2014-09-08linux-user: Handle PPC64 ELFv2 Function PointersTom Musta1-10/+30
Function pointers in the 64-bit ELFv2 PowerPC ABI are actual (internal) entry point addresses. However, when invoking a function via a function pointer, GPR 12 must also be set to this address so that the TOC may be handled properly. Add this support to the invocation of a signal handler.

2014-09-08linux-user: Implement do_setcontext for PPC64Tom Musta1-5/+5
Eliminate the stub for the do_setcontext() function for TARGET_PPC64. The implementation re-uses the existing TARGET_PPC32 code with the only change being the computation of the address of the register save area.

2014-09-08linux-user: Properly Dereference PPC64 ELFv1 Signal Handler PointerTom Musta1-0/+29
Properly dereference 64-bit PPC ELF V1 ABIT function pointers to signal handlers. On this platform, function pointers are pointers to structures and the first 64 bits of such a structure contains the function's entry point. The second 64 bits contains the TOC pointer, which must be placed into GPR 2. Signed-off-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2014-09-08linux-user: Enable Signal Handlers on PPC64Tom Musta1-48/+73
Enable the 64-bit PowerPC signal handling code that was previously disabled via #ifdefs. Specifically: - Move the target_mcontext (register save area) structure and append it to the 64-bit target_sigcontext structure. This provides the space on the stack for saving and restoring context. - Define the target_rt_sigframe for 64-bit. - Adjust the setup_frame and setup_rt_frame routines to properly select the target_mcontext area and trampoline within the stack frame; tthis is different for 32-bit and 64-bit implementations. - Adjust the do_setcontext stub for 64-bit so that it compiles without warnings. The 64-bit signal handling code is still not functional after this change; but the 32-bit code is. Subsequent changes will address specific issues with the 64-bit code.

2014-09-08linux-user: Split PPC Trampoline Encoding from Register SaveTom Musta1-6/+12
Split the encoding of the PowerPC sigreturn trampoline from the saving of register state onto the signal handler stack.

2014-09-08linux-user: Fix Stack Pointer Bug in PPC setup_rt_frameTom Musta1-1/+1
The code that sets the stack frame back pointer is incorrect for the setup_rt_frame() code; qemu will abort (SIGSEGV) in some environments. The setup_frame code was fixed in commit beb526b12134a6b6744125deec5a7fe24a8f92e3 but the setup_rt_frame code was not. Make the setup_rt_frame code consistent with the setup_frame code.

2014-03-17linux-user: Don't allow guest to block SIGSEGVPeter Maydell1-1/+61
Don't allow the linux-user guest to block SIGSEGV -- QEMU needs this signal to detect accesses to pages which it has marked read-only because it has cached translated code from them. We implement this by making the do_sigprocmask() wrapper suppress SIGSEGV when doing the host process signal mask manipulation; instead we store the current state of SIGSEGV in the TaskState struct. If we get a SIGSEGV for the guest when the guest has blocked the signal, we treat it as if the default SEGV handler was in place, as the kernel does for forced SIGSEGV delivery. This patch is based on an idea by Alex Barcelo, but rather than simply lying to the guest about the SIGSEGV state we track it.

Create a wrapper for signal mask changes initiated by the guest; (this includes syscalls and also the sigreturns from signal.c) this will give us a place to put code which prevents the guest from changing the handling of signals used by QEMU itself internally. The wrapper is called from all the guest-initiated sigprocmask, but is not called from internal qemu sigprocmask calls.

However it's convenient for QEMU to use it to hold the various PSTATE architectural bits in the same format the architecture specifies for SPSR registers (since this is the same format the kernel uses for signal handlers and the KVM register).
