2021-06-28bnxt_en: Add PTP clock APIs, ioctls, and ethtool methodsMichael Chan6-1/+382
Add the clock APIs to set/get/adjust the hw clock, and the related ioctls and ethtool methods. v2: Propagate error code from ptp_clock_register(). Add spinlock to serialize access to the timecounter. The timecounter is accessed in process context and the RX datapath. Read the PHC using direct registers.

2021-06-25net: bcmgenet: Add mdio-bcm-unimac soft dependencyJian-Hong Pan1-0/+1
The Broadcom UniMAC MDIO bus from mdio-bcm-unimac module comes too late. So, GENET cannot find the ethernet PHY on UniMAC MDIO bus. This leads GENET fail to attach the PHY as following log: bcmgenet fd580000.ethernet: GENET 5.0 EPHY: 0x0000 ... could not attach to PHY bcmgenet fd580000.ethernet eth0: failed to connect to PHY uart-pl011 fe201000.serial: no DMA platform data libphy: bcmgenet MII bus: probed ... unimac-mdio unimac-mdio.-19: Broadcom UniMAC MDIO bus It is not just coming too late, there is also no way for the module loader to figure out the dependency between GENET and its MDIO bus driver unless we provide this MODULE_SOFTDEP hint. This patch adds the soft dependency to load mdio-bcm-unimac module before genet module to fix this issue.

2021-06-24bnxt: Remove rcu_read_lock() around XDP program invocationToke Høiland-Jørgensen1-2/+0
The bnxt driver has rcu_read_lock()/rcu_read_unlock() pairs around XDP program invocations. However, the actual lifetime of the objects referred by the XDP program invocation is longer, all the way through to the call to xdp_do_flush(), making the scope of the rcu_read_lock() too small. This turns out to be harmless because it all happens in a single NAPI poll cycle (and thus under local_bh_disable()), but it makes the rcu_read_lock() misleading. Rather than extend the scope of the rcu_read_lock(), just get rid of it entirely. With the addition of RCU annotations to the XDP_REDIRECT map types that take bh execution into account, lockdep even understands this to be safe, so there's really no reason to keep it around.

Resetting software indexes in bcm4908_dma_alloc_buf_descs() is not enough as it's called during device probe only. Driver resets DMA on every .ndo_open callback and it's required to reset indexes then. This fixes inconsistent rings state and stalled traffic after interface down & up sequence.

2021-05-12bnxt_en: Fix and improve .ndo_features_check().Michael Chan1-19/+107
Jakub Kicinski pointed out that we need to handle ipv6 extension headers and to explicitly check for supported tunnel types in .ndo_features_check(). For ipv6 extension headers, the hardware supports up to 2 ext. headers and each must be <= 64 bytes. For tunneled packets, the supported packets are UDP with supported VXLAN and Geneve ports, GRE, and IPIP. v3: More improvements based on Alexander Duyck's valuable feedback - Remove the jump lable in bnxt_features_check() and restructure it so that the TCP/UDP is check is consolidated in bnxt_exthdr_check(). v2: Add missing step to check inner ipv6 header for UDP and GRE tunnels. Check TCP/UDP next header after skipping ipv6 ext headers for non-tunneled packets and for inner ipv6.

2021-04-26bnxt_en: allow promiscuous mode for trusted VFsEdwin Peer3-7/+11
Firmware previously only allowed promiscuous mode for VFs associated with a default VLAN. It is now possible to enable promiscuous mode for a VF having no VLAN configured provided that it is trusted. In such cases the VF will see all packets received by the PF, irrespective of destination MAC or VLAN. Note, it is necessary to query firmware at the time of bnxt_promisc_ok() instead of in bnxt_hwrm_func_qcfg() because the trusted status might be altered by the PF after the VF has been configured. This check must now also be deferred because the firmware call sleeps.

2021-04-26bnxt_en: Fix RX consumer index logic in the error path.Michael Chan1-2/+4
In bnxt_rx_pkt(), the RX buffers are expected to complete in order. If the RX consumer index indicates an out of order buffer completion, it means we are hitting a hardware bug and the driver will abort all remaining RX packets and reset the RX ring. The RX consumer index that we pass to bnxt_discard_rx() is not correct. We should be passing the current index (tmp_raw_cons) instead of the old index (raw_cons). This bug can cause us to be at the wrong index when trying to abort the next RX packet. It can crash like this: #0 [ffff9bbcdf5c39a8] machine_kexec at ffffffff9b05e007 #1 [ffff9bbcdf5c3a00] __crash_kexec at ffffffff9b111232 #2 [ffff9bbcdf5c3ad0] panic at ffffffff9b07d61e #3 [ffff9bbcdf5c3b50] oops_end at ffffffff9b030978 #4 [ffff9bbcdf5c3b78] no_context at ffffffff9b06aaf0 #5 [ffff9bbcdf5c3bd8] __bad_area_nosemaphore at ffffffff9b06ae2e #6 [ffff9bbcdf5c3c28] bad_area_nosemaphore at ffffffff9b06af24 #7 [ffff9bbcdf5c3c38] __do_page_fault at ffffffff9b06b67e #8 [ffff9bbcdf5c3cb0] do_page_fault at ffffffff9b06bb12 #9 [ffff9bbcdf5c3ce0] page_fault at ffffffff9bc015c5 [exception RIP: bnxt_rx_pkt+237] RIP: ffffffffc0259cdd RSP: ffff9bbcdf5c3d98 RFLAGS: 00010213 RAX: 000000005dd8097f RBX: ffff9ba4cb11b7e0 RCX: ffffa923cf6e9000 RDX: 0000000000000fff RSI: 0000000000000627 RDI: 0000000000001000 RBP: ffff9bbcdf5c3e60 R8: 0000000000420003 R9: 000000000000020d R10: ffffa923cf6ec138 R11: ffff9bbcdf5c3e83 R12: ffff9ba4d6f928c0 R13: ffff9ba4cac28080 R14: ffff9ba4cb11b7f0 R15: ffff9ba4d5a30000 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 Fixes: a1b0e4e684e9 ("bnxt_en: Improve RX consumer index validity check.")

The problem is that bnxt_show_temp() returns long but "rc" is an int and "len" is a u32. With ternary operations the type promotion is quite tricky.

2021-04-14of: net: pass the dst buffer to of_get_mac_address()Michael Walle4-22/+13
of_get_mac_address() returns a "const void*" pointer to a MAC address. Lately, support to fetch the MAC address by an NVMEM provider was added. But this will only work with platform devices. It will not work with PCI devices (e.g. of an integrated root complex) and esp. not with DSA ports. There is an of_* variant of the nvmem binding which works without devices. The returned data of a nvmem_cell_read() has to be freed after use. On the other hand the return of_get_mac_address() points to some static data without a lifetime. The trick for now, was to allocate a device resource managed buffer which is then returned. This will only work if we have an actual device. Change it, so that the caller of of_get_mac_address() has to supply a buffer where the MAC address is written to. Unfortunately, this will touch all drivers which use the of_get_mac_address(). Usually the code looks like: const char *addr; addr = of_get_mac_address(np); if (!IS_ERR(addr)) ether_addr_copy(ndev->dev_addr, addr); This can then be simply rewritten as: of_get_mac_address(np, ndev->dev_addr); Sometimes is_valid_ether_addr() is used to test the MAC address. of_get_mac_address() already makes sure, it just returns a valid MAC address. Thus we can just test its return code. But we have to be careful if there are still other sources for the MAC address before the of_get_mac_address(). In this case we have to keep the is_valid_ether_addr() call. The following coccinelle patch was used to convert common cases to the new style. Afterwards, I've manually gone over the drivers and fixed the return code variable: either used a new one or if one was already available use that. Mansour Moufid, thanks for that coccinelle patch! <spml> @a@ identifier x; expression y, z; @@ - x = of_get_mac_address(y); + x = of_get_mac_address(y, z); <... - ether_addr_copy(z, x); ...> @@ identifier a.x; @@ - if (<+... x ...+>) {} @@ identifier a.x; @@ if (<+... x ...+>) { ... } - else {} @@ identifier a.x; expression e; @@ - if (<+... x ...+>@e) - {} - else + if (!(e)) {...} @@ expression x, y, z; @@ - x = of_get_mac_address(y, z); + of_get_mac_address(y, z); ... when != x </spml> All drivers, except drivers/net/ethernet/aeroflex/greth.c, were compile-time tested.
