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