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