2015-02-16Convert ram_list to RCUMike Day
Allow "unlocked" reads of the ram_list by using an RCU-enabled QLIST. The ramlist mutex is kept. call_rcu callbacks are run with the iothread lock taken, but that may change in the future. Writers still take the ramlist mutex, but they no longer need to assume that the iothread lock is taken. Readers of the list, instead, no longer require either the iothread or ramlist mutex, but they need to use rcu_read_lock() and rcu_read_unlock(). One place in arch_init.c was downgrading from write side to read side like this: qemu_mutex_lock_iothread() qemu_mutex_lock_ramlist() ... qemu_mutex_unlock_iothread() ... qemu_mutex_unlock_ramlist() and the equivalent idiom is: qemu_mutex_lock_ramlist() rcu_read_lock() ... qemu_mutex_unlock_ramlist() ... rcu_read_unlock() Reviewed-by: Fam Zheng <famz@redhat.com> Signed-off-by: Mike Day <ncmike@ncultra.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2014-11-18migration: fix parameter validation on ram loadMichael S. Tsirkin
During migration, the values read from migration stream during ram load are not validated. Especially offset in host_from_stream_offset() and also the length of the writes in the callers of said function. To fix this, we need to make sure that the [offset, offset + length] range fits into one of the allocated memory regions. Validating addr < len should be sufficient since data seems to always be managed in TARGET_PAGE_SIZE chunks. Fixes: CVE-2014-7840 Note: follow-up patches add extra checks on each block->host access.

2014-05-05Count used RAMBlock pages for migration_dirty_pagesDr. David Alan Gilbert
This is a fix for a bug* triggered by a migration after hot unplugging a few virtio-net NICs, that caused migration never to converge, because 'migration_dirty_pages' is incorrectly initialised. 'migration_dirty_pages' is used as a tally of the number of outstanding dirty pages, to give the migration code an idea of how much more data will need to be transferred, and thus whether it can end the iterative phase. It was initialised to the total size of the RAMBlock address space, however hotunplug can leave this space sparse, and hence migration_dirty_pages ended up too large.

2013-11-19migration: drop MADVISE_DONT_NEED for incoming zero pagesPeter Lieven
The madvise for zeroed out pages was introduced when every transferred zero page was memset to zero and thus allocated. Since commit 211ea740 we check for zeroness of a target page before we memset it to zero. Additionally we memmap target memory so it is essentially zero initialized (except for e.g. option roms and bios which are loaded into target memory although they shouldn't). It was reported recently that this madvise causes a performance degradation in some situations. As the madvise should only be called rarely and if it's called it is likely on a busy page (it was non-zero and changed to zero during migration) drop it completely.

2013-09-28smbios: Make multiple -smbios type= accumulate sanelyMarkus Armbruster
Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with value VAL to fw_cfg for each unique NAME. If NAME occurs multiple times, the last one's VAL is used (before the QemuOpts conversion, the first one was used). Multiple -smbios can add multiple fields with the same (T, NAME). SeaBIOS reads all of them from fw_cfg, but uses only the first field (T, NAME). The others are ignored. "First one wins, subsequent ones get ignored silently" isn't nice. We commonly let the last option win. Useful, because it lets you -readconfig first, then selectively override with command line options. Clean up -smbios to work the common way. Accumulate the settings, with later ones overwriting earlier ones. Put the result into fw_cfg (no more useless duplicates).
