This time, I've announced this on my homepage, since I'd like to get some more testing.
Things I've forgot: * make it apply easily on Fedora kernels. This should simply mean moving the TIF_SYSCALL_EMU to place no.8, to leave a slot free for _DB7, needed for 4g4g or something like that and using testw instead of testb for testing against it. Summary of changes against -V7 (also put in the "ChangeLog" page): * for kernels >=2.6.10, in the splitout, various patches were folded together. * rename-modify-ldt-to-avoid-conflicts.patch: fix the reported ATI module compile problem by renaming modify_ldt to __modify_ldt. * ptrace_ldt-reload-smp-fix.patch: fix a SMP-host bug noticed by Bodo Stroesser. * skas-add-locking-for-mm-switch.patch: from me, add correct locking to PTRACE_SWITCH_MM to avoid races. Someone please test with SMP hosts / with spinlock debugging enabled, to check for any possible deadlock. I'll do this in next days, too. * skas-reorganize and skas-add-SYSEMU_SINGLESTEP: from Bodo Stroesser, they add the SYSEMU_SINGLESTEP mode. For 2.6.9 and beyond, I've cleaned up a lot the second one to ease porting to 2.6.10. * sysaudit-singlestep-umlhost.patch: for host >= 2.6.9, it fixes a bad interaction between syscall auditing and ptracing. A version of this must also go in 2.6.11. * fix-dumpable-handling.patch: this implemented a feature / bug fix requested by Michael Richardson <[EMAIL PROTECTED]>. I.e., with this, in normal cases, UML *is* allowed to dump core and be seen inside /proc - (until now it was treated as if it was a setuid process or one which changed UID / GID). If I did any error, however, it could allow privilege escalation. Well, I've thought a bit about this, however I'll think even more before putting it into a release (I wrote this more than one month ago). -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
