Busybox already uses sendfile in httpd. This patch proposes to use it globally to copy data between file descriptors. It speeds up the copying on slow systems a lot - below are the times needed to copy a 450Mb file with and without this option enabled on a BeagleBone Black: sendfile: user 0m0.000s sys 0m8.170s read/write 4k: user 0m0.470s sys 0m16.300s function old new delta bb_full_fd_action 394 474 +80 Signed-off-by: Bartosz Golaszewski <bartekgola@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

precedes IPv4 one in DNS reply, busybox network applets

Note that for busybox telnetd to work you need several things:
|
|
First of all, your kernel needs:
|
|
UNIX98_PTYS=y
|
|
DEVPTS_FS=y
|
|
|
|
Next, you need a /dev/pts directory on your root filesystem:
|
|
|
|
$ ls -ld /dev/pts
|
|
drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/
|
|
|
|
Next you need the pseudo terminal master multiplexer /dev/ptmx:
|
|
|
|
$ ls -la /dev/ptmx
|
|
crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
|
|
|
|
Any /dev/ttyp[0-9]* files you may have can be removed.
|
|
Next, you need to mount the devpts filesystem on /dev/pts using:
|
|
|
|
mount -t devpts devpts /dev/pts
|
|
|
|
You need to be sure that busybox has LOGIN and
|
|
FEATURE_SUID enabled. And finally, you should make
|
|
certain that Busybox has been installed setuid root:
|
|
|
|
chown root.root /bin/busybox
|
|
chmod 4755 /bin/busybox
|
|
|
|
with all that done, telnetd _should_ work....

help

This option allows you to run telnetd in "inet wait" mode.
|
|
Example inetd.conf line (note "wait", not usual "nowait"):
|
|
|
|
telnet stream tcp wait root /bin/telnetd telnetd -w10
|
|
|
|
In this example, inetd passes _listening_ socket_ as fd 0
|
|
to telnetd when connection appears.
|
|
telnetd will wait for connections until all existing
|
|
connections are closed, and no new connections
|
|
appear during 10 seconds. Then it exits, and inetd continues
|
|
to listen for new connections.
|
|
|
|
This option is rarely used. "tcp nowait" is much more usual
|
|
way of running tcp services, including telnetd.
|
|
You most probably want to say N here.
