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