4
5 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
6 libsandbox.c:
7 - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
8 write to it.
9 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
10 - Add check_prefixes() with major cleanup on check_access().
11 - Cleanup init_env_entries() and check_prefixes().
12
13 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
14 sandbox_futils.c, libsandbox.c:
15 Remove unused 'pids file' code.
16
17 * sandbox-1.2.10 (2005/07/03)
18
19 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
20 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
21
22 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
23 General cleanups:
24 - Remove fooling around with exit codes - we error out on presence of a log
25 anyhow.
26 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
27 appropriate there.
28
29 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
30 Cleanup the fail_nametoolong stuff a bit more.
31
32 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
33 Remove hopefully the last ld.so.preload bits we do not use anymore.
34
35 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
36 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
37 in check_syscall(). Should speed things up a bit (at least for the getcwd()
38 and long path name test it goes down to under a second, and not 10+ seconds
39 like before). Also warn if we skip checking due to the canonicalized path
40 being too long.
41
42 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
43 More comment/readability cleanups.
44
45 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
46 sandbox_futils.c, libsandbox.c:
47 Some strncpy/strncat and other cleanups.
48
49 * sandbox-1.2.9 (2005/06/09)
50
51 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
52 Move symlink hack down a bit to try and minimize on the amount of lstat()
53 calls we do.
54
55 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
56 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
57
58 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
59 Add wrapper for access() function, bug #85413.
60
61 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
62 Use generic getcwd() implementation from uclibc - should be more portable
63 and looks a bit cleaner.
64
65 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
66 Make sure our true_* pointers are initialized to NULL, and that we check for
67 all references that they are valid.
68
69 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
70 Be default we will fail if the path name we try to canonicalize is too long.
71 This however could cause issues with some things (bug #94630 and #21766), so
72 if fail_nametoolong == 0, canonicalize() will return a null length string and
73 do not fail.
74
75 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
76 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
77 make sure we re-export the new TMPDIR environment variable.
78
79 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
80 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
81 by Marcus D. Hanwell <cryos@gentoo.org>.
82
83 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
84 Add /dev/console to write list, bug #38588.
85
86 * sandbox-1.2.8 (2005/05/13)
87
88 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
89 sandbox.h, sandbox_futils.c:
90 General cleanups.
91
92 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
93 sandbox.h:
94 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
95
96 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
97 sandbox.h, sandbox_futils.c:
98 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
99 to use TMPDIR if present in environment.
100
101 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
102 Remove sandbox_log_file from main() as its no longer used.
103
104 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
105 sandbox_futils.c:
106 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
107 if already exported when sandbox started). Fix get_sandbox_log() and new
108 get_sandbox_debug_log() to not use already exported environment variables if
109 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
110 SB_PATH_MAX fixes.
111
112 * sandbox-1.2.7 (2005/05/12)
113
114 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
115 sandbox_futils.c:
116 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
117
118 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
119 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
120 with '(null)' in it if we did not call sandbox with absolute path.
121
122 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
123 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
124 for the child.
125
126 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
127 Remove global preload_adaptable as it is no longer used.
128
129 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
130 Rewrite environment stuff to only be set when execve'ing the child process
131 to try and avoid issues like bug #91541 that causes sandbox to crash if
132 we set LD_PRELOAD sandbox side already.
133
134 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
135 Move print_sandbox_log() up to make things neater.
136
137 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
138 Remove load_preload_libs(), as its not used anymore.
139
140 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
141 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
142
143 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
144 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
145
146 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
147 Remove ld.so.preload crap - we are not going to use it again.
148
149 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
150 Fix typo in code that checks if we got valid group information, causing a
151 segmentation fault, bug #91637.
152
153 * sandbox-1.2.6 (2005/05/10)
154
155 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
156 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
157 for some odd reason, bug #91541.
158
159 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
160 Fix typo (sizeof -> strlen).
161
162 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
163 rewrote the sbcontext caching code so it accounts for env changes since lib
164 initialization.
165
166 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
167 We create libctest.c via configure, so no need to keep it around. Do some
168 cleanup related to libctest.c and libctest during configure.
169
170 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
171 Add rename support of symlinks pointing to protected files/directories.
172
173 * sandbox-1.2.5 (2005/05/04)
174
175 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
176 sandbox.bashrc:
177 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
178 already set, init of the env vars fails for some reason, so do this later on,
179 and do not warn (bug #91431).
180
181 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
182 sandbox.bashrc:
183 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
184
185 * sandbox-1.2.4 (2005/05/03)
186
187 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
188 Do not init the env entries with each call, as it creates too many calls to
189 lstat, etc. Should speedup things a bit, bug #91040.
190
191 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
192 Add /dev/pty to default write list. Noticed by Morfic.
193
194 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
195 sandbox.h:
196 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
197 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
198
199 * sandbox-1.2.3 (2005/04/29)
200
201 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
202 Do not check for (*&#$(* CXX or F77.
203
204 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
205 Do not append '/' to pathname in filter_path() if it already ends with it.
206
207 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
208 With az's help, clean up autotools to work with cross-compiling.
209
210 * sandbox-1.2.2 (2005/04/28)
211
212 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
213 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
214 have issues; bug #90592.
215
216 * sandbox-1.2.1 (2005/04/23)
217
218 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
219 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
220 Make sure all functions used in libsandbox.c is declared static. Define
221 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
222 linking with its object. Hopefully this will fix bug #90153.
223
224 * sandbox-1.2 (2005/04/23)
225
226 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
227 Allow lchown a symlink in write-allowed path pointing to write-denied
228 target.
229
230 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
231 Also show resolved symlink names in the log.
232
233 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
234 Seems -nostdlib was the problem with the constructor/destructor - remove it
235 from Makefile.am, and change the constructor/destructor names again.
236
237 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
238 Also rename the _init() and _fini() declarations.
239
240 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
241 Fixup the constructor/destructor function names again (they should be _init()
242 and _fini() it seems, and not being called caused sandbox_lib_path to be
243 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
244 Add both the path in given SANDBOX_x variable, as well as its symlink
245 resolved path in init_env_entries(). Modify filter_path() to be able to
246 resolve paths without resolving symlinks, as well as to be able to resolve
247 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
248 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
249 for bug #31019 cause access violations if we try to remove a symlink that is
250 not in protected path, but points to a protected path. Fix a memory leak in
251 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
252 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
253 (pid_string was uninitialized). General syntax cleanups.
254
255 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
256 infamous "pids file is not a regular file" w/out newline bug.
257
258 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
259 Correct libc_version path detection, since it was screwing up if libdir !=
260 "/lib/".
261
262 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
263 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
264
265 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
266 Fix symbols.in not added to dist.
267
268 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
269 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
270 White space fixes.
271
272 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
273 configure.in, getcwd.c, libsandbox.c, symbols.in:
274 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
275 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
276 for glibc and other libc's that use this. Update libsandbox.c to use these
277 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
278 process unset it.
279
280 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
281 killed off _init and _fini in favor of
282 void __attribute__ ((constructor)) init_func and
283 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
284
285 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
286 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
287 having the hick-ups.
288
289 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
290 Makefile.am: Fixed compilation.
291
292 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
293 Gutted the bugger so it stops checking for a c++ and fortran compiler.
294 Do *not* regenerate aclocal.m4 for making a release until a better
295 solution is created.
296
297 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
298 Removal of more hardcoded paths.
299
300 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
301 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
302
303 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
304 Sandbox is now autotooled, create-localdecls needs to be killed and the code
305 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
306 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
307 To get to a point of testing, automake && autoconf; created requisite files w/
308 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
309 /lib and /usr/lib/portage/bin.
310
311 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
312 closing out bug #70225, potential overflow of the sandbox_pids_file var.
313
314 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
315 (think it was at least) allows intermixing of code and data segments. bug #70351
316 should be fixed by this.
317
318 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
319 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
320
321 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
322 Seth Robertson that tracked down all adjuct flags for read operations that
323 do not invoke a write operation.
324
325 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
326 Another fix from jstubbs regarding a free() on a stack variable for the
327 environment -- tracking now prevents extraneous free()'s segfault.
328
329 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
330 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
331 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
332 Also remove the errno = ESUCCESS settings as documentation points out that
333 a library isn't allowed to do that.
334
335 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
336 file_security_check() function to check random potential exploits on files
337 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
338 the 'system-crippling' exploits (bug 21923) and catches a few other
339 potential problems.
340
341 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
342 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
343
344 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
345 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
346 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
347
348 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
349 Fix permissions and group of pids file and logs. Permissions should be 0664
350 and group should be 'portage'. Bug #34260.
351
352 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
353 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
354 to the real execve (in our execve wrapper). Seems that on some arches (sparc
355 among others) do not allow us to tamper with the readonly copy passed to
356 execve, so pass our own copy of the environment. Bug #42290.
357
358 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
359 Changed tail to head and added a notice about duration of glibc check.
360
361 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
362 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
363 as there isn't a guarentee that it is dynamic.
364
365 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
366 If 'file' passed to before_syscall(const char *func, const char *file) is
367 invalid, we should set errno to ENOENT, and not EINVAL. This should
368 close bug #32238.
369
370 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
371 Fix a bug that occurs mainly on 64bit arch, where the file passed to
372 the functions we wrap, is invalid, and then cause canonicalize to pass
373 garbage to before_syscall(), thanks to great detective work from
374 Andrea Luzzardi <al@sig11.org> (bug #29846).
375
376 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
377 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
378
379 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
380 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
381 only checked the destination patch, and not the source, so we could move
382 a protected file to a unprotected directory, and then delete/modify it.
383 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
384
385 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
386 Added python2.3 to the predict section/variable.
387
388 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
389 sandbox.h, sandbox_futils.c :
390 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
391 it is not set, it will revert to its old value.
392
393 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
394 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
395 rather than failing with a violation, bug #29748.
396
397 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
398 Fix canonicalize() to ignore calls with path = "".
399
400 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
401 sandbox_futils.c, canonicalize.c :
402 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
403 call handled strings larger than PATH_MAX (bug #21766). It however does not
404 work the same on 2.4 kernels.
405
406 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
407 do not need the system call. We use the default getcwd() function via a
408 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
409 means the current directory was removed, OR that the the system call for
410 getcwd failed (curious is that it do not fail and return NULL or set
411 errno, but rather just truncate the retured directory - usually from the
412 start), and if so, we use the generic getcwd() function (__egetcwd). Note
413 that we do not use the generic version all the time, as it calls lstat()
414 a great number of times, and performance degrade much.

416 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
417 libsandbox.c :
418 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
419
420 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
421 create-localdecls :
422 When checking path names of files accessed, we need to canonicalize it, else
423 it may be a symlink in a 'write allowed' directory pointing to a file in a
424 directory we should not have write access to.
425
426 With something like coreutils-5.0, we have two problems:
427 1) One of the tests checks if getcwd() can return a path longer than
428 PATH_MAX. This test then tries to create a dir which even while
429 created local (mkdir("conftest2")), it ends up being resolved with
430 a name that is much larger than PATH_MAX. The problem now is that
431 canonicalize() have undefined behaviour when the path was too long
432 (returned wrongly truncated paths, etc), and pass the wrong path to
433 before_syscall() (causing the bogus sandbox violations).
434 2) The ecanonicalize() function we used, along with the canonicalize()
435 function did not support longer than PATH_MAX. This is partly a
436 cause for 1), but the error checking (rather lack of it) of calls
437 to erealpath() in canonicalize() was the prime reason for 1).
438
439 As we do not use this canonicalized name to call the function, we resolve this
440 by fixing canonicalize() to do better error checking, and ecanonicalize() as
441 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
442 While they will resolve paths properly now, and can check if a write/read is
443 allowed, the functions called from the sandboxed environment will still work
444 as expected.
445
446 This should resolve bug #21766.
447
448 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
449 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
450 it (bug #16298).
451
452 Problem is that for some reason locale fopen's locale.alias with mode "rm".
453
454 -------------------------------------------------------
455 nosferatu root # grep fopen locale.log
456 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
457 nosferatu root #
458 --------------------------------------------------------
459
460 I checked the source of locale, but it have fopen with mode 'r', so
461 not sure where the "rm" mode comes from. Anyhow, changed the check in
462 before_syscall_open_char() to also see mode "rm" as readonly.
463
464 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
465
466 Add glibc-2.3 support.
467
468 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
469
470 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
471 operations releated to preload, as well as only try to modify ld.so.preload
472 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
473 not using ld.so.preload. Fix to not write this instance of sandbox's pid
474 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
475
476 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
477
478 Changed the LD to CC for hppa.
479
480 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
481
482 Killed the previous changes I made.
483
484 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
485
486 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
487
488 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
489
490 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
491
492 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
493
494 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
495 for this fix.
496
497 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
498
499 sandbox_futils defined a dirname() function that was masking the same
500 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
501 '/usr/lib/portage/bi/'). Fixed function to return expected results and
502 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
503 11231.
504
505 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
506
507 Fix a segfault in libsandbox.c if canonicalize() was called with
508 first parameter = NULL.
509
510 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
511
512 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
513 cleanup() for this.
514
515 Change cleanup() in sandbox.c not to exit with fail status if
516 the pidsfile is missing. We really should still display sandbox
517 violations if they occured.
518
519 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
520
521 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
522 the last sandbox running.
523
524 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
525
526 Major cleanups to mainly libsandbox.c again.
527
528 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
529
530 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
531 parties involved should please contact me so that we can fix it.
532
533 Add opendir wrapper to libsandbox.c.
534
535 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
536
537 Do some more cleanups to ecanonicalize(), as it dropped filenames in
538 rare cases (after my symlink cleanups), and caused glibc to bork.
539 These fixes went into canonicalize.c.
540
541 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
542
543 Fix spawn_shell() and main() in sandbox.c to properly return fail
544 status.
545
546 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
547
548 The new canonicalize() function in libsandbox.c also resolved symlinks,
549 which caused on cleaning sandbox errors if the symlink pointed to a
550 file in the live root. Ripped out canonicalize() and realpath() from
551 glibc; removed the symlink stuff, and changed them to ecanonicalize()
552 and erealpath().
553
554 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
555
556 Ripped out all the wrappers, and implemented those of InstallWatch.
557 Losts of cleanups and bugfixes. Implement a execve that forces
558 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
559 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
560 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
561 parts; it now have an install target.
562
563 Reformat the whole thing to look somewhat like the reworked sandbox.c
564 and new sandbox.h and sandbox_futils.c from:
565
566 Brad House <brad@mainstreetsoftworks.com>.
