4
5 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
6 sandbox_futils.c, libsandbox.c:
7 Some strncpy/strncat and other cleanups.
8
9* sandbox-1.2.9 (2005/06/09)
10
11 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
12 Move symlink hack down a bit to try and minimize on the amount of lstat()
13 calls we do.
14
15 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
16 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
17
18 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
19 Add wrapper for access() function, bug #85413.
20
21 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
22 Use generic getcwd() implementation from uclibc - should be more portable
23 and looks a bit cleaner.
24
25 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
26 Make sure our true_* pointers are initialized to NULL, and that we check for
27 all references that they are valid.
28
29 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
30 Be default we will fail if the path name we try to canonicalize is too long.
31 This however could cause issues with some things (bug #94630 and #21766), so
32 if fail_nametoolong == 0, canonicalize() will return a null length string and
33 do not fail.
34
35 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
36 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
37 make sure we re-export the new TMPDIR environment variable.
38
39 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
40 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
41 by Marcus D. Hanwell <cryos@gentoo.org>.
42
43 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
44 Add /dev/console to write list, bug #38588.
45
46* sandbox-1.2.8 (2005/05/13)
47
48 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
49 sandbox.h, sandbox_futils.c:
50 General cleanups.
51
52 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
53 sandbox.h:
54 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
55
56 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
57 sandbox.h, sandbox_futils.c:
58 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
59 to use TMPDIR if present in environment.
60
61 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
62 Remove sandbox_log_file from main() as its no longer used.
63
64 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
65 sandbox_futils.c:
66 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
67 if already exported when sandbox started). Fix get_sandbox_log() and new
68 get_sandbox_debug_log() to not use already exported environment variables if
69 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
70 SB_PATH_MAX fixes.
71
72* sandbox-1.2.7 (2005/05/12)
73
74 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
75 sandbox_futils.c:
76 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
77
78 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
79 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
80 with '(null)' in it if we did not call sandbox with absolute path.
81
82 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
83 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
84 for the child.
85
86 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
87 Remove global preload_adaptable as it is no longer used.
88
89 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
90 Rewrite environment stuff to only be set when execve'ing the child process
91 to try and avoid issues like bug #91541 that causes sandbox to crash if
92 we set LD_PRELOAD sandbox side already.
93
94 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
95 Move print_sandbox_log() up to make things neater.
96
97 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
98 Remove load_preload_libs(), as its not used anymore.
99
100 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
101 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
102
103 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
104 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
105
106 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
107 Remove ld.so.preload crap - we are not going to use it again.
108
109 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
110 Fix typo in code that checks if we got valid group information, causing a
111 segmentation fault, bug #91637.
112
113* sandbox-1.2.6 (2005/05/10)
114
115 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
116 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
117 for some odd reason, bug #91541.
118
119 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
120 Fix typo (sizeof -> strlen).
121
122 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
123 rewrote the sbcontext caching code so it accounts for env changes since lib
124 initialization.
125
126 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
127 We create libctest.c via configure, so no need to keep it around. Do some
128 cleanup related to libctest.c and libctest during configure.
129
130 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
131 Add rename support of symlinks pointing to protected files/directories.
132
133* sandbox-1.2.5 (2005/05/04)
134
135 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
136 sandbox.bashrc:
137 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
138 already set, init of the env vars fails for some reason, so do this later on,
139 and do not warn (bug #91431).
140
141 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
142 sandbox.bashrc:
143 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
144
145* sandbox-1.2.4 (2005/05/03)
146
147 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
148 Do not init the env entries with each call, as it creates too many calls to
149 lstat, etc. Should speedup things a bit, bug #91040.
150
151 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
152 Add /dev/pty to default write list. Noticed by Morfic.
153
154 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
155 sandbox.h:
156 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
157 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
158
159* sandbox-1.2.3 (2005/04/29)
160
161 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
162 Do not check for (*&#$(* CXX or F77.
163
164 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
165 Do not append '/' to pathname in filter_path() if it already ends with it.
166
167 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
168 With az's help, clean up autotools to work with cross-compiling.
169
170* sandbox-1.2.2 (2005/04/28)
4 171
5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 172 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm 173 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 174 have issues; bug #90592.

9* sandbox-1.2.1 176* sandbox-1.2.1 (2005/04/23)
10 177
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 178 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 179 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 180 Make sure all functions used in libsandbox.c is declared static. Define
14 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than 181 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 182 linking with its object. Hopefully this will fix bug #90153.
