broute table init hook sets up the "br_should_route_hook" pointer, which then gets called from br_input. commit a386f990 (bridge: add proper RCU annotation to should_route_hook) introduced a typedef, and then changed this to: br_should_route_hook_t *rhook; [..] rhook = rcu_dereference(br_should_route_hook); if (*rhook(skb)) problem is that "br_should_route_hook" contains the address of the function, so calling *rhook() results in kernel panic.

The netlink interface to dump the connection tracking table has a race when entries are deleted at the same time. A customer reported a crash and the backtrace showed thatctnetlink_dump_table was running while a conntrack entry was being destroyed. (see https://bugzilla.vyatta.com/show_bug.cgi?id=6402). According to RCU documentation, when using hlist_nulls the reader must handle the case of seeing a deleted entry and not proceed further down the linked list. The old code would continue which caused the scan to walk into the free list. This patch uses locking (rather than RCU) for this operation which is guaranteed safe, and no longer requires getting reference while doing dump operation.

inet_csk_bind_conflict() logic currently disallows a bind() if it finds a friend socket (a socket bound on same address/port) satisfying a set of conditions : 1) Current (to be bound) socket doesnt have sk_reuse set OR 2) other socket doesnt have sk_reuse set OR 3) other socket is in LISTEN state We should add the CLOSE state in the 3) condition, in order to avoid two REUSEADDR sockets in CLOSE state with same local address/port, since this can deny further operations. Note : a prior patch tried to address the problem in a different (and buggy) way. (commit fda48a0d tcp: bind() fix when many ports are bound).

IPv4 over firewire needs to be able to remove ARP entries from the ARP cache that belong to nodes that are removed, because IPv4 over firewire uses ARP packets for private information about nodes. This information becomes invalid as soon as node drops off the bus and when it reconnects, its only possible to start talking to it after it responded to an ARP packet. But ARP cache prevents such packets from being sent. Signed-off-by: NMaxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

For the VFs, the Mailbox Data "registers" are actually backed by T4's "MA" interface rather than PL Registers (as is the case for the PFs). Because these are in different coherency domains, the write to the VF's PL-register-backed Mailbox Control can race in front of the writes to the MA-backed VF Mailbox Data "registers". So we need to do a read-back on at least one byte of the VF Mailbox Data registers before doing the write to the VF Mailbox Control register.

Using "iptables -L" with a lot of rules have a too big BH latency. Jesper mentioned ~6 ms and worried of frame drops. Switch to a per_cpu seqlock scheme, so that taking a snapshot of counters doesnt need to block BH (for this cpu, but also other cpus). This adds two increments on seqlock sequence per ipt_do_table() call, its a reasonable cost for allowing "iptables -L" not block BH processing.

This change fixes several issues found in ntuple filtering while I was doing the ATR refactor. Specifically I updated the masks to work correctly with the latest version of ethtool, I cleaned up the exception handling and added detailed error output when a filter is rejected, and corrected several bits that were set incorrectly in ixgbe_type.h. The previous version of this patch included a printk that was left over from me fixing the filter setup. This patch does not include that printk.

This change adds a compressed input type for atr signature hash computation. It also drops the use of the set functions when setting up the ATR input since we can then directly setup the hash input as two dwords that can be stored and passed as registers. With these changes the cost of computing the has is low enough that we can perform a hash computation on each TCP SYN flagged packet allowing us to drop the number of flow director misses considerably in tests such as netperf TCP_CRR.

This change cleans up the layout of the flow director data, and the algorithm used to calculate the hash resulting in a 35x / 3500% performance increase versus the old flow director hash computation. The overall effect is only a 1% increase in transactions per second though due to the fact that only 1 packet in 20 are actually hashed upon. TCP_RR before: Socket Size Request Resp. Elapsed Trans.

Some Phys supported by the driver do not remain powered off across a reset of the device when the interface is down, e.g. on 82571, but not on 82574. This patch powers down (only when WoL is disabled) the PHY after a reset if the interface is down and the ethtool diagnostics are not currently running. The ethtool diagnostic function required a minor re-factor as a result, and the e1000_[get|put]_hw_control() functions are renamed since they are no longer static to netdev.c as they are needed by the ethtool diagnostics. A couple minor whitespace issues were cleaned up, too.
