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

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 231 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 232 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 233 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 234 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 235 linking with its object. Hopefully this will fix bug #90153.
