2015-04-02hw/arm/vexpress: Don't double-free flash filenamePeter Maydell
Commits 6e05a12f8f7f and db25a1581 both attempt to fix the same "failed to free memory containing flash filename" bug, with the effect that when they were both applied we ended up freeing the memory twice. Delete the spurious extra free.

2015-04-01target-arm: kvm64 fix save/restore of SPSR regspull-target-arm-20150401Alex Bennée
The current code was negatively indexing the cpu state array and not synchronizing banked spsr register state with the current mode's spsr state, causing occasional failures with migration. Some munging is done to take care of the aarch64 mapping and also to ensure the most current value of the spsr is updated to the banked registers (relevant for KVM<->TCG migration).

2015-04-01CVE-2015-1779: limit size of HTTP headers from websockets clientsDaniel P. Berrange
The VNC server websockets decoder will read and buffer data from websockets clients until it sees the end of the HTTP headers, as indicated by \r\n\r\n. In theory this allows a malicious to trick QEMU into consuming an arbitrary amount of RAM. In practice, because QEMU runs g_strstr_len() across the buffered header data, it will spend increasingly long burning CPU time searching for the substring match and less & less time reading data. So while this does cause arbitrary memory growth, the bigger problem is that QEMU will be burning 100% of available CPU time. A novnc websockets client typically sends headers of around 512 bytes in length. As such it is reasonable to place a 4096 byte limit on the amount of data buffered while searching for the end of HTTP headers. Signed-off-by: Daniel P. Berrange <berrange@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2015-04-01CVE-2015-1779: incrementally decode websocket framesDaniel P. Berrange
The logic for decoding websocket frames wants to fully decode the frame header and payload, before allowing the VNC server to see any of the payload data. There is no size limit on websocket payloads, so this allows a malicious network client to consume 2^64 bytes in memory in QEMU. It can trigger this denial of service before the VNC server even performs any authentication. The fix is to decode the header, and then incrementally decode the payload data as it is needed. With this fix the websocket decoder will allow at most 4k of data to be buffered before decoding and processing payload. Signed-off-by: Daniel P.

2015-04-01rcu: do not create thread in pthread_atfork callbackPaolo Bonzini
If QEMU forks after the CPU threads have been created, qemu_mutex_lock_iothread will not be able to do qemu_cpu_kick_thread. There is no solution other than assuming that forks after the CPU threads have been created will end up in an exec. Forks before the CPU threads have been created (such as -daemonize) have to call rcu_after_fork manually. Notably, the oxygen theme for GTK+ forks and shows a "No such process" error without this patch. This patch can be reverted once the iothread loses the "kick the TCG thread" magic. User-mode emulation does not use the iothread, so it can also call rcu_after_fork.

2015-03-26seccomp: libseccomp version varying according to archEduardo Otubo
Libseccomp dependency was mandating version 2.2.0 on all architectures and this was causing configure and virt-test to break on non-updates distros. This patch works-around it and give a more flexible way to check the version, giving more time for other distros to update libseccomp version.

2015-03-26migration: remove last_sent_block from save_page_headerJuan Quintela
Compression code (still not on tree) want to call this funtion from outside the migration thread, so we can't write to last_sent_block. Instead of reverting full patch: [PULL 07/11] save_block_hdr: we can recalculate Just revert the parts that touch last_sent_block.
