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