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

392 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
393 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
394 it (bug #16298).
395
396 Problem is that for some reason locale fopen's locale.alias with mode "rm".
397
398 -------------------------------------------------------
399 nosferatu root # grep fopen locale.log
400 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
401 nosferatu root #
402 --------------------------------------------------------
403
404 I checked the source of locale, but it have fopen with mode 'r', so
405 not sure where the "rm" mode comes from. Anyhow, changed the check in
406 before_syscall_open_char() to also see mode "rm" as readonly.

408 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
409
410 Add glibc-2.3 support.
411
412 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
413
414 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
415 operations releated to preload, as well as only try to modify ld.so.preload
416 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
417 not using ld.so.preload. Fix to not write this instance of sandbox's pid
418 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
419
420 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
421
422 Changed the LD to CC for hppa.
423
424 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
425
426 Killed the previous changes I made.
427
428 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
429
430 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
431
432 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
433
434 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
435
436 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
437
438 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
439 for this fix.
440
441 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
442
443 sandbox_futils defined a dirname() function that was masking the same
444 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
445 '/usr/lib/portage/bi/'). Fixed function to return expected results and
446 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
447 11231.
448
449 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
450
451 Fix a segfault in libsandbox.c if canonicalize() was called with
452 first parameter = NULL.
453
454 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
455
456 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
457 cleanup() for this.
458
459 Change cleanup() in sandbox.c not to exit with fail status if
460 the pidsfile is missing. We really should still display sandbox
461 violations if they occured.
462
463 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
464
465 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
466 the last sandbox running.
467
468 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
469
470 Major cleanups to mainly libsandbox.c again.
471
472 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
473
474 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
475 parties involved should please contact me so that we can fix it.
476
477 Add opendir wrapper to libsandbox.c.
478
479 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
480
481 Do some more cleanups to ecanonicalize(), as it dropped filenames in
482 rare cases (after my symlink cleanups), and caused glibc to bork.
483 These fixes went into canonicalize.c.
484
485 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
486
487 Fix spawn_shell() and main() in sandbox.c to properly return fail
488 status.
489
490 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
491
492 The new canonicalize() function in libsandbox.c also resolved symlinks,
493 which caused on cleaning sandbox errors if the symlink pointed to a
494 file in the live root. Ripped out canonicalize() and realpath() from
495 glibc; removed the symlink stuff, and changed them to ecanonicalize()
496 and erealpath().
497
498 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
499
500 Ripped out all the wrappers, and implemented those of InstallWatch.
501 Losts of cleanups and bugfixes. Implement a execve that forces
502 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
503 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
504 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
505 parts; it now have an install target.
506
507 Reformat the whole thing to look somewhat like the reworked sandbox.c
508 and new sandbox.h and sandbox_futils.c from:
509
510 Brad House <brad@mainstreetsoftworks.com>.

512 Additional Copyrights now due to the InstallWatch code:
