The Global (1) internal SMI device is an extended set of registers containing ATU, PPU, VTU, STU, etc. It is present on every switches, usually at SMI address 0x1B. But old models such as 88E6060 access it at address 0xF, thus using REG_GLOBAL is erroneous. Add a global1_addr info member used by mv88e6xxx_g1_{read,write} and mv88e6xxx_g1_wait helpers in a new global1.c file. This patch finally removes _mv88e6xxx_reg_{read,write}, in favor on the appropriate helpers. No functional changes here.

Timur Tabi says: ==================== Add basic ACPI support to the Qualcomm Technologies EMAC driver This patch series adds support to the EMAC driver for extracting addresses, interrupts, and some _DSDs (properties) from ACPI. The first two patches clean up the code, and the third patch adds ACPI-specific functionality. The first patch fixes a bug with handling the platform_device for the internal PHY. This phy is treated as a separate device in both DT and ACPI, but since the platform is not released automatically when the driver unloads, managed functions like devm_ioremap_resource cannot be used. The second patch replaces of_get_mac_address with its platform-independent equivalent device_get_mac_address. The third patch parses the ACPI tables to obtain the platform_device for the primary EMAC node ("QCOM8070") and the internal phy node ("QCOM8071"). ==================== Signed-off-by: David S.

Add support for reading addresses, interrupts, and _DSD properties from ACPI tables, just like with device tree. The HID for the EMAC device itself is QCOM8070. The internal PHY is represented by a child node with a HID of QCOM8071. The EMAC also has some complex clock initialization requirements that are not represented by this patch. This will be addressed in a future patch. Signed-off-by: Timur Tabi <timur@codeaurora.org> Signed-off-by: David S. Miller <davem@davemloft.net>

The platform_device returned by of_find_device_by_node() is not automatically released when the driver unprobes. Therefore, managed calls like devm_ioremap_resource() should not be used. Instead, we manually allocate the resources and then free them on driver release. Signed-off-by: Timur Tabi <timur@codeaurora.org> Signed-off-by: David S. Miller <davem@davemloft.net>

Suppose you have a map array value that is something like this struct foo { unsigned iter; int array[SOME_CONSTANT]; }; You can easily insert this into an array, but you cannot modify the contents of foo->array[] after the fact. This is because we have no way to verify we won't go off the end of the array at verification time. This patch provides a start for this work. We accomplish this by keeping track of a minimum and maximum value a register could be while we're checking the code. Then at the time we try to do an access into a MAP_VALUE we verify that the maximum offset into that region is a valid access into that memory region. So in practice, code such as this unsigned index = 0; if (foo->iter >= SOME_CONSTANT) foo->iter = index; else index = foo->iter++; foo->array[index] = bar; would be allowed, as we can verify that index will always be between 0 and SOME_CONSTANT-1. If you wish to use signed values you'll have to have an extra check to make sure the index isn't less than 0, or do something like index %= SOME_CONSTANT.

The current code changes txhash (flowlables) on every retransmitted SYN/ACK, but only after the 2nd retransmitted SYN and only after tcp_retries1 RTO retransmits. With this patch: 1) txhash is changed with every SYN retransmits 2) txhash is changed with every RTO. The result is that we can start re-routing around failed (or very congested paths) as soon as possible. Otherwise application health checks may fail and the connection may be terminated before we start to change txhash. v4: Removed sysctl, txhash is changed for all RTOs v3: Removed text saying default value of sysctl is 0 (it is 100) v2: Added sysctl documentation and cleaned code Tested with packetdrill tests Signed-off-by: Lawrence Brakmo <brakmo@fb.com> Signed-off-by: David S.

Jiri Pirko says: ==================== fib offload: switch to notifier The goal of this patchset is to allow driver to propagate all prefixes configured in kernel down HW. This is necessary for routing to work as expected. If we don't do that HW might forward prefixes known to kernel incorrectly. Take an example when default route is set in switch HW and there is an IP address set on a management (non-switch) port. Currently, only FIB entries related to the switch port netdev are offloaded using switchdev ops. This model is not extendable so the first patch introduces a replacement: notifier to propagate FIB entry additions and removals to whoever is interested. The second patch introduces couple of helpers to deal with RTNH_F_OFFLOAD flags. Currently it is set in switchdev core. There the assumption is that only one offload device exists. But for FIB notifier, we assume multiple offload devices. So the patch introduces a per FIB entry reference counter and helpers use it in order to achieve this: 0 means RTNH_F_OFFLOAD is not set, no device offloads this entry n means RTNH_F_OFFLOAD is set and the entry is offloaded by n devices Patches 3 and 4 convert mlxsw and rocker to adopt this new way, registering one notifier block for each asic instance. Both of these patches also implement internal "abort" mechanism. Using switchdev ops, "abort" is called by switchdev core whenever there is an error during FIB entry add offload. This leads to removal of all offloaded entries on system by fib_trie code. Now the new notifier assumes the driver takes care of the abort action. Here's why: 1) The fact that one HW cannot offload an entry does not mean that the others can't do it. So let only one entity to abort and leave the rest to work happily. 2) The driver knows what to in order to properly abort. For example, currently abort is broken for mlxsw, as for Spectrum there is a need to set 0.0.0.0/0 trap in RALUE register. The fifth patch removes the old, no longer used FIB offload infrastructure. The last patch reflects the changes into switchdev documentation file. --- v2->v3: -patch 3/6 -fixed offload inc/dec to be done in fib4_entry_init/fini and only in case !trap as suggested by Ido v1->v2: -patch 3/6: -fixed lpm tree setup and binding for abort and pointed out by Ido -do nexthop checks as suggested by Ido -fix use after free during abort -patch 6/6: -fixed texts as suggested by Ido ==================== Signed-off-by: David S.

Until now, in order to offload a FIB entry to HW we use switchdev op. However that has limits. Mainly in case we need to make the HW aware of all route prefixes configured in kernel.

Philippe Reynes says: ==================== net: bcmgenet: only use new api ethtool_{get|set}_link_ksettings Some times ago, a serie of patches were committed : - commit 62469c76 ("net: ethernet: bcmgenet: use phydev from struct net_device") - commit 6b352ebc ("net: ethernet: broadcom: bcmgenet: use new api ethtool_{get|set}_link_ksettings") The first patch add a regression on this driver, so it should be reverted. As the second patch depend on the former, it should be reverted too. The first patch is buggy because there is a "trick" in this driver. The structure phydev is kept in the private data when the interface go down, and used when the interface go up to enable the phy before the function phy_connect is called. I don't have this hardware, neither the datasheet. So I won't update the driver to avoid this trick. But the real goal of the first serie was to move to the new api ethtool_{get|set}_link_ksettings. So I provide a new version of the patch without the "cleaning" of driver to use the phydev store in the net_device structure.

This reverts commit 62469c76 ("net: ethernet: bcmgenet: use phydev from struct net_device") because it causes GENETv1/2/3 adapters to expose the following behavior after an ifconfig down/up sequence: PING fainelli-linux (10.112.156.244): 56 data bytes 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.352 ms 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.472 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.496 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.517 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.536 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.557 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=752.448 ms (DUP!) This was previously fixed by commit 5dbebbb4 ("net: bcmgenet: Software reset EPHY after power on") but the commit we are reverting was essentially making this previous commit void, here is why. Without commit 62469c76 we would have the following scenario after an ifconfig down then up sequence: - bcmgenet_open() calls bcmgenet_power_up() to make sure the PHY is initialized *before* we get to initialize the UniMAC, this is critical to ensure the PHY is in a correct state, priv->phydev is valid, this code executes fine - second time from bcmgenet_mii_probe(), through the normal phy_init_hw() call (which arguably could be optimized out) Everything is fine in that case. With commit 62469c76, we would have the following scenario to happen after an ifconfig down then up sequence: - bcmgenet_close() calls phy_disonnect() which makes dev->phydev become NULL - when bcmgenet_open() executes again and calls bcmgenet_mii_reset() from bcmgenet_power_up() to initialize the internal PHY, the NULL check becomes true, so we do not reset the PHY, yet we keep going on and initialize the UniMAC, causing MAC activity to occur - we call bcmgenet_mii_reset() from bcmgenet_mii_probe(), but this is too late, the PHY is botched, and causes the above bogus pings/packets transmission/reception to occur Reported-by: Jaedon Shin <jaedon.shin@gmail.com> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Philippe Reynes <tremyfr@gmail.com> Signed-off-by: David S.

This prevent future potential pointer leaks when an unprivileged eBPF program will read a pointer value from its context. Even if is_valid_access() returns a pointer type, the eBPF verifier replace it with UNKNOWN_VALUE. The register value that contains a kernel address is then allowed to leak. Moreover, this fix allows unprivileged eBPF programs to use functions with (legitimate) pointer arguments. Not an issue currently since reg_type is only set for PTR_TO_PACKET or PTR_TO_PACKET_END in XDP and TC programs that can only be loaded as privileged. For now, the only unprivileged eBPF program allowed is for socket filtering and all the types from its context are UNKNOWN_VALUE. However, this fix is important for future unprivileged eBPF programs which could use pointers in their context.

Currently, we can have high order page allocations that specify GFP_ATOMIC when configuring multicast MAC address filters. For example, we have seen order 2 page allocation failures with ~500 multicast addresses configured. Convert the allocation for 'mcast_list' to be done in PAGE_SIZE increments.
