2016-07-22config: disentangle PREFER_APPLETS from SH_STANDALONE and SH_NOFORKDenys Vlasenko
On user request. I thought enabling/disabling them all together is more consistent. Evidently, some people do want them to be separately selectable. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2016-03-30applet_tables: save space by removing applet name offsetsRon Yorston
The array applet_nameofs consumes two bytes per applet. It encodes nofork/noexec flags suid flags the offset of the applet name in the applet_name string Change the applet_table build tool to store the flags in two separate arrays (applet_flags and applet_suid). Replace applet_nameofs[] with a smaller version that only stores a limited number of offsets. This requires changes to the macros APPLET_IS_NOFORK, APPLET_IS_NOEXEC and APPLET_SUID. According to Valgrind the original find_applet_by_name required 353 cycles per call, averaged over all names. Adjusting the number of known offsets allows space to be traded off against execution time: KNOWN_OFFSETS cycles bytes (wrt KNOWN_OFFSETS = 0) 0 9057 - 2 4604 32 4 2407 75 8 1342 98 16 908 130 32 884 194 This patch uses KNOWN_OFFSETS = 8. v2: Remove some dead code from the applet_table tool; Treat the applet in the middle of the table as a special case. v3: Use the middle applet to adjust the start of the linear search as well as the last applet found. v4: Use an augmented linear search in find_applet_by_name. Drop the special treatment of the middle name from get_applet_name: most of the advantage now derives from the last stored value. v5: Don't store index in applet_nameofs, it can be calculated. v6: Tweaks by Denys function old new delta find_applet_by_name 25 125 +100 applet_suid - 92 +92 run_applet_no_and_exit 452 460 +8 run_applet_and_exit 695 697 +2 applet_name_compare 31 - -31 applet_nameofs 734 14 -720 ------------------------------------------------------------------------------ (add/remove: 1/1 grow/shrink: 3/1 up/down: 202/-751) Total: -549 bytes text data bss dec hex filename 925464 906 17160 943530 e65aa busybox_old 924915 906 17160 942981 e6385 busybox_unstripped Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2013-07-26buildsys: Add helper to list suid appletsBernhard Reutner-Fischer
Add a helper script that lists all applets that - do or may require SUID provileges (busybox.cfg.suid) - do not require SUID provileges (busybox.cfg.nosuid) Some setups prefer to build two busybox binaries, one that is suid which contains all applets that do or may require suid privileges, and a second one for all the rest (which drops suid). To ease splitting these two binaries, generate a list of CONFIG_ items for the suid binary. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
