msix: Assert that specified vector is in range

2022-11-07T19:08:17+00:00

There were several different ways to deal with the situation where the vector specified for a msix function is out of bound: - early return a function and keep progresssing - propagate the error to the caller - mark msix unusable - assert it is in bound - just ignore An out-of-bound vector should not be specified if the device implementation is correct so let msix functions always assert that the specified vector is in range. An exceptional case is virtio-pci, which allows the guest to configure vectors. For virtio-pci, it is more appropriate to introduce its own checks because it is sometimes too late to check the vector range in msix functions.

Use g_new() & friends where that makes obvious sense

2022-10-03T22:10:11+00:00

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). Patch created mechanically with: $ spatch --in-place --sp-file scripts/coccinelle/use-g_new-etc.cocci \ --macro-file scripts/cocci-macro-file.h FILES... The previous iteration was commit a95942b50c.
