3 # $Header$
4
5 * sandbox-1.2.14 (2005/11/28)
6
7 28 Nov 2005 Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
8 sandbox.c, sandbox.h, sandbox.bashrc:
9
10 Check generic getcwd()'s return as well for validity, bug #101728.
11
12 Cleanup environ variables.
13
14 Rather check SANDBOX_ACTIVE if we are already running. Set SANDBOX_ACTIVE
15 to readonly in sandbox.bashrc.
16
17 Make sure we use our bashrc.
18
19 01 Nov 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
20
21 Do not pass mode to true_open and true_open64 if not needed. Should fix a
22 segfault in some cases.
23
24 * sandbox-1.2.13 (2005/09/12)
25
26 12 Sep 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, libsandbox.c:
27
28 Do not handle adding working directory to SANDBOX_WRITE, as portage does it
29 itself.
30
31 Make libsb_fini() do cleanup a bit more complete just in case we get another
32 uClibc 'call preloaded library fini before that of app' issue ... probably
33 will not help much, but we try.
34
35 04 Sep 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
36
37 Also allow symlink() system call to operate on a symlink in a writable path
38 that points to non-writable path, bug #104711.
39
40 * sandbox-1.2.12 (2005/08/05)
41
42 05 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
43 sandbox.h:
44
45 Do not give an access violation if the access() system call do not have
46 write/read access - it does not actually modify, so we only need to return
47 not being able to write/read. Noted by Andres Loeh <kosmikus@gentoo.org>,
48 bug #101433.
49
50 If we are called from the command line, do not care about PORTAGE_TMPDIR,
51 and make the current directory the work directory. Also rename the variable
52 portage_tmp_dir to work_dir.
53
54 Remove the tmp_dir variable - we do not need it.
55
56 Improve error handling for get_sandbox_*_envvar() functions.
57
58 01 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
59
60 Still do normal log if debugging is requested.
61
62 Add support for SANDBOX_VERBOSE (enabled by default). Adjust SANDBOX_DEBUG
63 to only enable if equal to "1" or "yes".
64
65 Add /dev/tts to write permit, bug #42809.
66
67 27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
68 sandbox_futils.c:
69
70 Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that
71 in libsandbox .. bug #100309.
72
73 22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h:
74
75 Print all logging to stderr, bug #90343, comment #15, by Zac Medico.
76
77 * sandbox-1.2.11 (2005/07/14)
78
79 14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
80 Fix getcwd, bug #98419.
81
82 08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c,
83 libsandbox.c:
84 - Try to cleanup and make error handling/printing consistent.
85 - Remove old logs if present and conflicting with current.
86 - Fix compile error with previous change, and return rather then exit().
87
88 07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
89 sandbox.h, sandbox_futils.c:
90 - Fix possible segfault in env init code.
91 - Major cleanup of sandbox_futils.c. Removed most of the functions as we now
92 write to /var/log/sandbox/, so in theory do not need all that.
93 - Redo the interface of the get_* functions so that we do not leak memory.
94 - Remove sandbox_dir and co - we are not using it anymore.
95 - Remove unused includes and variables.
96 - Only declare functions in sandbox_futils.c that are used in libsandbox.c when
97 OUTSIDE_LIBSANDBOX is not defined.
98 - Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log
99 printing's last line not honouring NOCOLOR.
100
101 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
102 libsandbox.c:
103 - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
104 write to it.
105 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
106 - Add check_prefixes() with major cleanup on check_access().
107 - Cleanup init_env_entries() and check_prefixes().
108
109 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
110 sandbox_futils.c, libsandbox.c:
111 Remove unused 'pids file' code.
112
113 * sandbox-1.2.10 (2005/07/03)
114
115 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
116 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
117
118 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
119 General cleanups:
120 - Remove fooling around with exit codes - we error out on presence of a log
121 anyhow.
122 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
123 appropriate there.
124
125 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
126 Cleanup the fail_nametoolong stuff a bit more.
127
128 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
129 Remove hopefully the last ld.so.preload bits we do not use anymore.
130
131 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
132 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
133 in check_syscall(). Should speed things up a bit (at least for the getcwd()
134 and long path name test it goes down to under a second, and not 10+ seconds
135 like before). Also warn if we skip checking due to the canonicalized path
136 being too long.
137
138 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
139 More comment/readability cleanups.
140
141 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
142 sandbox_futils.c, libsandbox.c:
143 Some strncpy/strncat and other cleanups.
144
145 * sandbox-1.2.9 (2005/06/09)
146
147 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
148 Move symlink hack down a bit to try and minimize on the amount of lstat()
149 calls we do.
150
151 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
152 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
153
154 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
155 Add wrapper for access() function, bug #85413.
156
157 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
158 Use generic getcwd() implementation from uclibc - should be more portable
159 and looks a bit cleaner.
160
161 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
162 Make sure our true_* pointers are initialized to NULL, and that we check for
163 all references that they are valid.
164
165 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
166 Be default we will fail if the path name we try to canonicalize is too long.
167 This however could cause issues with some things (bug #94630 and #21766), so
168 if fail_nametoolong == 0, canonicalize() will return a null length string and
169 do not fail.
170
171 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
172 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
173 make sure we re-export the new TMPDIR environment variable.
174
175 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
176 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
177 by Marcus D. Hanwell <cryos@gentoo.org>.
178
179 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
180 Add /dev/console to write list, bug #38588.
181
182 * sandbox-1.2.8 (2005/05/13)
183
184 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
185 sandbox.h, sandbox_futils.c:
186 General cleanups.
187
188 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
189 sandbox.h:
190 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
191
192 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
193 sandbox.h, sandbox_futils.c:
194 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
195 to use TMPDIR if present in environment.
196
197 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
198 Remove sandbox_log_file from main() as its no longer used.
199
200 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
201 sandbox_futils.c:
202 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
203 if already exported when sandbox started). Fix get_sandbox_log() and new
204 get_sandbox_debug_log() to not use already exported environment variables if
205 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
206 SB_PATH_MAX fixes.
207
208 * sandbox-1.2.7 (2005/05/12)
209
210 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
211 sandbox_futils.c:
212 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
213
214 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
215 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
216 with '(null)' in it if we did not call sandbox with absolute path.
217
218 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
219 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
220 for the child.
221
222 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
223 Remove global preload_adaptable as it is no longer used.
224
225 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
226 Rewrite environment stuff to only be set when execve'ing the child process
227 to try and avoid issues like bug #91541 that causes sandbox to crash if
228 we set LD_PRELOAD sandbox side already.
229
230 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
231 Move print_sandbox_log() up to make things neater.
232
233 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
234 Remove load_preload_libs(), as its not used anymore.
235
236 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
237 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
238
239 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
240 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
241
242 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
243 Remove ld.so.preload crap - we are not going to use it again.
244
245 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
246 Fix typo in code that checks if we got valid group information, causing a
247 segmentation fault, bug #91637.
248
249 * sandbox-1.2.6 (2005/05/10)
250
251 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
252 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
253 for some odd reason, bug #91541.
254
255 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
256 Fix typo (sizeof -> strlen).
257
258 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
259 rewrote the sbcontext caching code so it accounts for env changes since lib
260 initialization.
261
262 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
263 We create libctest.c via configure, so no need to keep it around. Do some
264 cleanup related to libctest.c and libctest during configure.
265
266 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
267 Add rename support of symlinks pointing to protected files/directories.
268
269 * sandbox-1.2.5 (2005/05/04)
270
271 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
272 sandbox.bashrc:
273 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
274 already set, init of the env vars fails for some reason, so do this later on,
275 and do not warn (bug #91431).
276
277 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
278 sandbox.bashrc:
279 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
280
281 * sandbox-1.2.4 (2005/05/03)
282
283 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
284 Do not init the env entries with each call, as it creates too many calls to
285 lstat, etc. Should speedup things a bit, bug #91040.
286
287 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
288 Add /dev/pty to default write list. Noticed by Morfic.
289
290 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
291 sandbox.h:
292 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
293 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
294
295 * sandbox-1.2.3 (2005/04/29)
296
297 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
298 Do not check for (*&#$(* CXX or F77.
299
300 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
301 Do not append '/' to pathname in filter_path() if it already ends with it.
302
303 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
304 With az's help, clean up autotools to work with cross-compiling.
305
306 * sandbox-1.2.2 (2005/04/28)
307
308 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
309 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
310 have issues; bug #90592.
311
312 * sandbox-1.2.1 (2005/04/23)
313
314 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
315 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
316 Make sure all functions used in libsandbox.c is declared static. Define
317 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
318 linking with its object. Hopefully this will fix bug #90153.
319
320 * sandbox-1.2 (2005/04/23)
321
322 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
323 Allow lchown a symlink in write-allowed path pointing to write-denied
324 target.
325
326 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
327 Also show resolved symlink names in the log.
328
329 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
330 Seems -nostdlib was the problem with the constructor/destructor - remove it
331 from Makefile.am, and change the constructor/destructor names again.
332
333 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
334 Also rename the _init() and _fini() declarations.
335
336 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
337 Fixup the constructor/destructor function names again (they should be _init()
338 and _fini() it seems, and not being called caused sandbox_lib_path to be
339 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
340 Add both the path in given SANDBOX_x variable, as well as its symlink
341 resolved path in init_env_entries(). Modify filter_path() to be able to
342 resolve paths without resolving symlinks, as well as to be able to resolve
343 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
344 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
345 for bug #31019 cause access violations if we try to remove a symlink that is
346 not in protected path, but points to a protected path. Fix a memory leak in
347 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
348 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
349 (pid_string was uninitialized). General syntax cleanups.
350
351 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
352 infamous "pids file is not a regular file" w/out newline bug.
353
354 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
355 Correct libc_version path detection, since it was screwing up if libdir !=
356 "/lib/".
357
358 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
359 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
360
361 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
362 Fix symbols.in not added to dist.
363
364 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
365 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
366 White space fixes.
367
368 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
369 configure.in, getcwd.c, libsandbox.c, symbols.in:
370 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
371 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
372 for glibc and other libc's that use this. Update libsandbox.c to use these
373 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
374 process unset it.
375
376 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
377 killed off _init and _fini in favor of
378 void __attribute__ ((constructor)) init_func and
379 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
380
381 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
382 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
383 having the hick-ups.
384
385 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
386 Makefile.am: Fixed compilation.
387
388 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
389 Gutted the bugger so it stops checking for a c++ and fortran compiler.
390 Do *not* regenerate aclocal.m4 for making a release until a better
391 solution is created.
392
393 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
394 Removal of more hardcoded paths.
395
396 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
397 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
398
399 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
400 Sandbox is now autotooled, create-localdecls needs to be killed and the code
401 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
402 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
403 To get to a point of testing, automake && autoconf; created requisite files w/
404 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
405 /lib and /usr/lib/portage/bin.
406
407 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
408 closing out bug #70225, potential overflow of the sandbox_pids_file var.
409
410 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
411 (think it was at least) allows intermixing of code and data segments. bug #70351
412 should be fixed by this.

414 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
415 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
416
417 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
418 Seth Robertson that tracked down all adjuct flags for read operations that
419 do not invoke a write operation.
420
421 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
422 Another fix from jstubbs regarding a free() on a stack variable for the
423 environment -- tracking now prevents extraneous free()'s segfault.
424
425 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
426 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
427 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
428 Also remove the errno = ESUCCESS settings as documentation points out that
429 a library isn't allowed to do that.
430
431 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
432 file_security_check() function to check random potential exploits on files
433 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
434 the 'system-crippling' exploits (bug 21923) and catches a few other
435 potential problems.
436
437 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
438 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
439
440 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
441 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
442 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
443
444 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
445 Fix permissions and group of pids file and logs. Permissions should be 0664
446 and group should be 'portage'. Bug #34260.
447
448 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
449 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
450 to the real execve (in our execve wrapper). Seems that on some arches (sparc
451 among others) do not allow us to tamper with the readonly copy passed to
452 execve, so pass our own copy of the environment. Bug #42290.
453
454 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
455 Changed tail to head and added a notice about duration of glibc check.
456
457 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
458 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
459 as there isn't a guarentee that it is dynamic.
460
461 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
462 If 'file' passed to before_syscall(const char *func, const char *file) is
463 invalid, we should set errno to ENOENT, and not EINVAL. This should
464 close bug #32238.
465
466 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
467 Fix a bug that occurs mainly on 64bit arch, where the file passed to
468 the functions we wrap, is invalid, and then cause canonicalize to pass
469 garbage to before_syscall(), thanks to great detective work from
470 Andrea Luzzardi <al@sig11.org> (bug #29846).
471
472 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
473 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
474
475 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
476 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
477 only checked the destination patch, and not the source, so we could move
478 a protected file to a unprotected directory, and then delete/modify it.
479 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
480
481 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
482 Added python2.3 to the predict section/variable.
483
484 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
485 sandbox.h, sandbox_futils.c :
486 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
487 it is not set, it will revert to its old value.
488
489 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
490 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
491 rather than failing with a violation, bug #29748.
492
493 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
494 Fix canonicalize() to ignore calls with path = "".
495
496 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
497 sandbox_futils.c, canonicalize.c :
498 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
499 call handled strings larger than PATH_MAX (bug #21766). It however does not
500 work the same on 2.4 kernels.
501
502 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
503 do not need the system call. We use the default getcwd() function via a
504 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
505 means the current directory was removed, OR that the the system call for
506 getcwd failed (curious is that it do not fail and return NULL or set
507 errno, but rather just truncate the retured directory - usually from the
508 start), and if so, we use the generic getcwd() function (__egetcwd). Note
509 that we do not use the generic version all the time, as it calls lstat()
510 a great number of times, and performance degrade much.
511
512 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
513 libsandbox.c :
514 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
515
516 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
517 create-localdecls :
518 When checking path names of files accessed, we need to canonicalize it, else
519 it may be a symlink in a 'write allowed' directory pointing to a file in a
520 directory we should not have write access to.
521
522 With something like coreutils-5.0, we have two problems:
523 1) One of the tests checks if getcwd() can return a path longer than
524 PATH_MAX. This test then tries to create a dir which even while
525 created local (mkdir("conftest2")), it ends up being resolved with
526 a name that is much larger than PATH_MAX. The problem now is that
527 canonicalize() have undefined behaviour when the path was too long
528 (returned wrongly truncated paths, etc), and pass the wrong path to
529 before_syscall() (causing the bogus sandbox violations).
530 2) The ecanonicalize() function we used, along with the canonicalize()
531 function did not support longer than PATH_MAX. This is partly a
532 cause for 1), but the error checking (rather lack of it) of calls
533 to erealpath() in canonicalize() was the prime reason for 1).
534
535 As we do not use this canonicalized name to call the function, we resolve this
536 by fixing canonicalize() to do better error checking, and ecanonicalize() as
537 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
538 While they will resolve paths properly now, and can check if a write/read is
539 allowed, the functions called from the sandboxed environment will still work
540 as expected.
541
542 This should resolve bug #21766.
543
544 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
545 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
546 it (bug #16298).
547
548 Problem is that for some reason locale fopen's locale.alias with mode "rm".
549
550 -------------------------------------------------------
551 nosferatu root # grep fopen locale.log
552 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
553 nosferatu root #
554 --------------------------------------------------------
555
556 I checked the source of locale, but it have fopen with mode 'r', so
557 not sure where the "rm" mode comes from. Anyhow, changed the check in
558 before_syscall_open_char() to also see mode "rm" as readonly.
559
560 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
561
562 Add glibc-2.3 support.
563
564 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
565
566 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
567 operations releated to preload, as well as only try to modify ld.so.preload
568 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
569 not using ld.so.preload. Fix to not write this instance of sandbox's pid
570 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
571
572 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
573
574 Changed the LD to CC for hppa.
575
576 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
577
578 Killed the previous changes I made.
579
580 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
581
582 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
583
584 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
585
586 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
587
588 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
589
590 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
591 for this fix.
592
593 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
594
595 sandbox_futils defined a dirname() function that was masking the same
596 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
597 '/usr/lib/portage/bi/'). Fixed function to return expected results and
598 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
599 11231.
600
601 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
602
603 Fix a segfault in libsandbox.c if canonicalize() was called with
604 first parameter = NULL.
605
606 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
607
608 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
609 cleanup() for this.
610
611 Change cleanup() in sandbox.c not to exit with fail status if
612 the pidsfile is missing. We really should still display sandbox
613 violations if they occured.
614
615 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
616
617 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
618 the last sandbox running.
619
620 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
621
622 Major cleanups to mainly libsandbox.c again.
623
624 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
625
626 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
627 parties involved should please contact me so that we can fix it.
628
629 Add opendir wrapper to libsandbox.c.
630
631 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
632
633 Do some more cleanups to ecanonicalize(), as it dropped filenames in
634 rare cases (after my symlink cleanups), and caused glibc to bork.
635 These fixes went into canonicalize.c.
636
637 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
638
639 Fix spawn_shell() and main() in sandbox.c to properly return fail
640 status.
641
642 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
643
644 The new canonicalize() function in libsandbox.c also resolved symlinks,
645 which caused on cleaning sandbox errors if the symlink pointed to a
646 file in the live root. Ripped out canonicalize() and realpath() from
647 glibc; removed the symlink stuff, and changed them to ecanonicalize()
648 and erealpath().
649
650 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
651
652 Ripped out all the wrappers, and implemented those of InstallWatch.
653 Losts of cleanups and bugfixes. Implement a execve that forces
654 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
655 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
656 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
657 parts; it now have an install target.
658
659 Reformat the whole thing to look somewhat like the reworked sandbox.c
660 and new sandbox.h and sandbox_futils.c from:
661
662 Brad House <brad@mainstreetsoftworks.com>.
663
664 Additional Copyrights now due to the InstallWatch code:
