By the time that check is done, the socket will already have\nbeen passed to kernel_setsockopt. Move the check into smb_send_rqst, so\nthat it\u0027s checked earlier.\n\nIn truth, this is a bit of a half-assed fix. The -ENOTSOCK error\nreturn here looks like it could bubble back up to userspace. The locking\nrules around the ssocket pointer are really unclear as well. There are\ncases where the ssocket pointer is changed without holding the srv_mutex,\nbut I\u0027m not clear whether there\u0027s a potential race here yet or not.\n\nThis code seems like it could benefit from some fundamental re-think of\nhow the socket handling should behave.
