[Qemu-devel] [PATCH v4 0/3] restrict bridge interface name to IFNAMSIZ

[P J P]

From: Prasad J Pandit <address@hidden>

Hello,

Linux net_deivce defines network interface name to be of IFNAMSIZE(=16)
bytes, including the terminating null('\0') byte.

Qemu tap deivce, while invoking 'qemu-bridge-helper' tool to set up the
network bridge interface, supplies bridge name of 16 characters, thus
allowing to create an ACL bypass scenario.

This patch series attempts to fix it. It also updates bridge helper
invocation routine 'net_bridge_run_helper' to avoid snprintf() calls.

Thank you.
