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

10 187
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 188 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 189 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 190 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 191 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 192 linking with its object. Hopefully this will fix bug #90153.
