2018-06-06restore documentation on the build config languageKartik Agaram
Kconfig-language.txt was deleted in commit 4fa499a17b52b back in 2006. Move to docs/ as suggested by Xabier Oneca: http://lists.busybox.net/pipermail/busybox/2014-May/080914.html Also update references to it everywhere.

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.

2017-08-08getopt32: remove applet_long_optionsDenys Vlasenko
FEATURE_GETOPT_LONG made dependent on LONG_OPTS. The folloving options are removed, now LONG_OPTS enables long options for affected applets: FEATURE_ENV_LONG_OPTIONS FEATURE_EXPAND_LONG_OPTIONS FEATURE_UNEXPAND_LONG_OPTIONS FEATURE_MKDIR_LONG_OPTIONS FEATURE_MV_LONG_OPTIONS FEATURE_RMDIR_LONG_OPTIONS FEATURE_ADDGROUP_LONG_OPTIONS FEATURE_ADDUSER_LONG_OPTIONS FEATURE_HWCLOCK_LONG_OPTIONS FEATURE_NSENTER_LONG_OPTS FEATURE_CHCON_LONG_OPTIONS FEATURE_RUNCON_LONG_OPTIONS They either had a small number of long options, or their long options are essential. Example: upstream addgroup and adduser have ONLY longopts, we should probably go further and get rid of non-standard short options. To this end, make addgroup and adduser "select LONG_OPTS". We had this breakage caused by us even in our own package! #if ENABLE_LONG_OPTS || !ENABLE_ADDGROUP /* We try to use --gid, not -g, because "standard" addgroup * has no short option -g, it has only long --gid. */ argv[1] = (char*)"--gid"; #else /* Breaks if system in fact does NOT use busybox addgroup */ argv[1] = (char*)"-g"; #endif xargs: its lone longopt no longer depends on DESKTOP, only on LONG_OPTS. hwclock TODO: get rid of incompatible -t, -l aliases to --systz, --localtime Shorten help texts by omitting long option when short opt alternative exists. Reduction of size comes from the fact that store of an immediate (an address of longopts) to a fixed address (global variable) is a longer insn than pushing that immediate or passing it in a register. This effect is CPU-agnostic. function old new delta getopt32 1350 22 -1328 vgetopt32 - 1318 +1318 getopt32long - 24 +24 tftpd_main 562 567 +5 scan_recursive 376 380 +4 collect_cpu 545 546 +1 date_main 1096 1095 -1 hostname_main 262 259 -3 uname_main 259 255 -4 setpriv_main 362 358 -4 rmdir_main 191 187 -4 mv_main 562 558 -4 ipcalc_main 548 544 -4 ifenslave_main 641 637 -4 gzip_main 192 188 -4 gunzip_main 77 73 -4 fsfreeze_main 81 77 -4 flock_main 318 314 -4 deluser_main 337 333 -4 cp_main 374 370 -4 chown_main 175 171 -4 applet_long_options 4 - -4 xargs_main 894 889 -5 wget_main 2540 2535 -5 udhcpc_main 2767 2762 -5 touch_main 436 431 -5 tar_main 1014 1009 -5 start_stop_daemon_main 1033 1028 -5 sed_main 682 677 -5 script_main 1082 1077 -5 run_parts_main 330 325 -5 rtcwake_main 459 454 -5 od_main 2169 2164 -5 nl_main 201 196 -5 modprobe_main 773 768 -5 mkdir_main 160 155 -5 ls_main 568 563 -5 install_main 773 768 -5 hwclock_main 411 406 -5 getopt_main 622 617 -5 fstrim_main 256 251 -5 env_main 198 193 -5 dumpleases_main 635 630 -5 dpkg_main 3991 3986 -5 diff_main 1355 1350 -5 cryptpw_main 233 228 -5 cpio_main 593 588 -5 conspy_main 1135 1130 -5 chpasswd_main 313 308 -5 adduser_main 887 882 -5 addgroup_main 416 411 -5 ftpgetput_main 351 345 -6 get_terminal_width_height 242 234 -8 expand_main 690 680 -10 static.expand_longopts 18 - -18 static.unexpand_longopts 27 - -27 mkdir_longopts 28 - -28 env_longopts 30 - -30 static.ifenslave_longopts 34 - -34 mv_longopts 46 - -46 static.rmdir_longopts 48 - -48 packed_usage 31739 31687 -52 ------------------------------------------------------------------------------ (add/remove: 2/8 grow/shrink: 3/49 up/down: 1352/-1840) Total: -488 bytes text data bss dec hex filename 915681 485 6880 923046 e15a6 busybox_old 915428 485 6876 922789 e14a5 busybox_unstripped Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
