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