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.

Dumping debug registers on GP1 MSIx and error conditions, such as TX

during errors. The register dump includes:
- Boot stage
- IPC control
- IPC status
- Mailbox registers

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:

This reverts commit b16b327edb4d030fb4c8fe38c7d299074d47ee3f.
The sysfs node introduced by this patch could potentially race with user
space. The original motivation - Support configuring altsetting from the
user space will be added by another series.

This reverts commit 75ddcd5ad40ecd9fbc9f5a7a2ed0e1e74921db3c.
This patch doesn't work quite well - It's observed that with this 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.

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 "Supported Altsettings" and "Switch Altsetting" commands
that allow the user space program to configure the altsetting freely.
This patch is tested on ChromeOS devices. The USB Bluetooth models
(CVSD, TRANS alt3, and TRANS alt6) could pass the stress HFP test narrow
band speech and wide band speech.

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 implements host wakeup feature by reading the device tree property
wakeup-source and 'wakeup' interrupt, and nxp,wakeout-pin, and configuring
it as a FALLING EDGE triggered interrupt.
When host is suspended, a trigger from the WAKE_OUT pin of the
controller wakes it up.
To enable this feature, both device tree properties are needed to be
defined.

These two commits preallocated two per-cpu variables in
ip6_route_info_create() as fib_nh_common_init() and fib6_nh_init()
were expected to be called under RCU.
* commit d27b9c40dbd6 ("ipv6: Preallocate nhc_pcpu_rth_output in
ip6_route_info_create().")
* commit 5720a328c3e9 ("ipv6: Preallocate rt->fib6_nh->rt6i_pcpu in
ip6_route_info_create().")
Now these functions can be called without RCU and can use GFP_KERNEL.
Let's revert the commits.

Since commit c4837b9853e5 ("ipv6: Split ip6_route_info_create()."),
ip6_route_info_create_nh() uses GFP_ATOMIC as it was expected to be
called under RCU.
Now, we can call it without RCU and use GFP_KERNEL.
Let's pass gfp_flags to ip6_route_info_create_nh().

Commit 71c0efb6d12f ("ipv6: Factorise ip6_route_multipath_add().") split
a loop in ip6_route_multipath_add() so that we can put rcu_read_lock()
between ip6_route_info_create() and ip6_route_info_create_nh().
We no longer need to do so as ip6_route_info_create_nh() does not require
RCU now.

Commit 169fd62799e8 ("ipv6: Get rid of RTNL for SIOCADDRT and
RTM_NEWROUTE.") added rcu_read_lock() covering
ip6_route_info_create_nh() and __ip6_ins_rt() to guarantee that
nexthop and netdev will not go away.
However, as reported by syzkaller [0], ip_tun_build_state() calls
dst_cache_init() with GFP_KERNEL during the RCU critical section.
ip6_route_info_create_nh() fetches nexthop or netdev depending on
whether RTA_NH_ID is set, and struct fib6_info holds a refcount
of either of them by nexthop_get() or netdev_get_by_index().
netdev_get_by_index() looks up a dev and calls dev_hold() under RCU.
So, we need RCU only around nexthop_find_by_id() and nexthop_get()
( and a few more nexthop code).
Let's add rcu_read_lock() there and remove rcu_read_lock() in
ip6_route_add() and ip6_route_multipath_add().
Now these functions called from fib6_add() need RCU:
- inet6_rt_notify()
- fib6_drop_pcpu_from() (via fib6_purge_rt())
- rt6_flush_exceptions() (via fib6_purge_rt())
- ip6_ignore_linkdown() (via rt6_multipath_rebalance())
All callers of inet6_rt_notify() need RCU, so rcu_read_lock() is
added there.

Commit f130a0cc1b4f ("inet: fix lwtunnel_valid_encap_type() lock

I'm converting nexthop and IPv6 routing table to per-netns RTNL or RCU.

Let's remove the argument.

Once allocated, the IPv6 routing table is not freed until
netns is dismantled.
fib6_get_table() uses rcu_read_lock() while iterating
net->ipv6.fib_table_hash[], but it's not needed and
rather confusing.
Because some callers have this pattern,
table = fib6_get_table();
rcu_read_lock();
/* ... use table here ... */
rcu_read_unlock();
[ See: addrconf_get_prefix_route(), ip6_route_del(),
rt6_get_route_info(), rt6_get_dflt_router() ]
and this looks illegal but is actually safe.
Let's remove rcu_read_lock() in fib6_get_table() and pass true
to the last argument of hlist_for_each_entry_rcu() to bypass
the RCU check.
Note that protection is not needed but RCU helper is used to
avoid data-race.

AFAIU always returning -1 from lockdep's compare function
basically disables checking of dependencies between given

Right now we only nest them under protection of rtnl_lock.
Mostly in unregister_netdevice_many() and dev_close_many().

Cover three recent cases:
1. missing ops locking for the lowers during netdev_sync_lower_features
2. missing locking for dev_set_promiscuity (plus netdev_ops_assert_locked
with a comment on why/when it's needed)
3. rcu lock during team_change_rx_flags
Verified that each one triggers when the respective fix is reverted.
Not sure about the placement, but since it all relies on teaming,
added to the teaming directory.
One ugly bit is that I add NETIF_F_LRO to netdevsim; there is no way
to trigger netdev_sync_lower_features without it.

When the other peer calls shutdown(SHUT_RD), there is a chance that
the send() call could occur before the message carrying the close
information arrives over the transport. In such cases, the send()
might still succeed. To avoid this race, let's retry the send() call
a few times, ensuring the test is more reliable.
Sleep a little before trying again to avoid flooding the other peer
and filling its receive buffer, causing false-negative.
