2018-11-27hush: allow hush to run embedded scriptsRon Yorston
Embedded scripts require a shell to be present in the BusyBox binary. Allow either ash or hush to be used for this purpose. If both are enabled ash takes precedence. The size of the binary is unchanged in the default configuration: both ash and hush are present but support for embedded scripts isn't compiled into hush.

2018-11-17Treat custom and applet scripts as appletsRon Yorston
BusyBox has support for embedded shell scripts. Two types can be distinguished: custom scripts and scripts implementing applets. Custom scripts should be placed in the 'embed' directory at build time. They are given a default applet configuration and appear as applets to the user but no further configuration is possible. Applet scripts are integrated with the BusyBox build system and are intended to be used to ship standard applets that just happen to be implemented as scripts. They can be configured at build time and appear just like native applets. Such scripts should be placed in the 'applets_sh' directory. A stub C program should be written to provide the usual applet configuration details and placed in a suitable subsystem directory. It may be helpful to have a configuration option to enable any dependencies the script requires: see the 'nologin' applet for an example. function old new delta scripted_main - 41 +41 applet_names 2773 2781 +8 applet_main 1600 1604 +4 i2cdetect_main 672 674 +2 applet_suid 100 101 +1 applet_install_loc 200 201 +1 applet_flags 100 101 +1 packed_usage 33180 33179 -1 tryexec 159 152 -7 evalcommand 1661 1653 -8 script_names 9 - -9 packed_scripts 123 114 -9 complete_cmd_dir_file 826 811 -15 shellexec 271 254 -17 find_command 1007 990 -17 busybox_main 642 624 -18 run_applet_and_exit 100 78 -22 find_script_by_name 51 - -51 ------------------------------------------------------------------------------ (add/remove: 1/2 grow/shrink: 6/9 up/down: 58/-174) Total: -116 bytes text data bss dec hex filename 950034 477 7296 957807 e9d6f busybox_old 949918 477 7296 957691 e9cfb busybox_unstripped Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2018-05-13nsenter: fix parsing of -t, -S and -G optionsEuan Harris
-t, -S and -G each take mandatory integer arguments. getopt32long()'s option string syntax for this type of argument is 'c:+', however nsenter's opt_str uses 'c+', which specifies two options 'c' and '+' which do not take arguments. This means that giving a target PID causes nsenter to exit and print the usage string: # nsenter -t1 sh nsenter: unrecognized option: 1 BusyBox v1.27.2 (2017-12-12 10:41:50 GMT) multi-call binary. ... The long form options are also broken: # nsenter --setuid=1000 --setgid=1000 sh BusyBox v1.29.0.git (2018-05-04 13:56:49 UTC) multi-call binary. ... `nsenter --target=<pid> sh` parses correctly and appears to work, but <pid> is ignored and set to 0. This doesn't raise an error unless one of the namespace arguments is also given: # ./busybox_unstripped nsenter --target=42 sh # exit # ./busybox_unstripped nsenter -n --target=42 sh BusyBox v1.29.0.git (2018-05-04 13:56:49 UTC) multi-call binary. ... This has caused problems in a couple of places: https://github.com/linuxkit/linuxkit/issues/567 https://github.com/gliderlabs/docker-alpine/issues/359 https://github.com/kontena/pharos-cluster/pull/81 Signed-off-by: Euan Harris <euan.harris@docker.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2018-05-13nsenter: Rename --network option to --netEuan Harris
In nsenter from util-linux, the long version of the -n option is --net=<path>. BusyBox's version expects --network=<path>, so scripts and examples written for util-linux's version cause BusyBox's version to exit with the usage message. Confusingly, until commit 036585a911a5f, the usage message erroneously claimed that the long option was indeed called --net; after that commit long options are not listed at all.

Add support for LittleFS to blkid. Not included if FEATURE_BLKID_TYPE is not selected (neither UUID nor label). LittleFS is a small fail-safe filesystem designed for embedded systems. It has strong copy-on-write guarantees and storage on disk is always kept in a valid state. It also provides a form of dynamic wear levelling for systems that can not fit a full flash translation layer. (https://github.com/geky/littlefs) ARM has introduced it in its Mbed OS 5.7, so it starts to gain focus.
