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