5 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6 Move symlink hack down a bit to try and minimize on the amount of lstat()
7 calls we do.
8
9 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
10 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
11
12 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
13 Add wrapper for access() function, bug #85413.
14
15 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
16 Use generic getcwd() implementation from uclibc - should be more portable
17 and looks a bit cleaner.
18
19 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
20 Make sure our true_* pointers are initialized to NULL, and that we check for
21 all references that they are valid.
22
23 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
24 Be default we will fail if the path name we try to canonicalize is too long.
25 This however could cause issues with some things (bug #94630 and #21766), so
26 if fail_nametoolong == 0, canonicalize() will return a null length string and
27 do not fail.
28
29 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
30 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
31 make sure we re-export the new TMPDIR environment variable.
32
33 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
34 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
35 by Marcus D. Hanwell <cryos@gentoo.org>.
36
37 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
38 Add /dev/console to write list, bug #38588.
39
40* sandbox-1.2.8 (2005/05/13)
41
42 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
43 sandbox.h, sandbox_futils.c:
44 General cleanups.
45
46 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
47 sandbox.h:
48 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
49
50 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
51 sandbox.h, sandbox_futils.c:
52 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
53 to use TMPDIR if present in environment.
54
55 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
56 Remove sandbox_log_file from main() as its no longer used.
57
58 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
59 sandbox_futils.c:
60 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
61 if already exported when sandbox started). Fix get_sandbox_log() and new
62 get_sandbox_debug_log() to not use already exported environment variables if
63 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
64 SB_PATH_MAX fixes.
65
66* sandbox-1.2.7 (2005/05/12)
67
68 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
69 sandbox_futils.c:
70 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
71
72 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
73 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
74 with '(null)' in it if we did not call sandbox with absolute path.
75
76 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
77 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
78 for the child.
79
80 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
81 Remove global preload_adaptable as it is no longer used.
82
83 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
84 Rewrite environment stuff to only be set when execve'ing the child process
85 to try and avoid issues like bug #91541 that causes sandbox to crash if
86 we set LD_PRELOAD sandbox side already.
87
88 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
89 Move print_sandbox_log() up to make things neater.
90
91 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
92 Remove load_preload_libs(), as its not used anymore.
93
94 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
95 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
96
97 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
98 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
99
100 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
101 Remove ld.so.preload crap - we are not going to use it again.
102
103 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
104 Fix typo in code that checks if we got valid group information, causing a
105 segmentation fault, bug #91637.
106
107* sandbox-1.2.6 (2005/05/10)
108
109 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
110 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
111 for some odd reason, bug #91541.
112
113 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
114 Fix typo (sizeof -> strlen).
115
116 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
117 rewrote the sbcontext caching code so it accounts for env changes since lib
118 initialization.
119
120 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
121 We create libctest.c via configure, so no need to keep it around. Do some
122 cleanup related to libctest.c and libctest during configure.
123
124 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
125 Add rename support of symlinks pointing to protected files/directories.
126
127* sandbox-1.2.5 (2005/05/04)
128
129 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
130 sandbox.bashrc:
131 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
132 already set, init of the env vars fails for some reason, so do this later on,
133 and do not warn (bug #91431).
134
135 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
136 sandbox.bashrc:
137 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
138
139* sandbox-1.2.4 (2005/05/03)
140
141 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
142 Do not init the env entries with each call, as it creates too many calls to
143 lstat, etc. Should speedup things a bit, bug #91040.
144
145 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
146 Add /dev/pty to default write list. Noticed by Morfic.
147
148 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
149 sandbox.h:
150 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
151 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
152
153* sandbox-1.2.3 (2005/04/29)
154
155 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
156 Do not check for (*&#$(* CXX or F77.
157
158 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
159 Do not append '/' to pathname in filter_path() if it already ends with it.
160
161 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
162 With az's help, clean up autotools to work with cross-compiling.
163
164* sandbox-1.2.2 (2005/04/28)
4 165
5 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c: 166 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 167 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
7 have issues; bug #90592. 168 have issues; bug #90592.
8 169
9* sandbox-1.2.1 170* sandbox-1.2.1 (2005/04/23)
10 171
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 172 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 173 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 174 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 175 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 176 linking with its object. Hopefully this will fix bug #90153.
