5 azarah 176 * sandbox-1.2.14 (2005/11/28)
6    
7 azarah 173 28 Nov 2005 Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
8 azarah 174 sandbox.c, sandbox.h, sandbox.bashrc:
9 azarah 172
10     Check generic getcwd()'s return as well for validity, bug #101728.
11    
12 azarah 173 Cleanup environ variables.
13    
14 azarah 174 Rather check SANDBOX_ACTIVE if we are already running. Set SANDBOX_ACTIVE
15     to readonly in sandbox.bashrc.
16    
17 azarah 175 Make sure we use our bashrc.
18    
19 azarah 170 01 Nov 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
20    
21     Do not pass mode to true_open and true_open64 if not needed. Should fix a
22     segfault in some cases.
23    
24 azarah 169 * sandbox-1.2.13 (2005/09/12)
25 azarah 167
26 azarah 166 12 Sep 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, libsandbox.c:
27 azarah 165
28     Do not handle adding working directory to SANDBOX_WRITE, as portage does it
29     itself.
30    
31 azarah 166 Make libsb_fini() do cleanup a bit more complete just in case we get another
32     uClibc 'call preloaded library fini before that of app' issue ... probably
33     will not help much, but we try.
34    
35 azarah 164 04 Sep 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
36    
37     Also allow symlink() system call to operate on a symlink in a writable path
38     that points to non-writable path, bug #104711.
39    
40 azarah 160 * sandbox-1.2.12 (2005/08/05)
41    
42 azarah 159 05 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
43     sandbox.h:
44 azarah 156
45     Do not give an access violation if the access() system call do not have
46     write/read access - it does not actually modify, so we only need to return
47     not being able to write/read. Noted by Andres Loeh <kosmikus@gentoo.org>,
48     bug #101433.
49    
50 azarah 157 If we are called from the command line, do not care about PORTAGE_TMPDIR,
51     and make the current directory the work directory. Also rename the variable
52     portage_tmp_dir to work_dir.
53    
54 azarah 158 Remove the tmp_dir variable - we do not need it.
55    
56 azarah 159 Improve error handling for get_sandbox_*_envvar() functions.
57    
58 azarah 153 01 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
59    
60     Still do normal log if debugging is requested.
61    
62 azarah 154 Add support for SANDBOX_VERBOSE (enabled by default). Adjust SANDBOX_DEBUG
63     to only enable if equal to "1" or "yes".
64    
65 azarah 155 Add /dev/tts to write permit, bug #42809.
66    
67 azarah 152 27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
68     sandbox_futils.c:
69    
70     Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that
71     in libsandbox .. bug #100309.
72    
73 azarah 151 22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h:
74    
75     Print all logging to stderr, bug #90343, comment #15, by Zac Medico.
76    
77 azarah 149 * sandbox-1.2.11 (2005/07/14)
78    
79 azarah 148 14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
80     Fix getcwd, bug #98419.
81    
82 azarah 145 08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c,
83     libsandbox.c:
84 azarah 146 - Try to cleanup and make error handling/printing consistent.
85     - Remove old logs if present and conflicting with current.
86 azarah 147 - Fix compile error with previous change, and return rather then exit().
87 azarah 145
88 azarah 139 07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
89     sandbox.h, sandbox_futils.c:
90     - Fix possible segfault in env init code.
91     - Major cleanup of sandbox_futils.c. Removed most of the functions as we now
92     write to /var/log/sandbox/, so in theory do not need all that.
93 azarah 140 - Redo the interface of the get_* functions so that we do not leak memory.
94 azarah 141 - Remove sandbox_dir and co - we are not using it anymore.
95 azarah 142 - Remove unused includes and variables.
96 azarah 143 - Only declare functions in sandbox_futils.c that are used in libsandbox.c when
97     OUTSIDE_LIBSANDBOX is not defined.
98 azarah 144 - Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log
99     printing's last line not honouring NOCOLOR.
100 azarah 138
101 azarah 134 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
102     libsandbox.c:
103     - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
104     write to it.
105 azarah 135 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
106 azarah 136 - Add check_prefixes() with major cleanup on check_access().
107 azarah 137 - Cleanup init_env_entries() and check_prefixes().
108 azarah 134
109 azarah 133 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
110     sandbox_futils.c, libsandbox.c:
111     Remove unused 'pids file' code.
112    
113 azarah 128 * sandbox-1.2.10 (2005/07/03)
114    
115 azarah 126 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
116     Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
117    
118 azarah 123 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
119     General cleanups:
120     - Remove fooling around with exit codes - we error out on presence of a log
121     anyhow.
122 azarah 124 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
123     appropriate there.
124 azarah 123
125 azarah 121 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
126     Cleanup the fail_nametoolong stuff a bit more.
127    
128 azarah 118 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
129 azarah 120 Remove hopefully the last ld.so.preload bits we do not use anymore.
130    
131     11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
132 azarah 119 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
133     in check_syscall(). Should speed things up a bit (at least for the getcwd()
134     and long path name test it goes down to under a second, and not 10+ seconds
135     like before). Also warn if we skip checking due to the canonicalized path
136     being too long.
137    
138     11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
139 azarah 118 More comment/readability cleanups.
140    
141 azarah 117 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
142     sandbox_futils.c, libsandbox.c:
143     Some strncpy/strncat and other cleanups.
144    
145 azarah 115 * sandbox-1.2.9 (2005/06/09)
146    
147 azarah 114 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
148     Move symlink hack down a bit to try and minimize on the amount of lstat()
149     calls we do.
150    
151 azarah 113 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
152     Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
153    
154 azarah 112 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
155     Add wrapper for access() function, bug #85413.
156    
157 azarah 111 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
158     Use generic getcwd() implementation from uclibc - should be more portable
159     and looks a bit cleaner.
160    
161 azarah 110 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
162     Make sure our true_* pointers are initialized to NULL, and that we check for
163     all references that they are valid.
164    
165 azarah 109 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
166     Be default we will fail if the path name we try to canonicalize is too long.
167     This however could cause issues with some things (bug #94630 and #21766), so
168     if fail_nametoolong == 0, canonicalize() will return a null length string and
169     do not fail.
170    
171 azarah 108 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
172     Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
173     make sure we re-export the new TMPDIR environment variable.
174    
175 azarah 106 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
176     Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
177     by Marcus D. Hanwell <cryos@gentoo.org>.
178    
179 azarah 105 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
180     Add /dev/console to write list, bug #38588.
181    
182 azarah 102 * sandbox-1.2.8 (2005/05/13)
183    
184 azarah 99 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
185 azarah 101 sandbox.h, sandbox_futils.c:
186     General cleanups.
187    
188     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
189 azarah 100 sandbox.h:
190     Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
191    
192     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
193 azarah 99 sandbox.h, sandbox_futils.c:
194     Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
195     to use TMPDIR if present in environment.
196    
197 azarah 98 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
198     Remove sandbox_log_file from main() as its no longer used.
199    
200 azarah 97 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
201     sandbox_futils.c:
202     Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
203     if already exported when sandbox started). Fix get_sandbox_log() and new
204     get_sandbox_debug_log() to not use already exported environment variables if
205     they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
206     SB_PATH_MAX fixes.
207    
208 azarah 94 * sandbox-1.2.7 (2005/05/12)
209    
210 azarah 93 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
211     sandbox_futils.c:
212     More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
213    
214 azarah 92 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
215     Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
216     with '(null)' in it if we did not call sandbox with absolute path.
217    
218 azarah 89 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
219 azarah 91 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
220     for the child.
221    
222     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
223 azarah 90 Remove global preload_adaptable as it is no longer used.
224    
225     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
226 azarah 89 Rewrite environment stuff to only be set when execve'ing the child process
227     to try and avoid issues like bug #91541 that causes sandbox to crash if
228     we set LD_PRELOAD sandbox side already.
229    
230 azarah 87 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
231 azarah 88 Move print_sandbox_log() up to make things neater.
232    
233     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
234 azarah 87 Remove load_preload_libs(), as its not used anymore.
235    
236 azarah 83 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
237 azarah 86 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
238    
239     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
240 azarah 84 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
241    
242     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
243 azarah 83 Remove ld.so.preload crap - we are not going to use it again.
244    
245 azarah 82 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
246     Fix typo in code that checks if we got valid group information, causing a
247     segmentation fault, bug #91637.
248    
249 azarah 79 * sandbox-1.2.6 (2005/05/10)
250    
251 azarah 78 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
252     Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
253     for some odd reason, bug #91541.
254    
255 azarah 77 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
256     Fix typo (sizeof -> strlen).
257    
258 ferringb 76 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
259     rewrote the sbcontext caching code so it accounts for env changes since lib
260     initialization.
261    
262 azarah 75 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
263     We create libctest.c via configure, so no need to keep it around. Do some
264     cleanup related to libctest.c and libctest during configure.
265    
266 azarah 74 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
267     Add rename support of symlinks pointing to protected files/directories.
268    
269 azarah 72 * sandbox-1.2.5 (2005/05/04)
270    
271 azarah 71 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
272     sandbox.bashrc:
273     Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
274     already set, init of the env vars fails for some reason, so do this later on,
275     and do not warn (bug #91431).
276    
277 azarah 70 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
278     sandbox.bashrc:
279     Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
280    
281 azarah 68 * sandbox-1.2.4 (2005/05/03)
282    
283 azarah 66 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
284     Do not init the env entries with each call, as it creates too many calls to
285 azarah 67 lstat, etc. Should speedup things a bit, bug #91040.
286 azarah 66
287 azarah 65 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
288     Add /dev/pty to default write list. Noticed by Morfic.
289    
290 vapier 62 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
291     sandbox.h:
292     uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
293     exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
294    
295 azarah 59 * sandbox-1.2.3 (2005/04/29)
296    
297 azarah 56 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
298     Do not check for (*&#$(* CXX or F77.
299    
300 azarah 54 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
301     Do not append '/' to pathname in filter_path() if it already ends with it.
302    
303 vapier 53 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
304     With az's help, clean up autotools to work with cross-compiling.
305    
306 azarah 59 * sandbox-1.2.2 (2005/04/28)
307 azarah 48
308 azarah 47 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
309     Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
310     have issues; bug #90592.
311    
312 azarah 59 * sandbox-1.2.1 (2005/04/23)
313 azarah 44
314 azarah 43 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
315     getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
316     Make sure all functions used in libsandbox.c is declared static. Define
317     SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
318     linking with its object. Hopefully this will fix bug #90153.
319    
320 azarah 59 * sandbox-1.2 (2005/04/23)
321 azarah 46
322 azarah 40 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
323     Allow lchown a symlink in write-allowed path pointing to write-denied
324     target.
325    
326 genone 39 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
327     Also show resolved symlink names in the log.
328    
329 azarah 37 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
330     Seems -nostdlib was the problem with the constructor/destructor - remove it
331     from Makefile.am, and change the constructor/destructor names again.
332    
333 azarah 36 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
334     Also rename the _init() and _fini() declarations.
335    
336 azarah 35 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
337     Fixup the constructor/destructor function names again (they should be _init()
338     and _fini() it seems, and not being called caused sandbox_lib_path to be
339     unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
340     Add both the path in given SANDBOX_x variable, as well as its symlink
341     resolved path in init_env_entries(). Modify filter_path() to be able to
342     resolve paths without resolving symlinks, as well as to be able to resolve
343     symlinks. Fix a possible segfault in check_access(). Add symlink resolving
344     to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
345     for bug #31019 cause access violations if we try to remove a symlink that is
346     not in protected path, but points to a protected path. Fix a memory leak in
347     sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
348     (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
349     (pid_string was uninitialized). General syntax cleanups.
350    
351 ferringb 34 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
352     infamous "pids file is not a regular file" w/out newline bug.
353    
354 ferringb 33 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
355     Correct libc_version path detection, since it was screwing up if libdir !=
356     "/lib/".
357    
358     02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
359 azarah 32 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
360    
361 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
362 azarah 31 Fix symbols.in not added to dist.
363    
364 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
365 azarah 30 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
366     White space fixes.
367    
368 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
369 azarah 30 configure.in, getcwd.c, libsandbox.c, symbols.in:
370 azarah 29 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
371     getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
372     for glibc and other libc's that use this. Update libsandbox.c to use these
373     symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
374     process unset it.
375    
376 ferringb 33 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
377 ferringb 28 killed off _init and _fini in favor of
378     void __attribute__ ((constructor)) init_func and
379     void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
380    
381 ferringb 26 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
382     canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
383     having the hick-ups.
384    
385 ferringb 24 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
386     Makefile.am: Fixed compilation.
387    
388 ferringb 18 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
389     Gutted the bugger so it stops checking for a c++ and fortran compiler.
390     Do *not* regenerate aclocal.m4 for making a release until a better
391     solution is created.
392    
393 ferringb 16 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
394     Removal of more hardcoded paths.
395    
396 ferringb 13 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
397     sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
398    
399     19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
400 ferringb 6 Sandbox is now autotooled, create-localdecls needs to be killed and the code
401     shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
402     are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
403     To get to a point of testing, automake && autoconf; created requisite files w/
404     a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
405     /lib and /usr/lib/portage/bin.
406    
407 ferringb 2 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
408     closing out bug #70225, potential overflow of the sandbox_pids_file var.
409    
410     07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
411     (think it was at least) allows intermixing of code and data segments. bug #70351
412     should be fixed by this.
413    
414     03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
415     futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
416    
417     02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
418     Seth Robertson that tracked down all adjuct flags for read operations that
419     do not invoke a write operation.
420    
421     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
422     Another fix from jstubbs regarding a free() on a stack variable for the
423     environment -- tracking now prevents extraneous free()'s segfault.
424    
425     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
426     J. Stubbs tracked down a new bug where mkdir was failing to the patch on
427     the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
428     Also remove the errno = ESUCCESS settings as documentation points out that
429     a library isn't allowed to do that.
430    
431     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
432     file_security_check() function to check random potential exploits on files
433     that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
434     the 'system-crippling' exploits (bug 21923) and catches a few other
435     potential problems.
436    
437     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
438     32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
439    
440     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
441     bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
442     Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
443    
444     29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
445     Fix permissions and group of pids file and logs. Permissions should be 0664
446     and group should be 'portage'. Bug #34260.
447    
448     28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
449     Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
450     to the real execve (in our execve wrapper). Seems that on some arches (sparc
451     among others) do not allow us to tamper with the readonly copy passed to
452     execve, so pass our own copy of the environment. Bug #42290.
453    
454     11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
455     Changed tail to head and added a notice about duration of glibc check.
456    
457     21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
458     Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
459     as there isn't a guarentee that it is dynamic.
460    
461     02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
462     If 'file' passed to before_syscall(const char *func, const char *file) is
463     invalid, we should set errno to ENOENT, and not EINVAL. This should
464     close bug #32238.
465    
466     14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
467     Fix a bug that occurs mainly on 64bit arch, where the file passed to
468     the functions we wrap, is invalid, and then cause canonicalize to pass
469     garbage to before_syscall(), thanks to great detective work from
470     Andrea Luzzardi <al@sig11.org> (bug #29846).
471    
472     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
473     Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
474    
475     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
476     Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
477     only checked the destination patch, and not the source, so we could move
478     a protected file to a unprotected directory, and then delete/modify it.
479     Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
480    
481     12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
482     Added python2.3 to the predict section/variable.
483    
484     28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
485     sandbox.h, sandbox_futils.c :
486     Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
487     it is not set, it will revert to its old value.
488    
489     27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
490     Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
491     rather than failing with a violation, bug #29748.
492    
493     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
494     Fix canonicalize() to ignore calls with path = "".
495    
496     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
497     sandbox_futils.c, canonicalize.c :
498     Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
499     call handled strings larger than PATH_MAX (bug #21766). It however does not
500     work the same on 2.4 kernels.
501    
502     To fix, I added the posix implementation of getcwd() (from glibc cvs) that
503     do not need the system call. We use the default getcwd() function via a
504     wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
505     means the current directory was removed, OR that the the system call for
506     getcwd failed (curious is that it do not fail and return NULL or set
507     errno, but rather just truncate the retured directory - usually from the
508     start), and if so, we use the generic getcwd() function (__egetcwd). Note
509     that we do not use the generic version all the time, as it calls lstat()
510     a great number of times, and performance degrade much.
511    
512     29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
513     libsandbox.c :
514     Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
515    
516     22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
517     create-localdecls :
518     When checking path names of files accessed, we need to canonicalize it, else
519     it may be a symlink in a 'write allowed' directory pointing to a file in a
520     directory we should not have write access to.
521    
522     With something like coreutils-5.0, we have two problems:
523     1) One of the tests checks if getcwd() can return a path longer than
524     PATH_MAX. This test then tries to create a dir which even while
525     created local (mkdir("conftest2")), it ends up being resolved with
526     a name that is much larger than PATH_MAX. The problem now is that
527     canonicalize() have undefined behaviour when the path was too long
528     (returned wrongly truncated paths, etc), and pass the wrong path to
529     before_syscall() (causing the bogus sandbox violations).
530     2) The ecanonicalize() function we used, along with the canonicalize()
531     function did not support longer than PATH_MAX. This is partly a
532     cause for 1), but the error checking (rather lack of it) of calls
533     to erealpath() in canonicalize() was the prime reason for 1).
534    
535     As we do not use this canonicalized name to call the function, we resolve this
536     by fixing canonicalize() to do better error checking, and ecanonicalize() as
537     well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
538     While they will resolve paths properly now, and can check if a write/read is
539     allowed, the functions called from the sandboxed environment will still work
540     as expected.
541    
542     This should resolve bug #21766.
543    
544     06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
545     For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
546     it (bug #16298).
547    
548     Problem is that for some reason locale fopen's locale.alias with mode "rm".
549    
550     -------------------------------------------------------
551     nosferatu root # grep fopen locale.log
552     fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
553     nosferatu root #
554     --------------------------------------------------------
555    
556     I checked the source of locale, but it have fopen with mode 'r', so
557     not sure where the "rm" mode comes from. Anyhow, changed the check in
558     before_syscall_open_char() to also see mode "rm" as readonly.
559    
560     23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
561    
562     Add glibc-2.3 support.
563    
564     22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
565    
566     Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
567     operations releated to preload, as well as only try to modify ld.so.preload
568     if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
569     not using ld.so.preload. Fix to not write this instance of sandbox's pid
570     to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
571    
572     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
573    
574     Changed the LD to CC for hppa.
575    
576     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
577    
578     Killed the previous changes I made.
579    
580     17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
581    
582     Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
583    
584     09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
585    
586     Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
587    
588     16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
589    
590     Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
591     for this fix.
592    
593     4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
594    
595     sandbox_futils defined a dirname() function that was masking the same
596     function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
597     '/usr/lib/portage/bi/'). Fixed function to return expected results and
598     renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
599     11231.
600    
601     4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
602    
603     Fix a segfault in libsandbox.c if canonicalize() was called with
604     first parameter = NULL.
605    
606     1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
607    
608     Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
609     cleanup() for this.
610    
611     Change cleanup() in sandbox.c not to exit with fail status if
612     the pidsfile is missing. We really should still display sandbox
613     violations if they occured.
614    
615     31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
616    
617     Update cleanup() in sandbox.c to remove the PIDSFILE if this is
618     the last sandbox running.
619    
620     25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
621    
622     Major cleanups to mainly libsandbox.c again.
623    
624     22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
625    
626     Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
627     parties involved should please contact me so that we can fix it.
628    
629     Add opendir wrapper to libsandbox.c.
630    
631     21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
632    
633     Do some more cleanups to ecanonicalize(), as it dropped filenames in
634     rare cases (after my symlink cleanups), and caused glibc to bork.
635     These fixes went into canonicalize.c.
636    
637     20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
638    
639     Fix spawn_shell() and main() in sandbox.c to properly return fail
640     status.
641    
642     19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
643    
644     The new canonicalize() function in libsandbox.c also resolved symlinks,
645     which caused on cleaning sandbox errors if the symlink pointed to a
646     file in the live root. Ripped out canonicalize() and realpath() from
647     glibc; removed the symlink stuff, and changed them to ecanonicalize()
648     and erealpath().
649    
650     18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
651    
652     Ripped out all the wrappers, and implemented those of InstallWatch.
653     Losts of cleanups and bugfixes. Implement a execve that forces
654     $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
655     /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
656     sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
657     parts; it now have an install target.
658    
659     Reformat the whole thing to look somewhat like the reworked sandbox.c
660     and new sandbox.h and sandbox_futils.c from:
661    
662     Brad House <brad@mainstreetsoftworks.com>.
