2019-12-10iwlwifi: pcie: move power gating workaround earlier in the flowLuca Coelho2-25/+30
We need to reset the NIC after setting the bits to enable power gating and that cannot be done too late in the flow otherwise it cleans other registers and things that were already configured, causing initialization to fail. In order to fix this, move the function to the common code in trans.c so it can be called directly from there at an earlier point, just after the reset we already do during initialization. Fixes: 9a47cb988338 ("iwlwifi: pcie: add workaround for power gating in integrated 22000") Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=205719 Cc: stable@ver.kernel.org # 5.4+ Reported-by: Anders Kaseorg <andersk@mit.edu> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

This reverts commit 968dcfb4905245dc64d65312c0d17692fa087b99. Both that commit and commit 809805a820c6445f7a701ded24fdc6bbc841d1e4 attempted to fix the same bug (dead assignments to the local variable cfg), but they did so in incompatible ways. When they were both merged, independently of each other, the combination actually caused the bug to reappear, leading to a firmware crash on boot for some cards. https://bugzilla.kernel.org/show_bug.cgi?id=205719 Signed-off-by: Anders Kaseorg <andersk@mit.edu> Acked-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2019-11-28mwifiex: fix possible heap overflow in mwifiex_process_country_ie()Ganapathi Bhat1-2/+11
mwifiex_process_country_ie() function parse elements of bss descriptor in beacon packet. When processing WLAN_EID_COUNTRY element, there is no upper limit check for country_ie_len before calling memcpy. The destination buffer domain_info->triplet is an array of length MWIFIEX_MAX_TRIPLET_802_11D(83). The remote attacker can build a fake AP with the same ssid as real AP, and send malicous beacon packet with long WLAN_EID_COUNTRY elemen (country_ie_len > 83). Attacker can force STA connect to fake AP on a different channel. When the victim STA connects to fake AP, will trigger the heap buffer overflow. Fix this by checking for length and if found invalid, don not connect to the AP. This fix addresses CVE-2019-14895.

2019-11-23sfc: suppress MCDI errors from ARFSEdward Cree2-6/+30
In high connection count usage, the NIC's filter table may be filled with sufficiently many ARFS filters that further insertions fail. As this does not represent a correctness issue, do not log the resulting MCDI errors. Add a debug-level message under the (by default disabled) rx_status category instead; and take the opportunity to do a little extra expiry work. Since there are now multiple workitems able to call __efx_filter_rfs_expire on a given channel, it is possible for them to race and thus pass quotas which, combined, exceed rfs_filter_count. Thus, don't WARN_ON if we loop all the way around the table with quota left over.

2019-11-23sfc: change ARFS expiry mechanismEdward Cree4-32/+45
The old rfs_filters_added method for determining the quota could potentially allow the NIC to become filled with old filters, which never get tested for expiry. Instead, explicitly make expiry check work depend on the number of filters installed, and don't count checking slots without filters in as doing work. This guarantees that each filter will be checked for expiry at least once every thirty seconds (assuming the channel to which it belongs is NAPI polling actively) regardless of fill level.

Bruce updates the driver to store the number of functions the device has so that it won't have to compute it when setting safe mode capabilities. Adds a check to adjust the reporting of capabilities for devices with more than 4 ports, which differ for devices with less than 4 ports. Brett adds a helper function to determine if the VF is allowed to do VLAN operations based on the host's VF configuration. Also adds a new function that initializes VLAN stripping (enabled/disabled) for the VF based on the device supported capabilities. Adds a check if the vector index is valid with the respect to the number of transmit and receive queues configured when we set coalesce settings for DCB. Adds a check if the promisc_mask contains ICE_PROMISC_VLAN_RX or ICE_PROMISC_VLAN_TX so that VLAN 0 promiscuous rules to be removed. Add a helper macro for a commonly used de-reference of a pointer to &pf->dev->pdev. Jesse fixes an issue where if an invalid virtchnl request from the VF, the driver would return uninitialized data to the VF from the PF stack, so ensure the stack variable is initialized earlier. Add helpers to the virtchnl interface make the reporting of strings consistent and help reduce stack space. Implements VF statistics gathering via the kernel ndo_get_vf_stats(). Akeem ensures we disable the state flag for each VF when its resources are returned to the device. Tony does additional cleanup in the driver to ensure the when we allocate and free memory within the same function, we should not be using devm_* variants; use regular alloc and free functions. Henry implements code to query and set the number of channels on the primary VSI for a PF via ethtool. Jake cleans up needless NULL checks in ice_sched_cleanup_all(). Kevin updates the firmware API version to align with current NVM images. v2: Added "Fixes:" tag to patch 5 commit description and added the use of netif_is_rxfh_configured() in patch 13 to see if RSS has been configured by the user, if so do not overwrite that configuration. ==================== Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com>

The FW_ETH_TX_EO_WR used for sending UDP Segmentation Offload (USO) requests expects the headers to be part of the descriptor and the payload to be part of the SGL containing the DMA mapped addresses. Hence, the DMA address in the first entry of the SGL can start after the packet headers. Currently, unmap_sgl() tries to unmap from this wrong offset, instead of the originally mapped DMA address. So, use existing unmap_skb() instead, which takes originally saved DMA addresses as input. Update all necessary Tx paths to save the original DMA addresses, so that unmap_skb() can unmap them properly. v2: - No change.

2019-11-23net/mlx5: DR, Refactor VXLAN GPE flex parser tunnel code for SW steeringYevgeny Kliteynik4-57/+66
Refactor flex parser tunnel code: - Add definition for flex parser tunneling header for VXLAN-GPE - Use macros for VXLAN-GPE SW steering when building STE - Refactor the code to reflect that this is a VXLAN GPE only code and not a general flex parser code. This also significantly simplifies addition of more flex parser protocols, such as Geneve.

2019-11-23net/mlx5: Don't write read-only fields in MODIFY_HCA_VPORT_CONTEXT commandLeon Romanovsky1-20/+7
The MODIFY_HCA_VPORT_CONTEXT uses field_selector to mask fields needed to be written, other fields are required to be zero according to the HW specification. The supported fields are controlled by bitfield and limited to vport state, node and port GUIDs.

2019-11-23ice: implement VF stats NDOJesse Brandeburg3-0/+57
Implement the VF stats gathering via the kernel via ndo_get_vf_stats(). The driver will show per-VF stats in the output of the ip -s link show dev <PF> command.

2019-11-23ice: add helpers for virtchnlJesse Brandeburg1-71/+63
The virtchannel interface was repeating a lot of strings and wasting storage space in the kernel. There was also inconsistent messages for the same thing. Consolidate all those messages and bit checks into a couple of helper functions. Also, reduce stack space usage by simplifying getting the pointer to the pf using a helper.

2019-11-23ice: Add ice_pf_to_dev(pf) macroBrett Creeley10-341/+389
We use &pf->dev->pdev all over the code. Add a simple macro to do this for us. When multiple de-references like this are being done add a local struct device variable.

2019-11-23ice: Do not use devm* functions for local usesTony Nguyen5-88/+80
In situations where we alloc and free memory within the same function do not use the devm_* variants; use regular alloc and free functions. Remove any unused vars if there are no usages after these changes. Also, replace an allocate and copy with kmemdup() and remove an unnecessary memset() to 0 after a kzalloc().

2019-11-23ice: Refactor removal of VLAN promiscuous rulesBrett Creeley1-4/+9
Currently ice_clear_vsi_promisc() detects if the VLAN ID sent is not 0 and sets the recipe_id to ICE_SW_LKUP_PROMISC_VLAN in that case and ICE_SW_LKUP_PROMISC if the VLAN_ID is 0. However this doesn't allow VLAN 0 promiscuous rules to be removed, but they can be added. Fix this by checking if the promisc_mask contains ICE_PROMISC_VLAN_RX or ICE_PROMISC_VLAN_TX. This change was made to match what is being done for ice_set_vsi_promisc().
