* ixl(4): Report RX errors as sum of all RX error countersKrzysztof Galazka2021-03-031-7/+9
| | | | | | | | | | | | | | | | | | HW keeps track of RX errors using several counters, each for specific type of errors. Report RX errors to OS as sum of all those counters: CRC errors, illegal bytes, checksum, length, undersize, fragment, oversize and jabber errors. There is no HW counter for frames with invalid L3/L4 checksums so add a SW one. Also add a "rx_errors" sysctl with a copy of netstat IERRORS counter value to make it easier accessible from scripts.

| | | | | | | | | | | | r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags.

* intel iflib drivers: correct initialization of tx_cidx_processedEric Joyner2019-01-241-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From Jake: In r341156 ("Fix first-packet completion", 2018-11-28) a hack to work around a delta calculation determining how many descriptors were used was added to ixl_isc_tx_credits_update_dwb. The same fix was also applied to the em and igb drivers in r340310, and to ix in r341156. The hack checked the case where prev and cur were equal, and then added one. This works, because by the time we do the delta check, we already know there is at least one packet available, so the delta should be at least one. However, it's not a complete fix, and as indicated by the comment is really a hack to work around the real bug. The real problem is that the first time that we transmit a packet, tx_cidx_processed will be set to point to the start of the ring. Ultimately, the credits_update function expects it to point to the *last* descriptor that was processed. Since we haven't yet processed any descriptors, pointing it to 0 results in this incorrect calculation. Fix the initialization code to have it point to the end of the ring instead. One way to think about this, is that we are setting the value to be one prior to the first available descriptor. Doing so, corrects the delta calculation in all cases. The original fix only works if the first packet has exactly one descriptor. Otherwise, we will report 1 less than the correct value. As part of this fix, also update the MPASS assertions to match the real expectations. First, ensure that prev is not equal to cur, since this should never happen. Second, remove the assertion about prev==0 || delta != 0. It looks like that originated from when the em driver was converted to iflib. It seems like it was supposed to ensure that delta was non-zero. However, because we originally returned 0 delta for the first calculation, the "prev == 0" was tacked on. Instead, replace this with a check that delta is greater than zero, after the correction necessary when the ring pointers wrap around. This new solution should fix the same bug as r341156 did, but in a more robust way.

* ixl/iavf(4): Fix TSO offloads when TXCSUM is disabledEric Joyner2018-11-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From Jake: The iflib stack does not disable TSO automatically when TXCSUM is disabled, instead assuming that the driver will correctly handle TSOs even when CSUM_IP is not set. This results in iflib calling ixl_isc_txd_encap with packets which have CSUM_IP_TSO, but do not have CSUM_IP or CSUM_IP_TCP set. Because of this, ixl_tx_setup_offload will not setup the IPv4 checksum offloading. This results in bad TSO packets being sent if a user disables TXCSUM without disabling TSO. Fix this by updating the ixl_tx_setup_offload function to check both CSUM_IP and CSUM_IP_TSO when deciding whether to enable IPv4 checksums. Once this is corrected, another issue for TSO packets is revealed. The driver sets IFLIB_NEED_ZERO_CSUM in order to enable a work around that causes the ip->sum field to be zero'd. This is necessary for ixl hardware to correctly perform TSOs. However, if TXCSUM is disabled, then the work around is not enabled, as CSUM_IP will not be set when the iflib stack checks to see if it should clear the sum field. Fix this by adding IFLIB_TSO_INIT_IP to the iflib flags for the iavf and ixl interface files. It is uncertain if the hardware needs IFLIB_NEED_ZERO_CSUM for any other case besides TSO, so leave that flag assigned. It may be worth investigating to see if this work around flag could be disabled in a future change. Once both of these changes are made, the ixl driver should correctly offload TSO packets when TSO4 offload is enabled, regardless of whether TXCSUM is enabled or disabled.

| | | | | | | | | | | | | | | | | | | | | | | | | Finishes the conversion of the 40Gb Intel Ethernet drivers to iflib(9) for FreeBSD 12.0, and fixes numerous bugs in both ixl(4) and iavf(4). This commit also re-adds the VF driver to GENERIC since it now compiles and functions. The VF driver name was changed from ixlv(4) to iavf(4) because the VF driver is now intended to be used with future products, not just with Fortville/Fort Park VFs. A man page update that documents these drivers is forthcoming in a separate commit.

This patch includes fixes for ixv, ixl, ix, re, cxgbe, iflib, vtnet and ptnet drivers to cope with the change. - Generalize the nm_config() callback to accept a struct containing many parameters. - Introduce NKR_FAKERING to support buffers sharing (used for netmap pipes) - Improved API for external VALE modules. - Various bug fixes and improvements to the netmap memory allocator, including support for externally (userspace) allocated memory. - Refactoring of netmap pipes: now linked rings share the same netmap buffers, with a separate set of kring pointers (rhead, rcur, rtail). Buffer swapping does not need to happen anymore. - Large refactoring of the control API towards an extensible solution; the goal is to allow the addition of more commands and extension of existing ones (with new options) without the need of hacks or the risk of running out of configuration space. A new NIOCCTRL ioctl has been added to handle all the requests of the new control API, which cover all the functionalities so far supported. The netmap API bumps from 11 to 12 with this patch. Full backward compatibility is provided for the old control command (NIOCREGIF), by means of a new netmap_legacy module. Many parts of the old netmap.h header has now been moved to netmap_legacy.h (included by netmap.h). Approved by: hrs (mentor) Notes: svn path=/head/; revision=332423

* ixl(4)/ixlv(4): Stop leaking every busdma entry in receive pathEric Joyner2017-07-131-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | From Brett: In short, busdma maps for received packets were not being unloaded in the interrupt handler before the packets were passed up the network stack. The fix was to add a busdma sync and unload for the two receive maps. This bug is significant for certain busdma providers, for example IOMMUs, where not unloading the maps means that 1) the IOMMU mappings that allow the NIC to DMA the received packets into host memory stay open indefinitely, potentially violating a desired security policy, and 2) resources such as device address space addresses and host memory for bookkeeping are never freed. Without an IOMMU or bounce buffering enabled for the ixl device, I don't think adding these calls will have any significant performance impact. With the IOMMU enabled, I have noticed a performance impact on the receive side, which is expected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Description from Brett: "The busdma tags used to create mappings for the tx and rx rings did not have the device's tag as parents, meaning that they did not respect the device's busdma properties. The other tags used in the driver had their parents set appropriately. Also, the dma maps for each buffer in ixl_txeof() were being NULLed after being unloaded, which is an error because those maps are then reused without being recreated (I believe this also leaked resources since the maps were not destroyed). Simply removing the line that sets the maps to NULL gives the desired behavior. There does not seem to be a similar problem with ixl_rxeof(). Functions to free the tx and rx rings also NULL out the dma maps for each buffer, but this seems okay because the maps are destroyed and not reused in this case. With these fixes, my ixl card seems to be working with the IOMMU enabled."

To modify the "m_pkthdr.rsstype" field please use the existing "M_HASHTYPE_XXX" macros as defined in the "sys/mbuf.h" header file. This patch introduces new behaviour in the transmit direction. Previously network drivers checked if "M_FLOWID" was set in "m_flags" before using the "m_pkthdr.flowid" field. This check has now now been replaced by checking if "M_HASHTYPE_GET(m)" is different from "M_HASHTYPE_NONE". In the future more hashtypes will be added, for example hashtypes for hardware dedicated flows. "M_HASHTYPE_OPAQUE" indicates that the "m_pkthdr.flowid" value is valid and has no particular type. This change removes the need for an "if" statement in TCP transmit code checking for the presence of a valid flowid value. The "if" statement mentioned above is now a direct variable assignment which is then later checked by the respective network drivers like before. Additional notes: - The SCTP code changes will be committed as a separate patch. - Removal of the "M_FLOWID" flag will also be done separately. - The FreeBSD version has been bumped.

- It was decided to change the driver name to if_ixl for FreeBSD - This release adds the VF Driver to the tree, it can be built into the kernel or as the if_ixlv module - The VF driver is independent for the first time, this will be desireable when full SRIOV capability is added to the OS. - Thanks to my new coworker Eric Joyner for his superb work in both the core and vf driver code. Enjoy everyone! Submitted by: jack.vogel@intel.com and eric.joyner@intel.com MFC after: 3 days (hoping to make 10.1) Notes: svn path=/head/; revision=270346
