5 azarah 113 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
6     Add hack to allow writing to /proc/self/fd (or /dev/fd), bug #91516.
7    
8 azarah 112 09 June 2005; Martin Schlemmer <azarah@gentoo.org> symbols.in, libsandbox.c:
9     Add wrapper for access() function, bug #85413.
10    
11 azarah 111 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c:
12     Use generic getcwd() implementation from uclibc - should be more portable
13     and looks a bit cleaner.
14    
15 azarah 110 09 June 2005; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c:
16     Make sure our true_* pointers are initialized to NULL, and that we check for
17     all references that they are valid.
18    
19 azarah 109 09 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
20     Be default we will fail if the path name we try to canonicalize is too long.
21     This however could cause issues with some things (bug #94630 and #21766), so
22     if fail_nametoolong == 0, canonicalize() will return a null length string and
23     do not fail.
24    
25 azarah 108 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c:
26     Do not abort if TMPDIR is not valid, but rather use '/tmp', bug #94360. Also
27     make sure we re-export the new TMPDIR environment variable.
28    
29 azarah 106 08 June 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
30     Fix incorrect free of non-malloc'd array, bug #92313 and #94020. Fix noted
31     by Marcus D. Hanwell <cryos@gentoo.org>.
32    
33 azarah 105 08 June 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
34     Add /dev/console to write list, bug #38588.
35    
36 azarah 102 * sandbox-1.2.8 (2005/05/13)
37    
38 azarah 99 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
39 azarah 101 sandbox.h, sandbox_futils.c:
40     General cleanups.
41    
42     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
43 azarah 100 sandbox.h:
44     Various LD_PRELOAD cleanups. Do not unset LD_PRELOAD for parent.
45    
46     13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
47 azarah 99 sandbox.h, sandbox_futils.c:
48     Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
49     to use TMPDIR if present in environment.
50    
51 azarah 98 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
52     Remove sandbox_log_file from main() as its no longer used.
53    
54 azarah 97 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
55     sandbox_futils.c:
56     Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
57     if already exported when sandbox started). Fix get_sandbox_log() and new
58     get_sandbox_debug_log() to not use already exported environment variables if
59     they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
60     SB_PATH_MAX fixes.
61    
62 azarah 94 * sandbox-1.2.7 (2005/05/12)
63    
64 azarah 93 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
65     sandbox_futils.c:
66     More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
67    
68 azarah 92 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
69     Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
70     with '(null)' in it if we did not call sandbox with absolute path.
71    
72 azarah 89 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
73 azarah 91 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
74     for the child.
75    
76     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
77 azarah 90 Remove global preload_adaptable as it is no longer used.
78    
79     12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
80 azarah 89 Rewrite environment stuff to only be set when execve'ing the child process
81     to try and avoid issues like bug #91541 that causes sandbox to crash if
82     we set LD_PRELOAD sandbox side already.
83    
84 azarah 87 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
85 azarah 88 Move print_sandbox_log() up to make things neater.
86    
87     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
88 azarah 87 Remove load_preload_libs(), as its not used anymore.
89    
90 azarah 83 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
91 azarah 86 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
92    
93     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
94 azarah 84 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
95    
96     11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
97 azarah 83 Remove ld.so.preload crap - we are not going to use it again.
98    
99 azarah 82 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
100     Fix typo in code that checks if we got valid group information, causing a
101     segmentation fault, bug #91637.
102    
103 azarah 79 * sandbox-1.2.6 (2005/05/10)
104    
105 azarah 78 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
106     Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
107     for some odd reason, bug #91541.
108    
109 azarah 77 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
110     Fix typo (sizeof -> strlen).
111    
112 ferringb 76 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
113     rewrote the sbcontext caching code so it accounts for env changes since lib
114     initialization.
115    
116 azarah 75 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
117     We create libctest.c via configure, so no need to keep it around. Do some
118     cleanup related to libctest.c and libctest during configure.
119    
120 azarah 74 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
121     Add rename support of symlinks pointing to protected files/directories.
122    
123 azarah 72 * sandbox-1.2.5 (2005/05/04)
124    
125 azarah 71 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
126     sandbox.bashrc:
127     Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
128     already set, init of the env vars fails for some reason, so do this later on,
129     and do not warn (bug #91431).
130    
131 azarah 70 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
132     sandbox.bashrc:
133     Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
134    
135 azarah 68 * sandbox-1.2.4 (2005/05/03)
136    
137 azarah 66 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
138     Do not init the env entries with each call, as it creates too many calls to
139 azarah 67 lstat, etc. Should speedup things a bit, bug #91040.
140 azarah 66
141 azarah 65 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
142     Add /dev/pty to default write list. Noticed by Morfic.
143    
144 vapier 62 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
145     sandbox.h:
146     uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
147     exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
148    
149 azarah 59 * sandbox-1.2.3 (2005/04/29)
150    
151 azarah 56 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
152     Do not check for (*&#$(* CXX or F77.
153    
154 azarah 54 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
155     Do not append '/' to pathname in filter_path() if it already ends with it.
156    
157 vapier 53 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
158     With az's help, clean up autotools to work with cross-compiling.
159    
160 azarah 59 * sandbox-1.2.2 (2005/04/28)
161 azarah 48
162 azarah 47 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
163     Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
164     have issues; bug #90592.
165    
166 azarah 59 * sandbox-1.2.1 (2005/04/23)
167 azarah 44
168 azarah 43 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
169     getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
170     Make sure all functions used in libsandbox.c is declared static. Define
171     SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
172     linking with its object. Hopefully this will fix bug #90153.
173    
174 azarah 59 * sandbox-1.2 (2005/04/23)
175 azarah 46
176 azarah 40 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
177     Allow lchown a symlink in write-allowed path pointing to write-denied
178     target.
179    
180 genone 39 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
181     Also show resolved symlink names in the log.
182    
183 azarah 37 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
184     Seems -nostdlib was the problem with the constructor/destructor - remove it
185     from Makefile.am, and change the constructor/destructor names again.
186    
187 azarah 36 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
188     Also rename the _init() and _fini() declarations.
189    
190 azarah 35 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
191     Fixup the constructor/destructor function names again (they should be _init()
192     and _fini() it seems, and not being called caused sandbox_lib_path to be
193     unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
194     Add both the path in given SANDBOX_x variable, as well as its symlink
195     resolved path in init_env_entries(). Modify filter_path() to be able to
196     resolve paths without resolving symlinks, as well as to be able to resolve
197     symlinks. Fix a possible segfault in check_access(). Add symlink resolving
198     to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
199     for bug #31019 cause access violations if we try to remove a symlink that is
200     not in protected path, but points to a protected path. Fix a memory leak in
201     sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
202     (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
203     (pid_string was uninitialized). General syntax cleanups.
204    
205 ferringb 34 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
206     infamous "pids file is not a regular file" w/out newline bug.
207    
208 ferringb 33 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
209     Correct libc_version path detection, since it was screwing up if libdir !=
210     "/lib/".
211    
212     02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
213 azarah 32 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
214    
215 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
216 azarah 31 Fix symbols.in not added to dist.
217    
218 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
219 azarah 30 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
220     White space fixes.
221    
222 ferringb 33 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
223 azarah 30 configure.in, getcwd.c, libsandbox.c, symbols.in:
224 azarah 29 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
225     getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
226     for glibc and other libc's that use this. Update libsandbox.c to use these
227     symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
228     process unset it.
229    
230 ferringb 33 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
231 ferringb 28 killed off _init and _fini in favor of
232     void __attribute__ ((constructor)) init_func and
233     void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
234    
235 ferringb 26 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
236     canonicalize.c, getcwd.c: Fixed compilation *again*. Hopefully cvs is done
237     having the hick-ups.
238    
239 ferringb 24 04 Dec 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, getcwd.c,
240     Makefile.am: Fixed compilation.
241    
242 ferringb 18 01 Dec 2004; Brian Harring <ferringb@gentoo.org> aclocal.m4:
243     Gutted the bugger so it stops checking for a c++ and fortran compiler.
244     Do *not* regenerate aclocal.m4 for making a release until a better
245     solution is created.
246    
247 ferringb 16 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, sandbox_futils.c:
248     Removal of more hardcoded paths.
249    
250 ferringb 13 20 Nov 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in,
251     sandbox_futils.c: tweaks to install sandbox.bashrc, and use it.
252    
253     19 Nov 2004; Brian Harring <ferringb@gentoo.org>:
254 ferringb 6 Sandbox is now autotooled, create-localdecls needs to be killed and the code
255     shifted into configure.in. Currently builds *one* libsandbox.so- if multiple
256     are desired (-m64 and -m32 for amd64), the ebuild should do it (imo).
257     To get to a point of testing, automake && autoconf; created requisite files w/
258     a(utomake|clocal)-1.8, and autoconf 2.59. Installs to /usr/, instead of
259     /lib and /usr/lib/portage/bin.
260    
261 ferringb 2 14 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox.c:
262     closing out bug #70225, potential overflow of the sandbox_pids_file var.
263    
264     07 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c: c99 standard,
265     (think it was at least) allows intermixing of code and data segments. bug #70351
266     should be fixed by this.
267    
268     03 Nov 2004; Brian Harring <ferringb@gentoo.org> libsandbox.c, sandbox_futils.c:
269     futils fix from bug #65201 via solar, and libsandbox log path checks via #69137
270    
271     02 Aug 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Code from
272     Seth Robertson that tracked down all adjuct flags for read operations that
273     do not invoke a write operation.
274    
275     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
276     Another fix from jstubbs regarding a free() on a stack variable for the
277     environment -- tracking now prevents extraneous free()'s segfault.
278    
279     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c, sandbox.c:
280     J. Stubbs tracked down a new bug where mkdir was failing to the patch on
281     the lstat in mkdir... it now only returns 0 or -1 as documented for mkdir.
282     Also remove the errno = ESUCCESS settings as documentation points out that
283     a library isn't allowed to do that.
284    
285     04 Apr 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c: Added a
286     file_security_check() function to check random potential exploits on files
287     that sandbox is to load and read -- Normally sandboxpids.tmp. This fixes
288     the 'system-crippling' exploits (bug 21923) and catches a few other
289     potential problems.
290    
291     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> Makefile: Updates for
292     32/64 bit sandbox. Made CC and LD '?=' values to allow passed in CC to work.
293    
294     20 Mar 2004; Nicholas Jones <carpaski@gentoo.org> libsandbox.c:
295     bug 42048 -- Fixed the lstat/errno conditions for mkdir <caleb@g.o>.
296     Added the 64/32 bit sandbox patch for AMD64 bug 32963 <brad/azarah>.
297    
298     29 Feb 2004; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox_futils.c :
299     Fix permissions and group of pids file and logs. Permissions should be 0664
300     and group should be 'portage'. Bug #34260.
301    
302     28 Feb 2004; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
303     Besides a small cleanup, redo how we replace LD_PRELOAD in the environ passed
304     to the real execve (in our execve wrapper). Seems that on some arches (sparc
305     among others) do not allow us to tamper with the readonly copy passed to
306     execve, so pass our own copy of the environment. Bug #42290.
307    
308     11 Jan 2004; Nicholas Jones <carpaski@gentoo.org> create-decls:
309     Changed tail to head and added a notice about duration of glibc check.
310    
311     21 Dec 2003; Nicholas Jones <carpaski@gentoo.org> create-decls:
312     Changed the glibc subversion check to use /usr/bin/* instead of /bin/sh
313     as there isn't a guarentee that it is dynamic.
314    
315     02 Nov 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
316     If 'file' passed to before_syscall(const char *func, const char *file) is
317     invalid, we should set errno to ENOENT, and not EINVAL. This should
318     close bug #32238.
319    
320     14 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
321     Fix a bug that occurs mainly on 64bit arch, where the file passed to
322     the functions we wrap, is invalid, and then cause canonicalize to pass
323     garbage to before_syscall(), thanks to great detective work from
324     Andrea Luzzardi <al@sig11.org> (bug #29846).
325    
326     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
327     Add a uClibc detection patch from Peter S. Mazinger <ps.m@gmx.net>.
328    
329     13 Oct 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
330     Fix a bug in libsandbox.c 's checking in the rename wrapper - it basically
331     only checked the destination patch, and not the source, so we could move
332     a protected file to a unprotected directory, and then delete/modify it.
333     Thanks to Andrea Luzzardi (scox) <al@sig11.org>, bug #30992, for this fix.
334    
335     12 Oct 2003; Nicholas Jones <carpaski@gentoo.org> sandbox.c :
336     Added python2.3 to the predict section/variable.
337    
338     28 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
339     sandbox.h, sandbox_futils.c :
340     Add support to set the pids file via SANDBOX_PIDS_FILE at startup. If
341     it is not set, it will revert to its old value.

343     27 Sep 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
344     Fix our mkdir wrapper to check if the dir exist, and return EEXIST if so,
345     rather than failing with a violation, bug #29748.
346    
347     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
348     Fix canonicalize() to ignore calls with path = "".
349    
350     27 Jul 2003; Martin Schlemmer <azarah@gentoo.org> getcwd.c, libsandbox.c,
351     sandbox_futils.c, canonicalize.c :
352     Once again coreutils fails, as my systems had 2.5 kernel, the getcwd system
353     call handled strings larger than PATH_MAX (bug #21766). It however does not
354     work the same on 2.4 kernels.
355    
356     To fix, I added the posix implementation of getcwd() (from glibc cvs) that
357     do not need the system call. We use the default getcwd() function via a
358     wrapper (egetcwd), and then lstat the returned path. If lstat fails, it
359     means the current directory was removed, OR that the the system call for
360     getcwd failed (curious is that it do not fail and return NULL or set
361     errno, but rather just truncate the retured directory - usually from the
362     start), and if so, we use the generic getcwd() function (__egetcwd). Note
363     that we do not use the generic version all the time, as it calls lstat()
364     a great number of times, and performance degrade much.
365    
366     29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls,
367     libsandbox.c :
368     Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks.
369    
370     22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c
371     create-localdecls :
372     When checking path names of files accessed, we need to canonicalize it, else
373     it may be a symlink in a 'write allowed' directory pointing to a file in a
374     directory we should not have write access to.
375    
376     With something like coreutils-5.0, we have two problems:
377     1) One of the tests checks if getcwd() can return a path longer than
378     PATH_MAX. This test then tries to create a dir which even while
379     created local (mkdir("conftest2")), it ends up being resolved with
380     a name that is much larger than PATH_MAX. The problem now is that
381     canonicalize() have undefined behaviour when the path was too long
382     (returned wrongly truncated paths, etc), and pass the wrong path to
383     before_syscall() (causing the bogus sandbox violations).
384     2) The ecanonicalize() function we used, along with the canonicalize()
385     function did not support longer than PATH_MAX. This is partly a
386     cause for 1), but the error checking (rather lack of it) of calls
387     to erealpath() in canonicalize() was the prime reason for 1).
388    
389     As we do not use this canonicalized name to call the function, we resolve this
390     by fixing canonicalize() to do better error checking, and ecanonicalize() as
391     well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'.
392     While they will resolve paths properly now, and can check if a write/read is
393     allowed, the functions called from the sandboxed environment will still work
394     as expected.
395    
396     This should resolve bug #21766.
397    
398     06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c :
399     For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under
400     it (bug #16298).
401    
402     Problem is that for some reason locale fopen's locale.alias with mode "rm".
403    
404     -------------------------------------------------------
405     nosferatu root # grep fopen locale.log
406     fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias
407     nosferatu root #
408     --------------------------------------------------------
409    
410     I checked the source of locale, but it have fopen with mode 'r', so
411     not sure where the "rm" mode comes from. Anyhow, changed the check in
412     before_syscall_open_char() to also see mode "rm" as readonly.
413    
414     23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
415    
416     Add glibc-2.3 support.
417    
418     22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c :
419    
420     Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all
421     operations releated to preload, as well as only try to modify ld.so.preload
422     if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when
423     not using ld.so.preload. Fix to not write this instance of sandbox's pid
424     to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running.
425    
426     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile :
427    
428     Changed the LD to CC for hppa.
429    
430     22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
431    
432     Killed the previous changes I made.
433    
434     17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls :
435    
436     Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs.
437    
438     09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c :
439    
440     Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868.
441    
442     16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls :
443    
444     Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro>
445     for this fix.
446    
447     4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c :
448    
449     sandbox_futils defined a dirname() function that was masking the same
450     function in glibc and was broken (e.g.: SANDBOX_DIR was being set to
451     '/usr/lib/portage/bi/'). Fixed function to return expected results and
452     renamed it to sb_dirname() to no longer mask the glibc function. Closes bug
453     11231.
454    
455     4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> :
456    
457     Fix a segfault in libsandbox.c if canonicalize() was called with
458     first parameter = NULL.
459    
460     1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> :
461    
462     Fix my braindead 'return 1;' in a void function. Updated sandbox.c,
463     cleanup() for this.
464    
465     Change cleanup() in sandbox.c not to exit with fail status if
466     the pidsfile is missing. We really should still display sandbox
467     violations if they occured.
468    
469     31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
470    
471     Update cleanup() in sandbox.c to remove the PIDSFILE if this is
472     the last sandbox running.
473    
474     25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
475    
476     Major cleanups to mainly libsandbox.c again.
477    
478     22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
479    
480     Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the
481     parties involved should please contact me so that we can fix it.
482    
483     Add opendir wrapper to libsandbox.c.
484    
485     21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
486    
487     Do some more cleanups to ecanonicalize(), as it dropped filenames in
488     rare cases (after my symlink cleanups), and caused glibc to bork.
489     These fixes went into canonicalize.c.
490    
491     20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
492    
493     Fix spawn_shell() and main() in sandbox.c to properly return fail
494     status.
495    
496     19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
497    
498     The new canonicalize() function in libsandbox.c also resolved symlinks,
499     which caused on cleaning sandbox errors if the symlink pointed to a
500     file in the live root. Ripped out canonicalize() and realpath() from
501     glibc; removed the symlink stuff, and changed them to ecanonicalize()
502     and erealpath().
503    
504     18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> :
505    
506     Ripped out all the wrappers, and implemented those of InstallWatch.
507     Losts of cleanups and bugfixes. Implement a execve that forces
508     $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared
509     /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c,
510     sandbox.h and sandbox_futils.c. Rewrote the Makefile for most
511     parts; it now have an install target.
512    
513     Reformat the whole thing to look somewhat like the reworked sandbox.c
514     and new sandbox.h and sandbox_futils.c from:
515    
516     Brad House <brad@mainstreetsoftworks.com>.
