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>

2018-11-01ash: allow shell scripts to be embedded in the binaryDenys Vlasenko
To assist in the deployment of shell scripts it may be convenient to embed them in the BusyBox binary. 'Embed scripts in the binary' takes any files in the directory 'embed', concatenates them with null separators, compresses them and embeds them in the binary. When scripts are embedded in the binary, scripts can be run as 'busybox SCRIPT [ARGS]' or by usual (sym)link mechanism. embed/nologin is provided as an example. function old new delta packed_scripts - 123 +123 unpack_scripts - 87 +87 ash_main 1103 1171 +68 run_applet_and_exit 78 128 +50 get_script_content - 32 +32 script_names - 10 +10 expmeta 663 659 -4 ------------------------------------------------------------------------------ (add/remove: 4/0 grow/shrink: 2/1 up/down: 370/-4) Total: 366 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2018-10-31libbb/u_signal_names.c: don't check errno after bb_strtouRasmus Villemoes
Since we're comparing the return value to a smallish integer anyway, we might as well use that bb_strtou() returns UINT_MAX for malformed input. Referencing errno is kinda bloaty on glibc. While NSIG is not in POSIX, we do already rely on it being defined, compile-time const and smallish, since arrays in struct globals_misc are defined in terms of it. function old new delta get_signum 312 286 -26 Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2018-10-31libbb: optionally honour libc provided SIGRTMIN/SIGRTMAX in get_signum()Rasmus Villemoes
When an application documents that it responds such and such to SIGRTMIN+n, that almost always means with respect to the libc-provided SIGRTMIN. Hence I disagree with the "more correct" in commit 7b276fc17594. In any case, this is rather unfortunate: 36 34 (the first shell is bash). We probably can't change default behaviour after 7 years, but at least we can provide a config option. We avoid a little code generation (repeated calls to __libc_current_sigrtmin) by stashing SIGRTMIN/SIGRTMAX in local variables, but it does cost ~50 bytes. The next patch serves as penance for that.

2018-09-09remove_file: don't call rmdir if remove_file return failureChen Yu
When deleting a directory, the directory should not be removed if the file in the subdirectory fails to be deleted. Background information: When I tested the kernel using LTP (linux-test-project).I found the mv command have some issue. The LTP test case use the mv command to move the directory t1 in the cgroup file system to the /tmp directory. becase files in the cgroup file system are not allowed to be removed. so the mv reported "Permission denied", but I used the ls command to view the results and found that the directory t1 had been removed from the cgroup file system. For the same test case, I used the mv tool in the GNU coreutils, and the directory t1 will not be removed. the following testcase use busybox mv: / # mount -t cgroup -o cpu cgroup /cpu / # cd /cpu /cpu # mkdir -p t1 /cpu # ls cgroup.clone_children cpu.cfs_period_us cpu.stat t1 cgroup.procs cpu.cfs_quota_us notify_on_release tasks cgroup.sane_behavior cpu.shares release_agent /cpu # mv t1 /tmp mv: can't remove 't1/cgroup.procs': Operation not permitted mv: can't remove 't1/cpu.cfs_period_us': Operation not permitted mv: can't remove 't1/cpu.stat': Operation not permitted mv: can't remove 't1/cpu.shares': Operation not permitted mv: can't remove 't1/cpu.cfs_quota_us': Operation not permitted mv: can't remove 't1/tasks': Operation not permitted mv: can't remove 't1/notify_on_release': Operation not permitted mv: can't remove 't1/cgroup.clone_children': Operation not permitted /cpu # ls cgroup.clone_children cpu.cfs_period_us cpu.stat cgroup.procs cpu.cfs_quota_us notify_on_release tasks cgroup.sane_behavior cpu.shares release_agent /cpu # This patch fixed it, don't call rmdir if remove_file return failure, and under certain file systems, the mv could work normally.

This necessitates switch from libc FILE api to a simple homegrown replacement. The change which fixes the bug here is the deleting of restore_redirected_FILEs(); line. It was prematurely moving (restoring) script fd#3. The fix is: we don't even _want_ to restore scrit fds, we are perfectly fine with them being moved. The only reason we tried to restore them is that FILE api did not allow moving of FILE->fd. function old new delta refill_HFILE_and_getc - 93 +93 hfopen - 90 +90 hfclose - 66 +66 pseudo_exec_argv 591 597 +6 hush_main 1089 1095 +6 builtin_source 209 214 +5 save_fd_on_redirect 197 200 +3 setup_redirects 320 321 +1 fgetc_interactive 235 236 +1 i_peek_and_eat_bkslash_nl 99 97 -2 expand_vars_to_list 1103 1100 -3 restore_redirects 99 52 -47 fclose_and_forget 57 - -57 remember_FILE 63 - -63 ------------------------------------------------------------------------------ (add/remove: 3/2 grow/shrink: 6/3 up/down: 271/-172) Total: 99 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
