Sat, 17 Jan 2026 07:41:56 +0100

libc: drop NO_FP_LIBC supportNO_FP_LIBC was added in 2004 to save space by disabling FP support in*printf()/*scanf(). The size benefit is negligible on modern systemsand conflicts with assumptions made by current base utilities.Remove the option and always build libc with floating-point support.Reported by: Oskar Holmlund MFC after: 2 weeks List of files: /freebsd/lib/libc/Makefile

libc/resolv: get rid of MD5MD5 is used by libc/resolv to generate a random sequence id from acurrent time stamp. Replace this convoluted mechanism with a callto arc4random().

libmd, kern, stand: consolidate md5 implementations (NFC)Reduce the number of md5c.c between the three of these from two to oneby just reaching into the kernel build for both userland builds. Theprecedent for this already exists for sha2 in both cases._libmd_ symbol privatization bits have been moved to sys/md5.h andmd5.h remains to #include for compatibility.This stops exporting MD5Pad() in the process because the kernel stoppedexporting it in 502a35d60f4c. soversion is bumped accordingly.This also renames the libc version of stack_protector.c; it previouslyonly worked by coincidence because .PATH ordering worked out such thatwe got the right one, but this is not the case anymore.

lib{c,sys}: return wrapped syscall APIs to libcThese provide standard APIs, but are implemented using another systemcall (e.g., pipe implemented in terms of pipe2) or are interposed by thethreading library to support cancelation.After discussion with kib (see D44111), I've concluded that it isbetter to keep most public interfaces in libc with as littleas possible in libsys.Reviewed by: kibDifferential Revision: https://reviews.freebsd.org/D44241 List of files: /freebsd/lib/libc/Makefile

libc: link libsys as a auxiliary filter libraryAt runtime, when rtld loads libc it will also load libsys. For eachsymbol that is present in both, the libsys one will override the libcone. It continues to be the case that program need only link againstlibc (usually implicitly).

lib{c,lzma,z}: remove -DSYMBOL_VERSIONING from CFLAGSThis was part of a libkse and libpthread transition aide when libcgained symbol versions in e62165c8b0f7d6452c0033127a0fd8ad1d9e34d3(March 2006). The code that cared about this macro was removed incommit 00fb440c1a145b56b6c75fd405d80071aef2aab1 (May 2007) when symbolversioning was enabled by default and libthr became the defaultthreading library. For unknown reasons, it stayed in libc (whichseemingly never used it) and seems to have been copied to liblzma andlibz.Reviewed by: imp, kib, emasteDifferential Revision: https://reviews.freebsd.org/D42613 List of files: /freebsd/lib/libc/Makefile
