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