3 # $Header$
4
5 28 Nov 2005 Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
6 sandbox.c, sandbox.h, sandbox.bashrc:
7
8 Check generic getcwd()'s return as well for validity, bug #101728.
9
10 Cleanup environ variables.
11
12 Rather check SANDBOX_ACTIVE if we are already running. Set SANDBOX_ACTIVE
13 to readonly in sandbox.bashrc.
14
15 Make sure we use our bashrc.
16
17 01 Nov 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
18
19 Do not pass mode to true_open and true_open64 if not needed. Should fix a
20 segfault in some cases.
21
22 * sandbox-1.2.13 (2005/09/12)
23
24 12 Sep 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, libsandbox.c:
25
26 Do not handle adding working directory to SANDBOX_WRITE, as portage does it
27 itself.
28
29 Make libsb_fini() do cleanup a bit more complete just in case we get another
30 uClibc 'call preloaded library fini before that of app' issue ... probably
31 will not help much, but we try.
32
33 04 Sep 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
34
35 Also allow symlink() system call to operate on a symlink in a writable path
36 that points to non-writable path, bug #104711.
37
38 * sandbox-1.2.12 (2005/08/05)
39
40 05 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
41 sandbox.h:
42
43 Do not give an access violation if the access() system call do not have
44 write/read access - it does not actually modify, so we only need to return
45 not being able to write/read. Noted by Andres Loeh <kosmikus@gentoo.org>,
46 bug #101433.
47
48 If we are called from the command line, do not care about PORTAGE_TMPDIR,
49 and make the current directory the work directory. Also rename the variable
50 portage_tmp_dir to work_dir.
51
52 Remove the tmp_dir variable - we do not need it.
53
54 Improve error handling for get_sandbox_*_envvar() functions.
55
56 01 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
57
58 Still do normal log if debugging is requested.
59
60 Add support for SANDBOX_VERBOSE (enabled by default). Adjust SANDBOX_DEBUG
61 to only enable if equal to "1" or "yes".
62
63 Add /dev/tts to write permit, bug #42809.
64
65 27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
66 sandbox_futils.c:
67
68 Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that
69 in libsandbox .. bug #100309.
70
71 22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h:
72
73 Print all logging to stderr, bug #90343, comment #15, by Zac Medico.
74
75 * sandbox-1.2.11 (2005/07/14)
76
77 14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
78 Fix getcwd, bug #98419.
79
80 08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c,
81 libsandbox.c:
82 - Try to cleanup and make error handling/printing consistent.
83 - Remove old logs if present and conflicting with current.
84 - Fix compile error with previous change, and return rather then exit().
85
86 07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
87 sandbox.h, sandbox_futils.c:
88 - Fix possible segfault in env init code.
89 - Major cleanup of sandbox_futils.c. Removed most of the functions as we now
90 write to /var/log/sandbox/, so in theory do not need all that.
91 - Redo the interface of the get_* functions so that we do not leak memory.
92 - Remove sandbox_dir and co - we are not using it anymore.
93 - Remove unused includes and variables.
94 - Only declare functions in sandbox_futils.c that are used in libsandbox.c when
95 OUTSIDE_LIBSANDBOX is not defined.
96 - Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log
97 printing's last line not honouring NOCOLOR.
98
99 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
100 libsandbox.c:
101 - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
102 write to it.
103 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
104 - Add check_prefixes() with major cleanup on check_access().
105 - Cleanup init_env_entries() and check_prefixes().
106
107 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
108 sandbox_futils.c, libsandbox.c:
109 Remove unused 'pids file' code.
110
111 * sandbox-1.2.10 (2005/07/03)
112
113 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
114 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
115
116 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
117 General cleanups:
118 - Remove fooling around with exit codes - we error out on presence of a log
119 anyhow.
120 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
121 appropriate there.
122
123 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
124 Cleanup the fail_nametoolong stuff a bit more.
125
126 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
127 Remove hopefully the last ld.so.preload bits we do not use anymore.
128
129 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
130 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
131 in check_syscall(). Should speed things up a bit (at least for the getcwd()
132 and long path name test it goes down to under a second, and not 10+ seconds
133 like before). Also warn if we skip checking due to the canonicalized path
134 being too long.
135
136 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
137 More comment/readability cleanups.
138
139 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
140 sandbox_futils.c, libsandbox.c:
141 Some strncpy/strncat and other cleanups.
142
143 * sandbox-1.2.9 (2005/06/09)
144
145 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
146 Move symlink hack down a bit to try and minimize on the amount of lstat()
147 calls we do.
148
149 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
150 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
151
152 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
153 Add wrapper for access() function, bug #85413.
154
155 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
156 Use generic getcwd() implementation from uclibc - should be more portable
157 and looks a bit cleaner.
158
159 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
160 Make sure our true_* pointers are initialized to NULL, and that we check for
161 all references that they are valid.
162
163 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
164 Be default we will fail if the path name we try to canonicalize is too long.
165 This however could cause issues with some things (bug #94630 and #21766), so
166 if fail_nametoolong == 0, canonicalize() will return a null length string and
167 do not fail.
168
169 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
170 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
171 make sure we re-export the new TMPDIR environment variable.
172
173 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
174 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
175 by Marcus D. Hanwell <cryos@gentoo.org>.
176
177 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
178 Add /dev/console to write list, bug #38588.
179
180 * sandbox-1.2.8 (2005/05/13)
181
182 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
183 sandbox.h, sandbox_futils.c:
184 General cleanups.
185
186 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
187 sandbox.h:
188 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
189
190 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
191 sandbox.h, sandbox_futils.c:
192 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
193 to use TMPDIR if present in environment.
194
195 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
196 Remove sandbox_log_file from main() as its no longer used.
197
198 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
199 sandbox_futils.c:
200 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
201 if already exported when sandbox started). Fix get_sandbox_log() and new
202 get_sandbox_debug_log() to not use already exported environment variables if
203 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
204 SB_PATH_MAX fixes.
205
206 * sandbox-1.2.7 (2005/05/12)
207
208 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
209 sandbox_futils.c:
210 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
211
212 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
213 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
214 with '(null)' in it if we did not call sandbox with absolute path.
215
216 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
217 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
218 for the child.
219
220 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
221 Remove global preload_adaptable as it is no longer used.
222
223 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
224 Rewrite environment stuff to only be set when execve'ing the child process
225 to try and avoid issues like bug #91541 that causes sandbox to crash if
226 we set LD_PRELOAD sandbox side already.
227
228 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
229 Move print_sandbox_log() up to make things neater.
230
231 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
232 Remove load_preload_libs(), as its not used anymore.
233
234 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
235 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
236
237 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
238 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
239
240 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
241 Remove ld.so.preload crap - we are not going to use it again.
242
243 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
244 Fix typo in code that checks if we got valid group information, causing a
245 segmentation fault, bug #91637.
246
247 * sandbox-1.2.6 (2005/05/10)
248
249 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
250 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
251 for some odd reason, bug #91541.
252
253 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
254 Fix typo (sizeof -> strlen).
255
256 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
257 rewrote the sbcontext caching code so it accounts for env changes since lib
258 initialization.
259
260 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
261 We create libctest.c via configure, so no need to keep it around. Do some
262 cleanup related to libctest.c and libctest during configure.
263
264 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
265 Add rename support of symlinks pointing to protected files/directories.
266
267 * sandbox-1.2.5 (2005/05/04)
268
269 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
270 sandbox.bashrc:
271 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
272 already set, init of the env vars fails for some reason, so do this later on,
273 and do not warn (bug #91431).
274
275 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
276 sandbox.bashrc:
277 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
278
279 * sandbox-1.2.4 (2005/05/03)
280
281 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
282 Do not init the env entries with each call, as it creates too many calls to
283 lstat, etc. Should speedup things a bit, bug #91040.
284
285 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
286 Add /dev/pty to default write list. Noticed by Morfic.
287
288 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
289 sandbox.h:
290 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
291 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
292
293 * sandbox-1.2.3 (2005/04/29)
294
295 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
296 Do not check for (*&#$(* CXX or F77.
297
298 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
299 Do not append '/' to pathname in filter_path() if it already ends with it.
300
301 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
302 With az's help, clean up autotools to work with cross-compiling.
303
304 * sandbox-1.2.2 (2005/04/28)
305
306 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
307 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
308 have issues; bug #90592.
309
310 * sandbox-1.2.1 (2005/04/23)
311
312 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
313 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
314 Make sure all functions used in libsandbox.c is declared static. Define
315 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
316 linking with its object. Hopefully this will fix bug #90153.
317
318 * sandbox-1.2 (2005/04/23)
319
320 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
321 Allow lchown a symlink in write-allowed path pointing to write-denied
322 target.
323
324 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
325 Also show resolved symlink names in the log.
326
327 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
328 Seems -nostdlib was the problem with the constructor/destructor - remove it
329 from Makefile.am, and change the constructor/destructor names again.
330
331 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
332 Also rename the _init() and _fini() declarations.
333
334 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
335 Fixup the constructor/destructor function names again (they should be _init()
336 and _fini() it seems, and not being called caused sandbox_lib_path to be
337 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
338 Add both the path in given SANDBOX_x variable, as well as its symlink
339 resolved path in init_env_entries(). Modify filter_path() to be able to
340 resolve paths without resolving symlinks, as well as to be able to resolve
341 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
342 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
343 for bug #31019 cause access violations if we try to remove a symlink that is
344 not in protected path, but points to a protected path. Fix a memory leak in
345 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
346 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
347 (pid_string was uninitialized). General syntax cleanups.
348
349 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
350 infamous "pids file is not a regular file" w/out newline bug.
351
352 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
353 Correct libc_version path detection, since it was screwing up if libdir !=
354 "/lib/".
355
356 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
357 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
358
359 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
360 Fix symbols.in not added to dist.
361
362 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
363 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
364 White space fixes.
365
366 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
367 configure.in, getcwd.c, libsandbox.c, symbols.in:
368 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
369 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
370 for glibc and other libc's that use this. Update libsandbox.c to use these
371 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
372 process unset it.
373
374 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
375 killed off _init and _fini in favor of
376 void __attribute__ ((constructor)) init_func and
377 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
378
379 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
380 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
381 having the hick-ups.
382
383 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
384 Makefile.am: Fixed compilation.
385
386 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
387 Gutted the bugger so it stops checking for a c++ and fortran compiler.
388 Do *not* regenerate aclocal.m4 for making a release until a better
389 solution is created.
390
391 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
392 Removal of more hardcoded paths.
393
394 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
395 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
396
397 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
398 Sandbox is now autotooled, create-localdecls needs to be killed and the code
399 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
400 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
401 To get to a point of testing, automake && autoconf; created requisite files w/
402 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
403 /lib and /usr/lib/portage/bin.
404
405 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
406 closing out bug #70225, potential overflow of the sandbox_pids_file var.
407
408 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
409 (think it was at least) allows intermixing of code and data segments. bug #70351
410 should be fixed by this.
411
412 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
413 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
414
415 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
416 Seth Robertson that tracked down all adjuct flags for read operations that
417 do not invoke a write operation.
418
419 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
420 Another fix from jstubbs regarding a free() on a stack variable for the
421 environment -- tracking now prevents extraneous free()'s segfault.
422
423 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
424 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
425 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
426 Also remove the errno = ESUCCESS settings as documentation points out that
427 a library isn't allowed to do that.
428
429 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
430 file_security_check() function to check random potential exploits on files
431 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
432 the 'system-crippling' exploits (bug 21923) and catches a few other
433 potential problems.
434
435 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
436 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
437
438 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
439 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
440 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
441
442 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
443 Fix permissions and group of pids file and logs. Permissions should be 0664
444 and group should be 'portage'. Bug #34260.
445
446 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
447 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
448 to the real execve (in our execve wrapper). Seems that on some arches (sparc
449 among others) do not allow us to tamper with the readonly copy passed to
450 execve, so pass our own copy of the environment. Bug #42290.
451
452 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
453 Changed tail to head and added a notice about duration of glibc check.
454
455 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
456 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
457 as there isn't a guarentee that it is dynamic.
458
459 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
460 If 'file' passed to before_syscall(const char *func, const char *file) is
461 invalid, we should set errno to ENOENT, and not EINVAL. This should
462 close bug #32238.
463
464 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
465 Fix a bug that occurs mainly on 64bit arch, where the file passed to
466 the functions we wrap, is invalid, and then cause canonicalize to pass
467 garbage to before_syscall(), thanks to great detective work from
468 Andrea Luzzardi <al@sig11.org> (bug #29846).
469
470 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
471 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
472
473 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
474 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
475 only checked the destination patch, and not the source, so we could move
476 a protected file to a unprotected directory, and then delete/modify it.
477 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
478
479 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
480 Added python2.3 to the predict section/variable.
481
482 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
483 sandbox.h, sandbox_futils.c :
484 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
485 it is not set, it will revert to its old value.
486
487 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
488 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
489 rather than failing with a violation, bug #29748.
490
491 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
492 Fix canonicalize() to ignore calls with path = "".
493
494 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
495 sandbox_futils.c, canonicalize.c :
496 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
497 call handled strings larger than PATH_MAX (bug #21766). It however does not
498 work the same on 2.4 kernels.
499
500 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
501 do not need the system call. We use the default getcwd() function via a
502 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
503 means the current directory was removed, OR that the the system call for
504 getcwd failed (curious is that it do not fail and return NULL or set
505 errno, but rather just truncate the retured directory - usually from the
506 start), and if so, we use the generic getcwd() function (__egetcwd). Note
507 that we do not use the generic version all the time, as it calls lstat()
508 a great number of times, and performance degrade much.
509
510 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
511 libsandbox.c :
512 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
513
514 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
515 create-localdecls :
516 When checking path names of files accessed, we need to canonicalize it, else
517 it may be a symlink in a 'write allowed' directory pointing to a file in a
518 directory we should not have write access to.
519
520 With something like coreutils-5.0, we have two problems:
521 1) One of the tests checks if getcwd() can return a path longer than
522 PATH_MAX. This test then tries to create a dir which even while
523 created local (mkdir("conftest2")), it ends up being resolved with
524 a name that is much larger than PATH_MAX. The problem now is that
525 canonicalize() have undefined behaviour when the path was too long
526 (returned wrongly truncated paths, etc), and pass the wrong path to
527 before_syscall() (causing the bogus sandbox violations).
528 2) The ecanonicalize() function we used, along with the canonicalize()
529 function did not support longer than PATH_MAX. This is partly a
530 cause for 1), but the error checking (rather lack of it) of calls
531 to erealpath() in canonicalize() was the prime reason for 1).
532
533 As we do not use this canonicalized name to call the function, we resolve this
534 by fixing canonicalize() to do better error checking, and ecanonicalize() as
535 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
536 While they will resolve paths properly now, and can check if a write/read is
537 allowed, the functions called from the sandboxed environment will still work
538 as expected.
539
540 This should resolve bug #21766.
541
542 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
543 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
544 it (bug #16298).
545
546 Problem is that for some reason locale fopen's locale.alias with mode "rm".
547
548 -------------------------------------------------------
549 nosferatu root # grep fopen locale.log
550 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
551 nosferatu root #
552 --------------------------------------------------------
553
554 I checked the source of locale, but it have fopen with mode 'r', so
555 not sure where the "rm" mode comes from. Anyhow, changed the check in
556 before_syscall_open_char() to also see mode "rm" as readonly.
557
558 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
559
560 Add glibc-2.3 support.
561
562 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
563
564 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
565 operations releated to preload, as well as only try to modify ld.so.preload
566 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
567 not using ld.so.preload. Fix to not write this instance of sandbox's pid
568 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
569
570 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
571
572 Changed the LD to CC for hppa.
573
574 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
575
576 Killed the previous changes I made.
577
578 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
579
580 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
581
582 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
583
584 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
585
586 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
587
588 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
589 for this fix.
590
591 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
592
593 sandbox_futils defined a dirname() function that was masking the same
594 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
595 '/usr/lib/portage/bi/'). Fixed function to return expected results and
596 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
597 11231.
598
599 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
600
601 Fix a segfault in libsandbox.c if canonicalize() was called with
602 first parameter = NULL.
603
604 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
605
606 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
607 cleanup() for this.
608
609 Change cleanup() in sandbox.c not to exit with fail status if
610 the pidsfile is missing. We really should still display sandbox
611 violations if they occured.
612
613 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
614
615 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
616 the last sandbox running.
617
618 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
619
620 Major cleanups to mainly libsandbox.c again.
621
622 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
623
624 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
625 parties involved should please contact me so that we can fix it.
626
627 Add opendir wrapper to libsandbox.c.
628
629 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
630
631 Do some more cleanups to ecanonicalize(), as it dropped filenames in
632 rare cases (after my symlink cleanups), and caused glibc to bork.
633 These fixes went into canonicalize.c.
634
635 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
636
637 Fix spawn_shell() and main() in sandbox.c to properly return fail
638 status.
639
640 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
641
642 The new canonicalize() function in libsandbox.c also resolved symlinks,
643 which caused on cleaning sandbox errors if the symlink pointed to a
644 file in the live root. Ripped out canonicalize() and realpath() from
645 glibc; removed the symlink stuff, and changed them to ecanonicalize()
646 and erealpath().
647
648 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
649
650 Ripped out all the wrappers, and implemented those of InstallWatch.
651 Losts of cleanups and bugfixes. Implement a execve that forces
652 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
653 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
654 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
655 parts; it now have an install target.
656
657 Reformat the whole thing to look somewhat like the reworked sandbox.c
658 and new sandbox.h and sandbox_futils.c from:
659
660 Brad House <brad@mainstreetsoftworks.com>.
661
662 Additional Copyrights now due to the InstallWatch code:
