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