Maximum trunc length is defined by MAX_AH_AUTH_LEN (in bytes) and need to be checked when this value is set (in bits) by the user. In ah4.c and ah6.c a BUG_ON() checks this condiftion. Signed-off-by:

Currently the skb array is not fully allocated, and the allocation is done as it's requested, which is not the expected way. This patch just allocate the full skb array at driver initialization. Also, this patch increases ehea version to 107. Signed-off-by:

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). Reported-by:

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:

HTB takes into account skb is segmented in stats updates. Generalize this to all schedulers. They should use qdisc_bstats_update() helper instead of manipulating bstats.bytes and bstats.packets Add bstats_update() helper too for classes that use gnet_stats_basic_packed fields. Note : Right now, TCQ_F_CAN_BYPASS shortcurt can be taken only if no stab is setup on qdisc. Signed-off-by:

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. Signed-off-by:

Driver is reading flash fw version from defined address, this address may be invalid. Indeed Driver should read address for fw version through flash layout table. Flash layout table has defined region and address for fw version address should be read from fw image region. Driver has check for old firmware, this bug can cause driver load fail. This patch will try to read fw version from flash image region, if that fails, read from defined address. Signed-off-by:

Dan Rosenberg pointed out that there were some signed comparison bugs in the phonet protocol. http://marc.info/?l=full-disclosure&m=129424528425330&w=2 The problem is that we check for array overflows but "protocol" is signed and we don't check for array underflows. If you have already have CAP_SYS_ADMIN then you could use the bugs to get root, or someone could cause an oops by mistake. Signed-off-by:

Alexander Duyck authored
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. Signed-off-by:

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.

When disable the Rx logic globally, we would also want to disable the per Rx queue receive logic by per queue Rx control register RXDCTL so no more DMA is happening from the packet buffer to the receive buffer associated with the Rx ring, before we start unmapping Rx ring receive buffer. The hardware may take max of 100us before the corresponding Rx queue is really disabled. Added ixgbe_disable_rx_queue() for this purpose. Signed-off-by:

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. Reported-by:

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). Signed-off-by:

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 authored
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 authored
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. Signed-off-by:
-
Jesse Gross authored
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 authored
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). Suggested-by:
