4 4
5 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
6 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
7 make sure we re-export the new TMPDIR environment variable.
8
9 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
10 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
11 by Marcus D. Hanwell <cryos@gentoo.org>.
12
13 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
14 Add /dev/console to write list, bug #38588.
15
16* sandbox-1.2.8 (2005/05/13)
17
18 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
19 sandbox.h, sandbox_futils.c:
20 General cleanups.
21
22 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
23 sandbox.h:
24 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
25
26 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
27 sandbox.h, sandbox_futils.c:
28 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
29 to use TMPDIR if present in environment.
30
31 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
32 Remove sandbox_log_file from main() as its no longer used.
33
34 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
35 sandbox_futils.c:
36 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
37 if already exported when sandbox started). Fix get_sandbox_log() and new
38 get_sandbox_debug_log() to not use already exported environment variables if
39 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
40 SB_PATH_MAX fixes.
41
42* sandbox-1.2.7 (2005/05/12)
43
44 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
45 sandbox_futils.c:
46 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
47
48 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
49 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
50 with '(null)' in it if we did not call sandbox with absolute path.
51
52 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
53 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
54 for the child.
55
56 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
57 Remove global preload_adaptable as it is no longer used.
58
59 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
60 Rewrite environment stuff to only be set when execve'ing the child process
61 to try and avoid issues like bug #91541 that causes sandbox to crash if
62 we set LD_PRELOAD sandbox side already.
63
64 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
65 Move print_sandbox_log() up to make things neater.
66
67 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
68 Remove load_preload_libs(), as its not used anymore.
69
70 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
71 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
72
73 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
74 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
75
76 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
77 Remove ld.so.preload crap - we are not going to use it again.
78
79 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
80 Fix typo in code that checks if we got valid group information, causing a
81 segmentation fault, bug #91637.
82
83* sandbox-1.2.6 (2005/05/10)
84
85 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
86 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
87 for some odd reason, bug #91541.
88
89 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
90 Fix typo (sizeof -> strlen).
91
92 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
93 rewrote the sbcontext caching code so it accounts for env changes since lib
94 initialization.
95
96 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
97 We create libctest.c via configure, so no need to keep it around. Do some
98 cleanup related to libctest.c and libctest during configure.
99
100 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
101 Add rename support of symlinks pointing to protected files/directories.
102
103* sandbox-1.2.5 (2005/05/04)
104
105 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
106 sandbox.bashrc:
107 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
108 already set, init of the env vars fails for some reason, so do this later on,
109 and do not warn (bug #91431).
110
111 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
112 sandbox.bashrc:
113 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
114
115* sandbox-1.2.4 (2005/05/03)
116
117 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
118 Do not init the env entries with each call, as it creates too many calls to
119 lstat, etc. Should speedup things a bit, bug #91040.
120
121 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
122 Add /dev/pty to default write list. Noticed by Morfic.
123
124 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
125 sandbox.h:
126 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
127 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
128
129* sandbox-1.2.3 (2005/04/29)
130
131 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
132 Do not check for (*&#$(* CXX or F77.
133
134 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
135 Do not append '/' to pathname in filter_path() if it already ends with it.
136
137 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
138 With az's help, clean up autotools to work with cross-compiling.
139
140* sandbox-1.2.2 (2005/04/28)
141
142 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
143 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
144 have issues; bug #90592.
145
146* sandbox-1.2.1 (2005/04/23)
147
148 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
149 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
150 Make sure all functions used in libsandbox.c is declared static. Define
151 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
152 linking with its object. Hopefully this will fix bug #90153.
153
154* sandbox-1.2 (2005/04/23)
155
156 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
157 Allow lchown a symlink in write-allowed path pointing to write-denied
158 target.
159
160 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
161 Also show resolved symlink names in the log.
162
163 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
164 Seems -nostdlib was the problem with the constructor/destructor - remove it
165 from Makefile.am, and change the constructor/destructor names again.
166
167 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
168 Also rename the _init() and _fini() declarations.
169
170 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
171 Fixup the constructor/destructor function names again (they should be _init()
172 and _fini() it seems, and not being called caused sandbox_lib_path to be
173 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
174 Add both the path in given SANDBOX_x variable, as well as its symlink
175 resolved path in init_env_entries(). Modify filter_path() to be able to
176 resolve paths without resolving symlinks, as well as to be able to resolve
177 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
178 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
179 for bug #31019 cause access violations if we try to remove a symlink that is
180 not in protected path, but points to a protected path. Fix a memory leak in
181 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
182 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
183 (pid_string was uninitialized). General syntax cleanups.
184
185 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
186 infamous "pids file is not a regular file" w/out newline bug.
187
188 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
189 Correct libc_version path detection, since it was screwing up if libdir !=
190 "/lib/".
191
192 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
193 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
194
195 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
196 Fix symbols.in not added to dist.
197
198 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
199 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
200 White space fixes.
201
202 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
203 configure.in, getcwd.c, libsandbox.c, symbols.in:
204 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
205 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
206 for glibc and other libc's that use this. Update libsandbox.c to use these
207 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
208 process unset it.
209
5 01 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c: 210 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
6 killed off _init and _fini in favor of 211 killed off _init and _fini in favor of
7 void __attribute__ ((constructor)) init_func and 212 void __attribute__ ((constructor)) init_func and
8 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated. 213 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
9 214
10 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c, 215 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
