Introduce an alternative mechanism for wifi drivers to communicate
the channel on which a frame was received.
ieee80211_inputm() was expecting that ic->ic_bss->ni_chan would correspond
to the channel which is currently being scanned. This dates back to older
devices which are manually tuned to the next channel by the driver during
SCAN->SCAN state transitions.
However, this approach is very awkward for drivers which scan across a
whole range of channels in firmware. Such drivers had an ugly workaround
in place which tweaked ni_chan for each received frame.
Introduce a channel number field in the Rx info struct which drivers
can use to indicate the channel on which a frame was received.
If this field is set, net80211 will use it instead of using the current
channel of ic_bss. Use this new mechanism in all affected drivers.
Tested by jmc@, sthen@, and myself on iwm(4) and iwx(4).

Implement additional error checking for aplsmc_read_key() such that we can
detect when we read a key that isn't supported by the firmware.
Only provide RTC functionality if the "CLKM" key is implemented.
Fixes reading the time on machines with old SMC firmware from macOS 11.x.

Always use letoh32(gh.gh_part_num) instead of NGPTPARTITIONS when
scanning the GPT partition table. gh.gh_part_num reflects the actual
size of the table read from/written to the disk and scanning
possible entries between this value and the maximum allowed size
of a partition table is pointless.
No intentional functional change.

Add a simple regress to verify that the infinite loop in BN_mod_sqrt()

Fix infinite loop in BN_mod_sqrt()
A bug in the implementation of the Tonelli-Shanks algorithm can lead to
an infinite loop. This loop can be hit in various ways, in particular on
decompressing an elliptic curve public key via EC_POINT_oct2point() - to
do this, one must solve y^2 = x^3 + ax + b for y, given x.
If a certificate uses explicit encoding for elliptic curve parameters,
this operation needs to be done during certificate verification, leading
to a DoS. In particular, everything dealing with untrusted certificates
is affected, notably TLS servers explicitly configured to request
client certificates (httpd, smtpd, various VPN implementations, ...).
Ordinary TLS servers do not consume untrusted certificates.
The problem is that we cannot assume that x^3 + ax + b is actually a
square on untrusted input and neither can we assume that the modulus
p is a prime. Ensuring that p is a prime is too expensive (it would
likely itself lead to a DoS). To avoid the infinite loop, fix the logic
to be more resilient and explicitly limit the number of iterations that
can be done. The bug is such that the infinite loop can also be hit for
primes = 3 (mod 4) but fortunately that case is optimized earlier.
It's also worth noting that there is a size bound on the field size
enforced via OPENSSL_ECC_MAX_FIELD_BITS (= 661), which help mitigate
further DoS vectors in presence of this fix.

Refactor prefix_adjout_update(). Move the new prefix logic up and
then just fall through the update path. This is more in line with
prefix_update() and will make further work simpler.

Add a test for expanding macros in large-community strings.
claudio [Tue, 15 Mar 2022 11:13:48 +0000 (11:13 +0000)]
Change how $macros are expanded in the config.
Expand $macros not only at the start of a yacc token but also inside STRING
elements. STRING elements are used e.g. for community specifications and
it makes sense to allow $FOO:$BAR to correctly expand. There is no expansion
of macros in quoted strings (both single and double quotes).
Factor out the macro expand logic and with this introduce its own lookup
buffer for the macro name. For expansion to work inside STRING the char
after the makro name must be a character not allowed in macro names (not
alpha-numerical or '_').
Add extra checks to set variables. Mainly restrict length of the name and
also make sure it does not include not allowed characters.

Fix Tx rate used by rtwn(4) and urtwn(4) for RTS frames.
Using ni_txrate for RTS is a bad choice since it could go up to 54 Mbit/s.
The AP needs to receive our RTS frame reliably. Usually, 1 Mbit/s is used
for RTS, but this hurts throughput and does not really make sense on today's
wifi networks.
Use 1 Mbit/s in 11b mode, and otherwise use 24 Mbit/s, as damien@
already hard-coded in urtwn long ago.
