2018-10-24vlib: Fix pci io bar read/write fd leakMohsin Kazmi1-0/+6
Few devices provide PCI bar region(s) through I/O. If any such device driver opens I/O "fd" to read and write, needs to close it, when pci device is going to be deleted. Change-Id: Iba104e56f76c6bf9ccd27bf2223bad39b1301763 Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>

2018-06-27gcc8 and Wstringop-truncationMarco Varlese1-2/+4
gcc8 introduced a new warning (Wstringop-truncation) which in our case is being treated as error. Disabling the warning globally might introduce bugs related to string truncation which are not desired by the developer (e.g. bug). Instead, this patch disables the warning only for those occurences which have been verified to be non-bugs but the desired behaviour as per developer will.
