- fix displayed version string (problem from github tarball).
- add a new _mtr user
- drop mtr-packet to _mtr rather than to getgid()/getuid()
- chroot to /var/empty
- shiny new DNS code that gets rid of the horrible libbind hack.
- the privileged packet sending code has been split out into a separate
"mtr-packet" process with a clear separation between init/main code, which
communicates with the main mtr process over a pipe.
Patch to add a pledge to mtr-packet, currently disabled; it works for
ICMP but requires additional sockopts to work with UDP.
so rename the current no_x11 flavour to the default (with @pkgpath to
allow updates to work), rename what was the default flavour to gtk and
mark that broken. maintainer timeout.
