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