Analyze and fix the following issue in the Linux kernel code: PHYLIB: fix an interrupt loop potential when halting
Problem Details: Ensure the PHY_HALTED state is not entered with the IRQ asserted as it could lead to an interrupt loop. There is a small window in phy_stop(), where the state of the PHY machine indicates it has been halted, but its interrupt output might still be unmasked. If an interrupt goes active right at this m...

Analyze and fix the following issue in the Linux kernel code: cxgb3 - Set the CQ_ERR bit in CQ contexts.
Problem Details: The cxgb3 driver is incorrectly configuring the HW CQ context for CQ's that use overflow-avoidance. Namely the RDMA control CQ. This results in a bad DMA from the device to bus address 0. The solution is to set the CQ_ERR bit in the context for these types of CQs. Signed-off-by: Divy Le Ray <divy@c...

Analyze and fix the following issue in the Linux kernel code: [MAC80211]: fix race conditions with keys
Problem Details: During receive processing, we select the key long before using it and because there's no locking it is possible that we kfree() the key after having selected it but before using it for crypto operations. Obviously, this is bad. Secondly, during transmit processing, there are two possible races: We hav...
