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

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 246 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 247 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 248 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 249 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 250 linking with its object. Hopefully this will fix bug #90153.
