In the Linux kernel, the following vulnerability has been resolved:
bpf: Add schedule points in batch ops
syzbot reported various soft lockups caused by bpf batch operations.
INFO: task kworker/1:1:27 blocked for more than 140 seconds. INFO: task hung in rcu_barrier
Nothing prevents batch ops to process huge amount of data, we need to add schedule points in them.
Note that maybewaitbpfprograms(map) calls from genericmapdeletebatch() can be factorized by moving the call after the loop.
This will be done later in -next tree once we get this fix merged, unless there is strong opinion doing this optimization sooner.
