4 4
5 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
6 libsandbox.c:
7 - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
8 write to it.
9 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
10
11 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
12 sandbox_futils.c, libsandbox.c:
13 Remove unused 'pids file' code.
14
15* sandbox-1.2.10 (2005/07/03)
16
17 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
18 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
19
20 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
21 General cleanups:
22 - Remove fooling around with exit codes - we error out on presence of a log
23 anyhow.
24 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
25 appropriate there.
26
27 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
28 Cleanup the fail_nametoolong stuff a bit more.
29
30 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
31 Remove hopefully the last ld.so.preload bits we do not use anymore.
32
33 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
34 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
35 in check_syscall(). Should speed things up a bit (at least for the getcwd()
36 and long path name test it goes down to under a second, and not 10+ seconds
37 like before). Also warn if we skip checking due to the canonicalized path
38 being too long.
39
40 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
41 More comment/readability cleanups.
42
43 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
44 sandbox_futils.c, libsandbox.c:
45 Some strncpy/strncat and other cleanups.
46
47* sandbox-1.2.9 (2005/06/09)
48
49 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
50 Move symlink hack down a bit to try and minimize on the amount of lstat()
51 calls we do.
52
53 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
54 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
55
56 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
57 Add wrapper for access() function, bug #85413.
58
59 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
60 Use generic getcwd() implementation from uclibc - should be more portable
61 and looks a bit cleaner.
62
63 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
64 Make sure our true_* pointers are initialized to NULL, and that we check for
65 all references that they are valid.
66
67 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
68 Be default we will fail if the path name we try to canonicalize is too long.
69 This however could cause issues with some things (bug #94630 and #21766), so
70 if fail_nametoolong == 0, canonicalize() will return a null length string and
71 do not fail.
72
73 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
74 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
75 make sure we re-export the new TMPDIR environment variable.
76
77 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
78 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
79 by Marcus D. Hanwell <cryos@gentoo.org>.
80
81 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
82 Add /dev/console to write list, bug #38588.
83
84* sandbox-1.2.8 (2005/05/13)
85
86 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
87 sandbox.h, sandbox_futils.c:
88 General cleanups.
89
90 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
91 sandbox.h:
92 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
93
94 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
95 sandbox.h, sandbox_futils.c:
96 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
97 to use TMPDIR if present in environment.
98
99 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
100 Remove sandbox_log_file from main() as its no longer used.
101
102 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
103 sandbox_futils.c:
104 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
105 if already exported when sandbox started). Fix get_sandbox_log() and new
106 get_sandbox_debug_log() to not use already exported environment variables if
107 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
108 SB_PATH_MAX fixes.
109
110* sandbox-1.2.7 (2005/05/12)
111
112 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
113 sandbox_futils.c:
114 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
115
116 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
117 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
118 with '(null)' in it if we did not call sandbox with absolute path.
119
120 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
121 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
122 for the child.
123
124 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
125 Remove global preload_adaptable as it is no longer used.
126
127 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
128 Rewrite environment stuff to only be set when execve'ing the child process
129 to try and avoid issues like bug #91541 that causes sandbox to crash if
130 we set LD_PRELOAD sandbox side already.
131
132 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
133 Move print_sandbox_log() up to make things neater.
134
135 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
136 Remove load_preload_libs(), as its not used anymore.
137
138 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
139 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
140
141 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
142 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
143
144 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
145 Remove ld.so.preload crap - we are not going to use it again.
146
147 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
148 Fix typo in code that checks if we got valid group information, causing a
149 segmentation fault, bug #91637.
150
151* sandbox-1.2.6 (2005/05/10)
152
153 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
154 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
155 for some odd reason, bug #91541.
156
157 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
158 Fix typo (sizeof -> strlen).
159
160 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
161 rewrote the sbcontext caching code so it accounts for env changes since lib
162 initialization.
163
164 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
165 We create libctest.c via configure, so no need to keep it around. Do some
166 cleanup related to libctest.c and libctest during configure.
167
168 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
169 Add rename support of symlinks pointing to protected files/directories.
170
171* sandbox-1.2.5 (2005/05/04)
172
173 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
174 sandbox.bashrc:
175 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
176 already set, init of the env vars fails for some reason, so do this later on,
177 and do not warn (bug #91431).
178
179 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
180 sandbox.bashrc:
181 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
182
183* sandbox-1.2.4 (2005/05/03)
184
185 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
186 Do not init the env entries with each call, as it creates too many calls to
187 lstat, etc. Should speedup things a bit, bug #91040.
188
189 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
190 Add /dev/pty to default write list. Noticed by Morfic.
191
192 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
193 sandbox.h:
194 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
195 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
196
197* sandbox-1.2.3 (2005/04/29)
198
199 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
200 Do not check for (*&#$(* CXX or F77.
201
202 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
203 Do not append '/' to pathname in filter_path() if it already ends with it.
204
205 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
206 With az's help, clean up autotools to work with cross-compiling.
207
208* sandbox-1.2.2 (2005/04/28)
209
210 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
211 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
212 have issues; bug #90592.
213
214* sandbox-1.2.1 (2005/04/23)
215
216 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
217 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
218 Make sure all functions used in libsandbox.c is declared static. Define
219 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
220 linking with its object. Hopefully this will fix bug #90153.
221
222* sandbox-1.2 (2005/04/23)
223
224 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
225 Allow lchown a symlink in write-allowed path pointing to write-denied
226 target.
227
228 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
229 Also show resolved symlink names in the log.
230
231 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
232 Seems -nostdlib was the problem with the constructor/destructor - remove it
233 from Makefile.am, and change the constructor/destructor names again.
234
235 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
236 Also rename the _init() and _fini() declarations.
237
238 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
239 Fixup the constructor/destructor function names again (they should be _init()
240 and _fini() it seems, and not being called caused sandbox_lib_path to be
241 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
242 Add both the path in given SANDBOX_x variable, as well as its symlink
243 resolved path in init_env_entries(). Modify filter_path() to be able to
244 resolve paths without resolving symlinks, as well as to be able to resolve
245 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
246 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
247 for bug #31019 cause access violations if we try to remove a symlink that is
248 not in protected path, but points to a protected path. Fix a memory leak in
249 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
250 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
251 (pid_string was uninitialized). General syntax cleanups.
252
253 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
254 infamous "pids file is not a regular file" w/out newline bug.
255
256 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
257 Correct libc_version path detection, since it was screwing up if libdir !=
258 "/lib/".
259
260 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
261 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
262
263 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
264 Fix symbols.in not added to dist.
265
266 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
267 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
268 White space fixes.
269
270 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
271 configure.in, getcwd.c, libsandbox.c, symbols.in:
272 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
273 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
274 for glibc and other libc's that use this. Update libsandbox.c to use these
275 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
276 process unset it.
277
5 01 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c: 278 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
6 killed off _init and _fini in favor of 279 killed off _init and _fini in favor of
7 void __attribute__ ((constructor)) init_func and 280 void __attribute__ ((constructor)) init_func and
8 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated. 281 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
9 282
10 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c, 283 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
