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

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 226 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 227 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 228 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 229 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 230 linking with its object. Hopefully this will fix bug #90153.
