[x86_64] Fix assorted 64-bit compilation errors and warnings

2008-11-19T19:33:05+00:00

Remove various 32-bit assumptions scattered throughout the codebase. The code is still not necessarily 64-bit clean, but will at least compile.

[i386] Change [u]int32_t to [unsigned] int, rather than [unsigned] long

2008-11-19T19:15:44+00:00

This brings us in to line with Linux definitions, and also simplifies adding x86_64 support since both platforms have 2-byte shorts, 4-byte ints and 8-byte long longs.

[TCP] Avoid shrinking TCP window

2008-06-04T23:28:17+00:00

Maintain state for the advertised window length, and only ever increase it (instead of calculating it afresh on each transmit). This avoids triggering "treason uncloaked" messages on Linux peers. Respond to zero-length TCP keepalives (i.e. empty data packets transmitted outside the window). Even if the peer wouldn't otherwise expect an ACK (because its packet consumed no sequence space), force an ACK if it was outside the window. We don't yet generate TCP keepalives. It could be done, but it's unclear what benefit this would have. (Linux, for example, doesn't start sending keepalives until the connection has been idle for two hours.)

Modify gPXE core and drivers to work with the new timer subsystem

Various warnings fixups for OpenBSD with gcc-3.3.5.

Use start_timer_nodelay() in protocols which rely on the retry timer

to generate the initial transmission; this cuts off around 0.3s per instantiated connection.

Add per-file error identifiers

Add support for TCP timestamps

Adjust received length to take into account any already-received data

in tcp_rx_data(). Clarify comments on discarding duplicate or out-of-order data.
