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 Remove the tmp_dir variable - we do not need it.
17
18 01 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
19
20 Still do normal log if debugging is requested.
21
22 Add support for SANDBOX_VERBOSE (enabled by default). Adjust SANDBOX_DEBUG
23 to only enable if equal to "1" or "yes".
24
25 Add /dev/tts to write permit, bug #42809.
26
27 27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
28 sandbox_futils.c:
29
30 Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that
31 in libsandbox .. bug #100309.
32
33 22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h:
34
35 Print all logging to stderr, bug #90343, comment #15, by Zac Medico.
36
37* sandbox-1.2.11 (2005/07/14)
38
39 14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
40 Fix getcwd, bug #98419.
41
42 08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c,
43 libsandbox.c:
44 - Try to cleanup and make error handling/printing consistent.
45 - Remove old logs if present and conflicting with current.
46 - Fix compile error with previous change, and return rather then exit().
47
48 07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
49 sandbox.h, sandbox_futils.c:
50 - Fix possible segfault in env init code.
51 - Major cleanup of sandbox_futils.c. Removed most of the functions as we now
52 write to /var/log/sandbox/, so in theory do not need all that.
53 - Redo the interface of the get_* functions so that we do not leak memory.
54 - Remove sandbox_dir and co - we are not using it anymore.
55 - Remove unused includes and variables.
56 - Only declare functions in sandbox_futils.c that are used in libsandbox.c when
57 OUTSIDE_LIBSANDBOX is not defined.
58 - Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log
59 printing's last line not honouring NOCOLOR.
60
61 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
62 libsandbox.c:
63 - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
64 write to it.
65 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
66 - Add check_prefixes() with major cleanup on check_access().
67 - Cleanup init_env_entries() and check_prefixes().
68
69 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
70 sandbox_futils.c, libsandbox.c:
71 Remove unused 'pids file' code.
72
73* sandbox-1.2.10 (2005/07/03)
74
75 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
76 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
77
78 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
79 General cleanups:
80 - Remove fooling around with exit codes - we error out on presence of a log
81 anyhow.
82 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
83 appropriate there.
84
85 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
86 Cleanup the fail_nametoolong stuff a bit more.
87
88 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
89 Remove hopefully the last ld.so.preload bits we do not use anymore.
90
91 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
92 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
93 in check_syscall(). Should speed things up a bit (at least for the getcwd()
94 and long path name test it goes down to under a second, and not 10+ seconds
95 like before). Also warn if we skip checking due to the canonicalized path
96 being too long.
97
98 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
99 More comment/readability cleanups.
100
101 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
102 sandbox_futils.c, libsandbox.c:
103 Some strncpy/strncat and other cleanups.
104
105* sandbox-1.2.9 (2005/06/09)
106
107 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
108 Move symlink hack down a bit to try and minimize on the amount of lstat()
109 calls we do.
110
111 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
112 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
113
114 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
115 Add wrapper for access() function, bug #85413.
116
117 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
118 Use generic getcwd() implementation from uclibc - should be more portable
119 and looks a bit cleaner.
120
121 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
122 Make sure our true_* pointers are initialized to NULL, and that we check for
123 all references that they are valid.
124
125 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
126 Be default we will fail if the path name we try to canonicalize is too long.
127 This however could cause issues with some things (bug #94630 and #21766), so
128 if fail_nametoolong == 0, canonicalize() will return a null length string and
129 do not fail.
130
131 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
132 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
133 make sure we re-export the new TMPDIR environment variable.
134
135 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
136 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
137 by Marcus D. Hanwell <cryos@gentoo.org>.
138
139 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
140 Add /dev/console to write list, bug #38588.
141
142* sandbox-1.2.8 (2005/05/13)
143
144 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
145 sandbox.h, sandbox_futils.c:
146 General cleanups.
147
148 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
149 sandbox.h:
150 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
151
152 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
153 sandbox.h, sandbox_futils.c:
154 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
155 to use TMPDIR if present in environment.
156
157 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
158 Remove sandbox_log_file from main() as its no longer used.
159
160 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
161 sandbox_futils.c:
162 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
163 if already exported when sandbox started). Fix get_sandbox_log() and new
164 get_sandbox_debug_log() to not use already exported environment variables if
165 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
166 SB_PATH_MAX fixes.
167
168* sandbox-1.2.7 (2005/05/12)
169
170 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
171 sandbox_futils.c:
172 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
173
174 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
175 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
176 with '(null)' in it if we did not call sandbox with absolute path.
177
178 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
179 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
180 for the child.
181
182 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
183 Remove global preload_adaptable as it is no longer used.
184
185 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
186 Rewrite environment stuff to only be set when execve'ing the child process
187 to try and avoid issues like bug #91541 that causes sandbox to crash if
188 we set LD_PRELOAD sandbox side already.
189
190 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
191 Move print_sandbox_log() up to make things neater.
192
193 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
194 Remove load_preload_libs(), as its not used anymore.
195
196 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
197 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
198
199 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
200 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
201
202 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
203 Remove ld.so.preload crap - we are not going to use it again.
204
205 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
206 Fix typo in code that checks if we got valid group information, causing a
207 segmentation fault, bug #91637.
208
209* sandbox-1.2.6 (2005/05/10)
210
211 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
212 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
213 for some odd reason, bug #91541.
214
215 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
216 Fix typo (sizeof -> strlen).
217
218 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
219 rewrote the sbcontext caching code so it accounts for env changes since lib
220 initialization.
221
222 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
223 We create libctest.c via configure, so no need to keep it around. Do some
224 cleanup related to libctest.c and libctest during configure.
225
226 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
227 Add rename support of symlinks pointing to protected files/directories.
228
229* sandbox-1.2.5 (2005/05/04)
230
231 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
232 sandbox.bashrc:
233 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
234 already set, init of the env vars fails for some reason, so do this later on,
235 and do not warn (bug #91431).
236
237 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
238 sandbox.bashrc:
239 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
240
241* sandbox-1.2.4 (2005/05/03)
242
243 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
244 Do not init the env entries with each call, as it creates too many calls to
245 lstat, etc. Should speedup things a bit, bug #91040.
246
247 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
248 Add /dev/pty to default write list. Noticed by Morfic.
249
250 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
251 sandbox.h:
252 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
253 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
254
255* sandbox-1.2.3 (2005/04/29)
256
257 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
258 Do not check for (*&#$(* CXX or F77.
259
260 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
261 Do not append '/' to pathname in filter_path() if it already ends with it.
262
263 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
264 With az's help, clean up autotools to work with cross-compiling.
265
266* sandbox-1.2.2 (2005/04/28)
4 267
5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 268 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 269 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 270 have issues; bug #90592.
8 271
9* sandbox-1.2.1 272* sandbox-1.2.1 (2005/04/23)
10 273
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 274 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 275 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 276 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 277 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 278 linking with its object. Hopefully this will fix bug #90153.
16 279
17* sandbox-1.2 280* sandbox-1.2 (2005/04/23)
18 281
19 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 282 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
20 Allow lchown a symlink in write-allowed path pointing to write-denied 283 Allow lchown a symlink in write-allowed path pointing to write-denied
21 target. 284 target.
