2010-02-18net: TCP thin linear timeoutsAndreas Petlund3-1/+34
This patch will make TCP use only linear timeouts if the stream is thin. This will help to avoid the very high latencies that thin stream suffer because of exponential backoff. This mechanism is only active if enabled by iocontrol or syscontrol and the stream is identified as thin. A maximum of 6 linear timeouts is tried before exponential backoff is resumed.

2010-02-17net: bug fix for vlan + gro issueAjit Khaparde1-1/+1
Traffic (tcp) doesnot start on a vlan interface when gro is enabled. Even the tcp handshake was not taking place. This is because, the eth_type_trans call before the netif_receive_skb in napi_gro_finish() resets the skb->dev to napi->dev from the previously set vlan netdev interface. This causes the ip_route_input to drop the incoming packet considering it as a packet coming from a martian source. I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7. With this fix, the traffic starts and the test runs fine on both vlan and non-vlan interfaces.

2010-02-16net neigh: Decouple per interface neighbour table controls from binary sysctlsEric W. Biederman5-11/+8
Stop computing the number of neighbour table settings we have by counting the number of binary sysctls. This behaviour was silly and meant that we could not add another neighbour table setting without also adding another binary sysctl. Don't pass the binary sysctl path for neighour table entries into neigh_sysctl_register. These parameters are no longer used and so are just dead code. Signed-off-by: Eric W.

2010-02-16netfilter: ebtables: try native set/getsockopt handlers, tooFlorian Westphal1-10/+24
ebtables can be compiled to perform userspace-side padding of structures. In that case, all the structures are already in the 'native' format expected by the kernel. This tries to determine what format the userspace program is using. For most set/getsockopts, this can be done by checking the len argument for sizeof(compat_ebt_replace) and re-trying the native handler on error. In case of EBT_SO_GET_ENTRIES, the native handler is tried first, it will error out early when checking the *len argument (the compat version has to defer this check until after iterating over the kernel data set once, to adjust for all the structure size differences). As this would cause error printks, remove those as well, as recommended by Bart de Schuymer. Signed-off-by: Florian Westphal <fw@strlen.de>

At least ebt_mark, m_mark and ebt_limit need CONFIG_COMPAT hooks, too. remaining problem: The ebtables userland makefile has: ifeq ($(shell uname -m),sparc64) CFLAGS+=-DEBT_MIN_ALIGN=8 -DKERNEL_64_USERSPACE_32 endif struct ebt_replace, ebt_entry_match etc. then contain userland-side padding, i.e. even if we are called from a 32 bit userland, the structures may already be in the right format.

2010-02-15cfg80211/mac80211: allow registering for and sending action framesJouni Malinen10-15/+534
This implements a new command to register for action frames that userspace wants to handle instead of the in-kernel rejection. It is then responsible for rejecting ones that it decided not to handle. There is no unregistration, but the socket can be closed for that. Frames that are not registered for will not be forwarded to userspace and will be rejected by the kernel, the cfg80211 API helps implementing that. Additionally, this patch adds a new command that allows doing action frame transmission from userspace. It can be used either to exchange action frames on the current operational channel (e.g., with the AP with which we are currently associated) or to exchange off-channel Public Action frames with the remain-on-channel command.
