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