Replace the global variables with inlined helper functions. getpagesize() is very likely annotated with a "const" function attribute (at least with glibc), and thus optimization should apply even better. This avoids the need for a constructor initialization too.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).

2021-09-30hostmem: Add hostmem-epc as a backend for SGX EPCSean Christopherson2-0/+83
EPC (Enclave Page Cahe) is a specialized type of memory used by Intel SGX (Software Guard Extensions). The SDM desribes EPC as: The Enclave Page Cache (EPC) is the secure storage used to store enclave pages when they are a part of an executing enclave. For an EPC page, hardware performs additional access control checks to restrict access to the page. After the current page access checks and translations are performed, the hardware checks that the EPC page is accessible to the program currently executing. Generally an EPC page is only accessed by the owner of the executing enclave or an instruction which is setting up an EPC page. Because of its unique requirements, Linux manages EPC separately from normal memory. Similar to memfd, the device /dev/sgx_vepc can be opened to obtain a file descriptor which can in turn be used to mmap() EPC memory.

2021-09-27qapi: Convert simple union TpmTypeOptions to flat oneMarkus Armbruster2-2/+2
Simple unions predate flat unions. Having both complicates the QAPI schema language and the QAPI generator. We haven't been using simple unions in new code for a long time, because they are less flexible and somewhat awkward on the wire. To prepare for their removal, convert simple union TpmTypeOptions to an equivalent flat one, with existing enum TpmType replacing implicit enum TpmTypeOptionsKind. Adds some boilerplate to the schema, which is a bit ugly, but a lot easier to maintain than the simple union feature.

2021-06-15hostmem: Wire up RAM_NORESERVE via "reserve" propertyDavid Hildenbrand4-5/+44
Let's provide a way to control the use of RAM_NORESERVE via memory backends using the "reserve" property which defaults to true (old behavior). Only Linux currently supports clearing the flag (and support is checked at runtime, depending on the setting of "/proc/sys/vm/overcommit_memory"). Windows and other POSIX systems will bail out with "reserve=false". The target use case is virtio-mem, which dynamically exposes memory inside a large, sparse memory area to the VM. This essentially allows avoiding to set "/proc/sys/vm/overcommit_memory == 0") when using virtio-mem and also supporting hugetlbfs in the future. As really only Linux implements RAM_NORESERVE right now, let's expose the property only with CONFIG_LINUX. Setting the property to "false" will then only fail in corner cases -- for example on very old kernels or when memory overcommit was completely disabled by the admin.

When management applications (like Libvirt) want to check whether memory-backend-file.pmem is supported they can list object properties using 'qom-list-properties'. However, 'pmem' is declared always (and thus reported always) and only at runtime QEMU errors out if it was built without libpmem (and thus can not guarantee write persistence).

2021-02-08confidential guest support: Introduce new confidential guest support classDavid Gibson2-0/+34
Several architectures have mechanisms which are designed to protect guest memory from interference or eavesdropping by a compromised hypervisor. AMD SEV does this with in-chip memory encryption and Intel's TDX can do similar things. POWER's Protected Execution Framework (PEF) accomplishes a similar goal using an ultravisor and new memory protection features, instead of encryption. To (partially) unify handling for these, this introduces a new ConfidentialGuestSupport QOM base class. "Confidential" is kind of vague, but "confidential computing" seems to be the buzzword about these schemes, and "secure" or "protected" are often used in connection to unrelated things (such as hypervisor-from-guest or guest-from-guest security). The "support" in the name is significant because in at least some of the cases it requires the guest to take specific actions in order to protect itself from hypervisor eavesdropping.

2021-02-01memory: add readonly support to memory_region_init_ram_from_file()Stefan Hajnoczi1-1/+1
There is currently no way to open(O_RDONLY) and mmap(PROT_READ) when creating a memory region from a file. This functionality is needed since the underlying host file may not allow writing. Add a bool readonly argument to memory_region_init_ram_from_file() and the APIs it calls. Extend memory_region_init_ram_from_file() rather than introducing a memory_region_init_rom_from_file() API so that callers can easily make a choice between read/write and read-only at runtime without calling different APIs. No new RAMBlock flag is introduced for read-only because it's unclear whether RAMBlocks need to know that they are read-only. Pass a bool readonly argument instead. Both of these design decisions can be changed in the future. It just seemed like the simplest approach to me.

2020-09-18qom: Remove ParentClassType argument from OBJECT_DECLARE_SIMPLE_TYPEEduardo Habkost2-3/+1
The requirement to specify the parent class type makes the macro harder to use and easy to misuse (silent bugs can be introduced if the wrong struct type is specified). Simplify the macro by just not declaring any class struct, allowing us to remove the class_size field from the TypeInfo variables for those types.
