Annotation of dietlibc/CHANGES, revision 1.732
1.697 leitner 1: 0.34:
2: move stpcpy from libcompat to lib as it is now part of POSIX (Enrico Scholz)
1.698 leitner 3: add linux/seccomp.h linux/prctl.h linux/audit.h linux/elf-em.h linux/filter.h
1.699 leitner 4: SECURITY: make sure all assembler files mark the stack non-executable so
5: the kernel can map the stack of the whole program as non-executable
1.700 leitner 6: support compiling with clang (no cross compiling yet, and the resulting
7: binary code is significantly larger than with gcc)
8: implement experimental C11 threads
1.701 leitner 9: fix fgets (Andreas Förster)
1.702 leitner 10: add eventfd, inotify_init1, epoll_init1, accept4, recvmmsg, sendmmsg
11: add dup3, fanotify_init, fanotify_mark, signalfd4, timerfd_settime
1.703 leitner 12: add timerfd_gettime, setns, memfd_create, getrandom, syncfs
1.704 leitner 13: add preadv, pwritev
1.705 leitner 14: add getcontext, setcontext, makecontext, swapcontext (i386 and x86_64 only for now)
1.706 leitner 15: add implementation of hsearch and friends
1.707 leitner 16: add strverscmp (like GNU version but without special treatment for leading zeros)
1.708 leitner 17: fix cuserid
1.709 leitner 18: SECURITY: fix integer overflow in scandir/scandir64 if your selector
19: leaves more than 1 billion filenames
1.710 leitner 20: fix memory leaks in out of memory error paths in regcomp and librpc
21: udp and tcp server code (found by the llvm static analyzer)

26: fix dn_expand argument signedness
1.716 leitner 27: add explicit_bzero, timingsafe_bcmp and timingsafe_memcmp (OpenBSD APIs useful for crypto)
1.717 leitner 28: i386 switched from mmap to mmap2. glibc has been doing this for ages,
29: and we now follow suit (without fallback to mmap), because
30: seccomp-filter can't inspect mmap arguments, so this helps security.
1.718 leitner 31: plumbing to get preliminary PIE support for x86_64

1.732 ! leitner 49: powerpc fixes (Gerrit Pape, Christian Seiler)
1.697 leitner 50:
1.673 leitner 51: 0.33:
1.674 leitner 52: first stab at getting TLS to work in actual threads
53: use fs: to find current thread on x86_64
1.675 leitner 54: add fallocate, posix_fallocate
1.676 leitner 55: work around Ubuntu who added -fstack-protector to their gcc, which
56: added stack protector code to the function from the dietlibc startup
57: code that sets up the registers and segments used by the stack
58: protector mechanism.

64: update sys/stat.h to include nsec and enlarge dev_t
1.682 leitner 65: add WANT_VALGRIND_SUPPORT in dietfeatures.h. When #defined, the
66: startup code will check if the program is running under valgrind,
67: and if it is, the SIMD optimized string routines will switch back to
68: a slower version that does not generate valgrind false positives.
1.683 leitner 69: add WANT_LLMNR in dietfeatures.h. Now you can do "ping windowsbox"
70: and it works if that box runs win7 and trusts the LAN; the down side
71: is that LLMNR does not like the .local prefix, so DNS does zeroconf
72: lookup for unqualified names now, too.
1.684 leitner 73: add WANT_GNU_STARTUP_BLOAT in dietfeatures.h to support
74: program_invocation_short_name and program_invocation_name

87: add WANT_HOSTS_GIVEUP_EARLY in dietfeatures.h
1.691 leitner 88: various build fixes, add sys/atomic.h and the __CAS function
1.692 leitner 89: redo nice with get/setpriority as glibc does (Thierry Vignaud)

1.307 fefe 666: cleanups from Florian LaRoche
1.281 fefe 667:
1.264 fefe 668: 0.17:
1.265 fefe 669: fix several bugs in getservent_r
1.266 fefe 670: Gunnar Ritter reported the following:
671: moved tcgetpgrp and tcsetpgrp to unistd.h
672: adjusted lstat->lstat64 #define to make it work with function pointers
673: move __dietlibc__ #define from features.h to diet
1.267 fefe 674: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
675: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 676: Thomas also sent me profiling support (so far only on x86, but
677: profiling/PORTING describes what needs to be done for other
678: architectures)!
1.272 fefe 679: add contrib/dprof.c, also from Thomas.
1.269 fefe 680: Andreas Krennmair sent a patch to add the BSD regex interface to
681: libcompat
1.271 fefe 682: Andre noticed that __dtostr never sets first to false. Oops!
1.274 fefe 683: Andre has provided a largely untested patch that seems to fix the problem.
1.275 fefe 684: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 685: abort did not flush all stdio streams
1.277 fefe 686: fix some nasty regular expression bugs
687: write a stupid malloc checker (contrib/debug-realloc.c) to help me
688: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 689: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 690: fix DNS domain search
1.280 fefe 691: i386 memccpy exchanged esi and edi :-( I should do more checks before
692: accepting external code...
1.264 fefe 693:
1.244 fefe 694: 0.16:
695: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 696: Andre found two very embarassing bugs in my four lines of md5 glue.
697: I need to get more sleep.
1.247 fefe 698: Thanks Ogrisegg found that ptrace does not work as documented and
699: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 700: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
701: fix ptrace.h for S/390 and ARM
702: provide a PORTING document so we don't lose track of which file need
703: to be touched to port the diet libc to a new platform.
1.249 fefe 704: remove a few warnings
705: provide a prototype for usleep.
1.250 fefe 706: make __dtostr work on ARM by using long instead of long long.
707: Idea by Dirk Engling.
1.251 fefe 708: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 709: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 710: Kurt Garloff sent in patches to
711: fix struct termios on non-x86 architectures
1.254 fefe 712: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
713: create libcompat.a (and move daemon to it)
1.255 fefe 714: add getdelim and getline
715: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 716: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 717: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 718: Hans Lermen fixed i386/getenv.S
1.259 fefe 719: diet -Os no longer discards -fpic and -fno-pic
1.260 fefe 720: fix i386 rand/random to use correct RAND_MAX (thanks, Jaroslav
721: Macodiseas)
1.261 fefe 722: sys/ipc.h now includes sys/types.h
1.262 olaf 723: Olaf: started to make the sparc64 port
1.263 fefe 724: scandir should not sort if compar() is NULL (reported by Andrea Marrosu)
1.244 fefe 725:
1.224 fefe 726: 0.15:
1.225 fefe 727: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 728: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 729: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
730: thread-safe!
1.228 fefe 731: remove vfork and add alarm to dynamic syscalls.
732: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 733: The MD5 code generated unaligned accesses when passed an unaligned
734: pointer on little endian ARM and MIPS.
735: MIPS unified syscall didn't compile anymore.
736: Put up new mipsel target to cross compile for little endian mips.
737: The mips target will again explicitly set endianness to big endian.
738: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 739: Duh, when we removed return0, we broke tzset when the time zone parser
740: was disabled. Uwe Ohse noticed this. Thanks!
741: Fix gethostbyname to match host names case insensitively in /etc/hosts.
742: Oops, this was reported 6 weeks ago but I overlooked the email.
743: Thanks, Denis Rachal!
1.231 fefe 744: vsnprintf's zero termination was broken.
1.233 fefe 745: Uwe Ohse found a few more bugs:
746: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
747: does it correctly.
748: Make inet_aton use strtoul instead of strtol
749: fdopen would close the file descriptor if it could not malloc the
750: buffer.
751: strftime updates.
752: Make _FILE_OFFSET_BITS includes -Wundef clean
753: Andre found a typo in endian.h for big endian mips
1.234 fefe 754: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 755: strstr(whatever,"") returned NULL, not whatever. Found by a new test
756: suite entry for strstr that I wrote.
1.245 fefe 757: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 758: add <asm/sigcontext.h> for profiling support.
759: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 760: an i386 assembler getenv implementation (roughly half the size)
761: add grantpt, ptsname, unlockpt
1.236 fefe 762: add a getenv test suite entry.
1.238 fefe 763: Andre contributed an ARM assembler md5 implementation and he fixed mmap
764: on ARM.
765: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 766: getservent_r did not parse lines without aliases. Thanks, Jaroslav
767: Macodiseas!
1.240 fefe 768: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 769: removed annoying -Wconversion gcc switch
1.242 fefe 770: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 771: Kurt Garloff sent these diffs:
772: add fdatasync (and make it a pthread cancellation point)
773: numerous alpha issues, like using .quad instead of .long for
774: offsets, change strip to -strip in Makefile (so a failing strip does
775: not abort the make), try to be more friendly to the gcc 2.96 that
776: SuSE 7.1 AXP ships with.
1.224 fefe 777:
1.209 fefe 778: 0.14:
1.224 fefe 779: fix brk again (missing __brk, trivial oversight)
1.210 fefe 780: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
781: Thomas Ogrisegg!
1.211 fefe 782: Thomas also contributed a PA-RISC port including testandset, so
783: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 784: made the fake locale more believable.
785: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 786: moved _exit into the unified syscall on x86.
1.214 fefe 787: Uwe Ohse found many more bugs:
788: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
789: liblatin1 was more or less completely broken if you gave it chars as
790: arguments, not ints (signedness). execvp had a buffer overflow in
791: case a PATH element exceeded PATH_MAX, but it's not a security
792: problem since setuid programs need to set their path to some known
793: value anyway.
1.219 fefe 794: hasmntopt did not work with foo=bar style options
1.217 fefe 795: Uwe also improved ftw's stack usage.
1.214 fefe 796: Put movl instead of popl rationale in comment in i386/unified.S since
797: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 798: I discovered __attribute__((malloc)) and started using it. For gcc 3,
799: it improves the optimizer when functions return malloced pointers.
1.216 fefe 800: Steven Rostedt pointed out that my setvbuf was broken with regard to
801: size==0 and sent a patch to fix it.
1.218 fefe 802: Thomas Ogrisegg made setenv smaller.
1.220 olaf 803: Olaf: implemented the parisc clone and an atomic testandset, modified the
804: libpthread to respect the parisc UPgrowing stack. still non functional,
805: because the unified syscall uses errno :(
1.221 fefe 806: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 807: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
808: don't write anything which was no longer the case. It also
809: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 810: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 811:
1.193 fefe 812: 0.13:
1.194 fefe 813: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 814: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 815: Olaf: port to S/390!
1.463 leitner 816: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 817: res_query did not initialize last
1.199 fefe 818: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 819: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 820: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 821: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 822: rewrote __dtostr (it also has one more argument now)
1.205 fefe 823: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 824: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
825: fix strncat for the case where n == 0 (security implications?)
826: fix bsearch (it didn't find the very last element in the array, same
827: bug in both the C and the i386 assembly version).
1.205 fefe 828: fixed FNM_PATHNAME in fnmatch
1.204 fefe 829: fix brk (the syscall was documented incorrectly in the Linux man page)
830: Thanks, Thomas Ogrisegg!
1.205 fefe 831: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 832: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 833: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 834:
1.164 fefe 835: 0.12:
836: more contributions from Frank Klemm.
1.165 fefe 837: iconv can now do UCS-2, too.
1.167 fefe 838: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 839: Lots of bug fixes, and several more i386 specific versions of common
840: routines to make them smaller.
1.168 fefe 841: add memmem (a GNU extension that looks useful)
1.170 fefe 842: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 843: add pivot_root syscall, %n for *scanf.
1.169 fefe 844: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 845: add Frank Klemm's optimized md5
1.172 fefe 846: add -Os option to diet (see diet.1).
1.173 fefe 847: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 848: add 32-bit uid/gid syscalls.
1.175 fefe 849: add rand48 (thanks, Johannes Kloos)
1.176 fefe 850: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 851: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
852: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
853: fix gethostent alias list termination. Major oops.
1.178 fefe 854: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 855: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 856: DNS will now properly signal errors and set h_errno.
857: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 858: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
859: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
860: external reference to a symbol that is only in the diet libc. So,
861: when you accidentally link a diet libc compiled object file against
862: glibc, the linker will barf. This will bloat your object files, but
863: you can remove all the references with "strip -R .note" from
864: the binaries in the end (which you should do anyway).
1.182 fefe 865: fix ARM unified syscall (select did not work).
1.183 fefe 866: add getpwent_r ala glibc and replace getpwent
867: do the same for getgrent and getspent
868: remove entlib (new code is smaller)
1.184 fefe 869: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 870: add getpwnam_r and getpwuid_r
1.186 fefe 871: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 872: Olaf muddled with the dynamic linker. It's a clean-room
873: implementation in the sense that it once worked for Olaf in a clean
874: room ;)
1.188 fefe 875: add if_nameindex and if_freenameindex.
876: fixed arm unified syscalls to work with current binutils (; is no
877: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 878: changed all st_[cma]time types to signed long so comparisons against
879: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 880: fixed two bugs regarding ungetc.
881: add getusershell, setusershell, endusershell (for vs_ftpd)
882: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 883: fixed strftime (was completely hosed)
1.192 fefe 884: added real make install target
1.164 fefe 885:
1.115 fefe 886: 0.11:
887: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 888: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 889: add floor, ceil and memchr prototypes.
890: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 891: cleaner errno vs __errno_location handling
892: add placeholder iconv (iconv_open will always return EINVAL)
893: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
894: initialization of getaddrinfo.
1.119 fefe 895: fix vsnprintf %X (printed lower case)
1.120 fefe 896: I wrote a new getopt. It appears to actually work (it is POSIX
897: compliant, it does not sort argv like the GNU version) and is only
898: a little over 300 bytes on x86.
1.121 fefe 899: Guillaume Cottenceau just wrote me that strncat should be even more
900: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 901: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 902: Fix regexec offset return. autoconf now believes that diet libc has
903: POSIX regular expressions.
1.123 fefe 904: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 905: Fix regular expression match for x* when there is no x at all.
1.668 leitner 906: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pr?pper.
1.126 fefe 907: Add %h to vsnprintf.
1.127 fefe 908: Add FAQ.
1.128 fefe 909: Make %h work for signed numbers and add %hh to vsnprintf.
910: initgroups ignored the group argument :-(
911: remove printf references and nested functions from glob.
1.129 fefe 912: added an errno in libpthread that will display a prominent linker
913: warning.
1.131 fefe 914: started getting rid of kernel headers. Big task! :-(
1.130 fefe 915: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 916: Olaf: added a lot of code in libdl (not yet complete), changed the
917: startup code to make it work with his libdl and ld.so (needs still work
918: too)
1.134 fefe 919: __dns_readstartfiles only took the first domain or search path.
920: Thanks, Anthony de Boer
1.133 olaf 921: Olaf: added clone and a new unified_syscall for PowerPC
922: also dynlinker is now available (i386 only at this time)
1.135 fefe 923: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 924: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 925: fixed word delimiters in regex (they looked for space, i.e. "," did
926: not work as delimiter)
1.138 fefe 927: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 928: added mkdtemp.
1.142 fefe 929: Uwe Ohse reported all of the following bugs:
930: ttyname should return 0 if !isatty.
931: realpath returns NULL if "." cannot be opened
932: putenv erroneously accepted (and mishandled) entries without "=".
933: popen returned 255 instead of 127 if /bin/sh could not be run.
934: fgetc did not set the internal EOF indicator on EOF.
935: bsearch contained an assumption about integer arithmetic overflow
936: behavior.
937: system did not set SIGCHLD and thus contained a race.
938: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 939: daemon did not check whether open returns an fd below 3
940: perror did not save errno.
1.144 olaf 941: Olaf: Peter Jones reported some problems with perror; strerror had the
942: same problem.
943: Peter also posted a patch to atexit/exit. With some modifications it is
944: now implemented.
1.145 fefe 945: Unbuffered stdio and ungetc can no longer be disabled. I will try to
946: implement part of it using ELF weak symbols.
1.146 fefe 947: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 948: Added overflow handling for strtoul and strtol.
1.149 fefe 949: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
950: it before falling back to DNS if enabled.
1.150 fefe 951: Added a littie backwards compatibility cruft for gpm (man, do these
952: sources stink!)
1.151 fefe 953: Added openpty.
1.152 fefe 954: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 955: Fix fseek return value.
1.155 fefe 956: Add dirname and basename.
1.156 fefe 957: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 958: Fixed getservent (did not allow _ and - in the aliases).
959: Thanks, Oden Eriksson
1.158 fefe 960: Added a float.h so configure believes we have ANSI header files.
961: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 962: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 963: scanf and printf function implementations
1.160 fefe 964: Imported a few more functions and optimizations from Frank Klemm (he
965: also rewrote dtostr to have more precision)
1.161 olaf 966: Olaf: checked in a new sig* function family (based on rt_sig*).
967: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 968: Made rudimentary iconv that can convert back and forth between
969: iso-8859-1, utf-8 and ucs-4 (for debugging).
970: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 971:
1.74 fefe 972: 0.10:
973: update getpagesize.
974: add personality.
1.75 fefe 975: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 976: add putchar (apparently arm-linux-gcc will substitute printf("\n")
977: with putchar('\n') behind your back...?!
1.77 fefe 978: import include/scsi/ from glibc.
1.78 fefe 979: add iopl.
1.80 fefe 980: add execl and sigdelset prototypes.
981: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 982: add RPC headers (no code yet).
1.82 fefe 983: add mlockall, munlockall
1.83 fefe 984: make "diet gcc foo.c" work.
985: added Sun RPC code and removed as many warnings as possible in a
986: heroic act of self-mutilation.
987: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 988: added getpass. mount from util-linux actually compiles now!
989: fix the sig*set routines. mount actually works now *bg*
990: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 991: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 992: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 993: add res_init.
994: add asprintf (ugh, what an ugly function).
1.89 fefe 995: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 996: add ut_name alias to ut_host in struct utmp.
997: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 998: add sysinfo, recvmsg, sendmsg.
1.93 fefe 999: add endmntent, getmntent, setmntent.
1.94 fefe 1000: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 1001: add setenv.
1002: remove __restrict from mntent.h, add __restrict__ removal alias for
1003: older gcc versions in sys/cdefs.h.
1004: add rlim_t, sig_atomic_t declarations.
1005: add sigsetjmp #define for __sigsetjmp (oops).
1006: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 1007: add a gruesome hack to printf floating point to accept %f and kludge
1008: together support for %.2f. Don't look at the code, please!
1.98 fefe 1009: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 1010: imported fix for entlib by Jeff Garzik.
1.100 fefe 1011: add glob implementation from Guillaume Cottenceau (Thanks!!)
1012: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 1013: add REG_ICASE and word start/end handling to my regular expressions.
1014: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 1015: wrap getcwd to comply to man page (the syscall returns the number of
1016: bytes, not the buffer)
1017: add realpath.
1.103 fefe 1018: fix vfprintf.
1.104 fefe 1019: fix *scanf %s zero termination.
1020: add abs, labs, llabs.
1.105 fefe 1021: add <sys/io.h>, ioperm syscall.
1022: add flock to <sys/file.h>
1.106 fefe 1023: fixes to bsearch and the regular expressions.
1.107 fefe 1024: add fake herror.
1.108 fefe 1025: add scandir and alphasort.
1.109 fefe 1026: add killpg
1.110 fefe 1027: implemented a gross hack to make libpthread compile when
1028: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 1029: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 1030: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 1031: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
1032: for sending a patch.
1.114 fefe 1033: add getserv*.
1034: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
1035: "search" from resolv.conf.
1.74 fefe 1036:
1.73 fefe 1037: 0.9:
1.65 fefe 1038: fixed initgroups (oops)
1.66 fefe 1039: Cleanup appending file open for stdio (thanks, James Antill)
1040: imported vfprintf fix from James Antill.
1.67 fefe 1041: add fnmatch
1042: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 1043: Olaf added character classes to *scanf.
1.69 fefe 1044: Put object and library files into a separate directory (bin-$ARCH).
1045: Add "cross" make target to make all architectures.
1046: Add "diet" program and man page.
1.70 fefe 1047: Add getgrnam, getgrgid
1.71 fefe 1048: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 1049: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 1050:
1.64 fefe 1051: 0.8:
1.34 fefe 1052: vsnprintf(0,...) estimated the length of strings with a padding width
1053: incorrectly.
1.35 fefe 1054: new reboot() from Olaf.
1.36 fefe 1055: added prototypes for getsockopt and setsockopt.
1.39 fefe 1056: added experimental sem* and shm*
1.38 fefe 1057: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 1058: added setvbuf (only changes mode, not buffer)
1.41 fefe 1059: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
1060: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 1061: added qsort() and bsearch(). Benchmark on 1000 random ints:
1062: glibc: 679414 cycles qsort and 3352 cycles bsearch
1063: diet libc: 300010 cycles qsort, 553 cycles bsearch
1064: I have no idea why glibc is so slow.
1.43 fefe 1065: added __isnan (references by libm.a from glibc).
1066: added popen() and pclose(). Now the diet libc can link slsh (from
1067: S-Lang!)
1.44 fefe 1068: corrected usleep. It was more of an msleep until now.
1.45 fefe 1069: corrected __dtostr (it looped when trying to format "0.0").
1070: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 1071: added ungetc (does it work?)
1.47 fefe 1072: added inet_aton (yuck!)
1.50 fefe 1073: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 1074: added h_errno and __h_errno_location
1075: added inet_ntoa
1.49 fefe 1076: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 1077: add bcopy, index, rindex macros
1078: add isgraph and isxdigit
1.52 fefe 1079: add strftime (ugh!!!)
1.53 olaf 1080: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 1081: Jeff Garzik contributed a spec file. I put it in contrib and hope
1082: everbody knows what to do with it...
1083: Olaf checked in a ton of libpthread stuff.
1.55 fefe 1084: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 1085: add large file backwards compatibility support (so gzip will run on
1086: kernel 2.2 and 2.0)
1.57 fefe 1087: added shutdown
1.58 fefe 1088: added nice
1089: added pseudo-locale support for is* (they are now weak aliases,
1090: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
1091: overwrite the default is* functions.
1.59 fefe 1092: added liblatin1.a
1.60 fefe 1093: added tzfile implementation (does it work for anyone else?)
1.668 leitner 1094: added syslog(3) (thanks to Rene M?ller!)
1.62 fefe 1095: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
1096: Thanks!
1.63 fefe 1097: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 1098:
1.21 fefe 1099: 0.7.2:
1100: added several prototypes to already implemented functions and
1101: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 1102: added prototypes for process group and dup syscalls. Thanks to
1103: Abraham again. He also contributed an implementation for daemon(),
1104: an ugly BSD hack. I decided to diversify the lib/ directory a
1105: little and now created a libugly/ directory for stuff like system()
1106: and daemon() ;-)
1107: added libstdio and moved all that stdio crap from lib/ there. The
1108: idea is to start separating now what we will separate for shared
1109: libraries anyway.
1.26 fefe 1110: optimized x86 unified-syscall by Olaf.
1.27 fefe 1111: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
1112: limits.h instead)
1113: added remove.c and enough cruft to limits.h to make it compile lzo,
1114: lzop and bzip2.
1.28 fefe 1115: added mktime, asctime_r, asctime and ctime (needed for gzip).
1116: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 1117: format some day (man tzfile, ugh!) :-(
1.29 fefe 1118: added unlink prototype to unistd.h.
1119: added gmtime and gmtime_r.
1.31 fefe 1120: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 1121: removed readdir glibc compatibility cruft.
1.31 fefe 1122: removed stat glibc compatibility cruft.
1.32 fefe 1123: oops, my fread was broken for pipes.
1.33 fefe 1124: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 1125:
1.9 fefe 1126: 0.7.1:
1.11 fefe 1127: optimized away the static arrays from __ltostr and __lltostr.
1128: optimized away the static arrays (and more!) from strtoul and strtoull.
1129: added system (by Olaf).
1.12 fefe 1130: added tolower and toupper
1.13 fefe 1131: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 1132: added clone for mips (by Olaf).
1133: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 1134: added pause for all (by Olaf).
1.17 fefe 1135: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 1136: added isupper and islower.
1137: added putc and putchar as macros.
1.17 fefe 1138: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
1139: insightful discussions and patches I partially used for the last three)
1.18 fefe 1140: added getpriority and setpriority (also by Abraham)
1.19 fefe 1141: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 1142: oi, setjmp and longjmp were broken on other platforms, too!
1.668 leitner 1143: Thanks to S?bastien C?t? for reporting this.
1.9 fefe 1144:
1145: 0.7:
1.6 olaf 1146: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 1147: Initial dynamic loading glue for i386, also by Olaf.
1148: We don't have a dynamic loader yet, so this is not yet usable.
1149: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
1150: vsprintf, writev, all by Olaf.
1.2 fefe 1151: imported readdir fix from Guillaume. Mhh, can the kernel interface
1152: really be this broken?
1.3 fefe 1153: Found a kludgy way to detect whether the kernel includes define struct
1154: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
1155: not work for you, please tell me!
1.4 fefe 1156: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 1157: Fixed stdio line buffering. The code was already there but I forgot
1158: to mark stdio and stdout as line buffered. This should really be
1159: done dynamically using isatty, though.
1.8 fefe 1160: Removed superfluous "if (1)" in execvp.c
1.1 cvs 1161:
1162: 0.6.14:
1163: *scanf did not append the 0 byte for %s.
1164: added creat and changed creat to call open directly instead of open64.
1165: did for fread what 0.6.10 did for fwrite.
1166: repaired buffered stdio a little (line buffering is still not
1167: supported).
1168: [All of these bugs have been reported by Guillaume. Thanks!]
1169: added __pure__ to strchr and strrchr in <string.h>
1170:
1171: 0.6.13:
1172: included COPYING to make clear that the diet libc is covered by the
1173: GNU General Public License (and _not_ the LGPL). That means that
1174: you need to obtain a license from me if you want to use the diet
1175: libc in a proprietary program that you want to distribute.
1176: The x86 unified syscall swapped arguments #4 and #5 and noone
1177: noticed until now! Thanks to Guillaume Cottenceau for reporting
1178: this!
1179: The malloc had a subtle bug with small allocations that could cause
1180: segfault. Guillaume reported it, Olaf fixed it.
1181:
1182: 0.6.12:
1183: added assert, statfs and fstatfs
1184: added include/net/if.h so fget compiles again.
1185:
1186: 0.6.11:
1187: added putenv.
1188:
1189: 0.6.10:
1190: fixed fwrite. It returned the number of bytes written, not the number
1191: of records. Thanks to Albert D. Cahalan for pointing this out.
1192: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
1193: added brk and sbrk. harold@nb.com.sg made me do it.
1194:
1195: 0.6.9:
1196: fixed execvp not to return on ENOENT
1197: did for {open|read|close|seek|tell}dir what I did for stat before.
1198: The glibc compatibility part is currently non-functional.
1199: fixed white space handling in sscanf " (" would not match " (".
1200: fixed printf to accept 'l' flag.
1201: fixed getpwuid (ignored last line)
1202:
1203: 0.6.8:
1204: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
1205: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
1206: added strlcpy and strlcat from OpenBSD.
1207: added stat64, fstat64 and lstat64.
1208: added endian.h and made ending of strlen.c endianness-aware
1209: added string routines size tweak to dietfeatures.h. Most of the
1210: string routines have been unrolled. This is up to three times as
1211: fast but creates up to three times larger code. Now you can disable
1212: the unrolling.
1213: added sendfile.
1214: I also added pread. It works on x86 and sparc but not on ppc and mips.
1215: I have no idea what's going on. strace disagrees with the kernel.
1216: Can anyone help? I asked the Linux kernel mailing list for help, too.
1217: added a few aliases of the type __libc_open for open. nm on
1218: libpthreads.so indicates that we will need them.
1219:
1220: 0.6.7:
1221: the sources now compile without warnings with -Wall.
1222: printf now prints "(null)" when %s is passed NULL. This can be
1223: removed with WANT_NULL_PRINTF in dietfeatures.h
1224: added vfprintf, execl, ttyname.
1225: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
1226: __dietfstat so they can use the normal kernel struct stat.
1227: stat, lstat and fstat are now C wrappers that convert to the glibc
1228: struct stat. So we can avoid that overhead for programs that use
1229: dietlibc headers.
1230:
1231: 0.6.6:
1232: changed the Makefiles so you can now set CFLAGS on the command line
1233: added memccmp (analogous to memccpy) and strncmp.
1234: Olaf fixed another bug in the sparc unified syscall.
1235: Paul Clifford contributed a C version of his strlen.S that is much
1236: more efficient than the previous strlen on all platforms! It also
1237: looks like technology from Roswell. ;-}
1238: added a "real" stdio. Well, almost. Please contribute!
1239: added dietfeatures.h so you can remove features you don't need.
1240: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
1241: stdio now works with simple programs and minigzip from libz.
1242: stdio uses some major trickery to avoid linking the stdio, stderr and
1243: stdout (and reserving space for them) when they are not used.
1244:
1245: 0.6.5:
1246: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
1247: most of them bugs in the new header files, but also missing sigset
1248: functions.
1249: Paul Clifford contributed an assembly strlen.S for ARM and fixed
1250: several bugs.
1251: Fixed ppc/setjmp and mips/pipe.
1252: Olaf contributed a new sparc unified syscall.
1253:
1254: 0.6.4:
1255: declared is* static inline in getservent.
1256: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
1257: changed strlen to return 0 when passed NULL.
1258: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
1259: Scientist who actually implemented this without access to a MIPS
1260: box, just from reading the architecture manual. And it worked out
1261: of the box.
1262: started a set of system includes, mainly so that I can use lcc and
1263: my alpha-linux cross compiler (which is unable to cross-compile
1264: glibc). diet libc can now be compiled without any include files
1265: from a normal libc. The includes do declare more than diet libc
1266: currently delivers and they are still far from complete for real
1267: applications.
1268: I will only add assembly versions that are smaller _and_ faster than
1269: the C version. Larger routines are only accepted if they are called
1270: very often and are substantially faster.
1271: added i386 assembly strchr, which is smaller and faster than the old
1272: version. It is, however, larger than the version contributed by
1273: proton (thanks, anyway).
1274: added i386 strlen (31% faster, 14% smaller)
1275: "make t" will now create a map file called "mapfile".
1276:
1277: 0.6.3:
1278: added sys_errlist, strerror and perror
1279: added isblank
1280: added atol
1281:
1282: 0.6.2:
1283: mmap for ARM didn't compile. Thanks, Paul!
1284:
1285: 0.6.1:
1286: split mmap into the architecture specific subdirectories.
1287: getenv now copes with environ==NULL, thanks Paul Clifford.
1288: Paul also contributed a smaller ARM startup code.
1289:
1290: 0.6:
1.668 leitner 1291: strcat returned the wrong result. Thanks, Dietz Pr?pper.
1.1 cvs 1292: strtod now understands a negative exponent (oops, thanks Bertram Barth)
1293: Port to arm-linux-gnu, but on the Netwinder I use for testing the
1294: __dtostr does not work (I have no idea why!)
1295: The MIPS port now uses (much smaller) non-PIC code. That means that
1296: the applications you link against diet libc also have to be compiled
1297: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
1.668 leitner 1298: Thanks to Ralf B?chle for helping me with this!
1.1 cvs 1299: I made subdirectories for the architectures and use VPATH to override
1300: VPATH so that make finds the source file automatically. That should
1301: simplify the sources greatly.
1302: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
1303: ARM and MIPS now also have setjmp and longjmp
1304: "compile" and "load" are now make targets. Use them for djb programs.
1305: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1306: Again, contributed from Olaf. Great work!
1307:
1308: 0.5.12:
1309: printf also does signed numbers.
1310: If you don't use atexit, dietlibc now does not link exit, only _exit.
1311: *printf now correctly returns the number of bytes written.
1312: Olaf contributed experimental sscanf and vsscanf implementations.
1313: If passed NULL as buffer, snprintf will not write anything but still
1314: return the number of bytes it would have written.
1315: Initial MIPS port! (Oh, the agony!)
1316: No setjmp and longjmp support yet! Please contribute!
1317: I even implemented unified syscalls for MIPS. Still, MIPS code is
1318: almost twice the size of SPARC code. If anyone knows why: please
1319: tell me!
1320:
1321: 0.5.11:
1322: I implemented new unified syscalls for x86, sparc and ppc, this time based
1323: on .s files and not .c files, and I moved the syscalls into
1324: subdirectores to clean the dietlibc sources up a little.
1325: A binary consisting of printf("%s is %d\n","olaf",23) is now
1326: 2864 bytes on sparc
1327: 2488 bytes on intel
1328: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1329: to make a few more applications work.
1330: Olaf Dreesen also implemented some unified syscall stuff for x86.
1331: He discovered that with our unified syscall interface it actually
1332: costs <10 bytes total to make all system calls thread safe!
1333: I implemented atexit() (can register up to 4 callbacks).
1334: I implemented strtod and __dtostr (the opposite). Now we can add
1335: floating point support to vsnprintf and sscanf!
1336:
1337: 0.5.10:
1338: I actually saw that I can not only merge the errno handling code of
1339: the system calls on x86, I can also merge the rest (including the
1340: arguments) except for setting the system call number. All those
1341: system calls are now just a jump to a unified system call handler.
1342: I got rid of x86openclose again. The savings are substantial:
1343: chown from embutils went from 7664 to 7184 bytes!
1344: If I'd move the system call wrappers to assembly language, I could
1345: even reduce the alignment (does not matter since it's just a jump
1346: anyway) and get rid of the "ret" behind each jump (one byte per
1347: system call!)
1348:
1349: 0.5.9:
1350: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1351: fixed strdup
1352: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1353: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1354: (no signed integers, only strings and unsigned integers (but
1355: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1356: that code must be wonderful, I don't understand it at all *bg*)
1357: Olaf's printf does understand padding like in "%08d" and "%8d" and
1358: automatically pads pointers with '0'.
1359: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1360: Thanks to proton for inspiration on this.
1361: The new x86 start code also does not reference exit any more, thus saving
1362: 64 bytes for executables that don't call exit explicitly.
1363: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1364: Moved errno and environ to start.S, saving no byte binary size but
1365: speeding up compilation and slightly shortening dietlibc.a ;-)
1366: For x86: joined open and close into one assembler file, sharing the
1367: errno handling. This is a feasibility test and it actually saves a
1368: few bytes. I think I will reimplement the _syscall[1-6] macros on
1369: all platforms now to share the errno handling code for them.
1370:
1371: 0.5.8:
1372: fixed strchr to be able to look for 0.
1373:
1374: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1375: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1376: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1377: contributed by Olaf Dreesen)
1378:
1379: added execvp, getcwd
1380:
1381: fixed __xmknod
1382:
1383: Note: can it be that the ftw interface really is so broken that I
1384: cannot implement it without having to implement some searching data
1385: structure? I included an experimental ftw implementation that will
1386: not follow symlinks.
1387:
1388: 0.5.7:
1389: oops, if_nametoindex was broken!
1390:
1391: 0.5.6:
1392: ported to ppc-linux.
1393: fixed i386 sigsetjmp (I mistyped the function name)
1394: included sigjmp.c
1395:
1396: 0.5.5:
1397: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1398: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1399: I fixed it now.
1400: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1401: fixed readdir to use getdents and not the intel inline asm
1402:
1403: 0.5.4:
1404: ported to sparclinux (sparc32 only). Beware: does not work yet.
1405: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1406:
1407: 0.5.3:
1408: added tcsetattr and getenv to compile e3
1409:
1410: 0.5.2:
1411: added vhangup, tcgetattr, isatty and memcmp for fgetty
1412: (http://www.fefe.de/fgetty/)
1413: added localtime from uC-libc.
1414:
1415: 0.5.1:
1416: stat and friends actually work now. Yuck! Another case of
1417: translation between kernel and userland. Why can't the kernel
1418: people and the libc people simply agree on a standard?
1419: removed many unnecessary includes to speed up compilation.
1420: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1421: inlined socketcall to reduce code size.
1422: "load" and "compile" are examples for djb code.
1423:
1424: 0.5:
1425: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1426: each object file is now treated with "strip -x -R .note -R .comment"
1427: split each system call into a separate object file
1428: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1429:
1430: 0.4.1:
1431: oops, the strchr implementation was wrong. Thanks Jens Laas!
1432:
1433: 0.4:
1434: copied opendir and friends from uC-libc.
1435: added getservent and getservby* in gerservent.c
1436:
1437: 0.3:
1438: remove readdir system call
1439: added getdents system call
1440: added getpwnam/getpwuid implementation in getpwnam.c
1441: added a few string functions (in str*.c)
