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

11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 199 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 200 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 201 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 202 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 203 linking with its object. Hopefully this will fix bug #90153.
