Be default we will fail if the path name we try to canonicalize is too long.
This however could cause issues with some things (bug #94630 and #21766), so
if fail_nametoolong == 0, canonicalize() will return a null length string and
do not fail.

5 azarah 109 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6     Be default we will fail if the path name we try to canonicalize is too long.
7     This however could cause issues with some things (bug #94630 and #21766), so
8     if fail_nametoolong == 0, canonicalize() will return a null length string and
9     do not fail.
10    
11 azarah 108 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
12     Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
13     make sure we re-export the new TMPDIR environment variable.
14    
15 azarah 106 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
16     Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
17     by Marcus D. Hanwell <cryos@gentoo.org>.
18    
19 azarah 105 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
20     Add /dev/console to write list, bug #38588.
21    
22 azarah 102 * sandbox-1.2.8 (2005/05/13)
23    
24 azarah 99 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
25 azarah 101 sandbox.h, sandbox_futils.c:
26     General cleanups.
27    
28     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
29 azarah 100 sandbox.h:
30     Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
31    
32     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
33 azarah 99 sandbox.h, sandbox_futils.c:
34     Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
35     to use TMPDIR if present in environment.
36    
37 azarah 98 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
38     Remove sandbox_log_file from main() as its no longer used.
39    
40 azarah 97 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
41     sandbox_futils.c:
42     Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
43     if already exported when sandbox started). Fix get_sandbox_log() and new
44     get_sandbox_debug_log() to not use already exported environment variables if
45     they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
46     SB_PATH_MAX fixes.
47    
48 azarah 94 * sandbox-1.2.7 (2005/05/12)
49    
50 azarah 93 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
51     sandbox_futils.c:
52     More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
53    
54 azarah 92 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
55     Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
56     with '(null)' in it if we did not call sandbox with absolute path.
57    
58 azarah 89 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
59 azarah 91 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
60     for the child.
61    
62     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
63 azarah 90 Remove global preload_adaptable as it is no longer used.
64    
65     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
66 azarah 89 Rewrite environment stuff to only be set when execve'ing the child process
67     to try and avoid issues like bug #91541 that causes sandbox to crash if
68     we set LD_PRELOAD sandbox side already.
69    
70 azarah 87 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
71 azarah 88 Move print_sandbox_log() up to make things neater.
72    
73     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
74 azarah 87 Remove load_preload_libs(), as its not used anymore.
75    
76 azarah 83 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
77 azarah 86 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
78    
79     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
80 azarah 84 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
81    
82     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
83 azarah 83 Remove ld.so.preload crap - we are not going to use it again.
84    
85 azarah 82 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
86     Fix typo in code that checks if we got valid group information, causing a
87     segmentation fault, bug #91637.
88    
89 azarah 79 * sandbox-1.2.6 (2005/05/10)
90    
91 azarah 78 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
92     Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
93     for some odd reason, bug #91541.
94    
95 azarah 77 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
96     Fix typo (sizeof -> strlen).
97    
98 ferringb 76 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
99     rewrote the sbcontext caching code so it accounts for env changes since lib
100     initialization.
101    
102 azarah 75 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
103     We create libctest.c via configure, so no need to keep it around. Do some
104     cleanup related to libctest.c and libctest during configure.
105    
106 azarah 74 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
107     Add rename support of symlinks pointing to protected files/directories.
108    
109 azarah 72 * sandbox-1.2.5 (2005/05/04)
110    
111 azarah 71 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
112     sandbox.bashrc:
113     Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
114     already set, init of the env vars fails for some reason, so do this later on,
115     and do not warn (bug #91431).
116    
117 azarah 70 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
118     sandbox.bashrc:
119     Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
120    
121 azarah 68 * sandbox-1.2.4 (2005/05/03)
122    
123 azarah 66 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
124     Do not init the env entries with each call, as it creates too many calls to
125 azarah 67 lstat, etc. Should speedup things a bit, bug #91040.
126 azarah 66
127 azarah 65 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
128     Add /dev/pty to default write list. Noticed by Morfic.
129    
130 vapier 62 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
131     sandbox.h:
132     uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
133     exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
134    
135 azarah 59 * sandbox-1.2.3 (2005/04/29)
136    
137 azarah 56 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
138     Do not check for (*&#$(* CXX or F77.
139    
140 azarah 54 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
141     Do not append '/' to pathname in filter_path() if it already ends with it.
142    
143 vapier 53 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
144     With az's help, clean up autotools to work with cross-compiling.
145    
146 azarah 59 * sandbox-1.2.2 (2005/04/28)
147 azarah 48
148 azarah 47 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
149     Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
150     have issues; bug #90592.
151    
152 azarah 59 * sandbox-1.2.1 (2005/04/23)
153 azarah 44
154 azarah 43 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
155     getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
156     Make sure all functions used in libsandbox.c is declared static. Define
157     SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
158     linking with its object. Hopefully this will fix bug #90153.
159    
160 azarah 59 * sandbox-1.2 (2005/04/23)
161 azarah 46
162 azarah 40 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
163     Allow lchown a symlink in write-allowed path pointing to write-denied
164     target.
165    
166 genone 39 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
167     Also show resolved symlink names in the log.
168    
169 azarah 37 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
170     Seems -nostdlib was the problem with the constructor/destructor - remove it
171     from Makefile.am, and change the constructor/destructor names again.
172    
173 azarah 36 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
174     Also rename the _init() and _fini() declarations.
175    
176 azarah 35 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
177     Fixup the constructor/destructor function names again (they should be _init()
178     and _fini() it seems, and not being called caused sandbox_lib_path to be
179     unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
180     Add both the path in given SANDBOX_x variable, as well as its symlink
181     resolved path in init_env_entries(). Modify filter_path() to be able to
182     resolve paths without resolving symlinks, as well as to be able to resolve
183     symlinks. Fix a possible segfault in check_access(). Add symlink resolving
184     to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
185     for bug #31019 cause access violations if we try to remove a symlink that is
186     not in protected path, but points to a protected path. Fix a memory leak in
187     sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
188     (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
189     (pid_string was uninitialized). General syntax cleanups.
190    
191 ferringb 34 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
192     infamous "pids file is not a regular file" w/out newline bug.
193    
194 ferringb 33 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
195     Correct libc_version path detection, since it was screwing up if libdir !=
196     "/lib/".
197    
198     02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
199 azarah 32 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
200    
201 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
202 azarah 31 Fix symbols.in not added to dist.
203    
204 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
205 azarah 30 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
206     White space fixes.
207    
208 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
209 azarah 30 configure.in, getcwd.c, libsandbox.c, symbols.in:
210 azarah 29 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
211     getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
212     for glibc and other libc's that use this. Update libsandbox.c to use these
213     symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
214     process unset it.
215    
216 ferringb 33 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
217 ferringb 28 killed off _init and _fini in favor of
218     void __attribute__ ((constructor)) init_func and
219     void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
220    
221 ferringb 26 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
222     canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
223     having the hick-ups.
224    
225 ferringb 24 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
226     Makefile.am: Fixed compilation.
227    
228 ferringb 18 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
229     Gutted the bugger so it stops checking for a c++ and fortran compiler.
230     Do *not* regenerate aclocal.m4 for making a release until a better
231     solution is created.
232    
233 ferringb 16 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
234     Removal of more hardcoded paths.
235    
236 ferringb 13 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
237     sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
238    
239     19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
240 ferringb 6 Sandbox is now autotooled, create-localdecls needs to be killed and the code
241     shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
242     are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
243     To get to a point of testing, automake && autoconf; created requisite files w/
244     a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
245     /lib and /usr/lib/portage/bin.
246    
247 ferringb 2 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
248     closing out bug #70225, potential overflow of the sandbox_pids_file var.
249    
250     07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
251     (think it was at least) allows intermixing of code and data segments. bug #70351
252     should be fixed by this.
253    
254     03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
255     futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
256    
257     02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
258     Seth Robertson that tracked down all adjuct flags for read operations that
259     do not invoke a write operation.
260    
261     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
262     Another fix from jstubbs regarding a free() on a stack variable for the
263     environment -- tracking now prevents extraneous free()'s segfault.
264    
265     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
266     J. Stubbs tracked down a new bug where mkdir was failing to the patch on
267     the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
268     Also remove the errno = ESUCCESS settings as documentation points out that
269     a library isn't allowed to do that.
270    
271     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
272     file_security_check() function to check random potential exploits on files
273     that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
274     the 'system-crippling' exploits (bug 21923) and catches a few other
275     potential problems.
276    
277     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
278     32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
279    
280     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
281     bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
282     Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
283    
284     29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
285     Fix permissions and group of pids file and logs. Permissions should be 0664
286     and group should be 'portage'. Bug #34260.
287    
288     28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
289     Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
290     to the real execve (in our execve wrapper). Seems that on some arches (sparc
291     among others) do not allow us to tamper with the readonly copy passed to
292     execve, so pass our own copy of the environment. Bug #42290.
293    
294     11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
295     Changed tail to head and added a notice about duration of glibc check.
296    
297     21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
298     Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
299     as there isn't a guarentee that it is dynamic.
300    
301     02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
302     If 'file' passed to before_syscall(const char *func, const char *file) is
303     invalid, we should set errno to ENOENT, and not EINVAL. This should
304     close bug #32238.
305    
306     14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
307     Fix a bug that occurs mainly on 64bit arch, where the file passed to
308     the functions we wrap, is invalid, and then cause canonicalize to pass
309     garbage to before_syscall(), thanks to great detective work from
310     Andrea Luzzardi <al@sig11.org> (bug #29846).
311    
312     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
313     Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
314    
315     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
316     Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
317     only checked the destination patch, and not the source, so we could move
318     a protected file to a unprotected directory, and then delete/modify it.
319     Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
320    
321     12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
322     Added python2.3 to the predict section/variable.
323    
324     28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
325     sandbox.h, sandbox_futils.c :
326     Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
327     it is not set, it will revert to its old value.
328    
329     27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
330     Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
331     rather than failing with a violation, bug #29748.
332    
333     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
334     Fix canonicalize() to ignore calls with path = "".
335    
336     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
337     sandbox_futils.c, canonicalize.c :
338     Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
339     call handled strings larger than PATH_MAX (bug #21766). It however does not
340     work the same on 2.4 kernels.
341    
342     To fix, I added the posix implementation of getcwd() (from glibc cvs) that
343     do not need the system call. We use the default getcwd() function via a
344     wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
345     means the current directory was removed, OR that the the system call for
346     getcwd failed (curious is that it do not fail and return NULL or set
347     errno, but rather just truncate the retured directory - usually from the
348     start), and if so, we use the generic getcwd() function (__egetcwd). Note
349     that we do not use the generic version all the time, as it calls lstat()
350     a great number of times, and performance degrade much.

352     29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
353     libsandbox.c :
354     Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
355    
356     22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
357     create-localdecls :
358     When checking path names of files accessed, we need to canonicalize it, else
359     it may be a symlink in a 'write allowed' directory pointing to a file in a
360     directory we should not have write access to.
361    
362     With something like coreutils-5.0, we have two problems:
363     1) One of the tests checks if getcwd() can return a path longer than
364     PATH_MAX. This test then tries to create a dir which even while
365     created local (mkdir("conftest2")), it ends up being resolved with
366     a name that is much larger than PATH_MAX. The problem now is that
367     canonicalize() have undefined behaviour when the path was too long
368     (returned wrongly truncated paths, etc), and pass the wrong path to
369     before_syscall() (causing the bogus sandbox violations).
370     2) The ecanonicalize() function we used, along with the canonicalize()
371     function did not support longer than PATH_MAX. This is partly a
372     cause for 1), but the error checking (rather lack of it) of calls
373     to erealpath() in canonicalize() was the prime reason for 1).
374    
375     As we do not use this canonicalized name to call the function, we resolve this
376     by fixing canonicalize() to do better error checking, and ecanonicalize() as
377     well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
378     While they will resolve paths properly now, and can check if a write/read is
379     allowed, the functions called from the sandboxed environment will still work
380     as expected.
381    
382     This should resolve bug #21766.
383    
384     06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
385     For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
386     it (bug #16298).
387    
388     Problem is that for some reason locale fopen's locale.alias with mode "rm".
389    
390     -------------------------------------------------------
391     nosferatu root # grep fopen locale.log
392     fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
393     nosferatu root #
394     --------------------------------------------------------
395    
396     I checked the source of locale, but it have fopen with mode 'r', so
397     not sure where the "rm" mode comes from. Anyhow, changed the check in
398     before_syscall_open_char() to also see mode "rm" as readonly.
399    
400     23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
401    
402     Add glibc-2.3 support.
403    
404     22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
405    
406     Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
407     operations releated to preload, as well as only try to modify ld.so.preload
408     if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
409     not using ld.so.preload. Fix to not write this instance of sandbox's pid
410     to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
411    
412     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
413    
414     Changed the LD to CC for hppa.
415    
416     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
417    
418     Killed the previous changes I made.
419    
420     17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
421    
422     Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
423    
424     09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
425    
426     Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
427    
428     16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
429    
430     Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
431     for this fix.
432    
433     4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
434    
435     sandbox_futils defined a dirname() function that was masking the same
436     function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
437     '/usr/lib/portage/bi/'). Fixed function to return expected results and
438     renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
439     11231.
440    
441     4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
442    
443     Fix a segfault in libsandbox.c if canonicalize() was called with
444     first parameter = NULL.
445    
446     1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
447    
448     Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
449     cleanup() for this.
450    
451     Change cleanup() in sandbox.c not to exit with fail status if
452     the pidsfile is missing. We really should still display sandbox
453     violations if they occured.
454    
455     31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
456    
457     Update cleanup() in sandbox.c to remove the PIDSFILE if this is
458     the last sandbox running.
459    
460     25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
461    
462     Major cleanups to mainly libsandbox.c again.
463    
464     22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
465    
466     Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
467     parties involved should please contact me so that we can fix it.
468    
469     Add opendir wrapper to libsandbox.c.
470    
471     21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
472    
473     Do some more cleanups to ecanonicalize(), as it dropped filenames in
474     rare cases (after my symlink cleanups), and caused glibc to bork.
475     These fixes went into canonicalize.c.
476    
477     20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
478    
479     Fix spawn_shell() and main() in sandbox.c to properly return fail
480     status.
481    
482     19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
483    
484     The new canonicalize() function in libsandbox.c also resolved symlinks,
485     which caused on cleaning sandbox errors if the symlink pointed to a
486     file in the live root. Ripped out canonicalize() and realpath() from
487     glibc; removed the symlink stuff, and changed them to ecanonicalize()
488     and erealpath().
489    
490     18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
491    
492     Ripped out all the wrappers, and implemented those of InstallWatch.
493     Losts of cleanups and bugfixes. Implement a execve that forces
494     $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
495     /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
496     sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
497     parts; it now have an install target.
498    
499     Reformat the whole thing to look somewhat like the reworked sandbox.c
500     and new sandbox.h and sandbox_futils.c from:
501    
502     Brad House <brad@mainstreetsoftworks.com>.
