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