Title
Bluetooth: HCI: Remove HCI_AMP support
Summary
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: HCI: Remove HCI_AMP support Since BT_HS has been remove HCI_AMP controllers no longer has any use so remove it along with the capability of creating AMP controllers. Since we no longer need to differentiate between AMP and Primary controllers, as only HCI_PRIMARY is left, this also remove hdev->dev_type altogether.

Bluetooth radio proximity is the adjacent-network vector.\nAC:L - Once an HCI_AMP controller is present \u2014 the default state on affected hardware, requiring no attacker setup \u2014 the inconsistent paths are reached deterministically by initiating an ACL/L2CAP connection and sending data; there is no race and no memory layout the attacker cannot influence.\nPR:N - An adjacent Bluetooth attacker needs no credentials on the target: `hci_conn_request_evt` and `l2cap_connect_cfm`/`l2cap_conn_add` run before any pairing or authorization, and `l2cap_connect` explicitly exempts the SDP PSM from the link-mode security check.\nUI:N - No victim action is required \u2014 inbound connection establishment and ACL data reception are handled autonomously by the kernel once Bluetooth is up.\nS:U - All corruption and crashes stay inside the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `hci_queue_acl()` builds ACL headers from `chan-\u003ehandle` rather than `conn-\u003ehandle` on AMP hdevs, so L2CAP payloads can be emitted tagged with the wrong link handle, and the state corruption in the connection/scheduler bookkeeping is of a class leverageable for kernel memory disclosure.\nI:H - `hci_num_comp_blocks_evt` applies an unbounded `conn-\u003esent -= block_count` to a `hci_chan` that should never have existed, underflowing an unsigned counter that drives `hci_quote_sent`/`hci_low_sent` quota arithmetic, and the ACL handle confusion lets frames be attributed to the wrong connection \u2014 kernel state under attacker influence.\nA:H - `__get_blocks()` divides by controller-supplied `hdev-\u003eblock_len` on the block-based path that only AMP controllers select, giving a divide-by-zero kernel oops; separately, `hci_sched_acl()` never drains the AMP queues so `chan-\u003edata_q` grows without bound until memory is exhausted."

Bluetooth radio proximity is the adjacent-network vector.\\nAC:L - Once an HCI_AMP controller is present \\u2014 the default state on affected hardware, requiring no attacker setup \\u2014 the inconsistent paths are reached deterministically by initiating an ACL/L2CAP connection and sending data; there is no race and no memory layout the attacker cannot influence.\\nPR:N - An adjacent Bluetooth attacker needs no credentials on the target: `hci_conn_request_evt` and `l2cap_connect_cfm`/`l2cap_conn_add` run before any pairing or authorization, and `l2cap_connect` explicitly exempts the SDP PSM from the link-mode security check.\\nUI:N - No victim action is required \\u2014 inbound connection establishment and ACL data reception are handled autonomously by the kernel once Bluetooth is up.\\nS:U - All corruption and crashes stay inside the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\\nC:H - `hci_queue_acl()` builds ACL headers from `chan-\u003ehandle` rather than `conn-\u003ehandle` on AMP hdevs, so L2CAP payloads can be emitted tagged with the wrong link handle, and the state corruption in the connection/scheduler bookkeeping is of a class leverageable for kernel memory disclosure.\\nI:H - `hci_num_comp_blocks_evt` applies an unbounded `conn-\u003esent -= block_count` to a `hci_chan` that should never have existed, underflowing an unsigned counter that drives `hci_quote_sent`/`hci_low_sent` quota arithmetic, and the ACL handle confusion lets frames be attributed to the wrong connection \\u2014 kernel state under attacker influence.\\nA:H - `__get_blocks()` divides by controller-supplied `hdev-\u003eblock_len` on the block-based path that only AMP controllers select, giving a divide-by-zero kernel
