5 05 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6
7 Do not give an access violation if the access() system call do not have
8 write/read access - it does not actually modify, so we only need to return
9 not being able to write/read. Noted by Andres Loeh <kosmikus@gentoo.org>,
10 bug #101433.
11
12 If we are called from the command line, do not care about PORTAGE_TMPDIR,
13 and make the current directory the work directory. Also rename the variable
14 portage_tmp_dir to work_dir.
15
16 01 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
17
18 Still do normal log if debugging is requested.
19
20 Add support for SANDBOX_VERBOSE (enabled by default). Adjust SANDBOX_DEBUG
21 to only enable if equal to "1" or "yes".
22
23 Add /dev/tts to write permit, bug #42809.
24
25 27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
26 sandbox_futils.c:
27
28 Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that
29 in libsandbox .. bug #100309.
30
31 22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h:
32
33 Print all logging to stderr, bug #90343, comment #15, by Zac Medico.
34
35* sandbox-1.2.11 (2005/07/14)
36
37 14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
38 Fix getcwd, bug #98419.
39
40 08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c,
41 libsandbox.c:
42 - Try to cleanup and make error handling/printing consistent.
43 - Remove old logs if present and conflicting with current.
44 - Fix compile error with previous change, and return rather then exit().
45
46 07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
47 sandbox.h, sandbox_futils.c:
48 - Fix possible segfault in env init code.
49 - Major cleanup of sandbox_futils.c. Removed most of the functions as we now
50 write to /var/log/sandbox/, so in theory do not need all that.
51 - Redo the interface of the get_* functions so that we do not leak memory.
52 - Remove sandbox_dir and co - we are not using it anymore.
53 - Remove unused includes and variables.
54 - Only declare functions in sandbox_futils.c that are used in libsandbox.c when
55 OUTSIDE_LIBSANDBOX is not defined.
56 - Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log
57 printing's last line not honouring NOCOLOR.
58
59 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
60 libsandbox.c:
61 - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
62 write to it.
63 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
64 - Add check_prefixes() with major cleanup on check_access().
65 - Cleanup init_env_entries() and check_prefixes().
66
67 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
68 sandbox_futils.c, libsandbox.c:
69 Remove unused 'pids file' code.
70
71* sandbox-1.2.10 (2005/07/03)
72
73 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
74 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
75
76 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
77 General cleanups:
78 - Remove fooling around with exit codes - we error out on presence of a log
79 anyhow.
80 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
81 appropriate there.
82
83 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
84 Cleanup the fail_nametoolong stuff a bit more.
85
86 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
87 Remove hopefully the last ld.so.preload bits we do not use anymore.
88
89 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
90 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
91 in check_syscall(). Should speed things up a bit (at least for the getcwd()
92 and long path name test it goes down to under a second, and not 10+ seconds
93 like before). Also warn if we skip checking due to the canonicalized path
94 being too long.
95
96 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
97 More comment/readability cleanups.
98
99 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
100 sandbox_futils.c, libsandbox.c:
101 Some strncpy/strncat and other cleanups.
102
103* sandbox-1.2.9 (2005/06/09)
104
105 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
106 Move symlink hack down a bit to try and minimize on the amount of lstat()
107 calls we do.
108
109 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
110 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
111
112 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
113 Add wrapper for access() function, bug #85413.
114
115 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
116 Use generic getcwd() implementation from uclibc - should be more portable
117 and looks a bit cleaner.
118
119 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
120 Make sure our true_* pointers are initialized to NULL, and that we check for
121 all references that they are valid.
122
123 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
124 Be default we will fail if the path name we try to canonicalize is too long.
125 This however could cause issues with some things (bug #94630 and #21766), so
126 if fail_nametoolong == 0, canonicalize() will return a null length string and
127 do not fail.
128
129 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
130 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
131 make sure we re-export the new TMPDIR environment variable.
132
133 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
134 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
135 by Marcus D. Hanwell <cryos@gentoo.org>.
136
137 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
138 Add /dev/console to write list, bug #38588.
139
140* sandbox-1.2.8 (2005/05/13)
141
142 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
143 sandbox.h, sandbox_futils.c:
144 General cleanups.
145
146 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
147 sandbox.h:
148 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
149
150 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
151 sandbox.h, sandbox_futils.c:
152 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
153 to use TMPDIR if present in environment.
154
155 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
156 Remove sandbox_log_file from main() as its no longer used.
157
158 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
159 sandbox_futils.c:
160 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
161 if already exported when sandbox started). Fix get_sandbox_log() and new
162 get_sandbox_debug_log() to not use already exported environment variables if
163 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
164 SB_PATH_MAX fixes.
165
166* sandbox-1.2.7 (2005/05/12)
167
168 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
169 sandbox_futils.c:
170 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
171
172 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
173 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
174 with '(null)' in it if we did not call sandbox with absolute path.
175
176 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
177 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
178 for the child.
179
180 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
181 Remove global preload_adaptable as it is no longer used.
182
183 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
184 Rewrite environment stuff to only be set when execve'ing the child process
185 to try and avoid issues like bug #91541 that causes sandbox to crash if
186 we set LD_PRELOAD sandbox side already.
187
188 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
189 Move print_sandbox_log() up to make things neater.
190
191 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
192 Remove load_preload_libs(), as its not used anymore.
193
194 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
195 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
196
197 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
198 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
199
200 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
201 Remove ld.so.preload crap - we are not going to use it again.
202
203 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
204 Fix typo in code that checks if we got valid group information, causing a
205 segmentation fault, bug #91637.
206
207* sandbox-1.2.6 (2005/05/10)
208
209 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
210 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
211 for some odd reason, bug #91541.
212
213 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
214 Fix typo (sizeof -> strlen).
215
216 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
217 rewrote the sbcontext caching code so it accounts for env changes since lib
218 initialization.
219
220 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
221 We create libctest.c via configure, so no need to keep it around. Do some
222 cleanup related to libctest.c and libctest during configure.
223
224 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
225 Add rename support of symlinks pointing to protected files/directories.
226
227* sandbox-1.2.5 (2005/05/04)
228
229 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
230 sandbox.bashrc:
231 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
232 already set, init of the env vars fails for some reason, so do this later on,
233 and do not warn (bug #91431).
234
235 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
236 sandbox.bashrc:
237 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
238
239* sandbox-1.2.4 (2005/05/03)
240
241 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
242 Do not init the env entries with each call, as it creates too many calls to
243 lstat, etc. Should speedup things a bit, bug #91040.
244
245 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
246 Add /dev/pty to default write list. Noticed by Morfic.
247
248 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
249 sandbox.h:
250 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
251 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
252
253* sandbox-1.2.3 (2005/04/29)
254
255 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
256 Do not check for (*&#$(* CXX or F77.
257
258 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
259 Do not append '/' to pathname in filter_path() if it already ends with it.
260
261 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
262 With az's help, clean up autotools to work with cross-compiling.
263
264* sandbox-1.2.2 (2005/04/28)
4 265
5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 266 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 267 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 268 have issues; bug #90592.

9* sandbox-1.2.1 270* sandbox-1.2.1 (2005/04/23)
10 271
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 272 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 273 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 274 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 275 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 276 linking with its object. Hopefully this will fix bug #90153.
16 277
