  "message": "[PPPOL2TP]: Make locking calls softirq-safe\n\nFix locking issues in the pppol2tp driver which can cause a kernel\ncrash on SMP boxes. There were two problems:-\n\n1. The driver was violating read_lock() and write_lock() scheduling\n   rules because it wasn\u0027t using softirq-safe locks in softirq\n   contexts. So we now consistently use the _bh variants of the lock\n   functions.\n\n2. The driver was calling sk_dst_get() in pppol2tp_xmit() which was\n   taking sk_dst_lock in softirq context. We now call __sk_dst_get().\n\nSigned-off-by: James Chapman \u003cjchapman@katalix.com\u003e\nSigned-off-by: David S. Miller \u003cdavem@davemloft.net\u003e\n",
