5* sandbox-1.2.14 (2005/11/28)
6
7 28 Nov 2005 Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
8 sandbox.c, sandbox.h, sandbox.bashrc:
9
10 Check generic getcwd()'s return as well for validity, bug #101728.
11
12 Cleanup environ variables.
13
14 Rather check SANDBOX_ACTIVE if we are already running. Set SANDBOX_ACTIVE
15 to readonly in sandbox.bashrc.
16
17 Make sure we use our bashrc.
18
19 01 Nov 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
20
21 Do not pass mode to true_open and true_open64 if not needed. Should fix a
22 segfault in some cases.
23
24* sandbox-1.2.13 (2005/09/12)
25
26 12 Sep 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, libsandbox.c:
27
28 Do not handle adding working directory to SANDBOX_WRITE, as portage does it
29 itself.
30
31 Make libsb_fini() do cleanup a bit more complete just in case we get another
32 uClibc 'call preloaded library fini before that of app' issue ... probably
33 will not help much, but we try.
34
35 04 Sep 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
36
37 Also allow symlink() system call to operate on a symlink in a writable path
38 that points to non-writable path, bug #104711.
39
40* sandbox-1.2.12 (2005/08/05)
41
42 05 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
43 sandbox.h:
44
45 Do not give an access violation if the access() system call do not have
46 write/read access - it does not actually modify, so we only need to return
47 not being able to write/read. Noted by Andres Loeh <kosmikus@gentoo.org>,
48 bug #101433.
49
50 If we are called from the command line, do not care about PORTAGE_TMPDIR,
51 and make the current directory the work directory. Also rename the variable
52 portage_tmp_dir to work_dir.
53
54 Remove the tmp_dir variable - we do not need it.
55
56 Improve error handling for get_sandbox_*_envvar() functions.
57
58 01 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
59
60 Still do normal log if debugging is requested.
61
62 Add support for SANDBOX_VERBOSE (enabled by default). Adjust SANDBOX_DEBUG
63 to only enable if equal to "1" or "yes".
64
65 Add /dev/tts to write permit, bug #42809.
66
67 27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
68 sandbox_futils.c:
69
70 Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that
71 in libsandbox .. bug #100309.
72
73 22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h:
74
75 Print all logging to stderr, bug #90343, comment #15, by Zac Medico.
76
77* sandbox-1.2.11 (2005/07/14)
78
79 14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
80 Fix getcwd, bug #98419.
81
82 08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c,
83 libsandbox.c:
84 - Try to cleanup and make error handling/printing consistent.
85 - Remove old logs if present and conflicting with current.
86 - Fix compile error with previous change, and return rather then exit().
87
88 07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
89 sandbox.h, sandbox_futils.c:
90 - Fix possible segfault in env init code.
91 - Major cleanup of sandbox_futils.c. Removed most of the functions as we now
92 write to /var/log/sandbox/, so in theory do not need all that.
93 - Redo the interface of the get_* functions so that we do not leak memory.
94 - Remove sandbox_dir and co - we are not using it anymore.
95 - Remove unused includes and variables.
96 - Only declare functions in sandbox_futils.c that are used in libsandbox.c when
97 OUTSIDE_LIBSANDBOX is not defined.
98 - Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log
99 printing's last line not honouring NOCOLOR.
100
101 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
102 libsandbox.c:
103 - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
104 write to it.
105 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
106 - Add check_prefixes() with major cleanup on check_access().
107 - Cleanup init_env_entries() and check_prefixes().
108
109 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
110 sandbox_futils.c, libsandbox.c:
111 Remove unused 'pids file' code.
112
113* sandbox-1.2.10 (2005/07/03)
114
115 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
116 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
117
118 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
119 General cleanups:
120 - Remove fooling around with exit codes - we error out on presence of a log
121 anyhow.
122 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
123 appropriate there.
124
125 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
126 Cleanup the fail_nametoolong stuff a bit more.
127
128 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
129 Remove hopefully the last ld.so.preload bits we do not use anymore.
130
131 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
132 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
133 in check_syscall(). Should speed things up a bit (at least for the getcwd()
134 and long path name test it goes down to under a second, and not 10+ seconds
135 like before). Also warn if we skip checking due to the canonicalized path
136 being too long.
137
138 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
139 More comment/readability cleanups.
140
141 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
142 sandbox_futils.c, libsandbox.c:
143 Some strncpy/strncat and other cleanups.
144
145* sandbox-1.2.9 (2005/06/09)
146
147 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
148 Move symlink hack down a bit to try and minimize on the amount of lstat()
149 calls we do.
150
151 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
152 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
153
154 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
155 Add wrapper for access() function, bug #85413.
156
157 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
158 Use generic getcwd() implementation from uclibc - should be more portable
159 and looks a bit cleaner.
160
161 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
162 Make sure our true_* pointers are initialized to NULL, and that we check for
163 all references that they are valid.
164
165 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
166 Be default we will fail if the path name we try to canonicalize is too long.
167 This however could cause issues with some things (bug #94630 and #21766), so
168 if fail_nametoolong == 0, canonicalize() will return a null length string and
169 do not fail.
170
171 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
172 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
173 make sure we re-export the new TMPDIR environment variable.
174
175 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
176 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
177 by Marcus D. Hanwell <cryos@gentoo.org>.
178
179 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
180 Add /dev/console to write list, bug #38588.
181
182* sandbox-1.2.8 (2005/05/13)
183
184 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
185 sandbox.h, sandbox_futils.c:
186 General cleanups.
187
188 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
189 sandbox.h:
190 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
191
192 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
193 sandbox.h, sandbox_futils.c:
194 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
195 to use TMPDIR if present in environment.
196
197 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
198 Remove sandbox_log_file from main() as its no longer used.
199
200 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
201 sandbox_futils.c:
202 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
203 if already exported when sandbox started). Fix get_sandbox_log() and new
204 get_sandbox_debug_log() to not use already exported environment variables if
205 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
206 SB_PATH_MAX fixes.
207
208* sandbox-1.2.7 (2005/05/12)
209
210 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
211 sandbox_futils.c:
212 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
213
214 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
215 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
216 with '(null)' in it if we did not call sandbox with absolute path.
217
218 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
219 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
220 for the child.
221
222 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
223 Remove global preload_adaptable as it is no longer used.
224
225 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
226 Rewrite environment stuff to only be set when execve'ing the child process
227 to try and avoid issues like bug #91541 that causes sandbox to crash if
228 we set LD_PRELOAD sandbox side already.
229
230 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
231 Move print_sandbox_log() up to make things neater.
232
233 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
234 Remove load_preload_libs(), as its not used anymore.
235
236 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
237 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
238
239 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
240 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
241
242 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
243 Remove ld.so.preload crap - we are not going to use it again.
244
245 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
246 Fix typo in code that checks if we got valid group information, causing a
247 segmentation fault, bug #91637.
248
249* sandbox-1.2.6 (2005/05/10)
250
251 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
252 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
253 for some odd reason, bug #91541.
254
255 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
256 Fix typo (sizeof -> strlen).
257
258 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
259 rewrote the sbcontext caching code so it accounts for env changes since lib
260 initialization.
261
262 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
263 We create libctest.c via configure, so no need to keep it around. Do some
264 cleanup related to libctest.c and libctest during configure.
265
266 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
267 Add rename support of symlinks pointing to protected files/directories.
268
269* sandbox-1.2.5 (2005/05/04)
270
271 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
272 sandbox.bashrc:
273 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
274 already set, init of the env vars fails for some reason, so do this later on,
275 and do not warn (bug #91431).
276
277 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
278 sandbox.bashrc:
279 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
280
281* sandbox-1.2.4 (2005/05/03)
282
283 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
284 Do not init the env entries with each call, as it creates too many calls to
285 lstat, etc. Should speedup things a bit, bug #91040.
286
287 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
288 Add /dev/pty to default write list. Noticed by Morfic.
289
290 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
291 sandbox.h:
292 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
293 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
294
295* sandbox-1.2.3 (2005/04/29)
296
297 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
298 Do not check for (*&#$(* CXX or F77.
299
300 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
301 Do not append '/' to pathname in filter_path() if it already ends with it.
302
303 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
304 With az's help, clean up autotools to work with cross-compiling.
305
306* sandbox-1.2.2 (2005/04/28)
4 307
5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 308 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm 309 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 310 have issues; bug #90592.
8 311
9* sandbox-1.2.1 312* sandbox-1.2.1 (2005/04/23)
10 313
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 314 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 315 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 316 Make sure all functions used in libsandbox.c is declared static. Define
14 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than 317 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 318 linking with its object. Hopefully this will fix bug #90153.
16 319
17* sandbox-1.2 320* sandbox-1.2 (2005/04/23)
18 321
19 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 322 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
20 Allow lchown a symlink in write-allowed path pointing to write-denied 323 Allow lchown a symlink in write-allowed path pointing to write-denied
21 target. 324 target.
