Rework META_TARGETS so that it automatically adds META_DEPS to the targets.
This will only be done if the target is defined, so if the target is
defined after bsd.sys.mk is included then it needs to manually add
${META_DEPS} still.
Extract virtual port address from RQSTYPE_RPT_ID_ACQ.
This should close the race between request arriving on new target mode

Allow the handling of ICMP messages sent in response to SCTP packets
containing an INIT chunk. These need to be handled in case the peer
does not support SCTP and returns an ICMP messages indicating destination
unreachable, protocol unreachable.
When delivering an ICMP packet to the ctlinput function, ensure that
the outer IP header, the ICMP header, the inner IP header and the
first n bytes are stored in contgous memory. The ctlinput functions
currently rely on this for n = 8. This fixes a bug in case the inner IP
header had options.
While there, remove the options from the outer header and provide a
way to increase n to allow improved ICMP handling for SCTP. This will
be added in another commit.

Fix the types for the start, end, and count arguments to
arm_gic_fdt_alloc_resource. These were the old u_long where they should be
rman_res_t. Both of these are the same size on arm64 so this is just for
correctness, and would not have led to incorrect behaviour.

Ensure the received IP header gets 32-bits aligned.
The FreeBSD's TCP/IP stack assumes that the IP-header is 32-bits aligned
when decoding it. Else unaligned 32-bit memory access can happen, which
not all processor architectures support.
When downing a mlxen network adapter we need to check the port_up variable
to ensure we don't continue to transmit data or restart timers which can
reside in freed memory.
There are bunch of reports that this check fails at least on Nuvoton
NCT6776 chips. I don't see why this check needed there, and Linux does
not have it either. So far this check only made watchdogd unstopable.

Set the upper limit of the DMAP region to the limit of RAM as was found in
the physmap. This will reduce the likelihood of an issue where we have
device memory mapped in the DMAP. This can only happen if it is within the
same 1G block of normal memory.

Deprecate using hints.acpi.0.rsdp to communicate the RSDP to the
system. This uses the hints mechnanism. This mostly works today
because when there's no static hints (the default), this value can be
fetched from the hint. When there is a static hints file, the hint
passed from the boot loader to the kernel is ignored, but for the BIOS
case we're able to find it anyway. However, with UEFI, the fallback
doesn't work, so we get a panic instead.
Switch to acpi.rsdp and use TUNABLE_ULONG_FETCH instead. Continue to
generate the old values to allow for transitions. In addition, fall
back to the old method if the new method isn't present.
Simplify building libpam and fix libpam.a not containing the modules since r284345.
The change in r284345 moved the creation of openpam_static_modules.o to
lib/libpam/static_modules but never managed to get them into libpam.a.
Move this logic to lib/libpam/static_libpam and have it create a static
library for libpam.a The main lib/libpam/libpam will only create a
shared library. No redundancy in compilation or installation exists
in this solution.
This avoids requiring a pass with -D_NO_LIBPAM_SO_YET.
Separate POSIX mqueue objects in jails; actually, separate them by the
jail's root, so jails that don't have their own filesystem directory
also won't have their own mqueue namespace.
Separate POSIX sem/shm objects in jails, by prepending the jail's path
name to the object's "path". While the objects don't have real path
names, it's a filesystem-like namespace, which allows jails to be
kept to their own space, but still allows the system / jail parent to
access a jail's IPC.
Add sbuf variants ata_cmd_sbuf() and ata_res_sbuf(), and reimplement the

signature of ata_res_sbuf(). Its use in the tree seems to be very limited,
and the change makes it more consistent with the rest of the API.

Expose doreti as a global symbol on amd64 and i386.

Increase the arm64 kernel address space to 512GB, and the DMAP region to
2TB. The latter can be increased in 512GB chunks by adjusting the lower
address, however more work will be needed to increase the former.
There is still some work needed to only create a DMAP region for the RAM
address space as on ARM architectures all mappings should have the same
memory attributes, and these will be different for device and normal memory.

[urtwn] use/track the last good RSSI for a given node, rather than no RSSI.
Now that we're decap'ing A-MPDU frame, the firmware is only giving us
PHY status information for the whole PPDU, rather than duplicatig it
per frame.
So, we fake it by maintaining the RSSI that we saw in the node struct
and reuse it.
This prevents us from getting some pretty garbage looking default RSSI
values, which shows up as RSSI values of like "3" or "4" when doing
active traffic.

If the VOP_SETATTR() call that saves the exclusive create verifier failed,
the NFS server would leave the newly created vnode locked. This could
result in a file system that would not unmount and processes wedged,
waiting for the file to be unlocked.
Since this VOP_SETATTR() never fails for most file systems, this bug
doesn't normally manifest itself. I found it during testing of an
exported GlusterFS file system, which can fail.
This patch adds the vput() and changes the error to the correct NFS one.

Don't drop the g_topology_lock before freeing old_physpath. That
opens up a race where one thread can call vdev_geom_attrchanged,
set old_physpath, drop the g_topology_lock, then block trying to
acquire the SCL_STATE lock. Then another thread can come into
vdev_geom_attrchanged, set old_physpath to the same value, and
proceed to free it. When the first thread resumes, it will free
the same location.
It turns out that the SCL_STATE lock isn't needed. It was
originally added by gibbs to protect vd->vdev_physpath while
updating the same. However, the update process subsequently was
switched to an atomic operation (a pointer swap). Now, there is
no need for the SCL_STATE lock, and hence no need to drop the
g_topology_lock.
Make all CT Pass-Through (name server requests) asynchronous.
Previously we had to do it synchronously because we could not drop the lock
due to potential scratch memory use conflicts. Previous commits fixed that
collision, so here it goes -- slower and less reliable external requests
are executed asynchronously without spinning in tight loop and with more
safe timeout handling.
