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.

The '%m' conversion specifier prints an error message based on the current value of 'errno'. It is available in the GNU C library, Cygwin (since 2012), uClibc and musl. It is not available in various BSDs, BSD-derived systems (MacOS, Android) or Microsoft Windows. Use a symbol defined in platform.h to control how error messages can be formatted to display the 'errno' message. On platforms that support it use '%m'; on other platforms use '%s' and strerror(). On platforms that have '%m' there is essentially no change in the size of the binary.

2017-04-13su: FEATURE_SU_BLANK_PW_NEEDS_SECURE_TTYDenys Vlasenko
When this feature is enabled, blank passwords are not accepted by su unless the user is on a secure TTY defined in /etc/securetty. This resembles the default PAM configuration of some Linux distros which specify the nullok_secure option for pam_unix.so.

2017-03-16mount: create loop devices with LO_FLAGS_AUTOCLEAR flagDenys Vlasenko
The "autolooped" mount (mount [-oloop] IMAGE /DIR/DIR) always creates AUTOCLEARed loopdevs, so that umounting drops them (and this does not require any code in the umount userspace). This happens since circa linux-2.6.25: commit 96c5865559cee0f9cbc5173f3c949f6ce3525581 Date: Wed Feb 6 01:36:27 2008 -0800 Subject: Allow auto-destruction of loop devices IOW: in this case, umount does not have to use -d to drop the loopdev. The explicit loop mount (mount /dev/loopN /DIR/DIR) does not do this. In this case, umount without -d should not drop loopdev. Unfortunately, bbox umount currently always implies -d, this probably needs fixing. function old new delta set_loop 537 597 +60 singlemount 1101 1138 +37 losetup_main 419 432 +13 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/0 up/down: 110/0) Total: 110 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2017-01-24tls: add 2nd cipher_id, TLS_RSA_WITH_AES_128_CBC_SHA, so far it doesn't workDenys Vlasenko
Good news that TLS_RSA_WITH_AES_256_CBC_SHA256 still works with new code ;) This change adds inevitable extension to have different sized hashes and AES key sizes. In libbb, md5_end() and shaX_end() are extended to return result size instead of void - this helps *a lot* in tls (the cost is ~5 bytes per _end() function).

2017-01-23separate TLS code into a library, use in in wgetDenys Vlasenko
A new applet, ssl_client, is the TLS debug thing now. It doubles as wget's NOMMU helper. In MMU mode, wget still forks, but then directly calls TLS code, without execing. This can also be applied to sendmail/popmail (SMTPS / SMTP+starttls support) and nc --ssl (ncat, nmap's nc clone, has such option). function old new delta tls_handshake - 1691 +1691 tls_run_copy_loop - 443 +443 ssl_client_main - 128 +128 packed_usage 30978 31007 +29 wget_main 2508 2535 +27 applet_names 2553 2560 +7 ... xwrite_encrypted 360 342 -18 tls_main 2127 - -2127 ------------------------------------------------------------------------------ (add/remove: 4/1 grow/shrink: 13/8 up/down: 2351/-2195) Total: 156 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2017-01-09Allow FAST_FUNC to be overridden at build timeKang-Che Sung
Busybox uses FAST_FUNC macro to tweak with IA-32 calling conventions in order to make the function call slightly smaller or slightly faster. However, when I experiment with GCC's LTO (Link Time Optimization), I discovered that FAST_FUNC could hinder LTO's optimization so that the resulting executable become a few bytes larger (than what is compiled without FAST_FUNC). This change allows to specify e.g. CONFIG_EXTRA_CFLAGS="-DFAST_FUNC= -flto" and compile with LTO without a source code hack.
