qlge_fix_features() is not supposed to modify hardware or driver state, rather it is supposed to only fix requested fetures bits. Currently qlge_fix_features() also goes for interface down and up unnecessarily if there is not even any change in features set. This patch changes/fixes following - 1) Move reload of interface or device re-config from qlge_fix_features() to qlge_set_features(). 2) Reload of interface in qlge_set_features() only if relevant feature bit (NETIF_F_HW_VLAN_CTAG_RX) is changed. 3) Get rid of qlge_fix_features() since driver is not really required to fix any features bit.

macb_reset_hw() is called from macb_close() and indirectly from macb_open(). macb_reset_hw() zeroes the NCR register, including the MPE (Management Port Enable) bit. This will prevent accessing any other PHYs for other Ethernet MACs on the MDIO bus, which remains registered at macb_reset_hw() time, until macb_init_hw() is called from macb_open() which sets the MPE bit again. I.e. currently the MDIO bus has a short disruption at open time and is disabled at close time until the interface is opened again. Fix that by only touching the RE and TE bits when enabling and disabling RX/TX. v2: Make macb_init_hw() NCR write a single statement.

commit 739de9a1 ("net: macb: Reorganize macb_mii bringup") broke initializing macb on the EVB-KSZ9477 eval board. There, of_mdiobus_register was called even for the fixed-link representing the RGMII-link to the switch with the result that the driver attempts to enumerate PHYs on a non-existent MDIO bus: libphy: MACB_mii_bus: probed mdio_bus f0028000.ethernet-ffffffff: fixed-link has invalid PHY address mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 0 [snip] mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 31 The "MDIO" bus registration succeeds regardless, having claimed the reset GPIO, and calling of_phy_register_fixed_link later on fails because it tries to claim the same GPIO: macb f0028000.ethernet: broken fixed-link specification Fix this by registering the fixed-link before calling mdiobus_register.

When a bridge device is removed, the VLANs are flushed from each configured port. This causes the ports to decrement the reference count on the associated FIDs (filtering identifier). If the reference count of a FID is 1 and it has a RIF (router interface), then this RIF is destroyed. However, if no port is member in the VLAN for which a RIF exists, then the RIF will continue to exist after the removal of the bridge. To reproduce: # ip link add name br0 type bridge vlan_filtering 1 # ip link set dev swp1 master br0 # ip link add link br0 name br0.10 type vlan id 10 # ip address add 192.0.2.0/24 dev br0.10 # ip link del dev br0 The RIF associated with br0.10 continues to exist. Fix this by iterating over all the bridge device uppers when it is destroyed and take care of destroying their RIFs.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2018-08-24 This series contains fixes to e1000, igb, ixgb, ixgbe and i40e. YueHaibing from Huawei provides a change to use dma_zalloc_coherent() instead of calls to allocator followed by a memset for ixgb. Bo Chen provides a couple of fixes for e1000, first by adding a check to prevent a NULL pointer dereference. The second change is to clean up a possible resource leak on old transmit and receive rings when the device is not up. Jesus fixes an issue in the usage of an advanced transmit context descriptor for retrieving the timestamp of a packet for AF_PACKET if the IGB_TX_FLAGS_VLAN is not set in igb. Jia-Ju Bai provides several patches which replace GFP_ATOMIC with GFP_KERNEL, when using kzalloc() and kcalloc() which is not necessary. Also found an instance of mdelay() call which could be replaced with msleep(). Tony fixes ixgbe to allow MTU changes with XDP, by adding checks to ensure only supported values and return -EINVAL for when it is not supported. Sebastian fixed an issue that was not clearing VF mailbox memory and ensure queues are re-enabled correctly. Martyna fixes a transmit timeout when DCB is configured when bringing up an interface. Jake fixes a previous commit which accidentally reversed the check of the data pointer, so we can accurately count the size of the stats. ==================== Signed-off-by: NDavid S.

由 Jesus Sanchez-Palencia 提交于
On i210, Launchtime (TxTime) requires the usage of an "Advanced Transmit Context Descriptor" for retrieving the timestamp of a packet. The igb driver correctly builds such descriptor on the segmentation flow (i.e. igb_tso()) or on the checksum one (i.e. igb_tx_csum()), but the feature is broken for AF_PACKET if the IGB_TX_FLAGS_VLAN is not set, which happens due to an early return on igb_tx_csum(). This flag is only set by the kernel when a VLAN interface is used, thus we can't just rely on it. Here we are fixing this issue by checking if launchtime is enabled for the current tx_ring before performing the early return.

Anirudh provides several fixes, starting with static analysis fixes by replacing a bitwise-and with a constant value and replace "magic" numbers with defines. Fixed the control queue processing by removing unnecessary read/writes to registers, as well as getting a accurate value for "pending". Added additional checks to avoid NULL pointer dereferences. Fixed up code formatting issues, by cleaning up code comments and coding style. Bruce cleans up a duplicate check for owner, within the same function. Also cleans up interrupt causes that are not handled or applicable. Fix checkpatch warning about the use of bool in structures due to the wasted space and size of bool, so convert struct members to u8 instead. Jake fixes a number of potential bugs in the reporting of stats via ethtool, by simply reporting all the queue statistics, even for the queues that are not activated. Fixed a compiler warning, as well as make the code a bit cleaner but just using order_base_2() for calculating the power-of-2. Preethi adds a check to avoid a NULL pointer dereference crash during initialization.

Currently, we use a combination of ilog2 and is_power_of_2() to calculate the next power of 2 for the qcount. This appears to be causing a warning on some combinations of GCC and the Linux kernel: MODPOST 1 modules WARNING: "____ilog2_NaN" [ice.ko] undefined! This appears to because because GCC realizes that qcount could be zero in some circumstances and thus attempts to link against the intentionally undefined ___ilog2_NaN function. The order_base_2 function is intentionally defined to return 0 when passed 0 as an argument, and thus will be safe to use here. This not only fixes the warning but makes the resulting code slightly cleaner, and is really what we should have used originally. Also update the comment to make it more clear that we are rounding up, not just incrementing the ilog2 of qcount unconditionally.

由 Jacob Keller 提交于
It is not safe to have the string table for statistics change order or size over the lifetime of a given netdevice. This is because of the nature of the 3-step process for obtaining stats. First, user space performs a request for the size of the strings table. Second it performs a separate request for the strings themselves, after allocating space for the table. Third, it requests the stats themselves, also allocating space for the table. If the size decreased, there is potential to see garbage data or stats values. In the worst case, we could potentially see stats values become mis-aligned with their strings, so that it looks like a statistic is being reported differently than it actually is. Even worse, if the size increased, there is potential that the strings table or stats table was not allocated large enough and the stats code could access and write to memory it should not, potentially resulting in undefined behavior and system crashes. It isn't even safe if the size always changes under the RTNL lock. This is because the calls take place over multiple user space commands, so it is not possible to hold the RTNL lock for the entire duration of obtaining strings and stats. Further, not all consumers of the ethtool API are the user space ethtool program, and it is possible that one assumes the strings will not change (valid under the current contract), and thus only requests the stats values when requesting stats in a loop. Finally, it's not possible in the general case to detect when the size changes, because it is quite possible that one value which could impact the stat size increased, while another decreased. This would result in the same total number of stats, but reordering them so that stats no longer line up with the strings they belong to. Since only size changes aren't enough, we would need some sort of hash or token to determine when the strings no longer match. This would require extending the ethtool stats commands, but there is no more space in the relevant structures. The real solution to resolve this would be to add a completely new API for stats, probably over netlink. In the ice driver, the only thing impacting the stats that is not constant is the number of queues. Instead of reporting stats for each used queue, report stats for each allocated queue. We do not change the number of queues allocated for a given netdevice, as we pass this into the alloc_etherdev_mq() function to set the num_tx_queues and num_rx_queues. This resolves the potential bugs at the slight cost of displaying many queue statistics which will not be activated.

When enable the config item "CONFIG_ARM64_64K_PAGES", the size of PAGE_SIZE is 65536(64K). But the type of page_offset is u16, it will overflow. So change it to u32, when "CONFIG_ARM64_64K_PAGES" enabled.

Commit 6edb3c96 ("net/ipv6: Defer initialization of dst to data path") forgot to handle anycast route and init anycast rt->dst.input to ip6_forward. Fix it by setting anycast rt->dst.input back to ip6_input.
