4    
5 azarah 118 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
6     More comment/readability cleanups.
7    
8 azarah 117 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
9     sandbox_futils.c, libsandbox.c:
10     Some strncpy/strncat and other cleanups.
11    
12 azarah 115 * sandbox-1.2.9 (2005/06/09)
13    
14 azarah 114 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
15     Move symlink hack down a bit to try and minimize on the amount of lstat()
16     calls we do.
17    
18 azarah 113 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
19     Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
20    
21 azarah 112 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
22     Add wrapper for access() function, bug #85413.
23    
24 azarah 111 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
25     Use generic getcwd() implementation from uclibc - should be more portable
26     and looks a bit cleaner.
27    
28 azarah 110 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
29     Make sure our true_* pointers are initialized to NULL, and that we check for
30     all references that they are valid.
31    
32 azarah 109 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
33     Be default we will fail if the path name we try to canonicalize is too long.
34     This however could cause issues with some things (bug #94630 and #21766), so
35     if fail_nametoolong == 0, canonicalize() will return a null length string and
36     do not fail.
37    
38 azarah 108 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
39     Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
40     make sure we re-export the new TMPDIR environment variable.
41    
42 azarah 106 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
43     Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
44     by Marcus D. Hanwell <cryos@gentoo.org>.
45    
46 azarah 105 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
47     Add /dev/console to write list, bug #38588.
48    
49 azarah 102 * sandbox-1.2.8 (2005/05/13)
50    
51 azarah 99 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
52 azarah 101 sandbox.h, sandbox_futils.c:
53     General cleanups.
54    
55     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
56 azarah 100 sandbox.h:
57     Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
58    
59     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
60 azarah 99 sandbox.h, sandbox_futils.c:
61     Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
62     to use TMPDIR if present in environment.
63    
64 azarah 98 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
65     Remove sandbox_log_file from main() as its no longer used.
66    
67 azarah 97 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
68     sandbox_futils.c:
69     Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
70     if already exported when sandbox started). Fix get_sandbox_log() and new
71     get_sandbox_debug_log() to not use already exported environment variables if
72     they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
73     SB_PATH_MAX fixes.
74    
75 azarah 94 * sandbox-1.2.7 (2005/05/12)
76    
77 azarah 93 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
78     sandbox_futils.c:
79     More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
80    
81 azarah 92 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
82     Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
83     with '(null)' in it if we did not call sandbox with absolute path.
84    
85 azarah 89 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
86 azarah 91 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
87     for the child.
88    
89     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
90 azarah 90 Remove global preload_adaptable as it is no longer used.
91    
92     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
93 azarah 89 Rewrite environment stuff to only be set when execve'ing the child process
94     to try and avoid issues like bug #91541 that causes sandbox to crash if
95     we set LD_PRELOAD sandbox side already.
96    
97 azarah 87 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
98 azarah 88 Move print_sandbox_log() up to make things neater.
99    
100     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
101 azarah 87 Remove load_preload_libs(), as its not used anymore.
102    
103 azarah 83 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
104 azarah 86 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
105    
106     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
107 azarah 84 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
108    
109     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
110 azarah 83 Remove ld.so.preload crap - we are not going to use it again.
111    
112 azarah 82 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
113     Fix typo in code that checks if we got valid group information, causing a
114     segmentation fault, bug #91637.
115    
116 azarah 79 * sandbox-1.2.6 (2005/05/10)
117    
118 azarah 78 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
119     Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
120     for some odd reason, bug #91541.
121    
122 azarah 77 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
123     Fix typo (sizeof -> strlen).
124    
125 ferringb 76 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
126     rewrote the sbcontext caching code so it accounts for env changes since lib
127     initialization.
128    
129 azarah 75 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
130     We create libctest.c via configure, so no need to keep it around. Do some
131     cleanup related to libctest.c and libctest during configure.
132    
133 azarah 74 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
134     Add rename support of symlinks pointing to protected files/directories.
135    
136 azarah 72 * sandbox-1.2.5 (2005/05/04)
137    
138 azarah 71 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
139     sandbox.bashrc:
140     Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
141     already set, init of the env vars fails for some reason, so do this later on,
142     and do not warn (bug #91431).
143    
144 azarah 70 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
145     sandbox.bashrc:
146     Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
147    
148 azarah 68 * sandbox-1.2.4 (2005/05/03)
149    
150 azarah 66 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
151     Do not init the env entries with each call, as it creates too many calls to
152 azarah 67 lstat, etc. Should speedup things a bit, bug #91040.
153 azarah 66
154 azarah 65 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
155     Add /dev/pty to default write list. Noticed by Morfic.
156    
157 vapier 62 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
158     sandbox.h:
159     uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
160     exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
161    
162 azarah 59 * sandbox-1.2.3 (2005/04/29)
163    
164 azarah 56 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
165     Do not check for (*&#$(* CXX or F77.
166    
167 azarah 54 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
168     Do not append '/' to pathname in filter_path() if it already ends with it.
169    
170 vapier 53 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
171     With az's help, clean up autotools to work with cross-compiling.
172    
173 azarah 59 * sandbox-1.2.2 (2005/04/28)
174 azarah 48
175 azarah 47 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
176     Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
177     have issues; bug #90592.
178    
179 azarah 59 * sandbox-1.2.1 (2005/04/23)
180 azarah 44
181 azarah 43 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
182     getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
183     Make sure all functions used in libsandbox.c is declared static. Define
184     SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
185     linking with its object. Hopefully this will fix bug #90153.
186    
187 azarah 59 * sandbox-1.2 (2005/04/23)
188 azarah 46
189 azarah 40 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
190     Allow lchown a symlink in write-allowed path pointing to write-denied
191     target.
192    
193 genone 39 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
194     Also show resolved symlink names in the log.
195    
196 azarah 37 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
197     Seems -nostdlib was the problem with the constructor/destructor - remove it
198     from Makefile.am, and change the constructor/destructor names again.
199    
200 azarah 36 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
201     Also rename the _init() and _fini() declarations.
202    
203 azarah 35 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
204     Fixup the constructor/destructor function names again (they should be _init()
205     and _fini() it seems, and not being called caused sandbox_lib_path to be
206     unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
207     Add both the path in given SANDBOX_x variable, as well as its symlink
208     resolved path in init_env_entries(). Modify filter_path() to be able to
209     resolve paths without resolving symlinks, as well as to be able to resolve
210     symlinks. Fix a possible segfault in check_access(). Add symlink resolving
211     to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
212     for bug #31019 cause access violations if we try to remove a symlink that is
213     not in protected path, but points to a protected path. Fix a memory leak in
214     sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
215     (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
216     (pid_string was uninitialized). General syntax cleanups.
217    
218 ferringb 34 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
219     infamous "pids file is not a regular file" w/out newline bug.
220    
221 ferringb 33 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
222     Correct libc_version path detection, since it was screwing up if libdir !=
223     "/lib/".
224    
225     02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
226 azarah 32 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
227    
228 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
229 azarah 31 Fix symbols.in not added to dist.
230    
231 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
232 azarah 30 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
233     White space fixes.
234    
235 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
236 azarah 30 configure.in, getcwd.c, libsandbox.c, symbols.in:
237 azarah 29 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
238     getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
239     for glibc and other libc's that use this. Update libsandbox.c to use these
240     symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
241     process unset it.
242    
243 ferringb 33 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
244 ferringb 28 killed off _init and _fini in favor of
245     void __attribute__ ((constructor)) init_func and
246     void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
247    
248 ferringb 26 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
249     canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
250     having the hick-ups.
251    
252 ferringb 24 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
253     Makefile.am: Fixed compilation.
254    
255 ferringb 18 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
256     Gutted the bugger so it stops checking for a c++ and fortran compiler.
257     Do *not* regenerate aclocal.m4 for making a release until a better
258     solution is created.
259    
260 ferringb 16 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
261     Removal of more hardcoded paths.
262    
263 ferringb 13 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
264     sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
265    
266     19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
267 ferringb 6 Sandbox is now autotooled, create-localdecls needs to be killed and the code
268     shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
269     are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
270     To get to a point of testing, automake && autoconf; created requisite files w/
271     a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
272     /lib and /usr/lib/portage/bin.
273    
274 ferringb 2 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
275     closing out bug #70225, potential overflow of the sandbox_pids_file var.
276    
277     07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
278     (think it was at least) allows intermixing of code and data segments. bug #70351
279     should be fixed by this.
280    
281     03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
282     futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
283    
284     02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
285     Seth Robertson that tracked down all adjuct flags for read operations that
286     do not invoke a write operation.
287    
288     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
289     Another fix from jstubbs regarding a free() on a stack variable for the
290     environment -- tracking now prevents extraneous free()'s segfault.
291    
292     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
293     J. Stubbs tracked down a new bug where mkdir was failing to the patch on
294     the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
295     Also remove the errno = ESUCCESS settings as documentation points out that
296     a library isn't allowed to do that.
297    
298     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
299     file_security_check() function to check random potential exploits on files
300     that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
301     the 'system-crippling' exploits (bug 21923) and catches a few other
302     potential problems.
303    
304     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
305     32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
306    
307     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
308     bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
309     Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
310    
311     29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
312     Fix permissions and group of pids file and logs. Permissions should be 0664
313     and group should be 'portage'. Bug #34260.
314    
315     28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
316     Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
317     to the real execve (in our execve wrapper). Seems that on some arches (sparc
318     among others) do not allow us to tamper with the readonly copy passed to
319     execve, so pass our own copy of the environment. Bug #42290.
320    
321     11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
322     Changed tail to head and added a notice about duration of glibc check.
323    
324     21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
325     Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
326     as there isn't a guarentee that it is dynamic.
327    
328     02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
329     If 'file' passed to before_syscall(const char *func, const char *file) is
330     invalid, we should set errno to ENOENT, and not EINVAL. This should
331     close bug #32238.
332    
333     14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
334     Fix a bug that occurs mainly on 64bit arch, where the file passed to
335     the functions we wrap, is invalid, and then cause canonicalize to pass
336     garbage to before_syscall(), thanks to great detective work from
337     Andrea Luzzardi <al@sig11.org> (bug #29846).
338    
339     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
340     Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
341    
342     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
343     Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
344     only checked the destination patch, and not the source, so we could move
345     a protected file to a unprotected directory, and then delete/modify it.
346     Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
347    
348     12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
349     Added python2.3 to the predict section/variable.
350    
351     28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
352     sandbox.h, sandbox_futils.c :
353     Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
354     it is not set, it will revert to its old value.
355    
356     27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
357     Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
358     rather than failing with a violation, bug #29748.
359    
360     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
361     Fix canonicalize() to ignore calls with path = "".
362    
363     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
364     sandbox_futils.c, canonicalize.c :
365     Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
366     call handled strings larger than PATH_MAX (bug #21766). It however does not
367     work the same on 2.4 kernels.
368    
369     To fix, I added the posix implementation of getcwd() (from glibc cvs) that
370     do not need the system call. We use the default getcwd() function via a
371     wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
372     means the current directory was removed, OR that the the system call for
373     getcwd failed (curious is that it do not fail and return NULL or set
374     errno, but rather just truncate the retured directory - usually from the
375     start), and if so, we use the generic getcwd() function (__egetcwd). Note
376     that we do not use the generic version all the time, as it calls lstat()
377     a great number of times, and performance degrade much.
378    
379     29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
380     libsandbox.c :
381     Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
382    
383     22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
384     create-localdecls :
385     When checking path names of files accessed, we need to canonicalize it, else
386     it may be a symlink in a 'write allowed' directory pointing to a file in a
387     directory we should not have write access to.
388    
389     With something like coreutils-5.0, we have two problems:
390     1) One of the tests checks if getcwd() can return a path longer than
391     PATH_MAX. This test then tries to create a dir which even while
392     created local (mkdir("conftest2")), it ends up being resolved with
393     a name that is much larger than PATH_MAX. The problem now is that
394     canonicalize() have undefined behaviour when the path was too long
395     (returned wrongly truncated paths, etc), and pass the wrong path to
396     before_syscall() (causing the bogus sandbox violations).
397     2) The ecanonicalize() function we used, along with the canonicalize()
398     function did not support longer than PATH_MAX. This is partly a
399     cause for 1), but the error checking (rather lack of it) of calls
400     to erealpath() in canonicalize() was the prime reason for 1).
401    
402     As we do not use this canonicalized name to call the function, we resolve this
403     by fixing canonicalize() to do better error checking, and ecanonicalize() as
404     well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
405     While they will resolve paths properly now, and can check if a write/read is
406     allowed, the functions called from the sandboxed environment will still work
407     as expected.
408    
409     This should resolve bug #21766.
410    
411     06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
412     For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
413     it (bug #16298).
414    
415     Problem is that for some reason locale fopen's locale.alias with mode "rm".
416    
417     -------------------------------------------------------
418     nosferatu root # grep fopen locale.log
419     fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
420     nosferatu root #
421     --------------------------------------------------------
422    
423     I checked the source of locale, but it have fopen with mode 'r', so
424     not sure where the "rm" mode comes from. Anyhow, changed the check in
425     before_syscall_open_char() to also see mode "rm" as readonly.
426    
427     23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
428    
429     Add glibc-2.3 support.
430    
431     22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
432    
433     Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
434     operations releated to preload, as well as only try to modify ld.so.preload
435     if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
436     not using ld.so.preload. Fix to not write this instance of sandbox's pid
437     to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
438    
439     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
440    
441     Changed the LD to CC for hppa.
442    
443     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
444    
445     Killed the previous changes I made.
446    
447     17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
448    
449     Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
450    
451     09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
452    
453     Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
454    
455     16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
456    
457     Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
458     for this fix.
459    
460     4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
461    
462     sandbox_futils defined a dirname() function that was masking the same
463     function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
464     '/usr/lib/portage/bi/'). Fixed function to return expected results and
465     renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
466     11231.
467    
468     4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
469    
470     Fix a segfault in libsandbox.c if canonicalize() was called with
471     first parameter = NULL.
472    
473     1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
474    
475     Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
476     cleanup() for this.
477    
478     Change cleanup() in sandbox.c not to exit with fail status if
479     the pidsfile is missing. We really should still display sandbox
480     violations if they occured.
481    
482     31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
483    
484     Update cleanup() in sandbox.c to remove the PIDSFILE if this is
485     the last sandbox running.
486    
487     25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
488    
489     Major cleanups to mainly libsandbox.c again.
490    
491     22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
492    
493     Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
494     parties involved should please contact me so that we can fix it.
495    
496     Add opendir wrapper to libsandbox.c.
497    
498     21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
499    
500     Do some more cleanups to ecanonicalize(), as it dropped filenames in
501     rare cases (after my symlink cleanups), and caused glibc to bork.
502     These fixes went into canonicalize.c.
503    
504     20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
505    
506     Fix spawn_shell() and main() in sandbox.c to properly return fail
507     status.
508    
509     19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
510    
511     The new canonicalize() function in libsandbox.c also resolved symlinks,
512     which caused on cleaning sandbox errors if the symlink pointed to a
513     file in the live root. Ripped out canonicalize() and realpath() from
514     glibc; removed the symlink stuff, and changed them to ecanonicalize()
515     and erealpath().
516    
517     18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
518    
519     Ripped out all the wrappers, and implemented those of InstallWatch.
520     Losts of cleanups and bugfixes. Implement a execve that forces
521     $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
522     /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
523     sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
524     parts; it now have an install target.
525    
526     Reformat the whole thing to look somewhat like the reworked sandbox.c
527     and new sandbox.h and sandbox_futils.c from:
528    
529     Brad House <brad@mainstreetsoftworks.com>.
