Throw out the old mark & sweep garbage collector and put in a refcounting cycle detecting one. The old one had a race with recvmsg, that resulted in false positives and hence data loss. The old algorithm operated on all unix sockets in the system, so any additional locking would have meant performance problems for all users of these. The new algorithm instead only operates on "in flight" sockets, which are very rare, and the additional locking for these doesn't negatively impact the vast majority of users. In fact it's probable, that there weren't *any* heavy senders of sockets over sockets, otherwise the above race would have been discovered long ago. The patch works OK with the app that exposed the race with the old code. The garbage collection has also been verified to work in a few simple cases.

When creating a new connection by sending an unknown chunk type, we don't transition to a valid state, causing a NULL pointer dereference in sctp_packet when accessing sctp_timeouts[SCTP_CONNTRACK_NONE]. Fix by don't creating new conntrack entry if initial state is invalid.

The "fix" for emerging security threat was overkill and it broke basic semantic of IPv6 routing header processing. We should assume RT0 (or even RT2, depends on configuration) as "unknown" RH type so that we - silently ignore the routing header if segleft == 0 - send ICMPv6 Parameter Problem message back to the sender, otherwise.

93ec2c72 applied excessive duct tape to the netpoll beast's netpoll_cleanup(), thus substituting one leak with another, and opening up a little buglet :-) net_device->npinfo (netpoll_info) is a shared and refcounted object and cannot simply be set NULL the first time netpoll_cleanup() is called. Otherwise, further netpoll_cleanup()'s see np->dev->npinfo == NULL and become no-ops, thus leaking. And it's a bug too: the first call to netpoll_cleanup() would thus (annoyingly) "disable" other (still alive) netpolls too. Maybe nobody noticed this because netconsole (only user of netpoll) never supported multiple netpoll objects earlier. This is a trivial and obvious one-line fixlet.

Document the expectations about device MTU handling. The documentation about oversize packet handling is probably too loose. IMHO devices should drop oversize packets for robustness, but many devices allow it now. For example, if you set mtu to 1200 bytes, most ether devices will allow a 1500 byte frame in.

In addition to the periodic heartbeat, we're adding a heartbeat request interrupt when the heartbeat is late. This is needed during netpoll where the timer is not available. -rt kernels will also benefit since the timer is not as accurate. [ We discussed this patch last time and we decided that the -rt kernel problem alone did not justify this patch. I think the netpoll problem makes this patch necessary. ] Signed-off-by: NMichael Chan <mchan@broadcom.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Spurious interrupts are often encountered especially on systems using the 8259 PIC mode. This is because the I/O write to deassert the interrupt is posted and won't get to the chip immediately. As a result, the IRQ may remain asserted after the IRQ handler exits, causing spurious interrupts. Add read back to flush the I/O write to deassert the IRQ immediately. We also store the last_status_idx immediately in the IRQ handler to help detect whether the interrupt is ours or not when the IRQ is entered again before ->poll gets called.

In blade servers, the Serdes PHY in 5708S can control the remote copper PHY through autonegotiation on the backplane. This patch adds the logic to interface with the firmware to control the remote PHY autonegotiation and to handle remote PHY link events. When remote PHY is present, the 5708S Serdes device practically becomes a copper device with full control over the 1000Base-T link settings.
