4
5 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6 Cleanup the fail_nametoolong stuff a bit more.
7
8 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
9 Remove hopefully the last ld.so.preload bits we do not use anymore.
10
11 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
12 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
13 in check_syscall(). Should speed things up a bit (at least for the getcwd()
14 and long path name test it goes down to under a second, and not 10+ seconds
15 like before). Also warn if we skip checking due to the canonicalized path
16 being too long.
17
18 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
19 More comment/readability cleanups.
20
21 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
22 sandbox_futils.c, libsandbox.c:
23 Some strncpy/strncat and other cleanups.
24
25 * sandbox-1.2.9 (2005/06/09)
26
27 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
28 Move symlink hack down a bit to try and minimize on the amount of lstat()
29 calls we do.
30
31 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
32 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
33
34 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
35 Add wrapper for access() function, bug #85413.
36
37 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
38 Use generic getcwd() implementation from uclibc - should be more portable
39 and looks a bit cleaner.
40
41 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
42 Make sure our true_* pointers are initialized to NULL, and that we check for
43 all references that they are valid.
44
45 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
46 Be default we will fail if the path name we try to canonicalize is too long.
47 This however could cause issues with some things (bug #94630 and #21766), so
48 if fail_nametoolong == 0, canonicalize() will return a null length string and
49 do not fail.
50
51 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
52 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
53 make sure we re-export the new TMPDIR environment variable.
54
55 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
56 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
57 by Marcus D. Hanwell <cryos@gentoo.org>.
58
59 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
60 Add /dev/console to write list, bug #38588.
61
62 * sandbox-1.2.8 (2005/05/13)
63
64 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
65 sandbox.h, sandbox_futils.c:
66 General cleanups.
67
68 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
69 sandbox.h:
70 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
71
72 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
73 sandbox.h, sandbox_futils.c:
74 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
75 to use TMPDIR if present in environment.
76
77 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
78 Remove sandbox_log_file from main() as its no longer used.
79
80 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
81 sandbox_futils.c:
82 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
83 if already exported when sandbox started). Fix get_sandbox_log() and new
84 get_sandbox_debug_log() to not use already exported environment variables if
85 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
86 SB_PATH_MAX fixes.
87
88 * sandbox-1.2.7 (2005/05/12)
89
90 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
91 sandbox_futils.c:
92 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
93
94 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
95 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
96 with '(null)' in it if we did not call sandbox with absolute path.
97
98 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
99 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
100 for the child.
101
102 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
103 Remove global preload_adaptable as it is no longer used.
104
105 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
106 Rewrite environment stuff to only be set when execve'ing the child process
107 to try and avoid issues like bug #91541 that causes sandbox to crash if
108 we set LD_PRELOAD sandbox side already.
109
110 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
111 Move print_sandbox_log() up to make things neater.
112
113 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
114 Remove load_preload_libs(), as its not used anymore.
115
116 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
117 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
118
119 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
120 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
121
122 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
123 Remove ld.so.preload crap - we are not going to use it again.
124
125 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
126 Fix typo in code that checks if we got valid group information, causing a
127 segmentation fault, bug #91637.
128
129 * sandbox-1.2.6 (2005/05/10)
130
131 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
132 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
133 for some odd reason, bug #91541.
134
135 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
136 Fix typo (sizeof -> strlen).
137
138 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
139 rewrote the sbcontext caching code so it accounts for env changes since lib
140 initialization.
141
142 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
143 We create libctest.c via configure, so no need to keep it around. Do some
144 cleanup related to libctest.c and libctest during configure.
145
146 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
147 Add rename support of symlinks pointing to protected files/directories.
148
149 * sandbox-1.2.5 (2005/05/04)
150
151 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
152 sandbox.bashrc:
153 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
154 already set, init of the env vars fails for some reason, so do this later on,
155 and do not warn (bug #91431).
156
157 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
158 sandbox.bashrc:
159 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
160
161 * sandbox-1.2.4 (2005/05/03)
162
163 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
164 Do not init the env entries with each call, as it creates too many calls to
165 lstat, etc. Should speedup things a bit, bug #91040.
166
167 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
168 Add /dev/pty to default write list. Noticed by Morfic.
169
170 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
171 sandbox.h:
172 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
173 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
174
175 * sandbox-1.2.3 (2005/04/29)
176
177 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
178 Do not check for (*&#$(* CXX or F77.
179
180 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
181 Do not append '/' to pathname in filter_path() if it already ends with it.
182
183 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
184 With az's help, clean up autotools to work with cross-compiling.
185
186 * sandbox-1.2.2 (2005/04/28)
187
188 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
189 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
190 have issues; bug #90592.
191
192 * sandbox-1.2.1 (2005/04/23)
193
194 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
195 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
196 Make sure all functions used in libsandbox.c is declared static. Define
197 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
198 linking with its object. Hopefully this will fix bug #90153.
199
200 * sandbox-1.2 (2005/04/23)
201
202 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
203 Allow lchown a symlink in write-allowed path pointing to write-denied
204 target.
205
206 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
207 Also show resolved symlink names in the log.
208
209 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
210 Seems -nostdlib was the problem with the constructor/destructor - remove it
211 from Makefile.am, and change the constructor/destructor names again.
212
213 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
214 Also rename the _init() and _fini() declarations.
215
216 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
217 Fixup the constructor/destructor function names again (they should be _init()
218 and _fini() it seems, and not being called caused sandbox_lib_path to be
219 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
220 Add both the path in given SANDBOX_x variable, as well as its symlink
221 resolved path in init_env_entries(). Modify filter_path() to be able to
222 resolve paths without resolving symlinks, as well as to be able to resolve
223 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
224 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
225 for bug #31019 cause access violations if we try to remove a symlink that is
226 not in protected path, but points to a protected path. Fix a memory leak in
227 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
228 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
229 (pid_string was uninitialized). General syntax cleanups.
230
231 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
232 infamous "pids file is not a regular file" w/out newline bug.
233
234 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
235 Correct libc_version path detection, since it was screwing up if libdir !=
236 "/lib/".
237
238 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
239 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
240
241 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
242 Fix symbols.in not added to dist.
243
244 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
245 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
246 White space fixes.
247
248 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
249 configure.in, getcwd.c, libsandbox.c, symbols.in:
250 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
251 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
252 for glibc and other libc's that use this. Update libsandbox.c to use these
253 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
254 process unset it.
255
256 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
257 killed off _init and _fini in favor of
258 void __attribute__ ((constructor)) init_func and
259 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
260
261 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
262 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
263 having the hick-ups.
264
265 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
266 Makefile.am: Fixed compilation.
267
268 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
269 Gutted the bugger so it stops checking for a c++ and fortran compiler.
270 Do *not* regenerate aclocal.m4 for making a release until a better
271 solution is created.
272
273 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
274 Removal of more hardcoded paths.
275
276 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
277 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
278
279 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
280 Sandbox is now autotooled, create-localdecls needs to be killed and the code
281 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
282 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
283 To get to a point of testing, automake && autoconf; created requisite files w/
284 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
285 /lib and /usr/lib/portage/bin.
286
287 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
288 closing out bug #70225, potential overflow of the sandbox_pids_file var.
289
290 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
291 (think it was at least) allows intermixing of code and data segments. bug #70351
292 should be fixed by this.
293
294 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
295 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
296
297 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
298 Seth Robertson that tracked down all adjuct flags for read operations that
299 do not invoke a write operation.
300
301 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
302 Another fix from jstubbs regarding a free() on a stack variable for the
303 environment -- tracking now prevents extraneous free()'s segfault.
304
305 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
306 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
307 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
308 Also remove the errno = ESUCCESS settings as documentation points out that
309 a library isn't allowed to do that.
310
311 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
312 file_security_check() function to check random potential exploits on files
313 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
314 the 'system-crippling' exploits (bug 21923) and catches a few other
315 potential problems.
316
317 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
318 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
319
320 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
321 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
322 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
323
324 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
325 Fix permissions and group of pids file and logs. Permissions should be 0664
326 and group should be 'portage'. Bug #34260.
327
328 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
329 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
330 to the real execve (in our execve wrapper). Seems that on some arches (sparc
331 among others) do not allow us to tamper with the readonly copy passed to
332 execve, so pass our own copy of the environment. Bug #42290.
333
334 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
335 Changed tail to head and added a notice about duration of glibc check.
336
337 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
338 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
339 as there isn't a guarentee that it is dynamic.
340
341 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
342 If 'file' passed to before_syscall(const char *func, const char *file) is
343 invalid, we should set errno to ENOENT, and not EINVAL. This should
344 close bug #32238.
345
346 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
347 Fix a bug that occurs mainly on 64bit arch, where the file passed to
348 the functions we wrap, is invalid, and then cause canonicalize to pass
349 garbage to before_syscall(), thanks to great detective work from
350 Andrea Luzzardi <al@sig11.org> (bug #29846).
351
352 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
353 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
354
355 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
356 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
357 only checked the destination patch, and not the source, so we could move
358 a protected file to a unprotected directory, and then delete/modify it.
359 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
360
361 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
362 Added python2.3 to the predict section/variable.
363
364 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
365 sandbox.h, sandbox_futils.c :
366 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
367 it is not set, it will revert to its old value.
368
369 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
370 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
371 rather than failing with a violation, bug #29748.
372
373 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
374 Fix canonicalize() to ignore calls with path = "".
375
376 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
377 sandbox_futils.c, canonicalize.c :
378 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
379 call handled strings larger than PATH_MAX (bug #21766). It however does not
380 work the same on 2.4 kernels.
381
382 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
383 do not need the system call. We use the default getcwd() function via a
384 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
385 means the current directory was removed, OR that the the system call for
386 getcwd failed (curious is that it do not fail and return NULL or set
387 errno, but rather just truncate the retured directory - usually from the
388 start), and if so, we use the generic getcwd() function (__egetcwd). Note
389 that we do not use the generic version all the time, as it calls lstat()
390 a great number of times, and performance degrade much.
391
392 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
393 libsandbox.c :
394 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
395
396 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
397 create-localdecls :
398 When checking path names of files accessed, we need to canonicalize it, else
399 it may be a symlink in a 'write allowed' directory pointing to a file in a
400 directory we should not have write access to.
401
402 With something like coreutils-5.0, we have two problems:
403 1) One of the tests checks if getcwd() can return a path longer than
404 PATH_MAX. This test then tries to create a dir which even while
405 created local (mkdir("conftest2")), it ends up being resolved with
406 a name that is much larger than PATH_MAX. The problem now is that
407 canonicalize() have undefined behaviour when the path was too long
408 (returned wrongly truncated paths, etc), and pass the wrong path to
409 before_syscall() (causing the bogus sandbox violations).
410 2) The ecanonicalize() function we used, along with the canonicalize()
411 function did not support longer than PATH_MAX. This is partly a
412 cause for 1), but the error checking (rather lack of it) of calls
413 to erealpath() in canonicalize() was the prime reason for 1).
414
415 As we do not use this canonicalized name to call the function, we resolve this
416 by fixing canonicalize() to do better error checking, and ecanonicalize() as
417 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
418 While they will resolve paths properly now, and can check if a write/read is
419 allowed, the functions called from the sandboxed environment will still work
420 as expected.
421
422 This should resolve bug #21766.
423
424 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
425 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
426 it (bug #16298).
427
428 Problem is that for some reason locale fopen's locale.alias with mode "rm".
429
430 -------------------------------------------------------
431 nosferatu root # grep fopen locale.log
432 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
433 nosferatu root #
434 --------------------------------------------------------
435
436 I checked the source of locale, but it have fopen with mode 'r', so
437 not sure where the "rm" mode comes from. Anyhow, changed the check in
438 before_syscall_open_char() to also see mode "rm" as readonly.
439
440 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
441
442 Add glibc-2.3 support.
443
444 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
445
446 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
447 operations releated to preload, as well as only try to modify ld.so.preload
448 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
449 not using ld.so.preload. Fix to not write this instance of sandbox's pid
450 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
451
452 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
453
454 Changed the LD to CC for hppa.
455
456 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
457
458 Killed the previous changes I made.
459
460 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
461
462 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
463
464 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
465
466 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
467
468 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
469
470 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
471 for this fix.
472
473 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
474
475 sandbox_futils defined a dirname() function that was masking the same
476 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
477 '/usr/lib/portage/bi/'). Fixed function to return expected results and
478 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
479 11231.
480
481 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
482
483 Fix a segfault in libsandbox.c if canonicalize() was called with
484 first parameter = NULL.
485
486 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
487
488 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
489 cleanup() for this.
490
491 Change cleanup() in sandbox.c not to exit with fail status if
492 the pidsfile is missing. We really should still display sandbox
493 violations if they occured.
494
495 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
496
497 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
498 the last sandbox running.
499
500 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
501
502 Major cleanups to mainly libsandbox.c again.
503
504 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
505
506 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
507 parties involved should please contact me so that we can fix it.
508
509 Add opendir wrapper to libsandbox.c.
510
511 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
512
513 Do some more cleanups to ecanonicalize(), as it dropped filenames in
514 rare cases (after my symlink cleanups), and caused glibc to bork.
515 These fixes went into canonicalize.c.
516
517 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
518
519 Fix spawn_shell() and main() in sandbox.c to properly return fail
520 status.
521
522 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
523
524 The new canonicalize() function in libsandbox.c also resolved symlinks,
525 which caused on cleaning sandbox errors if the symlink pointed to a
526 file in the live root. Ripped out canonicalize() and realpath() from
527 glibc; removed the symlink stuff, and changed them to ecanonicalize()
528 and erealpath().
529
530 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
531
532 Ripped out all the wrappers, and implemented those of InstallWatch.
533 Losts of cleanups and bugfixes. Implement a execve that forces
534 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
535 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
536 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
537 parts; it now have an install target.
538
539 Reformat the whole thing to look somewhat like the reworked sandbox.c
540 and new sandbox.h and sandbox_futils.c from:
541
542 Brad House <brad@mainstreetsoftworks.com>.
543
544 Additional Copyrights now due to the InstallWatch code:
