SSLv3 has been deprecated since 2015 (and broken since 2014: "POODLE"); it
should not have shipped in FreeBSD 11 (2016) or 12 (2018). No one should use
it, and if they must, they can use some implementation outside of base.
There are three symbols removed with OPENSSL_NO_SSL3_METHOD:
SSLv3_client_method
SSLv3_method
SSLv3_server_method
These symbols exist to request an explicit SSLv3 connection to a server.
There is no good reason for an application to link or invoke these symbols
instead of TLS_method(), et al (née SSLv23_method, et al). Applications
that do so have broken cryptography.
Define these symbols for some pedantic definition of ABI stability, but
remove the functionality again (r361392) after r362620.

The later firmware devices (including iwn!) support multiple configuration
contexts for a lot of things, leaving it up to the firmware to decide
which channel and vap is active. This allows for things like off-channel
p2p sta/ap operation and other weird things.
However, net80211 is still focused on a "net80211 drives all" when it comes to driving
the NIC, and as part of this history a lot of these options are global and not per-VAP.
This is fine when net80211 drives things and all VAPs share a single channel - these
parameters importantly really reflect the state of the channel! - but it will increasingly
be not fine when we start supporting more weird configurations and more recent NICs.
Yeah, recent like iwn/iwm.
Anyway - so, migrate all of the HT protection, legacy protection and preamble
stuff to be per-VAP. The global flags are still there; they're now calculated
in a deferred taskqueue that mirrors the old behaviour. Firmware based drivers
which have per-VAP configuration of these parameters can now just listen to the
per-VAP options.
What do I mean by per-channel? Well, the above configuration parameters really
are about interoperation with other devices on the same channel. Eg, HT protection
mode will flip to legacy/mixed if it hears ANY BSS that supports non-HT stations or
indicates it has non-HT stations associated. So, these flags really should be
per-channel rather than per-VAP, and then for things like "do i need short preamble
or long preamble?" turn into a "do I need it for this current operating channel".
Then any VAP using it can query the channel that it's on, reflecting the real
required state.
This patch does none of the above paragraph just yet.
I'm also cheating a bit - I'm currently not using separate taskqueues for
the beacon updates and the per-VAP configuration updates. I can always further
split it later if I need to but I didn't think it was SUPER important here.
So:
* Create vap taskqueue entries for ERP/protection, HT protection and short/long
preamble;
* Migrate the HT station count, short/long slot station count, etc - into per-VAP
variables rather than global;
* Fix a bug with my WME work from a while ago which made it per-VAP - do the WME
beacon update /after/ the WME update taskqueue runs, not before;
* Any time the HT protmode configuration changes or the ERP protection mode
config changes - schedule the task, which will call the driver without the
net80211 lock held and all correctly serialised;
* Use the global flags for beacon IEs and VAP flags for probe responses and
other IE situations.
The primary consumer of this is ath10k. iwn could use it when sending RXON,
but we don't support IBSS or AP modes on it yet, and I'm not yet sure whether
it's required in STA mode (ie whether the firmware parses beacons to change
protection mode or whether we need to.)
Tested:
* AR9280, STA/AP
* AR9380, DWDS STA+STA/AP
* ath10k work, STA/AP
* Intel 6235, STA
* Various rtwn / run NICs, DWDS STA and STA configurations
The global counters were not SMP-friendly. Use per-CPU counters
instead.

We can just use libsa version, just as loader.efi does. The only concern is,
libsa zalloc is using fixed size heap region, I did pick 64MB as other

When the RISC-V port was initially committed to FreeBSD, GCC would
generate 64-bit long doubles, and the definitions in _fpmath.h reflected
that. This was changed to 128-bit in GCC later that year [1], but the
definitions were never updated, despite the documented workaround. This
causes printf(3) and friends to interpret only the low 64-bits of a long
double in ldtoa, thereby printing incorrect values.
Update the definitions now that both clang and GCC generate 128-bit long
doubles.

This effectively mirrors our libc implementation, but with minor fudging --
name needs to be copied in from userspace, so we just copy it straight into
stack-allocated memfd_name into the correct position rather than allocating
memory that needs to be cleaned up.
The sealing-related fcntl(2) commands, F_GET_SEALS and F_ADD_SEALS, have
also been implemented now that we support them.
Note that this implementation is still not quite at feature parity w.r.t.
the actual Linux version; some caveats, from my foggy memory:
- Need to implement SHM_GROW_ON_WRITE, default for memfd (in progress)
- LTP wants the memfd name exposed to fdescfs
- Linux allows open() of an fdescfs fd with O_TRUNC to truncate after dup.
(?)
Interested parties can install and run LTP from ports (devel/linux-ltp) to
confirm any fixes.
