2013-04-05tcg-s390: Fix merge error in tgen_brcondRichard Henderson1-1/+1
When the TCG condition codes were re-organized last year, we failed to update all of the "old-style" tests for unsigned. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-04-05tcg-s390: Use all 20 bits of the offset in tcg_out_memRichard Henderson1-4/+5
This can save one insn, if the constant has any bits in 32-63 set, but no bits in 21-31 set. It never results in more insns. Signed-off-by: Richard Henderson <rth@twiddle.net>

Since we're always in 64-bit mode, load address performs a full 64-bit add. Use that for 3-address addition, as well as for larger constant addends when we lack extended-immediates facility. Signed-off-by: Richard Henderson <rth@twiddle.net>

The code to load the high 64 bits assumed that the insn used to load the low 64 bits zero-extended. Enforce that.

2013-04-04acpi_table_add(): extract and reimplement internalsLaszlo Ersek1-121/+163
The new function acpi_table_install() installs any blob the caller passes in. In the next patches this function will be promoted from helper role to extern. Reimplementing the logic should make it easier to understand. It also removes a buffer overflow when has_header && cumulative_file_size < ACPI_TABLE_HDR_SIZE - ACPI_TABLE_PFX_SIZE (In that case the g_realloc() call in the read() loop used to shrink the "acpi_tables" array, causing an out-of-bounds read access when copying the header out of "acpi_tables".) The new code isn't more daring alignment-wise than its predecessor: "acpi_table_header" is packed, and the uint32_t fields are at offsets 6, 26, and 34.

2013-04-04qemu-char: Call fe_claim / fe_release when not using qdev chr propertiesHans de Goede12-7/+42
chardev-frontends need to explictly check, increase and decrement the avail_connections "property" of the chardev when they are not using a qdev-chardev-property for the chardev. This fixes things like: qemu-kvm -chardev stdio,id=foo -device isa-serial,chardev=foo \ -mon chardev=foo Working, where they should fail. Most of the changes here are due to old hardware emulation code which is using serial_hds directly rather then a qdev-chardev-property.

2013-04-03target-i386: Check for host features before filter_features_for_kvm()Eduardo Habkost1-3/+3
commit 5ec01c2e96910e1588d1a0de8609b9dda7618c7f broke "-cpu ..,enforce", as it has moved kvm_check_features_against_host() after the filter_features_for_kvm() call. filter_features_for_kvm() removes all features not supported by the host, so this effectively made kvm_check_features_against_host() impossible to fail. This patch changes the call so we check for host feature support before filtering the feature bits.

2013-04-03xen-mapcache: pass the right size argument to test_bitsHanweidong1-4/+22
Compute the correct size for test_bits(). qemu_get_ram_ptr() and qemu_safe_ram_ptr() will call xen_map_cache() with size is 0 if the requested address is in the RAM. Then xen_map_cache() will pass the size 0 to test_bits() for checking if the corresponding pfn was mapped in cache. But test_bits() will always return 1 when size is 0 without any bit testing. Actually, for this case, test_bits should check one bit. So this patch introduced a __test_bit_size which is greater than 0 and a multiple of XC_PAGE_SIZE, then test_bits can work correctly with __test_bit_size >> XC_PAGE_SHIFT as its size.

2013-04-02chardev: clear O_NONBLOCK on SCM_RIGHTS file descriptorsStefan Hajnoczi1-0/+3
When we receive a file descriptor over a UNIX domain socket the O_NONBLOCK flag is preserved. Clear the O_NONBLOCK flag and rely on QEMU file descriptor users like migration, SPICE, VNC, block layer, and others to set non-blocking only when necessary. This change ensures we don't accidentally expose O_NONBLOCK in the QMP API. QMP clients should not need to get the non-blocking state "correct". A recent real-world example was when libvirt passed a non-blocking TCP socket for migration where we expected a blocking socket. The source QEMU produced a corrupted migration stream since its code did not cope with non-blocking sockets.

2013-04-02net: ensure "socket" backend uses non-blocking fdsStefan Hajnoczi1-1/+6
There are several code paths in net_init_socket() depending on how the socket is created: file descriptor passing, UDP multicast, TCP, or UDP. Some of these support both listen and connect. Not all code paths set the socket to non-blocking. This patch addresses the file descriptor passing and UDP cases which were missing socket_set_nonblock(fd) calls. I considered moving socket_set_nonblock(fd) to a central location but it turns out the code paths are different enough to require non-blocking at different places.
