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