2018-07-31install.sh: don't clobber dangling symlinksBaruch Siach
Symlinks in a subdirectory that is to become target rootfs are sometimes dangling because they link to canonical file names that are not present on the host, but are present relative to the target rootfs root. Don't copy over dangling symlinks when noclobber is enabled The -e test treats dangling symlinks as non-existent files. Add -h test that returns true for all symlinks. Cc: Yann E.

2018-04-15applets/install: don't try to install nothingYann E. MORIN
Commit 952d5a6024e7 (applets/install: accept more than one install option) changed the way we handle install options: before that commit, a missing install type would mean to install nothing; after, we would iterate over options, so we would never notice there was a mising option. Fix that by introducing an explicit --none option to specify to install nothing.

2018-04-14build system: fix parallel building issueMichael Olbrich
The files generated by the include/config/MARKER target are in the dependency list for applets/applet_tables. If applets/applet_tables is created first during applets_dir then it will be created again later as part of $(busybox-dirs). As a result include/applet_tables.h is created again. This time while other build commands may need it. Let applets_dir depend on include/config/MARKER to avoid this particular race condition and create the header files atomically to ensure that the compiler never sees incomplete files.

2018-02-23Fix install with hardlinks and a custom PREFIX. Closes 10801Denys Vlasenko
Trying to install busybox with hardlinks and a custom PREFIX will fail for applets not in the /bin directory, because relative pathnames are used. applets/install.sh is *supposed to* use the absolute pathname for hardlinks but it fails to do so because the wrong check is used in the if statement. While fixing it, shore up other sloppy coding in applets/install.sh Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2018-01-04applets/install: accept more than one install optionYann E. MORIN
Currently, it is impossible to pass more than one option to the isntall script, so it totally prevents using --noclobber. Signed-off-by: Yann E. MORIN <yann.morin.1998@free.fr> 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>

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>
