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>

2020-08-12muser.ko: Update for Linux 5.8Felipe Franciosi3-63/+24
This fixes vfio.diff to apply cleanly on Linux 5.8 and renames vm_insert_pages to _vm_insert_pages because an upstream function of the same name has been added to the kernel since. Future work will include replacing our version of vm_insert_pages with the upstream and redo all necessary testing. We also update travis to use v5.8.

2020-08-12Split compilation unit of muser shared libraryFelipe Franciosi1-8/+19
This creates several smaller libraries out of the compilation units of the muser userspace library. It then links them together to build the shared library. In this process, we also generate unit test version of the libraries which include --coverage in the compilation and linking of those files. Those will be statically linked to unit tests later on.

2020-08-12Bounce pci_info with pci_info_bounce()Felipe Franciosi1-1/+23
During lm_ctx_create, the pci_info struct from dev_info was being completely copied with a big memcpy(). That had the side-effect of copying pointers that were not allocated by us. Shortly after, copy_sparse_mmap_areas() rewrites these pointers with memory allocated by the library. As a result, any failure half-way through setting up the context would result in free_sparse_mmap_areas() calling free() on pointers we did not allocate (which resulted in errors or double frees). This fixes it by replacing the memcpy() with pci_info_bounce() which selectively copies only what is needed. Signed-off-by: Felipe Franciosi <felipe@nutanix.com>
2020-08-12sparse_mmap: Free bounced areas on lm_ctx_destroyFelipe Franciosi1-9/+10
We were leaking the areas bounced by copy_sparse_mmap_areas(). This fixes the leak by freeing the areas on the destructor. Signed-off-by: Felipe Franciosi <felipe@nutanix.com>
2020-08-12dma: Cope with dma being NULL in destructorFelipe Franciosi1-0/+4
On certain error paths, @dma will be NULL. This makes the destructor cope with it. Signed-off-by: Felipe Franciosi <felipe@nutanix.com>
2020-08-12Rename libmuser*c source filesFelipe Franciosi3-4/+9
For clarity and better project organisation towards unit tests, this renames libmuser.c to muser_ctx.c and libmuser_pci.c to muser_pci.c. CMakeLists is fixed accordingly including some other minor cleanup. Future work should further split muser_ctx.c so that unit tests can genuinely be written towards testing compilation units.

2020-07-22muser: 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.

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>
