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