4 azarah 183 01 Dec 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, Makefile.am,
5     localdecls.h, scripts/Makefile.am, scripts/gen_symbol_version_map.awk,
6     scripts/gen_symbol_header.awk, src/Makefile.am, src/symbols.in,
7 azarah 184 src/libsandbox.c, src/getcwd.c, src/sandbox.c, data/sandbox.bashrc:
8 azarah 183
9     Use versioned symbols on supported libc's for functions we wrap, as well as
10     provide all versions of specific functions. Some syntax cleanups.
11    
12 azarah 184 Only check SANDBOX_ACTIVE, and not its value. More BASH_ENV fixes.
13    
14 azarah 186 Rename configure.in to configure.ac.
15    
16 azarah 187 Fix non-versioned libc's to also prepend '__' to internal symbols by using
17     strong aliases.
18    
19 azarah 189 Remove the SB_STATIC and including of getcwd.c, etc voodoo, as we new use a
20     symbol map, and all non-exported symbols are local. Cleanup getcwd.c, as
21     the generic getcwd for older 2.4 kernels do not work properly anyhow, and
22     just makes things slower. Some other warning fixes.
23    
24 azarah 190 Rename src/symbols.in to src/symbols.h.in.
25    
26 azarah 191 Cleanup local defines for egetcwd() and erealpath().
27    
28 azarah 192 Rename filter_path() to resolve_path() and other renames for clarity.
29    
30 azarah 193 Fixup SANDBOX_ON handling after already running changes.
31    
32 azarah 194 Use egetcwd() in sandbox.c.
33    
34 azarah 195 Rather use fstat() to get file size in file_length() than lseek().
35    
36 azarah 196 Wrap mknod() as well. Misc cleanups.
37    
38 azarah 197 Wrap mkfifo() as it seems it was missing.
39    
40 azarah 183 28 Nov 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, sandbox.c,
41 azarah 181 sandbox_fdutils.c:
42 azarah 179
43     Detect if we on 64bit arch automatically.
44    
45 azarah 180 Update contact email. Fix quoting.
46    
47 azarah 181 Revert 64bit arch test, as we should build the 32bit version without full
48     path checking as well, and add --enable-multilib switch to configure.
49    
50 azarah 176 * sandbox-1.2.14 (2005/11/28)
51    
52 azarah 183 28 Nov 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
53 azarah 174 sandbox.c, sandbox.h, sandbox.bashrc:
54 azarah 172
55     Check generic getcwd()'s return as well for validity, bug #101728.
56    
57 azarah 173 Cleanup environ variables.
58    
59 azarah 174 Rather check SANDBOX_ACTIVE if we are already running. Set SANDBOX_ACTIVE
60     to readonly in sandbox.bashrc.
61    
62 azarah 175 Make sure we use our bashrc.
63    
64 azarah 170 01 Nov 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
65    
66     Do not pass mode to true_open and true_open64 if not needed. Should fix a
67     segfault in some cases.
68    
69 azarah 169 * sandbox-1.2.13 (2005/09/12)
70 azarah 167
71 azarah 166 12 Sep 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, libsandbox.c:
72 azarah 165
73     Do not handle adding working directory to SANDBOX_WRITE, as portage does it
74     itself.
75    
76 azarah 166 Make libsb_fini() do cleanup a bit more complete just in case we get another
77     uClibc 'call preloaded library fini before that of app' issue ... probably
78     will not help much, but we try.
79    
80 azarah 164 04 Sep 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
81    
82     Also allow symlink() system call to operate on a symlink in a writable path
83     that points to non-writable path, bug #104711.
84    
85 azarah 160 * sandbox-1.2.12 (2005/08/05)
86    
87 azarah 159 05 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
88     sandbox.h:
89 azarah 156
90     Do not give an access violation if the access() system call do not have
91     write/read access - it does not actually modify, so we only need to return
92     not being able to write/read. Noted by Andres Loeh <kosmikus@gentoo.org>,
93     bug #101433.
94    
95 azarah 157 If we are called from the command line, do not care about PORTAGE_TMPDIR,
96     and make the current directory the work directory. Also rename the variable
97     portage_tmp_dir to work_dir.
98    
99 azarah 158 Remove the tmp_dir variable - we do not need it.
100    
101 azarah 159 Improve error handling for get_sandbox_*_envvar() functions.
102    
103 azarah 153 01 Aug 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
104    
105     Still do normal log if debugging is requested.
106    
107 azarah 154 Add support for SANDBOX_VERBOSE (enabled by default). Adjust SANDBOX_DEBUG
108     to only enable if equal to "1" or "yes".
109    
110 azarah 155 Add /dev/tts to write permit, bug #42809.
111    
112 azarah 152 27 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
113     sandbox_futils.c:
114    
115     Do not resolve symlinks in PORTAGE_TMPDIR in sandbox .. we will handle that
116     in libsandbox .. bug #100309.
117    
118 azarah 151 22 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h:
119    
120     Print all logging to stderr, bug #90343, comment #15, by Zac Medico.
121    
122 azarah 149 * sandbox-1.2.11 (2005/07/14)
123    
124 azarah 148 14 July 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
125     Fix getcwd, bug #98419.
126    
127 azarah 145 08 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c,
128     libsandbox.c:
129 azarah 146 - Try to cleanup and make error handling/printing consistent.
130     - Remove old logs if present and conflicting with current.
131 azarah 147 - Fix compile error with previous change, and return rather then exit().
132 azarah 145
133 azarah 139 07 July 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
134     sandbox.h, sandbox_futils.c:
135     - Fix possible segfault in env init code.
136     - Major cleanup of sandbox_futils.c. Removed most of the functions as we now
137     write to /var/log/sandbox/, so in theory do not need all that.
138 azarah 140 - Redo the interface of the get_* functions so that we do not leak memory.
139 azarah 141 - Remove sandbox_dir and co - we are not using it anymore.
140 azarah 142 - Remove unused includes and variables.
141 azarah 143 - Only declare functions in sandbox_futils.c that are used in libsandbox.c when
142     OUTSIDE_LIBSANDBOX is not defined.
143 azarah 144 - Cleanup access/log printing. Make access printing honour NOCOLOR. Fix log
144     printing's last line not honouring NOCOLOR.
145 azarah 138
146 azarah 134 06 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.h, sandbox_futils.c,
147     libsandbox.c:
148     - Change log dir to /var/log/sandbox/. Make sure the sandboxed process cannot
149     write to it.
150 azarah 135 - Clean up logging in libsandbox.c, and hopefully make it more consistant.
151 azarah 136 - Add check_prefixes() with major cleanup on check_access().
152 azarah 137 - Cleanup init_env_entries() and check_prefixes().
153 azarah 134
154 azarah 133 05 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
155     sandbox_futils.c, libsandbox.c:
156     Remove unused 'pids file' code.
157    
158 azarah 128 * sandbox-1.2.10 (2005/07/03)
159    
160 azarah 126 03 July 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
161     Add PREDICT items for nss-db, bug #92079. Patch from Robin Johnson.
162    
163 azarah 123 17 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
164     General cleanups:
165     - Remove fooling around with exit codes - we error out on presence of a log
166     anyhow.
167 azarah 124 - Move get_sandbox_*_envvar() to sandbox_setup_environ(), as its more
168     appropriate there.
169 azarah 123
170 azarah 121 12 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
171     Cleanup the fail_nametoolong stuff a bit more.
172    
173 azarah 118 11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
174 azarah 120 Remove hopefully the last ld.so.preload bits we do not use anymore.
175    
176     11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
177 azarah 119 Remove the unneeded canonicalize() calls in the wrappers - we do it anyhow
178     in check_syscall(). Should speed things up a bit (at least for the getcwd()
179     and long path name test it goes down to under a second, and not 10+ seconds
180     like before). Also warn if we skip checking due to the canonicalized path
181     being too long.
182    
183     11 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
184 azarah 118 More comment/readability cleanups.
185    
186 azarah 117 10 June 2005; Martin Schlemmer <azarah@gentoo.org> canonicalize.c, getcwd.c,
187     sandbox_futils.c, libsandbox.c:
188     Some strncpy/strncat and other cleanups.
189    
190 azarah 115 * sandbox-1.2.9 (2005/06/09)
191    
192 azarah 114 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
193     Move symlink hack down a bit to try and minimize on the amount of lstat()
194     calls we do.
195    
196 azarah 113 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
197     Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
198    
199 azarah 112 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
200     Add wrapper for access() function, bug #85413.
201    
202 azarah 111 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
203     Use generic getcwd() implementation from uclibc - should be more portable
204     and looks a bit cleaner.
205    
206 azarah 110 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
207     Make sure our true_* pointers are initialized to NULL, and that we check for
208     all references that they are valid.
209    
210 azarah 109 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
211     Be default we will fail if the path name we try to canonicalize is too long.
212     This however could cause issues with some things (bug #94630 and #21766), so
213     if fail_nametoolong == 0, canonicalize() will return a null length string and
214     do not fail.
215    
216 azarah 108 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
217     Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
218     make sure we re-export the new TMPDIR environment variable.
219    
220 azarah 106 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
221     Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
222     by Marcus D. Hanwell <cryos@gentoo.org>.
223    
224 azarah 105 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
225     Add /dev/console to write list, bug #38588.
226    
227 azarah 102 * sandbox-1.2.8 (2005/05/13)
228    
229 azarah 99 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
230 azarah 101 sandbox.h, sandbox_futils.c:
231     General cleanups.
232    
233     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
234 azarah 100 sandbox.h:
235     Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
236    
237     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
238 azarah 99 sandbox.h, sandbox_futils.c:
239     Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
240     to use TMPDIR if present in environment.
241    
242 azarah 98 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
243     Remove sandbox_log_file from main() as its no longer used.
244    
245 azarah 97 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
246     sandbox_futils.c:
247     Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
248     if already exported when sandbox started). Fix get_sandbox_log() and new
249     get_sandbox_debug_log() to not use already exported environment variables if
250     they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
251     SB_PATH_MAX fixes.
252    
253 azarah 94 * sandbox-1.2.7 (2005/05/12)
254    
255 azarah 93 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
256     sandbox_futils.c:
257     More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
258    
259 azarah 92 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
260     Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
261     with '(null)' in it if we did not call sandbox with absolute path.
262    
263 azarah 89 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
264 azarah 91 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
265     for the child.
266    
267     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
268 azarah 90 Remove global preload_adaptable as it is no longer used.
269    
270     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
271 azarah 89 Rewrite environment stuff to only be set when execve'ing the child process
272     to try and avoid issues like bug #91541 that causes sandbox to crash if
273     we set LD_PRELOAD sandbox side already.
274    
275 azarah 87 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
276 azarah 88 Move print_sandbox_log() up to make things neater.
277    
278     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
279 azarah 87 Remove load_preload_libs(), as its not used anymore.
280    
281 azarah 83 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
282 azarah 86 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
283    
284     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
285 azarah 84 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
286    
287     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
288 azarah 83 Remove ld.so.preload crap - we are not going to use it again.
289    
290 azarah 82 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
291     Fix typo in code that checks if we got valid group information, causing a
292     segmentation fault, bug #91637.
293    
294 azarah 79 * sandbox-1.2.6 (2005/05/10)
295    
296 azarah 78 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
297     Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
298     for some odd reason, bug #91541.
299    
300 azarah 77 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
301     Fix typo (sizeof -> strlen).
302    
303 ferringb 76 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
304     rewrote the sbcontext caching code so it accounts for env changes since lib
305     initialization.
306    
307 azarah 75 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
308     We create libctest.c via configure, so no need to keep it around. Do some
309     cleanup related to libctest.c and libctest during configure.
310    
311 azarah 74 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
312     Add rename support of symlinks pointing to protected files/directories.
313    
314 azarah 72 * sandbox-1.2.5 (2005/05/04)
315    
316 azarah 71 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
317     sandbox.bashrc:
318     Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
319     already set, init of the env vars fails for some reason, so do this later on,
320     and do not warn (bug #91431).
321    
322 azarah 70 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
323     sandbox.bashrc:
324     Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
325    
326 azarah 68 * sandbox-1.2.4 (2005/05/03)
327    
328 azarah 66 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
329     Do not init the env entries with each call, as it creates too many calls to
330 azarah 67 lstat, etc. Should speedup things a bit, bug #91040.
331 azarah 66
332 azarah 65 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
333     Add /dev/pty to default write list. Noticed by Morfic.
334    
335 vapier 62 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
336     sandbox.h:
337     uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
338     exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
339    
340 azarah 59 * sandbox-1.2.3 (2005/04/29)
341    
342 azarah 56 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
343     Do not check for (*&#$(* CXX or F77.
344    
345 azarah 54 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
346     Do not append '/' to pathname in filter_path() if it already ends with it.
347    
348 vapier 53 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
349     With az's help, clean up autotools to work with cross-compiling.
350    
351 azarah 59 * sandbox-1.2.2 (2005/04/28)
352 azarah 48
353 azarah 47 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
354     Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
355     have issues; bug #90592.
356    
357 azarah 59 * sandbox-1.2.1 (2005/04/23)
358 azarah 44
359 azarah 43 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
360     getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
361     Make sure all functions used in libsandbox.c is declared static. Define
362     SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
363     linking with its object. Hopefully this will fix bug #90153.
364    
365 azarah 59 * sandbox-1.2 (2005/04/23)
366 azarah 46
367 azarah 40 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
368     Allow lchown a symlink in write-allowed path pointing to write-denied
369     target.
370    
371 genone 39 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
372     Also show resolved symlink names in the log.
373    
374 azarah 37 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
375     Seems -nostdlib was the problem with the constructor/destructor - remove it
376     from Makefile.am, and change the constructor/destructor names again.
377    
378 azarah 36 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
379     Also rename the _init() and _fini() declarations.
380    
381 azarah 35 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
382     Fixup the constructor/destructor function names again (they should be _init()
383     and _fini() it seems, and not being called caused sandbox_lib_path to be
384     unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
385     Add both the path in given SANDBOX_x variable, as well as its symlink
386     resolved path in init_env_entries(). Modify filter_path() to be able to
387     resolve paths without resolving symlinks, as well as to be able to resolve
388     symlinks. Fix a possible segfault in check_access(). Add symlink resolving
389     to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
390     for bug #31019 cause access violations if we try to remove a symlink that is
391     not in protected path, but points to a protected path. Fix a memory leak in
392     sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
393     (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
394     (pid_string was uninitialized). General syntax cleanups.
395    
396 ferringb 34 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
397     infamous "pids file is not a regular file" w/out newline bug.
398    
399 ferringb 33 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
400     Correct libc_version path detection, since it was screwing up if libdir !=
401     "/lib/".
402    
403     02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
404 azarah 32 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
405    
406 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
407 azarah 31 Fix symbols.in not added to dist.
408    
409 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
410 azarah 30 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
411     White space fixes.
412    
413 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
414 azarah 30 configure.in, getcwd.c, libsandbox.c, symbols.in:
415 azarah 29 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
416     getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
417     for glibc and other libc's that use this. Update libsandbox.c to use these
418     symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
419     process unset it.
420    
421 ferringb 33 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
422 ferringb 28 killed off _init and _fini in favor of
423     void __attribute__ ((constructor)) init_func and
424     void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
425    
426 ferringb 26 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
427     canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
428     having the hick-ups.
429    
430 ferringb 24 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
431     Makefile.am: Fixed compilation.
432    
433 ferringb 18 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
434     Gutted the bugger so it stops checking for a c++ and fortran compiler.
435     Do *not* regenerate aclocal.m4 for making a release until a better
436     solution is created.
437    
438 ferringb 16 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
439     Removal of more hardcoded paths.
440    
441 ferringb 13 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
442     sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
443    
444     19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
445 ferringb 6 Sandbox is now autotooled, create-localdecls needs to be killed and the code
446     shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
447     are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
448     To get to a point of testing, automake && autoconf; created requisite files w/
449     a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
450     /lib and /usr/lib/portage/bin.
451    
452 ferringb 2 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
453     closing out bug #70225, potential overflow of the sandbox_pids_file var.
454    
455     07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
456     (think it was at least) allows intermixing of code and data segments. bug #70351
457     should be fixed by this.
458    
459     03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
460     futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
461    
462     02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
463     Seth Robertson that tracked down all adjuct flags for read operations that
464     do not invoke a write operation.
465    
466     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
467     Another fix from jstubbs regarding a free() on a stack variable for the
468     environment -- tracking now prevents extraneous free()'s segfault.
469    
470     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
471     J. Stubbs tracked down a new bug where mkdir was failing to the patch on
472     the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
473     Also remove the errno = ESUCCESS settings as documentation points out that
474     a library isn't allowed to do that.
475    
476     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
477     file_security_check() function to check random potential exploits on files
478     that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
479     the 'system-crippling' exploits (bug 21923) and catches a few other
480     potential problems.
481    
482     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
483     32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
484    
485     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
486     bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
487     Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
488    
489     29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
490     Fix permissions and group of pids file and logs. Permissions should be 0664
491     and group should be 'portage'. Bug #34260.
492    
493     28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
494     Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
495     to the real execve (in our execve wrapper). Seems that on some arches (sparc
496     among others) do not allow us to tamper with the readonly copy passed to
497     execve, so pass our own copy of the environment. Bug #42290.
498    
499     11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
500     Changed tail to head and added a notice about duration of glibc check.
501    
502     21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
503     Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
504     as there isn't a guarentee that it is dynamic.
505    
506     02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
507     If 'file' passed to before_syscall(const char *func, const char *file) is
508     invalid, we should set errno to ENOENT, and not EINVAL. This should
509     close bug #32238.
510    
511     14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
512     Fix a bug that occurs mainly on 64bit arch, where the file passed to
513     the functions we wrap, is invalid, and then cause canonicalize to pass
514     garbage to before_syscall(), thanks to great detective work from
515     Andrea Luzzardi <al@sig11.org> (bug #29846).
516    
517     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
518     Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
519    
520     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
521     Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
522     only checked the destination patch, and not the source, so we could move
523     a protected file to a unprotected directory, and then delete/modify it.
524     Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
525    
526     12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
527     Added python2.3 to the predict section/variable.
528    
529     28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
530     sandbox.h, sandbox_futils.c :
531     Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
532     it is not set, it will revert to its old value.
533    
534     27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
535     Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
536     rather than failing with a violation, bug #29748.
537    
538     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
539     Fix canonicalize() to ignore calls with path = "".
540    
541     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
542     sandbox_futils.c, canonicalize.c :
543     Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
544     call handled strings larger than PATH_MAX (bug #21766). It however does not
545     work the same on 2.4 kernels.
546    
547     To fix, I added the posix implementation of getcwd() (from glibc cvs) that
548     do not need the system call. We use the default getcwd() function via a
549     wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
550     means the current directory was removed, OR that the the system call for
551     getcwd failed (curious is that it do not fail and return NULL or set
552     errno, but rather just truncate the retured directory - usually from the
553     start), and if so, we use the generic getcwd() function (__egetcwd). Note
554     that we do not use the generic version all the time, as it calls lstat()
555     a great number of times, and performance degrade much.
556    
557     29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
558     libsandbox.c :
559     Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
560    
561     22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
562     create-localdecls :
563     When checking path names of files accessed, we need to canonicalize it, else
564     it may be a symlink in a 'write allowed' directory pointing to a file in a
565     directory we should not have write access to.
566    
567     With something like coreutils-5.0, we have two problems:
568     1) One of the tests checks if getcwd() can return a path longer than
569     PATH_MAX. This test then tries to create a dir which even while
570     created local (mkdir("conftest2")), it ends up being resolved with
571     a name that is much larger than PATH_MAX. The problem now is that
572     canonicalize() have undefined behaviour when the path was too long
573     (returned wrongly truncated paths, etc), and pass the wrong path to
574     before_syscall() (causing the bogus sandbox violations).
575     2) The ecanonicalize() function we used, along with the canonicalize()
576     function did not support longer than PATH_MAX. This is partly a
577     cause for 1), but the error checking (rather lack of it) of calls
578     to erealpath() in canonicalize() was the prime reason for 1).
579    
580     As we do not use this canonicalized name to call the function, we resolve this
581     by fixing canonicalize() to do better error checking, and ecanonicalize() as
582     well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
583     While they will resolve paths properly now, and can check if a write/read is
584     allowed, the functions called from the sandboxed environment will still work
585     as expected.
586    
587     This should resolve bug #21766.
588    
589     06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
590     For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
591     it (bug #16298).
592    
593     Problem is that for some reason locale fopen's locale.alias with mode "rm".
594    
595     -------------------------------------------------------
596     nosferatu root # grep fopen locale.log
597     fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
598     nosferatu root #
599     --------------------------------------------------------
600    
601     I checked the source of locale, but it have fopen with mode 'r', so
602     not sure where the "rm" mode comes from. Anyhow, changed the check in
603     before_syscall_open_char() to also see mode "rm" as readonly.
604    
605     23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
606    
607     Add glibc-2.3 support.
608    
609     22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
610    
611     Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
612     operations releated to preload, as well as only try to modify ld.so.preload
613     if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
614     not using ld.so.preload. Fix to not write this instance of sandbox's pid
615     to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
616    
617     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
618    
619     Changed the LD to CC for hppa.
620    
621     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
622    
623     Killed the previous changes I made.
624    
625     17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
626    
627     Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
628    
629     09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
630    
631     Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
632    
633     16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
634    
635     Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
636     for this fix.
637    
638     4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
639    
640     sandbox_futils defined a dirname() function that was masking the same
641     function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
642     '/usr/lib/portage/bi/'). Fixed function to return expected results and
643     renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
644     11231.
645    
646     4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
647    
648     Fix a segfault in libsandbox.c if canonicalize() was called with
649     first parameter = NULL.
650    
651     1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
652    
653     Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
654     cleanup() for this.
655    
656     Change cleanup() in sandbox.c not to exit with fail status if
657     the pidsfile is missing. We really should still display sandbox
658     violations if they occured.
659    
660     31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
661    
662     Update cleanup() in sandbox.c to remove the PIDSFILE if this is
663     the last sandbox running.
664    
665     25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
666    
667     Major cleanups to mainly libsandbox.c again.
668    
669     22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
670    
671     Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
672     parties involved should please contact me so that we can fix it.
673    
674     Add opendir wrapper to libsandbox.c.
675    
676     21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
677    
678     Do some more cleanups to ecanonicalize(), as it dropped filenames in
679     rare cases (after my symlink cleanups), and caused glibc to bork.
680     These fixes went into canonicalize.c.
681    
682     20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
683    
684     Fix spawn_shell() and main() in sandbox.c to properly return fail
685     status.
686    
687     19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
688    
689     The new canonicalize() function in libsandbox.c also resolved symlinks,
690     which caused on cleaning sandbox errors if the symlink pointed to a
691     file in the live root. Ripped out canonicalize() and realpath() from
692     glibc; removed the symlink stuff, and changed them to ecanonicalize()
693     and erealpath().
694    
695     18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
696    
697     Ripped out all the wrappers, and implemented those of InstallWatch.
698     Losts of cleanups and bugfixes. Implement a execve that forces
699     $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
700     /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
701     sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
702     parts; it now have an install target.
703    
704     Reformat the whole thing to look somewhat like the reworked sandbox.c
705     and new sandbox.h and sandbox_futils.c from:
706    
707     Brad House <brad@mainstreetsoftworks.com>.
