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