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