2020-04-20ASoC: meson: gx-card: fix codec-to-codec link setupJerome Brunet1-1/+3
Since the addition of commit 9b5db059366a ("ASoC: soc-pcm: dpcm: Only allow playback/capture if supported"), meson-axg cards which have codec-to-codec links fail to init and Oops.

While this error was initially reported the axg-card type, it also applies to the gx-card type. While initiliazing the links, ASoC treats the codec-to-codec links of this card type as a DPCM backend.

The property "no_pcm" marking DCPM BE was left set on codec-to-codec links, leading to this problem. This commit fixes that.

2020-04-20KVM: s390: Fix PV check in deliverable_irqs()Eric Farman1-1/+1
The diag 0x44 handler, which handles a directed yield, goes into a a codepath that does a kvm_for_each_vcpu() and ultimately deliverable_irqs(). The new check for kvm_s390_pv_cpu_is_protected() contains an assertion that the vcpu->mutex is held, which isn't going to be the case in this scenario. The result is a plethora of these messages if the lock debugging is enabled, and thus an implication that we have a problem.

The case ACPI_RESOURCE_TYPE_EXTENDED_IRQ inside acpi_pci_link_set() is correctly using resource->res.data.extended_irq.foo for most settings, but for the shareable setting it so far has accidentally been using resource->res.data.irq.shareable instead of resource->res.data.extended_irq.shareable. Note that the old code happens to also work because the shareable field offset is the same for both the acpi_resource_irq and acpi_resource_extended_irq structs.

2020-04-20drm/tidss: fix crash related to accessing freed memoryTomi Valkeinen3-12/+42
tidss uses devm_kzalloc to allocate DRM plane, encoder and crtc objects. This is not correct as the lifetime of those objects should be longer than the underlying device's. When unloading tidss module, the devm_kzalloc'ed objects have already been freed when tidss_release() is called, and the driver will accesses freed memory possibly causing a crash, a kernel WARN, or other undefined behavior, and also KASAN will give a bug.

2020-04-20ALSA: usb-audio: Add static mapping table for ALC1220-VB-based mobosTakashi Iwai3-6/+44
TRX40 mobos from MSI and others with ALC1220-VB USB-audio device need yet more quirks for the proper control names. This patch provides the mapping table for those boards, correcting the FU names for volume and mute controls as well as the terminal names for jack controls. It also improves build_connector_control() not to add the directional suffix blindly if the string is given from the mapping table. With this patch applied, the new UCM profiles will be effective.

2020-04-20ALSA: hda: Remove ASUS ROG Zenith from the blacklistTakashi Iwai1-1/+0
The commit 3c6fd1f07ed0 ("ALSA: hda: Add driver blacklist") added a new blacklist for the devices that are known to have empty codecs, and one of the entries was ASUS ROG Zenith II (PCI SSID 1043:874f). However, it turned out that the very same PCI SSID is used for the previous model that does have the valid HD-audio codecs and the change broke the sound on it. This patch reverts the corresponding entry as a temporary solution. Although Zenith II and co will see get the empty HD-audio bus again, it'd be merely resource wastes and won't affect the functionality, so it's no end of the world. We'll need to address this later, e.g. by either switching to DMI string matching or using PCI ID & SSID pairs.

2020-04-20mm: Fix MREMAP_DONTUNMAP accounting on VMA mergeBrian Geffon1-1/+12
When remapping a mapping where a portion of a VMA is remapped into another portion of the VMA it can cause the VMA to become split. During the copy_vma operation the VMA can actually be remerged if it's an anonymous VMA whose pages have not yet been faulted. This isn't normally a problem because at the end of the remap the original portion is unmapped causing it to become split again. However, MREMAP_DONTUNMAP leaves that original portion in place which means that the VMA which was split and then remerged is not actually split at the end of the mremap. This patch fixes a bug where we don't detect that the VMAs got remerged and we end up putting back VM_ACCOUNT on the next mapping which is completely unreleated. When that next mapping is unmapped it results in incorrectly unaccounting for the memory which was never accounted, and eventually we will underflow on the memory comittment. There is also another issue which is similar, we're currently accouting for the number of pages in the new_vma but that's wrong. We need to account for the length of the remap operation as that's all that is being added. If there was a mapping already at that location its comittment would have been adjusted as part of the munmap at the start of the mremap. A really simple repro can be seen in: https://gist.github.com/bgaff/e101ce99da7d9a8c60acc641d07f312c Fixes: e346b3813067 ("mm/mremap: add MREMAP_DONTUNMAP to mremap()") Reported-by: syzbot <syzkaller@googlegroups.com> Signed-off-by: Brian Geffon <bgeffon@google.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The IGC_MAC_STATE_QUEUE_STEERING bit in mac_table[i].state is utilized to indicate that frames matching the filter are assigned to mac_table[i].queue. This bit is not strictly necessary since we can convey the same information as follows: queue == -1 means queue assignment is disabled, otherwise it is enabled. In addition to make the code simpler, this change fixes some awkward situations where we pass a complete misleading 'queue' value such as in igc_uc_sync().

2020-04-19igc: Refactor igc_rar_set_index()Andre Guedes1-31/+42
Current igc_rar_set_index() implementation is a bit convoluted so this patch does some code refactoring to improve it. The helper igc_rar_set_index() is about writing MAC filter settings into hardware registers. Logic such as address validation belongs to functions upper in the call chain such as igc_set_mac() and igc_add_mac_filter(). So this patch moves the is_valid_ether_addr() call to igc_add_mac_filter(). No need to touch igc_set_mac() since it already checks it. The variables 'rar_low' and 'rar_high' represent the value in registers RAL and RAH so we rename them to 'ral' and 'rah', respectively, to match the registers names. To make it explicit, filter settings are passed as arguments to the function instead of reading them from adapter->mac_table "under the hood". Also, the function was renamed to igc_set_mac_filter_hw to make it more clear what it does. Finally, the patch removes some wrfl() calls and comments not needed.

In fact, callers have extra code just to handle this returning index as 0 (success). So this patch changes the function to return 0 on success instead, and cleans up the extra code.

2020-04-19igc: Remove duplicate code in MAC filtering logicAndre Guedes1-99/+13
This patch does a code refactoring in the MAC address filtering logic to get rid of some duplicate code. IGC driver has two functions to add MAC address filters that are pretty much the same: igc_add_mac_filter() and igc_add_mac_filter_flags(). The only difference is that the latter allows the callee to specify the 'flags' parameter while the former has it hard coded as zero. The same rationale applies to filter deletion counterparts. So this patch refactors igc_add_mac_filter() and igc_del_mac_filter() so they handle the 'flags' parameters, removes the _flags() functions, and fixes callees accordingly.

Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member convertions) will also help to get completely rid of those sorts of issues.

2020-04-19enetc: permit configuration of rx-vlan-filter with ethtoolVladimir Oltean1-28/+16
Each ENETC station interface (SI) has a VLAN filter list and a port flag (PSIPVMR) by which it can be put in "VLAN promiscuous" mode, which enables the reception of VLAN-tagged traffic even if it is not in the VLAN filtering list. Currently the handling of this setting works like this: the port starts off as VLAN promiscuous, then it switches to enabling VLAN filtering as soon as the first VLAN is installed in its filter via .ndo_vlan_rx_add_vid. In practice that does not work out very well, because more often than not, the first VLAN to be installed is out of the control of the user: the 8021q module, if loaded, adds its rule for 802.1p (VID 0) traffic upon bringing the interface up. What the user is currently seeing in ethtool is this: ethtool -k eno2 rx-vlan-filter: on [fixed] which doesn't match the intention of the code, but the practical reality of having the 8021q module install its VID which has the side-effect of turning on VLAN filtering in this driver. All in all, a slightly confusing experience. So instead of letting this driver switch the VLAN filtering state by itself, just wire it up with the rx-vlan-filter feature from ethtool, and let it be user-configurable just through that knob, except for one case, see below. In promiscuous mode, it is more intuitive that all traffic is received, including VLAN tagged traffic. It appears that it is necessary to set the flag in PSIPVMR for that to be the case, so VLAN promiscuous mode is also temporarily enabled. On exit from promiscuous mode, the setting made by ethtool is restored.

2020-04-19net: mscc: ocelot: deal with problematic MAC_ETYPE VCAP IS2 rulesVladimir Oltean3-4/+106
By default, the VCAP IS2 will produce a single match for each frame, on the most specific classification. Example: a ping packet (ICMP over IPv4 over Ethernet) sent from an IP address of 10.0.0.1 and a MAC address of 96:18:82:00:04:01 will match this rule: tc filter add dev swp0 ingress protocol ipv4 \ flower skip_sw src_ip 10.0.0.1 action drop but not this one: tc filter add dev swp0 ingress \ flower skip_sw src_mac 96:18:82:00:04:01 action drop Currently the driver does not really warn the user in any way about this, and the behavior is rather strange anyway. The current patch is a workaround to force matches on MAC_ETYPE keys (DMAC and SMAC) for all packets irrespective of higher layer protocol. The setting is made at the port level. Of course this breaks all other non-src_mac and non-dst_mac matches, so rule exclusivity checks have been added to the driver, in order to never have rules of both types on any ingress port. The bits that discard higher-level protocol information are set only once a MAC_ETYPE rule is added to a filter block, and only for the ports that are bound to that filter block. Then all further non-MAC_ETYPE rules added to that filter block should be denied by the ports bound to it. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

Sasha adds partial generic segmentation offload (GSO partial) support to the igc driver. Also added support for translating taprio schedules into i225 cycles in igc. Did clean up of dead code or unused defines in the igc driver. Refactored the code to avoid forward declarations where possible. Enables the NETIF_F_HW_TC flag for igc by default. Vinicius adds support for ETF offloading using the similar approach that taprio offload used. Kees Cook fixes a clang warning in the e1000e driver by moving the declared variable either into the switch case that uses the variable or lift them up into the main function body, to help the compiler. Andre fixed some register overwriting when dumping registers via ethtool for igc driver. Also fixed support for ethtool Network Flow Classification (NFC) queue redirection by adding the missing code needed to enable the queue selection feature from Receive Address High (RAH) register. Cleans up code to remove the code bits designed to support tc-flower filters, since this client part does not support it. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
