2021-08-26cxgb4: dont touch blocked freelist bitmap after freeRahul Lakkireddy1-4/+3
When adapter init fails, the blocked freelist bitmap is already freed up and should not be touched. So, move the bitmap zeroing closer to where it was successfully allocated. Also handle adapter init failure unwind path immediately and avoid setting up RDMA memory windows.

The series "PCI/VPD: Convert more users to the new VPD API functions" was applied to net-next when it should have been applied to the PCI tree because of build errors. However, commit 82e34c8a9bdf ("Revert "Revert "cxgb4: Search VPD with pci_vpd_find_ro_info_keyword()""") reapplied a change, resulting in the warning above. Properly revert commit 8d63ee602da3 ("cxgb4: Search VPD with pci_vpd_find_ro_info_keyword()") to fix the warning and restore proper functionality. This also reverts commit 3a93bedea050 ("cxgb4: Remove unused vpd_param member ec") to avoid future merge conflicts, as that change has been applied to the PCI tree.

2021-08-13ethernet: fix PTP_1588_CLOCK dependenciesArnd Bergmann1-0/+1
The 'imply' keyword does not do what most people think it does, it only politely asks Kconfig to turn on another symbol, but does not prevent it from being disabled manually or built as a loadable module when the user is built-in. In the ICE driver, the latter now causes a link failure: aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_eth_ioctl': ice_main.c:(.text+0x13b0): undefined reference to `ice_ptp_get_ts_config' ice_main.c:(.text+0x13b0): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_get_ts_config' aarch64-linux-ld: ice_main.c:(.text+0x13bc): undefined reference to `ice_ptp_set_ts_config' ice_main.c:(.text+0x13bc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_set_ts_config' aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_prepare_for_reset': ice_main.c:(.text+0x31fc): undefined reference to `ice_ptp_release' ice_main.c:(.text+0x31fc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_release' aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_rebuild': This is a recurring problem in many drivers, and we have discussed it several times befores, without reaching a consensus. I'm providing a link to the previous email thread for reference, which discusses some related problems. To solve the dependency issue better than the 'imply' keyword, introduce a separate Kconfig symbol "CONFIG_PTP_1588_CLOCK_OPTIONAL" that any driver can depend on if it is able to use PTP support when available, but works fine without it. Whenever CONFIG_PTP_1588_CLOCK=m, those drivers are then prevented from being built-in, the same way as with a 'depends on PTP_1588_CLOCK || !PTP_1588_CLOCK' dependency that does the same trick, but that can be rather confusing when you first see it. Since this should cover the dependencies correctly, the IS_REACHABLE() hack in the header is no longer needed now, and can be turned back into a normal IS_ENABLED() check. Any driver that gets the dependency wrong will now cause a link time failure rather than being unable to use PTP support when that is in a loadable module. However, the two recently added ptp_get_vclocks_index() and ptp_convert_timestamp() interfaces are only called from builtin code with ethtool and socket timestamps, so keep the current behavior by stubbing those out completely when PTP is in a loadable module. This should be addressed properly in a follow-up. As Richard suggested, we may want to actually turn PTP support into a 'bool' option later on, preventing it from being a loadable module altogether, which would be one way to solve the problem with the ethtool interface.

Most users of ndo_do_ioctl are ethernet drivers that implement the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP. Separate these from the few drivers that use ndo_do_ioctl to implement SIOCBOND, SIOCBR and SIOCWANDEV commands.

2021-07-08cxgb4: fix IRQ free race during driver unloadShahjada Abul Husain2-8/+13
IRQs are requested during driver's ndo_open() and then later freed up in disable_interrupts() during driver unload. A race exists where driver can set the CXGB4_FULL_INIT_DONE flag in ndo_open() after the disable_interrupts() in driver unload path checks it, and hence misses calling free_irq(). Fix by unregistering netdevice first and sync with driver's ndo_open(). This ensures disable_interrupts() checks the flag correctly and frees up the IRQs properly.

2021-06-03net:cxgb3: replace tasklets with worksÍñigo Huguet3-17/+25
OFLD and CTRL TX queues can be stopped if there is no room in their DMA rings. If this happens, they're tried to be restarted later after having made some room in the corresponding ring. The tasks of restarting these queues were triggered using tasklets, but they can be replaced for workqueue works, getting them out of softirq context. This queues stop/restart probably doesn't happen often and they can be quite lengthy because they try to send all pending skbs. Moreover, given that probably the ring is not empty yet, so the DMA still has work to do, we don't need to be so fast to justify using tasklets/softirq instead of running in a thread.
