4
5 12 Sep 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
6
7 Do not handle adding working directory to SANDBOX_WRITE, as portage does it
8 itself.
9
10 04 Sep 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
11
12 Also allow symlink() system call to operate on a symlink in a writable path
13 that points to non-writable path, bug #104711.
14
15* sandbox-1.2.12 (2005/08/05)
16
17 05 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
18 sandbox.h:
19
20 Do not give an access violation if the access() system call do not have
21 write/read access - it does not actually modify, so we only need to return
22 not being able to write/read. Noted by Andres Loeh <kosmikus@gentoo.org>,
23 bug #101433.
24
25 If we are called from the command line, do not care about PORTAGE_TMPDIR,
26 and make the current directory the work directory. Also rename the variable
27 portage_tmp_dir to work_dir.
28
29 Remove the tmp_dir variable - we do not need it.
30
31 Improve error handling for get_sandbox_*_envvar() functions.
32
33 01 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
34
35 Still do normal log if debugging is requested.
36
37 Add support for SANDBOX_VERBOSE (enabled by default). Adjust SANDBOX_DEBUG
38 to only enable if equal to "1" or "yes".
39
40 Add /dev/tts to write permit, bug #42809.
41
42 27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
43 sandbox_futils.c:
44
45 Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that
46 in libsandbox .. bug #100309.
47
48 22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h:
49
50 Print all logging to stderr, bug #90343, comment #15, by Zac Medico.
51
52* sandbox-1.2.11 (2005/07/14)
53
54 14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
55 Fix getcwd, bug #98419.
56
57 08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c,
58 libsandbox.c:
59 - Try to cleanup and make error handling/printing consistent.
60 - Remove old logs if present and conflicting with current.
61 - Fix compile error with previous change, and return rather then exit().
62
63 07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
64 sandbox.h, sandbox_futils.c:
65 - Fix possible segfault in env init code.
66 - Major cleanup of sandbox_futils.c. Removed most of the functions as we now
67 write to /var/log/sandbox/, so in theory do not need all that.
68 - Redo the interface of the get_* functions so that we do not leak memory.
69 - Remove sandbox_dir and co - we are not using it anymore.
70 - Remove unused includes and variables.
71 - Only declare functions in sandbox_futils.c that are used in libsandbox.c when
72 OUTSIDE_LIBSANDBOX is not defined.
73 - Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log
74 printing's last line not honouring NOCOLOR.
75
76 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
77 libsandbox.c:
78 - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
79 write to it.
80 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
81 - Add check_prefixes() with major cleanup on check_access().
82 - Cleanup init_env_entries() and check_prefixes().
83
84 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
85 sandbox_futils.c, libsandbox.c:
86 Remove unused 'pids file' code.
87
88* sandbox-1.2.10 (2005/07/03)
89
90 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
91 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
92
93 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
94 General cleanups:
95 - Remove fooling around with exit codes - we error out on presence of a log
96 anyhow.
97 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
98 appropriate there.
99
100 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
101 Cleanup the fail_nametoolong stuff a bit more.
102
103 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
104 Remove hopefully the last ld.so.preload bits we do not use anymore.
105
106 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
107 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
108 in check_syscall(). Should speed things up a bit (at least for the getcwd()
109 and long path name test it goes down to under a second, and not 10+ seconds
110 like before). Also warn if we skip checking due to the canonicalized path
111 being too long.
112
113 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
114 More comment/readability cleanups.
115
116 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
117 sandbox_futils.c, libsandbox.c:
118 Some strncpy/strncat and other cleanups.
119
120* sandbox-1.2.9 (2005/06/09)
121
122 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
123 Move symlink hack down a bit to try and minimize on the amount of lstat()
124 calls we do.
125
126 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
127 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
128
129 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
130 Add wrapper for access() function, bug #85413.
131
132 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
133 Use generic getcwd() implementation from uclibc - should be more portable
134 and looks a bit cleaner.
135
136 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
137 Make sure our true_* pointers are initialized to NULL, and that we check for
138 all references that they are valid.
139
140 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
141 Be default we will fail if the path name we try to canonicalize is too long.
142 This however could cause issues with some things (bug #94630 and #21766), so
143 if fail_nametoolong == 0, canonicalize() will return a null length string and
144 do not fail.
145
146 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
147 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
148 make sure we re-export the new TMPDIR environment variable.
149
150 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
151 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
152 by Marcus D. Hanwell <cryos@gentoo.org>.
153
154 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
155 Add /dev/console to write list, bug #38588.
156
157* sandbox-1.2.8 (2005/05/13)
158
159 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
160 sandbox.h, sandbox_futils.c:
161 General cleanups.
162
163 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
164 sandbox.h:
165 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
166
167 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
168 sandbox.h, sandbox_futils.c:
169 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
170 to use TMPDIR if present in environment.
171
172 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
173 Remove sandbox_log_file from main() as its no longer used.
174
175 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
176 sandbox_futils.c:
177 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
178 if already exported when sandbox started). Fix get_sandbox_log() and new
179 get_sandbox_debug_log() to not use already exported environment variables if
180 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
181 SB_PATH_MAX fixes.
182
183* sandbox-1.2.7 (2005/05/12)
184
185 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
186 sandbox_futils.c:
187 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
188
189 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
190 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
191 with '(null)' in it if we did not call sandbox with absolute path.
192
193 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
194 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
195 for the child.
196
197 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
198 Remove global preload_adaptable as it is no longer used.
199
200 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
201 Rewrite environment stuff to only be set when execve'ing the child process
202 to try and avoid issues like bug #91541 that causes sandbox to crash if
203 we set LD_PRELOAD sandbox side already.
204
205 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
206 Move print_sandbox_log() up to make things neater.
207
208 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
209 Remove load_preload_libs(), as its not used anymore.
210
211 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
212 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
213
214 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
215 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
216
217 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
218 Remove ld.so.preload crap - we are not going to use it again.
219
220 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
221 Fix typo in code that checks if we got valid group information, causing a
222 segmentation fault, bug #91637.
223
224* sandbox-1.2.6 (2005/05/10)
225
226 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
227 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
228 for some odd reason, bug #91541.
229
230 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
231 Fix typo (sizeof -> strlen).
232
233 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
234 rewrote the sbcontext caching code so it accounts for env changes since lib
235 initialization.
236
237 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
238 We create libctest.c via configure, so no need to keep it around. Do some
239 cleanup related to libctest.c and libctest during configure.
240
241 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
242 Add rename support of symlinks pointing to protected files/directories.
243
244* sandbox-1.2.5 (2005/05/04)
245
246 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
247 sandbox.bashrc:
248 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
249 already set, init of the env vars fails for some reason, so do this later on,
250 and do not warn (bug #91431).
251
252 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
253 sandbox.bashrc:
254 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
255
256* sandbox-1.2.4 (2005/05/03)
257
258 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
259 Do not init the env entries with each call, as it creates too many calls to
260 lstat, etc. Should speedup things a bit, bug #91040.
261
262 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
263 Add /dev/pty to default write list. Noticed by Morfic.
264
265 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
266 sandbox.h:
267 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
268 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
269
270* sandbox-1.2.3 (2005/04/29)
271
272 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
273 Do not check for (*&#$(* CXX or F77.
274
275 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
276 Do not append '/' to pathname in filter_path() if it already ends with it.
277
278 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
279 With az's help, clean up autotools to work with cross-compiling.
280
281* sandbox-1.2.2 (2005/04/28)
282
283 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
284 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
285 have issues; bug #90592.
286
287* sandbox-1.2.1 (2005/04/23)
288
289 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
290 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
291 Make sure all functions used in libsandbox.c is declared static. Define
292 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
293 linking with its object. Hopefully this will fix bug #90153.
294
295* sandbox-1.2 (2005/04/23)
296
297 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
298 Allow lchown a symlink in write-allowed path pointing to write-denied
299 target.
300
301 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
302 Also show resolved symlink names in the log.
303
304 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
305 Seems -nostdlib was the problem with the constructor/destructor - remove it
306 from Makefile.am, and change the constructor/destructor names again.
307
308 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
309 Also rename the _init() and _fini() declarations.
310
311 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
312 Fixup the constructor/destructor function names again (they should be _init()
313 and _fini() it seems, and not being called caused sandbox_lib_path to be
314 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
315 Add both the path in given SANDBOX_x variable, as well as its symlink
316 resolved path in init_env_entries(). Modify filter_path() to be able to
317 resolve paths without resolving symlinks, as well as to be able to resolve
318 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
319 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
320 for bug #31019 cause access violations if we try to remove a symlink that is
321 not in protected path, but points to a protected path. Fix a memory leak in
322 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
323 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
324 (pid_string was uninitialized). General syntax cleanups.
325
326 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
327 infamous "pids file is not a regular file" w/out newline bug.
328
329 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
330 Correct libc_version path detection, since it was screwing up if libdir !=
331 "/lib/".
332
333 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
334 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
335
336 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
337 Fix symbols.in not added to dist.
338
339 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
340 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
341 White space fixes.
342
343 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
344 configure.in, getcwd.c, libsandbox.c, symbols.in:
345 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
346 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
347 for glibc and other libc's that use this. Update libsandbox.c to use these
348 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
349 process unset it.
350
351 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
352 killed off _init and _fini in favor of
353 void __attribute__ ((constructor)) init_func and
354 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
355
356 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
357 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
358 having the hick-ups.
359
360 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
361 Makefile.am: Fixed compilation.
4 362
5 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4: 363 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
6 Gutted the bugger so it stops checking for a c++ and fortran compiler. 364 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 365 Do *not* regenerate aclocal.m4 for making a release until a better
8 solution is created. 366 solution is created.
