[PATCH v2 0/2] Some trivial live update fixes

Posted by Zhenzhong Duan 4 months, 3 weeks ago

Hi

These are trivial VFIO live update fixes in corner cases.

1) potential SIGSEGV when unmap-all-vaddr failed
2) potential vfio_container_post_load failure

Thanks
Zhenzhong

Changelog:
v2:
- drop patch1,2 in v1 as they are merged
- squashed "local save" parts of patch3 into patch4 (Steve)
- s/DMA_MAP_FUNC/dma_map_fn (Steve)

Zhenzhong Duan (2):
  vfio/container: Fix potential SIGSEGV when recover from
    unmap-all-vaddr failure
  vfio/container: Fix vfio_container_post_load()
