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