eliminate duplicate recv(2) code
2020-11-16eliminate duplicate recv(2) codeThanos Makatos1-300/+182
Instead of having each command handler do its own recv(2) to receive the command, we do this once for all commands. This reduces the code a bit. Signed-off-by: Thanos Makatos <thanos.makatos@nutanix.com>
2020-11-16use object libraries to build libmuserJohn Levon1-2/+5
Using target_link_libraries for libmuser meant that unused symbols - including all of the public API - were not brought into the target shared object. Use CMake's "object library" feature instead, which doesn't use intermediate archives and thus avoids this issue.

2020-11-11drop the kernel moduleThanos Makatos4-475/+158
vfio-user is on track to be accepted upstream, so we shouldn't need muser.ko. This patch removes it since keeping it in the source is a maintanance burden. The last version is stashed in https://github.com/nutanix/muser/tree/kmod. If there is a valid use case we can reconsider reinstating it. fixes #67 Signed-off-by: Thanos Makatos <thanos.makatos@nutanix.com>

2020-10-29support for live migration region and dirty page loggingThanos Makatos6-149/+641
This patch adds support for the live migration region and dirty page logging following VFIO. Live migration is NOT yet functional as handling accesses to the migration region is not yet implemented. Currenty the live migration region is fixed at index 9 simply for simplifying the implementation. Dirty page logging is simplified by requiring IOVA ranges to match exactly the entire IOVA range.
