1.698 leitner 18: add linux/seccomp.h linux/prctl.h linux/audit.h linux/elf-em.h linux/filter.h
1.699 leitner 19: SECURITY: make sure all assembler files mark the stack non-executable so
20: the kernel can map the stack of the whole program as non-executable
1.700 leitner 21: support compiling with clang (no cross compiling yet, and the resulting
22: binary code is significantly larger than with gcc)
23: implement experimental C11 threads
1.701 leitner 24: fix fgets (Andreas Förster)
1.702 leitner 25: add eventfd, inotify_init1, epoll_init1, accept4, recvmmsg, sendmmsg

1.716 leitner 42: add explicit_bzero, timingsafe_bcmp and timingsafe_memcmp (OpenBSD APIs useful for crypto)
1.717 leitner 43: i386 switched from mmap to mmap2. glibc has been doing this for ages,
44: and we now follow suit (without fallback to mmap), because
45: seccomp-filter can't inspect mmap arguments, so this helps security.

74: diet chooses depending on presence of -g
1.741 leitner 75: add mlock2
1.742 leitner 76: prefer gcc4+ __CAS implementation to our own on ARM, and fix ours (Philip Zander)
1.743 leitner 77: move _POSIX_MAPPED_FILES to unistd.h
78: accept "x" in fopen mode
1.697 leitner 79:
1.673 leitner 80: 0.33:

1.682 leitner 94: add WANT_VALGRIND_SUPPORT in dietfeatures.h. When #defined, the
95: startup code will check if the program is running under valgrind,
96: and if it is, the SIMD optimized string routines will switch back to
97: a slower version that does not generate valgrind false positives.
1.683 leitner 98: add WANT_LLMNR in dietfeatures.h. Now you can do "ping windowsbox"
99: and it works if that box runs win7 and trusts the LAN; the down side
100: is that LLMNR does not like the .local prefix, so DNS does zeroconf
101: lookup for unqualified names now, too.
1.684 leitner 102: add WANT_GNU_STARTUP_BLOAT in dietfeatures.h to support
103: program_invocation_short_name and program_invocation_name

1.694 leitner 120: add openat and friends
1.695 leitner 121: srand(0) made rand() return a series of 0 instead of random data
122: (https://banu.com/blog/42/openbsd-bug-in-the-random-function/)
1.696 leitner 123: add SO_RCVBUFFORCE and SO_SNDBUFFORCE

657: check in mktime fix (from Luc Van Oostenryck)
1.283 fefe 658: add libm2.s from contrib to i386 (oops, how long has it been sitting
659: there?)
1.284 fefe 660: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.450 leitner 661: Michal Ludvig (SuSE) ported the diet libc to the x86_64 architecture (the
1.285 fefe 662: upcoming AMD Hammer chips!). You can't even buy the chips yet and
663: the diet libc already supports it! Amazing ;-)
664: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 665: Andre sent a patch to add ARM profiling. He says it does not work
666: yet, but it's a start.
1.287 fefe 667: added getdents64 backwards compatibility and include it in large file
668: support #defines
1.288 fefe 669: perror now checks if the message is NULL like glibc (Thomas Ogrisegg)

1.307 fefe 695: cleanups from Florian LaRoche
1.281 fefe 696:
1.264 fefe 697: 0.17:
1.265 fefe 698: fix several bugs in getservent_r
1.266 fefe 699: Gunnar Ritter reported the following:
700: moved tcgetpgrp and tcsetpgrp to unistd.h
701: adjusted lstat->lstat64 #define to make it work with function pointers
702: move __dietlibc__ #define from features.h to diet
1.267 fefe 703: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
704: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 705: Thomas also sent me profiling support (so far only on x86, but
706: profiling/PORTING describes what needs to be done for other
707: architectures)!
1.272 fefe 708: add contrib/dprof.c, also from Thomas.
1.269 fefe 709: Andreas Krennmair sent a patch to add the BSD regex interface to
710: libcompat
1.271 fefe 711: Andre noticed that __dtostr never sets first to false. Oops!
1.274 fefe 712: Andre has provided a largely untested patch that seems to fix the problem.
1.275 fefe 713: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 714: abort did not flush all stdio streams
1.277 fefe 715: fix some nasty regular expression bugs
716: write a stupid malloc checker (contrib/debug-realloc.c) to help me
717: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 718: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 719: fix DNS domain search
1.280 fefe 720: i386 memccpy exchanged esi and edi :-( I should do more checks before
721: accepting external code...
1.264 fefe 722:
1.244 fefe 723: 0.16:
724: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 725: Andre found two very embarassing bugs in my four lines of md5 glue.
726: I need to get more sleep.
1.247 fefe 727: Thanks Ogrisegg found that ptrace does not work as documented and
728: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 729: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
730: fix ptrace.h for S/390 and ARM
731: provide a PORTING document so we don't lose track of which file need
732: to be touched to port the diet libc to a new platform.
1.249 fefe 733: remove a few warnings
734: provide a prototype for usleep.
1.250 fefe 735: make __dtostr work on ARM by using long instead of long long.
736: Idea by Dirk Engling.
1.251 fefe 737: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 738: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 739: Kurt Garloff sent in patches to
740: fix struct termios on non-x86 architectures
1.254 fefe 741: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
742: create libcompat.a (and move daemon to it)
1.255 fefe 743: add getdelim and getline
744: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 745: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 746: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 747: Hans Lermen fixed i386/getenv.S
1.259 fefe 748: diet -Os no longer discards -fpic and -fno-pic
1.260 fefe 749: fix i386 rand/random to use correct RAND_MAX (thanks, Jaroslav
750: Macodiseas)
1.261 fefe 751: sys/ipc.h now includes sys/types.h
1.262 olaf 752: Olaf: started to make the sparc64 port
1.263 fefe 753: scandir should not sort if compar() is NULL (reported by Andrea Marrosu)
1.244 fefe 754:
1.224 fefe 755: 0.15:
1.225 fefe 756: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 757: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 758: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
759: thread-safe!
1.228 fefe 760: remove vfork and add alarm to dynamic syscalls.
761: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 762: The MD5 code generated unaligned accesses when passed an unaligned
763: pointer on little endian ARM and MIPS.
764: MIPS unified syscall didn't compile anymore.
765: Put up new mipsel target to cross compile for little endian mips.
766: The mips target will again explicitly set endianness to big endian.
767: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 768: Duh, when we removed return0, we broke tzset when the time zone parser
769: was disabled. Uwe Ohse noticed this. Thanks!
770: Fix gethostbyname to match host names case insensitively in /etc/hosts.
771: Oops, this was reported 6 weeks ago but I overlooked the email.
772: Thanks, Denis Rachal!
1.231 fefe 773: vsnprintf's zero termination was broken.
1.233 fefe 774: Uwe Ohse found a few more bugs:
775: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
776: does it correctly.
777: Make inet_aton use strtoul instead of strtol
778: fdopen would close the file descriptor if it could not malloc the
779: buffer.
780: strftime updates.
781: Make _FILE_OFFSET_BITS includes -Wundef clean
782: Andre found a typo in endian.h for big endian mips
1.234 fefe 783: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 784: strstr(whatever,"") returned NULL, not whatever. Found by a new test
785: suite entry for strstr that I wrote.
1.245 fefe 786: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 787: add <asm/sigcontext.h> for profiling support.
788: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 789: an i386 assembler getenv implementation (roughly half the size)
790: add grantpt, ptsname, unlockpt
1.236 fefe 791: add a getenv test suite entry.
1.238 fefe 792: Andre contributed an ARM assembler md5 implementation and he fixed mmap
793: on ARM.
794: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 795: getservent_r did not parse lines without aliases. Thanks, Jaroslav
796: Macodiseas!
1.240 fefe 797: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 798: removed annoying -Wconversion gcc switch
1.242 fefe 799: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 800: Kurt Garloff sent these diffs:
801: add fdatasync (and make it a pthread cancellation point)
802: numerous alpha issues, like using .quad instead of .long for
803: offsets, change strip to -strip in Makefile (so a failing strip does
804: not abort the make), try to be more friendly to the gcc 2.96 that
805: SuSE 7.1 AXP ships with.
1.224 fefe 806:
1.209 fefe 807: 0.14:
1.224 fefe 808: fix brk again (missing __brk, trivial oversight)
1.210 fefe 809: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
810: Thomas Ogrisegg!
1.211 fefe 811: Thomas also contributed a PA-RISC port including testandset, so
812: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 813: made the fake locale more believable.
814: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 815: moved _exit into the unified syscall on x86.
1.214 fefe 816: Uwe Ohse found many more bugs:
817: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
818: liblatin1 was more or less completely broken if you gave it chars as
819: arguments, not ints (signedness). execvp had a buffer overflow in
820: case a PATH element exceeded PATH_MAX, but it's not a security
821: problem since setuid programs need to set their path to some known
822: value anyway.
1.219 fefe 823: hasmntopt did not work with foo=bar style options
1.217 fefe 824: Uwe also improved ftw's stack usage.
1.214 fefe 825: Put movl instead of popl rationale in comment in i386/unified.S since
826: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 827: I discovered __attribute__((malloc)) and started using it. For gcc 3,
828: it improves the optimizer when functions return malloced pointers.
1.216 fefe 829: Steven Rostedt pointed out that my setvbuf was broken with regard to
830: size==0 and sent a patch to fix it.
1.218 fefe 831: Thomas Ogrisegg made setenv smaller.
1.220 olaf 832: Olaf: implemented the parisc clone and an atomic testandset, modified the
833: libpthread to respect the parisc UPgrowing stack. still non functional,
834: because the unified syscall uses errno :(
1.221 fefe 835: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 836: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
837: don't write anything which was no longer the case. It also
838: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 839: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 840:
1.193 fefe 841: 0.13:
1.194 fefe 842: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 843: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 844: Olaf: port to S/390!
1.463 leitner 845: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 846: res_query did not initialize last
1.199 fefe 847: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 848: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 849: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 850: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 851: rewrote __dtostr (it also has one more argument now)
1.205 fefe 852: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 853: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
854: fix strncat for the case where n == 0 (security implications?)
855: fix bsearch (it didn't find the very last element in the array, same
856: bug in both the C and the i386 assembly version).
1.205 fefe 857: fixed FNM_PATHNAME in fnmatch
1.204 fefe 858: fix brk (the syscall was documented incorrectly in the Linux man page)
859: Thanks, Thomas Ogrisegg!
1.205 fefe 860: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 861: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 862: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 863:
1.164 fefe 864: 0.12:
865: more contributions from Frank Klemm.
1.165 fefe 866: iconv can now do UCS-2, too.
1.167 fefe 867: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 868: Lots of bug fixes, and several more i386 specific versions of common
869: routines to make them smaller.
1.168 fefe 870: add memmem (a GNU extension that looks useful)
1.170 fefe 871: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 872: add pivot_root syscall, %n for *scanf.
1.169 fefe 873: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 874: add Frank Klemm's optimized md5
1.172 fefe 875: add -Os option to diet (see diet.1).
1.173 fefe 876: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 877: add 32-bit uid/gid syscalls.
1.175 fefe 878: add rand48 (thanks, Johannes Kloos)
1.176 fefe 879: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 880: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
881: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
882: fix gethostent alias list termination. Major oops.
1.178 fefe 883: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 884: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 885: DNS will now properly signal errors and set h_errno.
886: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 887: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
888: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
889: external reference to a symbol that is only in the diet libc. So,
890: when you accidentally link a diet libc compiled object file against
891: glibc, the linker will barf. This will bloat your object files, but
892: you can remove all the references with "strip -R .note" from
893: the binaries in the end (which you should do anyway).
1.182 fefe 894: fix ARM unified syscall (select did not work).
1.183 fefe 895: add getpwent_r ala glibc and replace getpwent
896: do the same for getgrent and getspent
897: remove entlib (new code is smaller)
1.184 fefe 898: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 899: add getpwnam_r and getpwuid_r
1.186 fefe 900: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 901: Olaf muddled with the dynamic linker. It's a clean-room
902: implementation in the sense that it once worked for Olaf in a clean
903: room ;)
1.188 fefe 904: add if_nameindex and if_freenameindex.
905: fixed arm unified syscalls to work with current binutils (; is no
906: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 907: changed all st_[cma]time types to signed long so comparisons against
908: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 909: fixed two bugs regarding ungetc.
910: add getusershell, setusershell, endusershell (for vs_ftpd)
911: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 912: fixed strftime (was completely hosed)
1.192 fefe 913: added real make install target
1.164 fefe 914:
1.115 fefe 915: 0.11:
916: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 917: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 918: add floor, ceil and memchr prototypes.
919: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 920: cleaner errno vs __errno_location handling
921: add placeholder iconv (iconv_open will always return EINVAL)
922: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
923: initialization of getaddrinfo.
1.119 fefe 924: fix vsnprintf %X (printed lower case)
1.120 fefe 925: I wrote a new getopt. It appears to actually work (it is POSIX
926: compliant, it does not sort argv like the GNU version) and is only
927: a little over 300 bytes on x86.
1.121 fefe 928: Guillaume Cottenceau just wrote me that strncat should be even more
929: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 930: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 931: Fix regexec offset return. autoconf now believes that diet libc has
932: POSIX regular expressions.
1.123 fefe 933: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 934: Fix regular expression match for x* when there is no x at all.
1.668 leitner 935: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pr?pper.
1.126 fefe 936: Add %h to vsnprintf.
1.127 fefe 937: Add FAQ.
1.128 fefe 938: Make %h work for signed numbers and add %hh to vsnprintf.
939: initgroups ignored the group argument :-(
940: remove printf references and nested functions from glob.
1.129 fefe 941: added an errno in libpthread that will display a prominent linker
942: warning.
1.131 fefe 943: started getting rid of kernel headers. Big task! :-(
1.130 fefe 944: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 945: Olaf: added a lot of code in libdl (not yet complete), changed the
946: startup code to make it work with his libdl and ld.so (needs still work
947: too)
1.134 fefe 948: __dns_readstartfiles only took the first domain or search path.
949: Thanks, Anthony de Boer
1.133 olaf 950: Olaf: added clone and a new unified_syscall for PowerPC
951: also dynlinker is now available (i386 only at this time)
1.135 fefe 952: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 953: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 954: fixed word delimiters in regex (they looked for space, i.e. "," did
955: not work as delimiter)
1.138 fefe 956: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 957: added mkdtemp.
1.142 fefe 958: Uwe Ohse reported all of the following bugs:
959: ttyname should return 0 if !isatty.
960: realpath returns NULL if "." cannot be opened
961: putenv erroneously accepted (and mishandled) entries without "=".
962: popen returned 255 instead of 127 if /bin/sh could not be run.
963: fgetc did not set the internal EOF indicator on EOF.
964: bsearch contained an assumption about integer arithmetic overflow
965: behavior.
966: system did not set SIGCHLD and thus contained a race.
967: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 968: daemon did not check whether open returns an fd below 3
969: perror did not save errno.
1.144 olaf 970: Olaf: Peter Jones reported some problems with perror; strerror had the
971: same problem.
972: Peter also posted a patch to atexit/exit. With some modifications it is
973: now implemented.
1.145 fefe 974: Unbuffered stdio and ungetc can no longer be disabled. I will try to
975: implement part of it using ELF weak symbols.
1.146 fefe 976: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 977: Added overflow handling for strtoul and strtol.
1.149 fefe 978: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
979: it before falling back to DNS if enabled.
1.150 fefe 980: Added a littie backwards compatibility cruft for gpm (man, do these
981: sources stink!)
1.151 fefe 982: Added openpty.
1.152 fefe 983: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 984: Fix fseek return value.
1.155 fefe 985: Add dirname and basename.
1.156 fefe 986: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 987: Fixed getservent (did not allow _ and - in the aliases).
988: Thanks, Oden Eriksson
1.158 fefe 989: Added a float.h so configure believes we have ANSI header files.
990: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 991: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 992: scanf and printf function implementations
1.160 fefe 993: Imported a few more functions and optimizations from Frank Klemm (he
994: also rewrote dtostr to have more precision)
1.161 olaf 995: Olaf: checked in a new sig* function family (based on rt_sig*).
996: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 997: Made rudimentary iconv that can convert back and forth between
998: iso-8859-1, utf-8 and ucs-4 (for debugging).
999: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 1000:
1.74 fefe 1001: 0.10:
1002: update getpagesize.
1003: add personality.
1.75 fefe 1004: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 1005: add putchar (apparently arm-linux-gcc will substitute printf("\n")
1006: with putchar('\n') behind your back...?!
1.77 fefe 1007: import include/scsi/ from glibc.
1.78 fefe 1008: add iopl.
1.80 fefe 1009: add execl and sigdelset prototypes.
1010: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 1011: add RPC headers (no code yet).
1.82 fefe 1012: add mlockall, munlockall
1.83 fefe 1013: make "diet gcc foo.c" work.
1014: added Sun RPC code and removed as many warnings as possible in a
1015: heroic act of self-mutilation.
1016: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 1017: added getpass. mount from util-linux actually compiles now!
1018: fix the sig*set routines. mount actually works now *bg*
1019: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 1020: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 1021: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 1022: add res_init.
1023: add asprintf (ugh, what an ugly function).
1.89 fefe 1024: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 1025: add ut_name alias to ut_host in struct utmp.
1026: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 1027: add sysinfo, recvmsg, sendmsg.
1.93 fefe 1028: add endmntent, getmntent, setmntent.
1.94 fefe 1029: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 1030: add setenv.
1031: remove __restrict from mntent.h, add __restrict__ removal alias for
1032: older gcc versions in sys/cdefs.h.
1033: add rlim_t, sig_atomic_t declarations.
1034: add sigsetjmp #define for __sigsetjmp (oops).
1035: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 1036: add a gruesome hack to printf floating point to accept %f and kludge
1037: together support for %.2f. Don't look at the code, please!
1.98 fefe 1038: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 1039: imported fix for entlib by Jeff Garzik.
1.100 fefe 1040: add glob implementation from Guillaume Cottenceau (Thanks!!)
1041: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 1042: add REG_ICASE and word start/end handling to my regular expressions.
1043: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 1044: wrap getcwd to comply to man page (the syscall returns the number of
1045: bytes, not the buffer)
1046: add realpath.
1.103 fefe 1047: fix vfprintf.
1.104 fefe 1048: fix *scanf %s zero termination.
1049: add abs, labs, llabs.
1.105 fefe 1050: add <sys/io.h>, ioperm syscall.
1051: add flock to <sys/file.h>
1.106 fefe 1052: fixes to bsearch and the regular expressions.
1.107 fefe 1053: add fake herror.
1.108 fefe 1054: add scandir and alphasort.
1.109 fefe 1055: add killpg
1.110 fefe 1056: implemented a gross hack to make libpthread compile when
1057: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 1058: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 1059: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 1060: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
1061: for sending a patch.
1.114 fefe 1062: add getserv*.
1063: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
1064: "search" from resolv.conf.
1.74 fefe 1065:
1.73 fefe 1066: 0.9:
1.65 fefe 1067: fixed initgroups (oops)
1.66 fefe 1068: Cleanup appending file open for stdio (thanks, James Antill)
1069: imported vfprintf fix from James Antill.
1.67 fefe 1070: add fnmatch
1071: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 1072: Olaf added character classes to *scanf.
1.69 fefe 1073: Put object and library files into a separate directory (bin-$ARCH).
1074: Add "cross" make target to make all architectures.
1075: Add "diet" program and man page.
1.70 fefe 1076: Add getgrnam, getgrgid
1.71 fefe 1077: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 1078: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 1079:
1.64 fefe 1080: 0.8:
1.34 fefe 1081: vsnprintf(0,...) estimated the length of strings with a padding width
1082: incorrectly.
1.35 fefe 1083: new reboot() from Olaf.
1.36 fefe 1084: added prototypes for getsockopt and setsockopt.
1.39 fefe 1085: added experimental sem* and shm*
1.38 fefe 1086: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 1087: added setvbuf (only changes mode, not buffer)
1.41 fefe 1088: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
1089: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 1090: added qsort() and bsearch(). Benchmark on 1000 random ints:
1091: glibc: 679414 cycles qsort and 3352 cycles bsearch
1092: diet libc: 300010 cycles qsort, 553 cycles bsearch
1093: I have no idea why glibc is so slow.
1.43 fefe 1094: added __isnan (references by libm.a from glibc).
1095: added popen() and pclose(). Now the diet libc can link slsh (from
1096: S-Lang!)
1.44 fefe 1097: corrected usleep. It was more of an msleep until now.
1.45 fefe 1098: corrected __dtostr (it looped when trying to format "0.0").
1099: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 1100: added ungetc (does it work?)
1.47 fefe 1101: added inet_aton (yuck!)
1.50 fefe 1102: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 1103: added h_errno and __h_errno_location
1104: added inet_ntoa
1.49 fefe 1105: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 1106: add bcopy, index, rindex macros
1107: add isgraph and isxdigit
1.52 fefe 1108: add strftime (ugh!!!)
1.53 olaf 1109: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 1110: Jeff Garzik contributed a spec file. I put it in contrib and hope
1111: everbody knows what to do with it...
1112: Olaf checked in a ton of libpthread stuff.
1.55 fefe 1113: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 1114: add large file backwards compatibility support (so gzip will run on
1115: kernel 2.2 and 2.0)
1.57 fefe 1116: added shutdown
1.58 fefe 1117: added nice
1118: added pseudo-locale support for is* (they are now weak aliases,
1119: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
1120: overwrite the default is* functions.
1.59 fefe 1121: added liblatin1.a
1.60 fefe 1122: added tzfile implementation (does it work for anyone else?)
1.668 leitner 1123: added syslog(3) (thanks to Rene M?ller!)
1.62 fefe 1124: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
1125: Thanks!
1.63 fefe 1126: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 1127:
1.21 fefe 1128: 0.7.2:
1129: added several prototypes to already implemented functions and
1130: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 1131: added prototypes for process group and dup syscalls. Thanks to
1132: Abraham again. He also contributed an implementation for daemon(),
1133: an ugly BSD hack. I decided to diversify the lib/ directory a
1134: little and now created a libugly/ directory for stuff like system()
1135: and daemon() ;-)
1136: added libstdio and moved all that stdio crap from lib/ there. The
1137: idea is to start separating now what we will separate for shared
1138: libraries anyway.
1.26 fefe 1139: optimized x86 unified-syscall by Olaf.
1.27 fefe 1140: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
1141: limits.h instead)
1142: added remove.c and enough cruft to limits.h to make it compile lzo,
1143: lzop and bzip2.
1.28 fefe 1144: added mktime, asctime_r, asctime and ctime (needed for gzip).
1145: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 1146: format some day (man tzfile, ugh!) :-(
1.29 fefe 1147: added unlink prototype to unistd.h.
1148: added gmtime and gmtime_r.
1.31 fefe 1149: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 1150: removed readdir glibc compatibility cruft.
1.31 fefe 1151: removed stat glibc compatibility cruft.
1.32 fefe 1152: oops, my fread was broken for pipes.
1.33 fefe 1153: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 1154:
1.9 fefe 1155: 0.7.1:
1.11 fefe 1156: optimized away the static arrays from __ltostr and __lltostr.
1157: optimized away the static arrays (and more!) from strtoul and strtoull.
1158: added system (by Olaf).
1.12 fefe 1159: added tolower and toupper
1.13 fefe 1160: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 1161: added clone for mips (by Olaf).
1162: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 1163: added pause for all (by Olaf).
1.17 fefe 1164: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 1165: added isupper and islower.
1166: added putc and putchar as macros.
1.17 fefe 1167: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
1168: insightful discussions and patches I partially used for the last three)
1.18 fefe 1169: added getpriority and setpriority (also by Abraham)
1.19 fefe 1170: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 1171: oi, setjmp and longjmp were broken on other platforms, too!
1.668 leitner 1172: Thanks to S?bastien C?t? for reporting this.
1.9 fefe 1173:
1174: 0.7:
1.6 olaf 1175: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 1176: Initial dynamic loading glue for i386, also by Olaf.
1177: We don't have a dynamic loader yet, so this is not yet usable.
1178: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
1179: vsprintf, writev, all by Olaf.
1.2 fefe 1180: imported readdir fix from Guillaume. Mhh, can the kernel interface
1181: really be this broken?
1.3 fefe 1182: Found a kludgy way to detect whether the kernel includes define struct
1183: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
1184: not work for you, please tell me!
1.4 fefe 1185: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 1186: Fixed stdio line buffering. The code was already there but I forgot
1187: to mark stdio and stdout as line buffered. This should really be
1188: done dynamically using isatty, though.
1.8 fefe 1189: Removed superfluous "if (1)" in execvp.c
1.1 cvs 1190:
1191: 0.6.14:
1192: *scanf did not append the 0 byte for %s.
1193: added creat and changed creat to call open directly instead of open64.
1194: did for fread what 0.6.10 did for fwrite.
1195: repaired buffered stdio a little (line buffering is still not
1196: supported).
1197: [All of these bugs have been reported by Guillaume. Thanks!]
1198: added __pure__ to strchr and strrchr in <string.h>
1199:
1200: 0.6.13:
1201: included COPYING to make clear that the diet libc is covered by the
1202: GNU General Public License (and _not_ the LGPL). That means that
1203: you need to obtain a license from me if you want to use the diet
1204: libc in a proprietary program that you want to distribute.
1205: The x86 unified syscall swapped arguments #4 and #5 and noone
1206: noticed until now! Thanks to Guillaume Cottenceau for reporting
1207: this!
1208: The malloc had a subtle bug with small allocations that could cause
1209: segfault. Guillaume reported it, Olaf fixed it.
1210:
1211: 0.6.12:
1212: added assert, statfs and fstatfs
1213: added include/net/if.h so fget compiles again.
1214:
1215: 0.6.11:
1216: added putenv.
1217:
1218: 0.6.10:
1219: fixed fwrite. It returned the number of bytes written, not the number
1220: of records. Thanks to Albert D. Cahalan for pointing this out.
1221: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
1222: added brk and sbrk. harold@nb.com.sg made me do it.
1223:
1224: 0.6.9:
1225: fixed execvp not to return on ENOENT
1226: did for {open|read|close|seek|tell}dir what I did for stat before.
1227: The glibc compatibility part is currently non-functional.
1228: fixed white space handling in sscanf " (" would not match " (".
1229: fixed printf to accept 'l' flag.
1230: fixed getpwuid (ignored last line)
1231:
1232: 0.6.8:
1233: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
1234: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
1235: added strlcpy and strlcat from OpenBSD.
1236: added stat64, fstat64 and lstat64.
1237: added endian.h and made ending of strlen.c endianness-aware
1238: added string routines size tweak to dietfeatures.h. Most of the
1239: string routines have been unrolled. This is up to three times as
1240: fast but creates up to three times larger code. Now you can disable
1241: the unrolling.
1242: added sendfile.
1243: I also added pread. It works on x86 and sparc but not on ppc and mips.
1244: I have no idea what's going on. strace disagrees with the kernel.
1245: Can anyone help? I asked the Linux kernel mailing list for help, too.
1246: added a few aliases of the type __libc_open for open. nm on
1247: libpthreads.so indicates that we will need them.
1248:
1249: 0.6.7:
1250: the sources now compile without warnings with -Wall.
1251: printf now prints "(null)" when %s is passed NULL. This can be
1252: removed with WANT_NULL_PRINTF in dietfeatures.h
1253: added vfprintf, execl, ttyname.
1254: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
1255: __dietfstat so they can use the normal kernel struct stat.
1256: stat, lstat and fstat are now C wrappers that convert to the glibc
1257: struct stat. So we can avoid that overhead for programs that use
1258: dietlibc headers.
1259:
1260: 0.6.6:
1261: changed the Makefiles so you can now set CFLAGS on the command line
1262: added memccmp (analogous to memccpy) and strncmp.
1263: Olaf fixed another bug in the sparc unified syscall.
1264: Paul Clifford contributed a C version of his strlen.S that is much
1265: more efficient than the previous strlen on all platforms! It also
1266: looks like technology from Roswell. ;-}
1267: added a "real" stdio. Well, almost. Please contribute!
1268: added dietfeatures.h so you can remove features you don't need.
1269: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
1270: stdio now works with simple programs and minigzip from libz.
1271: stdio uses some major trickery to avoid linking the stdio, stderr and
1272: stdout (and reserving space for them) when they are not used.
1273:
1274: 0.6.5:
1275: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
1276: most of them bugs in the new header files, but also missing sigset
1277: functions.
1278: Paul Clifford contributed an assembly strlen.S for ARM and fixed
1279: several bugs.
1280: Fixed ppc/setjmp and mips/pipe.
1281: Olaf contributed a new sparc unified syscall.
1282:
1283: 0.6.4:
1284: declared is* static inline in getservent.
1285: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
1286: changed strlen to return 0 when passed NULL.
1287: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
1288: Scientist who actually implemented this without access to a MIPS
1289: box, just from reading the architecture manual. And it worked out
1290: of the box.
1291: started a set of system includes, mainly so that I can use lcc and
1292: my alpha-linux cross compiler (which is unable to cross-compile
1293: glibc). diet libc can now be compiled without any include files
1294: from a normal libc. The includes do declare more than diet libc
1295: currently delivers and they are still far from complete for real
1296: applications.
1297: I will only add assembly versions that are smaller _and_ faster than
1298: the C version. Larger routines are only accepted if they are called
1299: very often and are substantially faster.
1300: added i386 assembly strchr, which is smaller and faster than the old
1301: version. It is, however, larger than the version contributed by
1302: proton (thanks, anyway).
1303: added i386 strlen (31% faster, 14% smaller)
1304: "make t" will now create a map file called "mapfile".
1305:
1306: 0.6.3:
1307: added sys_errlist, strerror and perror
1308: added isblank
1309: added atol
1310:
1311: 0.6.2:
1312: mmap for ARM didn't compile. Thanks, Paul!
1313:
1314: 0.6.1:
1315: split mmap into the architecture specific subdirectories.
1316: getenv now copes with environ==NULL, thanks Paul Clifford.
1317: Paul also contributed a smaller ARM startup code.
1318:
1319: 0.6:
1.668 leitner 1320: strcat returned the wrong result. Thanks, Dietz Pr?pper.
1.1 cvs 1321: strtod now understands a negative exponent (oops, thanks Bertram Barth)
1322: Port to arm-linux-gnu, but on the Netwinder I use for testing the
1323: __dtostr does not work (I have no idea why!)
1324: The MIPS port now uses (much smaller) non-PIC code. That means that
1325: the applications you link against diet libc also have to be compiled
1326: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
1.668 leitner 1327: Thanks to Ralf B?chle for helping me with this!
1.1 cvs 1328: I made subdirectories for the architectures and use VPATH to override
1329: VPATH so that make finds the source file automatically. That should
1330: simplify the sources greatly.
1331: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
1332: ARM and MIPS now also have setjmp and longjmp
1333: "compile" and "load" are now make targets. Use them for djb programs.
1334: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1335: Again, contributed from Olaf. Great work!
1336:
1337: 0.5.12:
1338: printf also does signed numbers.
1339: If you don't use atexit, dietlibc now does not link exit, only _exit.
1340: *printf now correctly returns the number of bytes written.
1341: Olaf contributed experimental sscanf and vsscanf implementations.
1342: If passed NULL as buffer, snprintf will not write anything but still
1343: return the number of bytes it would have written.
1344: Initial MIPS port! (Oh, the agony!)
1345: No setjmp and longjmp support yet! Please contribute!
1346: I even implemented unified syscalls for MIPS. Still, MIPS code is
1347: almost twice the size of SPARC code. If anyone knows why: please
1348: tell me!
1349:
1350: 0.5.11:
1351: I implemented new unified syscalls for x86, sparc and ppc, this time based
1352: on .s files and not .c files, and I moved the syscalls into
1353: subdirectores to clean the dietlibc sources up a little.
1354: A binary consisting of printf("%s is %d\n","olaf",23) is now
1355: 2864 bytes on sparc
1356: 2488 bytes on intel
1357: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1358: to make a few more applications work.
1359: Olaf Dreesen also implemented some unified syscall stuff for x86.
1360: He discovered that with our unified syscall interface it actually
1361: costs <10 bytes total to make all system calls thread safe!
1362: I implemented atexit() (can register up to 4 callbacks).
1363: I implemented strtod and __dtostr (the opposite). Now we can add
1364: floating point support to vsnprintf and sscanf!
1365:
1366: 0.5.10:
1367: I actually saw that I can not only merge the errno handling code of
1368: the system calls on x86, I can also merge the rest (including the
1369: arguments) except for setting the system call number. All those
1370: system calls are now just a jump to a unified system call handler.
1371: I got rid of x86openclose again. The savings are substantial:
1372: chown from embutils went from 7664 to 7184 bytes!
1373: If I'd move the system call wrappers to assembly language, I could
1374: even reduce the alignment (does not matter since it's just a jump
1375: anyway) and get rid of the "ret" behind each jump (one byte per
1376: system call!)
1377:
1378: 0.5.9:
1379: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1380: fixed strdup
1381: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1382: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1383: (no signed integers, only strings and unsigned integers (but
1384: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1385: that code must be wonderful, I don't understand it at all *bg*)
1386: Olaf's printf does understand padding like in "%08d" and "%8d" and
1387: automatically pads pointers with '0'.
1388: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1389: Thanks to proton for inspiration on this.
1390: The new x86 start code also does not reference exit any more, thus saving
1391: 64 bytes for executables that don't call exit explicitly.
1392: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1393: Moved errno and environ to start.S, saving no byte binary size but
1394: speeding up compilation and slightly shortening dietlibc.a ;-)
1395: For x86: joined open and close into one assembler file, sharing the
1396: errno handling. This is a feasibility test and it actually saves a
1397: few bytes. I think I will reimplement the _syscall[1-6] macros on
1398: all platforms now to share the errno handling code for them.
1399:
1400: 0.5.8:
1401: fixed strchr to be able to look for 0.
1402:
1403: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1404: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1405: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1406: contributed by Olaf Dreesen)
1407:
1408: added execvp, getcwd
1409:
1410: fixed __xmknod
1411:
1412: Note: can it be that the ftw interface really is so broken that I
1413: cannot implement it without having to implement some searching data
1414: structure? I included an experimental ftw implementation that will
1415: not follow symlinks.
1416:
1417: 0.5.7:
1418: oops, if_nametoindex was broken!
1419:
1420: 0.5.6:
1421: ported to ppc-linux.
1422: fixed i386 sigsetjmp (I mistyped the function name)
1423: included sigjmp.c
1424:
1425: 0.5.5:
1426: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1427: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1428: I fixed it now.
1429: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1430: fixed readdir to use getdents and not the intel inline asm
1431:
1432: 0.5.4:
1433: ported to sparclinux (sparc32 only). Beware: does not work yet.
1434: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1435:
1436: 0.5.3:
1437: added tcsetattr and getenv to compile e3
1438:
1439: 0.5.2:
1440: added vhangup, tcgetattr, isatty and memcmp for fgetty
1441: (http://www.fefe.de/fgetty/)
1442: added localtime from uC-libc.
1443:
1444: 0.5.1:
1445: stat and friends actually work now. Yuck! Another case of
1446: translation between kernel and userland. Why can't the kernel
1447: people and the libc people simply agree on a standard?
1448: removed many unnecessary includes to speed up compilation.
1449: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1450: inlined socketcall to reduce code size.
1451: "load" and "compile" are examples for djb code.
1452:
1453: 0.5:
1454: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1455: each object file is now treated with "strip -x -R .note -R .comment"
1456: split each system call into a separate object file
1457: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1458:
1459: 0.4.1:
1460: oops, the strchr implementation was wrong. Thanks Jens Laas!
1461:
1462: 0.4:
1463: copied opendir and friends from uC-libc.
1464: added getservent and getservby* in gerservent.c
1465:
1466: 0.3:
1467: remove readdir system call
1468: added getdents system call
1469: added getpwnam/getpwuid implementation in getpwnam.c
1470: added a few string functions (in str*.c)
