[PATCH 6.1 0566/1146] Bluetooth: RFCOMM: dont call kfree_skb() under spin_lock_irqsave()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Yang Yingliang <yangyingliang@xxxxxxxxxx>

[ Upstream commit 0ba18967d4544955b2eff2fbc4f2a8750c4df90a ]

It is not allowed to call kfree_skb() from hardware interrupt
context or with interrupts being disabled. So replace kfree_skb()
with dev_kfree_skb_irq() under spin_lock_irqsave().

Fixes: 81be03e026dc ("Bluetooth: RFCOMM: Replace use of memcpy_from_msg with bt_skb_sendmmsg")
