| * Makefile.flags: use all cflags for crypt and rt checksMartin Kaiser2021-12-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To check if libcrypt and librt are available, we check if we can compile and link a simple test program. These checks do not match the actual linking if CONFIG_STATIC is enabled. For CONFIG_STATIC, CFLAGS_busybox is set to -static. The checks don't use CFLAGS_busybox and detect a shared libcrypt or librt. If we link busybox later and we have no static libcrypt or librt, linking will fail. Update the libcrypt and librt checks to use CFLAGS_busybox. Signed-off-by: Martin Kaiser <martin@kaiser.cx> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* | win32: add local dirent implementationRon Yorston2021-06-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Add a cut down version of the dirent implementation from git. The git developers said: The mingw-runtime implemenation of opendir, readdir and closedir sets errno to 0 on success, something that POSIX explicitly forbids. This also avoids having to link against libssp.a (commit 13eb34205) and reduces the size of the binary by 2KB.

| * Makefile.flags: fix the OS detection for libresolvMartin Kaiser2021-02-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 054493350 ("Do not add -lresolv on non-Linux systems") adds a condition to link with libresolv only on linux systems. The check requires that CONFIG_UNAME_OSNAME equals Linux. This works only if the uname applet is enabled. Otherwise, CONFIG_UNAME_OSNAME is empty, regardless of the platform. By default, CONFIG_UNAME_OSNAME is the output of uname -o. For most linux systems, uname -o returns "GNU/Linux" and the check fails. In this case, linking a static busybox fails because of missing symbols from libresolv. networking/lib.a(nslookup.o): In function `add_query': nslookup.c:789: undefined reference to `__res_mkquery' networking/lib.a(nslookup.o): In function `parse_reply': nslookup.c:355: undefined reference to `ns_initparse' nslookup.c:361: undefined reference to `ns_parserr' nslookup.c:404: undefined reference to `ns_name_uncompress' nslookup.c:418: undefined reference to `ns_get16' nslookup.c:419: undefined reference to `ns_name_uncompress' .. nslookup.c:456: undefined reference to `ns_get16' ... nslookup.c:469: undefined reference to `ns_name_uncompress' ... nslookup.c:489: undefined reference to `ns_get32' ... collect2: error: ld returned 1 exit status This patch uses the output of $CC -dumpmachine to detect the target platform for which we compile. Both gcc and clang support -dumpmachine. Like the original patch, we link against libresolv only if our target platform is linux-based.

* | build system: use static ssp libraryRon Yorston2020-11-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The previous commit got rid of a link error but generates a binary that isn't standalone: it requires libssp-0.dll. Force the use of the static ssp library. This also requires mingwex to be added to LDLIBS, since that's what has a dependency on ssp. Other workarounds are to compile with non-zero _FORTIFY_SOURCE (which increases the size of the binary) or to add '-u ___strcpy_chk' to LDFLAGS (likely to be fragile).

* | win32: use lazy loading for certain DLLsRon Yorston2020-06-021-1/+1
| | | | | | | | | | | | | | | | | | Only a handful of functions are used from shell32.dll, userenv.dll and psapi.dll. Mostly these functions are in out of the way places. By loading the functions only when required we can avoid the startup cost of linking the three DLLs in the common case that they aren't needed.

| * build system: remove KBUILD_STR()Jean-Philippe Brucker2020-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using GNU Make >=4.3, the KBUILD_STR() definition interferes badly with dependency checks during build, and forces a complete rebuild every time Make runs. In if_changed_rule, Kconfig checks if the command used to build a file has changed since last execution. The previous command is stored in the generated .<file>.o.cmd file. For example applets/.applets.o.cmd defines a "cmd_applets/applets.o" variable: cmd_applets/applets.o := gcc ... -D"KBUILD_STR(s)=#s" ... Here the '#' should be escaped with a backslash, otherwise GNU Make interprets it as starting a comment, and ignore the rest of the variable. As a result of this truncation, the previous command doesn't equal the new command and Make rebuilds each target. The problem started to appear when GNU Make 4.3 (released January 2020), introduced a backward-incompatible fix to macros containing a '#'. While the above use of '#', a simple Make variable, still needs to be escaped, a '#' within a function invocation doesn't need to be escaped anymore. As Martin Dorey explained on the GNU Make discussion [1], the above declaration is generated from make-cmd, defined as: make-cmd = $(subst \#,\\\#,$(subst $$,$$$$,$(call escsq,$(cmd_$(1)))) Since GNU Make 4.3, the first argument of subst should not have a backslash. make-cmd now looks for literally \# and doesn't find it, and as a result doesn't add the backslash when generating .o.cmd files. [1] http://savannah.gnu.org/bugs/?20513 We could fix it by changing make-cmd to "$(subst #,\#,...)", but to avoid compatibility headaches, simply get rid of the KBUILD_STR definition, as done in Linux by b42841b7bb62 ("kbuild: Get rid of KBUILD_STR"). Quote the string arguments directly rather than asking the preprocessor to quote them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From Rich Felker: By default, modern GCC generates DWARF2 debug/unwind tables in the .eh_frame section of the object files/binaries. This adds significant bloat (as much as 15%) to the size of the busybox binary, including the portion mapped/loaded into memory at runtime (possibly a big issue for NOMMU targets), and the section is not strippable with the strip command due to being part of the loaded program text. I've since done some further checking - both testing and asking the GCC developers about it - and it seems the solution is to add to the CFLAGS -fno-unwind-tables and -fno-asynchronous-unwind-tables. If debugging is disabled, this will prevent GCC from outputting DWARF2 tables entirely. But since busybox builds with -g by default, the interesting case is what happens then. I originally thought these options would break debugging, but they don't; instead, they tell GCC to output the DWARF2 tables in the .debug_frame section instead of the newish .eh_frame section (used for exception handling). With these options added, busybox_unstripped is still fully debuggable, and the final busybox binary loses the 15% bloat factor from the DWARF2 tables.

| * disable format security warningsMike Frysinger2012-08-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We pass strings to printf directly a lot. Some distros enable some flags in their gcc by default like -Wformat-security. With these two things, we end up with a lot of build warnings like so: loginutils/chpasswd.c:42:3: warning: format not a string literal and no format arguments [-Wformat-security] But we don't care. Our focus is first and foremost on size, so adding a lot of dummy calls like: - printf(some_constant_string); + printf("%s", some_constant_string); is pointless bloat. Disable this warning flag if the compiler supports it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
