5 azarah 106 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6     Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
7     by Marcus D. Hanwell <cryos@gentoo.org>.
8    
9 azarah 105 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
10     Add /dev/console to write list, bug #38588.
11    
12 azarah 102 * sandbox-1.2.8 (2005/05/13)
13    
14 azarah 99 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
15 azarah 101 sandbox.h, sandbox_futils.c:
16     General cleanups.
17    
18     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
19 azarah 100 sandbox.h:
20     Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
21    
22     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
23 azarah 99 sandbox.h, sandbox_futils.c:
24     Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
25     to use TMPDIR if present in environment.
26    
27 azarah 98 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
28     Remove sandbox_log_file from main() as its no longer used.
29    
30 azarah 97 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
31     sandbox_futils.c:
32     Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
33     if already exported when sandbox started). Fix get_sandbox_log() and new
34     get_sandbox_debug_log() to not use already exported environment variables if
35     they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
36     SB_PATH_MAX fixes.
37    
38 azarah 94 * sandbox-1.2.7 (2005/05/12)
39    
40 azarah 93 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
41     sandbox_futils.c:
42     More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
43    
44 azarah 92 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
45     Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
46     with '(null)' in it if we did not call sandbox with absolute path.
47    
48 azarah 89 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
49 azarah 91 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
50     for the child.
51    
52     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
53 azarah 90 Remove global preload_adaptable as it is no longer used.
54    
55     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
56 azarah 89 Rewrite environment stuff to only be set when execve'ing the child process
57     to try and avoid issues like bug #91541 that causes sandbox to crash if
58     we set LD_PRELOAD sandbox side already.
59    
60 azarah 87 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
61 azarah 88 Move print_sandbox_log() up to make things neater.
62    
63     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
64 azarah 87 Remove load_preload_libs(), as its not used anymore.
65    
66 azarah 83 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
67 azarah 86 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
68    
69     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
70 azarah 84 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
71    
72     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
73 azarah 83 Remove ld.so.preload crap - we are not going to use it again.
74    
75 azarah 82 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
76     Fix typo in code that checks if we got valid group information, causing a
77     segmentation fault, bug #91637.
78    
79 azarah 79 * sandbox-1.2.6 (2005/05/10)
80    
81 azarah 78 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
82     Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
83     for some odd reason, bug #91541.
84    
85 azarah 77 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
86     Fix typo (sizeof -> strlen).
87    
88 ferringb 76 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
89     rewrote the sbcontext caching code so it accounts for env changes since lib
90     initialization.
91    
92 azarah 75 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
93     We create libctest.c via configure, so no need to keep it around. Do some
94     cleanup related to libctest.c and libctest during configure.
95    
96 azarah 74 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
97     Add rename support of symlinks pointing to protected files/directories.
98    
99 azarah 72 * sandbox-1.2.5 (2005/05/04)
100    
101 azarah 71 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
102     sandbox.bashrc:
103     Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
104     already set, init of the env vars fails for some reason, so do this later on,
105     and do not warn (bug #91431).
106    
107 azarah 70 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
108     sandbox.bashrc:
109     Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
110    
111 azarah 68 * sandbox-1.2.4 (2005/05/03)
112    
113 azarah 66 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
114     Do not init the env entries with each call, as it creates too many calls to
115 azarah 67 lstat, etc. Should speedup things a bit, bug #91040.
116 azarah 66
117 azarah 65 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
118     Add /dev/pty to default write list. Noticed by Morfic.
119    
120 vapier 62 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
121     sandbox.h:
122     uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
123     exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
124    
125 azarah 59 * sandbox-1.2.3 (2005/04/29)
126    
127 azarah 56 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
128     Do not check for (*&#$(* CXX or F77.
129    
130 azarah 54 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
131     Do not append '/' to pathname in filter_path() if it already ends with it.
132    
133 vapier 53 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
134     With az's help, clean up autotools to work with cross-compiling.
135    
136 azarah 59 * sandbox-1.2.2 (2005/04/28)
137 azarah 48
138 azarah 47 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
139     Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
140     have issues; bug #90592.
141    
142 azarah 59 * sandbox-1.2.1 (2005/04/23)
143 azarah 44
144 azarah 43 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
145     getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
146     Make sure all functions used in libsandbox.c is declared static. Define
147     SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
148     linking with its object. Hopefully this will fix bug #90153.
149    
150 azarah 59 * sandbox-1.2 (2005/04/23)
151 azarah 46
152 azarah 40 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
153     Allow lchown a symlink in write-allowed path pointing to write-denied
154     target.
155    
156 genone 39 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
157     Also show resolved symlink names in the log.
158    
159 azarah 37 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
160     Seems -nostdlib was the problem with the constructor/destructor - remove it
161     from Makefile.am, and change the constructor/destructor names again.
162    
163 azarah 36 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
164     Also rename the _init() and _fini() declarations.
165    
166 azarah 35 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
167     Fixup the constructor/destructor function names again (they should be _init()
168     and _fini() it seems, and not being called caused sandbox_lib_path to be
169     unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
170     Add both the path in given SANDBOX_x variable, as well as its symlink
171     resolved path in init_env_entries(). Modify filter_path() to be able to
172     resolve paths without resolving symlinks, as well as to be able to resolve
173     symlinks. Fix a possible segfault in check_access(). Add symlink resolving
174     to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
175     for bug #31019 cause access violations if we try to remove a symlink that is
176     not in protected path, but points to a protected path. Fix a memory leak in
177     sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
178     (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
179     (pid_string was uninitialized). General syntax cleanups.
180    
181 ferringb 34 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
182     infamous "pids file is not a regular file" w/out newline bug.
183    
184 ferringb 33 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
185     Correct libc_version path detection, since it was screwing up if libdir !=
186     "/lib/".
187    
188     02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
189 azarah 32 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
190    
191 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
192 azarah 31 Fix symbols.in not added to dist.
193    
194 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
195 azarah 30 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
196     White space fixes.
197    
198 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
199 azarah 30 configure.in, getcwd.c, libsandbox.c, symbols.in:
200 azarah 29 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
201     getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
202     for glibc and other libc's that use this. Update libsandbox.c to use these
203     symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
204     process unset it.
205    
206 ferringb 33 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
207 ferringb 28 killed off _init and _fini in favor of
208     void __attribute__ ((constructor)) init_func and
209     void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
210    
211 ferringb 26 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
212     canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
213     having the hick-ups.
214    
215 ferringb 24 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
216     Makefile.am: Fixed compilation.
217    
218 ferringb 18 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
219     Gutted the bugger so it stops checking for a c++ and fortran compiler.
220     Do *not* regenerate aclocal.m4 for making a release until a better
221     solution is created.
222    
223 ferringb 16 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
224     Removal of more hardcoded paths.
225    
226 ferringb 13 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
227     sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
228    
229     19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
230 ferringb 6 Sandbox is now autotooled, create-localdecls needs to be killed and the code
231     shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
232     are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
233     To get to a point of testing, automake && autoconf; created requisite files w/
234     a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
235     /lib and /usr/lib/portage/bin.
236    
237 ferringb 2 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
238     closing out bug #70225, potential overflow of the sandbox_pids_file var.
239    
240     07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
241     (think it was at least) allows intermixing of code and data segments. bug #70351
242     should be fixed by this.
243    
244     03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
245     futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
246    
247     02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
248     Seth Robertson that tracked down all adjuct flags for read operations that
249     do not invoke a write operation.
250    
251     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
252     Another fix from jstubbs regarding a free() on a stack variable for the
253     environment -- tracking now prevents extraneous free()'s segfault.
254    
255     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
256     J. Stubbs tracked down a new bug where mkdir was failing to the patch on
257     the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
258     Also remove the errno = ESUCCESS settings as documentation points out that
259     a library isn't allowed to do that.
260    
261     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
262     file_security_check() function to check random potential exploits on files
263     that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
264     the 'system-crippling' exploits (bug 21923) and catches a few other
265     potential problems.
266    
267     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
268     32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
269    
270     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
271     bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
272     Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
273    
274     29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
275     Fix permissions and group of pids file and logs. Permissions should be 0664
276     and group should be 'portage'. Bug #34260.
277    
278     28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
279     Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
280     to the real execve (in our execve wrapper). Seems that on some arches (sparc
281     among others) do not allow us to tamper with the readonly copy passed to
282     execve, so pass our own copy of the environment. Bug #42290.
283    
284     11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
285     Changed tail to head and added a notice about duration of glibc check.
286    
287     21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
288     Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
289     as there isn't a guarentee that it is dynamic.
290    
291     02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
292     If 'file' passed to before_syscall(const char *func, const char *file) is
293     invalid, we should set errno to ENOENT, and not EINVAL. This should
294     close bug #32238.
295    
296     14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
297     Fix a bug that occurs mainly on 64bit arch, where the file passed to
298     the functions we wrap, is invalid, and then cause canonicalize to pass
299     garbage to before_syscall(), thanks to great detective work from
300     Andrea Luzzardi <al@sig11.org> (bug #29846).
301    
302     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
303     Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
304    
305     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
306     Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
307     only checked the destination patch, and not the source, so we could move
308     a protected file to a unprotected directory, and then delete/modify it.
309     Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
310    
311     12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
312     Added python2.3 to the predict section/variable.
313    
314     28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
315     sandbox.h, sandbox_futils.c :
316     Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
317     it is not set, it will revert to its old value.
318    
319     27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
320     Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
321     rather than failing with a violation, bug #29748.
322    
323     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
324     Fix canonicalize() to ignore calls with path = "".
325    
326     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
327     sandbox_futils.c, canonicalize.c :
328     Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
329     call handled strings larger than PATH_MAX (bug #21766). It however does not
330     work the same on 2.4 kernels.
331    
332     To fix, I added the posix implementation of getcwd() (from glibc cvs) that
333     do not need the system call. We use the default getcwd() function via a
334     wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
335     means the current directory was removed, OR that the the system call for
336     getcwd failed (curious is that it do not fail and return NULL or set
337     errno, but rather just truncate the retured directory - usually from the
338     start), and if so, we use the generic getcwd() function (__egetcwd). Note
339     that we do not use the generic version all the time, as it calls lstat()
340     a great number of times, and performance degrade much.
341    
342     29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
343     libsandbox.c :
344     Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
345    
346     22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
347     create-localdecls :
348     When checking path names of files accessed, we need to canonicalize it, else
349     it may be a symlink in a 'write allowed' directory pointing to a file in a
350     directory we should not have write access to.
351    
352     With something like coreutils-5.0, we have two problems:
353     1) One of the tests checks if getcwd() can return a path longer than
354     PATH_MAX. This test then tries to create a dir which even while
355     created local (mkdir("conftest2")), it ends up being resolved with
356     a name that is much larger than PATH_MAX. The problem now is that
357     canonicalize() have undefined behaviour when the path was too long
358     (returned wrongly truncated paths, etc), and pass the wrong path to
359     before_syscall() (causing the bogus sandbox violations).
360     2) The ecanonicalize() function we used, along with the canonicalize()
361     function did not support longer than PATH_MAX. This is partly a
362     cause for 1), but the error checking (rather lack of it) of calls
363     to erealpath() in canonicalize() was the prime reason for 1).
364    
365     As we do not use this canonicalized name to call the function, we resolve this
366     by fixing canonicalize() to do better error checking, and ecanonicalize() as
367     well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
368     While they will resolve paths properly now, and can check if a write/read is
369     allowed, the functions called from the sandboxed environment will still work
370     as expected.
371    
372     This should resolve bug #21766.
373    
374     06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
375     For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
376     it (bug #16298).
377    
378     Problem is that for some reason locale fopen's locale.alias with mode "rm".
379    
380     -------------------------------------------------------
381     nosferatu root # grep fopen locale.log
382     fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
383     nosferatu root #
384     --------------------------------------------------------
385    
386     I checked the source of locale, but it have fopen with mode 'r', so
387     not sure where the "rm" mode comes from. Anyhow, changed the check in
388     before_syscall_open_char() to also see mode "rm" as readonly.
389    
390     23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
391    
392     Add glibc-2.3 support.
393    
394     22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
395    
396     Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
397     operations releated to preload, as well as only try to modify ld.so.preload
398     if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
399     not using ld.so.preload. Fix to not write this instance of sandbox's pid
400     to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
401    
402     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
403    
404     Changed the LD to CC for hppa.
405    
406     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
407    
408     Killed the previous changes I made.
409    
410     17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
411    
412     Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
413    
414     09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
415    
416     Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
417    
418     16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
419    
420     Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
421     for this fix.
422    
423     4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
424    
425     sandbox_futils defined a dirname() function that was masking the same
426     function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
427     '/usr/lib/portage/bi/'). Fixed function to return expected results and
428     renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
429     11231.
430    
431     4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
432    
433     Fix a segfault in libsandbox.c if canonicalize() was called with
434     first parameter = NULL.
435    
436     1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
437    
438     Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
439     cleanup() for this.
440    
441     Change cleanup() in sandbox.c not to exit with fail status if
442     the pidsfile is missing. We really should still display sandbox
443     violations if they occured.
444    
445     31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
446    
447     Update cleanup() in sandbox.c to remove the PIDSFILE if this is
448     the last sandbox running.
449    
450     25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
451    
452     Major cleanups to mainly libsandbox.c again.
453    
454     22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
455    
456     Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
457     parties involved should please contact me so that we can fix it.
458    
459     Add opendir wrapper to libsandbox.c.
460    
461     21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
462    
463     Do some more cleanups to ecanonicalize(), as it dropped filenames in
464     rare cases (after my symlink cleanups), and caused glibc to bork.
465     These fixes went into canonicalize.c.
466    
467     20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
468    
469     Fix spawn_shell() and main() in sandbox.c to properly return fail
470     status.
471    
472     19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
473    
474     The new canonicalize() function in libsandbox.c also resolved symlinks,
475     which caused on cleaning sandbox errors if the symlink pointed to a
476     file in the live root. Ripped out canonicalize() and realpath() from
477     glibc; removed the symlink stuff, and changed them to ecanonicalize()
478     and erealpath().
479    
480     18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
481    
482     Ripped out all the wrappers, and implemented those of InstallWatch.
483     Losts of cleanups and bugfixes. Implement a execve that forces
484     $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
485     /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
486     sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
487     parts; it now have an install target.
488    
489     Reformat the whole thing to look somewhat like the reworked sandbox.c
490     and new sandbox.h and sandbox_futils.c from:
491    
492     Brad House <brad@mainstreetsoftworks.com>.
