5 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
6 Add /dev/console to write list, bug #38588.
7
8 * sandbox-1.2.8 (2005/05/13)
9
10 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
11 sandbox.h, sandbox_futils.c:
12 General cleanups.
13
14 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
15 sandbox.h:
16 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
17
18 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
19 sandbox.h, sandbox_futils.c:
20 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
21 to use TMPDIR if present in environment.
22
23 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
24 Remove sandbox_log_file from main() as its no longer used.
25
26 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
27 sandbox_futils.c:
28 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
29 if already exported when sandbox started). Fix get_sandbox_log() and new
30 get_sandbox_debug_log() to not use already exported environment variables if
31 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
32 SB_PATH_MAX fixes.
33
34 * sandbox-1.2.7 (2005/05/12)
35
36 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
37 sandbox_futils.c:
38 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
39
40 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
41 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
42 with '(null)' in it if we did not call sandbox with absolute path.
43
44 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
45 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
46 for the child.
47
48 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
49 Remove global preload_adaptable as it is no longer used.
50
51 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
52 Rewrite environment stuff to only be set when execve'ing the child process
53 to try and avoid issues like bug #91541 that causes sandbox to crash if
54 we set LD_PRELOAD sandbox side already.
55
56 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
57 Move print_sandbox_log() up to make things neater.
58
59 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
60 Remove load_preload_libs(), as its not used anymore.
61
62 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
63 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
64
65 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
66 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
67
68 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
69 Remove ld.so.preload crap - we are not going to use it again.
70
71 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
72 Fix typo in code that checks if we got valid group information, causing a
73 segmentation fault, bug #91637.
74
75 * sandbox-1.2.6 (2005/05/10)
76
77 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
78 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
79 for some odd reason, bug #91541.
80
81 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
82 Fix typo (sizeof -> strlen).
83
84 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
85 rewrote the sbcontext caching code so it accounts for env changes since lib
86 initialization.
87
88 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
89 We create libctest.c via configure, so no need to keep it around. Do some
90 cleanup related to libctest.c and libctest during configure.
91
92 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
93 Add rename support of symlinks pointing to protected files/directories.
94
95 * sandbox-1.2.5 (2005/05/04)
96
97 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
98 sandbox.bashrc:
99 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
100 already set, init of the env vars fails for some reason, so do this later on,
101 and do not warn (bug #91431).
102
103 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
104 sandbox.bashrc:
105 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
106
107 * sandbox-1.2.4 (2005/05/03)
108
109 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
110 Do not init the env entries with each call, as it creates too many calls to
111 lstat, etc. Should speedup things a bit, bug #91040.
112
113 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
114 Add /dev/pty to default write list. Noticed by Morfic.
115
116 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
117 sandbox.h:
118 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
119 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
120
121 * sandbox-1.2.3 (2005/04/29)
122
123 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
124 Do not check for (*&#$(* CXX or F77.
125
126 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
127 Do not append '/' to pathname in filter_path() if it already ends with it.
128
129 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
130 With az's help, clean up autotools to work with cross-compiling.
131
132 * sandbox-1.2.2 (2005/04/28)
133
134 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
135 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
136 have issues; bug #90592.
137
138 * sandbox-1.2.1 (2005/04/23)
139
140 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
141 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
142 Make sure all functions used in libsandbox.c is declared static. Define
143 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
144 linking with its object. Hopefully this will fix bug #90153.
145
146 * sandbox-1.2 (2005/04/23)
147
148 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
149 Allow lchown a symlink in write-allowed path pointing to write-denied
150 target.
151
152 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
153 Also show resolved symlink names in the log.
154
155 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
156 Seems -nostdlib was the problem with the constructor/destructor - remove it
157 from Makefile.am, and change the constructor/destructor names again.
158
159 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
160 Also rename the _init() and _fini() declarations.
161
162 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
163 Fixup the constructor/destructor function names again (they should be _init()
164 and _fini() it seems, and not being called caused sandbox_lib_path to be
165 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
166 Add both the path in given SANDBOX_x variable, as well as its symlink
167 resolved path in init_env_entries(). Modify filter_path() to be able to
168 resolve paths without resolving symlinks, as well as to be able to resolve
169 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
170 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
171 for bug #31019 cause access violations if we try to remove a symlink that is
172 not in protected path, but points to a protected path. Fix a memory leak in
173 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
174 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
175 (pid_string was uninitialized). General syntax cleanups.
176
177 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
178 infamous "pids file is not a regular file" w/out newline bug.
179
180 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
181 Correct libc_version path detection, since it was screwing up if libdir !=
182 "/lib/".
183
184 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
185 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
186
187 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
188 Fix symbols.in not added to dist.
189
190 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
191 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
192 White space fixes.
193
194 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
195 configure.in, getcwd.c, libsandbox.c, symbols.in:
196 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
197 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
198 for glibc and other libc's that use this. Update libsandbox.c to use these
199 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
200 process unset it.
201
202 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
203 killed off _init and _fini in favor of
204 void __attribute__ ((constructor)) init_func and
205 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
206
207 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
208 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
209 having the hick-ups.
210
211 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
212 Makefile.am: Fixed compilation.
213
214 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
215 Gutted the bugger so it stops checking for a c++ and fortran compiler.
216 Do *not* regenerate aclocal.m4 for making a release until a better
217 solution is created.
218
219 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
220 Removal of more hardcoded paths.
221
222 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
223 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
224
225 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
226 Sandbox is now autotooled, create-localdecls needs to be killed and the code
227 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
228 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
229 To get to a point of testing, automake && autoconf; created requisite files w/
230 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
231 /lib and /usr/lib/portage/bin.
232
233 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
234 closing out bug #70225, potential overflow of the sandbox_pids_file var.
235
236 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
237 (think it was at least) allows intermixing of code and data segments. bug #70351
238 should be fixed by this.
239
240 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
241 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
242
243 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
244 Seth Robertson that tracked down all adjuct flags for read operations that
245 do not invoke a write operation.
246
247 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
248 Another fix from jstubbs regarding a free() on a stack variable for the
249 environment -- tracking now prevents extraneous free()'s segfault.
250
251 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
252 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
253 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
254 Also remove the errno = ESUCCESS settings as documentation points out that
255 a library isn't allowed to do that.
256
257 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
258 file_security_check() function to check random potential exploits on files
259 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
260 the 'system-crippling' exploits (bug 21923) and catches a few other
261 potential problems.
262
263 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
264 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
265
266 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
267 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
268 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
269
270 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
271 Fix permissions and group of pids file and logs. Permissions should be 0664
272 and group should be 'portage'. Bug #34260.
273
274 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
275 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
276 to the real execve (in our execve wrapper). Seems that on some arches (sparc
277 among others) do not allow us to tamper with the readonly copy passed to
278 execve, so pass our own copy of the environment. Bug #42290.
279
280 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
281 Changed tail to head and added a notice about duration of glibc check.
282
283 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
284 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
285 as there isn't a guarentee that it is dynamic.
286
287 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
288 If 'file' passed to before_syscall(const char *func, const char *file) is
289 invalid, we should set errno to ENOENT, and not EINVAL. This should
290 close bug #32238.
291
292 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
293 Fix a bug that occurs mainly on 64bit arch, where the file passed to
294 the functions we wrap, is invalid, and then cause canonicalize to pass
295 garbage to before_syscall(), thanks to great detective work from
296 Andrea Luzzardi <al@sig11.org> (bug #29846).
297
298 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
299 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
300
301 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
302 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
303 only checked the destination patch, and not the source, so we could move
304 a protected file to a unprotected directory, and then delete/modify it.
305 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
306
307 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
308 Added python2.3 to the predict section/variable.
309
310 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
311 sandbox.h, sandbox_futils.c :
312 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
313 it is not set, it will revert to its old value.
314
315 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
316 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
317 rather than failing with a violation, bug #29748.
318
319 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
320 Fix canonicalize() to ignore calls with path = "".
321
322 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
323 sandbox_futils.c, canonicalize.c :
324 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
325 call handled strings larger than PATH_MAX (bug #21766). It however does not
326 work the same on 2.4 kernels.
327
328 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
329 do not need the system call. We use the default getcwd() function via a
330 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
331 means the current directory was removed, OR that the the system call for
332 getcwd failed (curious is that it do not fail and return NULL or set
333 errno, but rather just truncate the retured directory - usually from the
334 start), and if so, we use the generic getcwd() function (__egetcwd). Note
335 that we do not use the generic version all the time, as it calls lstat()
336 a great number of times, and performance degrade much.
337
338 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
339 libsandbox.c :
340 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
341
342 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
343 create-localdecls :
344 When checking path names of files accessed, we need to canonicalize it, else
345 it may be a symlink in a 'write allowed' directory pointing to a file in a
346 directory we should not have write access to.
347
348 With something like coreutils-5.0, we have two problems:
349 1) One of the tests checks if getcwd() can return a path longer than
350 PATH_MAX. This test then tries to create a dir which even while
351 created local (mkdir("conftest2")), it ends up being resolved with
352 a name that is much larger than PATH_MAX. The problem now is that
353 canonicalize() have undefined behaviour when the path was too long
354 (returned wrongly truncated paths, etc), and pass the wrong path to
355 before_syscall() (causing the bogus sandbox violations).
356 2) The ecanonicalize() function we used, along with the canonicalize()
357 function did not support longer than PATH_MAX. This is partly a
358 cause for 1), but the error checking (rather lack of it) of calls
359 to erealpath() in canonicalize() was the prime reason for 1).
360
361 As we do not use this canonicalized name to call the function, we resolve this
362 by fixing canonicalize() to do better error checking, and ecanonicalize() as
363 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
364 While they will resolve paths properly now, and can check if a write/read is
365 allowed, the functions called from the sandboxed environment will still work
366 as expected.
367
368 This should resolve bug #21766.
369
370 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
371 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
372 it (bug #16298).
373
374 Problem is that for some reason locale fopen's locale.alias with mode "rm".
375
376 -------------------------------------------------------
377 nosferatu root # grep fopen locale.log
378 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
379 nosferatu root #
380 --------------------------------------------------------
381
382 I checked the source of locale, but it have fopen with mode 'r', so
383 not sure where the "rm" mode comes from. Anyhow, changed the check in
384 before_syscall_open_char() to also see mode "rm" as readonly.
385
386 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
387
388 Add glibc-2.3 support.
389
390 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
391
392 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
393 operations releated to preload, as well as only try to modify ld.so.preload
394 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
395 not using ld.so.preload. Fix to not write this instance of sandbox's pid
396 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
397
398 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
399
400 Changed the LD to CC for hppa.
401
402 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
403
404 Killed the previous changes I made.
405
406 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
407
408 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
409
410 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
411
412 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
413
414 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
415
416 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
417 for this fix.
418
419 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
420
421 sandbox_futils defined a dirname() function that was masking the same
422 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
423 '/usr/lib/portage/bi/'). Fixed function to return expected results and
424 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
425 11231.
426
427 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
428
429 Fix a segfault in libsandbox.c if canonicalize() was called with
430 first parameter = NULL.
431
432 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
433
434 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
435 cleanup() for this.
436
437 Change cleanup() in sandbox.c not to exit with fail status if
438 the pidsfile is missing. We really should still display sandbox
439 violations if they occured.
440
441 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
442
443 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
444 the last sandbox running.
445
446 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
447
448 Major cleanups to mainly libsandbox.c again.
449
450 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
451
452 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
453 parties involved should please contact me so that we can fix it.
454
455 Add opendir wrapper to libsandbox.c.
456
457 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
458
459 Do some more cleanups to ecanonicalize(), as it dropped filenames in
460 rare cases (after my symlink cleanups), and caused glibc to bork.
461 These fixes went into canonicalize.c.
462
463 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
464
465 Fix spawn_shell() and main() in sandbox.c to properly return fail
466 status.
467
468 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
469
470 The new canonicalize() function in libsandbox.c also resolved symlinks,
471 which caused on cleaning sandbox errors if the symlink pointed to a
472 file in the live root. Ripped out canonicalize() and realpath() from
473 glibc; removed the symlink stuff, and changed them to ecanonicalize()
474 and erealpath().
475
476 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
477
478 Ripped out all the wrappers, and implemented those of InstallWatch.
479 Losts of cleanups and bugfixes. Implement a execve that forces
480 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
481 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
482 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
483 parts; it now have an install target.
484
485 Reformat the whole thing to look somewhat like the reworked sandbox.c
486 and new sandbox.h and sandbox_futils.c from:
487
488 Brad House <brad@mainstreetsoftworks.com>.
489
490 Additional Copyrights now due to the InstallWatch code:
