2021-07-15qed: fix possible unpaired spin_{un}lock_bh in _qed_mcp_cmd_and_union()Jia He
Liajian reported a bug_on hit on a ThunderX2 arm64 server with FastLinQ QL41000 ethernet controller: BUG: scheduling while atomic: kworker/0:4/531/0x00000200 [qed_probe:488()]hw prepare failed kernel BUG at mm/vmalloc.c:2355! Internal error: Oops - BUG: 0 [#1] SMP CPU: 0 PID: 531 Comm: kworker/0:4 Tainted: G W 5.4.0-77-generic #86-Ubuntu pstate: 00400009 (nzcv daif +PAN -UAO) Call trace: vunmap+0x4c/0x50 iounmap+0x48/0x58 qed_free_pci+0x60/0x80 [qed] qed_probe+0x35c/0x688 [qed] __qede_probe+0x88/0x5c8 [qede] qede_probe+0x60/0xe0 [qede] local_pci_probe+0x48/0xa0 work_for_cpu_fn+0x24/0x38 process_one_work+0x1d0/0x468 worker_thread+0x238/0x4e0 kthread+0xf0/0x118 ret_from_fork+0x10/0x18 In this case, qed_hw_prepare() returns error due to hw/fw error, but in theory work queue should be in process context instead of interrupt. The root cause might be the unpaired spin_{un}lock_bh() in _qed_mcp_cmd_and_union(), which causes botton half is disabled incorrectly.

2021-06-24qede: Remove rcu_read_lock() around XDP program invocationToke Høiland-Jørgensen
The qede 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.

2021-06-17net: qed: Fix memcpy() overflow of qed_dcbx_params()Kees Cook
The source (&dcbx_info->operational.params) and dest (&p_hwfn->p_dcbx_info->set.config.params) are both struct qed_dcbx_params (560 bytes), not struct qed_dcbx_admin_params (564 bytes), which is used as the memcpy() size. However it seems that struct qed_dcbx_operational_params (dcbx_info->operational)'s layout matches struct qed_dcbx_admin_params (p_hwfn->p_dcbx_info->set.config)'s 4 byte difference (3 padding, 1 byte for "valid"). On the assumption that the size is wrong (rather than the source structure type), adjust the memcpy() size argument to be 4 bytes smaller and add a BUILD_BUG_ON() to validate any changes to the structure sizes.

2021-05-20net/qla3xxx: fix schedule while atomic in ql_sem_spinlockZheyu Ma
When calling the 'ql_sem_spinlock', the driver has already acquired the spin lock, so the driver should not call 'ssleep' in atomic context. This bug can be fixed by using 'mdelay' instead of 'ssleep'.

The function qlcnic_dl_lb_test() currently calls netdev_alloc_skb() without checking afterwards that the allocation succeeded.

Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change.

2021-03-18bpf, devmap: Move drop error path to devmap for XDP_REDIRECTLorenzo Bianconi
We want to change the current ndo_xdp_xmit drop semantics because it will allow us to implement better queue overflow handling. This is working towards the larger goal of a XDP TX queue-hook. Move XDP_REDIRECT error path handling from each XDP ethernet driver to devmap code. According to the new APIs, the driver running the ndo_xdp_xmit pointer, will break tx loop whenever the hw reports a tx error and it will just return to devmap caller the number of successfully transmitted frames. It will be devmap responsibility to free dropped frames. Move each XDP ndo_xdp_xmit capable driver to the new APIs: - veth - virtio-net - mvneta - mvpp2 - socionext - amazon ena - bnxt - freescale (dpaa2, dpaa) - xen-frontend - qede - ice - igb - ixgbe - i40e - mlx5 - ti (cpsw, cpsw-new) - tun - sfc Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Reviewed-by: Ioana Ciornei <ioana.ciornei@nxp.com> Reviewed-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Reviewed-by: Camelia Groza <camelia.groza@nxp.com> Acked-by: Edward Cree <ecree.xilinx@gmail.com> Acked-by: Jesper Dangaard Brouer <brouer@redhat.com> Acked-by: Shay Agroskin <shayagr@amazon.com> Link: https://lore.kernel.org/bpf/ed670de24f951cfd77590decf0229a0ad7fd12f6.1615201152.git.lorenzo@kernel.org

2021-01-09netxen_nic: fix MSI/MSI-x interruptsManish Chopra
For all PCI functions on the netxen_nic adapter, interrupt mode (INTx or MSI) configuration is dependent on what has been configured by the PCI function zero in the shared interrupt register, as these adapters do not support mixed mode interrupts among the functions of a given adapter. Logic for setting MSI/MSI-x interrupt mode in the shared interrupt register based on PCI function id zero check is not appropriate for all family of netxen adapters, as for some of the netxen family adapters PCI function zero is not really meant to be probed/loaded in the host but rather just act as a management function on the device, which caused all the other PCI functions on the adapter to always use legacy interrupt (INTx) mode instead of choosing MSI/MSI-x interrupt mode. This patch replaces that check with port number so that for all type of adapters driver attempts for MSI/MSI-x interrupt modes.
