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