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

10 214
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 215 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 216 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 217 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 218 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 219 linking with its object. Hopefully this will fix bug #90153.
