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

10 220
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 221 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 222 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 223 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 224 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 225 linking with its object. Hopefully this will fix bug #90153.
