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

5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 211 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 212 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 213 have issues; bug #90592.

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 217 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 218 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 219 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 220 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 221 linking with its object. Hopefully this will fix bug #90153.
