[PATCH] gweb: fix crash on malformed http response
by Mans Rullgard
If an http response has a line starting with whitespace before the first
valid header field, g_hash_table_lookup() is called with a null key,
which is invalid. Fix this by checking for a valid last_key before
attempting to process continuation lines.

FW: [PATCH] dhcp: Follow the RFC regarding ordrer of "subnet" and "router" option
by Kristian Klausen
Resending because it seems like I need to be subscribed, before I can post.
and it impossible to get in contact with any Connman dev (which could check the mail, and allow it to be posted).. At least on #connman on freenode.

[PATCH 0/1] Fix nameserver and search domain ordering when writing resolv.conf
by Sam Nazarko
Hi,
This patch fixes an issue where DNS servers and search domains are written to
resolv.conf in the reverse order. This has caused problems with some OSMC users that
have relied on the primary DNS server to be listed first and have a faulty or intermittent
secondary DNS server. While I am in agreement that these users should fix their secondary
DNS server, we should still respect the ordering that they configure or get via DHCP.
I previously submitted a patch to this mailing list in hope of addressing an issue
however the ConnMan mailing list disappeared for a while and I lost my post. This
new patch resolves both search domains and DNS servers being out of order.

[PATCH] service: Use PreferredTechnologies for service ordering
by Maxime Chevallier
When services have the same state, the PreferredTechnologies list needs
to be taken into account for service ordering. This applies when all
services are 'ready' but none is 'online'.
This patch checks for services in PreferredTechnologies before
defaulting to the hardcoded list in service_compare.

[PATCH v0 0/3] nftable session fixes
by Daniel Wagner
From: Daniel Wagner <daniel.wagner(a)bmw-carit.de>
Hi,
The first patch removes the connection tracking code from ConnMan. We
never really used it. It looks like we are soon having means to
enforce network activies via cgroups (eBPF) thanks to Daniel Macks
work [1]. So I think its better to have this kind of enforcement in an
external component.
The second patch does add a warning when nftables fails. It took me a
while to figure out what's going on when I forgot to load the right
module. So why not just be userfriendly.
The last patch moves the marking rule to the route table. I just
placed it iniatially into the filter chain. That was wrong. With this,
the packets are routed acording the session settings.
cheers,
daniel
