* send: switch handshake stamp to an atomic
Rather than abusing the handshake lock, we're much better off just using
a boring atomic64 for this. It's simpler and performs better. Also, while
we're at it, we set the handshake stamp both before and after the
calculations, in case the calculations block for a really long time waiting
for the RNG to initialize.
* compat: better atomic acquire/release backport
This should fix compilation and correctness on several platforms.
* crypto: move simd context to specific type
This was a suggestion from Andy Lutomirski on LKML.
* chacha20poly1305: selftest: use arrays for test vectors
We no longer have lines so long that they're rejected by SMTP servers.
* qemu: add easy git harness
This makes it a bit easier to use our qemu harness for testing our mainline
integration tree.
* curve25519-x86_64: avoid use of r12
This causes problems with RAP and KERNEXEC for PaX, as r12 is a
reserved register.
* chacha20: use memmove in case buffers overlap
A small correctness fix that we never actually hit in WireGuard but is
important especially for moving this into a general purpose library.
* curve25519-hacl64: simplify u64_eq_mask
* curve25519-hacl64: correct u64_gte_mask
Two bitmath fixes from Samuel, which come complete with a z3 script proving
their correctness.
* timers: include header in right file
This fixes compilation in some environments.
* netlink: don't start over iteration on multipart non-first allowedips
Matt Layher found a bug where a netlink dump of peers would never terminate in
some circumstances, causing wg(8) to keep trying forever. We now have a fix as
well as a unit test to mitigate this, and we'll be looking to create a fuzzer
out of Matt's nice library.

Unauthenticated EAPOL-Key decryption in wpa_supplicant
Published: August 8, 2018
Identifiers:
- CVE-2018-14526
Latest version available from: https://w1.fi/security/2018-1/
Vulnerability
A vulnerability was found in how wpa_supplicant processes EAPOL-Key
frames. It is possible for an attacker to modify the frame in a way that
makes wpa_supplicant decrypt the Key Data field without requiring a
valid MIC value in the frame, i.e., without the frame being
authenticated. This has a potential issue in the case where WPA2/RSN
style of EAPOL-Key construction is used with TKIP negotiated as the
pairwise cipher. It should be noted that WPA2 is not supposed to be used
with TKIP as the pairwise cipher. Instead, CCMP is expected to be used
and with that pairwise cipher, this vulnerability is not applicable in
practice.
When TKIP is negotiated as the pairwise cipher, the EAPOL-Key Key Data
field is encrypted using RC4. This vulnerability allows unauthenticated
EAPOL-Key frames to be processed and due to the RC4 design, this makes
it possible for an attacker to modify the plaintext version of the Key
Data field with bitwise XOR operations without knowing the contents.
This can be used to cause a denial of service attack by modifying
GTK/IGTK on the station (without the attacker learning any of the keys)
which would prevent the station from accepting received group-addressed
frames. Furthermore, this might be abused by making wpa_supplicant act
as a decryption oracle to try to recover some of the Key Data payload
(GTK/IGTK) to get knowledge of the group encryption keys.
Full recovery of the group encryption keys requires multiple attempts
(128 connection attempts per octet) and each attempt results in
disconnection due to a failure to complete the 4-way handshake. These
failures can result in the AP/network getting disabled temporarily or
even permanently (requiring user action to re-enable) which may make it
impractical to perform the attack to recover the keys before the AP has
already changes the group keys. By default, wpa_supplicant is enforcing
at minimum a ten second wait time between each failed connection
attempt, i.e., over 20 minutes waiting to recover each octet while
hostapd AP implementation uses 10 minute default for GTK rekeying when
using TKIP. With such timing behavior, practical attack would need large
number of impacted stations to be trying to connect to the same AP to be
able to recover sufficient information from the GTK to be able to
determine the key before it gets changed.
Vulnerable versions/configurations
All wpa_supplicant versions.

Thanks to Mathy Vanhoef of the imec-DistriNet research group of KU
Leuven for discovering and reporting this issue.
Possible mitigation steps
- Remove TKIP as an allowed pairwise cipher in RSN/WPA2 networks. This
can be done also on the AP side.
- Merge the following commits to wpa_supplicant and rebuild:
WPA: Ignore unauthenticated encrypted EAPOL-Key data
This patch is available from https://w1.fi/security/2018-1/
- Update to wpa_supplicant v2.7 or newer, once available

Spell out the "up" keyword (which has users), add it to usage output,

This commit adds support for the OCEDO Koala
SOC: Qualcomm QCA9558 (Scorpion)
RAM: 128MB
FLASH: 16MiB
WLAN1: QCA9558 2.4 GHz 802.11bgn 3x3
WLAN2: QCA9880 5 GHz 802.11nac 3x3
INPUT: RESET button
LED: Power, LAN, WiFi 2.4, WiFi 5, SYS
Serial: Header Next to Black metal shield
Pinout is 3.3V - GND - TX - RX (Arrow Pad is 3.3V)
The Serial setting is 115200-8-N-1.
Tested and working:
- Ethernet
- 2.4 GHz WiFi
- 5 GHz WiFi
- TFTP boot from ramdisk image
- Installation via ramdisk image
- OpenWRT sysupgrade
- Buttons
- LEDs
Installation seems to be possible only through booting an OpenWRT
ramdisk image.
Hold down the reset button while powering on the device. It will load a
ramdisk image named 'koala-uImage-initramfs-lzma.bin' from 192.168.100.8.
Note: depending on the present software, the device might also try to
pull a file called 'koala-uimage-factory'. Only the name differs, it
is still used as a ramdisk image.
Wait for the ramdisk image to boot. OpenWRT can be written to the flash
via sysupgrade or mtd.
Due to the flip-flop bootloader which we not (yet) support, you need to
set the partition the bootloader is selecting. It is possible from the
initramfs image with
> fw_setenv bootcmd run bootcmd_1
Afterwards you can reboot the device.

Jonas Gorski commented on the previous patch:
|This is actually the wrong fix and papers over an issue in one of our
|local patches.
|
|We intentionally allow regmap to be built as a module, see
|
|/target/linux/generic/hack-4.14/259-regmap_dynamic.patch
|[...]
|[The regulator code] optionally supports regmap thanks to the stubs
|provided if regmap is disabled - which breaks if you compile regmap
|as a module.
In order to mitigate this issue, this patch reverts the previous patch
and replaces the existing IS_ENABLED(CONFIG_REGMAP) with
IS_REACHABLE(CONFIG_REGMAP). This solves this particular issue as the
regulator code will now automatically fallback to the regmap stubs in
case the kmod-regmap module is enabled, but nothing else sets
CONFIG_REGMAP=y.
Note: There's still a potential issue that this patch doesn't solve:
If someone ever wants to make a OpenWrt kernel package for a
regulator module that requires the REGMAP feature for a target that
doesn't set CONFIG_REGMAP=y but has CONFIG_REGULATOR=y, the resulting
kmod-regulator-xyz package will not work on the target.
Luckily, there aren't any in-tree OpenWrt kernel module packages for
regulators at the moment. On the bright side: regmap is a critical
part nowadays and all new and upcoming architectures require it by
default. This will likely only ever be a problem for legacy targets
and devices that cannot afford to enable REGMAP.

o configure default compile to include isochronous support (use configure --disable-isochronous to remove support)
o replace 2.0.11's --vary-load option with a more general -b option to include <mean>,<stdev>, e.g. -b 100m,40m, which will pull from a log normal distribution every 0.1 seconds
