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

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 261 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 262 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 263 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 264 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 265 linking with its object. Hopefully this will fix bug #90153.
