amd-xgbe: Use __napi_schedule() in BH context

2020-04-21T07:06:09Z

[ Upstream commit d518691cbd3be3dae218e05cca3f3fc9b2f1aa77 ] The driver uses __napi_schedule_irqoff() which is fine as long as it is invoked with disabled interrupts by everybody. Since the commit mentioned below the driver may invoke xgbe_isr_task() in tasklet/softirq context. This may lead to list corruption if another driver uses __napi_schedule_irqoff() in IRQ context. Use __napi_schedule() which safe to use from IRQ and softirq context.

treewide: Use sizeof_field() macro

2019-12-09T18:36:44Z

Replace all the occurrences of FIELD_SIZEOF() with sizeof_field() except at places where these are defined. Later patches will remove the unused definition of FIELD_SIZEOF(). This patch is generated using following script: EXCLUDE_FILES="include/linux/stddef.h|include/linux/kernel.h" git grep -l -e "\bFIELD_SIZEOF\b" | while read file; do if [[ "$file" =~ $EXCLUDE_FILES ]]; then continue fi sed -i -e 's/\bFIELD_SIZEOF\b/sizeof_field/g' $file; done Signed-off-by: Pankaj Bharadiya Link: https://lore.kernel.org/r/20190924105839.110713-3-pankaj.laxminarayan.bharadiya@intel.com Co-developed-by: Kees Cook Signed-off-by: Kees Cook Acked-by: David Miller # for net

In xgbe_mod_init(), we should do cleanup if some error occurs Reported-by: Hulk Robot Fixes: efbaa828330a ("amd-xgbe: Add support to handle device renaming") Fixes: 47f164deab22 ("amd-xgbe: Add PCI device support") Signed-off-by: YueHaibing Signed-off-by: David S. Miller

ethernet: Delete unnecessary checks before the macro call “dev_kfree_skb”

2019-08-22T23:22:04Z

The dev_kfree_skb() function performs also input parameter validation. Thus the test around the shown calls is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: David S. Miller

xgbe: no need to check return value of debugfs_create functions

2019-08-10T22:25:47Z

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. This cleans up a lot of unneeded code and logic around the debugfs files, making all of this much simpler and easier to understand. Cc: Tom Lendacky Cc: "David S.

net: Remove dev_err() usage after platform_get_irq()

2019-07-30T21:37:35Z

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( $ ret < 0 \| ret <= 0 $ ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // While we're here, remove braces on if statements that only have one statement (manually).
