5* sandbox-1.2.9 (2005/06/09)
6
7 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
8 Move symlink hack down a bit to try and minimize on the amount of lstat()
9 calls we do.
10
11 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
12 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
13
14 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
15 Add wrapper for access() function, bug #85413.
16
17 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
18 Use generic getcwd() implementation from uclibc - should be more portable
19 and looks a bit cleaner.
20
21 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
22 Make sure our true_* pointers are initialized to NULL, and that we check for
23 all references that they are valid.
24
25 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
26 Be default we will fail if the path name we try to canonicalize is too long.
27 This however could cause issues with some things (bug #94630 and #21766), so
28 if fail_nametoolong == 0, canonicalize() will return a null length string and
29 do not fail.
30
31 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
32 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
33 make sure we re-export the new TMPDIR environment variable.
34
35 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
36 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
37 by Marcus D. Hanwell <cryos@gentoo.org>.
38
39 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
40 Add /dev/console to write list, bug #38588.
41
42* sandbox-1.2.8 (2005/05/13)
43
44 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
45 sandbox.h, sandbox_futils.c:
46 General cleanups.
47
48 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
49 sandbox.h:
50 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
51
52 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
53 sandbox.h, sandbox_futils.c:
54 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
55 to use TMPDIR if present in environment.
56
57 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
58 Remove sandbox_log_file from main() as its no longer used.
59
60 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
61 sandbox_futils.c:
62 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
63 if already exported when sandbox started). Fix get_sandbox_log() and new
64 get_sandbox_debug_log() to not use already exported environment variables if
65 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
66 SB_PATH_MAX fixes.
67
68* sandbox-1.2.7 (2005/05/12)
69
70 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
71 sandbox_futils.c:
72 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
73
74 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
75 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
76 with '(null)' in it if we did not call sandbox with absolute path.
77
78 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
79 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
80 for the child.
81
82 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
83 Remove global preload_adaptable as it is no longer used.
84
85 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
86 Rewrite environment stuff to only be set when execve'ing the child process
87 to try and avoid issues like bug #91541 that causes sandbox to crash if
88 we set LD_PRELOAD sandbox side already.
89
90 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
91 Move print_sandbox_log() up to make things neater.
92
93 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
94 Remove load_preload_libs(), as its not used anymore.
95
96 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
97 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
98
99 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
100 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
101
102 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
103 Remove ld.so.preload crap - we are not going to use it again.
104
105 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
106 Fix typo in code that checks if we got valid group information, causing a
107 segmentation fault, bug #91637.
108
109* sandbox-1.2.6 (2005/05/10)
110
111 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
112 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
113 for some odd reason, bug #91541.
114
115 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
116 Fix typo (sizeof -> strlen).
117
118 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
119 rewrote the sbcontext caching code so it accounts for env changes since lib
120 initialization.
121
122 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
123 We create libctest.c via configure, so no need to keep it around. Do some
124 cleanup related to libctest.c and libctest during configure.
125
126 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
127 Add rename support of symlinks pointing to protected files/directories.
128
129* sandbox-1.2.5 (2005/05/04)
130
131 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
132 sandbox.bashrc:
133 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
134 already set, init of the env vars fails for some reason, so do this later on,
135 and do not warn (bug #91431).
136
137 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
138 sandbox.bashrc:
139 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
140
141* sandbox-1.2.4 (2005/05/03)
142
143 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
144 Do not init the env entries with each call, as it creates too many calls to
145 lstat, etc. Should speedup things a bit, bug #91040.
146
147 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
148 Add /dev/pty to default write list. Noticed by Morfic.
149
150 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
151 sandbox.h:
152 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
153 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
154
155* sandbox-1.2.3 (2005/04/29)
156
157 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
158 Do not check for (*&#$(* CXX or F77.
159
160 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
161 Do not append '/' to pathname in filter_path() if it already ends with it.
162
163 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
164 With az's help, clean up autotools to work with cross-compiling.
165
166* sandbox-1.2.2 (2005/04/28)
167
168 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
169 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
170 have issues; bug #90592.
171
172* sandbox-1.2.1 (2005/04/23)
173
174 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
175 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
176 Make sure all functions used in libsandbox.c is declared static. Define
177 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
178 linking with its object. Hopefully this will fix bug #90153.
179
180* sandbox-1.2 (2005/04/23)
181
182 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
183 Allow lchown a symlink in write-allowed path pointing to write-denied
184 target.
185
186 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
187 Also show resolved symlink names in the log.
188
189 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
190 Seems -nostdlib was the problem with the constructor/destructor - remove it
191 from Makefile.am, and change the constructor/destructor names again.
192
193 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
194 Also rename the _init() and _fini() declarations.
195
196 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
197 Fixup the constructor/destructor function names again (they should be _init()
198 and _fini() it seems, and not being called caused sandbox_lib_path to be
199 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
200 Add both the path in given SANDBOX_x variable, as well as its symlink
201 resolved path in init_env_entries(). Modify filter_path() to be able to
202 resolve paths without resolving symlinks, as well as to be able to resolve
203 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
204 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
205 for bug #31019 cause access violations if we try to remove a symlink that is
206 not in protected path, but points to a protected path. Fix a memory leak in
207 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
208 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
209 (pid_string was uninitialized). General syntax cleanups.
210
211 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
212 infamous "pids file is not a regular file" w/out newline bug.
213
214 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
215 Correct libc_version path detection, since it was screwing up if libdir !=
216 "/lib/".
217
218 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
219 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
220
221 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
222 Fix symbols.in not added to dist.
223
224 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
225 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
226 White space fixes.
227
228 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
229 configure.in, getcwd.c, libsandbox.c, symbols.in:
230 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
231 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
232 for glibc and other libc's that use this. Update libsandbox.c to use these
233 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
234 process unset it.
235
5 01 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c: 236 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
6 killed off _init and _fini in favor of 237 killed off _init and _fini in favor of
7 void __attribute__ ((constructor)) init_func and 238 void __attribute__ ((constructor)) init_func and
8 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated. 239 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
9 240
10 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c, 241 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
