After length decisions, we've decided that the if_wg(4) driver and
related work is not yet ready to live in the tree. This driver has
larger security implications than many, and thus will be held to
more scrutiny than other drivers.
Please also see the related message sent to the freebsd-hackers@
and freebsd-arch@ lists by Kyle Evans <kevans@FreeBSD.org> on
2021/03/16, with the subject line "Removing WireGuard Support From Base"
for additional context.
This is the culmination of about a week of work from three developers to
fix a number of functional and security issues. This patch consists of
work done by the following folks:
- Jason A. Donenfeld <Jason@zx2c4.com>
- Matt Dunwoodie <ncon@noconroy.net>
- Kyle Evans <kevans@FreeBSD.org>
Notable changes include:
- Packets are now correctly staged for processing once the handshake has
completed, resulting in less packet loss in the interim.
- Various race conditions have been resolved, particularly w.r.t. socket
and packet lifetime (panics)
- Various tests have been added to assure correct functionality and
tooling conformance
- Many security issues have been addressed
- if_wg now maintains jail-friendly semantics: sockets are created in
the interface's home vnet so that it can act as the sole network
connection for a jail
- if_wg no longer fails to remove peer allowed-ips of 0.0.0.0/0
- if_wg now exports via ioctl a format that is future proof and
complete. It is additionally supported by the upstream
wireguard-tools (which we plan to merge in to base soon)
- if_wg now conforms to the WireGuard protocol and is more closely
aligned with security auditing guidelines
Note that the driver has been rebased away from using iflib. iflib
poses a number of challenges for a cloned device trying to operate in a
vnet that are non-trivial to solve and adds complexity to the
implementation for little gain.
The crypto implementation that was previously added to the tree was a
super complex integration of what previously appeared in an old out of
tree Linux module, which has been reduced to crypto.c containing simple
boring reference implementations. This is part of a near-to-mid term
goal to work with FreeBSD kernel crypto folks and take advantage of or
improve accelerated crypto already offered elsewhere.
There's additional test suite effort underway out-of-tree taking
advantage of the aforementioned jail-friendly semantics to test a number
of real-world topologies, based on netns.sh.
Also note that this is still a work in progress; work going further will
be much smaller in nature.

In the CheriBSD CI we reproducibly see the first test in sys/audit
(administrative:acct_failure) fail due to a missing startup message.
It appears this is caused by a race condition when starting auditd:
`service auditd onestart` returns as soon as the initial auditd() parent
exits (after the daemon(3) call).
We can avoid this problem by setting up the auditd infrastructure
in-process: libauditd contains audit_quick_{start,stop}() functions that
look like they are ideally suited to this task.
This patch also avoids forking lots of shell processes for each of the 418
tests by using `auditon(A_SENDTRIGGER, &trigger, sizeof(trigger))` to check
for a running auditd(8) instead of using `service auditd onestatus`.
With these two changes (and D28388 to fix the XFAIL'd test) I can now
boot and run `cd /usr/tests/sys/audit && kyua test` without any failures
in a single-core QEMU instance. Before there would always be at least one
failed test.
Besides making the tests more reliable in CI, a nice side-effect of this
change is that it also significantly speeds up running them by avoiding
lots of fork()/execve() caused by shell scripts:
Running kyua test on an AArch64 QEMU took 315s before and now takes 68s,
so it's roughly 3.5 times faster. This effect is even larger when running
on a CHERI-RISC-V QEMU since emulating CHERI instructions on an x86 host
is noticeably slower than emulating AArch64.

Traditionally routing socket code did almost zero checks on
the input message except for the most basic size checks.
This resulted in the unclear KPI boundary for the routing system code
(`rtrequest*` and now `rib_action()`) w.r.t message validness.
Multiple potential problems and nuances exists:
* Host bits in RTAX_DST sockaddr. Existing applications do send prefixes
with hostbits uncleared. Even `route(8)` does this, as they hope the kernel
would do the job of fixing it. Code inside `rib_action()` needs to handle
it on its own (see `rt_maskedcopy()` ugly hack).
* There are multiple way of adding the host route: it can be DST without
netmask or DST with /32(/128) netmask. Also, RTF_HOST has to be set correspondingly.
Currently, these 2 options create 2 DIFFERENT routes in the kernel.
* no sockaddr length/content checking for the "secondary" fields exists: nothing
stops rtsock application to send sockaddr_in with length of 25 (instead of 16).
Kernel will accept it, install to RIB as is and propagate to all rtsock consumers,
potentially triggering bugs in their code. Same goes for sin_port, sin_zero, etc.
The goal of this change is to make rtsock verify all sockaddr and prefix consistency.
Said differently, `rib_action()` or internals should NOT require to change any of the
sockaddrs supplied by `rt_addrinfo` structure due to incorrectness.
To be more specific, this change implements the following:
* sockaddr cleanup/validation check is added immediately after getting sockaddrs from rtm.
* Per-family dst/netmask checks clears host bits in dst and zeros all dst/netmask "secondary" fields.
* The same netmask checking code converts /32(/128) netmasks to "host" route case
(NULL netmask, RTF_HOST), removing the dualism.
* Instead of allowing ANY "known" sockaddr families (0<..<AF_MAX), allow only actually
supported ones (inet, inet6, link).
* Automatically convert `sockaddr_sdl` (AF_LINK) gateways to
`sockaddr_sdl_short`.

rtinit[1]() is a function used to add or remove interface address prefix routes,
similar to ifa_maintain_loopback_route().
It was intended to be family-agnostic. There is a problem with this approach
in reality.
1) IPv6 code does not use it for the ifa routes. There is a separate layer,
nd6_prelist_(), providing interface for maintaining interface routes. Its part,
responsible for the actual route table interaction, mimics rtenty() code.
2) rtinit tries to combine multiple actions in the same function: constructing
proper route attributes and handling iterations over multiple fibs, for the
non-zero net.add_addr_allfibs use case. It notably increases the code complexity.
3) dstaddr handling. flags parameter re-uses RTF_ flags. As there is no special flag
for p2p connections, host routes and p2p routes are handled in the same way.
Additionally, mapping IFA flags to RTF flags makes the interface pretty messy.
It make rtinit() to clash with ifa_mainain_loopback_route() for IPV4 interface
aliases.
4) rtinit() is the last customer passing non-masked prefixes to rib_action(),
complicating rib_action() implementation.
5) rtinit() coupled ifa announce/withdrawal notifications, producing "false positive"
ifa messages in certain corner cases.
To address all these points, the following has been done:
* rtinit() has been split into multiple functions:
- Route attribute construction were moved to the per-address-family functions,
dealing with (2), (3) and (4).
- funnction providing net.add_addr_allfibs handling and route rtsock notificaions
is the new routing table inteface.
- rtsock ifa notificaion has been moved out as well. resulting set of funcion are only
responsible for the actual route notifications.
Side effects:
* /32 alias does not result in interface routes (/32 route and "host" route)
* RTF_PINNED is now set for IPv6 prefixes corresponding to the interface addresses

However, when accessing a file via mmap, there is no possible way to bypass
the cache completely. This change fixes a deadlock that would happen when
an mmap'd write tried to invalidate a portion of the cache, wrongly assuming
that a write couldn't possibly come from cache if direct_io were set.
Arguably, we could instead disable mmap for files with FOPEN_DIRECT_IO set.
But allowing it is less likely to cause user complaints, and is more in

device tree blobs. As these are targeting current generation ISAs.

Main part is that kern_copyin on amd64 after LA57 should query the top
of UVA for correct operations. In fact it should started doing that
after the workaround for AMD bug with IRET in the last user page was
fixed by reducing UVA by a page.
Also since we started calculating top of UVA, fix MIPS according to
the comment.

Messing with gnop devices under a zpool fails in this test, causing
the pool to be suspended and eventually the system to deadlock.
Skip the test for now until the issue is resolved.

The primary benefit is maintaining a completely shared
code base with the community allowing FreeBSD to receive
new features sooner and with less effort.
I would advise against doing 'zpool upgrade'
or creating indispensable pools using new
features until this change has had a month+
to soak.
Work on merging FreeBSD support in to what was
at the time "ZFS on Linux" began in August 2018.
I first publicly proposed transitioning FreeBSD
to (new) OpenZFS on December 18th, 2018. FreeBSD
support in OpenZFS was finally completed in December
2019. A CFT for downstreaming OpenZFS support in
to FreeBSD was first issued on July 8th. All issues
that were reported have been addressed or, for
a couple of less critical matters there are
pull requests in progress with OpenZFS. iXsystems
has tested and dogfooded extensively internally.
The TrueNAS 12 release is based on OpenZFS with
some additional features that have not yet made
it upstream.
Improvements include:
project quotas, encrypted datasets,
allocation classes, vectorized raidz,
vectorized checksums, various command line
improvements, zstd compression.
Thanks to those who have helped along the way:
Ryan Moeller, Allan Jude, Zack Welch, and many
others.

RTF_HOST indicates whether route is a host route
(netmask is empty or /{32,128}).
Check that if netmask is empty and host route is not specified, kernel
returns an error.

Thanks to r364064, the name cache now returns a hit where previously it
would miss. Adjust the expectations accordingly.

In C (not C++), 'naked' inline is almost always a mistake. Either use
static inline (this is appropriate for most cases), or extern inline.

This avoids injecting errors into the test system's mirrors.
gnop seems like a good solution here but it injects errors at the wrong
place vs where these tests expect and does not support a 'max global count'
like the failpoints do with 'n*' syntax.
