5 01 Dec 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, Makefile.am,
6 localdecls.h, scripts/Makefile.am, scripts/gen_symbol_version_map.awk,
7 scripts/gen_symbol_header.awk, src/Makefile.am, src/symbols.in,
8 src/libsandbox.c, src/getcwd.c:
9
10 Use versioned symbols on supported libc's for functions we wrap, as well as
11 provide all versions of specific functions. Some syntax cleanups.
12
13 28 Nov 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, sandbox.c,
14 sandbox_fdutils.c:
15
16 Detect if we on 64bit arch automatically.
17
18 Update contact email. Fix quoting.
19
20 Revert 64bit arch test, as we should build the 32bit version without full
21 path checking as well, and add --enable-multilib switch to configure.
22
23* sandbox-1.2.14 (2005/11/28)
24
25 28 Nov 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
26 sandbox.c, sandbox.h, sandbox.bashrc:
27
28 Check generic getcwd()'s return as well for validity, bug #101728.
29
30 Cleanup environ variables.
31
32 Rather check SANDBOX_ACTIVE if we are already running. Set SANDBOX_ACTIVE
33 to readonly in sandbox.bashrc.
34
35 Make sure we use our bashrc.
36
37 01 Nov 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
38
39 Do not pass mode to true_open and true_open64 if not needed. Should fix a
40 segfault in some cases.
41
42* sandbox-1.2.13 (2005/09/12)
43
44 12 Sep 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, libsandbox.c:
45
46 Do not handle adding working directory to SANDBOX_WRITE, as portage does it
47 itself.
48
49 Make libsb_fini() do cleanup a bit more complete just in case we get another
50 uClibc 'call preloaded library fini before that of app' issue ... probably
51 will not help much, but we try.
52
53 04 Sep 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
54
55 Also allow symlink() system call to operate on a symlink in a writable path
56 that points to non-writable path, bug #104711.
57
58* sandbox-1.2.12 (2005/08/05)
59
60 05 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
61 sandbox.h:
62
63 Do not give an access violation if the access() system call do not have
64 write/read access - it does not actually modify, so we only need to return
65 not being able to write/read. Noted by Andres Loeh <kosmikus@gentoo.org>,
66 bug #101433.
67
68 If we are called from the command line, do not care about PORTAGE_TMPDIR,
69 and make the current directory the work directory. Also rename the variable
70 portage_tmp_dir to work_dir.
71
72 Remove the tmp_dir variable - we do not need it.
73
74 Improve error handling for get_sandbox_*_envvar() functions.
75
76 01 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
77
78 Still do normal log if debugging is requested.
79
80 Add support for SANDBOX_VERBOSE (enabled by default). Adjust SANDBOX_DEBUG
81 to only enable if equal to "1" or "yes".
82
83 Add /dev/tts to write permit, bug #42809.
84
85 27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
86 sandbox_futils.c:
87
88 Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that
89 in libsandbox .. bug #100309.
90
91 22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h:
92
93 Print all logging to stderr, bug #90343, comment #15, by Zac Medico.
94
95* sandbox-1.2.11 (2005/07/14)
96
97 14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
98 Fix getcwd, bug #98419.
99
100 08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c,
101 libsandbox.c:
102 - Try to cleanup and make error handling/printing consistent.
103 - Remove old logs if present and conflicting with current.
104 - Fix compile error with previous change, and return rather then exit().
105
106 07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
107 sandbox.h, sandbox_futils.c:
108 - Fix possible segfault in env init code.
109 - Major cleanup of sandbox_futils.c. Removed most of the functions as we now
110 write to /var/log/sandbox/, so in theory do not need all that.
111 - Redo the interface of the get_* functions so that we do not leak memory.
112 - Remove sandbox_dir and co - we are not using it anymore.
113 - Remove unused includes and variables.
114 - Only declare functions in sandbox_futils.c that are used in libsandbox.c when
115 OUTSIDE_LIBSANDBOX is not defined.
116 - Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log
117 printing's last line not honouring NOCOLOR.
118
119 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
120 libsandbox.c:
121 - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
122 write to it.
123 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
124 - Add check_prefixes() with major cleanup on check_access().
125 - Cleanup init_env_entries() and check_prefixes().
126
127 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
128 sandbox_futils.c, libsandbox.c:
129 Remove unused 'pids file' code.
130
131* sandbox-1.2.10 (2005/07/03)
132
133 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
134 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
135
136 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
137 General cleanups:
138 - Remove fooling around with exit codes - we error out on presence of a log
139 anyhow.
140 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
141 appropriate there.
142
143 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
144 Cleanup the fail_nametoolong stuff a bit more.
145
146 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
147 Remove hopefully the last ld.so.preload bits we do not use anymore.
148
149 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
150 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
151 in check_syscall(). Should speed things up a bit (at least for the getcwd()
152 and long path name test it goes down to under a second, and not 10+ seconds
153 like before). Also warn if we skip checking due to the canonicalized path
154 being too long.
155
156 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
157 More comment/readability cleanups.
158
159 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
160 sandbox_futils.c, libsandbox.c:
161 Some strncpy/strncat and other cleanups.
162
163* sandbox-1.2.9 (2005/06/09)
164
165 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
166 Move symlink hack down a bit to try and minimize on the amount of lstat()
167 calls we do.
168
169 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
170 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
171
172 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
173 Add wrapper for access() function, bug #85413.
174
175 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
176 Use generic getcwd() implementation from uclibc - should be more portable
177 and looks a bit cleaner.
178
179 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
180 Make sure our true_* pointers are initialized to NULL, and that we check for
181 all references that they are valid.
182
183 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
184 Be default we will fail if the path name we try to canonicalize is too long.
185 This however could cause issues with some things (bug #94630 and #21766), so
186 if fail_nametoolong == 0, canonicalize() will return a null length string and
187 do not fail.
188
189 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
190 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
191 make sure we re-export the new TMPDIR environment variable.
192
193 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
194 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
195 by Marcus D. Hanwell <cryos@gentoo.org>.
196
197 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
198 Add /dev/console to write list, bug #38588.
199
200* sandbox-1.2.8 (2005/05/13)
201
202 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
203 sandbox.h, sandbox_futils.c:
204 General cleanups.
205
206 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
207 sandbox.h:
208 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
209
210 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
211 sandbox.h, sandbox_futils.c:
212 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
213 to use TMPDIR if present in environment.
214
215 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
216 Remove sandbox_log_file from main() as its no longer used.
217
218 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
219 sandbox_futils.c:
220 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
221 if already exported when sandbox started). Fix get_sandbox_log() and new
222 get_sandbox_debug_log() to not use already exported environment variables if
223 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
224 SB_PATH_MAX fixes.
225
226* sandbox-1.2.7 (2005/05/12)
227
228 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
229 sandbox_futils.c:
230 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
231
232 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
233 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
234 with '(null)' in it if we did not call sandbox with absolute path.
235
236 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
237 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
238 for the child.
239
240 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
241 Remove global preload_adaptable as it is no longer used.
242
243 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
244 Rewrite environment stuff to only be set when execve'ing the child process
245 to try and avoid issues like bug #91541 that causes sandbox to crash if
246 we set LD_PRELOAD sandbox side already.
247
248 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
249 Move print_sandbox_log() up to make things neater.
250
251 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
252 Remove load_preload_libs(), as its not used anymore.
253
254 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
255 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
256
257 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
258 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
259
260 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
261 Remove ld.so.preload crap - we are not going to use it again.
262
263 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
264 Fix typo in code that checks if we got valid group information, causing a
265 segmentation fault, bug #91637.
266
267* sandbox-1.2.6 (2005/05/10)
268
269 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
270 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
271 for some odd reason, bug #91541.
272
273 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
274 Fix typo (sizeof -> strlen).
275
276 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
277 rewrote the sbcontext caching code so it accounts for env changes since lib
278 initialization.
279
280 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
281 We create libctest.c via configure, so no need to keep it around. Do some
282 cleanup related to libctest.c and libctest during configure.
283
284 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
285 Add rename support of symlinks pointing to protected files/directories.
286
287* sandbox-1.2.5 (2005/05/04)
288
289 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
290 sandbox.bashrc:
291 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
292 already set, init of the env vars fails for some reason, so do this later on,
293 and do not warn (bug #91431).
294
295 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
296 sandbox.bashrc:
297 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
298
299* sandbox-1.2.4 (2005/05/03)
300
301 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
302 Do not init the env entries with each call, as it creates too many calls to
303 lstat, etc. Should speedup things a bit, bug #91040.
304
305 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
306 Add /dev/pty to default write list. Noticed by Morfic.
307
308 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
309 sandbox.h:
310 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
311 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
312
313* sandbox-1.2.3 (2005/04/29)
314
315 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
316 Do not check for (*&#$(* CXX or F77.
317
318 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
319 Do not append '/' to pathname in filter_path() if it already ends with it.
320
321 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
322 With az's help, clean up autotools to work with cross-compiling.
323
324* sandbox-1.2.2 (2005/04/28)
325
326 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
327 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
328 have issues; bug #90592.
329
330* sandbox-1.2.1 (2005/04/23)
331
332 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
333 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
334 Make sure all functions used in libsandbox.c is declared static. Define
335 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
336 linking with its object. Hopefully this will fix bug #90153.
337
338* sandbox-1.2 (2005/04/23)
339
340 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
341 Allow lchown a symlink in write-allowed path pointing to write-denied
342 target.
343
344 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
345 Also show resolved symlink names in the log.
346
347 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
348 Seems -nostdlib was the problem with the constructor/destructor - remove it
349 from Makefile.am, and change the constructor/destructor names again.
350
351 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
352 Also rename the _init() and _fini() declarations.
353
354 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
355 Fixup the constructor/destructor function names again (they should be _init()
356 and _fini() it seems, and not being called caused sandbox_lib_path to be
357 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
358 Add both the path in given SANDBOX_x variable, as well as its symlink
359 resolved path in init_env_entries(). Modify filter_path() to be able to
360 resolve paths without resolving symlinks, as well as to be able to resolve
361 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
362 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
363 for bug #31019 cause access violations if we try to remove a symlink that is
364 not in protected path, but points to a protected path. Fix a memory leak in
365 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
366 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
367 (pid_string was uninitialized). General syntax cleanups.
368
369 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
370 infamous "pids file is not a regular file" w/out newline bug.
371
372 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
373 Correct libc_version path detection, since it was screwing up if libdir !=
374 "/lib/".
375
376 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
377 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
378
379 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
380 Fix symbols.in not added to dist.
381
382 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
383 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
384 White space fixes.
385
386 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
387 configure.in, getcwd.c, libsandbox.c, symbols.in:
388 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
389 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
390 for glibc and other libc's that use this. Update libsandbox.c to use these
391 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
392 process unset it.
393
5 01 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c: 394 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
6 killed off _init and _fini in favor of 395 killed off _init and _fini in favor of
7 void __attribute__ ((constructor)) init_func and 396 void __attribute__ ((constructor)) init_func and
8 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated. 397 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
