net: txgbe: free isb resources at the right time
Published Jul 30, 2024
7.8
HIGHCVSS 3.1
EPSS 0.23%
Description
When using MSI/INTx interrupt, the shared interrupts are still being handled in the device remove routine, before free IRQs. So isb memory is still read after it is freed. Thus move wx_free_isb_resources() from txgbe_close() to txgbe_remove(). And fix the improper isb free action in txgbe_open() error handling path.
