Currently, intel_pstate_update_perf_limits() first converts the policy minimum and maximum limits into percentages of the maximum turbo frequency (rounding up to an integer) and then converts these percentages to fractions (by using fixed-point arithmetic to divide them by 100). That introduces a rounding error unnecessarily, because the fractions can be obtained by carrying out fixed-point divisions directly on the input numbers. Rework the computations in intel_pstate_hwp_set() to use fractions instead of percentages (and drop redundant local variables from there) and modify intel_pstate_update_perf_limits() to compute the fractions directly and percentages out of them. While at it, introduce percent_ext_fp() for converting percentages to fractions (with extended number of fraction bits) and use it in the computations. Signed-off-by: Rafael J.

Reviewing the result of what was just added for Kconfig, we made a poor choice. It worked well for full kernel builds, but not so much for how it would be deployed on a distro. Here's the final result: - lpfc will compile in NVME initiator and/or NVME target support based on whether the kernel has the corresponding subsystem support. Kconfig is not used to drive this specifically for lpfc. - There is a module parameter, lpfc_enable_fc4_type, that indicates whether the ports will do FCP-only or FCP & NVME (NVME-only not yet possible due to dependency on fc transport). As FCP & NVME divvys up exchange resources, and given NVME will not be often initially, the default is changed to FCP only.

This was added to allow the TC offloading code to identify offloading encap/decap vxlan rules. The VF reps are effectively related to the same mlx5 PCI device as the PF. Since the kernel invokes the (say) delete ndo for each netdev, the FW erred on multiple vxlan dst port deletes when the port was deleted from the system. We fix that by keeping the registration to be carried out only by the PF. Since the PF serves as the uplink device, the VF reps will look up a port there and realize if they are ok to offload that.

Commit 6ac3ce8 ("net: bcmgenet: Remove excessive PHY reset") removed the bcmgenet_mii_reset() function from bcmgenet_power_up() and bcmgenet_internal_phy_setup() functions. In so doing it broke the reset of the internal PHY devices used by the GENETv1-GENETv3 which required this reset before the UniMAC was enabled. It also broke the internal GPHY devices used by the GENETv4 because the config_init that installed the AFE workaround was no longer occurring after the reset of the GPHY performed by bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup(). In addition the code in bcmgenet_internal_phy_setup() related to the "enable APD" comment goes with the bcmgenet_mii_reset() so it should have also been removed. Commit bd4060a ("net: bcmgenet: Power on integrated GPHY in bcmgenet_power_up()") moved the bcmgenet_phy_power_set() call to the bcmgenet_power_up() function, but failed to remove it from the bcmgenet_internal_phy_setup() function. Had it done so, the bcmgenet_internal_phy_setup() function would have been empty and could have been removed at that time. Commit 5dbebbb ("net: bcmgenet: Software reset EPHY after power on") was submitted to correct the functional problems introduced by commit 6ac3ce8 ("net: bcmgenet: Remove excessive PHY reset"). It was included in v4.4 and made available on 4.3-stable. Unfortunately, it didn't fully revert the commit because this bcmgenet_mii_reset() doesn't apply the soft reset to the internal GPHY used by GENETv4 like the previous one did. This prevents the restoration of the AFE work- arounds for internal GPHY devices after the bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup(). This commit takes the alternate approach of removing the unnecessary bcmgenet_internal_phy_setup() function which shouldn't have been in v4.3 so that when bcmgenet_mii_reset() was restored it should have only gone into bcmgenet_power_up(). This will avoid the problems while also removing the redundancy (and hopefully some of the confusion).

In both kmalloc and prealloc mode the bpf_map_update_elem() is using per-cpu extra_elems to do atomic update when the map is full. There are two issues with it. The logic can be misused, since it allows max_entries+num_cpus elements to be present in the map. And alloc_extra_elems() at map creation time can fail percpu alloc for large map values with a warn: WARNING: CPU: 3 PID: 2752 at ../mm/percpu.c:892 pcpu_alloc+0x119/0xa60 illegal size (32824) or align (8) for percpu allocation The fixes for both of these issues are different for kmalloc and prealloc modes. For prealloc mode allocate extra num_possible_cpus elements and store their pointers into extra_elems array instead of actual elements. Hence we can use these hidden(spare) elements not only when the map is full but during bpf_map_update_elem() that replaces existing element too. That also improves performance, since pcpu_freelist_pop/push is avoided. Unfortunately this approach cannot be used for kmalloc mode which needs to kfree elements after rcu grace period. Therefore switch it back to normal kmalloc even when full and old element exists like it was prior to commit 6c90598 ("bpf: pre-allocate hash map elements"). Add tests to check for over max_entries and large map values.

In sk_clone_lock(), we create a new socket and inherit most of the parent's members via sock_copy() which memcpy()'s various sections. Now, in case the parent socket had a BPF socket filter attached, then newsk->sk_filter points to the same instance as the original sk->sk_filter. sk_filter_charge() is then called on the newsk->sk_filter to take a reference and should that fail due to hitting max optmem, we bail out and release the newsk instance. The issue is that commit 278571b ("net: filter: simplify socket charging") wrongly combined the dismantle path with the failure path of xfrm_sk_clone_policy(). This means, even when charging failed, we call sk_free_unlock_clone() on the newsk, which then still points to the same sk_filter as the original sk. Thus, sk_free_unlock_clone() calls into __sk_destruct() eventually where it tests for present sk_filter and calls sk_filter_uncharge() on it, which potentially lets sk_omem_alloc wrap around and releases the eBPF prog and sk_filter structure from the (still intact) parent. Fix it by making sure that when sk_filter_charge() failed, we reset newsk->sk_filter back to NULL before passing to sk_free_unlock_clone(), so that we don't mess with the parents sk_filter. Only if xfrm_sk_clone_policy() fails, we did reach the point where either the parent's filter was NULL and as a result newsk's as well or where we previously had a successful sk_filter_charge(), thus for that case, we do need sk_filter_uncharge() to release the prior taken reference on sk_filter.

Commit 2ae0f17 ("genetlink: use idr to track families") replaced if (++n < fams_to_skip) continue; into: if (n++ < fams_to_skip) continue; This subtle change cause that on retry ctrl_dumpfamily() call we omit one family that failed to do ctrl_fill_info() on previous call, because cb->args[0] = n number counts also family that failed to do ctrl_fill_info(). Patch fixes the problem and avoid confusion in the future just decrease n counter when ctrl_fill_info() fail. User visible problem caused by this bug is failure to get access to some genetlink family i.e. nl80211. However problem is reproducible only if number of registered genetlink families is big enough to cause second call of ctrl_dumpfamily().

compile-testing fails when QCOM_SMD is a loadable module: drivers/bluetooth/built-in.o: In function `btqcomsmd_send': btqca.c:(.text+0xa8): undefined reference to `qcom_smd_send' drivers/bluetooth/built-in.o: In function `btqcomsmd_probe': btqca.c:(.text+0x3ec): undefined reference to `qcom_wcnss_open_channel' btqca.c:(.text+0x46c): undefined reference to `qcom_smd_set_drvdata' This clarifies the dependency to allow compile-testing only when SMD is completely disabled, otherwise the dependency on QCOM_SMD will make sure we can link against it.

Presumably if there is an "add" function, there is also a "del" function. But it causes a static checker warning because it looks like a common cut and paste bug.

The ECC bit positions that describe whether the ECC interrupt is for Tx, Rx or descriptor memory and whether the it is a single correctable or double detected error were defined in incorrectly (reversed order). Fix the bit position definitions for these settings so that the proper ECC handling is performed. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S.
