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

5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 212 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 213 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 214 have issues; bug #90592.

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 218 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 219 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 220 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 221 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 222 linking with its object. Hopefully this will fix bug #90153.
