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

10 228
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 229 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 230 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 231 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 232 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 233 linking with its object. Hopefully this will fix bug #90153.
