Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth and wireless.
Current release - regressions:
- af_unix: allow passing cred for embryo without SO_PASSCRED/SO_PASSPIDFD

disappears under traffic
- ipv6: move fib6_config_validate() to ip6_route_add(), prevent
invalid routes

prevent kernel crashes
- wifi: ath11k: avoid burning CPU in ath11k_debugfs_fw_stats_request()
for 3 sec if fw_stats_done is not set"

BT_SK_PA_SYNC is only valid for Broadcast Sinks which means socket used
for Broadcast Sources wouldn't be able to use the likes of getpeername
to read out the sockaddr_iso_bc fields which may have been update (e.g.
bc_sid).

When using and existing adv_info instance for broadcast source it
needs to be updated to periodic first before it can be reused, also in
case the existing instance already have data hci_set_adv_instance_data
cannot be used directly since it would overwrite the existing data so
this reappend the original data after the Broadcast ID, if one was
generated.
Example:
bluetoothctl># Add PBP to EA so it can be later referenced as the BIS ID
bluetoothctl> advertise.service 0x1856 0x00 0x00
bluetoothctl> advertise on

Depending on the security set the response to L2CAP_LE_CONN_REQ shall be
just L2CAP_CR_LE_ENCRYPTION if only encryption when BT_SECURITY_MEDIUM

In 'mgmt_hci_cmd_sync()', check whether the size of parameters passed
in 'struct mgmt_cp_hci_cmd_sync' matches the total size of the data
(i.e. 'sizeof(struct mgmt_cp_hci_cmd_sync)' plus trailing bytes).
Otherwise, large invalid 'params_len' will cause 'hci_cmd_sync_alloc()'
to do 'skb_put_data()' from an area beyond the one actually passed to
'mgmt_hci_cmd_sync()'.

Use separate link type id for unicast and broadcast ISO connections.
These connection types are handled with separate HCI commands, socket
API is different, and hci_conn has union fields that are different in
the two cases, so they shall not be mixed up.
Currently in most places it is attempted to distinguish ucast by
bacmp(&c->dst, BDADDR_ANY) but it is wrong as dst is set for bcast sink
hci_conn in iso_conn_ready(). Additionally checking sync_handle might be
OK, but depends on details of bcast conn configuration flow.

Bluetooth needs some way for user to get supported so_timestamping flags
for the different socket types.
Use SIOCETHTOOL API for this purpose. As hci_dev is not associated with
struct net_device, the existing implementation can't be reused, so we
add a small one here.
Add support (only) for ETHTOOL_GET_TS_INFO command. The API differs
slightly from netdev in that the result depends also on socket type.

Up until now it has been assumed that the application would be able to
enter the advertising SID in sockaddr_iso_bc.bc_sid, but userspace has
no access to SID since the likes of MGMT_EV_DEVICE_FOUND cannot carry
it, so it was left unset (0x00) which means it would be unable to
synchronize if the broadcast source is using a different SID e.g. 0x04:

Although commit 75ddcd5ad40e ("Bluetooth: btusb: Configure altsetting
for HCI_USER_CHANNEL") has enabled the HCI_USER_CHANNEL user to send out
SCO data through USB Bluetooth chips, it's observed that with the patch
HFP is flaky on most of the existing USB Bluetooth controllers: Intel
chips sometimes send out no packet for Transparent codec; MTK chips may
generate SCO data with a wrong handle for CVSD codec; RTK could split
the data with a wrong packet size for Transparent codec; ... etc.
To address the issue above one needs to reset the altsetting back to
zero when there is no active SCO connection, which is the same as the
BlueZ behavior, and another benefit is the bus doesn't need to reserve
bandwidth when no SCO connection.
This patch adds the infrastructure that allow the user space program to
talk to Bluetooth drivers directly:
- Define the new packet type HCI_DRV_PKT which is specifically used for
communication between the user space program and the Bluetooth drviers
- hci_send_frame intercepts the packets and invokes drivers' HCI Drv
callbacks (so far only defined for btusb)
- 2 kinds of events to user space: Command Status and Command Complete,
the former simply returns the status while the later may contain
additional response data.

This fixes the regression introduced by 50c1241e6a8a ("Bluetooth: l2cap:
Check encryption key size on incoming connection") introduced a check for
l2cap_check_enc_key_size which checks for hcon->enc_key_size which may
not be initialized if HCI_OP_READ_ENC_KEY_SIZE is still pending.
If the key encryption size is known, due previously reading it using
HCI_OP_READ_ENC_KEY_SIZE, then store it as part of link_key/smp_ltk
structures so the next time the encryption is changed their values are
used as conn->enc_key_size thus avoiding the racing against
HCI_OP_READ_ENC_KEY_SIZE.
Now that the enc_size is stored as part of key the information the code
then attempts to check that there is no downgrade of security if
HCI_OP_READ_ENC_KEY_SIZE returns a value smaller than what has been
previously stored.

This is required for passing PTS test cases:
- L2CAP/COS/CED/BI-14-C
Multiple Signaling Command in one PDU, Data Truncated, BR/EDR,
Connection Request
- L2CAP/COS/CED/BI-15-C
Multiple Signaling Command in one PDU, Data Truncated, BR/EDR,
Disconnection Request
The test procedure defined in L2CAP.TS.p39 for both tests is:
1. The Lower Tester sends a C-frame to the IUT with PDU Length set
to 8 and Channel ID set to the correct signaling channel for the
logical link. The Information payload contains one L2CAP_ECHO_REQ
packet with Data Length set to 0 with 0 octets of echo data and
one command packet and Data Length set as specified in Table 4.6
and the correct command data.
2. The IUT sends an L2CAP_ECHO_RSP PDU to the Lower Tester.
3. Perform alternative 3A, 3B, 3C, or 3D depending on the IUT’s
response.
Alternative 3A (IUT terminates the link):
3A.1 The IUT terminates the link.
3A.2 The test ends with a Pass verdict.
Alternative 3B (IUT discards the frame):
3B.1 The IUT does not send a reply to the Lower Tester.
Alternative 3C (IUT rejects PDU):
3C.1 The IUT sends an L2CAP_COMMAND_REJECT_RSP PDU to the
Lower Tester.
Alternative 3D (Any other IUT response):
3D.1 The Upper Tester issues a warning and the test ends.
4. The Lower Tester sends a C-frame to the IUT with PDU Length set
to 4 and Channel ID set to the correct signaling channel for the
logical link. The Information payload contains Data Length set to
0 with an L2CAP_ECHO_REQ packet with 0 octets of echo data.
5. The IUT sends an L2CAP_ECHO_RSP PDU to the Lower Tester.
With expected outcome:
In Steps 2 and 5, the IUT responds with an L2CAP_ECHO_RSP.
In Step 3A.1, the IUT terminates the link.
In Step 3B.1, the IUT does not send a reply to the Lower Tester.
In Step 3C.1, the IUT rejects the PDU.
In Step 3D.1, the IUT sends any valid response.

Documentation/networking/timestamping.rst implies TX timestamping OPT_ID
tskey increments for each sendmsg. In practice: TCP socket increments
it for all sendmsg, timestamping on or off, but UDP only when
timestamping is on. The user-visible counter resets when OPT_ID is
turned on, so difference can be seen only if timestamping is enabled for
some packets only (eg. via SO_TIMESTAMPING CMSG).
Fix BT sockets to work in the same way: stream sockets increment tskey
for all sendmsg (seqpacket already increment for timestamped only).

Support enabling TX timestamping for some skbs, and track them until
packet completion. Generate software SCM_TSTAMP_COMPLETION when getting
completion report from hardware.
Generate software SCM_TSTAMP_SND before sending to driver. Sending from
driver requires changes in the driver API, and drivers mostly are going
to send the skb immediately.
Make the default situation with no COMPLETION TX timestamping more
efficient by only counting packets in the queue when there is nothing to
track. When there is something to track, we need to make clones, since
the driver may modify sent skbs.
The tx_q queue length is bounded by the hdev flow control, which will
not send new packets before it has got completion reports for old ones.

Commit b35108a51cf7 ("jiffies: Define secs_to_jiffies()") introduced
secs_to_jiffies(). As the value here is a multiple of 1000, use
secs_to_jiffies() instead of msecs_to_jiffies() for readability.
