Most kernel memory that is allocated after boot does not need to be
executable. There are a few exceptions. For example, kernel modules
do need executable memory, but they don't use UMA or malloc(9). The
BPF JIT compiler also needs executable memory and did use malloc(9)
until r317072.
(Note that a side effect of r316767 was that the "small allocation"
path in UMA on amd64 already returned non-executable memory. This
meant that some calls to malloc(9) or the UMA zone(9) allocator could
return executable memory, while others could return non-executable
memory. This change makes the behavior consistent.)
This change makes malloc(9) return non-executable memory unless the new
M_EXEC flag is specified. After this change, the UMA zone(9) allocator
will always return non-executable memory, and a KASSERT will catch
attempts to use the M_EXEC flag to allocate executable memory using
uma_zalloc() or its variants.
Allocations that do need executable memory have various choices. They
may use the M_EXEC flag to malloc(9), or they may use a different VM
interfact to obtain executable pages.
Now that malloc(9) again allows executable allocations, this change also
reverts most of r317072.

Lack of functioning link and activity LEDs on devices without an EEPROM
is expected (not a bug). Quoting the EVB-LAN7850 User's Guide:
When configured with the default internal register settings, the
Ethernet Link status LEDs are not enabled. To enable Ethernet Link
status LEDs, enable the EEPROM.
This is an artifact of the different ways in which the evaluation board
can be used. End-user USB-Ethernet adapters using the Microchip LAN78XX
or LAN7515 controllers should use an EEPROM or have OTP configuration,
if their product configuration does not match the boot default register
configuration.
Sponsored by: The FreeBSD Foundation
Differences between LAN7800 and LAN7850 from the driver's perspective:
* The LAN7800 muxes EEPROM signals with LEDs, so LED mode needs to be
disabled when reading/writing EEPROM. The EEPROM is not muxed on the
LAN7850.
* The Linux driver enables automatic duplex and speed detection when
there is no EEPROM, for the LAN7800 only. With this FreeBSD driver
LAN7850-based adapters without a configuration EEPROM fail to link
(with or without the automatic duplex and speed detection code), so
I have just followed the example of the Linux driver for now.

the first exp-run with lld as the system linker.
As of r327783 we enabled LLD_BOOTSTRAP by default on amd64, using lld as
the linker to link the kernel and world, but GNU ld was still installed
as /usr/bin/ld.
The vast majority of issues observed when building ports with lld as the
system linker have now been solved, so set LLD_IS_LD by default on amd64

The original Berkeley Software Distributions were made in the 1980's

force in most of the countries in the Americas. It required an
affirmative statement of rights reservation, typically using 'All

notices to invoke this treaty to ensure maximal copyright protection.
In the 1990's, Latin America coutries ratifeid the Berne Convention on
copyrights which prohibited them from requiring an affirmative
statement to reserve the rights. When Nicaragua ratified in 2000, the
Buenos Ares Convention of 1910 was effectively repealed. This made all
the 'All Rights Reserved' phrases obsolete and legal deadweight most
of the time, and certainly in the cases removed here.
Since it's no longer required, and is in fact meaningless, core has

ones you can get with an OTG-capable board - as consoles. It boils down
to adding the device name to kern.console sysctl, although doing that
requires jumping through some hoops. It doesn't change the actual
operation of those virtual devices. The point is to make it possible
for init(8) to recognize them as console devices and to launch getty(8)
for them, when configured as "onifconsole" in ttys(5). The point of
that, in turn, is to add such entries to the default ttys(5), so that

The ocs_fc(4) driver supports the following hardware:
Emulex 16/8G FC GEN 5 HBAS
LPe15004 FC Host Bus Adapters
LPe160XX FC Host Bus Adapters
Emulex 32/16G FC GEN 6 HBAS
LPe3100X FC Host Bus Adapters
LPe3200X FC Host Bus Adapters
The driver supports target and initiator mode, and also supports FC-Tape.
Note that the driver only currently works on little endian platforms. It
is only included in the module build for amd64 and i386, and in GENERIC
on amd64 only.

Add a new "interleave" allocation policy which stripes pages across
domains with a stride or width keeping contiguity within a multi-page
region.
Move the kernel to the dedicated numbered cpuset #2 making it possible
to assign kernel threads and memory policy separately from user. This
also eliminates the need for the complicated interrupt binding code.
Add a sysctl API for viewing and manipulating domainsets. Refactor some
of the cpuset_t manipulation code using the generic bitset type so that
it can be used for both. This probably belongs in a dedicated subr file.
Attempt to improve the include situation.

For some reason, the other link - https://lists.FreeBSD.org/ - needs
the trailing slash, otherwise man(8) renders it in a weird way. No
idea why's that. At least try to be consistent. Revert it when the
other link gets fixed.

In a virtual machine, VMCI is exposed as a regular PCI device. The primary
communication mechanisms supported are a point-to-point bidirectional
transport based on a pair of memory-mapped queues, and asynchronous
notifications in the form of datagrams and doorbells. These features are
available to kernel level components such as vSockets through the VMCI
kernel API. In addition to this, the VMCI kernel API provides support for
receiving events related to the state of the VMCI communication channels,
and the virtual machine itself.

DTB Overlays are useful to change/add nodes to a dtb without the need to
modify it.
Add support for building dtbo during buildkernel.
The goal of DTBO present in the FreeBSD source tree is to fill a gap in
time when we submit changes upstream (Linux). Instead of waiting 2 to 4 months
we can add a DTBO in tree in the meantime.
This is not for adding DTBO for capes/hat/addon boards, those will be
better to put in a ports.
This is also not for enabling a i2c/spi/pwm controller on certain pins,
each user have a different use case for those (which pins to use etc ...)
and we cannot have all possible configuration.
Add a dtbo for sun8i-h3-sid which add the SID node missing in upstream dts.

Forwarded packets passed through PFIL_OUT, which made it difficult for
firewalls to figure out if they were forwarding or producing packets. This in
turn is an issue for pf for IPv6 fragment handling: it needs to call
ip6_output() or ip6_forward() to handle the fragments. Figuring out which was
difficult (and until now, incorrect).
Having pfil distinguish the two removes an ugly piece of code from pf.
Introduce a new variant of the netpfil callbacks with a flags variable, which
has PFIL_FWD set for forwarded packets. This allows pf to reliably work out if
a packet is forwarded.

This is originally based on a patch from David Chisnall for soft-float
N64 but has since been updated to support O32, N32, and hard-float ABIs.
The soft-float O32, N32, and N64 support has been committed upstream.
The hard-float changes are still in review upstream.
Enable LLVM_LIBUNWIND on mips when building with a suitable (C+11-capable)
toolchain. This has been tested with external GCC for all ABIs and
O32 and N64 with clang.

ECN (ABE)" proposal to the New Reno congestion control algorithm module.
ABE reduces the amount of congestion window reduction in response to
ECN-signalled congestion relative to the loss-inferred congestion response.
More details about ABE can be found in the Internet-Draft:
https://tools.ietf.org/html/draft-ietf-tcpm-alternativebackoff-ecn
The implementation introduces four new sysctls:
- net.inet.tcp.cc.abe defaults to 0 (disabled) and can be set to non-zero to
enable ABE for ECN-enabled TCP connections.
- net.inet.tcp.cc.newreno.beta and net.inet.tcp.cc.newreno.beta_ecn set the
multiplicative window decrease factor, specified as a percentage, applied to
the congestion window in response to a loss-based or ECN-based congestion
signal respectively. They default to the values specified in the draft i.e.
beta=50 and beta_ecn=80.
- net.inet.tcp.cc.abe_frlossreduce defaults to 0 (disabled) and can be set to
non-zero to enable the use of standard beta (50% by default) when repairing
loss during an ECN-signalled congestion recovery episode. It enables a more
conservative congestion response and is provided for the purposes of
experimentation as a result of some discussion at IETF 100 in Singapore.
The values of beta and beta_ecn can also be set per-connection by way of the
TCP_CCALGOOPT TCP-level socket option and the new CC_NEWRENO_BETA or
CC_NEWRENO_BETA_ECN CC algo sub-options.
