4
5 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
6 Make sure our true_* pointers are initialized to NULL, and that we check for
7 all references that they are valid.
8
9 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
10 Be default we will fail if the path name we try to canonicalize is too long.
11 This however could cause issues with some things (bug #94630 and #21766), so
12 if fail_nametoolong == 0, canonicalize() will return a null length string and
13 do not fail.
14
15 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
16 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
17 make sure we re-export the new TMPDIR environment variable.
18
19 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
20 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
21 by Marcus D. Hanwell <cryos@gentoo.org>.
22
23 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
24 Add /dev/console to write list, bug #38588.
25
26 * sandbox-1.2.8 (2005/05/13)
27
28 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
29 sandbox.h, sandbox_futils.c:
30 General cleanups.
31
32 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
33 sandbox.h:
34 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
35
36 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
37 sandbox.h, sandbox_futils.c:
38 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
39 to use TMPDIR if present in environment.
40
41 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
42 Remove sandbox_log_file from main() as its no longer used.
43
44 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
45 sandbox_futils.c:
46 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
47 if already exported when sandbox started). Fix get_sandbox_log() and new
48 get_sandbox_debug_log() to not use already exported environment variables if
49 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
50 SB_PATH_MAX fixes.
51
52 * sandbox-1.2.7 (2005/05/12)
53
54 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
55 sandbox_futils.c:
56 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
57
58 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
59 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
60 with '(null)' in it if we did not call sandbox with absolute path.
61
62 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
63 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
64 for the child.
65
66 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
67 Remove global preload_adaptable as it is no longer used.
68
69 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
70 Rewrite environment stuff to only be set when execve'ing the child process
71 to try and avoid issues like bug #91541 that causes sandbox to crash if
72 we set LD_PRELOAD sandbox side already.
73
74 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
75 Move print_sandbox_log() up to make things neater.
76
77 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
78 Remove load_preload_libs(), as its not used anymore.
79
80 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
81 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
82
83 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
84 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
85
86 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
87 Remove ld.so.preload crap - we are not going to use it again.
88
89 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
90 Fix typo in code that checks if we got valid group information, causing a
91 segmentation fault, bug #91637.
92
93 * sandbox-1.2.6 (2005/05/10)
94
95 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
96 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
97 for some odd reason, bug #91541.
98
99 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
100 Fix typo (sizeof -> strlen).
101
102 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
103 rewrote the sbcontext caching code so it accounts for env changes since lib
104 initialization.
105
106 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
107 We create libctest.c via configure, so no need to keep it around. Do some
108 cleanup related to libctest.c and libctest during configure.
109
110 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
111 Add rename support of symlinks pointing to protected files/directories.
112
113 * sandbox-1.2.5 (2005/05/04)
114
115 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
116 sandbox.bashrc:
117 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
118 already set, init of the env vars fails for some reason, so do this later on,
119 and do not warn (bug #91431).
120
121 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
122 sandbox.bashrc:
123 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
124
125 * sandbox-1.2.4 (2005/05/03)
126
127 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
128 Do not init the env entries with each call, as it creates too many calls to
129 lstat, etc. Should speedup things a bit, bug #91040.
130
131 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
132 Add /dev/pty to default write list. Noticed by Morfic.
133
134 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
135 sandbox.h:
136 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
137 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
138
139 * sandbox-1.2.3 (2005/04/29)
140
141 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
142 Do not check for (*&#$(* CXX or F77.
143
144 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
145 Do not append '/' to pathname in filter_path() if it already ends with it.
146
147 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
148 With az's help, clean up autotools to work with cross-compiling.
149
150 * sandbox-1.2.2 (2005/04/28)
151
152 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
153 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
154 have issues; bug #90592.
155
156 * sandbox-1.2.1 (2005/04/23)
157
158 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
159 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
160 Make sure all functions used in libsandbox.c is declared static. Define
161 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
162 linking with its object. Hopefully this will fix bug #90153.
163
164 * sandbox-1.2 (2005/04/23)
165
166 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
167 Allow lchown a symlink in write-allowed path pointing to write-denied
168 target.
169
170 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
171 Also show resolved symlink names in the log.
172
173 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
174 Seems -nostdlib was the problem with the constructor/destructor - remove it
175 from Makefile.am, and change the constructor/destructor names again.
176
177 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
178 Also rename the _init() and _fini() declarations.
179
180 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
181 Fixup the constructor/destructor function names again (they should be _init()
182 and _fini() it seems, and not being called caused sandbox_lib_path to be
183 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
184 Add both the path in given SANDBOX_x variable, as well as its symlink
185 resolved path in init_env_entries(). Modify filter_path() to be able to
186 resolve paths without resolving symlinks, as well as to be able to resolve
187 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
188 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
189 for bug #31019 cause access violations if we try to remove a symlink that is
190 not in protected path, but points to a protected path. Fix a memory leak in
191 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
192 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
193 (pid_string was uninitialized). General syntax cleanups.
194
195 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
196 infamous "pids file is not a regular file" w/out newline bug.
197
198 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
199 Correct libc_version path detection, since it was screwing up if libdir !=
200 "/lib/".
201
202 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
203 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
204
205 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
206 Fix symbols.in not added to dist.
207
208 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
209 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
210 White space fixes.
211
212 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
213 configure.in, getcwd.c, libsandbox.c, symbols.in:
214 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
215 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
216 for glibc and other libc's that use this. Update libsandbox.c to use these
217 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
218 process unset it.
219
220 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
221 killed off _init and _fini in favor of
222 void __attribute__ ((constructor)) init_func and
223 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
224
225 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
226 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
227 having the hick-ups.
228
229 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
230 Makefile.am: Fixed compilation.
231
232 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
233 Gutted the bugger so it stops checking for a c++ and fortran compiler.
234 Do *not* regenerate aclocal.m4 for making a release until a better
235 solution is created.
236
237 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
238 Removal of more hardcoded paths.
239
240 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
241 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
242
243 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
244 Sandbox is now autotooled, create-localdecls needs to be killed and the code
245 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
246 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
247 To get to a point of testing, automake && autoconf; created requisite files w/
248 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
249 /lib and /usr/lib/portage/bin.
250
251 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
252 closing out bug #70225, potential overflow of the sandbox_pids_file var.
253
254 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
255 (think it was at least) allows intermixing of code and data segments. bug #70351
256 should be fixed by this.
257
258 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
259 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
260
261 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
262 Seth Robertson that tracked down all adjuct flags for read operations that
263 do not invoke a write operation.
264
265 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
266 Another fix from jstubbs regarding a free() on a stack variable for the
267 environment -- tracking now prevents extraneous free()'s segfault.
268
269 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
270 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
271 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
272 Also remove the errno = ESUCCESS settings as documentation points out that
273 a library isn't allowed to do that.
274
275 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
276 file_security_check() function to check random potential exploits on files
277 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
278 the 'system-crippling' exploits (bug 21923) and catches a few other
279 potential problems.
280
281 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
282 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
283
284 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
285 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
286 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
287
288 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
289 Fix permissions and group of pids file and logs. Permissions should be 0664
290 and group should be 'portage'. Bug #34260.
291
292 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
293 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
294 to the real execve (in our execve wrapper). Seems that on some arches (sparc
295 among others) do not allow us to tamper with the readonly copy passed to
296 execve, so pass our own copy of the environment. Bug #42290.
297
298 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
299 Changed tail to head and added a notice about duration of glibc check.
300
301 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
302 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
303 as there isn't a guarentee that it is dynamic.
304
305 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
306 If 'file' passed to before_syscall(const char *func, const char *file) is
307 invalid, we should set errno to ENOENT, and not EINVAL. This should
308 close bug #32238.
309
310 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
311 Fix a bug that occurs mainly on 64bit arch, where the file passed to
312 the functions we wrap, is invalid, and then cause canonicalize to pass
313 garbage to before_syscall(), thanks to great detective work from
314 Andrea Luzzardi <al@sig11.org> (bug #29846).
315
316 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
317 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
318
319 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
320 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
321 only checked the destination patch, and not the source, so we could move
322 a protected file to a unprotected directory, and then delete/modify it.
323 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
324
325 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
326 Added python2.3 to the predict section/variable.
327
328 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
329 sandbox.h, sandbox_futils.c :
330 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
331 it is not set, it will revert to its old value.
332
333 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
334 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
335 rather than failing with a violation, bug #29748.
336
337 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
338 Fix canonicalize() to ignore calls with path = "".
339
340 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
341 sandbox_futils.c, canonicalize.c :
342 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
343 call handled strings larger than PATH_MAX (bug #21766). It however does not
344 work the same on 2.4 kernels.
345
346 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
347 do not need the system call. We use the default getcwd() function via a
348 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
349 means the current directory was removed, OR that the the system call for
350 getcwd failed (curious is that it do not fail and return NULL or set
351 errno, but rather just truncate the retured directory - usually from the
352 start), and if so, we use the generic getcwd() function (__egetcwd). Note
353 that we do not use the generic version all the time, as it calls lstat()
354 a great number of times, and performance degrade much.
355
356 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
357 libsandbox.c :
358 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
359
360 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
361 create-localdecls :
362 When checking path names of files accessed, we need to canonicalize it, else
363 it may be a symlink in a 'write allowed' directory pointing to a file in a
364 directory we should not have write access to.
365
366 With something like coreutils-5.0, we have two problems:
367 1) One of the tests checks if getcwd() can return a path longer than
368 PATH_MAX. This test then tries to create a dir which even while
369 created local (mkdir("conftest2")), it ends up being resolved with
370 a name that is much larger than PATH_MAX. The problem now is that
371 canonicalize() have undefined behaviour when the path was too long
372 (returned wrongly truncated paths, etc), and pass the wrong path to
373 before_syscall() (causing the bogus sandbox violations).
374 2) The ecanonicalize() function we used, along with the canonicalize()
375 function did not support longer than PATH_MAX. This is partly a
376 cause for 1), but the error checking (rather lack of it) of calls
377 to erealpath() in canonicalize() was the prime reason for 1).
378
379 As we do not use this canonicalized name to call the function, we resolve this
380 by fixing canonicalize() to do better error checking, and ecanonicalize() as
381 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
382 While they will resolve paths properly now, and can check if a write/read is
383 allowed, the functions called from the sandboxed environment will still work
384 as expected.
385
386 This should resolve bug #21766.
387
388 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
389 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
390 it (bug #16298).
391
392 Problem is that for some reason locale fopen's locale.alias with mode "rm".
393

400 I checked the source of locale, but it have fopen with mode 'r', so
401 not sure where the "rm" mode comes from. Anyhow, changed the check in
402 before_syscall_open_char() to also see mode "rm" as readonly.

404 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
405
406 Add glibc-2.3 support.
407
408 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
409
410 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
411 operations releated to preload, as well as only try to modify ld.so.preload
412 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
413 not using ld.so.preload. Fix to not write this instance of sandbox's pid
414 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
415
416 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
417
418 Changed the LD to CC for hppa.
419
420 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
421
422 Killed the previous changes I made.
423
424 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
425
426 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
427
428 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
429
430 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
431
432 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
433
434 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
435 for this fix.
436
437 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
438
439 sandbox_futils defined a dirname() function that was masking the same
440 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
441 '/usr/lib/portage/bi/'). Fixed function to return expected results and
442 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
443 11231.
444
445 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
446
447 Fix a segfault in libsandbox.c if canonicalize() was called with
448 first parameter = NULL.
449
450 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
451
452 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
453 cleanup() for this.
454
455 Change cleanup() in sandbox.c not to exit with fail status if
456 the pidsfile is missing. We really should still display sandbox
457 violations if they occured.
458
459 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
460
461 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
462 the last sandbox running.
463
464 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
465
466 Major cleanups to mainly libsandbox.c again.
467
468 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
469
470 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
471 parties involved should please contact me so that we can fix it.
472
473 Add opendir wrapper to libsandbox.c.
474
475 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
476
477 Do some more cleanups to ecanonicalize(), as it dropped filenames in
478 rare cases (after my symlink cleanups), and caused glibc to bork.
479 These fixes went into canonicalize.c.
480
481 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
482
483 Fix spawn_shell() and main() in sandbox.c to properly return fail
484 status.
485
486 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
487
488 The new canonicalize() function in libsandbox.c also resolved symlinks,
489 which caused on cleaning sandbox errors if the symlink pointed to a
490 file in the live root. Ripped out canonicalize() and realpath() from
491 glibc; removed the symlink stuff, and changed them to ecanonicalize()
492 and erealpath().
493
494 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
495
496 Ripped out all the wrappers, and implemented those of InstallWatch.
497 Losts of cleanups and bugfixes. Implement a execve that forces
498 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
499 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
500 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
501 parts; it now have an install target.
502
503 Reformat the whole thing to look somewhat like the reworked sandbox.c
504 and new sandbox.h and sandbox_futils.c from:
505
506 Brad House <brad@mainstreetsoftworks.com>.
507
508 Additional Copyrights now due to the InstallWatch code:
