dnsmasq v2.80test8 adds the ability to ignore dhcp client's requests for
specific hostnames. Clients claiming certain hostnames and thus
claiming DNS namespace represent a potential security risk. e.g. a
malicious host could claim 'wpad' for itself and redirect other web
client requests to it for nefarious purpose. See CERT VU#598349 for more
details.
Some Samsung TVs are claiming the hostname 'localhost', it is believed
not (yet) for nefarious purposes.
/usr/share/dnsmasq/dhcpbogushostname.conf contains a list of hostnames
in correct syntax to be excluded. e.g.
dhcp-name-match=set:dhcp_bogus_hostname,localhost
Inclusion of this file is controlled by uci option dhcpbogushostname
which is enabled by default.
To be absolutely clear, DHCP leases to these requesting hosts are still
permitted, but they do NOT get to claim ownership of the hostname
itself and hence put into DNS for other hosts to be confused/manipulate by.

Support for -D got broken in the 2.0.11 release by the upstream commit
218d8c667944 ("first pass L2 mode w/UDP checks, v4 only"). After that
commit clients were still able to connect but no traffic was passed.
It was reported and is fixed now in the upstream git repository.
Backport two patches to fix this. The first one is just a requirement
for the later to apply. The second one is the real fix and it needed
only a small adjustment to apply without backporing the commit
10887b59c7e7 ("fix --txstart-time report messages").

* Prefer if (IS_ENABLED(...)) over ifdef mazes when possible.
* Call simd_relax() within any preempt-disabling glue code every once in a

* Prefer compiler-defined architecture macros in assembly code, which puts us

* Non-static symbols are prefixed with wg_ to avoid polluting the global

* Return a bool from simd_relax() indicating whether or not we were
rescheduled.
* Reflect the proper simd conditions on arm.
* Do not reorder lines in Kbuild files for the simd asm-generic addition,
since we don't want to cause merge conflicts.
* WARN() if the selftests fail in Zinc, since if this is an initcall, it won't
block module loading, so we want to be loud.
* Document some interdependencies beside include statements.
* Add missing static statement to fpu init functions.
* Use union in chacha to access state words as a flat matrix, instead of
casting a struct to a u8 and hoping all goes well. Then, by passing around
that array as a struct for as long as possible, we can update counter[0]
instead of state[12] in the generic blocks, which makes it clearer what's
happening.
* Remove __aligned(32) for chacha20_ctx since we no longer use vmovdqa on x86,
and the other implementations do not require that kind of alignment either.
* Submit patch to ARM tree for adjusting RiscPC's cflags to be -march=armv3 so
that we can build code that uses umull.
* Allow CONFIG_ARM[64] to imply [!]CONFIG_64BIT, and use zinc arch config
variables consistently throughout.
* Document rationale for the 2^26->2^64/32 conversion in code comments.
* Convert all of remaining BUG_ON to WARN_ON.
* Replace `bxeq lr` with `reteq lr` in ARM assembler to be compatible with old
ISAs via the macro in <asm/assembler.h>.
* Do not allow WireGuard to be a built-in if IPv6 is a module.
* Writeback the base register and reorder multiplications in the NEON x25519
implementation.
* Try all combinations of different implementations in selftests, so that
potential bugs are more immediately unearthed.
* Self tests and SIMD glue code work with #include, which lets the compiler
optimize these. Previously these files were .h, because they were included,
but a simple grep of the kernel tree shows 259 other files that carry out
this same pattern. Only they prefer to instead name the files with a .c
instead of a .h, so we now follow the convention.
* Support many more platforms in QEMU, especially big endian ones.
* Kernels < 3.17 don't have read_cpuid_part, so fix building there.

(cherry picked from commit 30598a05385b0ac2380dd4f30037a9f9d0318cf2)
OpenWrt used to ship hardcoded defaults for lcp-echo-failure and
lcp-echo-interval in the non-uci /etc/ppp/options file.
These values break uci support for *disabling* LCP echos through
the use of "option keepalive 0" as either omitting the keepalive
option or setting it to 0 will result in no lcp-echo-* flags
getting passed to the pppd cmdline, causing the pppd process to
revert to the defaults in /etc/ppp/options.
Address this issue by letting the uci "keepalive" option default
to the former hardcoded values "5, 1" and by removing the fixed
lcp-echo-failure and lcp-echo-interval settings from the
/etc/ppp/options files.

Additionally rework the init script and update the default configuration

Finally drop the sed postinstall hack in uhttpd-mod-lua to avoid mangling

will only become active if both luci-base and uhttpd-mod-lua is installed.

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.

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

Apply IPv6/ND configuration before proto_send_update so that all config info
is available when netifd is handling the notify_proto ubus call.
In particular this fixes an issue when netifd is updating the downstream IPv6 mtu
as netifd was still using the not yet updated upstream IPv6 mtu to set the
downstream IPv6 mtu

Commit 4d961538f6 added libutil to the iproute2 InstallDev section
but lead to compile issues with packages picking up the wrong libutil
since libutil is quite a generic name ...
Further libutil is rather meant for internal usage in iproute2 than a
public API; therefore let's remove it from the InstallDev section together
with ll_map.h

In iproute2 v4.17 ll_map has been moved from the libnetlink to the libutil
library; add libutil as well to the staging dir in order to keep support

Fixes the annoying 'feature' were TTL was set to "1" by default ..
Users had to specify -T manually to test outside the own network.
2.0.12 change set (as of June 25th 2018)
o Change the unicast TTL default value from 1 to the system default (to be compatable with previous versions.) Multicast still defaults to 1.
o adpative formatting bug fix: crash occurs when values exceed 1 Tera. Add support for Tera and Peta and eliminate the potential crash condition
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
o fixes for windows cross compile (using mingw32)
o compile flags of -fPIE for android
o configure --enable-checkprograms to compile ancillary binaries used to test things such as delay, isoch, pdf generation
o compile tests when trying to use 64b seq numbers on a 32b platform
o Fix GCC ver 8 warnings

The call "get_features" allows to gather hostapd config options
via ubus. As first infos we add the ht and vht support.
Although nl80211 supports to gather informations about
ht and vht capabilities, the hostapd configuration can disable
vht and ht. However, it is possible that the iw output is not
representing the actual hostapd configuration.

Upstream renamed openssl-1.0.cnf to openssl-easyrsa.cnf.
However, pkg kept using openssl-1.0.cnf.
Upstream easyrsa searchs for vars, openssl-*, x509-types in the
same directory as easyrsa script. This was patched to revert
back to static /etc/easy-rsa/ directory (as does OpenSUSE).
EASYRSA_PKI still depends on $PWD.
Move easyrsa from /usr/sbin to /usr/bin as root is not needed.

iproute2's tc was updated to support the recently upstreamed cake qdisc.
Backport this canonical support from upstream into iproute2 v4.17
There is no kernel kmod/userspace tc ABI change in this release from the
previous package bump, so everyone can breath a sigh of relief.
This is largely a code style change, the exception to prove the rule:
option 'autorate_ingress' has been changed to 'autorate-ingress' to fit
in with upstream option naming expectations.
No openwrt package (e.g. sqm-scripts) has knowledge of
'autorate_ingress' thus only users who made their own scripts or used
it within the 'dangerous configuration' options of sqm-scripts will be
affected.

Add each variant to the matching PROVIDERS variables after evaluating
