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

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

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