Re: r8169 regression: UDP packets dropped intermittantly

Resend to netdev. LKML CCed in case anyone in the wider kernel community can suggest a way forward. Please CC responses if replying only to LKML. It seems that this 4+ year old regression in the r8169 driver (documented in this thread on netdev beginning on 9 March 2013) will never be fixed,

[PATCH] net: qcom/emac: Change the order of mac up and sgmii open

This patch fixes the order of mac_up and sgmii_open for the reasons noted below: - If open takes more time(if the SGMII block is not responding or if we want to do some delay based task) in this situation we will hit NETDEV watchdog - The main reason : We should signal to upper layers that we

[PATCH] KVM/Eventfd: Avoid crash when assign and deassign same eventfd in parallel.

Syzroot reports crash in kvm_irqfd_assign() is caused by use-after-free. Because kvm_irqfd_assign() and kvm_irqfd_deassign() can't run in parallel for same eventfd. When assign path hasn't been finished after irqfd has been added to kvm->irqfds.items list, another thead may deassign the eventfd
