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