5* sandbox-1.2.10 (2005/07/03)
6
7 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
8 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
9
10 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
11 General cleanups:
12 - Remove fooling around with exit codes - we error out on presence of a log
13 anyhow.
14 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
15 appropriate there.
16
17 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
18 Cleanup the fail_nametoolong stuff a bit more.
19
20 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
21 Remove hopefully the last ld.so.preload bits we do not use anymore.
22
23 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
24 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
25 in check_syscall(). Should speed things up a bit (at least for the getcwd()
26 and long path name test it goes down to under a second, and not 10+ seconds
27 like before). Also warn if we skip checking due to the canonicalized path
28 being too long.
29
30 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
31 More comment/readability cleanups.
32
33 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
34 sandbox_futils.c, libsandbox.c:
35 Some strncpy/strncat and other cleanups.
36
37* sandbox-1.2.9 (2005/06/09)
38
39 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
40 Move symlink hack down a bit to try and minimize on the amount of lstat()
41 calls we do.
42
43 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
44 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
45
46 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
47 Add wrapper for access() function, bug #85413.
48
49 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
50 Use generic getcwd() implementation from uclibc - should be more portable
51 and looks a bit cleaner.
52
53 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
54 Make sure our true_* pointers are initialized to NULL, and that we check for
55 all references that they are valid.
56
57 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
58 Be default we will fail if the path name we try to canonicalize is too long.
59 This however could cause issues with some things (bug #94630 and #21766), so
60 if fail_nametoolong == 0, canonicalize() will return a null length string and
61 do not fail.
62
63 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
64 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
65 make sure we re-export the new TMPDIR environment variable.
66
67 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
68 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
69 by Marcus D. Hanwell <cryos@gentoo.org>.
70
71 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
72 Add /dev/console to write list, bug #38588.
73
74* sandbox-1.2.8 (2005/05/13)
75
76 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
77 sandbox.h, sandbox_futils.c:
78 General cleanups.
79
80 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
81 sandbox.h:
82 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
83
84 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
85 sandbox.h, sandbox_futils.c:
86 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
87 to use TMPDIR if present in environment.
88
89 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
90 Remove sandbox_log_file from main() as its no longer used.
91
92 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
93 sandbox_futils.c:
94 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
95 if already exported when sandbox started). Fix get_sandbox_log() and new
96 get_sandbox_debug_log() to not use already exported environment variables if
97 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
98 SB_PATH_MAX fixes.
99
100* sandbox-1.2.7 (2005/05/12)
101
102 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
103 sandbox_futils.c:
104 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
105
106 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
107 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
108 with '(null)' in it if we did not call sandbox with absolute path.
109
110 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
111 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
112 for the child.
113
114 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
115 Remove global preload_adaptable as it is no longer used.
116
117 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
118 Rewrite environment stuff to only be set when execve'ing the child process
119 to try and avoid issues like bug #91541 that causes sandbox to crash if
120 we set LD_PRELOAD sandbox side already.
121
122 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
123 Move print_sandbox_log() up to make things neater.
124
125 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
126 Remove load_preload_libs(), as its not used anymore.
127
128 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
129 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
130
131 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
132 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
133
134 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
135 Remove ld.so.preload crap - we are not going to use it again.
136
137 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
138 Fix typo in code that checks if we got valid group information, causing a
139 segmentation fault, bug #91637.
140
141* sandbox-1.2.6 (2005/05/10)
142
143 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
144 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
145 for some odd reason, bug #91541.
146
147 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
148 Fix typo (sizeof -> strlen).
149
150 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
151 rewrote the sbcontext caching code so it accounts for env changes since lib
152 initialization.
153
154 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
155 We create libctest.c via configure, so no need to keep it around. Do some
156 cleanup related to libctest.c and libctest during configure.
157
158 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
159 Add rename support of symlinks pointing to protected files/directories.
160
161* sandbox-1.2.5 (2005/05/04)
162
163 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
164 sandbox.bashrc:
165 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
166 already set, init of the env vars fails for some reason, so do this later on,
167 and do not warn (bug #91431).
168
169 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
170 sandbox.bashrc:
171 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
172
173* sandbox-1.2.4 (2005/05/03)
174
175 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
176 Do not init the env entries with each call, as it creates too many calls to
177 lstat, etc. Should speedup things a bit, bug #91040.
178
179 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
180 Add /dev/pty to default write list. Noticed by Morfic.
181
182 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
183 sandbox.h:
184 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
185 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
186
187* sandbox-1.2.3 (2005/04/29)
188
189 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
190 Do not check for (*&#$(* CXX or F77.
191
192 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
193 Do not append '/' to pathname in filter_path() if it already ends with it.
194
195 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
196 With az's help, clean up autotools to work with cross-compiling.
197
198* sandbox-1.2.2 (2005/04/28)
199
200 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
201 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
202 have issues; bug #90592.
203
204* sandbox-1.2.1 (2005/04/23)
205
206 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
207 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
208 Make sure all functions used in libsandbox.c is declared static. Define
209 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
210 linking with its object. Hopefully this will fix bug #90153.
211
212* sandbox-1.2 (2005/04/23)
213
214 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
215 Allow lchown a symlink in write-allowed path pointing to write-denied
216 target.
217
218 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
219 Also show resolved symlink names in the log.
220
221 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
222 Seems -nostdlib was the problem with the constructor/destructor - remove it
223 from Makefile.am, and change the constructor/destructor names again.
224
225 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
226 Also rename the _init() and _fini() declarations.
227
228 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
229 Fixup the constructor/destructor function names again (they should be _init()
230 and _fini() it seems, and not being called caused sandbox_lib_path to be
231 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
232 Add both the path in given SANDBOX_x variable, as well as its symlink
233 resolved path in init_env_entries(). Modify filter_path() to be able to
234 resolve paths without resolving symlinks, as well as to be able to resolve
235 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
236 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
237 for bug #31019 cause access violations if we try to remove a symlink that is
238 not in protected path, but points to a protected path. Fix a memory leak in
239 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
240 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
241 (pid_string was uninitialized). General syntax cleanups.
242
243 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
244 infamous "pids file is not a regular file" w/out newline bug.
245
246 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
247 Correct libc_version path detection, since it was screwing up if libdir !=
248 "/lib/".
249
250 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
251 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
252
253 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
254 Fix symbols.in not added to dist.
255
256 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
257 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
258 White space fixes.
259
260 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
261 configure.in, getcwd.c, libsandbox.c, symbols.in:
262 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
263 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
264 for glibc and other libc's that use this. Update libsandbox.c to use these
265 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
266 process unset it.
267
268 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
269 killed off _init and _fini in favor of
270 void __attribute__ ((constructor)) init_func and
271 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
272
273 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
274 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
275 having the hick-ups.
276
277 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
278 Makefile.am: Fixed compilation.
4 279
5 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4: 280 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
6 Gutted the bugger so it stops checking for a c++ and fortran compiler. 281 Gutted the bugger so it stops checking for a c++ and fortran compiler.
7 Do *not* regenerate aclocal.m4 for making a release until a better 282 Do *not* regenerate aclocal.m4 for making a release until a better
