Be default we will fail if the path name we try to canonicalize is too long.
This however could cause issues with some things (bug #94630 and #21766), so
if fail_nametoolong == 0, canonicalize() will return a null length string and
do not fail.

5 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6 Be default we will fail if the path name we try to canonicalize is too long.
7 This however could cause issues with some things (bug #94630 and #21766), so
8 if fail_nametoolong == 0, canonicalize() will return a null length string and
9 do not fail.
10
11 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
12 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
13 make sure we re-export the new TMPDIR environment variable.
14
15 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
16 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
17 by Marcus D. Hanwell <cryos@gentoo.org>.
18
19 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
20 Add /dev/console to write list, bug #38588.
21
22 * sandbox-1.2.8 (2005/05/13)
23
24 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
25 sandbox.h, sandbox_futils.c:
26 General cleanups.
27
28 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
29 sandbox.h:
30 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
31
32 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
33 sandbox.h, sandbox_futils.c:
34 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
35 to use TMPDIR if present in environment.
36
37 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
38 Remove sandbox_log_file from main() as its no longer used.
39
40 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
41 sandbox_futils.c:
42 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
43 if already exported when sandbox started). Fix get_sandbox_log() and new
44 get_sandbox_debug_log() to not use already exported environment variables if
45 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
46 SB_PATH_MAX fixes.
47
48 * sandbox-1.2.7 (2005/05/12)
49
50 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
51 sandbox_futils.c:
52 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
53
54 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
55 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
56 with '(null)' in it if we did not call sandbox with absolute path.
57
58 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
59 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
60 for the child.
61
62 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
63 Remove global preload_adaptable as it is no longer used.
64
65 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
66 Rewrite environment stuff to only be set when execve'ing the child process
67 to try and avoid issues like bug #91541 that causes sandbox to crash if
68 we set LD_PRELOAD sandbox side already.
69
70 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
71 Move print_sandbox_log() up to make things neater.
72
73 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
74 Remove load_preload_libs(), as its not used anymore.
75
76 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
77 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
78
79 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
80 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
81
82 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
83 Remove ld.so.preload crap - we are not going to use it again.
84
85 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
86 Fix typo in code that checks if we got valid group information, causing a
87 segmentation fault, bug #91637.
88
89 * sandbox-1.2.6 (2005/05/10)
90
91 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
92 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
93 for some odd reason, bug #91541.
94
95 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
96 Fix typo (sizeof -> strlen).
97
98 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
99 rewrote the sbcontext caching code so it accounts for env changes since lib
100 initialization.
101
102 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
103 We create libctest.c via configure, so no need to keep it around. Do some
104 cleanup related to libctest.c and libctest during configure.
105
106 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
107 Add rename support of symlinks pointing to protected files/directories.
108
109 * sandbox-1.2.5 (2005/05/04)
110
111 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
112 sandbox.bashrc:
113 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
114 already set, init of the env vars fails for some reason, so do this later on,
115 and do not warn (bug #91431).
116
117 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
118 sandbox.bashrc:
119 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
120
121 * sandbox-1.2.4 (2005/05/03)
122
123 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
124 Do not init the env entries with each call, as it creates too many calls to
125 lstat, etc. Should speedup things a bit, bug #91040.
126
127 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
128 Add /dev/pty to default write list. Noticed by Morfic.
129
130 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
131 sandbox.h:
132 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
133 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
134
135 * sandbox-1.2.3 (2005/04/29)
136
137 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
138 Do not check for (*&#$(* CXX or F77.
139
140 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
141 Do not append '/' to pathname in filter_path() if it already ends with it.
142
143 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
144 With az's help, clean up autotools to work with cross-compiling.
145
146 * sandbox-1.2.2 (2005/04/28)
147
148 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
149 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
150 have issues; bug #90592.
151
152 * sandbox-1.2.1 (2005/04/23)
153
154 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
155 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
156 Make sure all functions used in libsandbox.c is declared static. Define
157 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
158 linking with its object. Hopefully this will fix bug #90153.
159
160 * sandbox-1.2 (2005/04/23)
161
162 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
163 Allow lchown a symlink in write-allowed path pointing to write-denied
164 target.
165
166 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
167 Also show resolved symlink names in the log.
168
169 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
170 Seems -nostdlib was the problem with the constructor/destructor - remove it
171 from Makefile.am, and change the constructor/destructor names again.
172
173 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
174 Also rename the _init() and _fini() declarations.
175
176 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
177 Fixup the constructor/destructor function names again (they should be _init()
178 and _fini() it seems, and not being called caused sandbox_lib_path to be
179 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
180 Add both the path in given SANDBOX_x variable, as well as its symlink
181 resolved path in init_env_entries(). Modify filter_path() to be able to
182 resolve paths without resolving symlinks, as well as to be able to resolve
183 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
184 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
185 for bug #31019 cause access violations if we try to remove a symlink that is
186 not in protected path, but points to a protected path. Fix a memory leak in
187 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
188 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
189 (pid_string was uninitialized). General syntax cleanups.
190
191 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
192 infamous "pids file is not a regular file" w/out newline bug.
193
194 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
195 Correct libc_version path detection, since it was screwing up if libdir !=
196 "/lib/".
197
198 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
199 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
200
201 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
202 Fix symbols.in not added to dist.
203
204 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
205 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
206 White space fixes.
207
208 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
209 configure.in, getcwd.c, libsandbox.c, symbols.in:
210 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
211 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
212 for glibc and other libc's that use this. Update libsandbox.c to use these
213 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
214 process unset it.
215
216 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
217 killed off _init and _fini in favor of
218 void __attribute__ ((constructor)) init_func and
219 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
220
221 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
222 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
223 having the hick-ups.
224
225 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
226 Makefile.am: Fixed compilation.
227
228 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
229 Gutted the bugger so it stops checking for a c++ and fortran compiler.
230 Do *not* regenerate aclocal.m4 for making a release until a better
231 solution is created.
232
233 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
234 Removal of more hardcoded paths.
235
236 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
237 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
238
239 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
240 Sandbox is now autotooled, create-localdecls needs to be killed and the code
241 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
242 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
243 To get to a point of testing, automake && autoconf; created requisite files w/
244 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
245 /lib and /usr/lib/portage/bin.
246
247 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
248 closing out bug #70225, potential overflow of the sandbox_pids_file var.
249
250 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
251 (think it was at least) allows intermixing of code and data segments. bug #70351
252 should be fixed by this.
253
254 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
255 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
256
257 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
258 Seth Robertson that tracked down all adjuct flags for read operations that
259 do not invoke a write operation.
260
261 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
262 Another fix from jstubbs regarding a free() on a stack variable for the
263 environment -- tracking now prevents extraneous free()'s segfault.
264
265 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
266 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
267 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
268 Also remove the errno = ESUCCESS settings as documentation points out that
269 a library isn't allowed to do that.
270
271 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
272 file_security_check() function to check random potential exploits on files
273 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
274 the 'system-crippling' exploits (bug 21923) and catches a few other
275 potential problems.
276
277 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
278 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
279
280 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
281 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
282 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
283
284 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
285 Fix permissions and group of pids file and logs. Permissions should be 0664
286 and group should be 'portage'. Bug #34260.
287
288 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
289 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
290 to the real execve (in our execve wrapper). Seems that on some arches (sparc
291 among others) do not allow us to tamper with the readonly copy passed to
292 execve, so pass our own copy of the environment. Bug #42290.
293
294 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
295 Changed tail to head and added a notice about duration of glibc check.
296
297 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
298 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
299 as there isn't a guarentee that it is dynamic.
300
301 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
302 If 'file' passed to before_syscall(const char *func, const char *file) is
303 invalid, we should set errno to ENOENT, and not EINVAL. This should
304 close bug #32238.
305
306 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
307 Fix a bug that occurs mainly on 64bit arch, where the file passed to
308 the functions we wrap, is invalid, and then cause canonicalize to pass
309 garbage to before_syscall(), thanks to great detective work from
310 Andrea Luzzardi <al@sig11.org> (bug #29846).
311
312 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
313 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
314
315 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
316 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
317 only checked the destination patch, and not the source, so we could move
318 a protected file to a unprotected directory, and then delete/modify it.
319 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
320
321 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
322 Added python2.3 to the predict section/variable.
323
324 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
325 sandbox.h, sandbox_futils.c :
326 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
327 it is not set, it will revert to its old value.
328
329 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
330 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
331 rather than failing with a violation, bug #29748.
332
333 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
334 Fix canonicalize() to ignore calls with path = "".
335
336 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
337 sandbox_futils.c, canonicalize.c :
338 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
339 call handled strings larger than PATH_MAX (bug #21766). It however does not
340 work the same on 2.4 kernels.
341
342 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
343 do not need the system call. We use the default getcwd() function via a
344 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
345 means the current directory was removed, OR that the the system call for
346 getcwd failed (curious is that it do not fail and return NULL or set
347 errno, but rather just truncate the retured directory - usually from the
348 start), and if so, we use the generic getcwd() function (__egetcwd). Note
349 that we do not use the generic version all the time, as it calls lstat()
350 a great number of times, and performance degrade much.
351
352 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
353 libsandbox.c :
354 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
355
356 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
357 create-localdecls :
358 When checking path names of files accessed, we need to canonicalize it, else
359 it may be a symlink in a 'write allowed' directory pointing to a file in a
360 directory we should not have write access to.
361
362 With something like coreutils-5.0, we have two problems:
363 1) One of the tests checks if getcwd() can return a path longer than
364 PATH_MAX. This test then tries to create a dir which even while
365 created local (mkdir("conftest2")), it ends up being resolved with
366 a name that is much larger than PATH_MAX. The problem now is that
367 canonicalize() have undefined behaviour when the path was too long
368 (returned wrongly truncated paths, etc), and pass the wrong path to
369 before_syscall() (causing the bogus sandbox violations).
370 2) The ecanonicalize() function we used, along with the canonicalize()
371 function did not support longer than PATH_MAX. This is partly a
372 cause for 1), but the error checking (rather lack of it) of calls
373 to erealpath() in canonicalize() was the prime reason for 1).
374
375 As we do not use this canonicalized name to call the function, we resolve this
376 by fixing canonicalize() to do better error checking, and ecanonicalize() as
377 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
378 While they will resolve paths properly now, and can check if a write/read is
379 allowed, the functions called from the sandboxed environment will still work
380 as expected.
381
382 This should resolve bug #21766.
383
384 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
385 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
386 it (bug #16298).
387
388 Problem is that for some reason locale fopen's locale.alias with mode "rm".
389

396 I checked the source of locale, but it have fopen with mode 'r', so
397 not sure where the "rm" mode comes from. Anyhow, changed the check in
398 before_syscall_open_char() to also see mode "rm" as readonly.

400 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
401
402 Add glibc-2.3 support.
403
404 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
405
406 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
407 operations releated to preload, as well as only try to modify ld.so.preload
408 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
409 not using ld.so.preload. Fix to not write this instance of sandbox's pid
410 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
411
412 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
413
414 Changed the LD to CC for hppa.
415
416 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
417
418 Killed the previous changes I made.
419
420 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
421
422 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
423
424 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
425
426 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
427
428 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
429
430 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
431 for this fix.
432
433 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
434
435 sandbox_futils defined a dirname() function that was masking the same
436 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
437 '/usr/lib/portage/bi/'). Fixed function to return expected results and
438 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
439 11231.
440
441 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
442
443 Fix a segfault in libsandbox.c if canonicalize() was called with
444 first parameter = NULL.
445
446 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
447
448 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
449 cleanup() for this.
450
451 Change cleanup() in sandbox.c not to exit with fail status if
452 the pidsfile is missing. We really should still display sandbox
453 violations if they occured.
454
455 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
456
457 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
458 the last sandbox running.
459
460 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
461
462 Major cleanups to mainly libsandbox.c again.
463
464 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
465
466 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
467 parties involved should please contact me so that we can fix it.
468
469 Add opendir wrapper to libsandbox.c.
470
471 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
472
473 Do some more cleanups to ecanonicalize(), as it dropped filenames in
474 rare cases (after my symlink cleanups), and caused glibc to bork.
475 These fixes went into canonicalize.c.
476
477 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
478
479 Fix spawn_shell() and main() in sandbox.c to properly return fail
480 status.
481
482 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
483
484 The new canonicalize() function in libsandbox.c also resolved symlinks,
485 which caused on cleaning sandbox errors if the symlink pointed to a
486 file in the live root. Ripped out canonicalize() and realpath() from
487 glibc; removed the symlink stuff, and changed them to ecanonicalize()
488 and erealpath().
489
490 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
491
492 Ripped out all the wrappers, and implemented those of InstallWatch.
493 Losts of cleanups and bugfixes. Implement a execve that forces
494 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
495 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
496 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
497 parts; it now have an install target.
498
499 Reformat the whole thing to look somewhat like the reworked sandbox.c
500 and new sandbox.h and sandbox_futils.c from:
501
502 Brad House <brad@mainstreetsoftworks.com>.
503
504 Additional Copyrights now due to the InstallWatch code:
