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

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 204 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 205 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 206 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 207 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 208 linking with its object. Hopefully this will fix bug #90153.
