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

399 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
400 libsandbox.c :
401 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
402
403 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
404 create-localdecls :
405 When checking path names of files accessed, we need to canonicalize it, else
406 it may be a symlink in a 'write allowed' directory pointing to a file in a
407 directory we should not have write access to.
408
409 With something like coreutils-5.0, we have two problems:
410 1) One of the tests checks if getcwd() can return a path longer than
411 PATH_MAX. This test then tries to create a dir which even while
412 created local (mkdir("conftest2")), it ends up being resolved with
413 a name that is much larger than PATH_MAX. The problem now is that
414 canonicalize() have undefined behaviour when the path was too long
415 (returned wrongly truncated paths, etc), and pass the wrong path to
416 before_syscall() (causing the bogus sandbox violations).
417 2) The ecanonicalize() function we used, along with the canonicalize()
418 function did not support longer than PATH_MAX. This is partly a
419 cause for 1), but the error checking (rather lack of it) of calls
420 to erealpath() in canonicalize() was the prime reason for 1).
421
422 As we do not use this canonicalized name to call the function, we resolve this
423 by fixing canonicalize() to do better error checking, and ecanonicalize() as
424 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
425 While they will resolve paths properly now, and can check if a write/read is
426 allowed, the functions called from the sandboxed environment will still work
427 as expected.
428
429 This should resolve bug #21766.
430
431 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
432 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
433 it (bug #16298).
434
435 Problem is that for some reason locale fopen's locale.alias with mode "rm".
436
437 -------------------------------------------------------
438 nosferatu root # grep fopen locale.log
439 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
440 nosferatu root #
441 --------------------------------------------------------
442
443 I checked the source of locale, but it have fopen with mode 'r', so
444 not sure where the "rm" mode comes from. Anyhow, changed the check in
445 before_syscall_open_char() to also see mode "rm" as readonly.
446
447 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
448
449 Add glibc-2.3 support.
450
451 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
452
453 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
454 operations releated to preload, as well as only try to modify ld.so.preload
455 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
456 not using ld.so.preload. Fix to not write this instance of sandbox's pid
457 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
458
459 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
460
461 Changed the LD to CC for hppa.
462
463 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
464
465 Killed the previous changes I made.
466
467 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
468
469 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
470
471 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
472
473 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
474
475 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
476
477 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
478 for this fix.
479
480 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
481
482 sandbox_futils defined a dirname() function that was masking the same
483 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
484 '/usr/lib/portage/bi/'). Fixed function to return expected results and
485 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
486 11231.
487
488 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
489
490 Fix a segfault in libsandbox.c if canonicalize() was called with
491 first parameter = NULL.
492
493 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
494
495 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
496 cleanup() for this.
497
498 Change cleanup() in sandbox.c not to exit with fail status if
499 the pidsfile is missing. We really should still display sandbox
500 violations if they occured.
501
502 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
503
504 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
505 the last sandbox running.
506
507 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
508
509 Major cleanups to mainly libsandbox.c again.
510
511 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
512
513 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
514 parties involved should please contact me so that we can fix it.
515
516 Add opendir wrapper to libsandbox.c.
517
518 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
519
520 Do some more cleanups to ecanonicalize(), as it dropped filenames in
521 rare cases (after my symlink cleanups), and caused glibc to bork.
522 These fixes went into canonicalize.c.
523
524 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
525
526 Fix spawn_shell() and main() in sandbox.c to properly return fail
527 status.
528
529 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
530
531 The new canonicalize() function in libsandbox.c also resolved symlinks,
532 which caused on cleaning sandbox errors if the symlink pointed to a
533 file in the live root. Ripped out canonicalize() and realpath() from
534 glibc; removed the symlink stuff, and changed them to ecanonicalize()
535 and erealpath().
536
537 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
538
539 Ripped out all the wrappers, and implemented those of InstallWatch.
540 Losts of cleanups and bugfixes. Implement a execve that forces
541 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
542 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
543 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
544 parts; it now have an install target.
545
546 Reformat the whole thing to look somewhat like the reworked sandbox.c
547 and new sandbox.h and sandbox_futils.c from:
548
549 Brad House <brad@mainstreetsoftworks.com>.
