* Sprinkle const.
* Use EXIT_FAILURE instead of 1.
* Use err(), errx().
* Use calloc() instead of malloc()+memset().
* timedc:
* Non-terminated hostnames or unknown tsp_type could
cause a crash due to out-of-bounds reads in msite().
* Check the received packet size.
* Merged duplicated code into functions.
* Moved variables into the relevant scopes.
* Use connect() so that only the receiver can reply,
send()/recv() can be used and rejected packets
are immediately noticed by recv() instead of causing
timeouts.
* Updated manpage.
use of a raw socket for ICMP; thus there is also no need to differ
between privileged and unprivileged commands.
* Switch to user "nobody" after allocating the raw socket.
* Close all file descriptors above 2 (just in case).
* Check the packet size and sender address in daydiff().
* priv_resources(): Use bind() instead of bindresvport() because an
reserved port is not required. This also resolves the interoperability
issue reported in PR bin/35479.
* Replaced most strlcpy() with set_tsp_name() and get_tsp_name() because
strlcpy() could potentially run out-of-bounds and doesn't zero out
unused buffer space.
* Replaced bcopy/bzero() with memcpy/memset().
* Fixed potential alignment/aliasing issues in measure().
* Replace u_short/u_long with uint16_t/uint32_t/in_addr_t where appropriate.
* Renamed sin to addr because sin is a reserved identifier.
* Use bindresvport() instead of looping over bind(); rresvport() returns
a SOCK_STREAM socket not SOCK_DGRAM.
code considerably and was mainly providing SGI specific logging facilities
and some hacks to improve the relyablility on SGI systems by increasing
priorities etc...
- ensure hostname from gethostname() is nul-terminated in all cases
- minor KNF
- use MAXHOSTNAMELEN over various other values/defines
- be safe will buffers that hold hostnames
