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