Details

In the Linux kernel, the following vulnerability has been resolved:

bpf: bpflocalstorage: Always use bpfmemalloc in PREEMPT_RT

In PREEMPTRT, kmalloc(GFPATOMIC) is still not safe in non preemptible context. bpfmemalloc must be used in PREEMPTRT. This patch is to enforce bpfmemalloc in the bpflocalstorage when CONFIGPREEMPT_RT is enabled.

[ 35.118559] BUG: sleeping function called from invalid context at kernel/locking/spinlockrt.c:48 [ 35.118566] inatomic(): 1, irqsdisabled(): 0, nonblock: 0, pid: 1832, name: testprogs [ 35.118569] preemptcount: 1, expected: 0 [ 35.118571] RCU nest depth: 1, expected: 1 [ 35.118577] INFO: lockdep is turned off. ...

There is no need to adjust the gfpflags passing to the bpfmemcacheallocflags() which only honors the GFPKERNEL. The verifier has ensured GFP_KERNEL is passed only in sleepable context.

It has been an old issue since the first introduction of the bpflocalstorage ~5 years ago, so this patch targets the bpf-next.

bpfmemalloc is needed to solve it, so the Fixes tag is set to the commit when bpfmemalloc was first used in the bpflocalstorage.
