Hmm, looks like both patches have similar functionality but with a bit
different approach. That patch doesn't exist when I decided to solve
that problem :). But there is always some time between decision and
implementation, especially when implementing it in spare time. OK, two
is better then zero, anyway :)
It doesn't matter, which of patches will be included, I think both are
acceptable. Main difference is that patch in tracker has
netsnmp_udp_{send,recv} functions redefined (so it has some code
duplication) while mine replaces recvfrom and sendto functions with
wrappers around recvmsg and sendmsg.
And, about the comments to above link, I think it should be default and
unconditional behaviour of any UDP server implementation to send replies
from address it received requests on. And it is not good that
implementation of this task is very OS-dependent :(
