2023-12-04net: stmmac: xgmac: EST interrupts handlingRohan G Thomas2-0/+117
Enabled the following EST related interrupts: 1) Constant Gate Control Error (CGCE) 2) Head-of-Line Blocking due to Scheduling (HLBS) 3) Head-of-Line Blocking due to Frame Size (HLBF) 4) Base Time Register error (BTRE) 5) Switch to S/W owned list Complete (SWLC) Also, add EST errors into the ethtool statistic. The commit e49aa315cb01 ("net: stmmac: EST interrupts handling and error reporting") and commit 9f298959191b ("net: stmmac: Add EST errors into ethtool statistic") add EST interrupts handling and error reporting support to DWMAC4 core. This patch enables the same support for XGMAC.

The current code determines the last backing store valid type during bnxt_hwrm_func_backing_store_qcaps_v2(). In effect, the last type is determined based on what firmware advertises. The more correct way is to determine it based on what the driver is configuring. The driver may not configure all the backing store types advertised by firmware.

When breaking out the Gen4 gPTP support to its own module the dependency on the PTP_1588_CLOCK framework was left as optional and only stated for the driver using the module. This leads to issues when doing COMPILE_TEST of RENESAS_GEN4_PTP separately and PTP_1588_CLOCK is built as a module and the other as a built-in. Add an explicit depend on PTP_1588_CLOCK. While at it remove the optional support for PTP_1588_CLOCK from RENESAS_ETHER_SWITCH as the driver unconditionally calls the Gen4 gPTP module and thus also requires the PTP_1588_CLOCK framework.

Deassert the phy_device's reset as part of registering 3. Deassert the phy_device's reset as part of phy_probe 4.

The main changes are: 1) Add initial TX metadata implementation for AF_XDP with support in mlx5 and stmmac drivers. Two types of offloads are supported right now, that is, TX timestamp and TX checksum offload, from Stanislav Fomichev with stmmac implementation from Song Yoong Siang. 2) Change BPF verifier logic to validate global subprograms lazily instead of unconditionally before the main program, so they can be guarded using BPF CO-RE techniques, from Andrii Nakryiko. 3) Add BPF link_info support for uprobe multi link along with bpftool integration for the latter, from Jiri Olsa. 4) Use pkg-config in BPF selftests to determine ld flags which is in particular needed for linking statically, from Akihiko Odaki. 5) Fix a few BPF selftest failures to adapt to the upcoming LLVM18, from Yonghong Song. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (30 commits) bpf/tests: Remove duplicate JSGT tests selftests/bpf: Add TX side to xdp_hw_metadata selftests/bpf: Convert xdp_hw_metadata to XDP_USE_NEED_WAKEUP selftests/bpf: Add TX side to xdp_metadata selftests/bpf: Add csum helpers selftests/xsk: Support tx_metadata_len xsk: Add option to calculate TX checksum in SW xsk: Validate xsk_tx_metadata flags xsk: Document tx_metadata_len layout net: stmmac: Add Tx HWTS support to XDP ZC net/mlx5e: Implement AF_XDP TX timestamp and checksum offload tools: ynl: Print xsk-features from the sample xsk: Add TX timestamp and TX checksum offload support xsk: Support tx_metadata_len selftests/bpf: Use pkg-config for libelf selftests/bpf: Override PKG_CONFIG for static builds selftests/bpf: Choose pkg-config for the target bpftool: Add support to display uprobe_multi links selftests/bpf: Add link_info test for uprobe_multi link selftests/bpf: Use bpf_link__destroy in fill_link_info tests ... ==================== Conflicts: Documentation/netlink/specs/netdev.yaml: 839ff60df3ab ("net: page_pool: add nlspec for basic access to page pools") 48eb03dd2630 ("xsk: Add TX timestamp and TX checksum offload support") https://lore.kernel.org/all/20231201094705.1ee3cab8@canb.auug.org.au/ While at it also regen, tree is dirty after: 48eb03dd2630 ("xsk: Add TX timestamp and TX checksum offload support") looks like code wasn't re-rendered after "render-max" was removed.

2023-11-30net: ethernet: ezchip: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-11-30net: ravb: Keep reverse order of operations in ravb_remove()Claudiu Beznea1-9/+13
On RZ/G3S SMARC Carrier II board having RGMII connections b/w Ethernet MACs and PHYs it has been discovered that doing unbind/bind for ravb driver in a loop leads to wrong speed and duplex for Ethernet links and broken connectivity (the connectivity cannot be restored even with bringing interface down/up). Before doing unbind/bind the Ethernet interfaces were configured though systemd. The sh instructions used to do unbind/bind were: $ cd /sys/bus/platform/drivers/ravb/ $ while :; do echo 11c30000.ethernet > unbind ; \ echo 11c30000.ethernet > bind; done It has been discovered that there is a race b/w IOCTLs initialized by systemd at the response of success binding and the "ravb_write(ndev, CCC_OPC_RESET, CCC)" call in ravb_remove() as follows: 1/ as a result of bind success the user space open/configures the interfaces tough an IOCTL; the following stack trace has been identified on RZ/G3S: Call trace: dump_backtrace+0x9c/0x100 show_stack+0x20/0x38 dump_stack_lvl+0x48/0x60 dump_stack+0x18/0x28 ravb_open+0x70/0xa58 __dev_open+0xf4/0x1e8 __dev_change_flags+0x198/0x218 dev_change_flags+0x2c/0x80 devinet_ioctl+0x640/0x708 inet_ioctl+0x1e4/0x200 sock_do_ioctl+0x50/0x108 sock_ioctl+0x240/0x358 __arm64_sys_ioctl+0xb0/0x100 invoke_syscall+0x50/0x128 el0_svc_common.constprop.0+0xc8/0xf0 do_el0_svc+0x24/0x38 el0_svc+0x34/0xb8 el0t_64_sync_handler+0xc0/0xc8 el0t_64_sync+0x190/0x198 2/ this call may execute concurrently with ravb_remove() as the unbind/bind operation was executed in a loop 3/ if the operation mode is changed to RESET (through ravb_write(ndev, CCC_OPC_RESET, CCC) call in ravb_remove()) while the above ravb_open() is in progress it may lead to MAC (or PHY, or MAC-PHY connection, the right point hasn't been identified at the moment) to be broken, thus the Ethernet connectivity fails to restore. The simple fix for this is to move ravb_write(ndev, CCC_OPC_RESET, CCC)) after unregister_netdev() to avoid resetting the controller while the netdev interface is still registered. To avoid future issues in ravb_remove(), the patch follows the proper order of operations in ravb_remove(): reverse order compared with ravb_probe(). This avoids described races as the IOCTLs as well as unregister_netdev() (called now at the beginning of ravb_remove()) calls rtnl_lock() before continuing and IOCTLs check (though devinet_ioctl()) if device is still registered just after taking the lock: int devinet_ioctl(struct net *net, unsigned int cmd, struct ifreq *ifr) { // ... rtnl_lock(); ret = -ENODEV; dev = __dev_get_by_name(net, ifr->ifr_name); if (!dev) goto done; // ... done: rtnl_unlock(); out: return ret; } Fixes: c156633f1353 ("Renesas Ethernet AVB driver proper") Reviewed-by: Sergey Shtylyov <s.shtylyov@omp.ru> Signed-off-by: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

registers Hardware manual of RZ/G3S (and RZ/G2L) specifies the following on the description of CXR35 register (chapter "PHY interface select register (CXR35)"): "After release reset, make write-access to this register before making write-access to other registers (except MDIOMOD). Even if not need to change the value of this register, make write-access to this register at least one time. Because RGMII/MII MODE is recognized by accessing this register". The setup procedure for EMAC module (chapter "Setup procedure" of RZ/G3S, RZ/G2L manuals) specifies the E-MAC.CXR35 register is the first EMAC register that is to be configured. Note [A] from chapter "PHY interface select register (CXR35)" specifies the following: [A] The case which CXR35 SEL_XMII is used for the selection of RGMII/MII in APB Clock 100 MHz. (1) To use RGMII interface, Set ‘H’03E8_0000’ to this register. (2) To use MII interface, Set ‘H’03E8_0002’ to this register. Take into account these indication.
