Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP} if not already defined. This allows building libc from outside of lib/libc using a reach-over makefile. A typical use-case is to build a standard ILP32 version and a COMPAT32 version in a single iteration by building the COMPAT32 version using a reach-over makefile.

Turn libc.so into an ld script rather than a symlink pointing to the real shared object and libssp_nonshared.a. This was the last showstopper that prevented from enabling SSP for ports by default. portmgr@ performed a buildworld which showed no significant breakage with this patch. Details: On i386 for PIC objects, gcc uses the __stack_chk_fail_local hidden symbol instead of calling __stack_chk_fail directly [1]. This happen not only with our gcc-4.2.1 but also with the latest gcc-4.8. If you want the very nasty details, see [2]. OTOH the problem doesn't exist on other architectures. It also doesn't exist with Clang as the latter will somehow manage to create the function in the object file at compile time (contrary to only referencing it through a symbol that will be brought in at link time). In a perfect world, when an object file is compiled with -fstack-protector, it will be linked into a binary or a DSO with this same flag as well, so GCC will add libssp_nonshared.a to the linker command-line. Unfortunately, we don't control softwares in ports and we may have such broken DSO. This is the whole point of this patch. You can reproduce the problem on i386 by compiling a source file into an object file with "-fstack-protector-all -fPIE" and linking it into a binary without "-fstack-protector". This ld script automatically proposes libssp_nonshared.a along with the real libc DSO to the linker. It is important to understand that the object file contained in this library will be pulled in the resulting binary _only if_ the linker notices one of its symbols is needed (i.e. one of the SSP symbol is missing). A theorical performance impact could be when compiling, but my testing showed less than 0.1% of difference. [1] For 32-bit code gcc saves the PIC register setup by using __stack_chk_fail_local hidden function instead of calling __stack_chk_fail directly. See comment line 19460 in: src/contrib/gcc/config/i386/i386.c [2] When compiling a source file to an object file, if you use something which is external to the compilation unit, GCC doesn't know yet if this symbol will be inside or outside the DSO. So it expects the worst case and routes the symbol through the GOT, which means additional space and extra relocation for rtld(1). Declaring a symbol has hidden tells GCC to use the optimal route (no GOT), but on the other hand this means the symbol has to be provided in the same DSO (namely libssp_nonshared.a). On i386, GCC actually uses an hidden symbol for SSP in PIC objects to save PIC register setup, as said in [1]. PR: ports/138228 PR: ports/168010 Reviewed by: kib, kan

- Reenable Native Language Support in libc. This feature was disabled due to possible breakages in the catalog handling code. Since then, that code has been replaced by the secure code from NetBSD but NLS in libc remained turned off. Tests have shown that the feature is stable and working so we can now turn it on again. - Add several new catalog files: - ca_ES.ISO8859-1 - de_DE.ISO8859-1 - el_GR.ISO8859-7 (by manolis@ and keramida@) - es_ES.ISO8859-1 (kern/123179, by carvay@) - fi_FI.ISO8859-1 - fr_FR.ISO8859-1 (kern/78756, by thierry@) - hu_HU.ISO8859-2 (by gabor@) - it_IT.ISO8859-15 - nl_NL.ISO8859-1 (corrections by rene@) - no_NO.ISO8859-1 - mn_MN.UTF-8 (by ganbold@) - sk_SK.ISO8859-2 - sv_SE.ISO8859-1 (The catalogs without explicit source has been obtained from NetBSD.)

Add the BSD-licensed Citrus iconv to the base system with default off setting. It can be built by setting the WITH_ICONV knob. While this knob is unset, the library part, the binaries, the header file and the metadata files will not be built or installed so it makes no impact on the system if left turned off. This work is based on the iconv implementation in NetBSD but a great number of improvements and feature additions have been included: - Some utilities have been added. There is a conversion table generator, which can compare conversion tables to reference data generated by GNU libiconv. This helps ensuring conversion compatibility. - UTF-16 surrogate support and some endianness issues have been fixed. - The rather chaotic Makefiles to build metadata have been refactored and cleaned up, now it is easy to read and it is also easier to add support for new encodings. - A bunch of new encodings and encoding aliases have been added. - Support for 1->2, 1->3 and 1->4 mappings, which is needed for transliterating with flying accents as GNU does, like "u. - Lots of warnings have been fixed, the major part of the code is now WARNS=6 clean. - New section 1 and section 5 manual pages have been added. - Some GNU-specific calls have been implemented: iconvlist(), iconvctl(), iconv_canonicalize(), iconv_open_into() - Support for GNU's //IGNORE suffix has been added. - The "-" argument for stdin is now recognized in iconv(1) as per POSIX. - The Big5 conversion module has been fixed. - The iconv.h header files is supposed to be compatible with the GNU version, i.e. sources should build with base iconv.h and GNU libiconv.

Add a new ARM TARGET_ARCH, armv6hf. This is considered experimental. This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit. This is an optional coprocessors may not be present in all devices, however it appears to be in all current SoCs we support. armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too old to support this. Because of this there are a number of WITH/WITHOUT options that are unsupported and must be left as the default value. The options and their required value are: * WITH_ARM_EABI * WITHOUT_GCC * WITHOUT_GNUCXX In addition, without an external toolchain, the following need to be left as their default: * WITH_CLANG * WITH_CLANG_IS_CC As there is a different method of passing float and double values to functions the ABI is incompatible with existing armv6 binaries. To use this a full rebuild of world is required. Because no floating point values are passed into the kernel an armv6 kernel with VFP enabled will work with an armv6hf userland and vice versa.

.if ${MK_FP_LIBC} == "no"
Add option NO_FP_LIBC, which disables floating-point support in *printf() and *scanf(). Currently, this reduces the size of libc.so by 9K on i386. But the real savings are for static binaries that use *printf() or *scanf() but not strtod(); with an FP-disabled libc, these binaries will not depend on the gdtoa routines, making each binary about 22K smaller.

Disable RPC exponential back-off for FreeBSD.org systems (IE. hidden behind _FREEFALL_CONFIG). This is done mainly to make NIS even more resistant to packet loss. This is not enabled by default for "normal" FreeBSD since it might cause the server providing the RPC service to be hit heavily with RPC traffic in case of problems. freefall.FreeBSD.org and hub.FreeBSD.org have been running with a patch similar to this for a couple of weeks.

Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP} if not already defined. This allows building libc from outside of lib/libc using a reach-over makefile. A typical use-case is to build a standard ILP32 version and a COMPAT32 version in a single iteration by building the COMPAT32 version using a reach-over makefile.

Merge index() and strchr() together. As I looked through the C library, I noticed the FreeBSD MIPS port has a hand-written version of index(). This is nice, if it weren't for the fact that most applications call strchr() instead. Also, on the other architectures index() and strchr() are identical, meaning we have two identical pieces of code in the C library and statically linked applications. Solve this by naming the actual file strchr.[cS] and let it use __strong_reference()/STRONG_ALIAS() to provide the index() routine. Do the same for rindex()/strrchr(). This seems to make the C libraries and static binaries slightly smaller, but this reduction in size seems negligible.

Fix known issues which blow up the process after dlopen("libthr.so") (or loading a dso linked to libthr.so into process which was not linked against threading library). - Remove libthr interposers of the libc functions, including __error(). Instead, functions calls are indirected through the interposing table, similar to how pthread stubs in libc are already done. Libc by default points either to syscall trampolines or to existing libc implementations. On libthr load, libthr rewrites the pointers to the cancellable implementations already in libthr. The interposition table is separate from pthreads stubs indirection table to not pull pthreads stubs into static binaries. - Postpone the malloc(3) internal mutexes initialization until libthr is loaded. This avoids recursion between calloc(3) and static pthread_mutex_t initialization. - Reinstall signal handlers with wrapper on libthr load. The _rtld_is_dlopened(3) is used to avoid useless calls to sigaction(2) when libthr is statically referenced from the main binary. In the process, fix openat(2), swapcontext(2) and setcontext(2) interposing. The libc symbols were exported at different versions than libthr interposers. Export both libc and libthr versions from libc now, with default set to the higher version from libthr. Remove unused and disconnected swapcontext(3) userspace implementation from libc/gen.

Add reachover Makefiles for contrib/netbsd-tests/lib/libc; this adds approximately 500 new testcases Various TODOs have been sprinkled around the Makefiles for items that even need to be ported (missing features), testcases have issues with building/linking, or issues at runtime. A variant of this code has been tested extensively on amd64 and i386 10-STABLE/11-CURRENT for several months without issue. It builds on other architectures, but the code will remain off until I have prove it works on virtual hardware or real hardware on other architectures In collaboration with: pho, Casey Peel <casey.peel@isilon.com> Sponsored by: EMC / Isilon Storage Division

Replaced an ugly hack to selectively disable warnings in contributed sources with just a hack made possible by bsd.sys.mk,v 1.33. This is better because it just nulls out the warning flags rather than adding gcc(1) specific -w option to CFLAGS.

# Disable warnings in contributed sources.
Disable all warnings when building gdtoa. This allows building libc with clang. The general idea is that the vendor will not accept our compilation patches and so disabling the warnings is the best way to go as it makes future imports bearable.

Enable GCC stack protection (aka Propolice) for userland: - It is opt-out for now so as to give it maximum testing, but it may be turned opt-in for stable branches depending on the consensus. You can turn it off with WITHOUT_SSP. - WITHOUT_SSP was previously used to disable the build of GNU libssp. It is harmless to steal the knob as SSP symbols have been provided by libc for a long time, GNU libssp should not have been much used. - SSP is disabled in a few corners such as system bootstrap programs (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves. - It should be safe to use -fstack-protector-all to build world, however libc will be automatically downgraded to -fstack-protector because it breaks rtld otherwise. - This option is unavailable on ia64. Enable GCC stack protection (aka Propolice) for kernel: - It is opt-out for now so as to give it maximum testing. - Do not compile your kernel with -fstack-protector-all, it won't work.
