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