DOS ain't dead

mTCP 2010-09-16 Version (Announce)

Hi,

Just a quick note - I've posted a new version of mTCP at http://www.brutman.com/mTCP .

The biggest change is a bug fix. Some packet drivers refuse to send packets less than 60 bytes in size while many older packet drivers don't care. Technically speaking, a packet less than 60 bytes in size is invalid. I have fixed the code so that all of the packets meet the minimum.

Notably it was an Intel Gigabit Ethernet packet driver that exposed this bug. I have no idea how many other packet drivers check for 'runt' packets, but this might explain problems people have had with newer PCI cards.

And yes, I am embarrassed. Special thanks to Fred Macall for reporting the bug.

There are also some small performance fixes. The next release will be more substantial.


Regards,
Mike
