-Subject: [PATCH] olsrd: fix stack corruption in net_output()
-
-The net_output() function indirectly uses the stack variables dst and dst6
-outside of the scope they're declared in, this might leads to olsr_sendto()
-being called with a corrupted destination sockaddr_in.
-
-This failure condition can be observed in the log, olsrd will continuosly
-print "sendto(v4): Invalid Argument" or a similar message. On ARM it has been
-reported to result in "Unsupported Address Family".
-
-This bug became apparant on a custon OpenWrt x86_64 uClibc target using the
-Linaro GCC 4.7-2012.04 compiler, it has been reported for an unspecified ARM
-target as well.
-
-The offending code seems to be unchanged since 2008 and it does not cause
-issues on 32bit systems and/or with older (Linaro) GCC versions, but the
-compiler used in our tests seems to perform more aggressive optimizations
-leading to a stack corruption.
