Hardware timestamp reporting is disabled by default as it produces many
extra events which are not handled by consumers like libinput.
Add hw.usb.wmt.timestamps=1 tunable to loader.conf to enable it.

In Hybrid mode, the number of contacts that can be reported in one
report is less than the maximum number of contacts that the device
supports. For example, a device that supports a maximum of 4
concurrent physical contacts, can set up its top-level collection to
deliver a maximum of two contacts in one report. If four contact
points are present, the device can break these up into two serial
reports that deliver two contacts each.

When using NFS-over-TLS, an NFS client can optionally provide an X.509
certificate to the server during the TLS handshake. For some situations,
such as different NFS servers or different certificates being mapped
to different user credentials on the NFS server, there may be a need
for different mounts to provide different certificates.
This new mount option called "tlscertname" may be used to specify a
non-default certificate be provided. This alernate certificate will
be stored in /etc/rpc.tlsclntd in a file with a name based on what is
provided by this mount option.
Original if_dwc driver used m_defrag as an implementation shortcut but on
1000Mb networks it affects performance. Implement multi-descriptor support for
TX path.
Tested on RK3399-Firefly, patch adds ~15% of network throughput.

The existing values correspond to x86 exception vector numbers, but the
trap numbers used in the kernel do not match these 1-to-1. Prefer the
definitions from x86/trap.h, as they are what actually get passed to
kdb_trap(). This is of little consequence, as gdb_cpu_signal() only
reports the trap reason (signal number) to the gdb client.
This is limited to the subset of trap values for which kdb_trap() is
reachable.

Fix broken CTLFLAG_SKIP when present on the first child of the requested
node.
We don't need to ignore skip for the first node because in sysctl_all()
we've implicitly visited the first node already when oid is specified.
The first call to show_var() in here is after we have iterated to the
next node. When the command line specifically requests a non-node sysctl
we go straight into show_var() without calling sysctl_all().

When copying sockaddrs out to userspace, we pad them to a multiple of
the platform alignment (sizeof(long)). However, some sockaddr sizes,
such as struct sockaddr_dl, are not an integer multiple of the
alignment, so we may end up copying out uninitialized bytes.
Fix this by always bouncing through a pre-zeroed sockaddr_storage.

g_handleattr_int() consumes the bio if the attribute matches, so when we
check bp->bio_cmd bp may have been freed.
Move GETATTR handling to a separate function to avoid the problem. We
do not need to set bio_completed for such bios, g_handleattr_int() will
handle it. Also remove the setting of bio_resid before the
devstat_end_transaction_bio() call. All of the md(4) bio handlers set
bio_resid already.

We use a bitmap to track which cylinder groups have changed between
snapshot creation and filesystem suspension. The "legs" of the bitmap
are four bytes wide (see ACTIVESET()) so we must round up the allocation
size to a multiple of four bytes.
I believe this bug is harmless since UMA/kmem_* will both pad the
allocation and zero the full allocation. Note that malloc() does inline
zeroing when the allocation size is known at compile-time.

Vectored aio will require each aiocb to be associated with multiple
bios, so we can't store a link to the latter from the former. But we
don't really need to. aio_biowakeup already knows the bio it's using,
and the other fields can be stored within the bio and/or buf itself.
Also, remove the unused kaiocb.backend2 field.

The adr instruction allows for an address of +-1M from the instruction.
If we replace these with an adrp and an add instruction we can generate
an address +-4G. The adrp will get an address of the 4k page the label
is within, and the add uses the :lo12: prefix to add just the low bits
to this address.
This will allow us to move things around with fewer issues than if we
needed to keep them within the +-1MB range.

When tearing down a VNET, netgraph sends shutdown messages to all of the
nodes before detaching interfaces (SI_SUB_NETGRAPH comes before
SI_SUB_INIT_IF in teardown order). ng_ether nodes handle this by
destroying themselves without detaching from the parent ifnet. Then,
when ifnets go away they detach their ng_ether nodes again, triggering a
use-after-free.
Handle this by modifying ng_ether_shutdown() to detach from the ifnet.
If the shutdown was triggered by an ifnet being destroyed, we will clear
priv->ifp in the ng_ether detach callback, so priv->ifp may be NULL.
Also get rid of the printf in vnet_netgraph_uninit(). It can be
triggered trivially by ng_ether since ng_ether_shutdown() persists the
node unless NG_REALLY_DIE is set.
