3 This has been a long time in the making... Release highlights:
4 o New stdio implementation
5 o New optimized string functions
6 o Major improvements to the shared lib loader
7 o Shared libraries work properly on powerpc
8 o Debugging works on mips
9 o New architectures: frv, nios, nios2, bfin
10 o Linux 2.6.x kernel support
11 o Lots and lots of bug fixes
13 This release is NOT binary compatible with uClibc 0.9.26 or any earlier
14 release, so be prepared to recompile your software if you are still using
15 an old version of uClibc.
23 This simply adds a fix for a pthread bug that was noticed a few hours
24 after the previous release. Otherwise identical to 0.9.25.
26 This release remains binary compatible with uClibc 0.9.21-25 as long as
27 you take care to avoid any configuraton changes that will break things.
28 We _were_ planning to break binary compatibilty in this release, but
29 decided to hold those changes so we could push out a bugfix release.
31 We _will_ break binary compatibilty in the upcoming 0.9.27 release to
32 implement a few things we have been postponing. That should hopefully be
33 the last ABI change before we freeze the ABI for the upcoming 1.0.x
37 o A trivial fix for a pthread bug
46 See Changelog.full for the complete list of who did what.
49 This release remains binary compatible with uClibc 0.9.21-24 as long as
50 you take care to avoid any configuraton changes that will break things.
51 We _were_ planning to break binary compatibilty in this release, but
52 decided to hold those changes so we could push out a bugfix release.
54 We _will_ break binary compatibilty in the upcoming 0.9.26 release to
55 implement a few things we have been postponing. That should hopefully be
56 the last ABI change before we freeze the ABI for the upcoming 1.0.x
60 o Fixed a ton of problems found using the LTP and NIST test suites.
61 The few remaining test failures are obscure corner cases, such as
62 a few functions that fail (correctly) with incorrect errno values.
63 o Fixed a longstanding pthreads bug -- amoung other things, you no
64 longer need to explicitly add -lpthread for perl to work.
65 o Added some sh optimized string functions
66 o Added sh64 shared library support
67 o The default malloc implementation has been replaced, and will
68 now actually free memory when told to do so.
69 o Both popen() and exec*() now behave themselves per SuSv3
70 o Better 2.6.x kernel header support
71 o Added support for Position Independent Executables (PIE) on x86
72 o Lots of other minor cleanups
78 0.9.24 15 December 2003
80 See Changelog.full for the complete list of who did what.
83 This release remains binary compatible with uClibc 0.9.21-23 as
84 long as you take care to avoid any configuraton changes that will
87 We currently plan to break binary compatibilty in the upcoming 0.9.25 to
88 implement a few things we have been postponing, which will hopefully be
92 o Fixed several silly configuration problems
93 o Added arm optimized string functions
94 o Lots of minor cleanups
102 0.9.23 13 November 2003
104 See Changelog.full for the complete list of who did what.
107 This release is binary compatible with uClibc 0.9.21 and 0.9.22 as
108 long as you take care to avoid any configuraton changes that will
109 break things. Enabling or disabling things like soft-float,
110 locale, wide wchar support, or changing cpu type are all good
111 examples of things that will break binary compatibility.
114 o Fixed several silly configuration problems that were
115 present in the 0.9.22 release.
116 o Fixed compilation problem with soft-float support on
117 several architectures.
118 o Lots of cleanup work on the powepc shared lib loader
119 thanks to Joakim Tjernlund.
120 o Updated the debian packaging for use in a standalone uClibc
121 system, rather than being a subordinate library under a
130 0.9.22 8 November 2003
132 See Changelog.full for the complete list of who did what.
135 This release is binary compatible with the 0.9.21 release
136 if you take care to avoid any configuraton changes that
137 might break things for you (i.e. enabling or disabling things
138 like soft-float, locale, wide wchar support, or changing cpu
139 type are all good examples of binary incompatible config options).
142 o Added e1, microblaze, and sh64 architectures.
143 o Much improved soft-float support
144 o Rewrote the passwd and group handing functions
145 and implemented all SuSv3 required reentrant
147 o Reworked and updated the Config system. You now
148 get to select your target architecture with the
150 o Fixed pthreads for mmuless m68k systems
151 o Added some x86 optimized string functions.
152 o Lots and lots of bugs fixed.
160 0.9.21 9 September 2003
162 See Changelog.full for the complete list of who did what.
165 This release is not binary compatible with earlier releases.
166 Sorry about that. We have never promised to provide binary
167 compatibility until we hit version 1.0, and even then, if
168 you change your configuration.
171 o uClibc now has full ANSI/ISO C99 locale support (except
172 for wcsftime() and collating items in regex).
173 o Added support for using pre-generated locale data, making
174 it easy for mere mortals to use uClibc w/locale support.
175 o Lots of new tuning options added to trade size
176 for features, allowing for smaller static binaries.
177 o The "dlopen()'ing libraries that depend on libraries"
179 o A new scanf implementation. Well tested, but
180 brand new so watch for obscure bugs...
181 o Reworked and updated the Config system, adding several
182 nice new features which we now use.
183 o Lots and lots of sundry bug fixes and cleanups.
193 See Changelog.full for the complete list of who did what.
196 This release remains binary compatible with 0.9.18 and 0.9.19.
200 o Some ldd, profiling, and gcc wrapper updates
201 o Updated to support and compile with gcc 3.3
202 o Several needed mips updates
203 o Building under cygwin should now work...
204 o Prevent non-PIC code getting into PIC libs
205 o Added mmap64 support
206 o mmu-less systems now get a 16k default thread stack size
207 which is much more sane than the old 2 MB default...
208 o Implemented syscall() for powerpc
209 o Optionally struct tm extension support
210 o Lots of other sundry little fixes and cleanups.
211 o Prevent buffer overflows in the passwd and group functions.
221 See Changelog.full for the complete list of who did what.
224 This release remains binary compatible with 0.9.18 (except
225 for mips, but then mips was unusable in stock 0.9.18 anyways).
230 o Some Makefile and warning fixes
232 o Fixed gcc wrapper handling of ctor/dtor stuff when used in
233 with and w/o the nostdinc and nostdlib options
235 o Fixed a number of system call kernel type/user type translation
236 problems that scrambled a handful of system calls.
237 o Fixup powerpc syscalls to eliminate warnings with gcc-3.2
238 o Fixed several ioctl special cases for powerpc
239 o Checked in forgotten mips kernel_types.h changes
240 o Fixed mips shared library loader bug that caused segfaults
241 o Major update to the pthreads library. Should improve performance.
242 o Fixed uClibc's shared library loader so we can properly debug
243 applications using pthreads (must use gdb 5.3 or newer which
244 was compiled using uClibc).
245 o Made uClibc's ldd act just the glibc provided one (i.e. relying
246 on the shared lib loader to do the work) when it is possible to
247 doi so, and only rummage about the ELF headers when we have no
248 other choice (such as when using 'ldd' on cross compiled stuff).
250 o header file updates for v850 architecture
251 o Fixed v850 crt0.S __uClibc_main argument stack space
253 o Fixed res_init() so it properly reloads /etc/resolv.conf
255 o Fixed ARM setjmp when floating point was disabled
257 o Removed debug (-g) when building crti.o and crtn.o, as
258 debug would mess up the build for SH4 and probably others.
259 o Fixed SH setjmp when floating point was enabled
268 0.9.18 12 February 2003
270 See Changelog.full for the complete list of who did what.
274 Once again, this release is _NOT_ binary compatible with earlier
275 releases. I _think this will be the last time (with the possible
276 exception of some future changes to our locale support...)
281 o fixed a compile problem when large file support was disabled
282 o fixed dlib_pic.o to compile with proper flags
283 o fixed a shared lib loader compile warning
284 o Made adding libgcc functions to uClibc optional
286 o Fixed scandir64 to not free the wrong pieces of memory
287 which caused segfaults
288 o Fixed mismatches between kernel and libc dirent structures
289 o Fixed mismatches between the size of uClibc's struct dirent
290 and struct dirent64 so that when _FILE_OFFSET_BITS=64 we
291 do not lose part of the filename
292 o Fixed getdents64.c so the build will not break when compiling
293 vs a 2.0.x Linux kernel when UCLIBC_HAS_LFS is enabled
294 o Create stub crti.o and crtn.o files when UCLIBC_CTOR_DTOR is disabled
295 o Fixed licenses for a few files that erroneously were listed as GPL
296 but were really LGPL after discussing with authors
297 o sigaction for x86 had an extra and unwanted sigaction syscall
298 o Fixed debugging of arm binaries by adding a .note.ABI-tag section
300 o header file updates for v850 architecture
301 o Fixed v850 clone syscall
303 o Fixed pthread_cond_timedwait to properly uses rt singals
306 o Added mips _flush_cache syscall
308 o Added m68k brk syscall
310 o Fixed pipe implementation for mips
319 0.9.17 25 January 2003
321 See Changelog.full for the complete list of who did what.
325 I have always reserved the right to make binary incompatible changes as
326 needed prior to the "1.0" release. This release is a good example of
327 that. A few bugs turned up that needed to be fixed and the only good way
328 to fix them was to change some fundamental data structure sizes. So I did
329 just that. As a result, this release is _NOT_ binary compatible with
330 earlier releases -- you will need to recompile your applications.
335 o fixed a number of shared library loader bugs
336 o setjmp, longjmp, clone, and vfork cleanups for the SH architecture
337 o Don't build the config system with ncurses unless asked to
339 o cris architecture updates
341 o Changed 'struct stat' and 'struct stat64' so they use types that
342 are consistant with use elsewhere in the library. Without this,
343 subtle bugs would occur due to comparing signed and unsigned
344 types (for example, GNU tar wouldn't work)
345 o Fixed dlopen so it works with staticly linked apps
346 o Fixed sigaction on arm architecture so sa_restorer works properly
347 o Fixed sigaction on x86 architecture for (fixed debugging threads)
348 o Fixed a wide char related segfault in the regular expression code
349 o Powerpc pread and pwrite are now implemented correctly
350 o Powerpc syscall mechanism re-implemented
351 o Sparc architecture and syscall mechanism fixed up so things compile
352 o usershell reimplemented
353 o Fixed global destructors for staticly linked applications
354 o Added dynamic atexit support (needed for full C++ ctor/dtor support)
355 o The ldd utility now acts more like the GNU utility
356 o Added a stub libnsl library to make stupid configure scripts bahave
357 o Always build crt1.o as well as crt0.o to minimize the need to mess
359 o Rewrote powerpc crt0.S to properly handle ctors/dtors
360 o Removed unimplemented and legacy stuff from our header files to
361 make configure behave better
362 o Made the lib loader also support libs in /usr/X11R6/lib by default
363 o Config system updates
364 o networking function updates
365 o Large file support updates
366 o Lots of other little bug fixes and cleanups
370 o Fixed pthread_mutex_lock and pthread_mutex_unlock so they
371 actually work as advertised on mips
372 o Fixed several nasty pthread bugs fixing debugging
374 o Fixed potential segfaults during 'make menuconfig'
376 o Fixed a subtle problem in the DNS resolver that prevented
377 uncompressed DNS lookup responses from working
379 o Fixed pclose error handling
381 o fixed the problem where arm binaries would crash on start
382 that Erik stupidly caused right before the last release.
384 o Major locale support update!
385 o Allow people to use pregenerated locale data instead of generating
386 approx 40Mb of glibc locales to get the 300+ locales currently
388 o locale dependent collation support
389 o Fixed locale support tools to work when cross-compiling
390 o Added the *wprintf functions
391 o Added the wcsto{inttype} functions
392 o Added iconv() and a mini iconv utility
393 o Added hsearch and hsearch_r
394 o Fixed a silly bug allowing wprintf %s to work correctly.
395 o Fixed fdopen when used with "a" (append).
396 o Fixed stdio file position handing to be sure fell() always
397 gives correct results
399 o Fixed a buffer overflow in getlogin_r
401 o Hitachi h8300 architecture update
403 o Powerpc shared library relocation fixes
409 0.9.16 8 November 2002
411 See Changelog.full for the complete list of who did what.
414 o CRIS architecture and shared library support from Tobias Anderberg
415 o New uClibc configuration system
416 o shared library global constructors and destructors initialization
417 ordering fixed by Stefan Allius
418 o More SuperH architecture fixes from Stefan Allius
419 o uClibc now compiles with newer versions of gcc (i.e. RedHat 8.0)
420 o uClibc no longer requires perl to compile
421 o mips dlopen was fixed by Steven J. Hill
422 o pty and tty handling fixes
423 o Manuel Novoa added support for a new /etc/TZ file for globally
424 setting the system timezone.
425 o Manuel also fixed up a number of remaining wide char issues.
426 o Lots of other little bug fixes and cleanups
432 0.9.15 27 August 2002
434 This is a minor bugfix release.
436 See Changelog.full for the complete list of who did what.
438 o Eliminated the HAS_LONG_LONG option. gcc always supports
439 long long, and the option never excluded all long long anyways.
440 o ctype.h no longer allows multiple argument evaluation in
441 compliance with ANSI/ISO C99
442 o Obscure printf fixes -- one involving %o and one involving %f.
443 o Bugfixes for locking and reentrance in password/group functions
444 o Directly use kernel types for most items, eliminating needless
445 translation and fixing several bugs.
446 o Directly use kernel struct stat -- no more translating
447 o More superH (sh) architecture merging from Stefan Allius
448 o Errno values and strerror are now correct on alpha, sparc, and mips
449 o Fixed an obscure bug with fclose when custom streams are enabled.
450 o Lots of other little bug fixes and cleanups
456 0.9.14 12 August 2002
458 This is a minor bugfix release.
460 See Changelog.full for the complete list of who did what.
462 o Fix a compile error when RPC and Pthread support
464 o Eliminate duplicate define warnings in wstring.c.
465 o Fix potentially broken preprocessor comparisons.
466 o Erik was an idiot and broke thread locking in exit(),
467 atexit() and friends. Fix that.
468 o Fix the gcc wrapper to use crtbeginS.o and crtendS.o when
469 compiling PIC code (crtbegin.o and crtend.o) otherwise.
479 o There was an off-by-one buffer overflow in the group
480 handling code, fix thanks to Joseph Chiu.
481 o There was an integer overflow bug in calloc, per
482 http://online.securityfocus.com/bid/5398
483 o There was an integer overflow bug in the xdr_array
484 RPC code, per http://online.securityfocus.com/bid/5356
486 See Changelog.full for the complete list of who did what.
488 o Add full shared library support for Hitachi SuperH (sh)
489 thanks to Stefan Allius and Edie C. Dost
490 o Lots of reentrance cleanups (we should now be fully
491 reentrant when compiled with pthread support).
492 o Miles Bader implemented a new mmap based malloc which is much
493 smarter than the old "malloc-simple", and actually works, unlike
494 the old "malloc". This is now the default for mmu-less systems
495 and should greatly help reduce memory fragmentation and wastage.
496 o Reworked syscall handling for i386 and ARM, smaller and cleaner.
497 o Support for the syscall() function on i386 and ARM
498 o The uClibc g++ wrapper now automagically adds the proper include
499 search path and and libraries.
500 o Lots of shared library loader updates
501 o dlopen'd shred libraries not properly run destructors
502 when ctor/dtor support is enabled
503 o pread/pwrite/pread64/pwrite64 now all work as expected
504 o Lots and lots of other bug fixes and cleanups.
513 See Changelog.full for the complete list of who did what.
515 o Add full shared library support for mips (big and little
516 endian), thanks to a lot of hard work from Steven J. Hill
517 o i960 architecture support, thanks to Martin Proulx
518 o An initial alpha port (works, but needs some cleanup)
519 o Fixes shared library support for powerpc
520 o Fixes for mmu-less systems
521 o Much improved thread locking and reentrance.
522 o More gcc wrapper updates. XFree86 really does link
523 this time around. It still didn't last time.
524 o Libcrypt now passes conformance tests
525 o Nearly complete locale supporti thanks to a lot
526 of hard work by Manuel Novoa III. This stuff is
527 _way_ smaller than glibc's
528 o Completely new time handling functions also by Manuel
529 o Lots of other bug fixes and cleanups.
541 o Much better large file support
542 o Several gcc wrapper bug fixes, so things like iproute2 and
543 XFree86 should now link properly.
544 o Fixes a stdio thread locking bug that could cause random
545 deadlocks on s*printf calls when threading was enabled.
548 o Added a generic implementation of truncate64.c and ftruncate64.c

550 o Removed internal erroneous use of __USE_FILE_OFFSET64
551 o Made libpthread compile on sparc and powerpc
552 o Made libpthread soname and symlinks match the other libraries.
553 o Added finite() to the C89 math lib, since some math functions use it.
554 o Added missing function pointer to error.c (some apps wanted it)
555 o Fixed initfini build for arches where gcc tries to be sneaky
556 o Fixed m68k/bits/setjmp.h which I has broken in the last release.
557 o Fixed a buffer overflow in the dynamic library loader
558 o Fixed a stdio thread locking bug that could cause random
559 deadlocks on s*printf calls when threading was enabled.
560 o Implemented sqrtf(), needed for libstdc++ on arm
562 o Make clean fixes to not blindly wipe all symlinks
563 o Re-enabled clnt_perror()
564 o Re-implemented swab()
566 o Many updates to the uClibc Working Application List
568 o Many updates to the mips dynamic loader. Not yet working but
569 getting very close now.
570 o Fixed locking bug in getttyent()
571 o Support libpthread on mips
573 o Fixed several bugs in utmp code (pututline was only writing the
574 first sizeof-a-pointer bytes to the utmpfile).
575 o setutent() was only opening utmp readonly.
577 o Fixed a silly typing problem with the getuid syscall.
579 o Fixed stdio FILE read/write auto-transition bugs.
580 o Better stdio errno handling
581 o Changed setvbuf() to more closely match glibc's behavior
582 o Fixed getpass() to not echo passwords to the console
583 o Fixed locale ISblank flag.

589 o Fixed h8300 architecture support for pthreads and changes to
592 o Made powerpc assembly code PIC-compatible
593 o Removed powerpc R_PPC_REL24 handling, since it was deceptively useless.
595 o Several types on powerpc, such as dev_t, are different than on other
596 architectures. John spotted this, which fixed a _ton_ of problems since
597 anything calling stat() was previously broken.
599 o Eliminated use of alarm() from the DNS resolver by converting
600 it to use select instead (much cleaner).
612 o pthreads support (derived from glibc 2.1.3's linuxthreads library)
613 by Stefan Soucek and Erik Andersen
614 o pthreads support for MMU-less systems, by Stefan Soucek
615 o Complete rewrite of all stdio functions for standards compliance,
616 small size, pthreads support, wide/narrow stream support, large
617 file support, unbuffered support, etc, etc by Manuel Novoa III
618 o gcc wrapper reworked by Erik Andersen. Now operated correctly in
619 all known cases, and now wraps g++ as well for C++ support.
620 o constructor/destructor support, for C++ by Erik Andersen.
621 o Eliminated duplicate include/bits header files, by Erik Andersen.
622 Now all common include/bits headers are grouped together.

638 o Fix ldso build for older arm cross compilers
641 o fixed gcc wrapper handling of -M* options
642 o Fixed truncate64/ftruncate64 to restrict them to 64-bit systems,
643 since we can't be sure that the _syscall macros can cope with 64
644 bit args on 32 bit arches.
645 o Large File support on the v850
646 o Fixed v850 headers after Erik messed them up
647 o Eliminate include/features.h namespace pollution
649 o Fixed pthread support for SH, and fixed SH vfork as well
650 o Fixed SH headers after Erik messed them up

667 pthreads support, wide/narrow stream support, large file support,
668 unbuffered support, etc, etc, etc.
669 o Rewrote the various string to int functions to be smaller, more
670 standards compilant, and reduce dependance on libgcc.a.

693 o A bunch of doc updates. Major update to the working
695 o Added a configurator script (extra/Configs/uClibc_config_fix.pl)
696 which can simplify configuring uClibc.
697 o Fixed setjmp/longjmp on x86,arm,powerpc,mips,and sparc.
698 Hitting ^C in ash kills client apps now, not ash.
699 o Reworked signal handling code so it now passes POSIX
701 o Fixed sleep and usleep to work correctly when
702 interrupted by signals.
703 o Made getopt behave the same when staticly linking
704 as when dynamicly linking. It was using different
705 implementations depending on how apps were linked.

707 o Eliminate all C++ style comments from header files
708 o Support statvfs and statfs
709 o Support getmntent_r

716 o Allow regex to be excluded at compile time
717 o Implemented mempcpy
718 o Build ldd and readelf for the target system and for the
720 o Fix several cases where get-needed-libgcc-objects.sh
721 could fail, breaking the shared uClibc library.
722 o Include all shared library loader objects into a
723 single C file, thereby reducing its size further.
724 o Reworked the shared library linking process to be more
725 flexible so that gcc and ld can more easily be built to
726 target uClibc library.
727 o Better error checking in the Makefiles. Be more pedantic
728 about tar, chmod, etc to avoid system dependent failures.
729 o We can now autodetect the target architecture
730 o Hide references to wchar_t so GNU autoconf
731 configure scripts won't get confused and try to
732 enable wide char support.
733 o Fixed stdio.h so apps can use varargs.h if they want to.
734 o Added brk/sbrk support for ARM, powerpc, mips, and sparc
735 and set them to default to the much faster brk using malloc
736 o Added missing syscalls: get_kernel_syms, fcntl64,
737 fdatasync, sched_setparam, sched_getparam,
