Jia-Ju Bai 16fe10cf92 net: cadence: Fix a sleep-in-atomic-context bug in macb_halt_tx() ... The kernel module may sleep with holding a spinlock. The function call paths (from bottom to top) in Linux-4.16 are: [FUNC] usleep_range drivers/net/ethernet/cadence/macb_main.c, 648: usleep_range in macb_halt_tx drivers/net/ethernet/cadence/macb_main.c, 730: macb_halt_tx in macb_tx_error_task drivers/net/ethernet/cadence/macb_main.c, 721: _raw_spin_lock_irqsave in macb_tx_error_task To fix this bug, usleep_range() is replaced with udelay(). This bug is found by my static analysis tool DSAC. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>		2018-09-02 16:05:25 -07:00
