4
5 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
7 by Marcus D. Hanwell <cryos@gentoo.org>.
8
9 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
10 Add /dev/console to write list, bug #38588.
11
12* sandbox-1.2.8 (2005/05/13)
13
14 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
15 sandbox.h, sandbox_futils.c:
16 General cleanups.
17
18 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
19 sandbox.h:
20 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
21
22 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
23 sandbox.h, sandbox_futils.c:
24 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
25 to use TMPDIR if present in environment.
26
27 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
28 Remove sandbox_log_file from main() as its no longer used.
29
30 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
31 sandbox_futils.c:
32 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
33 if already exported when sandbox started). Fix get_sandbox_log() and new
34 get_sandbox_debug_log() to not use already exported environment variables if
35 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
36 SB_PATH_MAX fixes.
37
38* sandbox-1.2.7 (2005/05/12)
39
40 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
41 sandbox_futils.c:
42 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
43
44 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
45 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
46 with '(null)' in it if we did not call sandbox with absolute path.
47
48 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
49 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
50 for the child.
51
52 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
53 Remove global preload_adaptable as it is no longer used.
54
55 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
56 Rewrite environment stuff to only be set when execve'ing the child process
57 to try and avoid issues like bug #91541 that causes sandbox to crash if
58 we set LD_PRELOAD sandbox side already.
59
60 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
61 Move print_sandbox_log() up to make things neater.
62
63 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
64 Remove load_preload_libs(), as its not used anymore.
65
66 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
67 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
68
69 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
70 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
71
72 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
73 Remove ld.so.preload crap - we are not going to use it again.
74
75 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
76 Fix typo in code that checks if we got valid group information, causing a
77 segmentation fault, bug #91637.
78
79* sandbox-1.2.6 (2005/05/10)
80
81 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
82 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
83 for some odd reason, bug #91541.
84
85 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
86 Fix typo (sizeof -> strlen).
87
88 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
89 rewrote the sbcontext caching code so it accounts for env changes since lib
90 initialization.
91
92 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
93 We create libctest.c via configure, so no need to keep it around. Do some
94 cleanup related to libctest.c and libctest during configure.
95
96 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
97 Add rename support of symlinks pointing to protected files/directories.
98
99* sandbox-1.2.5 (2005/05/04)
100
101 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
102 sandbox.bashrc:
103 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
104 already set, init of the env vars fails for some reason, so do this later on,
105 and do not warn (bug #91431).
106
107 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
108 sandbox.bashrc:
109 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
110
111* sandbox-1.2.4 (2005/05/03)
112
113 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
114 Do not init the env entries with each call, as it creates too many calls to
115 lstat, etc. Should speedup things a bit, bug #91040.
116
117 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
118 Add /dev/pty to default write list. Noticed by Morfic.
119
120 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
121 sandbox.h:
122 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
123 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
124
125* sandbox-1.2.3 (2005/04/29)
126
127 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
128 Do not check for (*&#$(* CXX or F77.
129
130 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
131 Do not append '/' to pathname in filter_path() if it already ends with it.
132
133 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
134 With az's help, clean up autotools to work with cross-compiling.
135
136* sandbox-1.2.2 (2005/04/28)
137
138 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
139 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
140 have issues; bug #90592.
141
142* sandbox-1.2.1 (2005/04/23)
143
144 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
145 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
146 Make sure all functions used in libsandbox.c is declared static. Define
147 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
148 linking with its object. Hopefully this will fix bug #90153.
149
150* sandbox-1.2 (2005/04/23)
151
152 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
153 Allow lchown a symlink in write-allowed path pointing to write-denied
154 target.
155
156 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
157 Also show resolved symlink names in the log.
158
159 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
160 Seems -nostdlib was the problem with the constructor/destructor - remove it
161 from Makefile.am, and change the constructor/destructor names again.
162
163 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
164 Also rename the _init() and _fini() declarations.
165
166 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
167 Fixup the constructor/destructor function names again (they should be _init()
168 and _fini() it seems, and not being called caused sandbox_lib_path to be
169 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
170 Add both the path in given SANDBOX_x variable, as well as its symlink
171 resolved path in init_env_entries(). Modify filter_path() to be able to
172 resolve paths without resolving symlinks, as well as to be able to resolve
173 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
174 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
175 for bug #31019 cause access violations if we try to remove a symlink that is
176 not in protected path, but points to a protected path. Fix a memory leak in
177 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
178 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
179 (pid_string was uninitialized). General syntax cleanups.
180
181 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
182 infamous "pids file is not a regular file" w/out newline bug.
183
184 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
185 Correct libc_version path detection, since it was screwing up if libdir !=
186 "/lib/".
187
188 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
189 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
190
191 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
192 Fix symbols.in not added to dist.
193
194 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
195 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
196 White space fixes.
197
198 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
199 configure.in, getcwd.c, libsandbox.c, symbols.in:
200 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
201 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
202 for glibc and other libc's that use this. Update libsandbox.c to use these
203 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
204 process unset it.
205
206 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
207 killed off _init and _fini in favor of
208 void __attribute__ ((constructor)) init_func and
209 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
210
211 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
212 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
213 having the hick-ups.
214
215 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
216 Makefile.am: Fixed compilation.
4 217
5 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4: 218 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
6 Gutted the bugger so it stops checking for a c++ and fortran compiler. 219 Gutted the bugger so it stops checking for a c++ and fortran compiler.
7 Do *not* regenerate aclocal.m4 for making a release until a better 220 Do *not* regenerate aclocal.m4 for making a release until a better
8 solution is created. 221 solution is created.
