4
5 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6 More comment/readability cleanups.
7
8 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
9 sandbox_futils.c, libsandbox.c:
10 Some strncpy/strncat and other cleanups.
11
12* sandbox-1.2.9 (2005/06/09)
13
14 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
15 Move symlink hack down a bit to try and minimize on the amount of lstat()
16 calls we do.
17
18 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
19 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
20
21 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
22 Add wrapper for access() function, bug #85413.
23
24 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
25 Use generic getcwd() implementation from uclibc - should be more portable
26 and looks a bit cleaner.
27
28 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
29 Make sure our true_* pointers are initialized to NULL, and that we check for
30 all references that they are valid.
31
32 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
33 Be default we will fail if the path name we try to canonicalize is too long.
34 This however could cause issues with some things (bug #94630 and #21766), so
35 if fail_nametoolong == 0, canonicalize() will return a null length string and
36 do not fail.
37
38 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
39 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
40 make sure we re-export the new TMPDIR environment variable.
41
42 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
43 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
44 by Marcus D. Hanwell <cryos@gentoo.org>.
45
46 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
47 Add /dev/console to write list, bug #38588.
48
49* sandbox-1.2.8 (2005/05/13)
50
51 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
52 sandbox.h, sandbox_futils.c:
53 General cleanups.
54
55 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
56 sandbox.h:
57 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
58
59 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
60 sandbox.h, sandbox_futils.c:
61 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
62 to use TMPDIR if present in environment.
63
64 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
65 Remove sandbox_log_file from main() as its no longer used.
66
67 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
68 sandbox_futils.c:
69 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
70 if already exported when sandbox started). Fix get_sandbox_log() and new
71 get_sandbox_debug_log() to not use already exported environment variables if
72 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
73 SB_PATH_MAX fixes.
74
75* sandbox-1.2.7 (2005/05/12)
76
77 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
78 sandbox_futils.c:
79 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
80
81 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
82 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
83 with '(null)' in it if we did not call sandbox with absolute path.
84
85 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
86 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
87 for the child.
88
89 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
90 Remove global preload_adaptable as it is no longer used.
91
92 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
93 Rewrite environment stuff to only be set when execve'ing the child process
94 to try and avoid issues like bug #91541 that causes sandbox to crash if
95 we set LD_PRELOAD sandbox side already.
96
97 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
98 Move print_sandbox_log() up to make things neater.
99
100 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
101 Remove load_preload_libs(), as its not used anymore.
102
103 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
104 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
105
106 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
107 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
108
109 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
110 Remove ld.so.preload crap - we are not going to use it again.
111
112 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
113 Fix typo in code that checks if we got valid group information, causing a
114 segmentation fault, bug #91637.
115
116* sandbox-1.2.6 (2005/05/10)
117
118 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
119 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
120 for some odd reason, bug #91541.
121
122 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
123 Fix typo (sizeof -> strlen).
124
125 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
126 rewrote the sbcontext caching code so it accounts for env changes since lib
127 initialization.
128
129 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
130 We create libctest.c via configure, so no need to keep it around. Do some
131 cleanup related to libctest.c and libctest during configure.
132
133 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
134 Add rename support of symlinks pointing to protected files/directories.
135
136* sandbox-1.2.5 (2005/05/04)
137
138 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
139 sandbox.bashrc:
140 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
141 already set, init of the env vars fails for some reason, so do this later on,
142 and do not warn (bug #91431).
143
144 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
145 sandbox.bashrc:
146 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
147
148* sandbox-1.2.4 (2005/05/03)
149
150 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
151 Do not init the env entries with each call, as it creates too many calls to
152 lstat, etc. Should speedup things a bit, bug #91040.
153
154 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
155 Add /dev/pty to default write list. Noticed by Morfic.
156
157 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
158 sandbox.h:
159 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
160 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
161
162* sandbox-1.2.3 (2005/04/29)
163
164 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
165 Do not check for (*&#$(* CXX or F77.
166
167 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
168 Do not append '/' to pathname in filter_path() if it already ends with it.
169
170 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
171 With az's help, clean up autotools to work with cross-compiling.
172
173* sandbox-1.2.2 (2005/04/28)
4 174
5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 175 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 176 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 177 have issues; bug #90592.

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 181 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 182 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 183 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 184 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 185 linking with its object. Hopefully this will fix bug #90153.
