2024-12-14	vsock/test: fix parameter types in SO_VM_SOCKETS_* calls	Konstantin Shkolnyy
	[ Upstream commit 3f36ee29e732b68044d531f47d31f22d265954c6 ] Change parameters of SO_VM_SOCKETS_* to unsigned long long as documented in the vm_sockets.h, because the corresponding kernel code requires them to be at least 64-bit, no matter what architecture. Otherwise they are too small on 32-bit machines.

2024-12-14	vsock/test: fix failures due to wrong SO_RCVLOWAT parameter	Konstantin Shkolnyy
	[ Upstream commit 7ce1c0921a806ee7d4bb24f74a3b30c89fc5fb39 ] This happens on 64-bit big-endian machines. SO_RCVLOWAT requires an int parameter. However, instead of int, the test uses unsigned long in one place and size_t in another. Both are 8 bytes long on 64-bit machines. The kernel, having received the 8 bytes, doesn't test for the exact size of the parameter, it only cares that it's >= sizeof(int), and casts the 4 lower-addressed bytes to an int, which, on a big-endian machine, contains 0. 0 doesn't trigger an error, SO_RCVLOWAT returns with success and the socket stays with the default SO_RCVLOWAT = 1, which results in vsock_test failures, while vsock_perf doesn't even notice that it's failed to change it.

	To use this option pass '--zerocopy' parameter: ./vsock_perf --zerocopy --sender <cid> ... With this option MSG_ZEROCOPY flag will be passed to the 'send()' call.
