This adds handling of MSG_ERRQUEUE input flag in receive call. This flag is used to read socket's error queue instead of data queue. Possible scenario of error queue usage is receiving completions for transmission with MSG_ZEROCOPY flag. This patch also adds new defines: 'SOL_VSOCK' and 'VSOCK_RECVERR'. Signed-off-by: Arseniy Krasnov <avkrasnov@xxxxxxxxxxxxxxxxx> --- Changelog: v1 -> v2: * Place new defines for userspace to the existing file 'vm_sockets.h' instead of creating new one. v2 -> v3: * Add comments to describe 'SOL_VSOCK' and 'VSOCK_RECVERR' in the file 'vm_sockets.h'. * Reorder includes in 'af_vsock.c' in alphabetical order. v3 -> v4: * Update comments for 'SOL_VSOCK' and 'VSOCK_RECVERR' by adding more details. include/linux/socket.h | 1 + include/uapi/linux/vm_sockets.h | 17 +++++++++++++++++ net/vmw_vsock/af_vsock.c | 6 ++++++ 3 files changed, 24 insertions(+)
