2020-09-02net: gemini: Fix another missing clk_disable_unprepare() in probeDan Carpenter1-17/+17
We recently added some calls to clk_disable_unprepare() but we missed the last error path if register_netdev() fails. I made a couple cleanups so we avoid mistakes like this in the future. First I reversed the "if (!ret)" condition and pulled the code in one indent level. Also, the "port->netdev = NULL;" is not required because "port" isn't used again outside this function so I deleted that line.

2020-09-01ibmvnic: Harden device Command Response Queue handshakeThomas Falcon1-1/+18
In some cases, the device or firmware may be busy when the driver attempts to perform the CRQ initialization handshake. If the partner is busy, the hypervisor will return the H_CLOSED return code. The aim of this patch is that, if the device is not ready, to query the device a number of times, with a small wait time in between queries. If all initialization requests fail, the driver will remain in a dormant state, awaiting a signal from the device that it is ready for operation.

Daniel Borkmann says: ==================== pull-request: bpf-next 2020-09-01 The following pull-request contains BPF updates for your *net-next* tree. There are two small conflicts when pulling, resolve as follows: 1) Merge conflict in tools/lib/bpf/libbpf.c between 88a82120282b ("libbpf: Factor out common ELF operations and improve logging") in bpf-next and 1e891e513e16 ("libbpf: Fix map index used in error message") in net-next. Resolve by taking the hunk in bpf-next: [...] scn = elf_sec_by_idx(obj, obj->efile.btf_maps_shndx); data = elf_sec_data(obj, scn); if (!scn || !data) { pr_warn("elf: failed to get %s map definitions for %s\n", MAPS_ELF_SEC, obj->path); return -EINVAL; } [...] 2) Merge conflict in drivers/net/ethernet/mellanox/mlx5/core/en/xsk/rx.c between 9647c57b11e5 ("xsk: i40e: ice: ixgbe: mlx5: Test for dma_need_sync earlier for better performance") in bpf-next and e20f0dbf204f ("net/mlx5e: RX, Add a prefetch command for small L1_CACHE_BYTES") in net-next. Resolve the two locations by retaining net_prefetch() and taking xsk_buff_dma_sync_for_cpu() from bpf-next.

performance Test for dma_need_sync earlier to increase performance. xsk_buff_dma_sync_for_cpu() takes an xdp_buff as parameter and from that the xsk_buff_pool reference is dug out. Perf shows that this dereference causes a lot of cache misses. But as the buffer pool is now sent down to the driver at zero-copy initialization time, we might as well use this pointer directly, instead of going via the xsk_buff and we can do so already in xsk_buff_dma_sync_for_cpu() instead of in xp_dma_sync_for_cpu. This gets rid of these cache misses. Throughput increases with 3% for the xdpsock l2fwd sample application on my machine.

Rename the AF_XDP zero-copy driver interface functions to better reflect what they do after the replacement of umems with buffer pools in the previous commit. Mostly it is about replacing the umem name from the function names with xsk_buff and also have them take the a buffer pool pointer instead of a umem. The various ring functions have also been renamed in the process so that they have the same naming convention as the internal functions in xsk_queue.h.

This in preparation for extending the functionality of the zero-copy mode so that umems can be shared between queues on the same netdev and also between netdevs. In this commit, only an umem reference has been added to the buffer pool struct. But later commits will add other entities to it. These are going to be entities that are different between different queue ids and netdevs even though the umem is shared between them.

2020-08-28ionic: change the descriptor ring length without full resetShannon Nelson3-14/+185
The original way of changing ring length was to completely tear down the lif's queue structure and then rebuild it, while running the risk of allocations that might fail in the middle and leave us with a broken driver. Instead, we can set up all the new queue and descriptor allocations first, then swap them out and delete the old allocations. If the new allocations fail, we report the error, stay with the old setup and continue running. This gives us a safer path, and a smaller window of time where we're not processing traffic.

2020-08-28ionic: change mtu without full queue rebuildShannon Nelson1-8/+49
We really don't need to tear down and rebuild the whole queue structure when changing the MTU; we can simply stop the queues, clean and refill, then restart the queues. Signed-off-by: Shannon Nelson <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2020-08-28ionic: use index not pointer for queue trackingShannon Nelson7-88/+129
Use index counters rather than pointers for tracking head and tail in the queues to save a little memory and to perhaps slightly faster queue processing. Signed-off-by: Shannon Nelson <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2020-08-28ionic: reduce contiguous memory allocation requirementShannon Nelson3-54/+81
Split out the queue descriptor blocks into separate dma allocations to make for smaller blocks. Co-developed-by: Neel Patel <[email protected]> Signed-off-by: Shannon Nelson <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2020-08-28ionic: clean up unnecessary non-static functionsShannon Nelson2-4/+2
ionic_open() and ionic_stop() are not referenced outside of their defining file, so make them static. Signed-off-by: Shannon Nelson <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2020-08-28ionic: rework and simplify handling of the queue stats blockShannon Nelson5-149/+92
Use a block of stats structs attached to the lif instead of little ones attached to each qcq. This simplifies our memory management and gets rid of a lot of unnecessary indirection. Signed-off-by: Shannon Nelson <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2020-08-28ionic: remove lif list conceptShannon Nelson6-127/+62
As we aren't yet supporting multiple lifs, we can remove complexity by removing the list concept and related code, to be re-engineered later when actually needed. Signed-off-by: Shannon Nelson <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2020-08-28ionic: use kcalloc for new arraysShannon Nelson1-4/+4
Use kcalloc for allocating arrays of structures. Following along after commit e71642009cbdA ("ionic_lif: Use devm_kcalloc() in ionic_qcq_alloc()") there are a couple more array allocations that can be converted to using devm_kcalloc().

2020-08-28ionic: set MTU floor at ETH_MIN_MTUShannon Nelson1-1/+2
The NIC might tell us its minimum MTU, but let's be sure not to use something smaller than ETH_MIN_MTU. Signed-off-by: Shannon Nelson <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2020-08-27net: ethernet: ti: cpsw_new: fix error handling in cpsw_ndo_vlan_rx_kill_vid()Murali Karicheri1-6/+21
This patch fixes a bunch of issues in cpsw_ndo_vlan_rx_kill_vid() - pm_runtime_get_sync() returns non zero value. This results in non zero value return to caller which will be interpreted as error. So overwrite ret with zero. - If VID matches with port VLAN VID, then set error code. - Currently when VLAN interface is deleted, all of the VLAN mc addresses are removed from ALE table, however the return values from ale function calls are not checked. These functions can return error code -ENOENT. But that shouldn't happen in a normal case. So add error print to catch the situations so that these can be investigated and addressed. return zero in these cases as these are not real error case, but only serve to catch ALE table update related issues and help address the same in the driver.

2020-08-27net: xgene: Move shared header file into include/linuxAndrew Lunn1-1/+1
This header file is currently included into the ethernet driver via a relative path into the PHY subsystem. This is bad practice, and causes issues for the upcoming move of the MDIO driver. Move the header file into include/linux to clean this up. v2: Move header to include/linux/mdio Reviewed-by: Florian Fainelli <[email protected]> Signed-off-by: Andrew Lunn <[email protected]> Signed-off-by: David S.

Move the header file into a subdirectory include/linux/pcs Start a naming convention of all PCS files use the prefix pcs-, and rename the XPCS files to fit. v2: Add include/linux/pcs v4: Fix include path in stmmac.
