4
5 01 Dec 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, Makefile.am,
6 localdecls.h, scripts/Makefile.am, scripts/gen_symbol_version_map.awk,
7 scripts/gen_symbol_header.awk, src/Makefile.am, src/symbols.in,
8 src/libsandbox.c, src/getcwd.c, src/sandbox.c, data/sandbox.bashrc:
9
10 Use versioned symbols on supported libc's for functions we wrap, as well as
11 provide all versions of specific functions. Some syntax cleanups.
12
13 Only check SANDBOX_ACTIVE, and not its value. More BASH_ENV fixes.
14
15 Rename configure.in to configure.ac.
16
17 28 Nov 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, sandbox.c,
18 sandbox_fdutils.c:
19
20 Detect if we on 64bit arch automatically.
21
22 Update contact email. Fix quoting.
23
24 Revert 64bit arch test, as we should build the 32bit version without full
25 path checking as well, and add --enable-multilib switch to configure.
26
27 * sandbox-1.2.14 (2005/11/28)
28
29 28 Nov 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
30 sandbox.c, sandbox.h, sandbox.bashrc:
31
32 Check generic getcwd()'s return as well for validity, bug #101728.
33
34 Cleanup environ variables.
35
36 Rather check SANDBOX_ACTIVE if we are already running. Set SANDBOX_ACTIVE
37 to readonly in sandbox.bashrc.
38
39 Make sure we use our bashrc.
40
41 01 Nov 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
42
43 Do not pass mode to true_open and true_open64 if not needed. Should fix a
44 segfault in some cases.
45
46 * sandbox-1.2.13 (2005/09/12)
47
48 12 Sep 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, libsandbox.c:
49
50 Do not handle adding working directory to SANDBOX_WRITE, as portage does it
51 itself.
52
53 Make libsb_fini() do cleanup a bit more complete just in case we get another
54 uClibc 'call preloaded library fini before that of app' issue ... probably
55 will not help much, but we try.
56
57 04 Sep 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
58
59 Also allow symlink() system call to operate on a symlink in a writable path
60 that points to non-writable path, bug #104711.
61
62 * sandbox-1.2.12 (2005/08/05)
63
64 05 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
65 sandbox.h:
66
67 Do not give an access violation if the access() system call do not have
68 write/read access - it does not actually modify, so we only need to return
69 not being able to write/read. Noted by Andres Loeh <kosmikus@gentoo.org>,
70 bug #101433.
71
72 If we are called from the command line, do not care about PORTAGE_TMPDIR,
73 and make the current directory the work directory. Also rename the variable
74 portage_tmp_dir to work_dir.
75
76 Remove the tmp_dir variable - we do not need it.
77
78 Improve error handling for get_sandbox_*_envvar() functions.
79
80 01 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
81
82 Still do normal log if debugging is requested.
83
84 Add support for SANDBOX_VERBOSE (enabled by default). Adjust SANDBOX_DEBUG
85 to only enable if equal to "1" or "yes".
86
87 Add /dev/tts to write permit, bug #42809.
88
89 27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
90 sandbox_futils.c:
91
92 Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that
93 in libsandbox .. bug #100309.
94
95 22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h:
96
97 Print all logging to stderr, bug #90343, comment #15, by Zac Medico.
98
99 * sandbox-1.2.11 (2005/07/14)
100
101 14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
102 Fix getcwd, bug #98419.
103
104 08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c,
105 libsandbox.c:
106 - Try to cleanup and make error handling/printing consistent.
107 - Remove old logs if present and conflicting with current.
108 - Fix compile error with previous change, and return rather then exit().
109
110 07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
111 sandbox.h, sandbox_futils.c:
112 - Fix possible segfault in env init code.
113 - Major cleanup of sandbox_futils.c. Removed most of the functions as we now
114 write to /var/log/sandbox/, so in theory do not need all that.
115 - Redo the interface of the get_* functions so that we do not leak memory.
116 - Remove sandbox_dir and co - we are not using it anymore.
117 - Remove unused includes and variables.
118 - Only declare functions in sandbox_futils.c that are used in libsandbox.c when
119 OUTSIDE_LIBSANDBOX is not defined.
120 - Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log
121 printing's last line not honouring NOCOLOR.
122
123 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
124 libsandbox.c:
125 - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
126 write to it.
127 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
128 - Add check_prefixes() with major cleanup on check_access().
129 - Cleanup init_env_entries() and check_prefixes().
130
131 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
132 sandbox_futils.c, libsandbox.c:
133 Remove unused 'pids file' code.
134
135 * sandbox-1.2.10 (2005/07/03)
136
137 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
138 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
139
140 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
141 General cleanups:
142 - Remove fooling around with exit codes - we error out on presence of a log
143 anyhow.
144 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
145 appropriate there.
146
147 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
148 Cleanup the fail_nametoolong stuff a bit more.
149
150 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
151 Remove hopefully the last ld.so.preload bits we do not use anymore.
152
153 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
154 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
155 in check_syscall(). Should speed things up a bit (at least for the getcwd()
156 and long path name test it goes down to under a second, and not 10+ seconds
157 like before). Also warn if we skip checking due to the canonicalized path
158 being too long.
159
160 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
161 More comment/readability cleanups.
162
163 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
164 sandbox_futils.c, libsandbox.c:
165 Some strncpy/strncat and other cleanups.
166
167 * sandbox-1.2.9 (2005/06/09)
168
169 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
170 Move symlink hack down a bit to try and minimize on the amount of lstat()
171 calls we do.
172
173 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
174 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
175
176 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
177 Add wrapper for access() function, bug #85413.
178
179 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
180 Use generic getcwd() implementation from uclibc - should be more portable
181 and looks a bit cleaner.
182
183 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
184 Make sure our true_* pointers are initialized to NULL, and that we check for
185 all references that they are valid.
186
187 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
188 Be default we will fail if the path name we try to canonicalize is too long.
189 This however could cause issues with some things (bug #94630 and #21766), so
190 if fail_nametoolong == 0, canonicalize() will return a null length string and
191 do not fail.
192
193 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
194 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
195 make sure we re-export the new TMPDIR environment variable.
196
197 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
198 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
199 by Marcus D. Hanwell <cryos@gentoo.org>.
200
201 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
202 Add /dev/console to write list, bug #38588.
203
204 * sandbox-1.2.8 (2005/05/13)
205
206 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
207 sandbox.h, sandbox_futils.c:
208 General cleanups.
209
210 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
211 sandbox.h:
212 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
213
214 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
215 sandbox.h, sandbox_futils.c:
216 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
217 to use TMPDIR if present in environment.
218
219 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
220 Remove sandbox_log_file from main() as its no longer used.
221
222 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
223 sandbox_futils.c:
224 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
225 if already exported when sandbox started). Fix get_sandbox_log() and new
226 get_sandbox_debug_log() to not use already exported environment variables if
227 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
228 SB_PATH_MAX fixes.
229
230 * sandbox-1.2.7 (2005/05/12)
231
232 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
233 sandbox_futils.c:
234 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
235
236 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
237 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
238 with '(null)' in it if we did not call sandbox with absolute path.
239
240 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
241 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
242 for the child.
243
244 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
245 Remove global preload_adaptable as it is no longer used.
246
247 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
248 Rewrite environment stuff to only be set when execve'ing the child process
249 to try and avoid issues like bug #91541 that causes sandbox to crash if
250 we set LD_PRELOAD sandbox side already.
251
252 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
253 Move print_sandbox_log() up to make things neater.
254
255 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
256 Remove load_preload_libs(), as its not used anymore.
257
258 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
259 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
260
261 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
262 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
263
264 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
265 Remove ld.so.preload crap - we are not going to use it again.
266
267 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
268 Fix typo in code that checks if we got valid group information, causing a
269 segmentation fault, bug #91637.
270
271 * sandbox-1.2.6 (2005/05/10)
272
273 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
274 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
275 for some odd reason, bug #91541.
276
277 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
278 Fix typo (sizeof -> strlen).
279
280 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
281 rewrote the sbcontext caching code so it accounts for env changes since lib
282 initialization.
283
284 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
285 We create libctest.c via configure, so no need to keep it around. Do some
286 cleanup related to libctest.c and libctest during configure.
287
288 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
289 Add rename support of symlinks pointing to protected files/directories.
290
291 * sandbox-1.2.5 (2005/05/04)
292
293 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
294 sandbox.bashrc:
295 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
296 already set, init of the env vars fails for some reason, so do this later on,
297 and do not warn (bug #91431).
298
299 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
300 sandbox.bashrc:
301 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
302
303 * sandbox-1.2.4 (2005/05/03)
304
305 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
306 Do not init the env entries with each call, as it creates too many calls to
307 lstat, etc. Should speedup things a bit, bug #91040.
308
309 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
310 Add /dev/pty to default write list. Noticed by Morfic.
311
312 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
313 sandbox.h:
314 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
315 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
316
317 * sandbox-1.2.3 (2005/04/29)
318
319 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
320 Do not check for (*&#$(* CXX or F77.
321
322 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
323 Do not append '/' to pathname in filter_path() if it already ends with it.
324
325 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
326 With az's help, clean up autotools to work with cross-compiling.
327
328 * sandbox-1.2.2 (2005/04/28)
329
330 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
331 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
332 have issues; bug #90592.
333
334 * sandbox-1.2.1 (2005/04/23)
335
336 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
337 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
338 Make sure all functions used in libsandbox.c is declared static. Define
339 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
340 linking with its object. Hopefully this will fix bug #90153.
341
342 * sandbox-1.2 (2005/04/23)
343
344 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
345 Allow lchown a symlink in write-allowed path pointing to write-denied
346 target.
347
348 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
349 Also show resolved symlink names in the log.
350
351 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
352 Seems -nostdlib was the problem with the constructor/destructor - remove it
353 from Makefile.am, and change the constructor/destructor names again.
354
355 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
356 Also rename the _init() and _fini() declarations.
357
358 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
359 Fixup the constructor/destructor function names again (they should be _init()
360 and _fini() it seems, and not being called caused sandbox_lib_path to be
361 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
362 Add both the path in given SANDBOX_x variable, as well as its symlink
363 resolved path in init_env_entries(). Modify filter_path() to be able to
364 resolve paths without resolving symlinks, as well as to be able to resolve
365 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
366 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
367 for bug #31019 cause access violations if we try to remove a symlink that is
368 not in protected path, but points to a protected path. Fix a memory leak in
369 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
370 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
371 (pid_string was uninitialized). General syntax cleanups.
372
373 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
374 infamous "pids file is not a regular file" w/out newline bug.
375
376 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
377 Correct libc_version path detection, since it was screwing up if libdir !=
378 "/lib/".
379
380 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
381 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
382
383 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
384 Fix symbols.in not added to dist.
385
386 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
387 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
388 White space fixes.
389
390 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
391 configure.in, getcwd.c, libsandbox.c, symbols.in:
392 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
393 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
394 for glibc and other libc's that use this. Update libsandbox.c to use these
395 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
396 process unset it.
397
398 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
399 killed off _init and _fini in favor of
400 void __attribute__ ((constructor)) init_func and
401 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
402
403 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
404 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
405 having the hick-ups.
406
407 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
408 Makefile.am: Fixed compilation.
409
410 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
411 Gutted the bugger so it stops checking for a c++ and fortran compiler.
412 Do *not* regenerate aclocal.m4 for making a release until a better
413 solution is created.
414
415 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
416 Removal of more hardcoded paths.
417
418 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
419 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.

421 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
422 Sandbox is now autotooled, create-localdecls needs to be killed and the code
423 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
424 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
425 To get to a point of testing, automake && autoconf; created requisite files w/
426 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
427 /lib and /usr/lib/portage/bin.
428
429 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
430 closing out bug #70225, potential overflow of the sandbox_pids_file var.
431
432 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
433 (think it was at least) allows intermixing of code and data segments. bug #70351
434 should be fixed by this.
435
436 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
437 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
438
439 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
440 Seth Robertson that tracked down all adjuct flags for read operations that
441 do not invoke a write operation.
442
443 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
444 Another fix from jstubbs regarding a free() on a stack variable for the
445 environment -- tracking now prevents extraneous free()'s segfault.
446
447 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
448 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
449 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
450 Also remove the errno = ESUCCESS settings as documentation points out that
451 a library isn't allowed to do that.
452
453 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
454 file_security_check() function to check random potential exploits on files
455 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
456 the 'system-crippling' exploits (bug 21923) and catches a few other
457 potential problems.
458
459 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
460 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
461
462 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
463 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
464 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
465
466 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
467 Fix permissions and group of pids file and logs. Permissions should be 0664
468 and group should be 'portage'. Bug #34260.
469
470 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
471 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
472 to the real execve (in our execve wrapper). Seems that on some arches (sparc
473 among others) do not allow us to tamper with the readonly copy passed to
474 execve, so pass our own copy of the environment. Bug #42290.
475
476 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
477 Changed tail to head and added a notice about duration of glibc check.
478
479 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
480 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
481 as there isn't a guarentee that it is dynamic.
482
483 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
484 If 'file' passed to before_syscall(const char *func, const char *file) is
485 invalid, we should set errno to ENOENT, and not EINVAL. This should
486 close bug #32238.
487
488 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
489 Fix a bug that occurs mainly on 64bit arch, where the file passed to
490 the functions we wrap, is invalid, and then cause canonicalize to pass
491 garbage to before_syscall(), thanks to great detective work from
492 Andrea Luzzardi <al@sig11.org> (bug #29846).
493
494 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
495 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
496
497 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
498 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
499 only checked the destination patch, and not the source, so we could move
500 a protected file to a unprotected directory, and then delete/modify it.
501 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
502
503 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
504 Added python2.3 to the predict section/variable.
505
506 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
507 sandbox.h, sandbox_futils.c :
508 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
509 it is not set, it will revert to its old value.
510
511 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
512 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
513 rather than failing with a violation, bug #29748.
514
515 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
516 Fix canonicalize() to ignore calls with path = "".
517
518 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
519 sandbox_futils.c, canonicalize.c :
520 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
521 call handled strings larger than PATH_MAX (bug #21766). It however does not
522 work the same on 2.4 kernels.
523
524 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
525 do not need the system call. We use the default getcwd() function via a
526 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
527 means the current directory was removed, OR that the the system call for
528 getcwd failed (curious is that it do not fail and return NULL or set
529 errno, but rather just truncate the retured directory - usually from the
530 start), and if so, we use the generic getcwd() function (__egetcwd). Note
531 that we do not use the generic version all the time, as it calls lstat()
532 a great number of times, and performance degrade much.
533
534 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
535 libsandbox.c :
536 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
537
538 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
539 create-localdecls :
540 When checking path names of files accessed, we need to canonicalize it, else
541 it may be a symlink in a 'write allowed' directory pointing to a file in a
542 directory we should not have write access to.
543
544 With something like coreutils-5.0, we have two problems:
545 1) One of the tests checks if getcwd() can return a path longer than
546 PATH_MAX. This test then tries to create a dir which even while
547 created local (mkdir("conftest2")), it ends up being resolved with
548 a name that is much larger than PATH_MAX. The problem now is that
549 canonicalize() have undefined behaviour when the path was too long
550 (returned wrongly truncated paths, etc), and pass the wrong path to
551 before_syscall() (causing the bogus sandbox violations).
552 2) The ecanonicalize() function we used, along with the canonicalize()
553 function did not support longer than PATH_MAX. This is partly a
554 cause for 1), but the error checking (rather lack of it) of calls
555 to erealpath() in canonicalize() was the prime reason for 1).
556
557 As we do not use this canonicalized name to call the function, we resolve this
558 by fixing canonicalize() to do better error checking, and ecanonicalize() as
559 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
560 While they will resolve paths properly now, and can check if a write/read is
561 allowed, the functions called from the sandboxed environment will still work
562 as expected.
563
564 This should resolve bug #21766.
565
566 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
567 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
568 it (bug #16298).
569
570 Problem is that for some reason locale fopen's locale.alias with mode "rm".
571
572 -------------------------------------------------------
573 nosferatu root # grep fopen locale.log
574 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
575 nosferatu root #
576 --------------------------------------------------------
577
578 I checked the source of locale, but it have fopen with mode 'r', so
579 not sure where the "rm" mode comes from. Anyhow, changed the check in
580 before_syscall_open_char() to also see mode "rm" as readonly.
581
582 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
583
584 Add glibc-2.3 support.
585
586 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
587
588 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
589 operations releated to preload, as well as only try to modify ld.so.preload
590 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
591 not using ld.so.preload. Fix to not write this instance of sandbox's pid
592 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
593
594 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
595
596 Changed the LD to CC for hppa.
597
598 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
599
600 Killed the previous changes I made.
601
602 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
603
604 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
605
606 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
607
608 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
609
610 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
611
612 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
613 for this fix.
614
615 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
616
617 sandbox_futils defined a dirname() function that was masking the same
618 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
619 '/usr/lib/portage/bi/'). Fixed function to return expected results and
620 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
621 11231.
622
623 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
624
625 Fix a segfault in libsandbox.c if canonicalize() was called with
626 first parameter = NULL.
627
628 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
629
630 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
631 cleanup() for this.
632
633 Change cleanup() in sandbox.c not to exit with fail status if
634 the pidsfile is missing. We really should still display sandbox
635 violations if they occured.
636
637 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
638
639 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
640 the last sandbox running.
641
642 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
643
644 Major cleanups to mainly libsandbox.c again.
645
646 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
647
648 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
649 parties involved should please contact me so that we can fix it.
650
651 Add opendir wrapper to libsandbox.c.
652
653 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
654
655 Do some more cleanups to ecanonicalize(), as it dropped filenames in
656 rare cases (after my symlink cleanups), and caused glibc to bork.
657 These fixes went into canonicalize.c.
658
659 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
660
661 Fix spawn_shell() and main() in sandbox.c to properly return fail
662 status.
663
664 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
665
666 The new canonicalize() function in libsandbox.c also resolved symlinks,
667 which caused on cleaning sandbox errors if the symlink pointed to a
668 file in the live root. Ripped out canonicalize() and realpath() from
669 glibc; removed the symlink stuff, and changed them to ecanonicalize()
670 and erealpath().
671
672 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
673
674 Ripped out all the wrappers, and implemented those of InstallWatch.
675 Losts of cleanups and bugfixes. Implement a execve that forces
676 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
677 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
678 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
679 parts; it now have an install target.
680
681 Reformat the whole thing to look somewhat like the reworked sandbox.c
682 and new sandbox.h and sandbox_futils.c from:
683
684 Brad House <brad@mainstreetsoftworks.com>.
685
686 Additional Copyrights now due to the InstallWatch code:
