4 4
5 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
6 Make sure our true_* pointers are initialized to NULL, and that we check for
7 all references that they are valid.
8
9 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
10 Be default we will fail if the path name we try to canonicalize is too long.
11 This however could cause issues with some things (bug #94630 and #21766), so
12 if fail_nametoolong == 0, canonicalize() will return a null length string and
13 do not fail.
14
15 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
16 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
17 make sure we re-export the new TMPDIR environment variable.
18
19 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
20 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
21 by Marcus D. Hanwell <cryos@gentoo.org>.
22
23 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
24 Add /dev/console to write list, bug #38588.
25
26* sandbox-1.2.8 (2005/05/13)
27
28 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
29 sandbox.h, sandbox_futils.c:
30 General cleanups.
31
32 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
33 sandbox.h:
34 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
35
36 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
37 sandbox.h, sandbox_futils.c:
38 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
39 to use TMPDIR if present in environment.
40
41 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
42 Remove sandbox_log_file from main() as its no longer used.
43
44 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
45 sandbox_futils.c:
46 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
47 if already exported when sandbox started). Fix get_sandbox_log() and new
48 get_sandbox_debug_log() to not use already exported environment variables if
49 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
50 SB_PATH_MAX fixes.
51
52* sandbox-1.2.7 (2005/05/12)
53
54 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
55 sandbox_futils.c:
56 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
57
58 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
59 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
60 with '(null)' in it if we did not call sandbox with absolute path.
61
62 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
63 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
64 for the child.
65
66 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
67 Remove global preload_adaptable as it is no longer used.
68
69 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
70 Rewrite environment stuff to only be set when execve'ing the child process
71 to try and avoid issues like bug #91541 that causes sandbox to crash if
72 we set LD_PRELOAD sandbox side already.
73
74 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
75 Move print_sandbox_log() up to make things neater.
76
77 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
78 Remove load_preload_libs(), as its not used anymore.
79
80 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
81 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
82
83 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
84 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
85
86 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
87 Remove ld.so.preload crap - we are not going to use it again.
88
89 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
90 Fix typo in code that checks if we got valid group information, causing a
91 segmentation fault, bug #91637.
92
93* sandbox-1.2.6 (2005/05/10)
94
95 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
96 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
97 for some odd reason, bug #91541.
98
99 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
100 Fix typo (sizeof -> strlen).
101
102 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
103 rewrote the sbcontext caching code so it accounts for env changes since lib
104 initialization.
105
106 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
107 We create libctest.c via configure, so no need to keep it around. Do some
108 cleanup related to libctest.c and libctest during configure.
109
110 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
111 Add rename support of symlinks pointing to protected files/directories.
112
113* sandbox-1.2.5 (2005/05/04)
114
115 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
116 sandbox.bashrc:
117 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
118 already set, init of the env vars fails for some reason, so do this later on,
119 and do not warn (bug #91431).
120
121 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
122 sandbox.bashrc:
123 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
124
125* sandbox-1.2.4 (2005/05/03)
126
127 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
128 Do not init the env entries with each call, as it creates too many calls to
129 lstat, etc. Should speedup things a bit, bug #91040.
130
131 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
132 Add /dev/pty to default write list. Noticed by Morfic.
133
134 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
135 sandbox.h:
136 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
137 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
138
139* sandbox-1.2.3 (2005/04/29)
140
141 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
142 Do not check for (*&#$(* CXX or F77.
143
144 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
145 Do not append '/' to pathname in filter_path() if it already ends with it.
146
147 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
148 With az's help, clean up autotools to work with cross-compiling.
149
150* sandbox-1.2.2 (2005/04/28)
151
152 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
153 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
154 have issues; bug #90592.
155
156* sandbox-1.2.1 (2005/04/23)
157
158 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
159 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
160 Make sure all functions used in libsandbox.c is declared static. Define
161 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
162 linking with its object. Hopefully this will fix bug #90153.
163
164* sandbox-1.2 (2005/04/23)
165
166 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
167 Allow lchown a symlink in write-allowed path pointing to write-denied
168 target.
169
170 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
171 Also show resolved symlink names in the log.
172
173 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
174 Seems -nostdlib was the problem with the constructor/destructor - remove it
175 from Makefile.am, and change the constructor/destructor names again.
176
177 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
178 Also rename the _init() and _fini() declarations.
179
180 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
181 Fixup the constructor/destructor function names again (they should be _init()
182 and _fini() it seems, and not being called caused sandbox_lib_path to be
183 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
184 Add both the path in given SANDBOX_x variable, as well as its symlink
185 resolved path in init_env_entries(). Modify filter_path() to be able to
186 resolve paths without resolving symlinks, as well as to be able to resolve
187 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
188 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
189 for bug #31019 cause access violations if we try to remove a symlink that is
190 not in protected path, but points to a protected path. Fix a memory leak in
191 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
192 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
193 (pid_string was uninitialized). General syntax cleanups.
194
195 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
196 infamous "pids file is not a regular file" w/out newline bug.
197
198 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
199 Correct libc_version path detection, since it was screwing up if libdir !=
200 "/lib/".
201
202 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
203 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
204
205 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
206 Fix symbols.in not added to dist.
207
208 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
209 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
210 White space fixes.
211
212 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
213 configure.in, getcwd.c, libsandbox.c, symbols.in:
214 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
215 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
216 for glibc and other libc's that use this. Update libsandbox.c to use these
217 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
218 process unset it.
219
5 01 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c: 220 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
6 killed off _init and _fini in favor of 221 killed off _init and _fini in favor of
7 void __attribute__ ((constructor)) init_func and 222 void __attribute__ ((constructor)) init_func and
8 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated. 223 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
9 224
10 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c, 225 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
