2015-06-11s390x/watchdog: introduce diag288 watchdog deviceXu Wang5-0/+151
This patch introduces a new diag288 watchdog device that will, just like other watchdogs, monitor a guest and take corresponding actions when it detects that the guest is not responding. diag288 is s390x specific. The wiring to s390x KVM will be done in separate patches.

4096 is the maximum length per TMD and it is also currently the size of the relay buffer pcnet driver uses for sending the packet data to QEMU for further processing. With packet spanning multiple TMDs it can happen that the overall packet size will be bigger than sizeof(buffer), which results in memory corruption. Fix this by only allowing to queue maximum sizeof(buffer) bytes. This is CVE-2015-3209.

It has been reported that sometimes the .rodata section of SeaBIOS, containing the constant string against which the SMBIOS signature ends up being compared, also falls within the guest f-segment. In that case, the test obviously fails, unless we continue searching for the *real* SMBIOS entry point. Rather than stopping at the first match for the SMBIOS signature ("_SM_") in the f-segment (0xF0000-0xFFFFF), continue scanning until either a valid entry point table is found, or the f-segment has been exhausted.

2015-06-09tcg: fix dead computation for repeated input argumentsAurelien Jarno1-3/+11
When the same temp is used twice or more as an input argument to a TCG instruction, the dead computation code doesn't recognize the second use as a dead temp. This is because the temp is marked as live in the same loop where dead inputs are checked. The fix is to split the loop in two parts. This avoid emitting a move and using a register for the movcond instruction when used as "move if true" on x86-64. This might bring more improvements on RISC TCG targets which don't have outputs aliased to inputs.

2015-06-09tcg: fix register allocation with two aliased dead inputsAurelien Jarno1-0/+10
For TCG ops with two outputs registers (add2, sub2, div2, div2u), when the same input temp is used for the two inputs aliased to the two outputs, and when these inputs are both dead, the register allocation code wrongly assigned the same register to the same output. This happens for example with sub2 t1, t2, t3, t3, t4, t5, when t3 is not used anymore after the TCG op. In that case the same register is used for t1, t2 and t3. The fix is to look for already allocated aliased input when allocating a dead aliased input and check that the register is not already used.

In HMP, they go to the monitor. In QMP, the last one becomes the error reply, and the others go to stderr. Convert net_init_vhost_user() and its helpers to Error.
