---|---|---|---|
1 | From: Eugenio Pérez <eperezma@redhat.com> | ||
1 | 2 | ||
3 | Next patch will skip the registering of dma maps that the vdpa device | ||
4 | rejects in the iova tree. We need to consider that here or we cause a | ||
5 | SIGSEGV accessing result. | ||

3 | Update colo-proxy.txt,add IOThread configuration. | 3 | If a map fails for whatever reason, it must not be saved in the tree. |
4 | Later we have to configure IOThread,if not COLO can not work. | 4 | Otherwise, qemu will try to unmap it in cleanup, leaving to more errors. |

3 | The rocker device still implements the old PCIDeviceClass .init() | 3 | It's convenient to call iova_tree_remove from a map returned from |
4 | instead of the new .realize(). All devices need to be converted to | 4 | iova_tree_find or iova_tree_find_iova. With the current code this is not |
5 | .realize(). | 5 | possible, since we will free it, and then we will try to search for it |
6 | again. | ||
6 | 7 | ||
7 | .init() reports errors with fprintf() and return 0 on success, negative | 8 | Fix it making accepting the map by value, forcing a copy of the |
8 | number on failure. Meanwhile, when -device rocker fails, it first report | 9 | argument. Not applying a fixes tag, since there is no use like that at |
9 | a specific error, then a generic one, like this: | 10 | the moment. |

15 | Now, convert it to .realize() that passes errors to its callers via its | ||

17 | the patch, effect like this: | ||

3 | When enabled the virtio-net-pci, guest network packet will | ||
4 | load the vnet_hdr. In COLO status, the primary VM's network | ||
5 | packet maybe redirect to another VM, it needs filter-redirect | ||
6 | enable the vnet_hdr flag at the same time, COLO-proxy will | ||
7 | correctly parse the original network packet. If have any | ||
8 | misconfiguration here, the vnet_hdr_len is wrong for parse | ||
9 | the packet, the data+offset will point to wrong place. | ||

4 | I/O registers, triggering a reentrancy bug. | ||
