Description
In the Linux kernel, the following vulnerability has been resolved:
bpf: Drop task_to_inode and inet_conn_established from lsm sleepable hooks
bpf_lsm_task_to_inode() is called under rcu_read_lock() and
bpf_lsm_inet_conn_established() is called from softirq context, so
neither hook can be used by sleepable LSM programs.
