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.

This lets one interrupt DDB's output, which is useful if paging is
disabled and the output device is slow.
This follows a previous implementation in svn r311952 / git
5fddef7999 which was reverted because it
broke DDB type-ahead.
Now, try this again, but with a 512-byte type-ahead buffer. While there
is buffer space, control input is handled and non-control input is
buffered. When the buffer is exhausted, the default is to print a
warning and drop further non-control input in order to continue handling
control input. sysctl debug.ddb.prioritize_control_input can be set to
0 to instead preserve all input but lose immediate handling of control
input. This could for example effect pasting of a large script into the
ddb console.

(Note I am also applying this to main and stable/13, to restore the old
libcxxrt ABI and to avoid having to maintain a compat library.)
After the recent cherry-picking of libcxxrt commits 0ee0dbfb0d and
d2b3fadf2d, users reported that editors/libreoffice packages from the
official package builders did not start anymore. It turns out that the
combination of these commits subtly changes the ABI, requiring all
applications that depend on internal details of struct _Unwind_Exception
(available via unwind-arm.h and unwind-itanium.h) to be recompiled.
However, the FreeBSD package builders always use -RELEASE jails, so
these still use the old declaration of struct _Unwind_Exception, which
is not entirely compatible. In particular, LibreOffice uses this struct
in its internal "uno bridge" component, where it attempts to setup its
own exception handling mechanism.
To fix this incompatibility, go back to the old declarations of struct
_Unwind_Exception, and restore the __LP64__ specific workaround we had
in place before (which was to cope with yet another, older ABI bug).
Effectively, this reverts upstream libcxxrt commits 88bdf6b290da
("Specify double-word alignment for ARM unwind") and b96169641f79
("Updated Itanium unwind"), and reapplies our commit 3c4fd2463b
("libcxxrt: add padding in __cxa_allocate_* to fix alignment").

TSFOOR happens if a beacon with a given TSF isn't received within the
programmed/expected TSF value, plus/minus a fudge range. (OOR == out of range.)
If this happens then it could be because the baseband/mac is stuck, or
the baseband is deaf. So, do a cold reset and resync the beacon to
try and unstick the hardware.
It also happens when a bad AP decides to err, slew its TSF because they
themselves are resetting and they don't preserve the TSF "well."
This has fixed a bunch of weird corner cases on my 2GHz AP radio upstairs
here where it occasionally goes deaf due to how much 2GHz noise is up
here (and ANI gets a little sideways) and this unsticks the station
VAP.
For AP modes a hung baseband/mac usually ends up as a stuck beacon
and those have been addressed for a long time by just resetting the
hardware. But similar hangs in station mode didn't have a similar
recovery mechanism.
Tested:
* AR9380, STA mode, 2GHz/5GHz
* AR9580, STA mode, 5GHz
* QCA9344 SoC w/ on-board wifi (TL-WDR4300/3600 devices); 2GHz
STA mode
Right now ts_antenna is either 0 or 1 in each supported HAL so
this is purely a sanity check.
Later on if I ever get magical free time I may add some extensions
for the NICs that can have slightly more complicated antenna switches
for transmit and I'd like this to not bust memory.
Implement a driver for the RTC embedded in the RK805/RK808 power
management system used for RK3328 and RK3399 SoCs.
Based on experiments on my RK808, setting the time doesn't alter the

in calling clock_schedule().

We have seen several cases of processes which have become "stuck" in
kern_sigsuspend(). When this occurs, the kernel's td_sigblock_val
is set to 0x10 (one block outstanding) and the userspace copy of the
word is set to 0 (unblocked). Because the kernel's cached value
shows that signals are blocked, kern_sigsuspend() blocks almost all
signals, which means the process hangs indefinitely in sigsuspend().
It is not entirely clear what is causing this condition to occur.
However, it seems to make sense to add some protection against this
case by fetching the latest sigfastblock value from userspace for
syscalls which will sleep waiting for signals. Here, the change is
applied to kern_sigsuspend() and kern_sigtimedwait().

Before the pcb is copied to the new thread during cpu_fork() and
cpu_copy_thread(), the kernel re-reads the current register values in
case they are stale. This is done by setting PCB_FULL_IRET in
pcb_flags.
This works fine for user threads, but the creation of kernel processes
and kernel threads do not follow the normal synchronization rules for
pcb_flags. Specifically, new kernel processes are always forked from
thread0, not from curthread, so adjusting pcb_flags via a simple
instruction without the LOCK prefix can race with thread0 running on
another CPU. Similarly, kthread_add() clones from the first thread in
the relevant kernel process, not from curthread. In practice, Netflix
encountered a panic where the pcb_flags in the first kthread of the
KTLS process were trashed due to update_pcb_bases() in
cpu_copy_thread() running from thread0 to create one of the other KTLS
threads racing with the first KTLS kthread calling fpu_kern_thread()
on another CPU. In the panicking case, the write to update pcb_flags
in fpu_kern_thread() was lost triggering an "Unregistered use of FPU
in kernel" panic when the first KTLS kthread later tried to use the
FPU.

The existing code masked off all bits that it didn't know about. To be
future-proof, we should save and restore the entire fpcr/fpsr registers.
Additionally, the existing fesetenv() was incorrectly setting the rounding
mode in fpsr instead of fpcr.
This patch stores fpcr in the high 32 bits of fenv_t and fpsr in the low
bits instead of trying to interleave them in a single 32-bit field.
Technically, this is an ABI break if you re-compile parts of your code or
pass a fenv_t between DSOs that were compiled with different versions
of fenv.h. However, I believe we should fix this since the existing code
was broken and passing fenv_t across DSOs should rarely happen.
