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