This patch cleans up two minor issues in ixgbe_down. Specifically it addresses the fact that the VFs should not be pinged until after interrupts are disabled otherwise they might still get a response. It also drops the use of the txdctl temporary variable since the only bit we should be writing to the TXDCTL registers during a shutdown is the flush bit. Signed-off-by:

This change merges the ATR table reinitialization into the service task. This is yet another opportunity to avoid any race conditions as we don't want to be attempting to reinitialize the table during a possible reset. In addition this change adds a counter for table reinitialization so that it can be tracked as part of the regular statistics. Signed-off-by:

This change is meant to further help to reduce possible configuration collisions between the various tasklets. This change combines the device reset with the service task. As a result it is now not possible to be updating the link on the device while also resetting the part. Signed-off-by:

This patch is meant to merge the functionality of the ixgbe watchdog task into the service task. By doing this all link state functionality will be controlled by a single task. As a result the reliability of the interface will be improved as the likelihood of any race conditions is further reduced. Signed-off-by:

This change is meant to address several race conditions with multi-speed fiber SFP+ modules in 82599 adapters. Specifically issues have been seen in which both the SFP configuration and the multi-speed fiber configuration are running simultaneously which will result in the device getting into an erroneous link down state.

This change moves flags and state into the same cacheline. The reason for this change is because both are frequently read around the same time and infrequently written. By combining them into the same cacheline this should help to reduce memory utilization. Signed-off-by:

The semaphore can be in locked state upon driver load, particularly on 82598 if a machine is rebooted due to panic and the semaphore was acquired just prior to the panic. This patch unlocks the semaphore if it times out. Signed-off-by:

This code block executes when opt->srr_is_hit is set. It will be set only by ip_options_rcv_srr(). ip_options_rcv_srr() walks until it hits a matching nexthop in the SRR option addresses, and when it matches one 1) looks up the route for that nexthop and 2) on route lookup success it writes that nexthop value into iph->daddr. ip_forward_options() runs later, and again walks the SRR option addresses looking for the option matching the destination of the route stored in skb_rtable(). This route will be the same exact one looked up for the nexthop by ip_options_rcv_srr(). Therefore "rt->rt_dst == iph->daddr" must be true. All it really needs to do is record the route's source address in the matching SRR option adddress. It need not write iph->daddr again, since that has already been done by ip_options_rcv_srr() as detailed above. Signed-off-by: -

In commit 1c5cae81 (net: call dev_alloc_name from register_netdevice), a bug of bonding was involved, see example 1 and 2. In register_netdevice(), the name of net_device is not valid until dev_get_valid_name() is called. But dev->netdev_ops->ndo_init(that is bond_init) is called before dev_get_valid_name(), and it uses the invalid name of net_device. I think register_netdevice() should make sure that the name of net_device is valid before calling ndo_init(). example 1: modprobe bonding ls /proc/net/bonding/bond%d ps -eLf root 3398 2 3398 0 1 21:34 ? 00:00:00 [bond%d] example 2: modprobe bonding max_bonds=3 [ 170.100292] bonding: Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) [ 170.101090] bonding: Warning: either miimon or arp_interval and arp_ip_target module parameters must be specified, otherwise bonding will not detect link failures! see bonding.txt for details.

The file st5481_init.c locally defines and initializes the adapter_list variable, but does not use it for anything. Removing the list makes it possible to remove the list field from the st5481_adapter data structure. In the function probe_st5481, it also makes it possible to free the locally allocated adapter value on an error exit. Signed-off-by:

This patch adds IPPROTO_ICMP socket kind. It makes it possible to send ICMP_ECHO messages and receive the corresponding ICMP_ECHOREPLY messages without any special privileges. In other words, the patch makes it possible to implement setuid-less and CAP_NET_RAW-less /bin/ping. In order not to increase the kernel's attack surface, the new functionality is disabled by default, but is enabled at bootup by supporting Linux distributions, optionally with restriction to a group or a group range (see below). Similar functionality is implemented in Mac OS X: http://www.manpagez.com/man/4/icmp/ A new ping socket is created with socket(PF_INET, SOCK_DGRAM, PROT_ICMP) Message identifiers (octets 4-5 of ICMP header) are interpreted as local ports. Addresses are stored in struct sockaddr_in. No port numbers are reserved for privileged processes, port 0 is reserved for API ("let the kernel pick a free number"). There is no notion of remote ports, remote port numbers provided by the user (e.g. in connect()) are ignored. Data sent and received include ICMP headers. This is deliberate to: 1) Avoid the need to transport headers values like sequence numbers by other means. 2) Make it easier to port existing programs using raw sockets. ICMP headers given to send() are checked and sanitized. The type must be ICMP_ECHO and the code must be zero (future extensions might relax this, see below). The id is set to the number (local port) of the socket, the checksum is always recomputed. ICMP reply packets received from the network are demultiplexed according to their id's, and are returned by recv() without any modifications. IP header information and ICMP errors of those packets may be obtained via ancillary data (IP_RECVTTL, IP_RETOPTS, and IP_RECVERR). ICMP source quenches and redirects are reported as fake errors via the error queue (IP_RECVERR); the next hop address for redirects is saved to ee_info (in network order). socket(2) is restricted to the group range specified in "/proc/sys/net/ipv4/ping_group_range". It is "1 0" by default, meaning that nobody (not even root) may create ping sockets. Setting it to "100 100" would grant permissions to the single group (to either make /sbin/ping g+s and owned by this group or to grant permissions to the "netadmins" group), "0 4294967295" would enable it for the world, "100 4294967295" would enable it for the users, but not daemons. The existing code might be (in the unlikely case anyone needs it) extended rather easily to handle other similar pairs of ICMP messages (Timestamp/Reply, Information Request/Reply, Address Mask Request/Reply etc.). Userspace ping util & patch for it: http://openwall.info/wiki/people/segoon/ping For Openwall GNU/*/Linux it was the last step on the road to the setuid-less distro. A revision of this patch (for RHEL5/OpenVZ kernels) is in use in Owl-current, such as in the 2011/03/12 LiveCD ISOs: http://mirrors.kernel.org/openwall/Owl/current/iso/ Initially this functionality was written by Pavel Kankovsky for Linux 2.4.32, but unfortunately it was never made public. All ping options (-b, -p, -Q, -R, -s, -t, -T, -M, -I), are tested with the patch. PATCH v3: - switched to flowi4. - minor changes to be consistent with raw sockets code. PATCH v2: - changed ping_debug() to pr_debug(). - removed CONFIG_IP_PING. - removed ping_seq_fops.owner field (unused for procfs). - switched to proc_net_fops_create(). - switched to %pK in seq_printf(). PATCH v1: - fixed checksumming bug. - CAP_NET_RAW may not create icmp sockets anymore. RFC v2: - minor cleanups. - introduced sysctl'able group range to restrict socket(2). Signed-off-by:

Added code to take FW dump via ethtool. Dump level can be controlled via setting the dump flag. A get function is provided to query the current setting of the dump flag. Dump data is obtained from the driver via a separate get function. Changes from v3: Fixed buffer length issue in ethtool_get_dump_data function. Updated kernel doc for ethtool_dump struct and get_dump_flag function. Changes from v2: Provided separate commands for get flag and data. Check for minimum of the two buffer length obtained via ethtool and driver and use that for dump buffer Pass up the driver return error codes up to the caller. Added kernel doc comments.
