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