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

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 216 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 217 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 218 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 219 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 220 linking with its object. Hopefully this will fix bug #90153.
