If we fail to locate GPIO for any reason other than deferral or not-found-GPIO, we try to print device tree node info, however if might be freed already as we called of_node_put() on it. Acked-by:

Instead of fwnode_get_named_gpiod() that I plan to hide away, let's use the new fwnode_gpiod_get_index() that mimics gpiod_get_index(), but works with arbitrary firmware node. Reviewed-by:

There is no build time dependency on CONFIG_OF, but we do need to make sure we gate the initialization of the gpio_chip::of_node member with a proper check on CONFIG_OF_GPIO. This enables the driver to build on platforms that do not have CONFIG_OF enabled. Signed-off-by:

Jason A. Donenfeld says: ==================== WireGuard bug fixes and cleanups I've been working through some personal notes and also the whole git repo history of the out-of-tree module, looking for places where tradeoffs were made (and subsequently forgotten about) for old kernels. The first two patches in this series clean up those. The first one does so in the self-tests and self-test harness, where we're now able to expand test coverage by a bit, and we're now cooking away tests on every commit to both the wireguard-linux repo and to net-next. The second one removes a workaround for a skbuff.h bug that was fixed long ago. Finally, the last patch in the series fixes in a bug unearthed by newer Qualcomm chipsets running the rmnet_perf driver, which does UDP GRO. ==================== Signed-off-by: -

Certain drivers will pass gro skbs to udp, at which point the udp driver simply iterates through them and passes them off to encap_rcv, which is where we pick up. At the moment, we're not attempting to coalesce these into bundles, but we also don't want to wind up having cascaded lists of skbs treated separately. The right behavior here, then, is to just mark each incoming one as not on a list. This can be seen in practice, for example, with Qualcomm's rmnet_perf driver. Signed-off-by:

Before 8b700862 ("net: Don't copy pfmemalloc flag in __copy_skb_ header()"), the pfmemalloc flag used to be between headers_start and headers_end, which is a region we clear when preparing the packet for encryption/decryption. This is a parameter we certainly want to preserve, which is why 8b700862 moved it out of there. The code here was written in a world before 8b700862, though, where we had to manually account for it. This commit brings things up to speed. Signed-off-by:

Quite a bit of the test suite was designed to work with ancient kernels. Thankfully we no longer have to deal with this. This commit updates things that we can finally update and removes things that we can finally remove, to avoid the build-up of the last several years as a result of having to support ancient kernels. We can finally rely on suppress_ prefixlength being available. On the build side of things, the no-PIE hack is no longer required, and we can bump some of the tools, repair our m68k and i686-kvm support, and get better coverage of the static branches used in the crypto lib and in udp_tunnel.

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2020-01-03 This series contains updates to the ice driver only. Brett adds support for UDP segmentation offload (USO) based on the work Alex Duyck did for other Intel drivers. Refactored how the VF sets spoof checking to resolve a couple of issues found in ice_set_vf_spoofchk(). Adds the ability to track of the dflt_vsI (default VSI), since we cannot have more than one default VSI. Add a macro for commonly used "for loop" used repeatedly in the code. Cleaned up and made the VF link flows all similar. Refactor the flows of adding and deleting MAC addresses in order to simplify the logic for error conditions and setting/clearing the VF's default MAC address field. Michal moves the setting of the default ITR value from ice_cfg_itr() to the function we allocate queue vectors. Adds support for saving and restoring the ITR value for each queue. Adds a check for all invalid or unused parameters to log the information and return an error. Vignesh cleans up the driver where we were trying to write to read-only registers for the receive flex descriptors. Tony changes a netdev_info() to netdev_dbg() when the MTU value is changed. Bruce suppresses a coverity reported error that was not really an error by adding a code comment. Mitch adds a check for a NULL receive descriptor to resolve a coverity reported issue. Krzysztof prevents a potential general protection fault by adding a boundary check to see if the queue id is greater than the size of a UMEM array. Adds additional code comments to assist coverity in its scans to prevent false positives. Jake adds support for E822 devices to the driver. ==================== Signed-off-by:

Coverity reports some of the calls to xdp_rxq_info_reg() as potential issues, because the driver does not check its return value. However, those calls are wrapped with "if (!xdp_rxq_info_is_reg(&ring->xdp_rxq))" and this check alone is enough to be sure that the function will never fail. All possible states of xdp_rxq_info are: - NEW, - REGISTERED, - UNREGISTERED, - UNUSED. The driver won't mark a queue as UNUSED under no circumstance, so the return value can be ignored safely. Add comments for Coverity right above calls to xdp_rxq_info_reg() to suppress the warnings. Signed-off-by:

In ice_xsk_umem(), variable qid which is later used as an array index, is not validated for a possible boundary exceedance. Because of that, a calling function might receive an invalid address, which causes general protection fault when dereferenced. To address this, add a boundary check to see if qid is greater than the size of a UMEM array. Also, don't let user change vsi->num_xsk_umems just by trying to setup a second UMEM if its value is already set up (i.e. UMEM region has already been allocated for this VSI). While at it, make sure that ring->zca.free pointer is always zeroed out if there is no UMEM on a specified ring. Signed-off-by:

In the case where the hardware gives us a null Rx descriptor, it is theoretically possible that we could call one of our skb-construction functions with no data pointer, which would cause a panic. In real life, this will never happen - we only get null RX descriptors as the final descriptor in a chain of otherwise-valid descriptors. When this happens, the skb will be extant and we'll just call ice_add_rx_frag(), which can deal with empty data buffers. Unfortunately, Coverity does not have intimate knowledge of our hardware, so we must add a check here. Signed-off-by:

Currently when there are SR-IOV VF(s) and the user does "ip link show <pf interface>" the VF unicast MAC addresses all show 00:00:00:00:00:00 if the unicast MAC was set via VIRTCHNL (i.e. not administratively set by the host PF). This is misleading to the host administrator. Fix this by setting the VF's dflt_lan_addr.addr when the VF's unicast MAC address is configured via VIRTCHNL. There are a couple cases where we don't allow the dflt_lan_addr.addr field to be written. First, If the VF's pf_set_mac field is true and the VF is not trusted, then we don't allow the dflt_lan_addr.addr to be modified. Second, if the dflt_lan_addr.addr has already been set (i.e. via VIRTCHNL). Also a small refactor was done to separate the flow for add and delete MAC addresses in order to simplify the logic for error conditions and set/clear the VF's dflt_lan_addr.addr field.

Currently the flow for ice_set_vf_link_state() is not configuring link the same as all other VF link configuration flows. Fix this by only setting the necessary VF members in ice_set_vf_link_state() and then call ice_vc_notify_link_state() to actually configure link for the VF. This made ice_set_pfe_link_forced() unnecessary, so it was deleted. Also, this commonizes the link flows for the VF to all call ice_vc_notify_link_state(). Signed-off-by:

After each rebuild driver deallocates q_vectors, so the interrupt throttle rate (ITR) settings get lost. Create a function to save and restore ITR for each queue. If a user increases the number of queues, restore all the previous queue settings for each existing queue, and the additional queues will get the default setting. Signed-off-by:

When the user sets itr_setting to zero from ethtool -C, the driver changes this value to default in ice_cfg_itr (for example after changing ring param). Remove code that sets default value in ice_cfg_itr and move it to place where the driver allocates q_vectors. Signed-off-by:

Currently we do "for (i = 0; i < pf->num_alloc_vfs; i++)" all over the place. Many other places use macros to contain this repeated for loop, So create the macro ice_for_each_vf(pf, i) that does the same thing. There were a couple places we were using one loop variable and a VF iterator, which were changed to using a local variable within the ice_for_each_vf() macro. Also in ice_alloc_vfs() we were setting pf->num_alloc_vfs after doing "for (i = 0; i < num_alloc_vfs; i++)". Instead assign pf->num_alloc_vfs right after allocating memory for the pf->vf array.

We can't have more than one default VSI so prevent another VSI from overwriting the current dflt_vsi. This was achieved by adding the following functions: ice_is_dflt_vsi_in_use() - Used to check if the default VSI is already being used. ice_is_vsi_dflt_vsi() - Used to check if VSI passed in is in fact the default VSI. ice_set_dflt_vsi() - Used to set the default VSI via a switch rule ice_clear_dflt_vsi() - Used to clear the default VSI via a switch rule. Also, there was no need to introduce any locking because all mailbox events and synchronization of switch filters for the PF happen in the service task. Signed-off-by:

There are many things wrong with the function ice_set_vf_spoofchk(). 1. The VSI being modified is the PF VSI, not the VF VSI. 2. We are enabling Rx VLAN pruning instead of Tx VLAN anti-spoof. 3. The spoofchk setting for each VF is not initialized correctly or re-initialized correctly on reset. To fix [1] we need to make sure we are modifying the VF VSI. This is done by using the vf->lan_vsi_idx to index into the PF's VSI array. To fix [2] replace setting Rx VLAN pruning in ice_set_vf_spoofchk() with setting Tx VLAN anti-spoof. To Fix [3] we need to make sure the initial VSI settings match what is done in ice_set_vf_spoofchk() for spoofchk=on. Also make sure this also works for VF reset. This was done by modifying ice_vsi_init() to account for the current spoofchk state of the VF VSI. Because of these changes, Tx VLAN anti-spoof needs to be removed from ice_cfg_vlan_pruning(). This is okay for the VF because this is now controlled from the admin enabling/disabling spoofchk. For the PF, Tx VLAN anti-spoof should not be set. This change requires us to call ice_set_vf_spoofchk() when configuring promiscuous mode for the VF which requires ice_set_vf_spoofchk() to move in order to prevent a forward declaration prototype. Also, add VLAN 0 by default when allocating a VF since the PF is unaware if the guest OS is running the 8021q module. Without this, MDD events will trigger on untagged traffic because spoofcheck is enabled by default. Due to this change, ignore add/delete messages for VLAN 0 from VIRTCHNL since this is added/deleted during VF initialization/teardown respectively and should not be modified. Signed-off-by:
