* mlx4_{core, ib, en}: Fix driver when sizeof (phys_addr_t) > sizeof (long)Roland Dreier2011-01-124-6/+8
| | | | | | | | | Some systems have PCI addresses that don't fit in unsigned long (eg some 32-bit PowerPC 440 systems have 36-bit bus addresses). Fix up mlx4 drivers by using phys_addr_t where appropriate, so we don't truncate any PCI resource addresses before ioremapping them. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/+49Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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 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.

| | | | | | | | | | | | | | | | | | | | | | Cleans up the code a bit by using the driver-specific e1e_rphy and e1e_wphy macros instead of the full function pointer variants. Fix a couple whitespace issue with two already existing calls to e1e_wphy.

| | | | | | | | | | | | | | | | | | | | | | | | | | The ICR register is clear on read and we don't care what the returned value is when resetting the hardware so the icr variable(s) can be removed. We should not ignore the return from e1000_lv_jumbo_workaround_ich8lan() and from e1000_get_phy_id_82571() (dump a debug message when it fails and when an unknown Phy id is returned).

| * net offloading: Convert checksums to use centrally computed features.Jesse Gross2011-01-101-28/+12Star
| | | | | | | | | | | | | | | | | | | | | | In order to compute the features for other offloads (primarily scatter/gather), we need to first check the ability of the NIC to offload the checksum for the packet. Since we have already computed this, we can directly use the result instead of figuring it out again. Signed-off-by: Jesse Gross <jesse@nicira.com> Signed-off-by: David S.

| * net offloading: Convert skb_need_linearize() to use precomputed features.Jesse Gross2011-01-101-15/+6Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This switches skb_need_linearize() to use the features that have been centrally computed. In doing so, this fixes a problem where scatter/gather should not be used because the card does not support checksum offloading on that type of packet. On device registration we only check that some form of checksum offloading is available if scatter/gatther is enabled but we must also check at transmission time. Examples of this include IPv6 or vlan packets on a NIC that only supports IPv4 offloading. Signed-off-by: Jesse Gross <jesse@nicira.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * net offloading: Convert dev_gso_segment() to use precomputed features.Jesse Gross2011-01-101-5/+3Star
| | | | | | | | | | | | | | | | | | | | This switches dev_gso_segment() to use the device features computed by the centralized routine. In doing so, it fixes a problem where it would always use dev->features, instead of those appropriate to the number of vlan tags if any are present.

| * net offloading: Pass features into netif_needs_gso().Jesse Gross2011-01-103-12/+10Star
| | | | | | | | | | | | | | | | | | | | Now that there is a single function that can compute the device features relevant to a packet, we don't want to run it for each offload. This converts netif_needs_gso() to take the features of the device, rather than computing them itself. Signed-off-by: Jesse Gross <jesse@nicira.com> Signed-off-by: David S.

| * net offloading: Generalize netif_get_vlan_features().Jesse Gross2011-01-102-10/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | netif_get_vlan_features() is currently only used by netif_needs_gso(), so it only concerns itself with GSO features. However, several other places also should take into account the contents of the packet when deciding whether to offload to hardware. This generalizes the function to return features about all of the various forms of offloading. Since offloads tend to be linked together, this avoids duplicating the logic in each location (i.e. the scatter/gather code also needs the checksum logic).

| * net offloading: Accept NETIF_F_HW_CSUM for all protocols.Jesse Gross2011-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently only have software fallback for one type of checksum: the TCP/UDP one's complement. This means that a protocol that uses hardware offloading for a different type of checksum (FCoE, SCTP) must directly check the device's features and do the right thing ahead of time. By the time we get to dev_can_checksum(), we're only deciding whether to apply the one algorithm in software or hardware. NETIF_F_HW_CSUM has the same capabilities as the software version, so we should always use it if present. The primary advantage of this is multiply tagged vlans can use hardware checksumming.
