2020-08-13build system: drop PLATFORM_LINUXRon Yorston
PLATFORM_LINUX is a hidden configuration option which is disabled by default and enabled at over a hundred locations for features that are deemed to be Linux specific. The only effect of PLATFORM_LINUX is to control compilation of libbb/match_fstype.c. This file is only needed by mount and umount. Remove all references to PLATFORM_LINUX and compile match_fstype.c if mount or umount is enabled. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2019-07-02libbb: reduce the overhead of single parameter bb_error_msg() callsJames Byrne
Back in 2007, commit 0c97c9d43707 ("'simple' error message functions by Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower overhead call to bb_perror_msg() when only a string was being printed with no parameters. This saves space for some CPU architectures because it avoids the overhead of a call to a variadic function. However there has never been a simple version of bb_error_msg(), and since 2007 many new calls to bb_perror_msg() have been added that only take a single parameter and so could have been using bb_simple_perror_message(). This changeset introduces 'simple' versions of bb_info_msg(), bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and bb_herror_msg_and_die(), and replaces all calls that only take a single parameter, or use something like ("%s", arg), with calls to the corresponding 'simple' version. Since it is likely that single parameter calls to the variadic functions may be accidentally reintroduced in the future a new debugging config option WARN_SIMPLE_MSG has been introduced. This uses some macro magic which will cause any such calls to generate a warning, but this is turned off by default to avoid use of the unpleasant macros in normal circumstances. This is a large changeset due to the number of calls that have been replaced. The only files that contain changes other than simple substitution of function calls are libbb.h, libbb/herror_msg.c, libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c, networking/udhcp/common.h and util-linux/mdev.c additonal macros have been added for logging so that single parameter and multiple parameter logging variants exist. The amount of space saved varies considerably by architecture, and was found to be as follows (for 'defconfig' using GCC 7.4): Arm: -92 bytes MIPS: -52 bytes PPC: -1836 bytes x86_64: -938 bytes Note that for the MIPS architecture only an exception had to be made disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h) because it made these files larger on MIPS.

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.

2017-01-09modprobe-small: optimizations for single applet buildExplorer09
(I'm requesting for a review first because I fear such an aggressive change could lead to bugs. While I observe the sizes have reduced, I haven't test the functionality of each applet after that. So please test before merging.) Aggressively cut off unneeded code when the relevant applets are not built. Correct dependencies of FEATURE_MODPROBE_SMALL_OPTIONS_ON_CMDLINE and FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED. Don't bother with the '-r' option check if only rmmod is built (assume true then), or when neither rmmod or mobprobe is built (assume false then).

2017-01-04modutils: remove special handling of uClibcWaldemar Brodkorb
Commit 3a45b87ac36f (modutils: support finit_module syscall) introduced macro finit_module. But it is not defined for uClibc. The compilation for busybox fails for MIPS with: With uClibc, we get following build errors: modutils/lib.a(modutils.o): In function `bb_init_module': modutils.c:(.text.bb_init_module+0x94): undefined reference to `finit_module' modutils.c:(.text.bb_init_module+0xa0): undefined reference to `finit_module' We can just use syscall() without any need for the uClibc wrappers. Newer versions of uClibc-ng (>1.0.20) will remove the module syscall wrappers.

2016-09-15modutils: support finit_module syscallMike Frysinger
On some systems like Chromium OS, loading modules from non-verified filesystems is denied. Only finit_module is allowed because an open fd is passed which can be checked against a verified location. Change the module loading code to first attempt finit_module and if that fails for whatever reason, fall back to the existing logic. On x86_64, this adds ~80 bytes to modutils/modutils.o and ~68 bytes to modutils/modprobe-small.o.
