4    
5 ferringb 18 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
6     Gutted the bugger so it stops checking for a c++ and fortran compiler.
7     Do *not* regenerate aclocal.m4 for making a release until a better
8     solution is created.
9    
10 ferringb 16 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
11     Removal of more hardcoded paths.
12    
13 ferringb 13 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
14     sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
15    
16     19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
17 ferringb 6 Sandbox is now autotooled, create-localdecls needs to be killed and the code
18     shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
19     are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
20     To get to a point of testing, automake && autoconf; created requisite files w/
21     a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
22     /lib and /usr/lib/portage/bin.
23    
24 ferringb 2 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
25     closing out bug #70225, potential overflow of the sandbox_pids_file var.
26    
27     07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
28     (think it was at least) allows intermixing of code and data segments. bug #70351
29     should be fixed by this.
30    
31     03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
32     futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
33    
34     02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
35     Seth Robertson that tracked down all adjuct flags for read operations that
36     do not invoke a write operation.
37    
38     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
39     Another fix from jstubbs regarding a free() on a stack variable for the
40     environment -- tracking now prevents extraneous free()'s segfault.
41    
42     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
43     J. Stubbs tracked down a new bug where mkdir was failing to the patch on
44     the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
45     Also remove the errno = ESUCCESS settings as documentation points out that
46     a library isn't allowed to do that.
47    
48     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
49     file_security_check() function to check random potential exploits on files
50     that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
51     the 'system-crippling' exploits (bug 21923) and catches a few other
52     potential problems.
53    
54     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
55     32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
56    
57     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
58     bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
59     Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
60    
61     29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
62     Fix permissions and group of pids file and logs. Permissions should be 0664
63     and group should be 'portage'. Bug #34260.
64    
65     28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
66     Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
67     to the real execve (in our execve wrapper). Seems that on some arches (sparc
68     among others) do not allow us to tamper with the readonly copy passed to
69     execve, so pass our own copy of the environment. Bug #42290.
70    
71     11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
72     Changed tail to head and added a notice about duration of glibc check.
73    
74     21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
75     Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
76     as there isn't a guarentee that it is dynamic.
77    
78     02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
79     If 'file' passed to before_syscall(const char *func, const char *file) is
80     invalid, we should set errno to ENOENT, and not EINVAL. This should
81     close bug #32238.
82    
83     14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
84     Fix a bug that occurs mainly on 64bit arch, where the file passed to
85     the functions we wrap, is invalid, and then cause canonicalize to pass
86     garbage to before_syscall(), thanks to great detective work from
87     Andrea Luzzardi <al@sig11.org> (bug #29846).
88    
89     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
90     Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
91    
92     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
93     Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
94     only checked the destination patch, and not the source, so we could move
95     a protected file to a unprotected directory, and then delete/modify it.
96     Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
97    
98     12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
99     Added python2.3 to the predict section/variable.
100    
101     28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
102     sandbox.h, sandbox_futils.c :
103     Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
104     it is not set, it will revert to its old value.
105    
106     27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
107     Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
108     rather than failing with a violation, bug #29748.
109    
110     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
111     Fix canonicalize() to ignore calls with path = "".
112    
113     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
114     sandbox_futils.c, canonicalize.c :
115     Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
116     call handled strings larger than PATH_MAX (bug #21766). It however does not
117     work the same on 2.4 kernels.
118    
119     To fix, I added the posix implementation of getcwd() (from glibc cvs) that
120     do not need the system call. We use the default getcwd() function via a
121     wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
122     means the current directory was removed, OR that the the system call for
123     getcwd failed (curious is that it do not fail and return NULL or set
124     errno, but rather just truncate the retured directory - usually from the
125     start), and if so, we use the generic getcwd() function (__egetcwd). Note
126     that we do not use the generic version all the time, as it calls lstat()
127     a great number of times, and performance degrade much.
128    
129     29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
130     libsandbox.c :
131     Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
132    
133     22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
134     create-localdecls :
135     When checking path names of files accessed, we need to canonicalize it, else
136     it may be a symlink in a 'write allowed' directory pointing to a file in a
137     directory we should not have write access to.
138    
139     With something like coreutils-5.0, we have two problems:
140     1) One of the tests checks if getcwd() can return a path longer than
141     PATH_MAX. This test then tries to create a dir which even while
142     created local (mkdir("conftest2")), it ends up being resolved with
143     a name that is much larger than PATH_MAX. The problem now is that
144     canonicalize() have undefined behaviour when the path was too long
145     (returned wrongly truncated paths, etc), and pass the wrong path to
146     before_syscall() (causing the bogus sandbox violations).
147     2) The ecanonicalize() function we used, along with the canonicalize()
148     function did not support longer than PATH_MAX. This is partly a
149     cause for 1), but the error checking (rather lack of it) of calls
150     to erealpath() in canonicalize() was the prime reason for 1).
151    
152     As we do not use this canonicalized name to call the function, we resolve this
153     by fixing canonicalize() to do better error checking, and ecanonicalize() as
154     well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
155     While they will resolve paths properly now, and can check if a write/read is
156     allowed, the functions called from the sandboxed environment will still work
157     as expected.
158    
159     This should resolve bug #21766.
160    
161     06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
162     For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
163     it (bug #16298).
164    
165     Problem is that for some reason locale fopen's locale.alias with mode "rm".
166    
167     -------------------------------------------------------
168     nosferatu root # grep fopen locale.log
169     fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
170     nosferatu root #
171     --------------------------------------------------------
172    
173     I checked the source of locale, but it have fopen with mode 'r', so
174     not sure where the "rm" mode comes from. Anyhow, changed the check in
175     before_syscall_open_char() to also see mode "rm" as readonly.
176    
177     23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
178    
179     Add glibc-2.3 support.
180    
181     22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
182    
183     Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
184     operations releated to preload, as well as only try to modify ld.so.preload
185     if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
186     not using ld.so.preload. Fix to not write this instance of sandbox's pid
187     to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
188    
189     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
190    
191     Changed the LD to CC for hppa.
192    
193     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
194    
195     Killed the previous changes I made.
196    
197     17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
198    
199     Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
200    
201     09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
202    
203     Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
204    
205     16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
206    
207     Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
208     for this fix.
209    
210     4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
211    
212     sandbox_futils defined a dirname() function that was masking the same
213     function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
214     '/usr/lib/portage/bi/'). Fixed function to return expected results and
215     renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
216     11231.
217    
218     4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
219    
220     Fix a segfault in libsandbox.c if canonicalize() was called with
221     first parameter = NULL.
222    
223     1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
224    
225     Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
226     cleanup() for this.
227    
228     Change cleanup() in sandbox.c not to exit with fail status if
229     the pidsfile is missing. We really should still display sandbox
230     violations if they occured.
231    
232     31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
233    
234     Update cleanup() in sandbox.c to remove the PIDSFILE if this is
235     the last sandbox running.
236    
237     25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
238    
239     Major cleanups to mainly libsandbox.c again.
240    
241     22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
242    
243     Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
244     parties involved should please contact me so that we can fix it.
245    
246     Add opendir wrapper to libsandbox.c.
247    
248     21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
249    
250     Do some more cleanups to ecanonicalize(), as it dropped filenames in
251     rare cases (after my symlink cleanups), and caused glibc to bork.
252     These fixes went into canonicalize.c.
253    
254     20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
255    
256     Fix spawn_shell() and main() in sandbox.c to properly return fail
257     status.
258    
259     19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
260    
261     The new canonicalize() function in libsandbox.c also resolved symlinks,
262     which caused on cleaning sandbox errors if the symlink pointed to a
263     file in the live root. Ripped out canonicalize() and realpath() from
264     glibc; removed the symlink stuff, and changed them to ecanonicalize()
265     and erealpath().
266    
267     18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
268    
269     Ripped out all the wrappers, and implemented those of InstallWatch.
270     Losts of cleanups and bugfixes. Implement a execve that forces
271     $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
272     /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
273     sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
274     parts; it now have an install target.
275    
276     Reformat the whole thing to look somewhat like the reworked sandbox.c
277     and new sandbox.h and sandbox_futils.c from:
278    
279     Brad House <brad@mainstreetsoftworks.com>.
280    
281     Additional Copyrights now due to the InstallWatch code:
