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