4
5 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
6 sandbox_futils.c, libsandbox.c:
7 Remove unused 'pids file' code.
8
9 * sandbox-1.2.10 (2005/07/03)
10
11 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
12 Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
13
14 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
15 General cleanups:
16 - Remove fooling around with exit codes - we error out on presence of a log
17 anyhow.
18 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
19 appropriate there.
20
21 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
22 Cleanup the fail_nametoolong stuff a bit more.
23
24 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
25 Remove hopefully the last ld.so.preload bits we do not use anymore.
26
27 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
28 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
29 in check_syscall(). Should speed things up a bit (at least for the getcwd()
30 and long path name test it goes down to under a second, and not 10+ seconds
31 like before). Also warn if we skip checking due to the canonicalized path
32 being too long.
33
34 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
35 More comment/readability cleanups.
36
37 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
38 sandbox_futils.c, libsandbox.c:
39 Some strncpy/strncat and other cleanups.
40
41 * sandbox-1.2.9 (2005/06/09)
42
43 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
44 Move symlink hack down a bit to try and minimize on the amount of lstat()
45 calls we do.
46
47 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
48 Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
49
50 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
51 Add wrapper for access() function, bug #85413.
52
53 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
54 Use generic getcwd() implementation from uclibc - should be more portable
55 and looks a bit cleaner.
56
57 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
58 Make sure our true_* pointers are initialized to NULL, and that we check for
59 all references that they are valid.
60
61 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
62 Be default we will fail if the path name we try to canonicalize is too long.
63 This however could cause issues with some things (bug #94630 and #21766), so
64 if fail_nametoolong == 0, canonicalize() will return a null length string and
65 do not fail.
66
67 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
68 Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
69 make sure we re-export the new TMPDIR environment variable.
70
71 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
72 Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
73 by Marcus D. Hanwell <cryos@gentoo.org>.
74
75 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
76 Add /dev/console to write list, bug #38588.
77
78 * sandbox-1.2.8 (2005/05/13)
79
80 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
81 sandbox.h, sandbox_futils.c:
82 General cleanups.
83
84 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
85 sandbox.h:
86 Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
87
88 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
89 sandbox.h, sandbox_futils.c:
90 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
91 to use TMPDIR if present in environment.
92
93 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
94 Remove sandbox_log_file from main() as its no longer used.
95
96 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
97 sandbox_futils.c:
98 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
99 if already exported when sandbox started). Fix get_sandbox_log() and new
100 get_sandbox_debug_log() to not use already exported environment variables if
101 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
102 SB_PATH_MAX fixes.
103
104 * sandbox-1.2.7 (2005/05/12)
105
106 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
107 sandbox_futils.c:
108 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
109
110 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
111 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
112 with '(null)' in it if we did not call sandbox with absolute path.
113
114 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
115 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
116 for the child.
117
118 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
119 Remove global preload_adaptable as it is no longer used.
120
121 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
122 Rewrite environment stuff to only be set when execve'ing the child process
123 to try and avoid issues like bug #91541 that causes sandbox to crash if
124 we set LD_PRELOAD sandbox side already.
125
126 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
127 Move print_sandbox_log() up to make things neater.
128
129 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
130 Remove load_preload_libs(), as its not used anymore.
131
132 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
133 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
134
135 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
136 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
137
138 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
139 Remove ld.so.preload crap - we are not going to use it again.
140
141 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
142 Fix typo in code that checks if we got valid group information, causing a
143 segmentation fault, bug #91637.
144
145 * sandbox-1.2.6 (2005/05/10)
146
147 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
148 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
149 for some odd reason, bug #91541.
150
151 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
152 Fix typo (sizeof -> strlen).
153
154 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
155 rewrote the sbcontext caching code so it accounts for env changes since lib
156 initialization.
157
158 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
159 We create libctest.c via configure, so no need to keep it around. Do some
160 cleanup related to libctest.c and libctest during configure.
161
162 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
163 Add rename support of symlinks pointing to protected files/directories.
164
165 * sandbox-1.2.5 (2005/05/04)
166
167 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
168 sandbox.bashrc:
169 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
170 already set, init of the env vars fails for some reason, so do this later on,
171 and do not warn (bug #91431).
172
173 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
174 sandbox.bashrc:
175 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
176
177 * sandbox-1.2.4 (2005/05/03)
178
179 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
180 Do not init the env entries with each call, as it creates too many calls to
181 lstat, etc. Should speedup things a bit, bug #91040.
182
183 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
184 Add /dev/pty to default write list. Noticed by Morfic.
185
186 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
187 sandbox.h:
188 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
189 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
190
191 * sandbox-1.2.3 (2005/04/29)
192
193 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
194 Do not check for (*&#$(* CXX or F77.
195
196 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
197 Do not append '/' to pathname in filter_path() if it already ends with it.
198
199 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
200 With az's help, clean up autotools to work with cross-compiling.
201
202 * sandbox-1.2.2 (2005/04/28)
203
204 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
205 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
206 have issues; bug #90592.
207
208 * sandbox-1.2.1 (2005/04/23)
209
210 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
211 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
212 Make sure all functions used in libsandbox.c is declared static. Define
213 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
214 linking with its object. Hopefully this will fix bug #90153.
215
216 * sandbox-1.2 (2005/04/23)
217
218 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
219 Allow lchown a symlink in write-allowed path pointing to write-denied
220 target.
221
222 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
223 Also show resolved symlink names in the log.
224
225 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
226 Seems -nostdlib was the problem with the constructor/destructor - remove it
227 from Makefile.am, and change the constructor/destructor names again.
228
229 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
230 Also rename the _init() and _fini() declarations.
231
232 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
233 Fixup the constructor/destructor function names again (they should be _init()
234 and _fini() it seems, and not being called caused sandbox_lib_path to be
235 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
236 Add both the path in given SANDBOX_x variable, as well as its symlink
237 resolved path in init_env_entries(). Modify filter_path() to be able to
238 resolve paths without resolving symlinks, as well as to be able to resolve
239 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
240 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
241 for bug #31019 cause access violations if we try to remove a symlink that is
242 not in protected path, but points to a protected path. Fix a memory leak in
243 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
244 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
245 (pid_string was uninitialized). General syntax cleanups.
246
247 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
248 infamous "pids file is not a regular file" w/out newline bug.
249
250 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
251 Correct libc_version path detection, since it was screwing up if libdir !=
252 "/lib/".
253
254 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
255 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
256
257 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
258 Fix symbols.in not added to dist.
259
260 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
261 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
262 White space fixes.
263
264 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
265 configure.in, getcwd.c, libsandbox.c, symbols.in:
266 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
267 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
268 for glibc and other libc's that use this. Update libsandbox.c to use these
269 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
270 process unset it.
271
272 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
273 killed off _init and _fini in favor of
274 void __attribute__ ((constructor)) init_func and
275 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
276
277 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
278 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
279 having the hick-ups.
280
281 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
282 Makefile.am: Fixed compilation.
283
284 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
285 Gutted the bugger so it stops checking for a c++ and fortran compiler.
286 Do *not* regenerate aclocal.m4 for making a release until a better
287 solution is created.
288
289 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
290 Removal of more hardcoded paths.
291
292 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
293 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
294
295 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
296 Sandbox is now autotooled, create-localdecls needs to be killed and the code
297 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
298 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
299 To get to a point of testing, automake && autoconf; created requisite files w/
300 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
301 /lib and /usr/lib/portage/bin.
302
303 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
304 closing out bug #70225, potential overflow of the sandbox_pids_file var.
305
306 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
307 (think it was at least) allows intermixing of code and data segments. bug #70351
308 should be fixed by this.
309
310 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
311 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
312
313 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
314 Seth Robertson that tracked down all adjuct flags for read operations that
315 do not invoke a write operation.
316
317 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
318 Another fix from jstubbs regarding a free() on a stack variable for the
319 environment -- tracking now prevents extraneous free()'s segfault.
320
321 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
322 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
323 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
324 Also remove the errno = ESUCCESS settings as documentation points out that
325 a library isn't allowed to do that.
326
327 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
328 file_security_check() function to check random potential exploits on files
329 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
330 the 'system-crippling' exploits (bug 21923) and catches a few other
331 potential problems.
332
333 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
334 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
335
336 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
337 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
338 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
339
340 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
341 Fix permissions and group of pids file and logs. Permissions should be 0664
342 and group should be 'portage'. Bug #34260.
343
344 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
345 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
346 to the real execve (in our execve wrapper). Seems that on some arches (sparc
347 among others) do not allow us to tamper with the readonly copy passed to
348 execve, so pass our own copy of the environment. Bug #42290.
349
350 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
351 Changed tail to head and added a notice about duration of glibc check.
352
353 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
354 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
355 as there isn't a guarentee that it is dynamic.
356
357 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
358 If 'file' passed to before_syscall(const char *func, const char *file) is
359 invalid, we should set errno to ENOENT, and not EINVAL. This should
360 close bug #32238.
361
362 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
363 Fix a bug that occurs mainly on 64bit arch, where the file passed to
364 the functions we wrap, is invalid, and then cause canonicalize to pass
365 garbage to before_syscall(), thanks to great detective work from
366 Andrea Luzzardi <al@sig11.org> (bug #29846).
367
368 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
369 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
370
371 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
372 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
373 only checked the destination patch, and not the source, so we could move
374 a protected file to a unprotected directory, and then delete/modify it.
375 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
376
377 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
378 Added python2.3 to the predict section/variable.
379
380 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
381 sandbox.h, sandbox_futils.c :
382 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
383 it is not set, it will revert to its old value.
384
385 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
386 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
387 rather than failing with a violation, bug #29748.
388
389 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
390 Fix canonicalize() to ignore calls with path = "".
391
392 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
393 sandbox_futils.c, canonicalize.c :
394 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
395 call handled strings larger than PATH_MAX (bug #21766). It however does not
396 work the same on 2.4 kernels.
397
398 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
399 do not need the system call. We use the default getcwd() function via a
400 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
401 means the current directory was removed, OR that the the system call for
402 getcwd failed (curious is that it do not fail and return NULL or set
403 errno, but rather just truncate the retured directory - usually from the
404 start), and if so, we use the generic getcwd() function (__egetcwd). Note
405 that we do not use the generic version all the time, as it calls lstat()
406 a great number of times, and performance degrade much.

410 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.

412 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
413 create-localdecls :
414 When checking path names of files accessed, we need to canonicalize it, else
415 it may be a symlink in a 'write allowed' directory pointing to a file in a
416 directory we should not have write access to.
417
418 With something like coreutils-5.0, we have two problems:
419 1) One of the tests checks if getcwd() can return a path longer than
420 PATH_MAX. This test then tries to create a dir which even while
421 created local (mkdir("conftest2")), it ends up being resolved with
422 a name that is much larger than PATH_MAX. The problem now is that
423 canonicalize() have undefined behaviour when the path was too long
424 (returned wrongly truncated paths, etc), and pass the wrong path to
425 before_syscall() (causing the bogus sandbox violations).
426 2) The ecanonicalize() function we used, along with the canonicalize()
427 function did not support longer than PATH_MAX. This is partly a
428 cause for 1), but the error checking (rather lack of it) of calls
429 to erealpath() in canonicalize() was the prime reason for 1).
430
431 As we do not use this canonicalized name to call the function, we resolve this
432 by fixing canonicalize() to do better error checking, and ecanonicalize() as
433 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
434 While they will resolve paths properly now, and can check if a write/read is
435 allowed, the functions called from the sandboxed environment will still work
436 as expected.
437
438 This should resolve bug #21766.
439
440 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
441 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
442 it (bug #16298).
443
444 Problem is that for some reason locale fopen's locale.alias with mode "rm".
445
446 -------------------------------------------------------
447 nosferatu root # grep fopen locale.log
448 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
449 nosferatu root #
450 --------------------------------------------------------
451
452 I checked the source of locale, but it have fopen with mode 'r', so
453 not sure where the "rm" mode comes from. Anyhow, changed the check in
454 before_syscall_open_char() to also see mode "rm" as readonly.
455
456 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
457
458 Add glibc-2.3 support.
459
460 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
461
462 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
463 operations releated to preload, as well as only try to modify ld.so.preload
464 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
465 not using ld.so.preload. Fix to not write this instance of sandbox's pid
466 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
467
468 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
469
470 Changed the LD to CC for hppa.
471
472 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
473
474 Killed the previous changes I made.
475
476 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
477
478 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
479
480 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
481
482 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
483
484 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
485
486 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
487 for this fix.
488
489 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
490
491 sandbox_futils defined a dirname() function that was masking the same
492 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
493 '/usr/lib/portage/bi/'). Fixed function to return expected results and
494 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
495 11231.
496
497 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
498
499 Fix a segfault in libsandbox.c if canonicalize() was called with
500 first parameter = NULL.
501
502 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
503
504 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
505 cleanup() for this.
506
507 Change cleanup() in sandbox.c not to exit with fail status if
508 the pidsfile is missing. We really should still display sandbox
509 violations if they occured.
510
511 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
512
513 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
514 the last sandbox running.
515
516 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
517
518 Major cleanups to mainly libsandbox.c again.
519
520 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
521
522 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
523 parties involved should please contact me so that we can fix it.
524
525 Add opendir wrapper to libsandbox.c.
526
527 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
528
529 Do some more cleanups to ecanonicalize(), as it dropped filenames in
530 rare cases (after my symlink cleanups), and caused glibc to bork.
531 These fixes went into canonicalize.c.
532
533 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
534
535 Fix spawn_shell() and main() in sandbox.c to properly return fail
536 status.
537
538 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
539
540 The new canonicalize() function in libsandbox.c also resolved symlinks,
541 which caused on cleaning sandbox errors if the symlink pointed to a
542 file in the live root. Ripped out canonicalize() and realpath() from
543 glibc; removed the symlink stuff, and changed them to ecanonicalize()
544 and erealpath().
545
546 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
547
548 Ripped out all the wrappers, and implemented those of InstallWatch.
549 Losts of cleanups and bugfixes. Implement a execve that forces
550 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
551 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
552 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
553 parts; it now have an install target.
554
555 Reformat the whole thing to look somewhat like the reworked sandbox.c
556 and new sandbox.h and sandbox_futils.c from:
557
558 Brad House <brad@mainstreetsoftworks.com>.
