources are released\n(it used to be possible to have a tls_dev_resync after tls_dev_del).\r\n\r\nA new flag called TLS_RX_DEV_DEGRADED is added to indicate the fallback\nmode. It\u0026apos;s used to skip the RX resync logic completely, as it becomes\nuseless, and some objects may be released (for example, resync_async,\nwhich is allocated and freed by the driver).(CVE-2021-47131)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm/amdgpu: Fix a use-after-free\r\n\r\nlooks like we forget to set ttm-\u0026gt;sg to NULL.\nHit panic below\r\n\r\n[ 1235.844104] general protection fault, probably for non-canonical address 0x6b6b6b6b6b6b7b4b: 0000 [#1] SMP DEBUG_PAGEALLOC NOPTI\n[ 1235.989074] Call Trace:\n[ 1235.991751]  sg_free_table+0x17/0x20\n[ 1235.995667]  amdgpu_ttm_backend_unbind.cold+0x4d/0xf7 [amdgpu]\n[ 1236.002288]  amdgpu_ttm_backend_destroy+0x29/0x130 [amdgpu]\n[ 1236.008464]  ttm_tt_destroy+0x1e/0x30 [ttm]\n[ 1236.013066]  ttm_bo_cleanup_memtype_use+0x51/0xa0 [ttm]\n[ 1236.018783]  ttm_bo_release+0x262/0xa50 [ttm]\n[ 1236.023547]  ttm_bo_put+0x82/0xd0 [ttm]\n[ 1236.027766]  amdgpu_bo_unref+0x26/0x50 [amdgpu]\n[ 1236.032809]  amdgpu_amdkfd_gpuvm_alloc_memory_of_gpu+0x7aa/0xd90 [amdgpu]\n[ 1236.040400]  kfd_ioctl_alloc_memory_of_gpu+0xe2/0x330 [amdgpu]\n[ 1236.046912]  kfd_ioctl+0x463/0x690 [amdgpu](CVE-2021-47142)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nnet/smc: remove device from smcd_dev_list after failed device_add()\r\n\r\nIf the device_add() for a smcd_dev fails, there\u0026apos;s no cleanup step that\nrolls back the earlier list_add().

However, the\nsocket stays alive, and it still points to the TLS context, which is now\ndeallocated. If a netdev goes up, while the connection is still active,\nand the data flow resumes after a number of TCP retransmissions, it will\nlead to a use-after-free of the TLS context.\r\n\r\nThis commit addresses this bug by keeping the context alive until its\nnormal destruction, and implements the necessary fallbacks, so that the\nconnection can resume in software (non-offloaded) kTLS mode.\r\n\r\nOn the TX side tls_sw_fallback is used to encrypt all packets. The RX\nside already has all the necessary fallbacks, because receiving\nnon-decrypted packets is supported. The thing needed on the RX side is\nto block resync requests, which are normally produced after receiving\nnon-decrypted packets.\r\n\r\nThe necessary synchronization is implemented for a graceful teardown:\nfirst the fallbacks are deployed, then the driver resources are released\n(it used to be possible to have a tls_dev_resync after tls_dev_del).\r\n\r\nA new flag called TLS_RX_DEV_DEGRADED is added to indicate the fallback\nmode. It\u0026apos;s used to skip the RX resync logic completely, as it becomes\nuseless, and some objects may be released (for example, resync_async,\nwhich is allocated and freed by the driver).(CVE-2021-47131)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm/amdgpu: Fix a use-after-free\r\n\r\nlooks like we forget to set ttm-\u0026gt;sg to NULL.\nHit panic below\r\n\r\n[ 1235.844104] general protection fault, probably for non-canonical address 0x6b6b6b6b6b6b7b4b: 0000 [#1] SMP DEBUG_PAGEALLOC NOPTI\n[ 1235.989074] Call Trace:\n[ 1235.991751]  sg_free_table+0x17/0x20\n[ 1235.995667]  amdgpu_ttm_backend_unbind.cold+0x4d/0xf7 [amdgpu]\n[ 1236.002288]  amdgpu_ttm_backend_destroy+0x29/0x130 [amdgpu]\n[ 1236.008464]  ttm_tt_destroy+0x1e/0x30 [ttm]\n[ 1236.013066]  ttm_bo_cleanup_memtype_use+0x51/0xa0 [ttm]\n[ 1236.018783]  ttm_bo_release+0x262/0xa50 [ttm]\n[ 1236.023547]  ttm_bo_put+0x82/0xd0 [ttm]\n[ 1236.027766]  amdgpu_bo_unref+0x26/0x50 [amdgpu]\n[ 1236.032809]  amdgpu_amdkfd_gpuvm_alloc_memory_of_gpu+0x7aa/0xd90 [amdgpu]\n[ 1236.040400]  kfd_ioctl_alloc_memory_of_gpu+0xe2/0x330 [amdgpu]\n[ 1236.046912]  kfd_ioctl+0x463/0x690 [amdgpu](CVE-2021-47142)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nnet/smc: remove device from smcd_dev_list after failed device_add()\r\n\r\nIf the device_add() for a smcd_dev fails, there\u0026apos;s no cleanup step that\nrolls back the earlier list_add().
