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

413 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
414 libsandbox.c :
415 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
416
417 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
418 create-localdecls :
419 When checking path names of files accessed, we need to canonicalize it, else
420 it may be a symlink in a 'write allowed' directory pointing to a file in a
421 directory we should not have write access to.
422
423 With something like coreutils-5.0, we have two problems:
424 1) One of the tests checks if getcwd() can return a path longer than
425 PATH_MAX. This test then tries to create a dir which even while
426 created local (mkdir("conftest2")), it ends up being resolved with
427 a name that is much larger than PATH_MAX. The problem now is that
428 canonicalize() have undefined behaviour when the path was too long
429 (returned wrongly truncated paths, etc), and pass the wrong path to
430 before_syscall() (causing the bogus sandbox violations).
431 2) The ecanonicalize() function we used, along with the canonicalize()
432 function did not support longer than PATH_MAX. This is partly a
433 cause for 1), but the error checking (rather lack of it) of calls
434 to erealpath() in canonicalize() was the prime reason for 1).
435
436 As we do not use this canonicalized name to call the function, we resolve this
437 by fixing canonicalize() to do better error checking, and ecanonicalize() as
438 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
439 While they will resolve paths properly now, and can check if a write/read is
440 allowed, the functions called from the sandboxed environment will still work
441 as expected.
442
443 This should resolve bug #21766.
444
445 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
446 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
447 it (bug #16298).
448
449 Problem is that for some reason locale fopen's locale.alias with mode "rm".
450
451 -------------------------------------------------------
452 nosferatu root # grep fopen locale.log
453 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
454 nosferatu root #
455 --------------------------------------------------------
456
457 I checked the source of locale, but it have fopen with mode 'r', so
458 not sure where the "rm" mode comes from. Anyhow, changed the check in
459 before_syscall_open_char() to also see mode "rm" as readonly.
460
461 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
462
463 Add glibc-2.3 support.
464
465 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
466
467 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
468 operations releated to preload, as well as only try to modify ld.so.preload
469 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
470 not using ld.so.preload. Fix to not write this instance of sandbox's pid
471 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
472
473 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
474
475 Changed the LD to CC for hppa.
476
477 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
478
479 Killed the previous changes I made.
480
481 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
482
483 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
484
485 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
486
487 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
488
489 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
490
491 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
492 for this fix.
493
494 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
495
496 sandbox_futils defined a dirname() function that was masking the same
497 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
498 '/usr/lib/portage/bi/'). Fixed function to return expected results and
499 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
500 11231.
501
502 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
503
504 Fix a segfault in libsandbox.c if canonicalize() was called with
505 first parameter = NULL.
506
507 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
508
509 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
510 cleanup() for this.
511
512 Change cleanup() in sandbox.c not to exit with fail status if
513 the pidsfile is missing. We really should still display sandbox
514 violations if they occured.
515
516 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
517
518 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
519 the last sandbox running.
520
521 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
522
523 Major cleanups to mainly libsandbox.c again.
524
525 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
526
527 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
528 parties involved should please contact me so that we can fix it.
529
530 Add opendir wrapper to libsandbox.c.
531
532 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
533
534 Do some more cleanups to ecanonicalize(), as it dropped filenames in
535 rare cases (after my symlink cleanups), and caused glibc to bork.
536 These fixes went into canonicalize.c.
537
538 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
539
540 Fix spawn_shell() and main() in sandbox.c to properly return fail
541 status.
542
543 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
544
545 The new canonicalize() function in libsandbox.c also resolved symlinks,
546 which caused on cleaning sandbox errors if the symlink pointed to a
547 file in the live root. Ripped out canonicalize() and realpath() from
548 glibc; removed the symlink stuff, and changed them to ecanonicalize()
549 and erealpath().
550
551 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
552
553 Ripped out all the wrappers, and implemented those of InstallWatch.
554 Losts of cleanups and bugfixes. Implement a execve that forces
555 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
556 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
557 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
558 parts; it now have an install target.
559
560 Reformat the whole thing to look somewhat like the reworked sandbox.c
561 and new sandbox.h and sandbox_futils.c from:
562
563 Brad House <brad@mainstreetsoftworks.com>.
