4
5 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
6 sandbox_futils.c, libsandbox.c:
7 Remove unused 'pids file' code.
8
9* sandbox-1.2.10 (2005/07/03)
10
11 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
12 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
13
14 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
15 General cleanups:
16 - Remove fooling around with exit codes - we error out on presence of a log
17 anyhow.
18 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
19 appropriate there.
20
21 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
22 Cleanup the fail_nametoolong stuff a bit more.
23
24 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
25 Remove hopefully the last ld.so.preload bits we do not use anymore.
26
27 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
28 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
29 in check_syscall(). Should speed things up a bit (at least for the getcwd()
30 and long path name test it goes down to under a second, and not 10+ seconds
31 like before). Also warn if we skip checking due to the canonicalized path
32 being too long.
33
34 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
35 More comment/readability cleanups.
36
37 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
38 sandbox_futils.c, libsandbox.c:
39 Some strncpy/strncat and other cleanups.
40
41* sandbox-1.2.9 (2005/06/09)
42
43 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
44 Move symlink hack down a bit to try and minimize on the amount of lstat()
45 calls we do.
46
47 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
48 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
49
50 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
51 Add wrapper for access() function, bug #85413.
52
53 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
54 Use generic getcwd() implementation from uclibc - should be more portable
55 and looks a bit cleaner.
56
57 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
58 Make sure our true_* pointers are initialized to NULL, and that we check for
59 all references that they are valid.
60
61 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
62 Be default we will fail if the path name we try to canonicalize is too long.
63 This however could cause issues with some things (bug #94630 and #21766), so
64 if fail_nametoolong == 0, canonicalize() will return a null length string and
65 do not fail.
66
67 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
68 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
69 make sure we re-export the new TMPDIR environment variable.
70
71 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
72 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
73 by Marcus D. Hanwell <cryos@gentoo.org>.
74
75 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
76 Add /dev/console to write list, bug #38588.
77
78* sandbox-1.2.8 (2005/05/13)
79
80 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
81 sandbox.h, sandbox_futils.c:
82 General cleanups.
83
84 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
85 sandbox.h:
86 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
87
88 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
89 sandbox.h, sandbox_futils.c:
90 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
91 to use TMPDIR if present in environment.
92
93 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
94 Remove sandbox_log_file from main() as its no longer used.
95
96 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
97 sandbox_futils.c:
98 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
99 if already exported when sandbox started). Fix get_sandbox_log() and new
100 get_sandbox_debug_log() to not use already exported environment variables if
101 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
102 SB_PATH_MAX fixes.
103
104* sandbox-1.2.7 (2005/05/12)
105
106 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
107 sandbox_futils.c:
108 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
109
110 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
111 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
112 with '(null)' in it if we did not call sandbox with absolute path.
113
114 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
115 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
116 for the child.
117
118 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
119 Remove global preload_adaptable as it is no longer used.
120
121 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
122 Rewrite environment stuff to only be set when execve'ing the child process
123 to try and avoid issues like bug #91541 that causes sandbox to crash if
124 we set LD_PRELOAD sandbox side already.
125
126 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
127 Move print_sandbox_log() up to make things neater.
128
129 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
130 Remove load_preload_libs(), as its not used anymore.
131
132 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
133 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
134
135 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
136 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
137
138 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
139 Remove ld.so.preload crap - we are not going to use it again.
140
141 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
142 Fix typo in code that checks if we got valid group information, causing a
143 segmentation fault, bug #91637.
144
145* sandbox-1.2.6 (2005/05/10)
146
147 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
148 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
149 for some odd reason, bug #91541.
150
151 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
152 Fix typo (sizeof -> strlen).
153
154 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
155 rewrote the sbcontext caching code so it accounts for env changes since lib
156 initialization.
157
158 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
159 We create libctest.c via configure, so no need to keep it around. Do some
160 cleanup related to libctest.c and libctest during configure.
161
162 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
163 Add rename support of symlinks pointing to protected files/directories.
164
165* sandbox-1.2.5 (2005/05/04)
166
167 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
168 sandbox.bashrc:
169 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
170 already set, init of the env vars fails for some reason, so do this later on,
171 and do not warn (bug #91431).
172
173 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
174 sandbox.bashrc:
175 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
176
177* sandbox-1.2.4 (2005/05/03)
178
179 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
180 Do not init the env entries with each call, as it creates too many calls to
181 lstat, etc. Should speedup things a bit, bug #91040.
182
183 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
184 Add /dev/pty to default write list. Noticed by Morfic.
185
186 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
187 sandbox.h:
188 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
189 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
190
191* sandbox-1.2.3 (2005/04/29)
192
193 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
194 Do not check for (*&#$(* CXX or F77.
195
196 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
197 Do not append '/' to pathname in filter_path() if it already ends with it.
198
199 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
200 With az's help, clean up autotools to work with cross-compiling.
201
202* sandbox-1.2.2 (2005/04/28)
203
204 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
205 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
206 have issues; bug #90592.
207
208* sandbox-1.2.1 (2005/04/23)
209
210 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
211 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
212 Make sure all functions used in libsandbox.c is declared static. Define
213 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
214 linking with its object. Hopefully this will fix bug #90153.
215
216* sandbox-1.2 (2005/04/23)
217
218 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
219 Allow lchown a symlink in write-allowed path pointing to write-denied
220 target.
221
222 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
223 Also show resolved symlink names in the log.
224
225 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
226 Seems -nostdlib was the problem with the constructor/destructor - remove it
227 from Makefile.am, and change the constructor/destructor names again.
228
229 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
230 Also rename the _init() and _fini() declarations.
231
232 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
233 Fixup the constructor/destructor function names again (they should be _init()
234 and _fini() it seems, and not being called caused sandbox_lib_path to be
235 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
236 Add both the path in given SANDBOX_x variable, as well as its symlink
237 resolved path in init_env_entries(). Modify filter_path() to be able to
238 resolve paths without resolving symlinks, as well as to be able to resolve
239 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
240 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
241 for bug #31019 cause access violations if we try to remove a symlink that is
242 not in protected path, but points to a protected path. Fix a memory leak in
243 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
244 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
245 (pid_string was uninitialized). General syntax cleanups.
246
247 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
248 infamous "pids file is not a regular file" w/out newline bug.
249
250 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
251 Correct libc_version path detection, since it was screwing up if libdir !=
252 "/lib/".
253
254 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
255 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
256
257 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
258 Fix symbols.in not added to dist.
259
260 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
261 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
262 White space fixes.
263
264 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
265 configure.in, getcwd.c, libsandbox.c, symbols.in:
266 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
267 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
268 for glibc and other libc's that use this. Update libsandbox.c to use these
269 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
270 process unset it.
271
272 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
273 killed off _init and _fini in favor of
274 void __attribute__ ((constructor)) init_func and
275 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
276
277 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
278 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
279 having the hick-ups.
280
281 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
282 Makefile.am: Fixed compilation.
4 283
5 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4: 284 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
6 Gutted the bugger so it stops checking for a c++ and fortran compiler. 285 Gutted the bugger so it stops checking for a c++ and fortran compiler.
7 Do *not* regenerate aclocal.m4 for making a release until a better 286 Do *not* regenerate aclocal.m4 for making a release until a better
8 solution is created. 287 solution is created.
