The update to ibmvnic_init to allow an EAGAIN return code broke the calling of ibmvnic_init from ibmvnic_probe. The code now will return from this point in the probe routine if anything other than EAGAIN is returned. The check should be to see if rc is non-zero and not equal to EAGAIN. Without this fix, the vNIC driver can return 0 (success) from its probe routine due to ibmvnic_init returning zero, but before completing the probe process and registering with the netdev layer.

Thomas Falcon says: ==================== ibmvnic: Correct long-term-mapped buffer error handling This patch set fixes the error-handling of long-term-mapped buffers during adapter initialization and reset. The first patch fixes a bug in an incorrectly defined descriptor that was keeping the return codes from the VIO server from being properly checked. The second patch fixes and cleans up the error-handling implementation. ==================== Signed-off-by:

Thomas Falcon authored
The patch stores the return code of the REQUEST_MAP_RSP sub-CRQ command in the private data structure, where it can be later checked during device open or a reset. In the case of a reset, the mapping request to the vNIC Server may fail, especially in the case of a partition migration. The driver attempts to handle this by re-allocating the buffer and re-sending the mapping request. The original error handling implementation was removed. The separate function handling the REQUEST_MAP response message was also removed, since it is now simple enough to be handled in the ibmvnic_handle_crq function. Signed-off-by:

Currently in both ipv4 and ipv6 code path, the ack packet received when sk at TCP_NEW_SYN_RECV state is not filtered by socket filter or cgroup filter since it is handled from tcp_child_process and never reaches the tcp_filter inside tcp_v4_rcv or tcp_v6_rcv. Adding a tcp_filter hooks here can make sure all the ingress tcp packet can be correctly filtered. Signed-off-by:

for connected socket, the incoming_cpu field in the sock struct is not going to change frequently, but we are setting it unconditionally for each packet. Since sk_incoming_cpu and sk_flags share the same cacheline, and the latter is access by udp_recvmsg(), this cause a cache miss for each packet for UDP connected socket. With this patch, we set the incoming cpu field only when the ingress cpu really changes. This gives a small but measurable performance improvement for connected UDP socket. Signed-off-by:

This adds the new getsockopt(2) option SO_PEERGROUPS on SOL_SOCKET to retrieve the auxiliary groups of the remote peer. It is designed to naturally extend SO_PEERCRED. That is, the underlying data is from the same credentials. Regarding its syntax, it is based on SO_PEERSEC. That is, if the provided buffer is too small, ERANGE is returned and @optlen is updated. Otherwise, the information is copied, @optlen is set to the actual size, and 0 is returned. While SO_PEERCRED (and thus `struct ucred') already returns the primary group, it lacks the auxiliary group vector. However, nearly all access controls (including kernel side VFS and SYSVIPC, but also user-space polkit, DBus, ...) consider the entire set of groups, rather than just the primary group. But this is currently not possible with pure SO_PEERCRED. Instead, user-space has to work around this and query the system database for the auxiliary groups of a UID retrieved via SO_PEERCRED. Unfortunately, there is no race-free way to query the auxiliary groups of the PID/UID retrieved via SO_PEERCRED. Hence, the current user-space solution is to use getgrouplist(3p), which itself falls back to NSS and whatever is configured in nsswitch.conf(3). This effectively checks which groups we *would* assign to the user if it logged in *now*. On normal systems it is as easy as reading /etc/group, but with NSS it can resort to quering network databases (eg., LDAP), using IPC or network communication. Long story short: Whenever we want to use auxiliary groups for access checks on IPC, we need further IPC to talk to the user/group databases, rather than just relying on SO_PEERCRED and the incoming socket. This is unfortunate, and might even result in dead-locks if the database query uses the same IPC as the original request. So far, those recursions / dead-locks have been avoided by using primitive IPC for all crucial NSS modules. However, we want to avoid re-inventing the wheel for each NSS module that might be involved in user/group queries. Hence, we would preferably make DBus (and other IPC that supports access-management based on groups) work without resorting to the user/group database. This new SO_PEERGROUPS ioctl would allow us to make dbus-daemon work without ever calling into NSS.

On UDP packets processing, if the BH is the bottle-neck, it always sees a cache miss while updating rmem_alloc; try to avoid it prefetching the value as soon as we have the socket available. Performances under flood with multiple NIC rx queues used are unaffected, but when a single NIC rx queue is in use, this gives ~10% performance improvement. Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-06-20 This series contains updates to i40e and i40evf only. Björn adds additional XDP support for i40e, by adding pass and drop actions and XDP_TX action support. Jake fixes a possible NULL pointer dereference in i40evf_get_ethtool_stats() which could occur if the VF fails to recover from a reset, and then a user requests statistics. Changed the use of dev_info() to dev_dbg() for vf_capability client routine so that the standard log is not spammed with this information which "might" cause administrators to worry. Also added more code comments to help explain why udp_port has be in host byte order and to avoid future changes which may cause this to break. Fixed the holding of the RTNL lock for the entire reset routine, reduced the scope so that the reset function will handle its own lock, so that we do not have to wrap every reference to i40e_do_reset() with RTNL lock/unlock. Alice updates flags related to firmware interactions for WoL and admin queue command address with the correct value. Sudheer makes a fix to ensure that the array is not accessed past the size of the array. Greg fixes the parsing of firmware 4.33 admin queue commmand "Get CEE DCBX PER CFG" because the firmware now creates the oper_prio_tc nibbles reversed from those in the CDD Priority Group sub-TLV. Carolyn adds a check and message to let users know that when in MFP mode, changing RSS hash input set is not supported. Shannon makes the partition bandwidth control more generic since it is not in just one form of multi-function partitioning (MFP). Also fixes a bug which was causing the firmware confusion in some reset sequences, when we were disabling interrupts and we were clearing the whole register. Instead we should only be clearing the CAUSE_ENA bit when disabling interrupts. Filip adds support for OEM firmware version, so that if a OEM specific adapter is detected, ethtool reports the OEM product version in the firmware version string instead of etrack id. Alan fixes a bug where the driver was not correctly exiting overflow promiscuous mode, which can happen if "too many" MAC filters are added, putting the driver into overflow promiscuous mode, and the filters are then removed. The bug occurs because the conditional for toggling promiscuous mode was only be executed when enabled and not when it was disabled. ==================== Signed-off-by:

Julien Gomes says: ==================== ipmr/ip6mr: add Netlink notifications on cache reports Currently, all ipmr/ip6mr cache reports are sent through the mroute/mroute6 socket only.

We recently refactored i40e_do_reset() and its friends to be able to hold the RTNL lock only for the portions that actually need to be protected. However, a separate refactoring added several new callers of these functions during the PCIe error recovery and suspend/resume cycles. When merging the changes together, it was not noticed that we could reduce the RTNL scope by letting the reset function handle the lock itself, as previously it was not possible. Fix this by replacing these call sites to indicate that the reset function should handle its own lock. This enables multiple PFs to reset or resume simultaneously without serializing the resets via the RTNL lock. The end result is that on systems with lots of PFs and VFs the resets don't stall waiting for each other to finish. It is probable that we can also do the same for i40e_do_reset_safe, but this author did not research that change carefully enough to be confident. Signed-off-by:

There exists a bug in which the driver does not correctly exit overflow promiscuous mode. This can occur if "too many" mac filters are added, putting the driver into overflow promiscuous mode, and the filters are then removed. When the failed filters are removed, the driver reports exiting overflow promiscuous mode which is correct, however traffic continues to be received as if in promiscuous mode still. The bug occurs because the conditional for toggling promiscuous mode was set to only execute when promiscuous mode was enabled and not when it was disabled as well. This patch fixes the conditional to correctly execute when promiscuous mode is toggled and not just enabled. Without this patch, the driver is unable to correctly exit overflow promiscuous mode.
