It however does not + work the same on 2.4 kernels. + + To fix, I added the posix implementation of getcwd() (from glibc cvs) that + do not need the system call. We use the default getcwd() function via a + wrapper (egetcwd), and then lstat the returned path. If lstat fails, it + means the current directory was removed, OR that the the system call for + getcwd failed (curious is that it do not fail and return NULL or set + errno, but rather just truncate the retured directory - usually from the + start), and if so, we use the generic getcwd() function (__egetcwd). Note + that we do not use the generic version all the time, as it calls lstat() + a great number of times, and performance degrade much. + + 29 Jun 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls, + libsandbox.c : + Make sure SB_PATH_MAX will not wrap. Fix two possible memory leaks. + + 22 Jun 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, canonicalize.c + create-localdecls : + When checking path names of files accessed, we need to canonicalize it, else + it may be a symlink in a 'write allowed' directory pointing to a file in a + directory we should not have write access to. + + With something like coreutils-5.0, we have two problems: + 1) One of the tests checks if getcwd() can return a path longer than + PATH_MAX. This test then tries to create a dir which even while + created local (mkdir("conftest2")), it ends up being resolved with + a name that is much larger than PATH_MAX. The problem now is that + canonicalize() have undefined behaviour when the path was too long + (returned wrongly truncated paths, etc), and pass the wrong path to + before_syscall() (causing the bogus sandbox violations). + 2) The ecanonicalize() function we used, along with the canonicalize() + function did not support longer than PATH_MAX. This is partly a + cause for 1), but the error checking (rather lack of it) of calls + to erealpath() in canonicalize() was the prime reason for 1). + + As we do not use this canonicalized name to call the function, we resolve this + by fixing canonicalize() to do better error checking, and ecanonicalize() as + well as all functions in libsandbox.c to use a PATH_MAX of 'PATH_MAX * 2'. + While they will resolve paths properly now, and can check if a write/read is + allowed, the functions called from the sandboxed environment will still work + as expected. + + This should resolve bug #21766. + + 06 Apr 2003; Martin Schlemmer <azarah@gentoo.org> libsandbox.c : + For some reason sandbox fails with a 'open_wr' if you run 'locale -a' under + it (bug #16298). + + Problem is that for some reason locale fopen's locale.alias with mode "rm". + + ------------------------------------------------------- + nosferatu root # grep fopen locale.log + fopen("/usr/share/locale/locale.alias", "rm"ACCESS DENIED open_wr: /usr/share/locale/locale.alias + nosferatu root # + -------------------------------------------------------- + + I checked the source of locale, but it have fopen with mode 'r', so + not sure where the "rm" mode comes from. Anyhow, changed the check in + before_syscall_open_char() to also see mode "rm" as readonly. + + 23 Feb 2003; Martin Schlemmer <azarah@gentoo.org> create-localdecls : + + Add glibc-2.3 support. + + 22 Feb 2003; Martin Schlemmer <azarah@gentoo.org> sandbox.c : + + Some /etc/ld.so.preload fixes. Just changed the #if defines to cover all + operations releated to preload, as well as only try to modify ld.so.preload + if we can. Also modify to write the pid to /tmp/sandboxpids.tmp even when + not using ld.so.preload. Fix to not write this instance of sandbox's pid + to /tmp/sandboxpids.tmp on exit if this is not the last sandbox running. + + 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> Makefile : + + Changed the LD to CC for hppa. + + 22 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls : + + Killed the previous changes I made. + + 17 Feb 2003; Nicholas Jones <carpaski@gentoo.org> create-localdecls : + + Added parisc to BROKEN_RTLD_ARCHLIST to see if it we can fix the relocation probs. + + 09 Jan 2003; J Robert Ray <jrray@gentoo.org> sandbox.c : + + Don't segfault if $HOME isn't set, set $HOME to "/" instead. Fixes bug 10868. + + 16 Dec 2002; Martin Schlemmer <azarah@gentoo.org> create-localdecls : + + Fix memory leak for mips, bug #12236. Thanks to Torgeir Hansen <torgeir@trenger.ro> + for this fix. + + 4 Dec 2002; J Robert Ray <jrray@gentoo.org> sandbox.h sandbox_futils.c : + + sandbox_futils defined a dirname() function that was masking the same + function in glibc and was broken (e.g.: SANDBOX_DIR was being set to + '/usr/lib/portage/bi/'). Fixed function to return expected results and + renamed it to sb_dirname() to no longer mask the glibc function. Closes bug + 11231. + + 4 Dec 2002; Martin Schlemmer <azarah@gentoo.org> : + + Fix a segfault in libsandbox.c if canonicalize() was called with + first parameter = NULL. + + 1 Sep 2002; Martin Schlemmer <azarah@gentoo.org> : + + Fix my braindead 'return 1;' in a void function. Updated sandbox.c, + cleanup() for this. + + Change cleanup() in sandbox.c not to exit with fail status if + the pidsfile is missing. We really should still display sandbox + violations if they occured. + + 31 Aug 2002; Martin Schlemmer <azarah@gentoo.org> : + + Update cleanup() in sandbox.c to remove the PIDSFILE if this is + the last sandbox running. + + 25 Aug 2002; Martin Schlemmer <azarah@gentoo.org> : + + Major cleanups to mainly libsandbox.c again. + + 22 Aug 2002; Martin Schlemmer <azarah@gentoo.org> : + + Add copyrights to sandbox.h and sandbox_futils.h. If wrong, the + parties involved should please contact me so that we can fix it. + + Add opendir wrapper to libsandbox.c. + + 21 Aug 2002; Martin Schlemmer <azarah@gentoo.org> : + + Do some more cleanups to ecanonicalize(), as it dropped filenames in + rare cases (after my symlink cleanups), and caused glibc to bork. + These fixes went into canonicalize.c. + + 20 Aug 2002; Martin Schlemmer <azarah@gentoo.org> : + + Fix spawn_shell() and main() in sandbox.c to properly return fail + status. + + 19 Aug 2002; Martin Schlemmer <azarah@gentoo.org> : + + The new canonicalize() function in libsandbox.c also resolved symlinks, + which caused on cleaning sandbox errors if the symlink pointed to a + file in the live root. Ripped out canonicalize() and realpath() from + glibc; removed the symlink stuff, and changed them to ecanonicalize() + and erealpath(). + + 18 Aug 2002; Martin Schlemmer <azarah@gentoo.org> : + + Ripped out all the wrappers, and implemented those of InstallWatch. + Losts of cleanups and bugfixes. Implement a execve that forces + $LIBSANDBOX in $LD_PRELOAD. We can now thus do away with the feared + /etc/ld.so.preload (*g*) ... Made the needed changes to sandbox.c, + sandbox.h and sandbox_futils.c. Rewrote the Makefile for most + parts; it now have an install target. + + Reformat the whole thing to look somewhat like the reworked sandbox.c + and new sandbox.h and sandbox_futils.c from: + + Brad House <brad@mainstreetsoftworks.com>. + + Additional Copyrights now due to the InstallWatch code: + + Copyright (C) 1998-9 Pancrazio `Ezio' de Mauro <p@demauro.net> + |
