5 01 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
6 killed off _init and _fini in favor of
7 void __attribute__ ((constructor)) init_func and
8 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
9
10 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
11 canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
12 having the hick-ups.
13
14 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
15 Makefile.am: Fixed compilation.
16
17 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
18 Gutted the bugger so it stops checking for a c++ and fortran compiler.
19 Do *not* regenerate aclocal.m4 for making a release until a better
20 solution is created.
21
22 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
23 Removal of more hardcoded paths.
24
25 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
26 sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
27
28 19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
29 Sandbox is now autotooled, create-localdecls needs to be killed and the code
30 shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
31 are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
32 To get to a point of testing, automake && autoconf; created requisite files w/
33 a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
34 /lib and /usr/lib/portage/bin.
35
36 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
37 closing out bug #70225, potential overflow of the sandbox_pids_file var.
38
39 07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
40 (think it was at least) allows intermixing of code and data segments. bug #70351
41 should be fixed by this.
42
43 03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
44 futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
45
46 02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
47 Seth Robertson that tracked down all adjuct flags for read operations that
48 do not invoke a write operation.
49
50 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
51 Another fix from jstubbs regarding a free() on a stack variable for the
52 environment -- tracking now prevents extraneous free()'s segfault.
53
54 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
55 J. Stubbs tracked down a new bug where mkdir was failing to the patch on
56 the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
57 Also remove the errno = ESUCCESS settings as documentation points out that
58 a library isn't allowed to do that.
59
60 04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
61 file_security_check() function to check random potential exploits on files
62 that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
63 the 'system-crippling' exploits (bug 21923) and catches a few other
64 potential problems.
65
66 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
67 32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
68
69 20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
70 bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
71 Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
72
73 29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
74 Fix permissions and group of pids file and logs. Permissions should be 0664
75 and group should be 'portage'. Bug #34260.
76
77 28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
78 Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
79 to the real execve (in our execve wrapper). Seems that on some arches (sparc
80 among others) do not allow us to tamper with the readonly copy passed to
81 execve, so pass our own copy of the environment. Bug #42290.
82
83 11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
84 Changed tail to head and added a notice about duration of glibc check.
85
86 21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
87 Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
88 as there isn't a guarentee that it is dynamic.
89
90 02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
91 If 'file' passed to before_syscall(const char *func, const char *file) is
92 invalid, we should set errno to ENOENT, and not EINVAL. This should
93 close bug #32238.
94
95 14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
96 Fix a bug that occurs mainly on 64bit arch, where the file passed to
97 the functions we wrap, is invalid, and then cause canonicalize to pass
98 garbage to before_syscall(), thanks to great detective work from
99 Andrea Luzzardi <al@sig11.org> (bug #29846).
100
101 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
102 Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
103
104 13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
105 Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
106 only checked the destination patch, and not the source, so we could move
107 a protected file to a unprotected directory, and then delete/modify it.
108 Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
109
110 12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
111 Added python2.3 to the predict section/variable.
112
113 28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
114 sandbox.h, sandbox_futils.c :
115 Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
116 it is not set, it will revert to its old value.
117
118 27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
119 Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
120 rather than failing with a violation, bug #29748.
121
122 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
123 Fix canonicalize() to ignore calls with path = "".
124
125 27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
126 sandbox_futils.c, canonicalize.c :
127 Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
128 call handled strings larger than PATH_MAX (bug #21766). It however does not
129 work the same on 2.4 kernels.
130
131 To fix, I added the posix implementation of getcwd() (from glibc cvs) that
132 do not need the system call. We use the default getcwd() function via a
133 wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
134 means the current directory was removed, OR that the the system call for
135 getcwd failed (curious is that it do not fail and return NULL or set
136 errno, but rather just truncate the retured directory - usually from the
137 start), and if so, we use the generic getcwd() function (__egetcwd). Note
138 that we do not use the generic version all the time, as it calls lstat()
139 a great number of times, and performance degrade much.
140
141 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
142 libsandbox.c :
143 Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
144
145 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
146 create-localdecls :
147 When checking path names of files accessed, we need to canonicalize it, else
148 it may be a symlink in a 'write allowed' directory pointing to a file in a
149 directory we should not have write access to.
150
151 With something like coreutils-5.0, we have two problems:
152 1) One of the tests checks if getcwd() can return a path longer than
153 PATH_MAX. This test then tries to create a dir which even while
154 created local (mkdir("conftest2")), it ends up being resolved with
155 a name that is much larger than PATH_MAX. The problem now is that
156 canonicalize() have undefined behaviour when the path was too long
157 (returned wrongly truncated paths, etc), and pass the wrong path to
158 before_syscall() (causing the bogus sandbox violations).
159 2) The ecanonicalize() function we used, along with the canonicalize()
160 function did not support longer than PATH_MAX. This is partly a
161 cause for 1), but the error checking (rather lack of it) of calls
162 to erealpath() in canonicalize() was the prime reason for 1).
163
164 As we do not use this canonicalized name to call the function, we resolve this
165 by fixing canonicalize() to do better error checking, and ecanonicalize() as
166 well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
167 While they will resolve paths properly now, and can check if a write/read is
168 allowed, the functions called from the sandboxed environment will still work
169 as expected.
170
171 This should resolve bug #21766.
172
173 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
174 For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
175 it (bug #16298).
176
177 Problem is that for some reason locale fopen's locale.alias with mode "rm".
178
179 -------------------------------------------------------
180 nosferatu root # grep fopen locale.log
181 fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
182 nosferatu root #
183 --------------------------------------------------------
184
185 I checked the source of locale, but it have fopen with mode 'r', so
186 not sure where the "rm" mode comes from. Anyhow, changed the check in
187 before_syscall_open_char() to also see mode "rm" as readonly.
188
189 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
190
191 Add glibc-2.3 support.
192
193 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
194
195 Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
196 operations releated to preload, as well as only try to modify ld.so.preload
197 if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
198 not using ld.so.preload. Fix to not write this instance of sandbox's pid
199 to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
200
201 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
202
203 Changed the LD to CC for hppa.
204
205 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
206
207 Killed the previous changes I made.
208
209 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
210
211 Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
212
213 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
214
215 Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
216
217 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
218
219 Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
220 for this fix.
221
222 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
223
224 sandbox_futils defined a dirname() function that was masking the same
225 function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
226 '/usr/lib/portage/bi/'). Fixed function to return expected results and
227 renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
228 11231.
229
230 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
231
232 Fix a segfault in libsandbox.c if canonicalize() was called with
233 first parameter = NULL.
234
235 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
236
237 Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
238 cleanup() for this.
239
240 Change cleanup() in sandbox.c not to exit with fail status if
241 the pidsfile is missing. We really should still display sandbox
242 violations if they occured.
243
244 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
245
246 Update cleanup() in sandbox.c to remove the PIDSFILE if this is
247 the last sandbox running.
248
249 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
250
251 Major cleanups to mainly libsandbox.c again.
252
253 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
254
255 Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
256 parties involved should please contact me so that we can fix it.
257
258 Add opendir wrapper to libsandbox.c.
259
260 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
261
262 Do some more cleanups to ecanonicalize(), as it dropped filenames in
263 rare cases (after my symlink cleanups), and caused glibc to bork.
264 These fixes went into canonicalize.c.
265
266 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
267
268 Fix spawn_shell() and main() in sandbox.c to properly return fail
269 status.
270
271 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
272
273 The new canonicalize() function in libsandbox.c also resolved symlinks,
274 which caused on cleaning sandbox errors if the symlink pointed to a
275 file in the live root. Ripped out canonicalize() and realpath() from
276 glibc; removed the symlink stuff, and changed them to ecanonicalize()
277 and erealpath().
278
279 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
280
281 Ripped out all the wrappers, and implemented those of InstallWatch.
282 Losts of cleanups and bugfixes. Implement a execve that forces
283 $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
284 /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
285 sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
286 parts; it now have an install target.
287
288 Reformat the whole thing to look somewhat like the reworked sandbox.c
289 and new sandbox.h and sandbox_futils.c from:
290
291 Brad House <brad@mainstreetsoftworks.com>.
292
293 Additional Copyrights now due to the InstallWatch code:
