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

4 233
5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 234 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 235 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 236 have issues; bug #90592.

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 240 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 241 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 242 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 243 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 244 linking with its object. Hopefully this will fix bug #90153.
