* Use pcap_findalldevs() when available instead of pcap_lookupdev()Thomas Habets2019-11-072-1/+48
| | | | This change is only used when using -F.
* Switch from rand() to random()Thomas Habets2019-11-011-1/+1
| | | | | random() has better pseudorandom promises. Not that we need it for security, but why not use the better one since it exists.

|
* Remove all read permissions with unveil(2)Thomas Habets2019-07-311-2/+2
|
* Use unveil(2) and pledge(2) to drop more privileges, where availableThomas Habets2019-07-312-1/+41
| | | | | | | | | | | | | Only available on OpenBSD as far as I know. pledge(2): Strangely there doesn't seem to be a way to use many of the ioctls needed during setup, so pledge(2) only protects the main loop. unveil(2): Strangely there doesn't seem to be a way of just dropping all fs access. Instead I restricted to only reading what is probably a nonexistent file.
* Increase shell compat of configure.acThomas Habets2019-07-311-1/+1

* Fix false duplicates in edge conditionThomas Habets2019-04-192-4/+38
| | | | | | | | | | | | | | | | | | | | | We still have duplicates when pinging in promisc mode, if someone else is arping at the same time. It's assumed that arping in promisc mode is rare, and that in either case what we're interested in then is the reply, no matter what the reason was for it being sent. This is to solve a problem where even if not using promisc mode we'll see replies going *out* of localhost. This fix assumes that default desired behaviour when arpinging local host is to not get replies from local host, only from remote hosts. Default behavour, after this commit, uses the model of request and reply as best it can (localhost will never request from itself, and will actually not even reply to it). It therefore doesn't work well if the *actual* question is "is this IP address taken", because if the answer is "yes, by localhost" the answer is now "no", whereas before this commit it was *unreliably* sometimes "yes". Fixes #32
* _BSD_SOURCE->_DEFAULT_SOURCE as the former is deprecatedThomas Habets2019-01-061-1/+1

* Compile without any warning hardened and with C99Thomas Habets2019-01-067-21/+72
| | | | | | | | | E.g.: `./configure CC=c99 --enable-hardened --enable-warnings` Test code not yet warning-free. Hardening output can be checked with `hardening-check`

* Provide configure-time fallback for cross-compile checksThomas Habets2017-10-011-3/+6
| | | | | | | The checks are pretty much entirely compile-time checks, so providing a likely default if running is skipped should be safe. bugs.debian.org/877402
