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