1.697 leitner 8: 0.34:
9: move stpcpy from libcompat to lib as it is now part of POSIX (Enrico Scholz)
1.698 leitner 10: add linux/seccomp.h linux/prctl.h linux/audit.h linux/elf-em.h linux/filter.h
1.699 leitner 11: SECURITY: make sure all assembler files mark the stack non-executable so
12: the kernel can map the stack of the whole program as non-executable
1.700 leitner 13: support compiling with clang (no cross compiling yet, and the resulting
14: binary code is significantly larger than with gcc)
15: implement experimental C11 threads
1.701 leitner 16: fix fgets (Andreas Förster)
1.702 leitner 17: add eventfd, inotify_init1, epoll_init1, accept4, recvmmsg, sendmmsg
18: add dup3, fanotify_init, fanotify_mark, signalfd4, timerfd_settime
1.703 leitner 19: add timerfd_gettime, setns, memfd_create, getrandom, syncfs
1.704 leitner 20: add preadv, pwritev
1.705 leitner 21: add getcontext, setcontext, makecontext, swapcontext (i386 and x86_64 only for now)
1.706 leitner 22: add implementation of hsearch and friends

1.716 leitner 34: add explicit_bzero, timingsafe_bcmp and timingsafe_memcmp (OpenBSD APIs useful for crypto)
1.717 leitner 35: i386 switched from mmap to mmap2. glibc has been doing this for ages,
36: and we now follow suit (without fallback to mmap), because
37: seccomp-filter can't inspect mmap arguments, so this helps security.

66: diet chooses depending on presence of -g
1.741 leitner 67: add mlock2
1.742 leitner 68: prefer gcc4+ __CAS implementation to our own on ARM, and fix ours (Philip Zander)
1.743 leitner 69: move _POSIX_MAPPED_FILES to unistd.h
70: accept "x" in fopen mode
1.697 leitner 71:
1.673 leitner 72: 0.33:
1.674 leitner 73: first stab at getting TLS to work in actual threads
74: use fs: to find current thread on x86_64
1.675 leitner 75: add fallocate, posix_fallocate

1.682 leitner 86: add WANT_VALGRIND_SUPPORT in dietfeatures.h. When #defined, the
87: startup code will check if the program is running under valgrind,
88: and if it is, the SIMD optimized string routines will switch back to
89: a slower version that does not generate valgrind false positives.
1.683 leitner 90: add WANT_LLMNR in dietfeatures.h. Now you can do "ping windowsbox"
91: and it works if that box runs win7 and trusts the LAN; the down side
92: is that LLMNR does not like the .local prefix, so DNS does zeroconf
93: lookup for unqualified names now, too.
1.684 leitner 94: add WANT_GNU_STARTUP_BLOAT in dietfeatures.h to support
95: program_invocation_short_name and program_invocation_name

1.576 leitner 214: put exception handling frames in read-only section on AMD64 and S/390
215: make sys/stat.h ILP64 compatible

1.577 leitner 217: whoops, strptime was completely broken, and noone noticed :-)
218: fix DNS resolver to only use shorter timeout for .local queries

1.580 leitner 222: when asking for an IPv6 address and there is an IPv4 address in
223: /etc/hosts but not an IPv6 address, return NO_DATA without

1.284 fefe 652: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.450 leitner 653: Michal Ludvig (SuSE) ported the diet libc to the x86_64 architecture (the
1.285 fefe 654: upcoming AMD Hammer chips!). You can't even buy the chips yet and
655: the diet libc already supports it! Amazing ;-)
656: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 657: Andre sent a patch to add ARM profiling. He says it does not work
658: yet, but it's a start.
1.287 fefe 659: added getdents64 backwards compatibility and include it in large file
660: support #defines
1.288 fefe 661: perror now checks if the message is NULL like glibc (Thomas Ogrisegg)

1.281 fefe 688:
1.264 fefe 689: 0.17:
1.265 fefe 690: fix several bugs in getservent_r
1.266 fefe 691: Gunnar Ritter reported the following:
692: moved tcgetpgrp and tcsetpgrp to unistd.h
693: adjusted lstat->lstat64 #define to make it work with function pointers
694: move __dietlibc__ #define from features.h to diet
1.267 fefe 695: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
696: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 697: Thomas also sent me profiling support (so far only on x86, but
698: profiling/PORTING describes what needs to be done for other
699: architectures)!
1.272 fefe 700: add contrib/dprof.c, also from Thomas.
1.269 fefe 701: Andreas Krennmair sent a patch to add the BSD regex interface to
702: libcompat
1.271 fefe 703: Andre noticed that __dtostr never sets first to false. Oops!
1.274 fefe 704: Andre has provided a largely untested patch that seems to fix the problem.
1.275 fefe 705: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 706: abort did not flush all stdio streams
1.277 fefe 707: fix some nasty regular expression bugs
708: write a stupid malloc checker (contrib/debug-realloc.c) to help me
709: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 710: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 711: fix DNS domain search
1.280 fefe 712: i386 memccpy exchanged esi and edi :-( I should do more checks before
713: accepting external code...
1.264 fefe 714:
1.244 fefe 715: 0.16:
716: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 717: Andre found two very embarassing bugs in my four lines of md5 glue.
718: I need to get more sleep.
1.247 fefe 719: Thanks Ogrisegg found that ptrace does not work as documented and
720: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 721: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
722: fix ptrace.h for S/390 and ARM
723: provide a PORTING document so we don't lose track of which file need
724: to be touched to port the diet libc to a new platform.
1.249 fefe 725: remove a few warnings
726: provide a prototype for usleep.
1.250 fefe 727: make __dtostr work on ARM by using long instead of long long.
728: Idea by Dirk Engling.
1.251 fefe 729: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 730: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 731: Kurt Garloff sent in patches to
732: fix struct termios on non-x86 architectures
1.254 fefe 733: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
734: create libcompat.a (and move daemon to it)
1.255 fefe 735: add getdelim and getline
736: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 737: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 738: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 739: Hans Lermen fixed i386/getenv.S
1.259 fefe 740: diet -Os no longer discards -fpic and -fno-pic
1.260 fefe 741: fix i386 rand/random to use correct RAND_MAX (thanks, Jaroslav
742: Macodiseas)
1.261 fefe 743: sys/ipc.h now includes sys/types.h
1.262 olaf 744: Olaf: started to make the sparc64 port
1.263 fefe 745: scandir should not sort if compar() is NULL (reported by Andrea Marrosu)
1.244 fefe 746:
1.224 fefe 747: 0.15:
1.225 fefe 748: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 749: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 750: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
751: thread-safe!
1.228 fefe 752: remove vfork and add alarm to dynamic syscalls.
753: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 754: The MD5 code generated unaligned accesses when passed an unaligned
755: pointer on little endian ARM and MIPS.
756: MIPS unified syscall didn't compile anymore.
757: Put up new mipsel target to cross compile for little endian mips.
758: The mips target will again explicitly set endianness to big endian.
759: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 760: Duh, when we removed return0, we broke tzset when the time zone parser
761: was disabled. Uwe Ohse noticed this. Thanks!
762: Fix gethostbyname to match host names case insensitively in /etc/hosts.
763: Oops, this was reported 6 weeks ago but I overlooked the email.
764: Thanks, Denis Rachal!
1.231 fefe 765: vsnprintf's zero termination was broken.
1.233 fefe 766: Uwe Ohse found a few more bugs:
767: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
768: does it correctly.
769: Make inet_aton use strtoul instead of strtol
770: fdopen would close the file descriptor if it could not malloc the
771: buffer.
772: strftime updates.
773: Make _FILE_OFFSET_BITS includes -Wundef clean
774: Andre found a typo in endian.h for big endian mips
1.234 fefe 775: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 776: strstr(whatever,"") returned NULL, not whatever. Found by a new test
777: suite entry for strstr that I wrote.
1.245 fefe 778: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 779: add <asm/sigcontext.h> for profiling support.
780: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 781: an i386 assembler getenv implementation (roughly half the size)
782: add grantpt, ptsname, unlockpt
1.236 fefe 783: add a getenv test suite entry.
1.238 fefe 784: Andre contributed an ARM assembler md5 implementation and he fixed mmap
785: on ARM.
786: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 787: getservent_r did not parse lines without aliases. Thanks, Jaroslav
788: Macodiseas!
1.240 fefe 789: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 790: removed annoying -Wconversion gcc switch
1.242 fefe 791: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 792: Kurt Garloff sent these diffs:
793: add fdatasync (and make it a pthread cancellation point)
794: numerous alpha issues, like using .quad instead of .long for
795: offsets, change strip to -strip in Makefile (so a failing strip does
796: not abort the make), try to be more friendly to the gcc 2.96 that
797: SuSE 7.1 AXP ships with.
1.224 fefe 798:
1.209 fefe 799: 0.14:
1.224 fefe 800: fix brk again (missing __brk, trivial oversight)
1.210 fefe 801: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
802: Thomas Ogrisegg!
1.211 fefe 803: Thomas also contributed a PA-RISC port including testandset, so
804: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 805: made the fake locale more believable.
806: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 807: moved _exit into the unified syscall on x86.
1.214 fefe 808: Uwe Ohse found many more bugs:
809: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
810: liblatin1 was more or less completely broken if you gave it chars as
811: arguments, not ints (signedness). execvp had a buffer overflow in
812: case a PATH element exceeded PATH_MAX, but it's not a security
813: problem since setuid programs need to set their path to some known
814: value anyway.
1.219 fefe 815: hasmntopt did not work with foo=bar style options
1.217 fefe 816: Uwe also improved ftw's stack usage.
1.214 fefe 817: Put movl instead of popl rationale in comment in i386/unified.S since
818: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 819: I discovered __attribute__((malloc)) and started using it. For gcc 3,
820: it improves the optimizer when functions return malloced pointers.
1.216 fefe 821: Steven Rostedt pointed out that my setvbuf was broken with regard to
822: size==0 and sent a patch to fix it.
1.218 fefe 823: Thomas Ogrisegg made setenv smaller.
1.220 olaf 824: Olaf: implemented the parisc clone and an atomic testandset, modified the
825: libpthread to respect the parisc UPgrowing stack. still non functional,
826: because the unified syscall uses errno :(
1.221 fefe 827: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 828: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
829: don't write anything which was no longer the case. It also
830: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 831: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 832:
1.193 fefe 833: 0.13:
1.194 fefe 834: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 835: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 836: Olaf: port to S/390!
1.463 leitner 837: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 838: res_query did not initialize last
1.199 fefe 839: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 840: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 841: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 842: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 843: rewrote __dtostr (it also has one more argument now)
1.205 fefe 844: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 845: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
846: fix strncat for the case where n == 0 (security implications?)
847: fix bsearch (it didn't find the very last element in the array, same
848: bug in both the C and the i386 assembly version).
1.205 fefe 849: fixed FNM_PATHNAME in fnmatch
1.204 fefe 850: fix brk (the syscall was documented incorrectly in the Linux man page)
851: Thanks, Thomas Ogrisegg!
1.205 fefe 852: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 853: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 854: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 855:
1.164 fefe 856: 0.12:
857: more contributions from Frank Klemm.
1.165 fefe 858: iconv can now do UCS-2, too.
1.167 fefe 859: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 860: Lots of bug fixes, and several more i386 specific versions of common
861: routines to make them smaller.
1.168 fefe 862: add memmem (a GNU extension that looks useful)
1.170 fefe 863: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 864: add pivot_root syscall, %n for *scanf.
1.169 fefe 865: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 866: add Frank Klemm's optimized md5
1.172 fefe 867: add -Os option to diet (see diet.1).
1.173 fefe 868: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 869: add 32-bit uid/gid syscalls.
1.175 fefe 870: add rand48 (thanks, Johannes Kloos)
1.176 fefe 871: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 872: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
873: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
874: fix gethostent alias list termination. Major oops.
1.178 fefe 875: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 876: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 877: DNS will now properly signal errors and set h_errno.
878: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 879: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
880: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
881: external reference to a symbol that is only in the diet libc. So,
882: when you accidentally link a diet libc compiled object file against
883: glibc, the linker will barf. This will bloat your object files, but
884: you can remove all the references with "strip -R .note" from
885: the binaries in the end (which you should do anyway).
1.182 fefe 886: fix ARM unified syscall (select did not work).
1.183 fefe 887: add getpwent_r ala glibc and replace getpwent
888: do the same for getgrent and getspent
889: remove entlib (new code is smaller)
1.184 fefe 890: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 891: add getpwnam_r and getpwuid_r
1.186 fefe 892: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 893: Olaf muddled with the dynamic linker. It's a clean-room
894: implementation in the sense that it once worked for Olaf in a clean
895: room ;)
1.188 fefe 896: add if_nameindex and if_freenameindex.
897: fixed arm unified syscalls to work with current binutils (; is no
898: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 899: changed all st_[cma]time types to signed long so comparisons against
900: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 901: fixed two bugs regarding ungetc.
902: add getusershell, setusershell, endusershell (for vs_ftpd)
903: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 904: fixed strftime (was completely hosed)
1.192 fefe 905: added real make install target
1.164 fefe 906:
1.115 fefe 907: 0.11:
908: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 909: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 910: add floor, ceil and memchr prototypes.
911: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 912: cleaner errno vs __errno_location handling
913: add placeholder iconv (iconv_open will always return EINVAL)
914: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
915: initialization of getaddrinfo.
1.119 fefe 916: fix vsnprintf %X (printed lower case)
1.120 fefe 917: I wrote a new getopt. It appears to actually work (it is POSIX
918: compliant, it does not sort argv like the GNU version) and is only
919: a little over 300 bytes on x86.
1.121 fefe 920: Guillaume Cottenceau just wrote me that strncat should be even more
921: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 922: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 923: Fix regexec offset return. autoconf now believes that diet libc has
924: POSIX regular expressions.
1.123 fefe 925: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 926: Fix regular expression match for x* when there is no x at all.
1.668 leitner 927: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pr?pper.
1.126 fefe 928: Add %h to vsnprintf.
1.127 fefe 929: Add FAQ.
1.128 fefe 930: Make %h work for signed numbers and add %hh to vsnprintf.
931: initgroups ignored the group argument :-(
932: remove printf references and nested functions from glob.
1.129 fefe 933: added an errno in libpthread that will display a prominent linker
934: warning.
1.131 fefe 935: started getting rid of kernel headers. Big task! :-(
1.130 fefe 936: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 937: Olaf: added a lot of code in libdl (not yet complete), changed the
938: startup code to make it work with his libdl and ld.so (needs still work
939: too)
1.134 fefe 940: __dns_readstartfiles only took the first domain or search path.
941: Thanks, Anthony de Boer
1.133 olaf 942: Olaf: added clone and a new unified_syscall for PowerPC
943: also dynlinker is now available (i386 only at this time)
1.135 fefe 944: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 945: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 946: fixed word delimiters in regex (they looked for space, i.e. "," did
947: not work as delimiter)
1.138 fefe 948: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 949: added mkdtemp.
1.142 fefe 950: Uwe Ohse reported all of the following bugs:
951: ttyname should return 0 if !isatty.
952: realpath returns NULL if "." cannot be opened
953: putenv erroneously accepted (and mishandled) entries without "=".
954: popen returned 255 instead of 127 if /bin/sh could not be run.
955: fgetc did not set the internal EOF indicator on EOF.
956: bsearch contained an assumption about integer arithmetic overflow
957: behavior.
958: system did not set SIGCHLD and thus contained a race.
959: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 960: daemon did not check whether open returns an fd below 3
961: perror did not save errno.
1.144 olaf 962: Olaf: Peter Jones reported some problems with perror; strerror had the
963: same problem.
964: Peter also posted a patch to atexit/exit. With some modifications it is
965: now implemented.
1.145 fefe 966: Unbuffered stdio and ungetc can no longer be disabled. I will try to
967: implement part of it using ELF weak symbols.
1.146 fefe 968: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 969: Added overflow handling for strtoul and strtol.
1.149 fefe 970: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
971: it before falling back to DNS if enabled.
1.150 fefe 972: Added a littie backwards compatibility cruft for gpm (man, do these
973: sources stink!)
1.151 fefe 974: Added openpty.
1.152 fefe 975: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 976: Fix fseek return value.
1.155 fefe 977: Add dirname and basename.
1.156 fefe 978: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 979: Fixed getservent (did not allow _ and - in the aliases).
980: Thanks, Oden Eriksson
1.158 fefe 981: Added a float.h so configure believes we have ANSI header files.
982: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 983: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 984: scanf and printf function implementations
1.160 fefe 985: Imported a few more functions and optimizations from Frank Klemm (he
986: also rewrote dtostr to have more precision)
1.161 olaf 987: Olaf: checked in a new sig* function family (based on rt_sig*).
988: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 989: Made rudimentary iconv that can convert back and forth between
990: iso-8859-1, utf-8 and ucs-4 (for debugging).
991: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 992:
1.74 fefe 993: 0.10:
994: update getpagesize.
995: add personality.
1.75 fefe 996: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 997: add putchar (apparently arm-linux-gcc will substitute printf("\n")
998: with putchar('\n') behind your back...?!
1.77 fefe 999: import include/scsi/ from glibc.
1.78 fefe 1000: add iopl.
1.80 fefe 1001: add execl and sigdelset prototypes.
1002: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 1003: add RPC headers (no code yet).
1.82 fefe 1004: add mlockall, munlockall
1.83 fefe 1005: make "diet gcc foo.c" work.
1006: added Sun RPC code and removed as many warnings as possible in a
1007: heroic act of self-mutilation.
1008: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 1009: added getpass. mount from util-linux actually compiles now!
1010: fix the sig*set routines. mount actually works now *bg*
1011: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 1012: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 1013: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 1014: add res_init.
1015: add asprintf (ugh, what an ugly function).
1.89 fefe 1016: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 1017: add ut_name alias to ut_host in struct utmp.
1018: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 1019: add sysinfo, recvmsg, sendmsg.
1.93 fefe 1020: add endmntent, getmntent, setmntent.
1.94 fefe 1021: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 1022: add setenv.
1023: remove __restrict from mntent.h, add __restrict__ removal alias for
1024: older gcc versions in sys/cdefs.h.
1025: add rlim_t, sig_atomic_t declarations.
1026: add sigsetjmp #define for __sigsetjmp (oops).
1027: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 1028: add a gruesome hack to printf floating point to accept %f and kludge
1029: together support for %.2f. Don't look at the code, please!
1.98 fefe 1030: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 1031: imported fix for entlib by Jeff Garzik.
1.100 fefe 1032: add glob implementation from Guillaume Cottenceau (Thanks!!)
1033: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 1034: add REG_ICASE and word start/end handling to my regular expressions.
1035: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 1036: wrap getcwd to comply to man page (the syscall returns the number of
1037: bytes, not the buffer)
1038: add realpath.
1.103 fefe 1039: fix vfprintf.
1.104 fefe 1040: fix *scanf %s zero termination.
1041: add abs, labs, llabs.
1.105 fefe 1042: add <sys/io.h>, ioperm syscall.
1043: add flock to <sys/file.h>
1.106 fefe 1044: fixes to bsearch and the regular expressions.
1.107 fefe 1045: add fake herror.
1.108 fefe 1046: add scandir and alphasort.
1.109 fefe 1047: add killpg
1.110 fefe 1048: implemented a gross hack to make libpthread compile when
1049: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 1050: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 1051: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 1052: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
1053: for sending a patch.
1.114 fefe 1054: add getserv*.
1055: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
1056: "search" from resolv.conf.
1.74 fefe 1057:
1.73 fefe 1058: 0.9:
1.65 fefe 1059: fixed initgroups (oops)
1.66 fefe 1060: Cleanup appending file open for stdio (thanks, James Antill)
1061: imported vfprintf fix from James Antill.
1.67 fefe 1062: add fnmatch
1063: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 1064: Olaf added character classes to *scanf.
1.69 fefe 1065: Put object and library files into a separate directory (bin-$ARCH).
1066: Add "cross" make target to make all architectures.
1067: Add "diet" program and man page.
1.70 fefe 1068: Add getgrnam, getgrgid
1.71 fefe 1069: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 1070: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 1071:
1.64 fefe 1072: 0.8:
1.34 fefe 1073: vsnprintf(0,...) estimated the length of strings with a padding width
1074: incorrectly.
1.35 fefe 1075: new reboot() from Olaf.
1.36 fefe 1076: added prototypes for getsockopt and setsockopt.
1.39 fefe 1077: added experimental sem* and shm*
1.38 fefe 1078: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 1079: added setvbuf (only changes mode, not buffer)
1.41 fefe 1080: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
1081: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 1082: added qsort() and bsearch(). Benchmark on 1000 random ints:
1083: glibc: 679414 cycles qsort and 3352 cycles bsearch
1084: diet libc: 300010 cycles qsort, 553 cycles bsearch
1085: I have no idea why glibc is so slow.
1.43 fefe 1086: added __isnan (references by libm.a from glibc).
1087: added popen() and pclose(). Now the diet libc can link slsh (from
1088: S-Lang!)
1.44 fefe 1089: corrected usleep. It was more of an msleep until now.
1.45 fefe 1090: corrected __dtostr (it looped when trying to format "0.0").
1091: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 1092: added ungetc (does it work?)
1.47 fefe 1093: added inet_aton (yuck!)
1.50 fefe 1094: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 1095: added h_errno and __h_errno_location
1096: added inet_ntoa
1.49 fefe 1097: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 1098: add bcopy, index, rindex macros
1099: add isgraph and isxdigit
1.52 fefe 1100: add strftime (ugh!!!)
1.53 olaf 1101: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 1102: Jeff Garzik contributed a spec file. I put it in contrib and hope
1103: everbody knows what to do with it...
1104: Olaf checked in a ton of libpthread stuff.
1.55 fefe 1105: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 1106: add large file backwards compatibility support (so gzip will run on
1107: kernel 2.2 and 2.0)
1.57 fefe 1108: added shutdown
1.58 fefe 1109: added nice
1110: added pseudo-locale support for is* (they are now weak aliases,
1111: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
1112: overwrite the default is* functions.
1.59 fefe 1113: added liblatin1.a
1.60 fefe 1114: added tzfile implementation (does it work for anyone else?)
1.668 leitner 1115: added syslog(3) (thanks to Rene M?ller!)
1.62 fefe 1116: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
1117: Thanks!
1.63 fefe 1118: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 1119:
1.21 fefe 1120: 0.7.2:
1121: added several prototypes to already implemented functions and
1122: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 1123: added prototypes for process group and dup syscalls. Thanks to
1124: Abraham again. He also contributed an implementation for daemon(),
1125: an ugly BSD hack. I decided to diversify the lib/ directory a
1126: little and now created a libugly/ directory for stuff like system()
1127: and daemon() ;-)
1128: added libstdio and moved all that stdio crap from lib/ there. The
1129: idea is to start separating now what we will separate for shared
1130: libraries anyway.
1.26 fefe 1131: optimized x86 unified-syscall by Olaf.
1.27 fefe 1132: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
1133: limits.h instead)
1134: added remove.c and enough cruft to limits.h to make it compile lzo,
1135: lzop and bzip2.
1.28 fefe 1136: added mktime, asctime_r, asctime and ctime (needed for gzip).
1137: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 1138: format some day (man tzfile, ugh!) :-(
1.29 fefe 1139: added unlink prototype to unistd.h.
1140: added gmtime and gmtime_r.
1.31 fefe 1141: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 1142: removed readdir glibc compatibility cruft.
1.31 fefe 1143: removed stat glibc compatibility cruft.
1.32 fefe 1144: oops, my fread was broken for pipes.
1.33 fefe 1145: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 1146:
1.9 fefe 1147: 0.7.1:
1.11 fefe 1148: optimized away the static arrays from __ltostr and __lltostr.
1149: optimized away the static arrays (and more!) from strtoul and strtoull.
1150: added system (by Olaf).
1.12 fefe 1151: added tolower and toupper
1.13 fefe 1152: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 1153: added clone for mips (by Olaf).
1154: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 1155: added pause for all (by Olaf).
1.17 fefe 1156: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 1157: added isupper and islower.
1158: added putc and putchar as macros.
1.17 fefe 1159: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
1160: insightful discussions and patches I partially used for the last three)
1.18 fefe 1161: added getpriority and setpriority (also by Abraham)
1.19 fefe 1162: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 1163: oi, setjmp and longjmp were broken on other platforms, too!
1.668 leitner 1164: Thanks to S?bastien C?t? for reporting this.
1.9 fefe 1165:
1166: 0.7:
1.6 olaf 1167: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 1168: Initial dynamic loading glue for i386, also by Olaf.
1169: We don't have a dynamic loader yet, so this is not yet usable.
1170: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
1171: vsprintf, writev, all by Olaf.
1.2 fefe 1172: imported readdir fix from Guillaume. Mhh, can the kernel interface
1173: really be this broken?
1.3 fefe 1174: Found a kludgy way to detect whether the kernel includes define struct
1175: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
1176: not work for you, please tell me!
1.4 fefe 1177: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 1178: Fixed stdio line buffering. The code was already there but I forgot
1179: to mark stdio and stdout as line buffered. This should really be
1180: done dynamically using isatty, though.
1.8 fefe 1181: Removed superfluous "if (1)" in execvp.c
1.1 cvs 1182:
1183: 0.6.14:
1184: *scanf did not append the 0 byte for %s.
1185: added creat and changed creat to call open directly instead of open64.
1186: did for fread what 0.6.10 did for fwrite.
1187: repaired buffered stdio a little (line buffering is still not
1188: supported).
1189: [All of these bugs have been reported by Guillaume. Thanks!]
1190: added __pure__ to strchr and strrchr in <string.h>
1191:
1192: 0.6.13:
1193: included COPYING to make clear that the diet libc is covered by the
1194: GNU General Public License (and _not_ the LGPL). That means that
1195: you need to obtain a license from me if you want to use the diet
1196: libc in a proprietary program that you want to distribute.
1197: The x86 unified syscall swapped arguments #4 and #5 and noone
1198: noticed until now! Thanks to Guillaume Cottenceau for reporting
1199: this!
1200: The malloc had a subtle bug with small allocations that could cause
1201: segfault. Guillaume reported it, Olaf fixed it.
1202:
1203: 0.6.12:
1204: added assert, statfs and fstatfs
1205: added include/net/if.h so fget compiles again.
1206:
1207: 0.6.11:
1208: added putenv.
1209:
1210: 0.6.10:
1211: fixed fwrite. It returned the number of bytes written, not the number
1212: of records. Thanks to Albert D. Cahalan for pointing this out.
1213: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
1214: added brk and sbrk. harold@nb.com.sg made me do it.
1215:
1216: 0.6.9:
1217: fixed execvp not to return on ENOENT
1218: did for {open|read|close|seek|tell}dir what I did for stat before.
1219: The glibc compatibility part is currently non-functional.
1220: fixed white space handling in sscanf " (" would not match " (".
1221: fixed printf to accept 'l' flag.
1222: fixed getpwuid (ignored last line)
1223:
1224: 0.6.8:
1225: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
1226: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
1227: added strlcpy and strlcat from OpenBSD.
1228: added stat64, fstat64 and lstat64.
1229: added endian.h and made ending of strlen.c endianness-aware
1230: added string routines size tweak to dietfeatures.h. Most of the
1231: string routines have been unrolled. This is up to three times as
1232: fast but creates up to three times larger code. Now you can disable
1233: the unrolling.
1234: added sendfile.
1235: I also added pread. It works on x86 and sparc but not on ppc and mips.
1236: I have no idea what's going on. strace disagrees with the kernel.
1237: Can anyone help? I asked the Linux kernel mailing list for help, too.
1238: added a few aliases of the type __libc_open for open. nm on
1239: libpthreads.so indicates that we will need them.
1240:
1241: 0.6.7:
1242: the sources now compile without warnings with -Wall.
1243: printf now prints "(null)" when %s is passed NULL. This can be
1244: removed with WANT_NULL_PRINTF in dietfeatures.h
1245: added vfprintf, execl, ttyname.
1246: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
1247: __dietfstat so they can use the normal kernel struct stat.
1248: stat, lstat and fstat are now C wrappers that convert to the glibc
1249: struct stat. So we can avoid that overhead for programs that use
1250: dietlibc headers.
1251:
1252: 0.6.6:
1253: changed the Makefiles so you can now set CFLAGS on the command line
1254: added memccmp (analogous to memccpy) and strncmp.
1255: Olaf fixed another bug in the sparc unified syscall.
1256: Paul Clifford contributed a C version of his strlen.S that is much
1257: more efficient than the previous strlen on all platforms! It also
1258: looks like technology from Roswell. ;-}
1259: added a "real" stdio. Well, almost. Please contribute!
1260: added dietfeatures.h so you can remove features you don't need.
1261: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
1262: stdio now works with simple programs and minigzip from libz.
1263: stdio uses some major trickery to avoid linking the stdio, stderr and
1264: stdout (and reserving space for them) when they are not used.
1265:
1266: 0.6.5:
1267: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
1268: most of them bugs in the new header files, but also missing sigset
1269: functions.
1270: Paul Clifford contributed an assembly strlen.S for ARM and fixed
1271: several bugs.
1272: Fixed ppc/setjmp and mips/pipe.
1273: Olaf contributed a new sparc unified syscall.
1274:
1275: 0.6.4:
1276: declared is* static inline in getservent.
1277: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
1278: changed strlen to return 0 when passed NULL.
1279: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
1280: Scientist who actually implemented this without access to a MIPS
1281: box, just from reading the architecture manual. And it worked out
1282: of the box.
1283: started a set of system includes, mainly so that I can use lcc and
1284: my alpha-linux cross compiler (which is unable to cross-compile
1285: glibc). diet libc can now be compiled without any include files
1286: from a normal libc. The includes do declare more than diet libc
1287: currently delivers and they are still far from complete for real
1288: applications.
1289: I will only add assembly versions that are smaller _and_ faster than
1290: the C version. Larger routines are only accepted if they are called
1291: very often and are substantially faster.
1292: added i386 assembly strchr, which is smaller and faster than the old
1293: version. It is, however, larger than the version contributed by
1294: proton (thanks, anyway).
1295: added i386 strlen (31% faster, 14% smaller)
1296: "make t" will now create a map file called "mapfile".
1297:
1298: 0.6.3:
1299: added sys_errlist, strerror and perror
1300: added isblank
1301: added atol
1302:
1303: 0.6.2:
1304: mmap for ARM didn't compile. Thanks, Paul!
1305:
1306: 0.6.1:
1307: split mmap into the architecture specific subdirectories.
1308: getenv now copes with environ==NULL, thanks Paul Clifford.
1309: Paul also contributed a smaller ARM startup code.
1310:
1311: 0.6:
1.668 leitner 1312: strcat returned the wrong result. Thanks, Dietz Pr?pper.
1.1 cvs 1313: strtod now understands a negative exponent (oops, thanks Bertram Barth)
1314: Port to arm-linux-gnu, but on the Netwinder I use for testing the
1315: __dtostr does not work (I have no idea why!)
1316: The MIPS port now uses (much smaller) non-PIC code. That means that
1317: the applications you link against diet libc also have to be compiled
1318: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
1.668 leitner 1319: Thanks to Ralf B?chle for helping me with this!
1.1 cvs 1320: I made subdirectories for the architectures and use VPATH to override
1321: VPATH so that make finds the source file automatically. That should
1322: simplify the sources greatly.
1323: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
1324: ARM and MIPS now also have setjmp and longjmp
1325: "compile" and "load" are now make targets. Use them for djb programs.
1326: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1327: Again, contributed from Olaf. Great work!
1328:
1329: 0.5.12:
1330: printf also does signed numbers.
1331: If you don't use atexit, dietlibc now does not link exit, only _exit.
1332: *printf now correctly returns the number of bytes written.
1333: Olaf contributed experimental sscanf and vsscanf implementations.
1334: If passed NULL as buffer, snprintf will not write anything but still
1335: return the number of bytes it would have written.
1336: Initial MIPS port! (Oh, the agony!)
1337: No setjmp and longjmp support yet! Please contribute!
1338: I even implemented unified syscalls for MIPS. Still, MIPS code is
1339: almost twice the size of SPARC code. If anyone knows why: please
1340: tell me!
1341:
1342: 0.5.11:
1343: I implemented new unified syscalls for x86, sparc and ppc, this time based
1344: on .s files and not .c files, and I moved the syscalls into
1345: subdirectores to clean the dietlibc sources up a little.
1346: A binary consisting of printf("%s is %d\n","olaf",23) is now
1347: 2864 bytes on sparc
1348: 2488 bytes on intel
1349: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1350: to make a few more applications work.
1351: Olaf Dreesen also implemented some unified syscall stuff for x86.
1352: He discovered that with our unified syscall interface it actually
1353: costs <10 bytes total to make all system calls thread safe!
1354: I implemented atexit() (can register up to 4 callbacks).
1355: I implemented strtod and __dtostr (the opposite). Now we can add
1356: floating point support to vsnprintf and sscanf!
1357:
1358: 0.5.10:
1359: I actually saw that I can not only merge the errno handling code of
1360: the system calls on x86, I can also merge the rest (including the
1361: arguments) except for setting the system call number. All those
1362: system calls are now just a jump to a unified system call handler.
1363: I got rid of x86openclose again. The savings are substantial:
1364: chown from embutils went from 7664 to 7184 bytes!
1365: If I'd move the system call wrappers to assembly language, I could
1366: even reduce the alignment (does not matter since it's just a jump
1367: anyway) and get rid of the "ret" behind each jump (one byte per
1368: system call!)
1369:
1370: 0.5.9:
1371: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1372: fixed strdup
1373: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1374: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1375: (no signed integers, only strings and unsigned integers (but
1376: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1377: that code must be wonderful, I don't understand it at all *bg*)
1378: Olaf's printf does understand padding like in "%08d" and "%8d" and
1379: automatically pads pointers with '0'.
1380: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1381: Thanks to proton for inspiration on this.
1382: The new x86 start code also does not reference exit any more, thus saving
1383: 64 bytes for executables that don't call exit explicitly.
1384: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1385: Moved errno and environ to start.S, saving no byte binary size but
1386: speeding up compilation and slightly shortening dietlibc.a ;-)
1387: For x86: joined open and close into one assembler file, sharing the
1388: errno handling. This is a feasibility test and it actually saves a
1389: few bytes. I think I will reimplement the _syscall[1-6] macros on
1390: all platforms now to share the errno handling code for them.
1391:
1392: 0.5.8:
1393: fixed strchr to be able to look for 0.
1394:
1395: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1396: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1397: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1398: contributed by Olaf Dreesen)
1399:
1400: added execvp, getcwd
1401:
1402: fixed __xmknod
1403:
1404: Note: can it be that the ftw interface really is so broken that I
1405: cannot implement it without having to implement some searching data
1406: structure? I included an experimental ftw implementation that will
1407: not follow symlinks.
1408:
1409: 0.5.7:
1410: oops, if_nametoindex was broken!
1411:
1412: 0.5.6:
1413: ported to ppc-linux.
1414: fixed i386 sigsetjmp (I mistyped the function name)
1415: included sigjmp.c
1416:
1417: 0.5.5:
1418: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1419: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1420: I fixed it now.
1421: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1422: fixed readdir to use getdents and not the intel inline asm
1423:
1424: 0.5.4:
1425: ported to sparclinux (sparc32 only). Beware: does not work yet.
1426: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1427:
1428: 0.5.3:
1429: added tcsetattr and getenv to compile e3
1430:
1431: 0.5.2:
1432: added vhangup, tcgetattr, isatty and memcmp for fgetty
1433: (http://www.fefe.de/fgetty/)
1434: added localtime from uC-libc.
1435:
1436: 0.5.1:
1437: stat and friends actually work now. Yuck! Another case of
1438: translation between kernel and userland. Why can't the kernel
1439: people and the libc people simply agree on a standard?
1440: removed many unnecessary includes to speed up compilation.
1441: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1442: inlined socketcall to reduce code size.
1443: "load" and "compile" are examples for djb code.
1444:
1445: 0.5:
1446: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1447: each object file is now treated with "strip -x -R .note -R .comment"
1448: split each system call into a separate object file
1449: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1450:
1451: 0.4.1:
1452: oops, the strchr implementation was wrong. Thanks Jens Laas!
1453:
1454: 0.4:
1455: copied opendir and friends from uC-libc.
1456: added getservent and getservby* in gerservent.c
1457:
1458: 0.3:
1459: remove readdir system call
1460: added getdents system call
1461: added getpwnam/getpwuid implementation in getpwnam.c
1462: added a few string functions (in str*.c)
