5 01 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6
7 Still do normal log if debugging is requested.
8
9 27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
10 sandbox_futils.c:
11
12 Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that
13 in libsandbox .. bug #100309.
14
15 22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h:
16
17 Print all logging to stderr, bug #90343, comment #15, by Zac Medico.
18
19* sandbox-1.2.11 (2005/07/14)
20
21 14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
22 Fix getcwd, bug #98419.
23
24 08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c,
25 libsandbox.c:
26 - Try to cleanup and make error handling/printing consistent.
27 - Remove old logs if present and conflicting with current.
28 - Fix compile error with previous change, and return rather then exit().
29
30 07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
31 sandbox.h, sandbox_futils.c:
32 - Fix possible segfault in env init code.
33 - Major cleanup of sandbox_futils.c. Removed most of the functions as we now
34 write to /var/log/sandbox/, so in theory do not need all that.
35 - Redo the interface of the get_* functions so that we do not leak memory.
36 - Remove sandbox_dir and co - we are not using it anymore.
37 - Remove unused includes and variables.
38 - Only declare functions in sandbox_futils.c that are used in libsandbox.c when
39 OUTSIDE_LIBSANDBOX is not defined.
40 - Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log
41 printing's last line not honouring NOCOLOR.
42
43 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
44 libsandbox.c:
45 - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
46 write to it.
47 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
48 - Add check_prefixes() with major cleanup on check_access().
49 - Cleanup init_env_entries() and check_prefixes().
50
51 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
52 sandbox_futils.c, libsandbox.c:
53 Remove unused 'pids file' code.
54
55* sandbox-1.2.10 (2005/07/03)
56
57 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
58 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
59
60 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
61 General cleanups:
62 - Remove fooling around with exit codes - we error out on presence of a log
63 anyhow.
64 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
65 appropriate there.
66
67 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
68 Cleanup the fail_nametoolong stuff a bit more.
69
70 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
71 Remove hopefully the last ld.so.preload bits we do not use anymore.
72
73 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
74 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
75 in check_syscall(). Should speed things up a bit (at least for the getcwd()
76 and long path name test it goes down to under a second, and not 10+ seconds
77 like before). Also warn if we skip checking due to the canonicalized path
78 being too long.
79
80 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
81 More comment/readability cleanups.
82
83 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
84 sandbox_futils.c, libsandbox.c:
85 Some strncpy/strncat and other cleanups.
86
87* sandbox-1.2.9 (2005/06/09)
88
89 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
90 Move symlink hack down a bit to try and minimize on the amount of lstat()
91 calls we do.
92
93 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
94 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
95
96 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
97 Add wrapper for access() function, bug #85413.
98
99 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
100 Use generic getcwd() implementation from uclibc - should be more portable
101 and looks a bit cleaner.
102
103 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
104 Make sure our true_* pointers are initialized to NULL, and that we check for
105 all references that they are valid.
106
107 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
108 Be default we will fail if the path name we try to canonicalize is too long.
109 This however could cause issues with some things (bug #94630 and #21766), so
110 if fail_nametoolong == 0, canonicalize() will return a null length string and
111 do not fail.
112
113 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
114 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
115 make sure we re-export the new TMPDIR environment variable.
116
117 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
118 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
119 by Marcus D. Hanwell <cryos@gentoo.org>.
120
121 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
122 Add /dev/console to write list, bug #38588.
123
124* sandbox-1.2.8 (2005/05/13)
125
126 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
127 sandbox.h, sandbox_futils.c:
128 General cleanups.
129
130 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
131 sandbox.h:
132 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
133
134 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
135 sandbox.h, sandbox_futils.c:
136 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
137 to use TMPDIR if present in environment.
138
139 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
140 Remove sandbox_log_file from main() as its no longer used.
141
142 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
143 sandbox_futils.c:
144 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
145 if already exported when sandbox started). Fix get_sandbox_log() and new
146 get_sandbox_debug_log() to not use already exported environment variables if
147 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
148 SB_PATH_MAX fixes.
149
150* sandbox-1.2.7 (2005/05/12)
151
152 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
153 sandbox_futils.c:
154 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
155
156 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
157 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
158 with '(null)' in it if we did not call sandbox with absolute path.
159
160 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
161 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
162 for the child.
163
164 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
165 Remove global preload_adaptable as it is no longer used.
166
167 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
168 Rewrite environment stuff to only be set when execve'ing the child process
169 to try and avoid issues like bug #91541 that causes sandbox to crash if
170 we set LD_PRELOAD sandbox side already.
171
172 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
173 Move print_sandbox_log() up to make things neater.
174
175 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
176 Remove load_preload_libs(), as its not used anymore.
177
178 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
179 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
180
181 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
182 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
183
184 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
185 Remove ld.so.preload crap - we are not going to use it again.
186
187 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
188 Fix typo in code that checks if we got valid group information, causing a
189 segmentation fault, bug #91637.
190
191* sandbox-1.2.6 (2005/05/10)
192
193 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
194 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
195 for some odd reason, bug #91541.
196
197 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
198 Fix typo (sizeof -> strlen).
199
200 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
201 rewrote the sbcontext caching code so it accounts for env changes since lib
202 initialization.
203
204 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
205 We create libctest.c via configure, so no need to keep it around. Do some
206 cleanup related to libctest.c and libctest during configure.
207
208 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
209 Add rename support of symlinks pointing to protected files/directories.
210
211* sandbox-1.2.5 (2005/05/04)
212
213 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
214 sandbox.bashrc:
215 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
216 already set, init of the env vars fails for some reason, so do this later on,
217 and do not warn (bug #91431).
218
219 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
220 sandbox.bashrc:
221 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
222
223* sandbox-1.2.4 (2005/05/03)
224
225 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
226 Do not init the env entries with each call, as it creates too many calls to
227 lstat, etc. Should speedup things a bit, bug #91040.
228
229 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
230 Add /dev/pty to default write list. Noticed by Morfic.
231
232 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
233 sandbox.h:
234 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
235 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
236
237* sandbox-1.2.3 (2005/04/29)
238
239 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
240 Do not check for (*&#$(* CXX or F77.
241
242 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
243 Do not append '/' to pathname in filter_path() if it already ends with it.
244
245 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
246 With az's help, clean up autotools to work with cross-compiling.
247
248* sandbox-1.2.2 (2005/04/28)
4 249
5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 250 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 251 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 252 have issues; bug #90592.

9* sandbox-1.2.1 254* sandbox-1.2.1 (2005/04/23)
10 255
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 256 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 257 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 258 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 259 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 260 linking with its object. Hopefully this will fix bug #90153.
