Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
if already exported when sandbox started).  Fix get_sandbox_log() and new
get_sandbox_debug_log() to not use already exported environment variables if
they have '/' in them.  Use snprintf()'s instead of strncpy()'s.  More
SB_PATH_MAX fixes.

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