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