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