[uml-devel] SKAS-v8: RC2 released against 2.6.7 - 2.6.11-rc3-bk6 kernels

[Blaisorblade <blaisorblade@yahoo.it>]

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 <mcr@sandelman.ottawa.on.ca>. 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).
