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