* cns3xxx: fix writing to wrong PCI registersKoen Vandeputte2018-12-181-0/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, cns3xxx used it's own functions for mapping, reading and writing registers. Upstream commit 802b7c06adc7 ("ARM: cns3xxx: Convert PCI to use generic config accessors") removed the internal PCI config write function in favor of the generic one: cns3xxx_pci_write_config() --> pci_generic_config_write() cns3xxx_pci_write_config() expected aligned addresses, being produced by cns3xxx_pci_map_bus() while the generic one pci_generic_config_write() actually expects the real address as both the function and hardware are capable of byte-aligned writes. This currently leads to pci_generic_config_write() writing to the wrong registers on some ocasions. First issue seen due to this: - driver ath9k gets loaded - The driver wants to write value 0xA8 to register PCI_LATENCY_TIMER, located at 0x0D - cns3xxx_pci_map_bus() aligns the address to 0x0C - pci_generic_config_write() effectively writes 0xA8 into register 0x0C (CACHE_LINE_SIZE) This seems to cause some slight instability when certain PCI devices are used. Another issue example caused by this this is the PCI bus numbering, where the primary bus is higher than the secondary, which is impossible. Before: 00:00.0 PCI bridge: Cavium, Inc. Device 3400 (rev 01) (prog-if 00 [Normal decode]) Flags: bus master, fast devsel, latency 0, IRQ 255 Bus: primary=02, secondary=01, subordinate=ff, sec-latency=0 After fix: 00:00.0 PCI bridge: Cavium, Inc. Device 3400 (rev 01) (prog-if 00 [Normal decode]) Flags: bus master, fast devsel, latency 0, IRQ 255 Bus: primary=00, secondary=01, subordinate=02, sec-latency=0 And very likely some more .. Fix all by omitting the alignment being done in the mapping function. Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com>
* kernel: preserve oif of IPv6 link scope packetsHans Dedecker2018-12-171-0/+32
| | | | | | | | | | | Backort upstream patch which preserves oif of IPv6 link scoped packets. The outgoing interface of IPv6 link scope packets can be changed by the function ip6_route_me_harder. This is unwanted behavior for link local packets and multicast packets as the outgoing interface is fixed and must not be altered as it can break neighbor discovery and multicast listener discovery.

* kernel: backport ifconfig ioctl support for class e addressesKevin Darbyshire-Bryant2018-12-171-0/+79
| | | | | | | | | | | | | | | | | Backport net: Allow class-e address assignment via ifconfig ioctl While most distributions long ago switched to the iproute2 suite of utilities, which allow class-e (240.0.0.0/4) address assignment, distributions relying on busybox, toybox and other forms of ifconfig cannot assign class-e addresses without this kernel patch. While CIDR has been obsolete for 2 decades, and a survey of all the open source code in the world shows the IN_whatever macros are also obsolete... rather than obsolete CIDR from this ioctl entirely, this patch merely enables class-e assignment, sanely. https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=65cab850f0eeaa9180bd2e10a231964f33743edf Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
* kernel: mv88e6060: disable hardware level MAC learningAnderson Luiz Alves2018-12-161-0/+44
| | | | | | | | | | | | | | | | Disable Marvell's hardware level MAC learning because it breaks station roaming. When enabled it drops all frames that arrive from a MAC address that is on a different port at learning table. Problem description: Multiple APs with inter-AP roaming connected to different ports, when station moves from one AP on one port to another AP on another port, traffic flow breaks down because the learning table is not updated.

* kernel: Make the patches apply on top of 4.19Hauke Mehrtens2018-12-15106-18012/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the patches which were just copied in the previous commit apply on top of kernel 4.19. The patches in the backports-4.19 folder were checked if they are really in kernel 4.19 based on the title and only removed if they were found in the upstream kernel. The following additional patches form the pending folder went into upstream Linux 4.19: pending-4.19/171-usb-dwc2-Fix-inefficient-copy-of-unaligned-buffers.patch pending-4.19/190-2-5-e1000e-Fix-wrong-comment-related-to-link-detection.patch pending-4.19/478-mtd-spi-nor-Add-support-for-XM25QH64A-and-XM25QH128A.patch pending-4.19/479-mtd-spi-nor-add-eon-en25qh32.patch pending-4.19/950-tty-serial-exar-generalize-rs485-setup.patch pending-4.19/340-MIPS-mm-remove-mips_dma_mapping_error.patch Bigger changes were introduced to the m25p80 spi nor driver, as far as I saw it in the new code, it now has the functionality provided in this patch: pending-4.19/450-mtd-m25p80-allow-fallback-from-spi_flash_read-to-reg.patch Part of this patch went upstream independent of OpenWrt: hack-4.19/220-gc_sections.patch This patch was reworked to match the changes done upstream. The MIPS DMA API changed a lot, this patch was rewritten to match the new DMA handling: pending-4.19/341-MIPS-mm-remove-no-op-dma_map_ops-where-possible.patch I did bigger manual changes to the following patches and I am not 100% sure if they are all correct: pending-4.19/0931-w1-gpio-fix-problem-with-platfom-data-in-w1-gpio.patch pending-4.19/411-mtd-partial_eraseblock_write.patch pending-4.19/600-netfilter_conntrack_flush.patch pending-4.19/611-netfilter_match_bypass_default_table.patch pending-4.19/670-ipv6-allow-rejecting-with-source-address-failed-policy.patch hack-4.19/211-host_tools_portability.patch hack-4.19/221-module_exports.patch hack-4.19/321-powerpc_crtsavres_prereq.patch hack-4.19/902-debloat_proc.patch This is based on patchset from Marko Ratkaj <marko.ratkaj@sartura.hr> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
