2020-09-23Handle cleanup in init_socket for error outSwapnil Ingle1-35/+39
This patch adds cleanup during error out in init_socket. Also no need to create control socket path, bind() on AF_UNIX creates the path internally. Signed-off-by: Swapnil Ingle <swapnil.ingle@nutanix.com>

2020-07-17refactor PCI capabilitiesThanos Makatos4-204/+140
This patch greatly refactors PCI capabilities. The main change is that we don't keep them in a list but simply store them in the PCI configuration space. Some corner cases aren't handled yet. It also fixes a bug where a capability isn't properly read depending on where it's located. Signed-off-by: Thanos Makatos <thanos.makatos@nutanix.com>

2020-07-09minor improvements in non-blocking receive pathThanos Makatos1-15/+13
Signed-off-by: Thanos Makatos <thanos.makatos@nutanix.com>
2020-07-09Use MSG_DONTWAIT to receive requests if LM_FLAG_ATTACH_NB is specifiedBen Walker1-1/+18
If the user wanted non-blocking operation, don't block on the socket waiting for requests. Instead, use MSG_DONTWAIT to attempt to get the next request and return. The other operations all remain as blocking calls because they are not expected to ever need to wait. Signed-off-by: Ben Walker <benjamin.walker@intel.com>
2020-07-09All transport operations now take an lm_ctx_t as an argumentBen Walker1-23/+36
This is both for consistency and because the socket transport is going to need some place to cache things to handle partial sends and receives. Signed-off-by: Ben Walker <benjamin.walker@intel.com>

2020-07-08dma: notify device of DMA removal eventsThanos Makatos4-39/+106
This patch introduces a new device callback that is called when a DMA region is removed. The device must provide this callback and when the callback returns all references to the DMA regions must have been removed. This new functionality is necessary since a DMA region can be removed at any time, so the device must be given a chance to drop all references and perform the necessary cleanup. This patch also stores lm_ctx_t inside dma_controller_t so that we don't have to pass lm_ctx_t when calling dma_XXX functions. Signed-off-by: Thanos Makatos <thanos.makatos@nutanix.com>

2020-07-08Add lm_ctx_poll() as an alternative to lm_ctx_drive()Ben Walker2-53/+82
Using lm_ctx_poll() simply polls for work and returns instead of blocking. It is only valid when used on an lm_ctx created with LM_FLAG_ATTACH_NB. Signed-off-by: Ben Walker <benjamin.walker@intel.com>
2020-07-08Drop __attribute__((packed))from struct lm_ctxBen Walker1-13/+4
This makes it unsafe to take pointers to addresses within this data structure, and lots of the code does that. Signed-off-by: Ben Walker <benjamin.walker@intel.com>

2020-06-12muser: use the correct PCI_COMMAND interrupt disable(ID) bitChangpeng Liu2-15/+2
When PCI_COMMAND interrupt disable bit set to 1, it means disable the pin-based INTx interrupt. For NVMe controller, it will use INTx first, and then switch to MSIX, the interrupt vector 0 is both valid for INTx and MSIX, so here we remove the check when posting an interrupt, just check the interrupt fd is valid or not.
