Guest OS : Linux 2.6.15-1.2054_FC5 i686 (Fedora Core 5 i386)
Host OS: Linux 2.6.12-10-amd64-k8 #1 x86_64 (Ubuntu 5.10 amd64)
QEMU Version : today CVS compiled with kqemu support
KQEMU : 1.3.0pre6
Binary used : qemu-system-x86-64 (so kqemu user-mode is used)
I'm running the simple C code attached. With kqemu user-mode, this fails
(sigsegv) with the following warning in dmesg :
audit(1146505373.813:12): avc: denied { execheap } for pid=1860
comm="selfmodifying scontext=user_u:system_r:unconfined_t:s0
tcontext=user_u:system_r:unconfined_t:s0 tclass=process
Erreur de segmentation
Without kqemu enabled, it runs fine.
