[Bug 1624014] [NEW] Wrong bit set in klibc PXE dhcp/bootp flags

[Launchpad Bug Tracker]

[Description]

The patch for bug 1327412 set the wrong bit in the bootp flags field.
It set flags to 0x800, but the correct value is 0x8000.  That sets the
"broadcast" bit, and the spec requires all other bits to be 0.

Setting one of the "must be zero" bits in the flags field causes some
DHCP relay agents to drop the packets, causing PXE to fail.

[Test Case]

Get a DHCP relay agent that drops PXE packets with an invalid
bootp.flags bit set, and try to PXE boot; it fails.

[Regression]

None, the previous patch introduced this regression.
