Joakim Gebart 24d15ad9a5 core/net/ip: Prevent (tiny) buffer overflow in resolv_found()
An off-by-one error in resolv_found() could make an strncat() call
overflow by the terminating null byte.

When building with Clang the following warning was shown:

../../../core/net/ip/resolv.c:1458:17: warning: the value of the
      size argument in 'strncat' is too large, might lead to a
      buffer overflow [-Wstrncat-size]
                sizeof(resolv_hostname) - strlen(resolv_hostname));
                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../../../core/net/ip/resolv.c:1458:17: note: change the argument to
      be the free space in the destination buffer minus the
      terminating null byte
                sizeof(resolv_hostname) - strlen(resolv_hostname));
                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                sizeof(resolv_hostname) - strlen(resolv_hostname) - 1

Nicolas Tsiftes 4ce3e4dee8 Merge pull request #701 from tim-ist/routing_fix
Re-create a routing table entry if the next hop is changed.
2014-06-13 14:56:56 +02:00
Timofei Istomin 65ef375bdb Re-create a routing table entry if the next hop is changed.
The next-hop address did not get updated in the routing table
in case an entry for the destination already existed.

This patch resolves the issue by removing the entry and
having it re-created from scratch.

The issue causes a routing error triggering reconstruction of
the DODAG through version increase.

In case of somewhat frequent downward traffic in not (yet) stabilized DODAG
a vicious circle is formed: unstable topology means churn, downward
routing under churn causes reconstruction of DODAG. In this situation
the network does not have chance to stabilize.

We encountered a constant churn caused by this bug
in a network of 50 nodes and a periodic traffic (a packet every 5
seconds) generated at the root.
