MFC r216758,217252:
- Add some helper hook points to the TCP stack. The hooks allow Khelp modules
to
access inbound/outbound events and associated data for established TCP
connections. The hooks only run if at least one hook function is registered
for the hook point, ensuring the impact on the stack is effectively nil when
no TCP Khelp modules are loaded. struct tcp_hhook_data is passed as
contextual
data to any registered Khelp module hook functions.
- Add an OSD (Object Specific Data) pointer to struct tcpcb to allow Khelp
modules to associate per-connection data with the TCP control block.
- Tweak the MFCed code to preserve the ABI of the 8-STABLE branch with respect
to "struct tcpcb" by consuming some of the padding within the struct.
- Bump __FreeBSD_version to 802506.

ERTT uses the Khelp/Hhook KPIs to hook into the TCP stack and maintain a per-connection, low noise estimate of the instantaneous RTT. ERTT's implementation is robust even in the face of delayed acknowledgements and/or TSO being in use for a connection. A high quality, low noise RTT estimate is a requirement for applications such as delay-based congestion control, for which we will be importing some algorithm implementations shortly.

VEGAS uses network delay as a congestion indicator and unlike regular loss-based algorithms, attempts to keep the network operating with stable queuing delays and no congestion losses. By keeping network buffers used along the path within a set range, queuing delays are kept low while maintaining high throughput.

It is implemented as a kernel module compatible with the recently committed modular congestion control framework. HD uses a probabilistic approach to reacting to delay-based congestion. The probability of reducing cwnd is zero when the queuing delay is very small, increasing to a maximum at a set threshold, then back down to zero again when the queuing delay is high. Normal operation keeps the queuing delay below the set threshold. However, since loss-based congestion control algorithms push the queuing delay high when probing for bandwidth, having the probability of reducing cwnd drop back to zero for high delays allows HD to compete with loss-based algorithms.

It is implemented as a kernel module compatible with the recently committed modular congestion control framework. CHD enhances the approach taken by the Hamilton-Delay (HD) algorithm to provide tolerance to non-congestion related packet loss and improvements to coexistence with loss-based congestion control algorithms. A key idea in improving coexistence with loss-based congestion control algorithms is the use of a shadow window, which attempts to track how NewReno's congestion window (cwnd) would evolve. At the next packet loss congestion event, CHD uses the shadow window to correct cwnd in a way that reduces the amount of unfairness CHD experiences when competing with loss-based algorithms.

svn commit: r222418 - in head: tools/regression/usr.bin/printf usr.bin/printf
Author: jilles
Date: Sat May 28 11:37:47 2011
New Revision: 222418
URL: http://svn.freebsd.org/changeset/base/222418
Log:
printf: Allow multibyte characters for ' form, avoid negative codes.
Examples:
LC_ALL=en_US.UTF-8 printf '%d\n' $(printf \'\\303\\244)
LC_ALL=en_US.ISO8859-1 printf '%d\n' $(printf \'\\344)
Both of these should print 228.
Like some other shells, incomplete or invalid multibyte characters yield the
value of the first byte without a warning.
Note that there is no general way to go back from the character code to the
character.

svn commit: r222432 - in head/sys/dev/ath: . ath_hal/ar9002

New Revision: 222432

Log:
Teach if_ath about devices which have short-GI in 20MHz channel modes.
This has been disabled until now because there hasn't been any supported
device which has this feature. Since the AR9287 is the first device to
support it, and since now the HAL has functional AR9287+11n support,
flip this on.

Log:
o Add system versions for the P4040(E) and P4080(E).
o In bare_probe(), change the logic that determines the maximum
number of processors/cores into a switch statement and take
advantage of the fact that bit 3 of the SVR value indicates
whether we're running on a security enabled version. Since we
don't care about that here, mask the bit. All -E versions
are taken care of automatically.

We could, but I'm not sure I should be concerned about the "scaling" of the various arrays in the kernel due to MAXCPU. This with an eye on small embedded devices that do 2-way SMP. I've never liked this constant anyway to be honest. It's either too big or too small. I don't think it'll ever be right :-) -- Marcel Moolenaar mar...@xcllnt.net ___ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
