Subject: [PATCH 10/12] net: socket: remove net_init_socket()
|
|
|
|
RH-Author: Laurent Vivier <lvivier@redhat.com>
|
|
RH-MergeRequest: 187: net: socket: do not close file descriptor if it's not a socket
|
|
RH-Jira: RHEL-582

RH-Commit: [3/3] e1d7939f5df4a77c2fff62d1ae4899a7a3615ad9 (lvivier/qemu-kvm-centos)
|
|
|
|
JIRA: https://issues.redhat.com/browse/RHEL-582
|
|
|
|
Move the file descriptor type checking before doing anything with it.
|
|
If it's not usable, don't close it as it could be in use by another
|
|
part of QEMU, only fail and report an error.
