Severity

Summary

In the Linux kernel, the following vulnerability has been resolved: sunrpc: route to a populated pool in svc_pool_for_cpu() svc_set_num_threads() spreads the requested threads evenly across the service's pools (base = nrservs / sv_nrpools). When a service runs fewer threads than it has pools -- e.g. an nfsd configured with fewer threads than the host has NUMA nodes while running in "pernode" or "percpu" mode -- the trailing pools are left with no threads at all. svc_xprt_enqueue() selects a pool from the CPU servicing the transport, queues the transport on that pool's sp_xprts, and only wakes a thread from the same pool. Each thread services exclusively its own pool, so a transport that lands on a threadless pool is enqueued on sp_xprts and never picked up: the connection hangs indefinitely. Have svc_pool_for_cpu() skip pools that currently have no threads, falling back to the next populated pool. This trades NUMA locality for a guarantee that the work is actually serviced. sp_nrthreads is only updated under the service mutex; the lockless read here is a best-effort routing hint, so annotate it with data_race().

When a service runs\nfewer threads than it has pools -- e.g. an nfsd configured with fewer\nthreads than the host has NUMA nodes while running in \"pernode\" or\n\"percpu\" mode -- the trailing pools are left with no threads at all.\n\nsvc_xprt_enqueue() selects a pool from the CPU servicing the transport,\nqueues the transport on that pool\u0027s sp_xprts, and only wakes a thread\nfrom the same pool.  Each thread services exclusively its own pool, so a\ntransport that lands on a threadless pool is enqueued on sp_xprts and\nnever picked up: the connection hangs indefinitely.\n\nHave svc_pool_for_cpu() skip pools that currently have no threads,\nfalling back to the next populated pool.
