Bug 23013

configure misdetects source address checking method and compilation fails.

The following patch + running autoconf helps.

fix configure.in to detect findsaddr-linux method

Somewhat related to #22254.

I've merged non-{aliases,autoroute*} (the implementation has changed, so these might need a 
little more thought) patches against the newer version, sanitizing them a bit in the process.

The patches are as follows:

traceroute-1.4a11-configure.patch
 * contains the first configure-linux patch and required stuff
 * fixes the need for gcc detection in configure properly
 * fixes the default to detect linux kernel route table checking with /proc
 * replaces the most of  traceroute-1.4a5-fix.patch

traceroute-1.4a11-droproot.patch
 * drop root earlier (no major changes)
 * XXX: useicmp is used before it's defined, well, it was wrong in the past.  
Nonetheless icmp/udp seem to work.

traceroute-1.4a11-redhat.patch
 * Fix Makefile.in
 * replaces traceroute-1.4a5-{fhs,fhs}.patch

traceroute-1.4a11-secfix.patch
 * get IFNAMSIZ directly from net/if.h
 * replace 'Nice try' etc. with more informative messages from traceroute-1.4a5-lsrr.patch
 * replace old secfix

traceroute-1.4a11-ANK.patch
 * last bits from traceroute-1.4a5-lsrr.patch that weren't already in 

traceroute-1.4a5-unaligned.patch
 * unchanged

"Obsolete" patches:
traceroute-1.4a5-llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.patch
 * MAXHOSTNAMELEN was back to 64 in lsrr anyway.  Should get shorter hostnames, this
is making standard headers sick

traceroute-1.4a5-bigpacklen.patch
 * no longer needed

traceroute-1.4a5-sourceroute.patch
 * no longer needed, savestr has been killed

traceroute-1.4a5-alpha.patch
 * should not be needed any longer

Nonmerged, at least yet (a little different approach now):

traceroute-1.4a5-aliases.patch
traceroute-1.4a5-autoroute.patch
traceroute-1.4a5-autoroute2.patch

tracerouting via aliased interfaces (with -s) seems rebroken without some of 
those patches, at least.

http://www.netcore.fi/pekkas/linux/

Clarification: limited testing seems to show that '-s' w/ aliased interfaces (or using -i eth0:x) works.  
Automatical detection doesn't.  Basic dual-interface configuration also works.

The aliased interfaces patch seemed to break some P-t-P configurations (#17915) so I'm 
not sure if that solution is a good one. .. or even really needed that much.

I have updated these for traceroute-1.4a12 (very minor configuration patch), and split the ANK patch to two,
where the latter part isn't applied by default.  There are new methods in effect now.

Also, I've included a patch for -i so that the interface will actually be always used too.  This applies to 1.4a5
as well.  Attaching this one.

Every scenario I can think of (aliased interfaces, multihomed systems, ...) would appear to work with this one.
Feedback welcome.

The rest can be found in the URL mentioned above.

really use the interface with -i

Note: a12 has been released too.  .src.rpm is available at
http://www.netcore.fi/pekkas/linux/.

Anything new on this one?  I'd like to see a new version in the next release.

It's on my list of packages to be updated or the next upcoming release.

Thanks for the info.

Read ya, Phil
