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