Simplify and unify wording for the -I sourceaddr option in various places.

This is somewhat related to the "-b bind_addr" option some programs have, which should get some cleanup also... input florian claudio jmc

ping(8): improve "-i wait" parsing and error-checking code

2020-01-04T01:00:18Z

- Never accept negative values. - Cap the interval at UINT_MAX seconds to avoid strange rounding behavior at the end of the input range. - Use error messages that resemble other parts of the tree where we are able to use strtonum(3). - Leverage modf(3) for cleaner code. - Call it "-i interval" to avoid accidental visual similarity to "-w maxwait". With input from cjeker@, kettenis@, kn@. ok kn@

implausible bug existed in the socket setup (mostly dns-related and setsockopt) it would be largely neutered. of course, a very restrictive pledge is installed soon after that... ok mestre brynet florian

ping(8): don't round inter-packet delay up to HZ

2019-07-20T00:49:54Z

ping(8) doesn't know the value of HZ and shouldn't round the user's packet wait up to whatever it thinks HZ is. If the period is too small the interrupt will simply fire less often than instructed. The kernel will do the right thing regardless. Given the rarity of this usage we don't really need to print a warning, either. ok millert@

When system calls indicate an error they return -1, not some arbitrary

value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

delay dropping privs a bit when root so that setrtable works.

make all the setsockopt calls consistent.

do not cast the arguments unnecessarily, and always err() on failure. an earlier diff just tweaking the v6 calls was oked by bluhm@ kn@ deraadt@

let -D work on ping6 too.

add support for setting the traffic class on ipv6 packets.

2018-11-10T05:03:23Z

it reuses the toskeyword handling that ipv4 uses for setting the tos field, which is equiavlent to traffic class. ok florian@ denis@
