4
5 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
6 sandbox_futils.c, libsandbox.c:
7 Some strncpy/strncat and other cleanups.
8
9 * sandbox-1.2.9 (2005/06/09)
10
11 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
12 Move symlink hack down a bit to try and minimize on the amount of lstat()
13 calls we do.
14
15 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
16 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
17
18 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
19 Add wrapper for access() function, bug #85413.
20
21 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
22 Use generic getcwd() implementation from uclibc - should be more portable
23 and looks a bit cleaner.
24
25 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
26 Make sure our true_* pointers are initialized to NULL, and that we check for
27 all references that they are valid.
28
29 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
30 Be default we will fail if the path name we try to canonicalize is too long.
31 This however could cause issues with some things (bug #94630 and #21766), so
32 if fail_nametoolong == 0, canonicalize() will return a null length string and
33 do not fail.
34
35 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
36 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
37 make sure we re-export the new TMPDIR environment variable.
38
39 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
40 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
41 by Marcus D. Hanwell <cryos@gentoo.org>.
42
43 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
44 Add /dev/console to write list, bug #38588.
45
46 * sandbox-1.2.8 (2005/05/13)
47
48 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
49 sandbox.h, sandbox_futils.c:
50 General cleanups.
51
52 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
53 sandbox.h:
54 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
55
56 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
57 sandbox.h, sandbox_futils.c:
58 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
59 to use TMPDIR if present in environment.
60
61 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
62 Remove sandbox_log_file from main() as its no longer used.
63
64 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
65 sandbox_futils.c:
66 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
67 if already exported when sandbox started). Fix get_sandbox_log() and new
68 get_sandbox_debug_log() to not use already exported environment variables if
69 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
70 SB_PATH_MAX fixes.
71
72 * sandbox-1.2.7 (2005/05/12)
73
74 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
75 sandbox_futils.c:
76 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
77
78 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
79 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
80 with '(null)' in it if we did not call sandbox with absolute path.
81
82 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
83 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
84 for the child.
85
86 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
87 Remove global preload_adaptable as it is no longer used.
88
89 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
90 Rewrite environment stuff to only be set when execve'ing the child process
91 to try and avoid issues like bug #91541 that causes sandbox to crash if
92 we set LD_PRELOAD sandbox side already.
93
94 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
95 Move print_sandbox_log() up to make things neater.
96
97 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
98 Remove load_preload_libs(), as its not used anymore.
99
100 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
101 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
102
103 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
104 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
105
106 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
107 Remove ld.so.preload crap - we are not going to use it again.
108
109 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
110 Fix typo in code that checks if we got valid group information, causing a
111 segmentation fault, bug #91637.
112
113 * sandbox-1.2.6 (2005/05/10)
114
115 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
116 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
117 for some odd reason, bug #91541.
118
119 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
120 Fix typo (sizeof -> strlen).
121
122 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
123 rewrote the sbcontext caching code so it accounts for env changes since lib
124 initialization.
125
126 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
127 We create libctest.c via configure, so no need to keep it around. Do some
128 cleanup related to libctest.c and libctest during configure.
129
130 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
131 Add rename support of symlinks pointing to protected files/directories.
132
133 * sandbox-1.2.5 (2005/05/04)
134
135 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
136 sandbox.bashrc:
137 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
138 already set, init of the env vars fails for some reason, so do this later on,
139 and do not warn (bug #91431).
140
141 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
142 sandbox.bashrc:
143 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
144
145 * sandbox-1.2.4 (2005/05/03)
146
147 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
148 Do not init the env entries with each call, as it creates too many calls to
149 lstat, etc. Should speedup things a bit, bug #91040.
150
151 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
152 Add /dev/pty to default write list. Noticed by Morfic.
153
154 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
155 sandbox.h:
156 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
157 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
158
159 * sandbox-1.2.3 (2005/04/29)
160
161 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
162 Do not check for (*&#$(* CXX or F77.
163
164 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
165 Do not append '/' to pathname in filter_path() if it already ends with it.
166
167 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
168 With az's help, clean up autotools to work with cross-compiling.
169
170 * sandbox-1.2.2 (2005/04/28)
171
172 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
173 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
174 have issues; bug #90592.
175
176 * sandbox-1.2.1 (2005/04/23)
177
178 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
179 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
180 Make sure all functions used in libsandbox.c is declared static. Define
181 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
182 linking with its object. Hopefully this will fix bug #90153.
183
184 * sandbox-1.2 (2005/04/23)
185
186 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
187 Allow lchown a symlink in write-allowed path pointing to write-denied
188 target.
189
190 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
191 Also show resolved symlink names in the log.
192
193 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
194 Seems -nostdlib was the problem with the constructor/destructor - remove it
195 from Makefile.am, and change the constructor/destructor names again.
196
197 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
198 Also rename the _init() and _fini() declarations.
199
200 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
201 Fixup the constructor/destructor function names again (they should be _init()
202 and _fini() it seems, and not being called caused sandbox_lib_path to be
203 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
204 Add both the path in given SANDBOX_x variable, as well as its symlink
205 resolved path in init_env_entries(). Modify filter_path() to be able to
206 resolve paths without resolving symlinks, as well as to be able to resolve
207 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
208 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
209 for bug #31019 cause access violations if we try to remove a symlink that is
210 not in protected path, but points to a protected path. Fix a memory leak in
211 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
212 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
213 (pid_string was uninitialized). General syntax cleanups.
214
215 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
216 infamous "pids file is not a regular file" w/out newline bug.
217
218 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
219 Correct libc_version path detection, since it was screwing up if libdir !=
220 "/lib/".
221
222 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
223 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
224
225 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
226 Fix symbols.in not added to dist.
227
228 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
229 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
230 White space fixes.
231
232 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
233 configure.in, getcwd.c, libsandbox.c, symbols.in:
234 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
235 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
236 for glibc and other libc's that use this. Update libsandbox.c to use these
237 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
238 process unset it.
239
240 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
241 killed off _init and _fini in favor of
242 void __attribute__ ((constructor)) init_func and
243 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
244
245 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
246 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
247 having the hick-ups.
248
249 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
250 Makefile.am: Fixed compilation.
251
252 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
253 Gutted the bugger so it stops checking for a c++ and fortran compiler.
254 Do *not* regenerate aclocal.m4 for making a release until a better
255 solution is created.
256
257 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
258 Removal of more hardcoded paths.
259
260 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
261 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
262
263 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
264 Sandbox is now autotooled, create-localdecls needs to be killed and the code
265 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
266 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
267 To get to a point of testing, automake && autoconf; created requisite files w/
268 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
269 /lib and /usr/lib/portage/bin.
270
271 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
272 closing out bug #70225, potential overflow of the sandbox_pids_file var.
273
274 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
275 (think it was at least) allows intermixing of code and data segments. bug #70351
276 should be fixed by this.
277
278 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
279 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
280
281 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
282 Seth Robertson that tracked down all adjuct flags for read operations that
283 do not invoke a write operation.
284
285 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
286 Another fix from jstubbs regarding a free() on a stack variable for the
287 environment -- tracking now prevents extraneous free()'s segfault.
288
289 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
290 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
291 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
292 Also remove the errno = ESUCCESS settings as documentation points out that
293 a library isn't allowed to do that.
294
295 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
296 file_security_check() function to check random potential exploits on files
297 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
298 the 'system-crippling' exploits (bug 21923) and catches a few other
299 potential problems.
300
301 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
302 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
303
304 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
305 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
306 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
307
308 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
309 Fix permissions and group of pids file and logs. Permissions should be 0664
310 and group should be 'portage'. Bug #34260.
311
312 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
313 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
314 to the real execve (in our execve wrapper). Seems that on some arches (sparc
315 among others) do not allow us to tamper with the readonly copy passed to
316 execve, so pass our own copy of the environment. Bug #42290.
317
318 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
319 Changed tail to head and added a notice about duration of glibc check.
320
321 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
322 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
323 as there isn't a guarentee that it is dynamic.
324
325 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
326 If 'file' passed to before_syscall(const char *func, const char *file) is
327 invalid, we should set errno to ENOENT, and not EINVAL. This should
328 close bug #32238.
329
330 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
331 Fix a bug that occurs mainly on 64bit arch, where the file passed to
332 the functions we wrap, is invalid, and then cause canonicalize to pass
333 garbage to before_syscall(), thanks to great detective work from
334 Andrea Luzzardi <al@sig11.org> (bug #29846).
335
336 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
337 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
338
339 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
340 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
341 only checked the destination patch, and not the source, so we could move
342 a protected file to a unprotected directory, and then delete/modify it.
343 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
344
345 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
346 Added python2.3 to the predict section/variable.
347
348 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
349 sandbox.h, sandbox_futils.c :
350 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
351 it is not set, it will revert to its old value.
352
353 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
354 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
355 rather than failing with a violation, bug #29748.
356
357 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
358 Fix canonicalize() to ignore calls with path = "".
359
360 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
361 sandbox_futils.c, canonicalize.c :
362 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
363 call handled strings larger than PATH_MAX (bug #21766). It however does not
364 work the same on 2.4 kernels.
365
366 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
367 do not need the system call. We use the default getcwd() function via a
368 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
369 means the current directory was removed, OR that the the system call for
370 getcwd failed (curious is that it do not fail and return NULL or set
371 errno, but rather just truncate the retured directory - usually from the
372 start), and if so, we use the generic getcwd() function (__egetcwd). Note
373 that we do not use the generic version all the time, as it calls lstat()
374 a great number of times, and performance degrade much.
375
376 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
377 libsandbox.c :
378 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
379
380 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
381 create-localdecls :
382 When checking path names of files accessed, we need to canonicalize it, else
383 it may be a symlink in a 'write allowed' directory pointing to a file in a
384 directory we should not have write access to.
385
386 With something like coreutils-5.0, we have two problems:
387 1) One of the tests checks if getcwd() can return a path longer than
388 PATH_MAX. This test then tries to create a dir which even while
389 created local (mkdir("conftest2")), it ends up being resolved with
390 a name that is much larger than PATH_MAX. The problem now is that
391 canonicalize() have undefined behaviour when the path was too long
392 (returned wrongly truncated paths, etc), and pass the wrong path to
393 before_syscall() (causing the bogus sandbox violations).
394 2) The ecanonicalize() function we used, along with the canonicalize()
395 function did not support longer than PATH_MAX. This is partly a
396 cause for 1), but the error checking (rather lack of it) of calls
397 to erealpath() in canonicalize() was the prime reason for 1).
398
399 As we do not use this canonicalized name to call the function, we resolve this
400 by fixing canonicalize() to do better error checking, and ecanonicalize() as
401 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
402 While they will resolve paths properly now, and can check if a write/read is
403 allowed, the functions called from the sandboxed environment will still work
404 as expected.
405
406 This should resolve bug #21766.
407
408 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
409 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
410 it (bug #16298).
411
412 Problem is that for some reason locale fopen's locale.alias with mode "rm".
413
414 -------------------------------------------------------
415 nosferatu root # grep fopen locale.log
416 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
417 nosferatu root #
418 --------------------------------------------------------
419
420 I checked the source of locale, but it have fopen with mode 'r', so
421 not sure where the "rm" mode comes from. Anyhow, changed the check in
422 before_syscall_open_char() to also see mode "rm" as readonly.
423
424 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
425
426 Add glibc-2.3 support.
427
428 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
429
430 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
431 operations releated to preload, as well as only try to modify ld.so.preload
432 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
433 not using ld.so.preload. Fix to not write this instance of sandbox's pid
434 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
435
436 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
437
438 Changed the LD to CC for hppa.
439
440 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
441
442 Killed the previous changes I made.
443
444 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
445
446 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
447
448 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
449
450 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
451
452 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
453
454 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
455 for this fix.
456
457 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
458
459 sandbox_futils defined a dirname() function that was masking the same
460 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
461 '/usr/lib/portage/bi/'). Fixed function to return expected results and
462 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
463 11231.
464
465 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
466
467 Fix a segfault in libsandbox.c if canonicalize() was called with
468 first parameter = NULL.
469
470 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
471
472 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
473 cleanup() for this.
474
475 Change cleanup() in sandbox.c not to exit with fail status if
476 the pidsfile is missing. We really should still display sandbox
477 violations if they occured.
478
479 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
480
481 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
482 the last sandbox running.
483
484 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
485
486 Major cleanups to mainly libsandbox.c again.
487
488 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
489
490 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
491 parties involved should please contact me so that we can fix it.
492
493 Add opendir wrapper to libsandbox.c.
494
495 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
496
497 Do some more cleanups to ecanonicalize(), as it dropped filenames in
498 rare cases (after my symlink cleanups), and caused glibc to bork.
499 These fixes went into canonicalize.c.
500
501 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
502
503 Fix spawn_shell() and main() in sandbox.c to properly return fail
504 status.
505
506 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
507
508 The new canonicalize() function in libsandbox.c also resolved symlinks,
509 which caused on cleaning sandbox errors if the symlink pointed to a
510 file in the live root. Ripped out canonicalize() and realpath() from
511 glibc; removed the symlink stuff, and changed them to ecanonicalize()
512 and erealpath().
513
514 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
515
516 Ripped out all the wrappers, and implemented those of InstallWatch.
517 Losts of cleanups and bugfixes. Implement a execve that forces
518 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
519 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
520 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
521 parts; it now have an install target.
522
523 Reformat the whole thing to look somewhat like the reworked sandbox.c
524 and new sandbox.h and sandbox_futils.c from:
525
526 Brad House <brad@mainstreetsoftworks.com>.
527
528 Additional Copyrights now due to the InstallWatch code:
