Title:
Incorrect handling of icebp
Status in QEMU:
New
Bug description:
Wine conformance suite tests the behavior of various low-level Windows
API functions. One of the tests involves checking the interaction of
breakpoints and exceptions, and in particular the 'icebp' breakpoint.
This test works on a Windows XP machine running either on the metal or
in VMware ESX but fails when run in QEmu.
To reproduce the issue grab the attached 'exception.exe' file and run
it. If you get 'Test failed' lines like below then it means the
problem is still present:
exception.c:202: exception 0: 80000004 flags:0 addr:003F0000
exception.c:208: Test failed: 0: Wrong exception address 003F0000/003F0001
exception.c:214: this is the last test seen before the exception
exception: unhandled exception 80000004 at 003F0000
exception.c:202: exception 0: c0000027 flags:2 addr:7C80E0B9
exception.c:205: Test failed: 0: Wrong exception code c0000027/80000004
exception.c:208: Test failed: 0: Wrong exception address 7C80E0B9/003F0001
Note that this bug was not present in QEmu 1.1.2+dfsg-5 (Debian
Testing) but is now present in 1.4.0~rc0+dfsg-1exp (Debian
Experimental).

Actually this got fixed by the following Linux kernel commit:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=fd2a445a94d2ab6b39fb623dc02fee48d01a565a
commit fd2a445a94d2ab6b39fb623dc02fee48d01a565a (patch)
KVM: VMX: Advance rip to after an ICEBP instruction
When entering an exception after an ICEBP, the saved instruction
pointer should point to after the instruction.
