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

9* sandbox-1.2.1 163* sandbox-1.2.1 (2005/04/23)
10 164
11 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c, 165 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
12 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c: 166 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
13 Make sure all functions used in libsandbox.c is declared static. Define 167 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 168 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
15 linking with its object. Hopefully this will fix bug #90153. 169 linking with its object. Hopefully this will fix bug #90153.
