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

350    
351     I checked the source of locale, but it have fopen with mode 'r', so
352     not sure where the "rm" mode comes from. Anyhow, changed the check in
353     before_syscall_open_char() to also see mode "rm" as readonly.
354    
355     23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
356    
357     Add glibc-2.3 support.
358    
359     22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
360    
361     Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
362     operations releated to preload, as well as only try to modify ld.so.preload
363     if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
364     not using ld.so.preload. Fix to not write this instance of sandbox's pid
365     to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
366    
367     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
368    
369     Changed the LD to CC for hppa.
370    
371     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
372    
373     Killed the previous changes I made.
374    
375     17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
376    
377     Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
378    
379     09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
380    
381     Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
382    
383     16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
384    
385     Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
386     for this fix.
387    
388     4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
389    
390     sandbox_futils defined a dirname() function that was masking the same
391     function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
392     '/usr/lib/portage/bi/'). Fixed function to return expected results and
393     renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
394     11231.
395    
396     4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
397    
398     Fix a segfault in libsandbox.c if canonicalize() was called with
399     first parameter = NULL.
400    
401     1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
402    
403     Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
404     cleanup() for this.
405    
406     Change cleanup() in sandbox.c not to exit with fail status if
407     the pidsfile is missing. We really should still display sandbox
408     violations if they occured.
409    
410     31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
411    
412     Update cleanup() in sandbox.c to remove the PIDSFILE if this is
413     the last sandbox running.
414    
415     25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
416    
417     Major cleanups to mainly libsandbox.c again.
418    
419     22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
420    
421     Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
422     parties involved should please contact me so that we can fix it.
423    
424     Add opendir wrapper to libsandbox.c.
425    
426     21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
427    
428     Do some more cleanups to ecanonicalize(), as it dropped filenames in
429     rare cases (after my symlink cleanups), and caused glibc to bork.
430     These fixes went into canonicalize.c.
431    
432     20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
433    
434     Fix spawn_shell() and main() in sandbox.c to properly return fail
435     status.
436    
437     19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
438    
439     The new canonicalize() function in libsandbox.c also resolved symlinks,
440     which caused on cleaning sandbox errors if the symlink pointed to a
441     file in the live root. Ripped out canonicalize() and realpath() from
442     glibc; removed the symlink stuff, and changed them to ecanonicalize()
443     and erealpath().
444    
445     18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
446    
447     Ripped out all the wrappers, and implemented those of InstallWatch.
448     Losts of cleanups and bugfixes. Implement a execve that forces
449     $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
450     /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
451     sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
452     parts; it now have an install target.
453    
454     Reformat the whole thing to look somewhat like the reworked sandbox.c
455     and new sandbox.h and sandbox_futils.c from:
456    
457     Brad House <brad@mainstreetsoftworks.com>.
458    
459     Additional Copyrights now due to the InstallWatch code:
