4
5 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
6 General cleanups:
7 - Remove fooling around with exit codes - we error out on presence of a log
8 anyhow.
9 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
10 appropriate there.
11
12 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
13 Cleanup the fail_nametoolong stuff a bit more.
14
15 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
16 Remove hopefully the last ld.so.preload bits we do not use anymore.
17
18 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
19 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
20 in check_syscall(). Should speed things up a bit (at least for the getcwd()
21 and long path name test it goes down to under a second, and not 10+ seconds
22 like before). Also warn if we skip checking due to the canonicalized path
23 being too long.
24
25 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
26 More comment/readability cleanups.
27
28 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
29 sandbox_futils.c, libsandbox.c:
30 Some strncpy/strncat and other cleanups.
31
32* sandbox-1.2.9 (2005/06/09)
33
34 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
35 Move symlink hack down a bit to try and minimize on the amount of lstat()
36 calls we do.
37
38 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
39 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
40
41 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
42 Add wrapper for access() function, bug #85413.
43
44 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
45 Use generic getcwd() implementation from uclibc - should be more portable
46 and looks a bit cleaner.
47
48 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
49 Make sure our true_* pointers are initialized to NULL, and that we check for
50 all references that they are valid.
51
52 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
53 Be default we will fail if the path name we try to canonicalize is too long.
54 This however could cause issues with some things (bug #94630 and #21766), so
55 if fail_nametoolong == 0, canonicalize() will return a null length string and
56 do not fail.
57
58 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
59 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
60 make sure we re-export the new TMPDIR environment variable.
61
62 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
63 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
64 by Marcus D. Hanwell <cryos@gentoo.org>.
65
66 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
67 Add /dev/console to write list, bug #38588.
68
69* sandbox-1.2.8 (2005/05/13)
70
71 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
72 sandbox.h, sandbox_futils.c:
73 General cleanups.
74
75 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
76 sandbox.h:
77 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
78
79 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
80 sandbox.h, sandbox_futils.c:
81 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
82 to use TMPDIR if present in environment.
83
84 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
85 Remove sandbox_log_file from main() as its no longer used.
86
87 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
88 sandbox_futils.c:
89 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
90 if already exported when sandbox started). Fix get_sandbox_log() and new
91 get_sandbox_debug_log() to not use already exported environment variables if
92 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
93 SB_PATH_MAX fixes.
94
95* sandbox-1.2.7 (2005/05/12)
96
97 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
98 sandbox_futils.c:
99 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
100
101 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
102 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
103 with '(null)' in it if we did not call sandbox with absolute path.
104
105 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
106 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
107 for the child.
108
109 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
110 Remove global preload_adaptable as it is no longer used.
111
112 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
113 Rewrite environment stuff to only be set when execve'ing the child process
114 to try and avoid issues like bug #91541 that causes sandbox to crash if
115 we set LD_PRELOAD sandbox side already.
116
117 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
118 Move print_sandbox_log() up to make things neater.
119
120 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
121 Remove load_preload_libs(), as its not used anymore.
122
123 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
124 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
125
126 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
127 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
128
129 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
130 Remove ld.so.preload crap - we are not going to use it again.
131
132 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
133 Fix typo in code that checks if we got valid group information, causing a
134 segmentation fault, bug #91637.
135
136* sandbox-1.2.6 (2005/05/10)
137
138 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
139 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
140 for some odd reason, bug #91541.
141
142 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
143 Fix typo (sizeof -> strlen).
144
145 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
146 rewrote the sbcontext caching code so it accounts for env changes since lib
147 initialization.
148
149 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
150 We create libctest.c via configure, so no need to keep it around. Do some
151 cleanup related to libctest.c and libctest during configure.
152
153 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
154 Add rename support of symlinks pointing to protected files/directories.
155
156* sandbox-1.2.5 (2005/05/04)
157
158 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
159 sandbox.bashrc:
160 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
161 already set, init of the env vars fails for some reason, so do this later on,
162 and do not warn (bug #91431).
163
164 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
165 sandbox.bashrc:
166 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
167
168* sandbox-1.2.4 (2005/05/03)
169
170 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
171 Do not init the env entries with each call, as it creates too many calls to
172 lstat, etc. Should speedup things a bit, bug #91040.
173
174 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
175 Add /dev/pty to default write list. Noticed by Morfic.
176
177 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
178 sandbox.h:
179 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
180 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
181
182* sandbox-1.2.3 (2005/04/29)
183
184 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
185 Do not check for (*&#$(* CXX or F77.
186
187 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
188 Do not append '/' to pathname in filter_path() if it already ends with it.
189
190 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
191 With az's help, clean up autotools to work with cross-compiling.
192
193* sandbox-1.2.2 (2005/04/28)
4 194
5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 195 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 196 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 197 have issues; bug #90592.

12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 202 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 203 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 204 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 205 linking with its object. Hopefully this will fix bug #90153.
