Amd64 uses relocatable object files as the modules format. It is good
WRT not having unneeded overhead for PIC code, in particular, due to
absence of useless GOT and PLT. But the cost is that the module
linking process cannot use hash to speed up the symbol lookup, and
that each reference to the symbol requiring a relocation, instead of
single-place relocation in GOT.
Cache the successfull symbol lookup results in the module symbol
table, using the newly allocated SHN_FBSD_CACHED value from
SHN_LOOS-HIOS range as an indicator. The SHN_FBSD_CACHED together
with the non-existent definition of the found symbol are reverted
after successfull relocations, which is done under kld_sx lock, so it
should not be visible to other consumers of the symbol table.

This was not (and still is not) connected to the build, but the EFI
loader is in the process of being built for other than amd64 so these
files ought to live in their eventual MD location.
The use of CHAN_TCP_WINDOW_DEFAULT here was fixed in upstream OpenSSH

Use the correct packet maximum sizes for remote port and agent forwarding.
Prevents the server from killing the connection if too much data is queued
and an excessively large packet gets sent. bz #1360, ok djm@.
The change was lost due to the the way the original upstream HPN patch
modified this code. It was re-adding the original OpenSSH code and never
was properly fixed to use the new value.

header and not only partial flags and fields. Firewalls can attach
classification tags to the outgoing mbufs which should be copied to
all the new fragments. Else only the first fragment will be let
through by the firewall. This can easily be tested by sending a large
ping packet through a firewall. It was also discovered that VLAN
related flags and fields should be copied for packets traversing
through VLANs. This is all handled by "m_dup_pkthdr()".
Regarding the MAC policy check in ip_fragment(), the tag provided by
the originating mbuf is copied instead of using the default one
provided by m_gethdr().

There are cases when gpioled nodes in DTS come from different sources
(e.g. standard Beaglebone Black LEDs in main DTS + shield LEDs in
overlay DTS) so instead of handling only first compatible node go

where we want to create a new IP datagram.
o Add support for RFC6864, which allows to set IP ID for atomic IP
datagrams to any value, to improve performance. The behaviour is
controlled by net.inet.ip.rfc6864 sysctl knob, which is enabled by
default.
o In case if we generate IP ID, use counter(9) to improve performance.
o Gather all code related to IP ID into ip_id.c.

A couple of internal functions used by malloc(9) and uma truncated
a size_t down to an int. This could cause any number of issues
(e.g. indefinite sleeps, memory corruption) if any kernel
subsystem tried to allocate 2GB or more through malloc. zfs would
attempt such an allocation when run on a system with 2TB or more
of RAM.
Note to self: When this is MFCed, sparc64 needs the same fix.

On Ethernet packets have a minimal length, so very short packets get padding
appended to them. This padding is not stripped off in ip6_input() (due to
support for IPv6 Jumbograms, RFC2675).
That means PF needs to be careful when reassembling fragmented packets to not
include the padding in the reassembled packet.
While here also remove the 'Magic from ip_input.' bits. Splitting up and
re-joining an mbuf chain here doesn't make any sense.

When forwarding fragmented IPv6 packets and filtering with PF we
reassemble and refragment. That means we generate new fragment headers
and a new fragment ID.
We already save the fragment IDs so we can do the reassembly so it's
straightforward to apply the incoming fragment ID on the refragmented
packets.

on reads or writes, the time marks are used to display idle time by
w(1) [1]. Instead, use vfs.devfs.dotimes as the selector of default
precision vs. using time_second. The later gives seconds precision,
which is good enough for the purpose.
Note that timestamp updates are unlocked and the updates itself, as
well as the check in devfs_timestamp, are non-atomic.

the top-level HAL.
The athstats program is blindly using a copy of the ar5212 ANI stats structure
to pull out ANI statistics/state and this is problematic for the AR9300
HAL.
So:
* Define HAL_ANI_STATS and HAL_ANI_STATE
* Use HAL_ANI_STATS inside the AR5212 HAL
This commit doesn't (yet) convert the ar5212AniState -> HAL_ANI_STATE when
exporting it to userland; that'll come in the next commit.
Summary:
Add "GELI Passphrase:" prompt to boot loader.
A new loader.conf(5) option of geom_eli_passphrase_prompt="YES" will now
allow you to enter your geli(8) root-mount credentials prior to invoking
the kernel.
See check-password.4th(8) for details.

Test Plan:
Drop a head copy of check-password.4th into /boot and then apply the patch
(only the patch to /boot/check-password.4th is required; no other changes are
required but you do have to have a HEAD copy of check-password.4th to
apply the patch).
NB: The rest of your /boot files can be up to 2 years old but no older.
NB: The test won't work unless your kernel has the following change
https://svnweb.freebsd.org/base?view=revision&revision=273489
Now, put into /boot/loader.conf:
geom_eli_passphrase_prompt="YES"
and reboot.
You should be prompted for a GELI passphrase before the menu (if enabled),
just after loading loader.conf(5).
NB: It doesn't matter if you're using GELI or not. However if you are using
GELI and a sufficiently new enough release (has SVN r273489) and you entered
the proper passphrase to mount your GELI encrypted root device(s), you should
notice that the boot process did not stop (you went from loader all the way to login).
