All drivers that support modification of the RX flow hash indirection table initialise it in the same way: RX rings are assigned to table entries in rotation. Make that default policy explicit by having them call a ethtool_rxfh_indir_default() function. In the ethtool core, add support for a zero size value for ETHTOOL_SRXFHINDIR, which resets the table to this default.

Add a new ethtool operation (get_rxfh_indir_size) to get the indirectional table size. Use this to validate the user buffer size before calling get_rxfh_indir or set_rxfh_indir. Use get_rxnfc to get the number of RX rings, and validate the contents of the new indirection table before calling set_rxfh_indir. Remove this validation from drivers.

In order to find out the device's RX flow hash table size, ethtool initially uses ETHTOOL_GRXFHINDIR with a buffer size of zero. This must be supported, but it is not necessary to support any other user buffer size less than the device table size. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

When establishing a unix connection on stream sockets the server end receives an skb with socket in its receive queue. Report who is waiting for these ends to be accepted for listening sockets via NLA. There's a lokcing issue with this -- the unix sk state lock is required to access the peer, and it is taken under the listening sk's queue lock. Strictly speaking the queue lock should be taken inside the state lock, but since in this case these two sockets are different it shouldn't lead to deadlock.

Actually, the socket path if it's not anonymous doesn't give a clue to which file the socket is bound to. Even if the path is absolute, it can be unlinked and then new socket can be bound to it. With this NLA it's possible to check which file a particular socket is really bound to. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The socket inode is used as a key for lookup. This is effectively the only really unique ID of a unix socket, but using this for search currently has one problem -- it is O(number of sockets) :( Does it worth fixing this lookup or inventing some other ID for unix sockets?

I've made a mistake when fixing the sock_/inet_diag aliases :( 1. The sock_diag layer should request the family-based alias, not just the IPPROTO_IP one; 2. The inet_diag layer should request for AF_INET+protocol alias, not just the protocol one. Thus fix this. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S.

After commit 8e2ec639 ("ipv6: don't use inetpeer to store metrics for routes.") the test in rt6_alloc_cow() for setting the ANYCAST flag is now wrong. 'rt' will always now have a plen of 128, because it is set explicitly to 128 by ip6_rt_copy. So to restore the semantics of the test, check the destination prefix length of 'ort'.

Don't just succeed with a route that has a NULL neighbour attached. This follows the behavior of addrconf_dst_alloc(). Allowing this kind of route to end up with a NULL neigh attached will result in packet drops on output until the route is somehow invalidated, since nothing will meanwhile try to lookup the neigh again. A statistic is bumped for the case where we see a neigh-less route on output, but the resulting packet drop is otherwise silent in nature, and frankly it's a hard error for this to happen and ipv6 should do what ipv4 does which is say something in the kernel logs.

1. Added module parameters sr_iov and probe_vf for controlling enablement of SRIOV mode. 2. Increased default max num-qps, num-mpts and log_num_macs to accomodate SRIOV mode 3. Added port_type_array as a module parameter to allow driver startup with ports configured as desired. In SRIOV mode, only ETH is supported, and this array is ignored; otherwise, for the case where the FW supports both port types (ETH and IB), the port_type_array parameter is used. By default, the port_type_array is set to configure both ports as IB. 4. When running in sriov mode, the master needs to initialize the ICM eq table to hold the eq's for itself and also for all the slaves. 5. mlx4_set_port_mask() now invoked from mlx4_init_hca, instead of in mlx4_dev_cap. 6. Introduced sriov VF (slave) device startup/teardown logic (mainly procedures mlx4_init_slave, mlx4_slave_exit, mlx4_slave_cap, mlx4_slave_exit and flow modifications in __mlx4_init_one, mlx4_init_hca, and mlx4_setup_hca). VFs obtain their startup information from the PF (master) device via the comm channel. 7. In SRIOV mode (both PF and VF), MSI_X must be enabled, or the driver aborts loading the device. 8. Do not allow setting port type via sysfs when running in SRIOV mode. 9. mlx4_get_ownership: Currently, only one PF is supported by the driver. If the HCA is burned with FW which enables more than one PF, only one of the PFs is allowed to run. The first one up grabs a FW ownership semaphone -- all other PFs will find that semaphore taken, and the driver will not allow them to run.

When running in SRIOV mode, driver should not automatically start/stop the mlx4_core upon sensing an HCA internal error -- doing this disables/enables sriov, which will cause the hypervisor to hang if there are running VMs with attached VFs. In addition, on VMs the catas process should not run at all, since the HCA error buffer is not available to VMs in the BARs.

In the previous implementation mtts are managed by: 1. order - log(mtt segments), 'mtt segment' groups several mtts together. 2. first_seg - segment location relative to mtt table. In the current implementation: 1. order - log(mtts) rather than segments 2. offset - mtt index in mtt table Note: The actual mtt allocation is made in segments but it is transparent to callers. Rational: The mtt resource holders are not interested on how the allocation of mtt is done, but rather on how they will use it.
