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