Willy Tarreau [Wed, 14 Jan 2009 00:04:36 +0000 (16:04 -0800)]
tcp: splice as many packets as possible at once

As spotted by Willy Tarreau, current splice() from tcp socket to pipe is not
optimal. It processes at most one segment per call.
This results in low performance and very high overhead due to syscall rate
when splicing from interfaces which do not support LRO.

Willy provided a patch inside tcp_splice_read(), but a better fix
is to let tcp_read_sock() process as many segments as possible, so
that tcp_rcv_space_adjust() and tcp_cleanup_rbuf() are called less
often.

With this change, splice() behaves like tcp_recvmsg(), being able
to consume many skbs in one system call. With typical 1460 bytes
of payload per frame, that means splice(SPLICE_F_NONBLOCK) can return
16*1460 = 23360 bytes.

since the PPPOE peer may require the padding to be present).

Therefore we should disable this by default.

It does mean that people relying on this feature may lose networking

However, IMHO the problems this code causes are serious enough to

15 years agominstrel: fix warning if lowest supported rate index is not 0

minstrel: fix warning if lowest supported rate index is not 0

This patch fixes the following WARNING (caused by rix_to_ndx): "
>WARNING: at net/mac80211/rc80211_minstrel.c:69 minstrel_rate_init+0xd2/0x33a [mac80211]()

The reason is that I'm experimenting with "g" only mode on a 802.11 b/g card.

Therefore rate_lowest_index returns 4 (= 6Mbit, instead of usual 0 = 1Mbit).
Since mi->r array is initialized with zeros in minstrel_alloc_sta,
rix_to_ndx has a hard time to find the 6Mbit entry and will trigged the WARNING.

rt2x00: Fix segementation fault

The queue_end() macro points to 1 position after the

is at the end of the queue we should first increment
the position and then check if it is a valid entry.

This fixes a segmentation fault which only occurs when
the device has enough endpoints to provide a dedicated

for rt2500usb and rt73usb, but will happen for rt2800usb).
