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