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