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

4 235
5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 236 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 237 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 238 have issues; bug #90592.

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 242 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 243 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 244 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 245 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 246 linking with its object. Hopefully this will fix bug #90153.
