4
5 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
6 sandbox_futils.c, libsandbox.c:
7 Remove unused 'pids file' code.
8
9* sandbox-1.2.10 (2005/07/03)
10
11 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
12 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
13
14 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
15 General cleanups:
16 - Remove fooling around with exit codes - we error out on presence of a log
17 anyhow.
18 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
19 appropriate there.
20
21 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
22 Cleanup the fail_nametoolong stuff a bit more.
23
24 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
25 Remove hopefully the last ld.so.preload bits we do not use anymore.
26
27 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
28 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
29 in check_syscall(). Should speed things up a bit (at least for the getcwd()
30 and long path name test it goes down to under a second, and not 10+ seconds
31 like before). Also warn if we skip checking due to the canonicalized path
32 being too long.
33
34 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
35 More comment/readability cleanups.
36
37 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
38 sandbox_futils.c, libsandbox.c:
39 Some strncpy/strncat and other cleanups.
40
41* sandbox-1.2.9 (2005/06/09)
42
43 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
44 Move symlink hack down a bit to try and minimize on the amount of lstat()
45 calls we do.
46
47 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
48 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
49
50 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
51 Add wrapper for access() function, bug #85413.
52
53 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
54 Use generic getcwd() implementation from uclibc - should be more portable
55 and looks a bit cleaner.
56
57 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
58 Make sure our true_* pointers are initialized to NULL, and that we check for
59 all references that they are valid.
60
61 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
62 Be default we will fail if the path name we try to canonicalize is too long.
63 This however could cause issues with some things (bug #94630 and #21766), so
64 if fail_nametoolong == 0, canonicalize() will return a null length string and
65 do not fail.
66
67 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
68 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
69 make sure we re-export the new TMPDIR environment variable.
70
71 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
72 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
73 by Marcus D. Hanwell <cryos@gentoo.org>.
74
75 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
76 Add /dev/console to write list, bug #38588.
77
78* sandbox-1.2.8 (2005/05/13)
79
80 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
81 sandbox.h, sandbox_futils.c:
82 General cleanups.
83
84 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
85 sandbox.h:
86 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
87
88 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
89 sandbox.h, sandbox_futils.c:
90 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
91 to use TMPDIR if present in environment.
92
93 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
94 Remove sandbox_log_file from main() as its no longer used.
95
96 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
97 sandbox_futils.c:
98 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
99 if already exported when sandbox started). Fix get_sandbox_log() and new
100 get_sandbox_debug_log() to not use already exported environment variables if
101 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
102 SB_PATH_MAX fixes.
103
104* sandbox-1.2.7 (2005/05/12)
105
106 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
107 sandbox_futils.c:
108 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
109
110 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
111 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
112 with '(null)' in it if we did not call sandbox with absolute path.
113
114 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
115 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
116 for the child.
117
118 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
119 Remove global preload_adaptable as it is no longer used.
120
121 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
122 Rewrite environment stuff to only be set when execve'ing the child process
123 to try and avoid issues like bug #91541 that causes sandbox to crash if
124 we set LD_PRELOAD sandbox side already.
125
126 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
127 Move print_sandbox_log() up to make things neater.
128
129 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
130 Remove load_preload_libs(), as its not used anymore.
131
132 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
133 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
134
135 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
136 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
137
138 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
139 Remove ld.so.preload crap - we are not going to use it again.
140
141 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
142 Fix typo in code that checks if we got valid group information, causing a
143 segmentation fault, bug #91637.
144
145* sandbox-1.2.6 (2005/05/10)
146
147 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
148 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
149 for some odd reason, bug #91541.
150
151 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
152 Fix typo (sizeof -> strlen).
153
154 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
155 rewrote the sbcontext caching code so it accounts for env changes since lib
156 initialization.
157
158 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
159 We create libctest.c via configure, so no need to keep it around. Do some
160 cleanup related to libctest.c and libctest during configure.
161
162 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
163 Add rename support of symlinks pointing to protected files/directories.
164
165* sandbox-1.2.5 (2005/05/04)
166
167 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
168 sandbox.bashrc:
169 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
170 already set, init of the env vars fails for some reason, so do this later on,
171 and do not warn (bug #91431).
172
173 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
174 sandbox.bashrc:
175 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
176
177* sandbox-1.2.4 (2005/05/03)
178
179 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
180 Do not init the env entries with each call, as it creates too many calls to
181 lstat, etc. Should speedup things a bit, bug #91040.
182
183 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
184 Add /dev/pty to default write list. Noticed by Morfic.
185
186 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
187 sandbox.h:
188 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
189 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
190
191* sandbox-1.2.3 (2005/04/29)
192
193 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
194 Do not check for (*&#$(* CXX or F77.
195
196 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
197 Do not append '/' to pathname in filter_path() if it already ends with it.
198
199 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
200 With az's help, clean up autotools to work with cross-compiling.
201
202* sandbox-1.2.2 (2005/04/28)
4 203
5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 204 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 205 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 206 have issues; bug #90592.

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 210 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 211 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 212 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 213 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 214 linking with its object. Hopefully this will fix bug #90153.
