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

9* sandbox-1.2.1 233* sandbox-1.2.1 (2005/04/23)
10 234
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 235 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 236 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 237 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 238 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 239 linking with its object. Hopefully this will fix bug #90153.
