Update busybox to version 1.36.0 * refresh patches (remove the backported upstream fix) * refresh config Config refresh: Refresh commands, run after busybox is first built once: cd package/utils/busybox/config/ ../convert_menuconfig.pl ../../../../build_dir/target-arm_cortex-a15+neon-vfpv4_musl_eabi/busybox-default/busybox-1.36.0 cd .. ./convert_defaults.pl ../../../build_dir/target-arm_cortex-a15+neon-vfpv4_musl_eabi/busybox-default/busybox-1.36.0/.config > Config-defaults.in Manual edits needed after config refresh: * Config-defaults.in: OpenWrt config symbol IPV6 logic applied to BUSYBOX_DEFAULT_FEATURE_IPV6 * Config-defaults.in: OpenWrt config TARGET_bcm53xx logic applied to BUSYBOX_DEFAULT_TRUNCATE (commit547f1ec) * Config-defaults.in: OpenWrt logic applied to BUSYBOX_DEFAULT_LOGIN_SESSION_AS_CHILD (commitdc92917) * Config-defaults.in: correct the default ports that get reset BUSYBOX_DEFAULT_FEATURE_HTTPD_PORT_DEFAULT 80 BUSYBOX_DEFAULT_FEATURE_TELNETD_PORT_DEFAULT 23 * config/editors/Config.in: Add USE_GLIBC dependency to BUSYBOX_CONFIG_FEATURE_VI_REGEX_SEARCH (commitf141090) * config/shell/Config.in: change at "Options common to all shells" the conditional symbol SHELL_ASH --> BUSYBOX_CONFIG_SHELL_ASH (discussion in http://lists.openwrt.org/pipermail/openwrt-devel/2021-January/033140.html Apparently our script does not see the hidden option while prepending config options with "BUSYBOX_CONFIG_" which leads to a missed dependency when the options are later evaluated.) * Edit a few Config.in files by adding quotes to sourced items in config/Config.in, config/networking/Config.in and config/util-linux/Config.in (commit1da014f) Signed-off-by: Hannu Nyman <hannu.nyman@iki.fi>

|
|
help
|
|
One common problem reported on the mailing list is the "can't
|
|
access tty; job control turned off" error message, which typically
|
|
appears when one tries to use a shell with stdin/stdout on
|
|
/dev/console.
|
|
This device is special - it cannot be a controlling tty.
|
|
|
|
The proper solution is to use the correct device instead of
|
|
/dev/console.
|
|
|
|
cttyhack provides a "quick and dirty" solution to this problem.
|
|
It analyzes stdin with various ioctls, trying to determine whether
|
|
it is a /dev/ttyN or /dev/ttySN (virtual terminal or serial line).
|
|
On Linux it also checks sysfs for a pointer to the active console.
|
|
If cttyhack is able to find the real console device, it closes
|
|
stdin/out/err and reopens that device.
|
|
Then it executes the given program. Opening the device will make
|
|
that device a controlling tty. This may require cttyhack
|
|
to be a session leader.
|
|
|
|
Example for /etc/inittab (for busybox init):
|
|
|
|
::respawn:/bin/cttyhack /bin/sh
|
|
|
|
Starting an interactive shell from boot shell script:
|
|
|
|
setsid cttyhack sh
|
|
|
|
Giving controlling tty to shell running with PID 1:
|
|
|
|
# exec cttyhack sh
|
|
|
|
Without cttyhack, you need to know exact tty name,
|
|
and do something like this:
|
|
|
|
# exec setsid sh -c 'exec sh </dev/tty1 >/dev/tty1 2>&1'
|
|
|
|
Starting getty on a controlling tty from a shell script:
|
|
|
|
# getty 115200 $(cttyhack)

This option causes busybox shells to use busybox applets
|
|
in preference to executables in the PATH whenever possible. For
|
|
example, entering the command 'ifconfig' into the shell would cause
|
|
busybox to use the ifconfig busybox applet. Specifying the fully
|
|
qualified executable name, such as '/sbin/ifconfig' will still
|
|
execute the /sbin/ifconfig executable on the filesystem. This option
|
|
is generally used when creating a statically linked version of busybox
|
|
for use as a rescue shell, in the event that you screw up your system.
|
|
|
|
This is implemented by re-execing /proc/self/exe (typically)
|
|
with right parameters.
|
|
|
|
However, there are drawbacks: it is problematic in chroot jails
|
|
without mounted /proc, and ps/top may show command name as 'exe'
|
|
for applets started this way.

help
|
|
This option causes busybox shells to not execute typical
|
|
fork/exec/wait sequence, but call <applet>_main directly,
|
|
if possible. (Sometimes it is not possible: for example,
|
|
this is not possible in pipes).
|
|
|
|
This will be done only for some applets (those which are marked
|
|
NOFORK in include/applets.h).
|
|
|
|
This may significantly speed up some shell scripts.
|
|
|
|
This feature is relatively new. Use with care. Report bugs
|
|
to project mailing list.

Allow scripts to be compressed and embedded in the busybox

binary. The scripts should be placed in the 'embed' directory
|
|
at build time. Like applets, scripts can be run as
|
|
'busybox SCRIPT ...' or by linking their name to the binary.
|
|
|
|
This also allows applets to be implemented as scripts: place
|
|
the script in 'applets_sh' and a stub C file containing
|
|
configuration in the appropriate subsystem directory.
