4
5 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
6 sandbox.h:
7 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
8
9 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
10 sandbox.h, sandbox_futils.c:
11 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
12 to use TMPDIR if present in environment.
13
14 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
15 Remove sandbox_log_file from main() as its no longer used.
16
17 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
18 sandbox_futils.c:
19 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
20 if already exported when sandbox started). Fix get_sandbox_log() and new
21 get_sandbox_debug_log() to not use already exported environment variables if
22 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
23 SB_PATH_MAX fixes.
24
25 * sandbox-1.2.7 (2005/05/12)
26
27 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
28 sandbox_futils.c:
29 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
30
31 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
32 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
33 with '(null)' in it if we did not call sandbox with absolute path.
34
35 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
36 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
37 for the child.
38
39 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
40 Remove global preload_adaptable as it is no longer used.
41
42 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
43 Rewrite environment stuff to only be set when execve'ing the child process
44 to try and avoid issues like bug #91541 that causes sandbox to crash if
45 we set LD_PRELOAD sandbox side already.
46
47 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
48 Move print_sandbox_log() up to make things neater.
49
50 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
51 Remove load_preload_libs(), as its not used anymore.
52
53 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
54 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
55
56 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
57 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
58
59 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
60 Remove ld.so.preload crap - we are not going to use it again.
61
62 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
63 Fix typo in code that checks if we got valid group information, causing a
64 segmentation fault, bug #91637.
65
66 * sandbox-1.2.6 (2005/05/10)
67
68 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
69 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
70 for some odd reason, bug #91541.
71
72 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
73 Fix typo (sizeof -> strlen).
74
75 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
76 rewrote the sbcontext caching code so it accounts for env changes since lib
77 initialization.
78
79 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
80 We create libctest.c via configure, so no need to keep it around. Do some
81 cleanup related to libctest.c and libctest during configure.
82
83 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
84 Add rename support of symlinks pointing to protected files/directories.
85
86 * sandbox-1.2.5 (2005/05/04)
87
88 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
89 sandbox.bashrc:
90 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
91 already set, init of the env vars fails for some reason, so do this later on,
92 and do not warn (bug #91431).
93
94 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
95 sandbox.bashrc:
96 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
97
98 * sandbox-1.2.4 (2005/05/03)
99
100 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
101 Do not init the env entries with each call, as it creates too many calls to
102 lstat, etc. Should speedup things a bit, bug #91040.
103
104 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
105 Add /dev/pty to default write list. Noticed by Morfic.
106
107 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
108 sandbox.h:
109 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
110 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
111
112 * sandbox-1.2.3 (2005/04/29)
113
114 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
115 Do not check for (*&#$(* CXX or F77.
116
117 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
118 Do not append '/' to pathname in filter_path() if it already ends with it.
119
120 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
121 With az's help, clean up autotools to work with cross-compiling.
122
123 * sandbox-1.2.2 (2005/04/28)
124
125 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
126 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
127 have issues; bug #90592.
128
129 * sandbox-1.2.1 (2005/04/23)
130
131 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
132 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
133 Make sure all functions used in libsandbox.c is declared static. Define
134 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
135 linking with its object. Hopefully this will fix bug #90153.
136
137 * sandbox-1.2 (2005/04/23)
138
139 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
140 Allow lchown a symlink in write-allowed path pointing to write-denied
141 target.
142
143 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
144 Also show resolved symlink names in the log.
145
146 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
147 Seems -nostdlib was the problem with the constructor/destructor - remove it
148 from Makefile.am, and change the constructor/destructor names again.
149
150 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
151 Also rename the _init() and _fini() declarations.
152
153 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
154 Fixup the constructor/destructor function names again (they should be _init()
155 and _fini() it seems, and not being called caused sandbox_lib_path to be
156 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
157 Add both the path in given SANDBOX_x variable, as well as its symlink
158 resolved path in init_env_entries(). Modify filter_path() to be able to
159 resolve paths without resolving symlinks, as well as to be able to resolve
160 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
161 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
162 for bug #31019 cause access violations if we try to remove a symlink that is
163 not in protected path, but points to a protected path. Fix a memory leak in
164 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
165 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
166 (pid_string was uninitialized). General syntax cleanups.
167
168 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
169 infamous "pids file is not a regular file" w/out newline bug.
170
171 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
172 Correct libc_version path detection, since it was screwing up if libdir !=
173 "/lib/".
174
175 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
176 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
177
178 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
179 Fix symbols.in not added to dist.
180
181 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
182 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
183 White space fixes.
184
185 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
186 configure.in, getcwd.c, libsandbox.c, symbols.in:
187 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
188 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
189 for glibc and other libc's that use this. Update libsandbox.c to use these
190 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
191 process unset it.
192
193 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
194 killed off _init and _fini in favor of
195 void __attribute__ ((constructor)) init_func and
196 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
197
198 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
199 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
200 having the hick-ups.
201
202 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
203 Makefile.am: Fixed compilation.
204
205 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
206 Gutted the bugger so it stops checking for a c++ and fortran compiler.
207 Do *not* regenerate aclocal.m4 for making a release until a better
208 solution is created.
209
210 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
211 Removal of more hardcoded paths.
212
213 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
214 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
215
216 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
217 Sandbox is now autotooled, create-localdecls needs to be killed and the code
218 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
219 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
220 To get to a point of testing, automake && autoconf; created requisite files w/
221 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
222 /lib and /usr/lib/portage/bin.
223
224 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
225 closing out bug #70225, potential overflow of the sandbox_pids_file var.
226
227 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
228 (think it was at least) allows intermixing of code and data segments. bug #70351
229 should be fixed by this.
230
231 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
232 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
233
234 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
235 Seth Robertson that tracked down all adjuct flags for read operations that
236 do not invoke a write operation.
237
238 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
239 Another fix from jstubbs regarding a free() on a stack variable for the
240 environment -- tracking now prevents extraneous free()'s segfault.
241
242 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
243 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
244 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
245 Also remove the errno = ESUCCESS settings as documentation points out that
246 a library isn't allowed to do that.
247
248 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
249 file_security_check() function to check random potential exploits on files
250 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
251 the 'system-crippling' exploits (bug 21923) and catches a few other
252 potential problems.
253
254 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
255 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
256
257 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
258 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
259 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
260
261 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
262 Fix permissions and group of pids file and logs. Permissions should be 0664
263 and group should be 'portage'. Bug #34260.
264
265 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
266 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
267 to the real execve (in our execve wrapper). Seems that on some arches (sparc
268 among others) do not allow us to tamper with the readonly copy passed to
269 execve, so pass our own copy of the environment. Bug #42290.
270
271 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
272 Changed tail to head and added a notice about duration of glibc check.
273
274 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
275 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
276 as there isn't a guarentee that it is dynamic.
277
278 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
279 If 'file' passed to before_syscall(const char *func, const char *file) is
280 invalid, we should set errno to ENOENT, and not EINVAL. This should
281 close bug #32238.
282
283 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
284 Fix a bug that occurs mainly on 64bit arch, where the file passed to
285 the functions we wrap, is invalid, and then cause canonicalize to pass
286 garbage to before_syscall(), thanks to great detective work from
287 Andrea Luzzardi <al@sig11.org> (bug #29846).
288
289 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
290 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
291
292 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
293 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
294 only checked the destination patch, and not the source, so we could move
295 a protected file to a unprotected directory, and then delete/modify it.
296 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
297
298 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
299 Added python2.3 to the predict section/variable.
300
301 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
302 sandbox.h, sandbox_futils.c :
303 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
304 it is not set, it will revert to its old value.
305
306 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
307 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
308 rather than failing with a violation, bug #29748.
309
310 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
311 Fix canonicalize() to ignore calls with path = "".
312
313 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
314 sandbox_futils.c, canonicalize.c :
315 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
316 call handled strings larger than PATH_MAX (bug #21766). It however does not
317 work the same on 2.4 kernels.
318
319 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
320 do not need the system call. We use the default getcwd() function via a
321 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
322 means the current directory was removed, OR that the the system call for
323 getcwd failed (curious is that it do not fail and return NULL or set
324 errno, but rather just truncate the retured directory - usually from the
325 start), and if so, we use the generic getcwd() function (__egetcwd). Note
326 that we do not use the generic version all the time, as it calls lstat()
327 a great number of times, and performance degrade much.
328
329 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
330 libsandbox.c :
331 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
332
333 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
334 create-localdecls :
335 When checking path names of files accessed, we need to canonicalize it, else
336 it may be a symlink in a 'write allowed' directory pointing to a file in a
337 directory we should not have write access to.
338
339 With something like coreutils-5.0, we have two problems:
340 1) One of the tests checks if getcwd() can return a path longer than
341 PATH_MAX. This test then tries to create a dir which even while
342 created local (mkdir("conftest2")), it ends up being resolved with
343 a name that is much larger than PATH_MAX. The problem now is that
344 canonicalize() have undefined behaviour when the path was too long
345 (returned wrongly truncated paths, etc), and pass the wrong path to
346 before_syscall() (causing the bogus sandbox violations).
347 2) The ecanonicalize() function we used, along with the canonicalize()
348 function did not support longer than PATH_MAX. This is partly a
349 cause for 1), but the error checking (rather lack of it) of calls
350 to erealpath() in canonicalize() was the prime reason for 1).
351
352 As we do not use this canonicalized name to call the function, we resolve this
353 by fixing canonicalize() to do better error checking, and ecanonicalize() as
354 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
355 While they will resolve paths properly now, and can check if a write/read is
356 allowed, the functions called from the sandboxed environment will still work
357 as expected.
358
359 This should resolve bug #21766.
360
361 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
362 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
363 it (bug #16298).
364
365 Problem is that for some reason locale fopen's locale.alias with mode "rm".
366
367 -------------------------------------------------------
368 nosferatu root # grep fopen locale.log
369 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
370 nosferatu root #
371 --------------------------------------------------------
372
373 I checked the source of locale, but it have fopen with mode 'r', so
374 not sure where the "rm" mode comes from. Anyhow, changed the check in
375 before_syscall_open_char() to also see mode "rm" as readonly.
376
377 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
378
379 Add glibc-2.3 support.
380
381 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
382
383 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
384 operations releated to preload, as well as only try to modify ld.so.preload
385 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
386 not using ld.so.preload. Fix to not write this instance of sandbox's pid
387 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
388
389 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
390
391 Changed the LD to CC for hppa.
392
393 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
394
395 Killed the previous changes I made.
396
397 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
398
399 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
400
401 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
402
403 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
404
405 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
406
407 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
408 for this fix.
409
410 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
411
412 sandbox_futils defined a dirname() function that was masking the same
413 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
414 '/usr/lib/portage/bi/'). Fixed function to return expected results and
415 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
416 11231.
417
418 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
419
420 Fix a segfault in libsandbox.c if canonicalize() was called with
421 first parameter = NULL.
422
423 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
424
425 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
426 cleanup() for this.
427
428 Change cleanup() in sandbox.c not to exit with fail status if
429 the pidsfile is missing. We really should still display sandbox
430 violations if they occured.
431
432 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
433
434 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
435 the last sandbox running.
436
437 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
438
439 Major cleanups to mainly libsandbox.c again.
440
441 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
442
443 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
444 parties involved should please contact me so that we can fix it.
445
446 Add opendir wrapper to libsandbox.c.
447
448 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
449
450 Do some more cleanups to ecanonicalize(), as it dropped filenames in
451 rare cases (after my symlink cleanups), and caused glibc to bork.
452 These fixes went into canonicalize.c.
453
454 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
455
456 Fix spawn_shell() and main() in sandbox.c to properly return fail
457 status.
458
459 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
460
461 The new canonicalize() function in libsandbox.c also resolved symlinks,
462 which caused on cleaning sandbox errors if the symlink pointed to a
463 file in the live root. Ripped out canonicalize() and realpath() from
464 glibc; removed the symlink stuff, and changed them to ecanonicalize()
465 and erealpath().
466
467 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
468
469 Ripped out all the wrappers, and implemented those of InstallWatch.
470 Losts of cleanups and bugfixes. Implement a execve that forces
471 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
472 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
473 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
474 parts; it now have an install target.
475
476 Reformat the whole thing to look somewhat like the reworked sandbox.c
477 and new sandbox.h and sandbox_futils.c from:
478
479 Brad House <brad@mainstreetsoftworks.com>.
480
481 Additional Copyrights now due to the InstallWatch code:
