#define	TTYMSG_IOV_MAX	32

const char	*ttymsg(struct iovec *, int, const char *, int);
- Move the prototype of ttymsg() into ttymsg.h. syslogd and talkd also use this, and they shouldn't have to have their own prototypes. - Silence warnings about constness and signedness in ttymsg(). This includes changing the return value to a `const char *', and changing the types of `left' and `wret' (both byte counts) to ssize_t.

Add RFC 5424 syslog message output to syslogd. - Move all of the code responsible for transmitting log messages into a separate function, fprintlog_write(). - Instead of manually modifying a list of iovecs, add a structure iovlist with some helper functions. - Alter the F_FORW (UDP message forwarding) case to also use iovecs like the other cases. Use sendmsg() instead of sendto(). - In the case of F_FORW, truncate the message to a size dependent on the address family (AF_INET, AF_INET6), as proposed by RFC 5426. - Move all traditional message formatting into fprintlog_bsd(). Get rid of some of the string copying and snprintf()'ing. Simply emit more iovecs to get the job done. - Increase ttymsg()'s limit of 7 iovecs to 32. Add a definition for this limit, so it can be reused by iovlist. - Add fprintlog_rfc5424() to emit RFC 5424 formatted log entries. - Add a "-O" command line option to enable RFC 5424 formatting. It would have been nicer if we supported "-o rfc5424", just like on NetBSD. Unfortunately, the "-o" flag is already used for a different purpose on FreeBSD. - Don't truncate hostnames in the RFC 5424 case, as suggested by that specific RFC. For people interested in using this, this feature can be enabled by adding the following line to /etc/rc.conf: syslogd_flags="-s -O rfc5424" Differential Revision: https://reviews.freebsd.org/D15011 2018-04-15 08:34:16 +00:00			`#define TTYMSG_IOV_MAX 32`
