5 azarah 111 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
6     Use generic getcwd() implementation from uclibc - should be more portable
7     and looks a bit cleaner.
8    
9 azarah 110 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
10     Make sure our true_* pointers are initialized to NULL, and that we check for
11     all references that they are valid.
12    
13 azarah 109 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
14     Be default we will fail if the path name we try to canonicalize is too long.
15     This however could cause issues with some things (bug #94630 and #21766), so
16     if fail_nametoolong == 0, canonicalize() will return a null length string and
17     do not fail.
18    
19 azarah 108 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
20     Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
21     make sure we re-export the new TMPDIR environment variable.
22    
23 azarah 106 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
24     Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
25     by Marcus D. Hanwell <cryos@gentoo.org>.
26    
27 azarah 105 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
28     Add /dev/console to write list, bug #38588.
29    
30 azarah 102 * sandbox-1.2.8 (2005/05/13)
31    
32 azarah 99 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
33 azarah 101 sandbox.h, sandbox_futils.c:
34     General cleanups.
35    
36     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
37 azarah 100 sandbox.h:
38     Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
39    
40     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
41 azarah 99 sandbox.h, sandbox_futils.c:
42     Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
43     to use TMPDIR if present in environment.
44    
45 azarah 98 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
46     Remove sandbox_log_file from main() as its no longer used.
47    
48 azarah 97 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
49     sandbox_futils.c:
50     Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
51     if already exported when sandbox started). Fix get_sandbox_log() and new
52     get_sandbox_debug_log() to not use already exported environment variables if
53     they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
54     SB_PATH_MAX fixes.
55    
56 azarah 94 * sandbox-1.2.7 (2005/05/12)
57    
58 azarah 93 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
59     sandbox_futils.c:
60     More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
61    
62 azarah 92 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
63     Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
64     with '(null)' in it if we did not call sandbox with absolute path.
65    
66 azarah 89 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
67 azarah 91 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
68     for the child.
69    
70     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
71 azarah 90 Remove global preload_adaptable as it is no longer used.
72    
73     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
74 azarah 89 Rewrite environment stuff to only be set when execve'ing the child process
75     to try and avoid issues like bug #91541 that causes sandbox to crash if
76     we set LD_PRELOAD sandbox side already.
77    
78 azarah 87 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
79 azarah 88 Move print_sandbox_log() up to make things neater.
80    
81     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
82 azarah 87 Remove load_preload_libs(), as its not used anymore.
83    
84 azarah 83 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
85 azarah 86 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
86    
87     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
88 azarah 84 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
89    
90     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
91 azarah 83 Remove ld.so.preload crap - we are not going to use it again.
92    
93 azarah 82 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
94     Fix typo in code that checks if we got valid group information, causing a
95     segmentation fault, bug #91637.
96    
97 azarah 79 * sandbox-1.2.6 (2005/05/10)
98    
99 azarah 78 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
100     Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
101     for some odd reason, bug #91541.
102    
103 azarah 77 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
104     Fix typo (sizeof -> strlen).
105    
106 ferringb 76 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
107     rewrote the sbcontext caching code so it accounts for env changes since lib
108     initialization.
109    
110 azarah 75 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
111     We create libctest.c via configure, so no need to keep it around. Do some
112     cleanup related to libctest.c and libctest during configure.
113    
114 azarah 74 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
115     Add rename support of symlinks pointing to protected files/directories.
116    
117 azarah 72 * sandbox-1.2.5 (2005/05/04)
118    
119 azarah 71 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
120     sandbox.bashrc:
121     Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
122     already set, init of the env vars fails for some reason, so do this later on,
123     and do not warn (bug #91431).
124    
125 azarah 70 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
126     sandbox.bashrc:
127     Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
128    
129 azarah 68 * sandbox-1.2.4 (2005/05/03)
130    
131 azarah 66 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
132     Do not init the env entries with each call, as it creates too many calls to
133 azarah 67 lstat, etc. Should speedup things a bit, bug #91040.
134 azarah 66
135 azarah 65 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
136     Add /dev/pty to default write list. Noticed by Morfic.
137    
138 vapier 62 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
139     sandbox.h:
140     uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
141     exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
142    
143 azarah 59 * sandbox-1.2.3 (2005/04/29)
144    
145 azarah 56 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
146     Do not check for (*&#$(* CXX or F77.
147    
148 azarah 54 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
149     Do not append '/' to pathname in filter_path() if it already ends with it.
150    
151 vapier 53 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
152     With az's help, clean up autotools to work with cross-compiling.
153    
154 azarah 59 * sandbox-1.2.2 (2005/04/28)
155 azarah 48
156 azarah 47 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
157     Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
158     have issues; bug #90592.
159    
160 azarah 59 * sandbox-1.2.1 (2005/04/23)
161 azarah 44
162 azarah 43 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
163     getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
164     Make sure all functions used in libsandbox.c is declared static. Define
165     SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
166     linking with its object. Hopefully this will fix bug #90153.
167    
168 azarah 59 * sandbox-1.2 (2005/04/23)
169 azarah 46
170 azarah 40 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
171     Allow lchown a symlink in write-allowed path pointing to write-denied
172     target.
173    
174 genone 39 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
175     Also show resolved symlink names in the log.
176    
177 azarah 37 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
178     Seems -nostdlib was the problem with the constructor/destructor - remove it
179     from Makefile.am, and change the constructor/destructor names again.
180    
181 azarah 36 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
182     Also rename the _init() and _fini() declarations.
183    
184 azarah 35 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
185     Fixup the constructor/destructor function names again (they should be _init()
186     and _fini() it seems, and not being called caused sandbox_lib_path to be
187     unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
188     Add both the path in given SANDBOX_x variable, as well as its symlink
189     resolved path in init_env_entries(). Modify filter_path() to be able to
190     resolve paths without resolving symlinks, as well as to be able to resolve
191     symlinks. Fix a possible segfault in check_access(). Add symlink resolving
192     to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
193     for bug #31019 cause access violations if we try to remove a symlink that is
194     not in protected path, but points to a protected path. Fix a memory leak in
195     sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
196     (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
197     (pid_string was uninitialized). General syntax cleanups.
198    
199 ferringb 34 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
200     infamous "pids file is not a regular file" w/out newline bug.
201    
202 ferringb 33 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
203     Correct libc_version path detection, since it was screwing up if libdir !=
204     "/lib/".
205    
206     02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
207 azarah 32 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
208    
209 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
210 azarah 31 Fix symbols.in not added to dist.
211    
212 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
213 azarah 30 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
214     White space fixes.
215    
216 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
217 azarah 30 configure.in, getcwd.c, libsandbox.c, symbols.in:
218 azarah 29 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
219     getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
220     for glibc and other libc's that use this. Update libsandbox.c to use these
221     symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
222     process unset it.
223    
224 ferringb 33 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
225 ferringb 28 killed off _init and _fini in favor of
226     void __attribute__ ((constructor)) init_func and
227     void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
228    
229 ferringb 26 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
230     canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
231     having the hick-ups.
232    
233 ferringb 24 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
234     Makefile.am: Fixed compilation.
235    
236 ferringb 18 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
237     Gutted the bugger so it stops checking for a c++ and fortran compiler.
238     Do *not* regenerate aclocal.m4 for making a release until a better
239     solution is created.
240    
241 ferringb 16 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
242     Removal of more hardcoded paths.
243    
244 ferringb 13 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
245     sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
246    
247     19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
248 ferringb 6 Sandbox is now autotooled, create-localdecls needs to be killed and the code
249     shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
250     are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
251     To get to a point of testing, automake && autoconf; created requisite files w/
252     a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
253     /lib and /usr/lib/portage/bin.
254    
255 ferringb 2 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
256     closing out bug #70225, potential overflow of the sandbox_pids_file var.
257    
258     07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
259     (think it was at least) allows intermixing of code and data segments. bug #70351
260     should be fixed by this.
261    
262     03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
263     futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
264    
265     02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
266     Seth Robertson that tracked down all adjuct flags for read operations that
267     do not invoke a write operation.
268    
269     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
270     Another fix from jstubbs regarding a free() on a stack variable for the
271     environment -- tracking now prevents extraneous free()'s segfault.
272    
273     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
274     J. Stubbs tracked down a new bug where mkdir was failing to the patch on
275     the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
276     Also remove the errno = ESUCCESS settings as documentation points out that
277     a library isn't allowed to do that.
278    
279     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
280     file_security_check() function to check random potential exploits on files
281     that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
282     the 'system-crippling' exploits (bug 21923) and catches a few other
283     potential problems.
284    
285     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
286     32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
287    
288     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
289     bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
290     Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
291    
292     29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
293     Fix permissions and group of pids file and logs. Permissions should be 0664
294     and group should be 'portage'. Bug #34260.
295    
296     28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
297     Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
298     to the real execve (in our execve wrapper). Seems that on some arches (sparc
299     among others) do not allow us to tamper with the readonly copy passed to
300     execve, so pass our own copy of the environment. Bug #42290.
301    
302     11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
303     Changed tail to head and added a notice about duration of glibc check.
304    
305     21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
306     Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
307     as there isn't a guarentee that it is dynamic.
308    
309     02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
310     If 'file' passed to before_syscall(const char *func, const char *file) is
311     invalid, we should set errno to ENOENT, and not EINVAL. This should
312     close bug #32238.
313    
314     14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
315     Fix a bug that occurs mainly on 64bit arch, where the file passed to
316     the functions we wrap, is invalid, and then cause canonicalize to pass
317     garbage to before_syscall(), thanks to great detective work from
318     Andrea Luzzardi <al@sig11.org> (bug #29846).
319    
320     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
321     Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
322    
323     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
324     Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
325     only checked the destination patch, and not the source, so we could move
326     a protected file to a unprotected directory, and then delete/modify it.
327     Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
328    
329     12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
330     Added python2.3 to the predict section/variable.
331    
332     28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
333     sandbox.h, sandbox_futils.c :
334     Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
335     it is not set, it will revert to its old value.
336    
337     27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
338     Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
339     rather than failing with a violation, bug #29748.
340    
341     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
342     Fix canonicalize() to ignore calls with path = "".
343    
344     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
345     sandbox_futils.c, canonicalize.c :
346     Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
347     call handled strings larger than PATH_MAX (bug #21766). It however does not
348     work the same on 2.4 kernels.
349    
350     To fix, I added the posix implementation of getcwd() (from glibc cvs) that
351     do not need the system call. We use the default getcwd() function via a
352     wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
353     means the current directory was removed, OR that the the system call for
354     getcwd failed (curious is that it do not fail and return NULL or set
355     errno, but rather just truncate the retured directory - usually from the
356     start), and if so, we use the generic getcwd() function (__egetcwd). Note
357     that we do not use the generic version all the time, as it calls lstat()
358     a great number of times, and performance degrade much.
359    
360     29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
361     libsandbox.c :
362     Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
363    
364     22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
365     create-localdecls :
366     When checking path names of files accessed, we need to canonicalize it, else
367     it may be a symlink in a 'write allowed' directory pointing to a file in a
368     directory we should not have write access to.
369    
370     With something like coreutils-5.0, we have two problems:
371     1) One of the tests checks if getcwd() can return a path longer than
372     PATH_MAX. This test then tries to create a dir which even while
373     created local (mkdir("conftest2")), it ends up being resolved with
374     a name that is much larger than PATH_MAX. The problem now is that
375     canonicalize() have undefined behaviour when the path was too long
376     (returned wrongly truncated paths, etc), and pass the wrong path to
377     before_syscall() (causing the bogus sandbox violations).
378     2) The ecanonicalize() function we used, along with the canonicalize()
379     function did not support longer than PATH_MAX. This is partly a
380     cause for 1), but the error checking (rather lack of it) of calls
381     to erealpath() in canonicalize() was the prime reason for 1).
382    
383     As we do not use this canonicalized name to call the function, we resolve this
384     by fixing canonicalize() to do better error checking, and ecanonicalize() as
385     well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
386     While they will resolve paths properly now, and can check if a write/read is
387     allowed, the functions called from the sandboxed environment will still work
388     as expected.
389    
390     This should resolve bug #21766.
391    
392     06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
393     For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
394     it (bug #16298).
395    
396     Problem is that for some reason locale fopen's locale.alias with mode "rm".
397    
398     -------------------------------------------------------
399     nosferatu root # grep fopen locale.log
400     fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
401     nosferatu root #
402     --------------------------------------------------------
403    
404     I checked the source of locale, but it have fopen with mode 'r', so
405     not sure where the "rm" mode comes from. Anyhow, changed the check in
406     before_syscall_open_char() to also see mode "rm" as readonly.
407    
408     23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
409    
410     Add glibc-2.3 support.
411    
412     22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
413    
414     Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
415     operations releated to preload, as well as only try to modify ld.so.preload
416     if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
417     not using ld.so.preload. Fix to not write this instance of sandbox's pid
418     to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
419    
420     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
421    
422     Changed the LD to CC for hppa.
423    
424     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
425    
426     Killed the previous changes I made.
427    
428     17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
429    
430     Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
431    
432     09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
433    
434     Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
435    
436     16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
437    
438     Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
439     for this fix.
440    
441     4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
442    
443     sandbox_futils defined a dirname() function that was masking the same
444     function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
445     '/usr/lib/portage/bi/'). Fixed function to return expected results and
446     renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
447     11231.
448    
449     4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
450    
451     Fix a segfault in libsandbox.c if canonicalize() was called with
452     first parameter = NULL.
453    
454     1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
455    
456     Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
457     cleanup() for this.
458    
459     Change cleanup() in sandbox.c not to exit with fail status if
460     the pidsfile is missing. We really should still display sandbox
461     violations if they occured.
462    
463     31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
464    
465     Update cleanup() in sandbox.c to remove the PIDSFILE if this is
466     the last sandbox running.
467    
468     25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
469    
470     Major cleanups to mainly libsandbox.c again.
471    
472     22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
473    
474     Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
475     parties involved should please contact me so that we can fix it.
476    
477     Add opendir wrapper to libsandbox.c.
478    
479     21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
480    
481     Do some more cleanups to ecanonicalize(), as it dropped filenames in
482     rare cases (after my symlink cleanups), and caused glibc to bork.
483     These fixes went into canonicalize.c.
484    
485     20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
486    
487     Fix spawn_shell() and main() in sandbox.c to properly return fail
488     status.
489    
490     19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
491    
492     The new canonicalize() function in libsandbox.c also resolved symlinks,
493     which caused on cleaning sandbox errors if the symlink pointed to a
494     file in the live root. Ripped out canonicalize() and realpath() from
495     glibc; removed the symlink stuff, and changed them to ecanonicalize()
496     and erealpath().
497    
498     18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
499    
500     Ripped out all the wrappers, and implemented those of InstallWatch.
501     Losts of cleanups and bugfixes. Implement a execve that forces
502     $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
503     /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
504     sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
505     parts; it now have an install target.
506    
507     Reformat the whole thing to look somewhat like the reworked sandbox.c
508     and new sandbox.h and sandbox_futils.c from:
509    
510     Brad House <brad@mainstreetsoftworks.com>.
