* sfc: Use netif_device_{detach,attach}() around reset and self-testBen Hutchings2011-05-16
| | | | | | | | | | | | | | We need to keep the TX queues stopped throughout a reset, without triggering the TX watchdog and regardless of the link state. The proper way to do this is to use netif_device_{detach,attach}() just as we do around suspend/resume, rather than the current bodge of faking link-down. Since we also need to do this during an offline self-test and we perform a reset during that, add these function calls outside of efx_reset_down() and efx_reset_up().

* ipv4: Kill spurious write to iph->daddr in ip_forward_options().David S. Miller2011-05-13
| | | | | | | | | | | | | | | | | | | | | | | | 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: David S. Miller <davem@davemloft.net>

* net:set valid name before calling ndo_init()Peter Pan(潘卫平)2011-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 1c5cae815d19 (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.

* net: ipv4: add IPPROTO_ICMP socket kindVasiliy Kulikov2011-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| * tg3: Allow ethtool to enable/disable loopback.Mahesh Bandewar2011-05-12
| | | | | | | | | | | | | | | | | | This patch adds tg3_set_features() to handle loopback mode. Currently the capability is added for the devices which support internal MAC loopback mode. So when enabled, it enables internal-MAC loopback. Signed-off-by: Mahesh Bandewar <maheshb@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | use tty_insert_flip_string and tty_flip_buffer_push to deliver incoming data packets from the IrDA device instead of delivering the packets directly to the line discipline. Following later approach resulted in warning "Sleeping function called from invalid context".

| * net: group FCoE related feature flagsYi Zou2011-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Michał Mirosław's patch (http://patchwork.ozlabs.org/patch/94421/) fixes the issue (http://patchwork.ozlabs.org/patch/94188/) about not populating FCoE related flags correctly on vlan devices. However, only NETIF_F_FCOE_CRC is part of the NETIF_F_ALL_TX_OFFLOADS right now, where weed NETIF_F_FCOE_MTU and NETIF_F_FSO as well. Therefore, add NETIF_F_ALL_FCOE to indicate feature flags used by FCoE TX offloads. These include NETIF_F_FCOE_CRC, NETIF_F_FCOE_MTU, and NETIF_F_FSO and add them to be part of NETIF_F_ALL_TX_OFFLOADS. This would eventually make sure all FCoE needed flags are populated properly to vlan devices. Signed-off-by: Yi Zou <yi.zou@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * net: Fix vlan_features propagationMichał Mirosław2011-05-12
| | | | | | | | | | | | | | | | | | | | | | | | Fix VLAN features propagation for devices which change vlan_features. For this to work, driver needs to make sure netdev_features_changed() gets called after the change (it is e.g. after ndo_set_features()). Side effect is that a user might request features that will never be enabled on a VLAN device. Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: David S.

| * garp: remove last synchronize_rcu() callEric Dumazet2011-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When removing last vlan from a device, garp_uninit_applicant() calls synchronize_rcu() to make sure no user can still manipulate struct garp_applicant before we free it. Use call_rcu() instead, as a step to further net_device dismantle optimizations. Add the temporary garp_cleanup_module() function to make sure no pending call_rcu() are left at module unload time [ this will be removed when kfree_rcu() is available ] Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Resending this patch with few changes. Avoid multiple queues when MSI or MSI-X not available Limit number of Tx queues to 1 if MSI/MSI-X support is not configured in the kernel. This will make number of tx and rx queues equal when MSI/X is not configured thus providing better performance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While trying to remove useless synchronize_rcu() calls, I found l2tp is indeed incorrectly using two of such calls, but also bumps tunnel refcount after list insertion. tunnel refcount must be incremented before being made publically visible by rcu readers. This fix can be applied to 2.6.35+ and might need a backport for older kernels, since things were shuffled in commit fd558d186df2c (l2tp: Split pppol2tp patch into separate l2tp and ppp parts) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Paul E.
