| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | broute table init hook sets up the "br_should_route_hook" pointer, which then gets called from br_input. commit a386f99025f13b32502fe5dedf223c20d7283826 (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.

| | * netfilter: fix race in conntrack between dump_table and destroyStephen Hemminger2011-01-111-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | * netfilter: x_tables: dont block BH while reading countersEric Dumazet2011-01-105-99/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: David 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
