Subject: [patch] vsock.7: Add missing structure element
Date: Tue, 19 Nov 2019 18:31:34 +0100	[thread overview]
Message-ID: <20191119173134.5668-1-Mikhail.Golubev@opensynergy.com> (raw)

The structure 'struct sockaddr_vm' has additional element 'unsigned char
svm_zero[]' since version v3.9-rc1 (include/uapi/linux/vm_sockets.h).
Linux kernel checks that this element is zeroed
(net/vmw_vsock/vsock_addr.c). Reflect this on the vsock man page.

Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=205583
