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