5 27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
6 sandbox_futils.c:
7
8 Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that
9 in libsandbox .. bug #100309.
10
11 22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h:
12
13 Print all logging to stderr, bug #90343, comment #15, by Zac Medico.
14
15* sandbox-1.2.11 (2005/07/14)
16
17 14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
18 Fix getcwd, bug #98419.
19
20 08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c,
21 libsandbox.c:
22 - Try to cleanup and make error handling/printing consistent.
23 - Remove old logs if present and conflicting with current.
24 - Fix compile error with previous change, and return rather then exit().
25
26 07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
27 sandbox.h, sandbox_futils.c:
28 - Fix possible segfault in env init code.
29 - Major cleanup of sandbox_futils.c. Removed most of the functions as we now
30 write to /var/log/sandbox/, so in theory do not need all that.
31 - Redo the interface of the get_* functions so that we do not leak memory.
32 - Remove sandbox_dir and co - we are not using it anymore.
33 - Remove unused includes and variables.
34 - Only declare functions in sandbox_futils.c that are used in libsandbox.c when
35 OUTSIDE_LIBSANDBOX is not defined.
36 - Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log
37 printing's last line not honouring NOCOLOR.
38
39 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
40 libsandbox.c:
41 - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
42 write to it.
43 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
44 - Add check_prefixes() with major cleanup on check_access().
45 - Cleanup init_env_entries() and check_prefixes().
46
47 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
48 sandbox_futils.c, libsandbox.c:
49 Remove unused 'pids file' code.
50
51* sandbox-1.2.10 (2005/07/03)
52
53 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
54 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
55
56 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
57 General cleanups:
58 - Remove fooling around with exit codes - we error out on presence of a log
59 anyhow.
60 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
61 appropriate there.
62
63 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
64 Cleanup the fail_nametoolong stuff a bit more.
65
66 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
67 Remove hopefully the last ld.so.preload bits we do not use anymore.
68
69 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
70 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
71 in check_syscall(). Should speed things up a bit (at least for the getcwd()
72 and long path name test it goes down to under a second, and not 10+ seconds
73 like before). Also warn if we skip checking due to the canonicalized path
74 being too long.
75
76 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
77 More comment/readability cleanups.
78
79 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
80 sandbox_futils.c, libsandbox.c:
81 Some strncpy/strncat and other cleanups.
82
83* sandbox-1.2.9 (2005/06/09)
84
85 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
86 Move symlink hack down a bit to try and minimize on the amount of lstat()
87 calls we do.
88
89 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
90 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
91
92 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
93 Add wrapper for access() function, bug #85413.
94
95 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
96 Use generic getcwd() implementation from uclibc - should be more portable
97 and looks a bit cleaner.
98
99 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
100 Make sure our true_* pointers are initialized to NULL, and that we check for
101 all references that they are valid.
102
103 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
104 Be default we will fail if the path name we try to canonicalize is too long.
105 This however could cause issues with some things (bug #94630 and #21766), so
106 if fail_nametoolong == 0, canonicalize() will return a null length string and
107 do not fail.
108
109 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
110 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
111 make sure we re-export the new TMPDIR environment variable.
112
113 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
114 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
115 by Marcus D. Hanwell <cryos@gentoo.org>.
116
117 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
118 Add /dev/console to write list, bug #38588.
119
120* sandbox-1.2.8 (2005/05/13)
121
122 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
123 sandbox.h, sandbox_futils.c:
124 General cleanups.
125
126 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
127 sandbox.h:
128 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
129
130 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
131 sandbox.h, sandbox_futils.c:
132 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
133 to use TMPDIR if present in environment.
134
135 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
136 Remove sandbox_log_file from main() as its no longer used.
137
138 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
139 sandbox_futils.c:
140 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
141 if already exported when sandbox started). Fix get_sandbox_log() and new
142 get_sandbox_debug_log() to not use already exported environment variables if
143 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
144 SB_PATH_MAX fixes.
145
146* sandbox-1.2.7 (2005/05/12)
147
148 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
149 sandbox_futils.c:
150 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
151
152 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
153 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
154 with '(null)' in it if we did not call sandbox with absolute path.
155
156 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
157 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
158 for the child.
159
160 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
161 Remove global preload_adaptable as it is no longer used.
162
163 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
164 Rewrite environment stuff to only be set when execve'ing the child process
165 to try and avoid issues like bug #91541 that causes sandbox to crash if
166 we set LD_PRELOAD sandbox side already.
167
168 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
169 Move print_sandbox_log() up to make things neater.
170
171 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
172 Remove load_preload_libs(), as its not used anymore.
173
174 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
175 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
176
177 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
178 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
179
180 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
181 Remove ld.so.preload crap - we are not going to use it again.
182
183 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
184 Fix typo in code that checks if we got valid group information, causing a
185 segmentation fault, bug #91637.
186
187* sandbox-1.2.6 (2005/05/10)
188
189 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
190 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
191 for some odd reason, bug #91541.
192
193 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
194 Fix typo (sizeof -> strlen).
195
196 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
197 rewrote the sbcontext caching code so it accounts for env changes since lib
198 initialization.
199
200 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
201 We create libctest.c via configure, so no need to keep it around. Do some
202 cleanup related to libctest.c and libctest during configure.
203
204 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
205 Add rename support of symlinks pointing to protected files/directories.
206
207* sandbox-1.2.5 (2005/05/04)
208
209 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
210 sandbox.bashrc:
211 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
212 already set, init of the env vars fails for some reason, so do this later on,
213 and do not warn (bug #91431).
214
215 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
216 sandbox.bashrc:
217 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
218
219* sandbox-1.2.4 (2005/05/03)
220
221 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
222 Do not init the env entries with each call, as it creates too many calls to
223 lstat, etc. Should speedup things a bit, bug #91040.
224
225 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
226 Add /dev/pty to default write list. Noticed by Morfic.
227
228 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
229 sandbox.h:
230 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
231 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
232
233* sandbox-1.2.3 (2005/04/29)
234
235 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
236 Do not check for (*&#$(* CXX or F77.
237
238 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
239 Do not append '/' to pathname in filter_path() if it already ends with it.
240
241 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
242 With az's help, clean up autotools to work with cross-compiling.
243
244* sandbox-1.2.2 (2005/04/28)
4 245
5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 246 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 247 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 248 have issues; bug #90592.

9* sandbox-1.2.1 250* sandbox-1.2.1 (2005/04/23)
10 251
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 252 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 253 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 254 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 255 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 256 linking with its object. Hopefully this will fix bug #90153.
