1.352 fefe 15: fix unified x86_64 unified syscall 64-bit return value issue (Gwenole)
1.353 fefe 16: the getdents64 emulation was broken and repairing it opened a can of
17: worms. So I ripped it out. I also changed the readdir64 emulation
18: to work if there is no getdents64.
1.354 fefe 19: fix ia64 start.S (Thanks to Volker Birk for an account on his ia64 box)
1.355 fefe 20: many ia64 fixes (waitpid, nice, fork, vfork, time, utime ...)
1.356 fefe 21: More fixes from Gwenole (printf %p only printed the last 32 bits, I
22: botched the getdents64 #ifdefs, we violated the x86_64 ABI)
1.357 fefe 23: change signal() to do as glibc does

1.360 fefe 27: the new x86 syscall numbers exceed 255, breaking our %al optimization
28: I worked around it with conditional assembly in cpp macros. Ugh.
1.361 fefe 29: more MIPS fixes (the stoned MIPS ABI for restartable syscalls expects
30: the instruction before the syscall to be a load immediate)
31: fix fread() from a pipe (oops, tried to lseek)
1.362 fefe 32: #define _POSIX_VDISABLE in termios.h (Laurent Bercot)
1.363 fefe 33: two *printf fixes (Gernot Tenchio)

42: use -G 8 on MIPS to reduce code size (Johannes Stezenbach)
1.328 fefe 43: add munlock (Jens Låås)
1.330 fefe 44: argh, atexit fell victim to bit rot (or maybe Olaf)
1.331 fefe 45: add WANT_INET_ADDR_DNS to make gethostbyname not look up IP numbers
46: but use them to fill in the struct hostent directly.
1.332 olaf 47: signal is now a correct signal (Olaf)
1.333 fefe 48: read optimizer cflags for diet -Os gcc from ~/.diet/gcc, overriding
49: the built-in defaults.
1.334 fefe 50: add file "SECURITY". I will document design tradeoffs that have
51: security implications there.
1.335 fefe 52: fixed regex LINEEND condition
1.336 fefe 53: add .size directive to i386 syscalls
1.337 fefe 54: shove a few more bytes off the i386 socket calls
1.339 fefe 55: setjmp, longjmp and clone for x86_64 are now implemented but not tested (Olaf)

68: current gcc cvs makes __thread a keyword (Eric Troan)
1.316 fefe 69: be more strict regarding hostile DNS packets (me)
1.312 fefe 70: fix ia64 compile problems (Gerrit Pape)
1.311 fefe 71: make killpg a function and not a macro (broke bash 2.05b)
1.313 fefe 72: fix ia64 start code and unified syscall (me)
1.314 fefe 73: add sparc/strlen.S from Thomas Ogrisegg
74: add more space to ARM __jmp_buf in setjmp.h (Andre)
1.315 fefe 75: fix libcompat/syscall.S (did't compile on arm)
1.316 fefe 76: add integer overflow fix in xdr_array after bugtraq advisory (me)

1.282 fefe 82: add stpcpy (from Thomas Ogrisegg)
83: check in mktime fix (from Luc Van Oostenryck)
1.283 fefe 84: add libm2.s from contrib to i386 (oops, how long has it been sitting
85: there?)
1.284 fefe 86: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.285 fefe 87: Michal Ludvig ported the diet libc to the x86_64 architecture (the
88: upcoming AMD Hammer chips!). You can't even buy the chips yet and
89: the diet libc already supports it! Amazing ;-)
90: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 91: Andre sent a patch to add ARM profiling. He says it does not work

127: adjusted lstat->lstat64 #define to make it work with function pointers
128: move __dietlibc__ #define from features.h to diet
1.267 fefe 129: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
130: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 131: Thomas also sent me profiling support (so far only on x86, but
132: profiling/PORTING describes what needs to be done for other
133: architectures)!
1.272 fefe 134: add contrib/dprof.c, also from Thomas.
1.269 fefe 135: Andreas Krennmair sent a patch to add the BSD regex interface to
136: libcompat
1.271 fefe 137: Andre noticed that __dtostr never sets first to false. Oops!
1.274 fefe 138: Andre has provided a largely untested patch that seems to fix the problem.
1.275 fefe 139: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 140: abort did not flush all stdio streams
1.277 fefe 141: fix some nasty regular expression bugs
142: write a stupid malloc checker (contrib/debug-realloc.c) to help me
143: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 144: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 145: fix DNS domain search
1.280 fefe 146: i386 memccpy exchanged esi and edi :-( I should do more checks before
147: accepting external code...
1.264 fefe 148:
1.244 fefe 149: 0.16:
150: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 151: Andre found two very embarassing bugs in my four lines of md5 glue.
152: I need to get more sleep.
1.247 fefe 153: Thanks Ogrisegg found that ptrace does not work as documented and
154: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 155: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
156: fix ptrace.h for S/390 and ARM
157: provide a PORTING document so we don't lose track of which file need
158: to be touched to port the diet libc to a new platform.
1.249 fefe 159: remove a few warnings
160: provide a prototype for usleep.
1.250 fefe 161: make __dtostr work on ARM by using long instead of long long.
162: Idea by Dirk Engling.
1.251 fefe 163: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 164: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 165: Kurt Garloff sent in patches to
166: fix struct termios on non-x86 architectures
1.254 fefe 167: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
168: create libcompat.a (and move daemon to it)
1.255 fefe 169: add getdelim and getline
170: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 171: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 172: Olaf: fixed *scanf familie. It hadn't wored with "long long".

1.244 fefe 180:
1.224 fefe 181: 0.15:
1.225 fefe 182: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 183: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 184: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
185: thread-safe!
1.228 fefe 186: remove vfork and add alarm to dynamic syscalls.
187: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 188: The MD5 code generated unaligned accesses when passed an unaligned
189: pointer on little endian ARM and MIPS.
190: MIPS unified syscall didn't compile anymore.
191: Put up new mipsel target to cross compile for little endian mips.
192: The mips target will again explicitly set endianness to big endian.
193: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 194: Duh, when we removed return0, we broke tzset when the time zone parser
195: was disabled. Uwe Ohse noticed this. Thanks!
196: Fix gethostbyname to match host names case insensitively in /etc/hosts.
197: Oops, this was reported 6 weeks ago but I overlooked the email.
198: Thanks, Denis Rachal!
1.231 fefe 199: vsnprintf's zero termination was broken.
1.233 fefe 200: Uwe Ohse found a few more bugs:
201: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
202: does it correctly.
203: Make inet_aton use strtoul instead of strtol
204: fdopen would close the file descriptor if it could not malloc the
205: buffer.
206: strftime updates.
207: Make _FILE_OFFSET_BITS includes -Wundef clean
208: Andre found a typo in endian.h for big endian mips
1.234 fefe 209: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 210: strstr(whatever,"") returned NULL, not whatever. Found by a new test
211: suite entry for strstr that I wrote.
1.245 fefe 212: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 213: add <asm/sigcontext.h> for profiling support.
214: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 215: an i386 assembler getenv implementation (roughly half the size)
216: add grantpt, ptsname, unlockpt
1.236 fefe 217: add a getenv test suite entry.
1.238 fefe 218: Andre contributed an ARM assembler md5 implementation and he fixed mmap
219: on ARM.
220: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 221: getservent_r did not parse lines without aliases. Thanks, Jaroslav
222: Macodiseas!
1.240 fefe 223: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 224: removed annoying -Wconversion gcc switch
1.242 fefe 225: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 226: Kurt Garloff sent these diffs:
227: add fdatasync (and make it a pthread cancellation point)
228: numerous alpha issues, like using .quad instead of .long for
229: offsets, change strip to -strip in Makefile (so a failing strip does
230: not abort the make), try to be more friendly to the gcc 2.96 that
231: SuSE 7.1 AXP ships with.
1.224 fefe 232:
1.209 fefe 233: 0.14:
1.224 fefe 234: fix brk again (missing __brk, trivial oversight)
1.210 fefe 235: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
236: Thomas Ogrisegg!
1.211 fefe 237: Thomas also contributed a PA-RISC port including testandset, so
238: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 239: made the fake locale more believable.
240: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 241: moved _exit into the unified syscall on x86.
1.214 fefe 242: Uwe Ohse found many more bugs:
243: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
244: liblatin1 was more or less completely broken if you gave it chars as
245: arguments, not ints (signedness). execvp had a buffer overflow in
246: case a PATH element exceeded PATH_MAX, but it's not a security
247: problem since setuid programs need to set their path to some known
248: value anyway.
1.219 fefe 249: hasmntopt did not work with foo=bar style options
1.217 fefe 250: Uwe also improved ftw's stack usage.
1.214 fefe 251: Put movl instead of popl rationale in comment in i386/unified.S since
252: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 253: I discovered __attribute__((malloc)) and started using it. For gcc 3,
254: it improves the optimizer when functions return malloced pointers.
1.216 fefe 255: Steven Rostedt pointed out that my setvbuf was broken with regard to
256: size==0 and sent a patch to fix it.
1.218 fefe 257: Thomas Ogrisegg made setenv smaller.
1.220 olaf 258: Olaf: implemented the parisc clone and an atomic testandset, modified the
259: libpthread to respect the parisc UPgrowing stack. still non functional,
260: because the unified syscall uses errno :(
1.221 fefe 261: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 262: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
263: don't write anything which was no longer the case. It also
264: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 265: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 266:
1.193 fefe 267: 0.13:
1.194 fefe 268: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 269: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 270: Olaf: port to S/390!
1.196 leitner 271: me: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 272: res_query did not initialize last
1.199 fefe 273: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 274: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 275: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 276: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 277: rewrote __dtostr (it also has one more argument now)
1.205 fefe 278: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 279: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
280: fix strncat for the case where n == 0 (security implications?)
281: fix bsearch (it didn't find the very last element in the array, same
282: bug in both the C and the i386 assembly version).
1.205 fefe 283: fixed FNM_PATHNAME in fnmatch
1.204 fefe 284: fix brk (the syscall was documented incorrectly in the Linux man page)
285: Thanks, Thomas Ogrisegg!
1.205 fefe 286: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 287: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 288: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 289:
1.164 fefe 290: 0.12:
291: more contributions from Frank Klemm.
1.165 fefe 292: iconv can now do UCS-2, too.
1.167 fefe 293: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 294: Lots of bug fixes, and several more i386 specific versions of common
295: routines to make them smaller.
1.168 fefe 296: add memmem (a GNU extension that looks useful)
1.170 fefe 297: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 298: add pivot_root syscall, %n for *scanf.
1.169 fefe 299: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 300: add Frank Klemm's optimized md5
1.172 fefe 301: add -Os option to diet (see diet.1).
1.173 fefe 302: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 303: add 32-bit uid/gid syscalls.
1.175 fefe 304: add rand48 (thanks, Johannes Kloos)
1.176 fefe 305: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 306: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
307: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
308: fix gethostent alias list termination. Major oops.
1.178 fefe 309: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 310: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 311: DNS will now properly signal errors and set h_errno.
312: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 313: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
314: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
315: external reference to a symbol that is only in the diet libc. So,
316: when you accidentally link a diet libc compiled object file against
317: glibc, the linker will barf. This will bloat your object files, but
318: you can remove all the references with "strip -R .note" from
319: the binaries in the end (which you should do anyway).
1.182 fefe 320: fix ARM unified syscall (select did not work).
1.183 fefe 321: add getpwent_r ala glibc and replace getpwent
322: do the same for getgrent and getspent
323: remove entlib (new code is smaller)
1.184 fefe 324: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 325: add getpwnam_r and getpwuid_r
1.186 fefe 326: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 327: Olaf muddled with the dynamic linker. It's a clean-room
328: implementation in the sense that it once worked for Olaf in a clean
329: room ;)
1.188 fefe 330: add if_nameindex and if_freenameindex.
331: fixed arm unified syscalls to work with current binutils (; is no
332: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 333: changed all st_[cma]time types to signed long so comparisons against
334: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 335: fixed two bugs regarding ungetc.
336: add getusershell, setusershell, endusershell (for vs_ftpd)
337: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 338: fixed strftime (was completely hosed)
1.192 fefe 339: added real make install target
1.164 fefe 340:
1.115 fefe 341: 0.11:
342: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 343: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 344: add floor, ceil and memchr prototypes.
345: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 346: cleaner errno vs __errno_location handling
347: add placeholder iconv (iconv_open will always return EINVAL)
348: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
349: initialization of getaddrinfo.
1.119 fefe 350: fix vsnprintf %X (printed lower case)
1.120 fefe 351: I wrote a new getopt. It appears to actually work (it is POSIX
352: compliant, it does not sort argv like the GNU version) and is only
353: a little over 300 bytes on x86.
1.121 fefe 354: Guillaume Cottenceau just wrote me that strncat should be even more
355: broken than it already is: it should append n bytes AND THEN \0!
356: I wonder how many programmers have produces off-by-one errors here...
1.122 fefe 357: Fix regexec offset return. autoconf now believes that diet libc has
358: POSIX regular expressions.
1.123 fefe 359: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 360: Fix regular expression match for x* when there is no x at all.
1.125 fefe 361: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 362: Add %h to vsnprintf.
1.127 fefe 363: Add FAQ.
1.128 fefe 364: Make %h work for signed numbers and add %hh to vsnprintf.
365: initgroups ignored the group argument :-(
366: remove printf references and nested functions from glob.
1.129 fefe 367: added an errno in libpthread that will display a prominent linker
368: warning.
1.131 fefe 369: started getting rid of kernel headers. Big task! :-(
1.130 fefe 370: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 371: Olaf: added a lot of code in libdl (not yet complete), changed the
372: startup code to make it work with his libdl and ld.so (needs still work
373: too)
1.134 fefe 374: __dns_readstartfiles only took the first domain or search path.
375: Thanks, Anthony de Boer
1.133 olaf 376: Olaf: added clone and a new unified_syscall for PowerPC
377: also dynlinker is now available (i386 only at this time)
1.135 fefe 378: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 379: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 380: fixed word delimiters in regex (they looked for space, i.e. "," did
381: not work as delimiter)
1.138 fefe 382: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 383: added mkdtemp.
1.142 fefe 384: Uwe Ohse reported all of the following bugs:
385: ttyname should return 0 if !isatty.
386: realpath returns NULL if "." cannot be opened
387: putenv erroneously accepted (and mishandled) entries without "=".
388: popen returned 255 instead of 127 if /bin/sh could not be run.
389: fgetc did not set the internal EOF indicator on EOF.
390: bsearch contained an assumption about integer arithmetic overflow
391: behavior.
392: system did not set SIGCHLD and thus contained a race.
393: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 394: daemon did not check whether open returns an fd below 3
395: perror did not save errno.
1.144 olaf 396: Olaf: Peter Jones reported some problems with perror; strerror had the
397: same problem.
398: Peter also posted a patch to atexit/exit. With some modifications it is
399: now implemented.
1.145 fefe 400: Unbuffered stdio and ungetc can no longer be disabled. I will try to
401: implement part of it using ELF weak symbols.
1.146 fefe 402: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 403: Added overflow handling for strtoul and strtol.
1.149 fefe 404: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
405: it before falling back to DNS if enabled.
1.150 fefe 406: Added a littie backwards compatibility cruft for gpm (man, do these
407: sources stink!)
1.151 fefe 408: Added openpty.
1.152 fefe 409: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 410: Fix fseek return value.
1.155 fefe 411: Add dirname and basename.
1.156 fefe 412: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 413: Fixed getservent (did not allow _ and - in the aliases).
414: Thanks, Oden Eriksson
1.158 fefe 415: Added a float.h so configure believes we have ANSI header files.
416: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 417: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 418: scanf and printf function implementations
1.160 fefe 419: Imported a few more functions and optimizations from Frank Klemm (he
420: also rewrote dtostr to have more precision)
1.161 olaf 421: Olaf: checked in a new sig* function family (based on rt_sig*).
422: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 423: Made rudimentary iconv that can convert back and forth between
424: iso-8859-1, utf-8 and ucs-4 (for debugging).
425: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 426:
1.74 fefe 427: 0.10:
428: update getpagesize.
429: add personality.
1.75 fefe 430: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 431: add putchar (apparently arm-linux-gcc will substitute printf("\n")
432: with putchar('\n') behind your back...?!
1.77 fefe 433: import include/scsi/ from glibc.
1.78 fefe 434: add iopl.
1.80 fefe 435: add execl and sigdelset prototypes.
436: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 437: add RPC headers (no code yet).
1.82 fefe 438: add mlockall, munlockall
1.83 fefe 439: make "diet gcc foo.c" work.
440: added Sun RPC code and removed as many warnings as possible in a
441: heroic act of self-mutilation.
442: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 443: added getpass. mount from util-linux actually compiles now!
444: fix the sig*set routines. mount actually works now *bg*
445: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 446: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 447: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 448: add res_init.
449: add asprintf (ugh, what an ugly function).
1.89 fefe 450: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 451: add ut_name alias to ut_host in struct utmp.
452: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 453: add sysinfo, recvmsg, sendmsg.
1.93 fefe 454: add endmntent, getmntent, setmntent.
1.94 fefe 455: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 456: add setenv.
457: remove __restrict from mntent.h, add __restrict__ removal alias for
458: older gcc versions in sys/cdefs.h.
459: add rlim_t, sig_atomic_t declarations.
460: add sigsetjmp #define for __sigsetjmp (oops).
461: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 462: add a gruesome hack to printf floating point to accept %f and kludge
463: together support for %.2f. Don't look at the code, please!
1.98 fefe 464: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 465: imported fix for entlib by Jeff Garzik.
1.100 fefe 466: add glob implementation from Guillaume Cottenceau (Thanks!!)
467: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 468: add REG_ICASE and word start/end handling to my regular expressions.
469: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 470: wrap getcwd to comply to man page (the syscall returns the number of
471: bytes, not the buffer)
472: add realpath.
1.103 fefe 473: fix vfprintf.
1.104 fefe 474: fix *scanf %s zero termination.
475: add abs, labs, llabs.
1.105 fefe 476: add <sys/io.h>, ioperm syscall.
477: add flock to <sys/file.h>
1.106 fefe 478: fixes to bsearch and the regular expressions.
1.107 fefe 479: add fake herror.
1.108 fefe 480: add scandir and alphasort.
1.109 fefe 481: add killpg
1.110 fefe 482: implemented a gross hack to make libpthread compile when
483: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 484: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 485: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 486: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
487: for sending a patch.
1.114 fefe 488: add getserv*.
489: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
490: "search" from resolv.conf.
1.74 fefe 491:
1.73 fefe 492: 0.9:
1.65 fefe 493: fixed initgroups (oops)
1.66 fefe 494: Cleanup appending file open for stdio (thanks, James Antill)
495: imported vfprintf fix from James Antill.
1.67 fefe 496: add fnmatch
497: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 498: Olaf added character classes to *scanf.
1.69 fefe 499: Put object and library files into a separate directory (bin-$ARCH).
500: Add "cross" make target to make all architectures.
501: Add "diet" program and man page.
1.70 fefe 502: Add getgrnam, getgrgid
1.71 fefe 503: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 504: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 505:
1.64 fefe 506: 0.8:
1.34 fefe 507: vsnprintf(0,...) estimated the length of strings with a padding width
508: incorrectly.
1.35 fefe 509: new reboot() from Olaf.
1.36 fefe 510: added prototypes for getsockopt and setsockopt.
1.39 fefe 511: added experimental sem* and shm*
1.38 fefe 512: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 513: added setvbuf (only changes mode, not buffer)
1.41 fefe 514: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
515: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 516: added qsort() and bsearch(). Benchmark on 1000 random ints:
517: glibc: 679414 cycles qsort and 3352 cycles bsearch
518: diet libc: 300010 cycles qsort, 553 cycles bsearch
519: I have no idea why glibc is so slow.
1.43 fefe 520: added __isnan (references by libm.a from glibc).
521: added popen() and pclose(). Now the diet libc can link slsh (from
522: S-Lang!)
1.44 fefe 523: corrected usleep. It was more of an msleep until now.
1.45 fefe 524: corrected __dtostr (it looped when trying to format "0.0").
525: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 526: added ungetc (does it work?)
1.47 fefe 527: added inet_aton (yuck!)
1.50 fefe 528: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 529: added h_errno and __h_errno_location
530: added inet_ntoa
1.49 fefe 531: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 532: add bcopy, index, rindex macros
533: add isgraph and isxdigit
1.52 fefe 534: add strftime (ugh!!!)
1.53 olaf 535: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 536: Jeff Garzik contributed a spec file. I put it in contrib and hope
537: everbody knows what to do with it...
538: Olaf checked in a ton of libpthread stuff.
1.55 fefe 539: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 540: add large file backwards compatibility support (so gzip will run on
541: kernel 2.2 and 2.0)
1.57 fefe 542: added shutdown
1.58 fefe 543: added nice
544: added pseudo-locale support for is* (they are now weak aliases,
545: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
546: overwrite the default is* functions.
1.59 fefe 547: added liblatin1.a
1.60 fefe 548: added tzfile implementation (does it work for anyone else?)
1.61 fefe 549: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 550: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
551: Thanks!
1.63 fefe 552: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 553:
1.21 fefe 554: 0.7.2:
555: added several prototypes to already implemented functions and
556: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 557: added prototypes for process group and dup syscalls. Thanks to
558: Abraham again. He also contributed an implementation for daemon(),
559: an ugly BSD hack. I decided to diversify the lib/ directory a
560: little and now created a libugly/ directory for stuff like system()
561: and daemon() ;-)
562: added libstdio and moved all that stdio crap from lib/ there. The
563: idea is to start separating now what we will separate for shared
564: libraries anyway.
1.26 fefe 565: optimized x86 unified-syscall by Olaf.
1.27 fefe 566: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
567: limits.h instead)
568: added remove.c and enough cruft to limits.h to make it compile lzo,
569: lzop and bzip2.
1.28 fefe 570: added mktime, asctime_r, asctime and ctime (needed for gzip).
571: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 572: format some day (man tzfile, ugh!) :-(
1.29 fefe 573: added unlink prototype to unistd.h.
574: added gmtime and gmtime_r.
1.31 fefe 575: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 576: removed readdir glibc compatibility cruft.
1.31 fefe 577: removed stat glibc compatibility cruft.
1.32 fefe 578: oops, my fread was broken for pipes.
1.33 fefe 579: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 580:
1.9 fefe 581: 0.7.1:
1.11 fefe 582: optimized away the static arrays from __ltostr and __lltostr.
583: optimized away the static arrays (and more!) from strtoul and strtoull.
584: added system (by Olaf).
1.12 fefe 585: added tolower and toupper
1.13 fefe 586: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 587: added clone for mips (by Olaf).
588: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 589: added pause for all (by Olaf).
1.17 fefe 590: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 591: added isupper and islower.
592: added putc and putchar as macros.
1.17 fefe 593: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
594: insightful discussions and patches I partially used for the last three)
1.18 fefe 595: added getpriority and setpriority (also by Abraham)
1.19 fefe 596: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 597: oi, setjmp and longjmp were broken on other platforms, too!
598: Thanks to Sébastien Côté for reporting this.
1.9 fefe 599:
600: 0.7:
1.6 olaf 601: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 602: Initial dynamic loading glue for i386, also by Olaf.
603: We don't have a dynamic loader yet, so this is not yet usable.
604: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
605: vsprintf, writev, all by Olaf.
1.2 fefe 606: imported readdir fix from Guillaume. Mhh, can the kernel interface
607: really be this broken?
1.3 fefe 608: Found a kludgy way to detect whether the kernel includes define struct
609: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
610: not work for you, please tell me!
1.4 fefe 611: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 612: Fixed stdio line buffering. The code was already there but I forgot
613: to mark stdio and stdout as line buffered. This should really be
614: done dynamically using isatty, though.
1.8 fefe 615: Removed superfluous "if (1)" in execvp.c
1.1 cvs 616:
617: 0.6.14:
618: *scanf did not append the 0 byte for %s.
619: added creat and changed creat to call open directly instead of open64.
620: did for fread what 0.6.10 did for fwrite.
621: repaired buffered stdio a little (line buffering is still not
622: supported).
623: [All of these bugs have been reported by Guillaume. Thanks!]
624: added __pure__ to strchr and strrchr in <string.h>
625:
626: 0.6.13:
627: included COPYING to make clear that the diet libc is covered by the
628: GNU General Public License (and _not_ the LGPL). That means that
629: you need to obtain a license from me if you want to use the diet
630: libc in a proprietary program that you want to distribute.
631: The x86 unified syscall swapped arguments #4 and #5 and noone
632: noticed until now! Thanks to Guillaume Cottenceau for reporting
633: this!
634: The malloc had a subtle bug with small allocations that could cause
635: segfault. Guillaume reported it, Olaf fixed it.
636:
637: 0.6.12:
638: added assert, statfs and fstatfs
639: added include/net/if.h so fget compiles again.
640:
641: 0.6.11:
642: added putenv.
643:
644: 0.6.10:
645: fixed fwrite. It returned the number of bytes written, not the number
646: of records. Thanks to Albert D. Cahalan for pointing this out.
647: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
648: added brk and sbrk. harold@nb.com.sg made me do it.
649:
650: 0.6.9:
651: fixed execvp not to return on ENOENT
652: did for {open|read|close|seek|tell}dir what I did for stat before.
653: The glibc compatibility part is currently non-functional.
654: fixed white space handling in sscanf " (" would not match " (".
655: fixed printf to accept 'l' flag.
656: fixed getpwuid (ignored last line)
657:
658: 0.6.8:
659: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
660: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
661: added strlcpy and strlcat from OpenBSD.
662: added stat64, fstat64 and lstat64.
663: added endian.h and made ending of strlen.c endianness-aware
664: added string routines size tweak to dietfeatures.h. Most of the
665: string routines have been unrolled. This is up to three times as
666: fast but creates up to three times larger code. Now you can disable
667: the unrolling.
668: added sendfile.
669: I also added pread. It works on x86 and sparc but not on ppc and mips.
670: I have no idea what's going on. strace disagrees with the kernel.
671: Can anyone help? I asked the Linux kernel mailing list for help, too.
672: added a few aliases of the type __libc_open for open. nm on
673: libpthreads.so indicates that we will need them.
674:
675: 0.6.7:
676: the sources now compile without warnings with -Wall.
677: printf now prints "(null)" when %s is passed NULL. This can be
678: removed with WANT_NULL_PRINTF in dietfeatures.h
679: added vfprintf, execl, ttyname.
680: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
681: __dietfstat so they can use the normal kernel struct stat.
682: stat, lstat and fstat are now C wrappers that convert to the glibc
683: struct stat. So we can avoid that overhead for programs that use
684: dietlibc headers.
685:
686: 0.6.6:
687: changed the Makefiles so you can now set CFLAGS on the command line
688: added memccmp (analogous to memccpy) and strncmp.
689: Olaf fixed another bug in the sparc unified syscall.
690: Paul Clifford contributed a C version of his strlen.S that is much
691: more efficient than the previous strlen on all platforms! It also
692: looks like technology from Roswell. ;-}
693: added a "real" stdio. Well, almost. Please contribute!
694: added dietfeatures.h so you can remove features you don't need.
695: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
696: stdio now works with simple programs and minigzip from libz.
697: stdio uses some major trickery to avoid linking the stdio, stderr and
698: stdout (and reserving space for them) when they are not used.
699:
700: 0.6.5:
701: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
702: most of them bugs in the new header files, but also missing sigset
703: functions.
704: Paul Clifford contributed an assembly strlen.S for ARM and fixed
705: several bugs.
706: Fixed ppc/setjmp and mips/pipe.
707: Olaf contributed a new sparc unified syscall.
708:
709: 0.6.4:
710: declared is* static inline in getservent.
711: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
712: changed strlen to return 0 when passed NULL.
713: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
714: Scientist who actually implemented this without access to a MIPS
715: box, just from reading the architecture manual. And it worked out
716: of the box.
717: started a set of system includes, mainly so that I can use lcc and
718: my alpha-linux cross compiler (which is unable to cross-compile
719: glibc). diet libc can now be compiled without any include files
720: from a normal libc. The includes do declare more than diet libc
721: currently delivers and they are still far from complete for real
722: applications.
723: I will only add assembly versions that are smaller _and_ faster than
724: the C version. Larger routines are only accepted if they are called
725: very often and are substantially faster.
726: added i386 assembly strchr, which is smaller and faster than the old
727: version. It is, however, larger than the version contributed by
728: proton (thanks, anyway).
729: added i386 strlen (31% faster, 14% smaller)
730: "make t" will now create a map file called "mapfile".
731:
732: 0.6.3:
733: added sys_errlist, strerror and perror
734: added isblank
735: added atol
736:
737: 0.6.2:
738: mmap for ARM didn't compile. Thanks, Paul!
739:
740: 0.6.1:
741: split mmap into the architecture specific subdirectories.
742: getenv now copes with environ==NULL, thanks Paul Clifford.
743: Paul also contributed a smaller ARM startup code.
744:
745: 0.6:
746: strcat returned the wrong result. Thanks, Dietz Pröpper.
747: strtod now understands a negative exponent (oops, thanks Bertram Barth)
748: Port to arm-linux-gnu, but on the Netwinder I use for testing the
749: __dtostr does not work (I have no idea why!)
750: The MIPS port now uses (much smaller) non-PIC code. That means that
751: the applications you link against diet libc also have to be compiled
752: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
753: Thanks to Ralf Bächle for helping me with this!
754: I made subdirectories for the architectures and use VPATH to override
755: VPATH so that make finds the source file automatically. That should
756: simplify the sources greatly.
757: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
758: ARM and MIPS now also have setjmp and longjmp
759: "compile" and "load" are now make targets. Use them for djb programs.
760: added contrib/elftrunc.c which will remove unnecessary ELF headers.
761: Again, contributed from Olaf. Great work!
762:
763: 0.5.12:
764: printf also does signed numbers.
765: If you don't use atexit, dietlibc now does not link exit, only _exit.
766: *printf now correctly returns the number of bytes written.
767: Olaf contributed experimental sscanf and vsscanf implementations.
768: If passed NULL as buffer, snprintf will not write anything but still
769: return the number of bytes it would have written.
770: Initial MIPS port! (Oh, the agony!)
771: No setjmp and longjmp support yet! Please contribute!
772: I even implemented unified syscalls for MIPS. Still, MIPS code is
773: almost twice the size of SPARC code. If anyone knows why: please
774: tell me!
775:
776: 0.5.11:
777: I implemented new unified syscalls for x86, sparc and ppc, this time based
778: on .s files and not .c files, and I moved the syscalls into
779: subdirectores to clean the dietlibc sources up a little.
780: A binary consisting of printf("%s is %d\n","olaf",23) is now
781: 2864 bytes on sparc
782: 2488 bytes on intel
783: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
784: to make a few more applications work.
785: Olaf Dreesen also implemented some unified syscall stuff for x86.
786: He discovered that with our unified syscall interface it actually
787: costs <10 bytes total to make all system calls thread safe!
788: I implemented atexit() (can register up to 4 callbacks).
789: I implemented strtod and __dtostr (the opposite). Now we can add
790: floating point support to vsnprintf and sscanf!
791:
792: 0.5.10:
793: I actually saw that I can not only merge the errno handling code of
794: the system calls on x86, I can also merge the rest (including the
795: arguments) except for setting the system call number. All those
796: system calls are now just a jump to a unified system call handler.
797: I got rid of x86openclose again. The savings are substantial:
798: chown from embutils went from 7664 to 7184 bytes!
799: If I'd move the system call wrappers to assembly language, I could
800: even reduce the alignment (does not matter since it's just a jump
801: anyway) and get rid of the "ret" behind each jump (one byte per
802: system call!)
803:
804: 0.5.9:
805: added memchr, strpbrk, strstr, strtol, isspace (hehe)
806: fixed strdup
807: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
808: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
809: (no signed integers, only strings and unsigned integers (but
810: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
811: that code must be wonderful, I don't understand it at all *bg*)
812: Olaf's printf does understand padding like in "%08d" and "%8d" and
813: automatically pads pointers with '0'.
814: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
815: Thanks to proton for inspiration on this.
816: The new x86 start code also does not reference exit any more, thus saving
817: 64 bytes for executables that don't call exit explicitly.
818: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
819: Moved errno and environ to start.S, saving no byte binary size but
820: speeding up compilation and slightly shortening dietlibc.a ;-)
821: For x86: joined open and close into one assembler file, sharing the
822: errno handling. This is a feasibility test and it actually saves a
823: few bytes. I think I will reimplement the _syscall[1-6] macros on
824: all platforms now to share the errno handling code for them.
825:
826: 0.5.8:
827: fixed strchr to be able to look for 0.
828:
829: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
830: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
831: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
832: contributed by Olaf Dreesen)
833:
834: added execvp, getcwd
835:
836: fixed __xmknod
837:
838: Note: can it be that the ftw interface really is so broken that I
839: cannot implement it without having to implement some searching data
840: structure? I included an experimental ftw implementation that will
841: not follow symlinks.
842:
843: 0.5.7:
844: oops, if_nametoindex was broken!
845:
846: 0.5.6:
847: ported to ppc-linux.
848: fixed i386 sigsetjmp (I mistyped the function name)
849: included sigjmp.c
850:
851: 0.5.5:
852: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
853: actually, it wasn't fork that wasn't working for sparc, it was pipe.
854: I fixed it now.
855: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
856: fixed readdir to use getdents and not the intel inline asm
857:
858: 0.5.4:
859: ported to sparclinux (sparc32 only). Beware: does not work yet.
860: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
861:
862: 0.5.3:
863: added tcsetattr and getenv to compile e3
864:
865: 0.5.2:
866: added vhangup, tcgetattr, isatty and memcmp for fgetty
867: (http://www.fefe.de/fgetty/)
868: added localtime from uC-libc.
869:
870: 0.5.1:
871: stat and friends actually work now. Yuck! Another case of
872: translation between kernel and userland. Why can't the kernel
873: people and the libc people simply agree on a standard?
874: removed many unnecessary includes to speed up compilation.
875: added -fomit-frame-pointer and i386 compilation target to reduce code size.
876: inlined socketcall to reduce code size.
877: "load" and "compile" are examples for djb code.
878:
879: 0.5:
880: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
881: each object file is now treated with "strip -x -R .note -R .comment"
882: split each system call into a separate object file
883: added ntohs, htons, alarm, if_indextoname and if_nametoindex
884:
885: 0.4.1:
886: oops, the strchr implementation was wrong. Thanks Jens Laas!
887:
888: 0.4:
889: copied opendir and friends from uC-libc.
890: added getservent and getservby* in gerservent.c
891:
892: 0.3:
893: remove readdir system call
894: added getdents system call
895: added getpwnam/getpwuid implementation in getpwnam.c
896: added a few string functions (in str*.c)
