5 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
6 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
7
8 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
9 Add wrapper for access() function, bug #85413.
10
11 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
12 Use generic getcwd() implementation from uclibc - should be more portable
13 and looks a bit cleaner.
14
15 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
16 Make sure our true_* pointers are initialized to NULL, and that we check for
17 all references that they are valid.
18
19 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
20 Be default we will fail if the path name we try to canonicalize is too long.
21 This however could cause issues with some things (bug #94630 and #21766), so
22 if fail_nametoolong == 0, canonicalize() will return a null length string and
23 do not fail.
24
25 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
26 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
27 make sure we re-export the new TMPDIR environment variable.
28
29 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
30 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
31 by Marcus D. Hanwell <cryos@gentoo.org>.
32
33 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
34 Add /dev/console to write list, bug #38588.
35
36 * sandbox-1.2.8 (2005/05/13)
37
38 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
39 sandbox.h, sandbox_futils.c:
40 General cleanups.
41
42 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
43 sandbox.h:
44 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
45
46 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
47 sandbox.h, sandbox_futils.c:
48 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
49 to use TMPDIR if present in environment.
50
51 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
52 Remove sandbox_log_file from main() as its no longer used.
53
54 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
55 sandbox_futils.c:
56 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
57 if already exported when sandbox started). Fix get_sandbox_log() and new
58 get_sandbox_debug_log() to not use already exported environment variables if
59 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
60 SB_PATH_MAX fixes.
61
62 * sandbox-1.2.7 (2005/05/12)
63
64 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
65 sandbox_futils.c:
66 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
67
68 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
69 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
70 with '(null)' in it if we did not call sandbox with absolute path.
71
72 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
73 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
74 for the child.
75
76 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
77 Remove global preload_adaptable as it is no longer used.
78
79 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
80 Rewrite environment stuff to only be set when execve'ing the child process
81 to try and avoid issues like bug #91541 that causes sandbox to crash if
82 we set LD_PRELOAD sandbox side already.
83
84 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
85 Move print_sandbox_log() up to make things neater.
86
87 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
88 Remove load_preload_libs(), as its not used anymore.
89
90 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
91 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
92
93 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
94 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
95
96 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
97 Remove ld.so.preload crap - we are not going to use it again.
98
99 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
100 Fix typo in code that checks if we got valid group information, causing a
101 segmentation fault, bug #91637.
102
103 * sandbox-1.2.6 (2005/05/10)
104
105 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
106 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
107 for some odd reason, bug #91541.
108
109 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
110 Fix typo (sizeof -> strlen).
111
112 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
113 rewrote the sbcontext caching code so it accounts for env changes since lib
114 initialization.
115
116 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
117 We create libctest.c via configure, so no need to keep it around. Do some
118 cleanup related to libctest.c and libctest during configure.
119
120 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
121 Add rename support of symlinks pointing to protected files/directories.
122
123 * sandbox-1.2.5 (2005/05/04)
124
125 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
126 sandbox.bashrc:
127 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
128 already set, init of the env vars fails for some reason, so do this later on,
129 and do not warn (bug #91431).
130
131 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
132 sandbox.bashrc:
133 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
134
135 * sandbox-1.2.4 (2005/05/03)
136
137 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
138 Do not init the env entries with each call, as it creates too many calls to
139 lstat, etc. Should speedup things a bit, bug #91040.
140
141 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
142 Add /dev/pty to default write list. Noticed by Morfic.
143
144 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
145 sandbox.h:
146 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
147 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
148
149 * sandbox-1.2.3 (2005/04/29)
150
151 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
152 Do not check for (*&#$(* CXX or F77.
153
154 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
155 Do not append '/' to pathname in filter_path() if it already ends with it.
156
157 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
158 With az's help, clean up autotools to work with cross-compiling.
159
160 * sandbox-1.2.2 (2005/04/28)
161
162 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
163 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
164 have issues; bug #90592.
165
166 * sandbox-1.2.1 (2005/04/23)
167
168 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
169 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
170 Make sure all functions used in libsandbox.c is declared static. Define
171 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
172 linking with its object. Hopefully this will fix bug #90153.
173
174 * sandbox-1.2 (2005/04/23)
175
176 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
177 Allow lchown a symlink in write-allowed path pointing to write-denied
178 target.
179
180 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
181 Also show resolved symlink names in the log.
182
183 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
184 Seems -nostdlib was the problem with the constructor/destructor - remove it
185 from Makefile.am, and change the constructor/destructor names again.
186
187 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
188 Also rename the _init() and _fini() declarations.
189
190 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
191 Fixup the constructor/destructor function names again (they should be _init()
192 and _fini() it seems, and not being called caused sandbox_lib_path to be
193 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
194 Add both the path in given SANDBOX_x variable, as well as its symlink
195 resolved path in init_env_entries(). Modify filter_path() to be able to
196 resolve paths without resolving symlinks, as well as to be able to resolve
197 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
198 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
199 for bug #31019 cause access violations if we try to remove a symlink that is
200 not in protected path, but points to a protected path. Fix a memory leak in
201 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
202 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
203 (pid_string was uninitialized). General syntax cleanups.
204
205 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
206 infamous "pids file is not a regular file" w/out newline bug.
207
208 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
209 Correct libc_version path detection, since it was screwing up if libdir !=
210 "/lib/".
211
212 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
213 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
214
215 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
216 Fix symbols.in not added to dist.
217
218 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
219 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
220 White space fixes.
221
222 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
223 configure.in, getcwd.c, libsandbox.c, symbols.in:
224 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
225 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
226 for glibc and other libc's that use this. Update libsandbox.c to use these
227 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
228 process unset it.
229
230 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
231 killed off _init and _fini in favor of
232 void __attribute__ ((constructor)) init_func and
233 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
234
235 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
236 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
237 having the hick-ups.
238
239 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
240 Makefile.am: Fixed compilation.
241
242 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
243 Gutted the bugger so it stops checking for a c++ and fortran compiler.
244 Do *not* regenerate aclocal.m4 for making a release until a better
245 solution is created.
246
247 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
248 Removal of more hardcoded paths.
249
250 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
251 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
252
253 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
254 Sandbox is now autotooled, create-localdecls needs to be killed and the code
255 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
256 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
257 To get to a point of testing, automake && autoconf; created requisite files w/
258 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
259 /lib and /usr/lib/portage/bin.
260
261 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
262 closing out bug #70225, potential overflow of the sandbox_pids_file var.
263
264 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
265 (think it was at least) allows intermixing of code and data segments. bug #70351
266 should be fixed by this.
267
268 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
269 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
270
271 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
272 Seth Robertson that tracked down all adjuct flags for read operations that
273 do not invoke a write operation.
274
275 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
276 Another fix from jstubbs regarding a free() on a stack variable for the
277 environment -- tracking now prevents extraneous free()'s segfault.
278
279 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
280 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
281 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
282 Also remove the errno = ESUCCESS settings as documentation points out that
283 a library isn't allowed to do that.
284
285 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
286 file_security_check() function to check random potential exploits on files
287 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
288 the 'system-crippling' exploits (bug 21923) and catches a few other
289 potential problems.
290
291 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
292 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
293
294 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
295 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
296 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
297
298 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
299 Fix permissions and group of pids file and logs. Permissions should be 0664
300 and group should be 'portage'. Bug #34260.
301
302 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
303 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
304 to the real execve (in our execve wrapper). Seems that on some arches (sparc
305 among others) do not allow us to tamper with the readonly copy passed to
306 execve, so pass our own copy of the environment. Bug #42290.
307
308 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
309 Changed tail to head and added a notice about duration of glibc check.
310
311 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
312 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
313 as there isn't a guarentee that it is dynamic.
314
315 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
316 If 'file' passed to before_syscall(const char *func, const char *file) is
317 invalid, we should set errno to ENOENT, and not EINVAL. This should
318 close bug #32238.
319
320 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
321 Fix a bug that occurs mainly on 64bit arch, where the file passed to
322 the functions we wrap, is invalid, and then cause canonicalize to pass
323 garbage to before_syscall(), thanks to great detective work from
324 Andrea Luzzardi <al@sig11.org> (bug #29846).
325
326 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
327 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
328
329 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
330 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
331 only checked the destination patch, and not the source, so we could move
332 a protected file to a unprotected directory, and then delete/modify it.
333 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
334
335 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
336 Added python2.3 to the predict section/variable.
337
338 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
339 sandbox.h, sandbox_futils.c :
340 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
341 it is not set, it will revert to its old value.
342
343 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
344 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
345 rather than failing with a violation, bug #29748.
346
347 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
348 Fix canonicalize() to ignore calls with path = "".
349
350 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
351 sandbox_futils.c, canonicalize.c :
352 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
353 call handled strings larger than PATH_MAX (bug #21766). It however does not
354 work the same on 2.4 kernels.
355
356 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
357 do not need the system call. We use the default getcwd() function via a
358 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
359 means the current directory was removed, OR that the the system call for
360 getcwd failed (curious is that it do not fail and return NULL or set
361 errno, but rather just truncate the retured directory - usually from the
362 start), and if so, we use the generic getcwd() function (__egetcwd). Note
363 that we do not use the generic version all the time, as it calls lstat()
364 a great number of times, and performance degrade much.
365
366 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
367 libsandbox.c :
368 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
369
370 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
371 create-localdecls :
372 When checking path names of files accessed, we need to canonicalize it, else
373 it may be a symlink in a 'write allowed' directory pointing to a file in a
374 directory we should not have write access to.
375
376 With something like coreutils-5.0, we have two problems:
377 1) One of the tests checks if getcwd() can return a path longer than
378 PATH_MAX. This test then tries to create a dir which even while
379 created local (mkdir("conftest2")), it ends up being resolved with
380 a name that is much larger than PATH_MAX. The problem now is that
381 canonicalize() have undefined behaviour when the path was too long
382 (returned wrongly truncated paths, etc), and pass the wrong path to
383 before_syscall() (causing the bogus sandbox violations).
384 2) The ecanonicalize() function we used, along with the canonicalize()
385 function did not support longer than PATH_MAX. This is partly a
386 cause for 1), but the error checking (rather lack of it) of calls
387 to erealpath() in canonicalize() was the prime reason for 1).
388
389 As we do not use this canonicalized name to call the function, we resolve this
390 by fixing canonicalize() to do better error checking, and ecanonicalize() as
391 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
392 While they will resolve paths properly now, and can check if a write/read is
393 allowed, the functions called from the sandboxed environment will still work
394 as expected.
395
396 This should resolve bug #21766.
397
398 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
399 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
400 it (bug #16298).
401
402 Problem is that for some reason locale fopen's locale.alias with mode "rm".
403
404 -------------------------------------------------------
405 nosferatu root # grep fopen locale.log
406 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
407 nosferatu root #
408 --------------------------------------------------------
409
410 I checked the source of locale, but it have fopen with mode 'r', so
411 not sure where the "rm" mode comes from. Anyhow, changed the check in
412 before_syscall_open_char() to also see mode "rm" as readonly.
413
414 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
415
416 Add glibc-2.3 support.
417
418 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
419
420 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
421 operations releated to preload, as well as only try to modify ld.so.preload
422 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
423 not using ld.so.preload. Fix to not write this instance of sandbox's pid
424 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
425
426 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
427
428 Changed the LD to CC for hppa.
429
430 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
431
432 Killed the previous changes I made.
433
434 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
435
436 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
437
438 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
439
440 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
441
442 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
443
444 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
445 for this fix.
446
447 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
448
449 sandbox_futils defined a dirname() function that was masking the same
450 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
451 '/usr/lib/portage/bi/'). Fixed function to return expected results and
452 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
453 11231.
454
455 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
456
457 Fix a segfault in libsandbox.c if canonicalize() was called with
458 first parameter = NULL.
459
460 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
461
462 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
463 cleanup() for this.
464
465 Change cleanup() in sandbox.c not to exit with fail status if
466 the pidsfile is missing. We really should still display sandbox
467 violations if they occured.
468
469 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
470
471 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
472 the last sandbox running.
473
474 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
475
476 Major cleanups to mainly libsandbox.c again.
477
478 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
479
480 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
481 parties involved should please contact me so that we can fix it.
482
483 Add opendir wrapper to libsandbox.c.
484
485 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
486
487 Do some more cleanups to ecanonicalize(), as it dropped filenames in
488 rare cases (after my symlink cleanups), and caused glibc to bork.
489 These fixes went into canonicalize.c.
490
491 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
492
493 Fix spawn_shell() and main() in sandbox.c to properly return fail
494 status.
495
496 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
497
498 The new canonicalize() function in libsandbox.c also resolved symlinks,
499 which caused on cleaning sandbox errors if the symlink pointed to a
500 file in the live root. Ripped out canonicalize() and realpath() from
501 glibc; removed the symlink stuff, and changed them to ecanonicalize()
502 and erealpath().
503
504 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
505
506 Ripped out all the wrappers, and implemented those of InstallWatch.
507 Losts of cleanups and bugfixes. Implement a execve that forces
508 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
509 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
510 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
511 parts; it now have an install target.
512
513 Reformat the whole thing to look somewhat like the reworked sandbox.c
514 and new sandbox.h and sandbox_futils.c from:
515
516 Brad House <brad@mainstreetsoftworks.com>.
517
518 Additional Copyrights now due to the InstallWatch code:
