2019-02-25net: dsa: mv88e6xxx: Default CMODE to 1000BaseX only on 6390XMarek Behún1-0/+2
Commit 787799a9d555 sets the SERDES interfaces of 6390 and 6390X to 1000BaseX, but this is only needed on 6390X, since there are SERDES interfaces which can be used on lower ports on 6390. This commit fixes this by returning to previous behaviour on 6390. (Previous behaviour means that CMODE is not set at all if requested mode is NA). This is needed on Turris MOX, where the 88e6190 is connected to CPU in 2500BaseX mode.

2019-02-25ice: clear VF ARQLEN register on resetMitch Williams2-0/+6
On older devices like X710 and X722, the VF's ARQLEN register is cleared on reset, so the VF driver uses that register to detect an unannounced reset. Unfortunately, on devices controlled by ice, this register is NOT cleared on reset. This causes the VF to miss resets, and even on properly-announced resets, the VF driver complains that it didn't see the reset. To fix this, we'll do it in software. When we handle a VF reset (whether triggered by software or VFLR), clear this register after the HW reset is complete.

2019-02-25ice: don't spam VFs with link messagesMitch Williams1-1/+2
Don't send a link message to the VFs unless link actually changes state. This avoids a small timing hole in some VF drivers that can cause an apparent TX hang if they receive a link status message at the wrong time. Although we have fixed the timing hole in the current VF driver, there are still lots of drivers in the field that have this timing hole. Let's not fall into it if we can avoid it.

2019-02-25ice: fix issue where host reboots on unload when iommu=onBrett Creeley1-17/+54
Currently if the kernel has the intel_iommu=on parameter set, on some platforms removing the driver causes a system reboot. In initialization we associate the control queue interrupts with the pf->hw_oicr_idx and enable the interrupts by setting the CAUSE_ENA bit. The problem comes on teardown because we are not clearing the CAUSE_ENA bit for the control queues, but the vector at pf->hw_oicr_idx (miscellaneous interrupt vector) gets disabled. Fix this by clearing the CAUSE_ENA bit in the appropriate control queue registers on when freeing the miscellaneous interrupt vector. Also, move the call to ice_free_irq_msix_misc() to after ice_deinit_sw() in ice_remove() because ice_deinit_sw() makes an AQ call, but ice_free_irq_msix_misc() disables the miscellaneous vector and it's associated interrupts. Also, create two small helper functions to enable and disable the control queue interrupts respectively.

2019-02-25ice: fix ice_remove_rule_internal vsi_list handlingJacob Keller1-2/+13
When adding multiple VLANs to the same VSI, the ice_add_vlan code will share the VSI list, so as not to create multiple unnecessary VSI lists. Consider the following flow ice_add_vlan(hw, <VSI 0 VID 7, VSI 0 VID 8, VSI 0 VID 9>) Where we add three VLAN filters for VIDs 7, 8, and 9, all for VSI 0. The ice_add_vlan will create a single vsi_list and share it among all the filters. Later, if we try to remove a VLAN, ice_remove_vlan(hw, <VSI 0 VID 7>) Then the removal code will update the vsi_list and remove VSI 0 from it. But, since the vsi_list is shared, this breaks the list for the other users who reference it. We actually even free the VSI list memory, and may result in segmentation faults. This is due to the way that VLAN rule share VSI lists with reference counts, and is caused because we call ice_rem_update_vsi_list even when the ref_cnt is greater than one. To fix this, handle the case where ref_cnt is greater than one separately. In this case, we need to remove the associated rule without modifying the vsi_list, since it is currently being referenced by another rule. Instead, we just need to decrement the VSI list ref_cnt. The case for handling sharing of VSI lists with multiple VSIs is not currently supported by this code. No such rules will be created today, and this code will require changes if/when such code is added.

The patch enables returning 'type' in msghdr for records that are retrieved with MSG_PEEK in recvmsg. Further it prevents records peeked from socket from getting clubbed with any other record of different type when records are subsequently dequeued from strparser. For each record, we now retain its type in sk_buff's control buffer cb[]. Inside control buffer, record's full length and offset are already stored by strparser in 'struct strp_msg'. We store record type after 'struct strp_msg' inside 'struct tls_msg'. For tls1.2, the type is stored just after record dequeue. For tls1.3, the type is stored after record has been decrypted. Inside process_rx_list(), before processing a non-data record, we check that we must be able to return back the record type to the user application. If not, the decrypted records in tls context's rx_list is left there without consuming any data.
