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

5 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4: 209 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
6 Gutted the bugger so it stops checking for a c++ and fortran compiler. 210 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 211 Do *not* regenerate aclocal.m4 for making a release until a better
8 solution is created. 212 solution is created.
