5 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
7 by Marcus D. Hanwell <cryos@gentoo.org>.
8
9 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
10 Add /dev/console to write list, bug #38588.
11
12 * sandbox-1.2.8 (2005/05/13)
13
14 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
15 sandbox.h, sandbox_futils.c:
16 General cleanups.
17
18 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
19 sandbox.h:
20 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
21
22 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
23 sandbox.h, sandbox_futils.c:
24 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
25 to use TMPDIR if present in environment.
26
27 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
28 Remove sandbox_log_file from main() as its no longer used.
29
30 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
31 sandbox_futils.c:
32 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
33 if already exported when sandbox started). Fix get_sandbox_log() and new
34 get_sandbox_debug_log() to not use already exported environment variables if
35 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
36 SB_PATH_MAX fixes.
37
38 * sandbox-1.2.7 (2005/05/12)
39
40 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
41 sandbox_futils.c:
42 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
43
44 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
45 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
46 with '(null)' in it if we did not call sandbox with absolute path.
47
48 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
49 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
50 for the child.
51
52 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
53 Remove global preload_adaptable as it is no longer used.
54
55 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
56 Rewrite environment stuff to only be set when execve'ing the child process
57 to try and avoid issues like bug #91541 that causes sandbox to crash if
58 we set LD_PRELOAD sandbox side already.
59
60 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
61 Move print_sandbox_log() up to make things neater.
62
63 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
64 Remove load_preload_libs(), as its not used anymore.
65
66 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
67 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
68
69 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
70 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
71
72 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
73 Remove ld.so.preload crap - we are not going to use it again.
74
75 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
76 Fix typo in code that checks if we got valid group information, causing a
77 segmentation fault, bug #91637.
78
79 * sandbox-1.2.6 (2005/05/10)
80
81 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
82 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
83 for some odd reason, bug #91541.
84
85 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
86 Fix typo (sizeof -> strlen).
87
88 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
89 rewrote the sbcontext caching code so it accounts for env changes since lib
90 initialization.
91
92 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
93 We create libctest.c via configure, so no need to keep it around. Do some
94 cleanup related to libctest.c and libctest during configure.
95
96 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
97 Add rename support of symlinks pointing to protected files/directories.
98
99 * sandbox-1.2.5 (2005/05/04)
100
101 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
102 sandbox.bashrc:
103 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
104 already set, init of the env vars fails for some reason, so do this later on,
105 and do not warn (bug #91431).
106
107 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
108 sandbox.bashrc:
109 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
110
111 * sandbox-1.2.4 (2005/05/03)
112
113 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
114 Do not init the env entries with each call, as it creates too many calls to
115 lstat, etc. Should speedup things a bit, bug #91040.
116
117 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
118 Add /dev/pty to default write list. Noticed by Morfic.
119
120 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
121 sandbox.h:
122 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
123 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
124
125 * sandbox-1.2.3 (2005/04/29)
126
127 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
128 Do not check for (*&#$(* CXX or F77.
129
130 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
131 Do not append '/' to pathname in filter_path() if it already ends with it.
132
133 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
134 With az's help, clean up autotools to work with cross-compiling.
135
136 * sandbox-1.2.2 (2005/04/28)
137
138 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
139 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
140 have issues; bug #90592.
141
142 * sandbox-1.2.1 (2005/04/23)
143
144 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
145 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
146 Make sure all functions used in libsandbox.c is declared static. Define
147 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
148 linking with its object. Hopefully this will fix bug #90153.
149
150 * sandbox-1.2 (2005/04/23)
151
152 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
153 Allow lchown a symlink in write-allowed path pointing to write-denied
154 target.
155
156 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
157 Also show resolved symlink names in the log.
158
159 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
160 Seems -nostdlib was the problem with the constructor/destructor - remove it
161 from Makefile.am, and change the constructor/destructor names again.
162
163 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
164 Also rename the _init() and _fini() declarations.
165
166 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
167 Fixup the constructor/destructor function names again (they should be _init()
168 and _fini() it seems, and not being called caused sandbox_lib_path to be
169 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
170 Add both the path in given SANDBOX_x variable, as well as its symlink
171 resolved path in init_env_entries(). Modify filter_path() to be able to
172 resolve paths without resolving symlinks, as well as to be able to resolve
173 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
174 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
175 for bug #31019 cause access violations if we try to remove a symlink that is
176 not in protected path, but points to a protected path. Fix a memory leak in
177 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
178 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
179 (pid_string was uninitialized). General syntax cleanups.
180
181 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
182 infamous "pids file is not a regular file" w/out newline bug.
183
184 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
185 Correct libc_version path detection, since it was screwing up if libdir !=
186 "/lib/".
187
188 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
189 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
190
191 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
192 Fix symbols.in not added to dist.
193
194 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
195 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
196 White space fixes.
197
198 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
199 configure.in, getcwd.c, libsandbox.c, symbols.in:
200 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
201 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
202 for glibc and other libc's that use this. Update libsandbox.c to use these
203 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
204 process unset it.
205
206 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
207 killed off _init and _fini in favor of
208 void __attribute__ ((constructor)) init_func and
209 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
210
211 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
212 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
213 having the hick-ups.
214
215 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
216 Makefile.am: Fixed compilation.
217
218 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
219 Gutted the bugger so it stops checking for a c++ and fortran compiler.
220 Do *not* regenerate aclocal.m4 for making a release until a better
221 solution is created.
222
223 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
224 Removal of more hardcoded paths.
225
226 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
227 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
228
229 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
230 Sandbox is now autotooled, create-localdecls needs to be killed and the code
231 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
232 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
233 To get to a point of testing, automake && autoconf; created requisite files w/
234 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
235 /lib and /usr/lib/portage/bin.
236
237 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
238 closing out bug #70225, potential overflow of the sandbox_pids_file var.
239
240 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
241 (think it was at least) allows intermixing of code and data segments. bug #70351
242 should be fixed by this.
243
244 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
245 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
246
247 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
248 Seth Robertson that tracked down all adjuct flags for read operations that
249 do not invoke a write operation.
250
251 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
252 Another fix from jstubbs regarding a free() on a stack variable for the
253 environment -- tracking now prevents extraneous free()'s segfault.
254
255 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
256 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
257 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
258 Also remove the errno = ESUCCESS settings as documentation points out that
259 a library isn't allowed to do that.
260
261 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
262 file_security_check() function to check random potential exploits on files
263 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
264 the 'system-crippling' exploits (bug 21923) and catches a few other
265 potential problems.
266
267 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
268 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
269
270 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
271 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
272 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
273
274 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
275 Fix permissions and group of pids file and logs. Permissions should be 0664
276 and group should be 'portage'. Bug #34260.
277
278 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
279 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
280 to the real execve (in our execve wrapper). Seems that on some arches (sparc
281 among others) do not allow us to tamper with the readonly copy passed to
282 execve, so pass our own copy of the environment. Bug #42290.
283
284 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
285 Changed tail to head and added a notice about duration of glibc check.
286
287 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
288 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
289 as there isn't a guarentee that it is dynamic.
290
291 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
292 If 'file' passed to before_syscall(const char *func, const char *file) is
293 invalid, we should set errno to ENOENT, and not EINVAL. This should
294 close bug #32238.
295
296 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
297 Fix a bug that occurs mainly on 64bit arch, where the file passed to
298 the functions we wrap, is invalid, and then cause canonicalize to pass
299 garbage to before_syscall(), thanks to great detective work from
300 Andrea Luzzardi <al@sig11.org> (bug #29846).
301
302 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
303 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
304
305 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
306 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
307 only checked the destination patch, and not the source, so we could move
308 a protected file to a unprotected directory, and then delete/modify it.
309 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
310
311 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
312 Added python2.3 to the predict section/variable.
313
314 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
315 sandbox.h, sandbox_futils.c :
316 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
317 it is not set, it will revert to its old value.
318
319 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
320 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
321 rather than failing with a violation, bug #29748.
322
323 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
324 Fix canonicalize() to ignore calls with path = "".
325
326 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
327 sandbox_futils.c, canonicalize.c :
328 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
329 call handled strings larger than PATH_MAX (bug #21766). It however does not
330 work the same on 2.4 kernels.
331
332 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
333 do not need the system call. We use the default getcwd() function via a
334 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
335 means the current directory was removed, OR that the the system call for
336 getcwd failed (curious is that it do not fail and return NULL or set
337 errno, but rather just truncate the retured directory - usually from the
338 start), and if so, we use the generic getcwd() function (__egetcwd). Note
339 that we do not use the generic version all the time, as it calls lstat()
340 a great number of times, and performance degrade much.
341
342 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
343 libsandbox.c :
344 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
345
346 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
347 create-localdecls :
348 When checking path names of files accessed, we need to canonicalize it, else
349 it may be a symlink in a 'write allowed' directory pointing to a file in a
350 directory we should not have write access to.
351
352 With something like coreutils-5.0, we have two problems:
353 1) One of the tests checks if getcwd() can return a path longer than
354 PATH_MAX. This test then tries to create a dir which even while
355 created local (mkdir("conftest2")), it ends up being resolved with
356 a name that is much larger than PATH_MAX. The problem now is that
357 canonicalize() have undefined behaviour when the path was too long
358 (returned wrongly truncated paths, etc), and pass the wrong path to
359 before_syscall() (causing the bogus sandbox violations).
360 2) The ecanonicalize() function we used, along with the canonicalize()
361 function did not support longer than PATH_MAX. This is partly a
362 cause for 1), but the error checking (rather lack of it) of calls
363 to erealpath() in canonicalize() was the prime reason for 1).
364
365 As we do not use this canonicalized name to call the function, we resolve this
366 by fixing canonicalize() to do better error checking, and ecanonicalize() as
367 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
368 While they will resolve paths properly now, and can check if a write/read is
369 allowed, the functions called from the sandboxed environment will still work
370 as expected.
371
372 This should resolve bug #21766.
373
374 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
375 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
376 it (bug #16298).
377
378 Problem is that for some reason locale fopen's locale.alias with mode "rm".
379
380 -------------------------------------------------------
381 nosferatu root # grep fopen locale.log
382 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
383 nosferatu root #
384 --------------------------------------------------------
385
386 I checked the source of locale, but it have fopen with mode 'r', so
387 not sure where the "rm" mode comes from. Anyhow, changed the check in
388 before_syscall_open_char() to also see mode "rm" as readonly.
389
390 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
391
392 Add glibc-2.3 support.
393
394 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :

396 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
397 operations releated to preload, as well as only try to modify ld.so.preload
398 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
399 not using ld.so.preload. Fix to not write this instance of sandbox's pid
400 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.

402 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
403
404 Changed the LD to CC for hppa.
405
406 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
407
408 Killed the previous changes I made.
409
410 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
411
412 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
413
414 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
415
416 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
417
418 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
419
420 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
421 for this fix.
422
423 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
424
425 sandbox_futils defined a dirname() function that was masking the same
426 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
427 '/usr/lib/portage/bi/'). Fixed function to return expected results and
428 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
429 11231.
430
431 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
432
433 Fix a segfault in libsandbox.c if canonicalize() was called with
434 first parameter = NULL.
435
436 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
437
438 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
439 cleanup() for this.
440
441 Change cleanup() in sandbox.c not to exit with fail status if
442 the pidsfile is missing. We really should still display sandbox
443 violations if they occured.
444
445 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
446
447 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
448 the last sandbox running.
449
450 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
451
452 Major cleanups to mainly libsandbox.c again.
453
454 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
455
456 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
457 parties involved should please contact me so that we can fix it.
458
459 Add opendir wrapper to libsandbox.c.
460
461 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
462
463 Do some more cleanups to ecanonicalize(), as it dropped filenames in
464 rare cases (after my symlink cleanups), and caused glibc to bork.
465 These fixes went into canonicalize.c.
466
467 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
468
469 Fix spawn_shell() and main() in sandbox.c to properly return fail
470 status.
471
472 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
473
474 The new canonicalize() function in libsandbox.c also resolved symlinks,
475 which caused on cleaning sandbox errors if the symlink pointed to a
476 file in the live root. Ripped out canonicalize() and realpath() from
477 glibc; removed the symlink stuff, and changed them to ecanonicalize()
478 and erealpath().
479
480 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
481
482 Ripped out all the wrappers, and implemented those of InstallWatch.
483 Losts of cleanups and bugfixes. Implement a execve that forces
484 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
485 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
486 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
487 parts; it now have an install target.
488
489 Reformat the whole thing to look somewhat like the reworked sandbox.c
490 and new sandbox.h and sandbox_futils.c from:
491
492 Brad House <brad@mainstreetsoftworks.com>.
493
494 Additional Copyrights now due to the InstallWatch code:
