* implement xferstats. full stats are displayed for `STAT', and a
summary is displayed upon exit (and syslogged). inspired by wu-ftpd.
* wrap data xfers in {send,receive}_data with alarm() timeouts. this
should remove the majority of the `hanging ftpd' problems that
people were still seeing. inspired by wu-ftpd.
* link with ../../bin/ls, so that bin/ls is not required under a
chroot()ed area for `LIST' to work. based on [bin/4497] from
"Soren S. Jorvang" <soren@t.dk>
* migrate code from util.c into ftpd.c, so that it doesn't conflict
with ls' util.c.
* remove man page comment about ~ftp/bin/ls being necessary.
* bump version to 7.2.0.
* syslog xfer time with xfer stats.
* if appropriate, syslog error message with command.
internal code stuff:
* change arguments of various functions from `char *' to `const char *'.
* define PLURAL(x) macro, which returns `' if x == 1, `s' otherwise.
use macro appropriately
* lreply(): a code of -1 means ``send line as is''. a code of 0
means ``send line with 4 space prefix''. don't print a space after
the `-' for any other code.
* logcmd(): add `const struct timeval *elapsed' and `const char *error'
for more flexible error reporting
This allows other programs to link in against ls (e.g, ftpd), without having
to have hacks to deal with multiple main()s.
Yes, I know this is ugly. The clean alternative (move lots of this
into libutil, yada yada yada) isn't fun, and the effort probably isn't
justified...
qualifiers are DLT_SLIP and DLT_PPP (i.e. old-style serial encap PPP).
If an attempt to use these qualifiers is used for any other link type,
cause a BPF program compilation error.
serious race condition in sosend(). Upon closer inspection, the appropriate
flags are checked within splsoftnet() for soreceive(), so no change needed
there. Also a little KNFing in sosend().
headaches.
Now console keyboard and display are connected at autoconfiguration time,
when the last of them is found. Other keyboards / displays remain
unconnected until a new ioctl (WSDISPLAYIO_SETKEYBOARD) is called.
