um: vector: Fix memory leak in vector_config

2023-02-01T21:11:27+00:00

If the return value of the uml_parse_vector_ifspec function is NULL, we should call kfree(params) to prevent memory leak. Fixes: 49da7e64f33e ("High Performance UML Vector Network Driver") Signed-off-by: Xiang Yang Acked-By: Anton Ivanov Signed-off-by: Richard Weinberger

um: move from strlcpy with unused retval to strscpy

2022-09-19T20:45:24+00:00

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

um: vector: switch to netif_napi_add_weight()

2022-05-08T10:33:56+00:00

UM's netdev driver uses a custom napi weight, switch to the new API for setting custom weight. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

um: Migrate vector drivers to NAPI

2022-03-11T09:45:21+00:00

Migrate UML vector drivers from a bespoke scheduling mechanism to NAPI. Signed-off-by: Anton Ivanov Signed-off-by: Richard Weinberger

ethtool: extend ringparam setting/getting API with rx_buf_len

2021-11-22T12:31:49+00:00

Add two new parameters kernel_ringparam and extack for .get_ringparam and .set_ringparam to extend more ring params through netlink. Signed-off-by: Hao Chen Signed-off-by: Guangbin Huang Signed-off-by: David S. Miller

um: vector: adjust to coalesce API changes

2021-08-27T14:05:53+00:00

The API changes were propagated to most drivers, but clearly arch/um/drivers/ was missed, perhaps due to looking only at the drivers/ folder. Fix that.

um: Remove unused including

2021-04-15T21:10:43+00:00

Fix the following versioncheck warning: ./arch/um/drivers/vector_kern.c: 11 linux/version.h not needed. Reported-by: Abaci Robot Signed-off-by: Yang Li Signed-off-by: Richard Weinberger

um: Support dynamic IRQ allocation

2020-12-13T21:22:08+00:00

It's cumbersome and error-prone to keep adding fixed IRQ numbers, and for proper device wakeup support for the virtio/vhost-user support we need to have different IRQs for each device. Even if in theory two IRQs (with and without wake) might be sufficient, it's much easier to reason about it when we have dynamic number assignment. It also makes it easier to add new devices that may dynamically exist or depending on the configuration, etc. Add support for this, up to 64 IRQs (the same limit as epoll FDs we have right now). Since it's not easy to port all the existing places to dynamic allocation (some data is statically initialized) keep the low numbers are reserved for the existing hard-coded IRQ numbers.

um: Convert tasklets to use new tasklet_setup() API

2020-12-13T21:20:51+00:00

In preparation for unconditionally passing the struct tasklet_struct pointer to all tasklet callbacks, switch to using the new tasklet_setup() and from_tasklet() to pass the tasklet pointer explicitly.

um: vector: Use GFP_ATOMIC under spin lock

2020-10-11T21:13:00+00:00

Use GFP_ATOMIC instead of GFP_KERNEL under spin lock to fix possible sleep-in-atomic-context bugs. Fixes: 9807019a62dc ("um: Loadable BPF "Firmware" for vector drivers") Signed-off-by: Tiezhu Yang Acked-By: Anton Ivanov Signed-off-by: Richard Weinberger
