Subject: [PATCH AUTOSEL 5.1 107/141] RDMA/core: Fix race when resolving IP address
Date: Fri, 19 Jul 2019 00:02:12 -0400 [thread overview]
Message-ID: <20190719040246.15945-107-sashal@kernel.org> (raw)
In-Reply-To: <20190719040246.15945-1-sashal@kernel.org>
From: Dag Moxnes <dag.moxnes@oracle.com>
[ Upstream commit d8d9ec7dc5abbb3f11d866e983c4984f5c2de9d6 ]
Use the neighbour lock when copying the MAC address from the neighbour
data struct in dst_fetch_ha.
When not using the lock, it is possible for the function to race with
neigh_update(), causing it to copy an torn MAC address:
rdma_resolve_addr()
rdma_resolve_ip()
addr_resolve()
addr_resolve_neigh()
fetch_ha()
dst_fetch_ha()
memcpy(dev_addr->dst_dev_addr, n->ha, MAX_ADDR_LEN)
and
net_ioctl()
arp_ioctl()
arp_rec_delete()
arp_invalidate()
neigh_update()
__neigh_update()
memcpy(&neigh->ha, lladdr, dev->addr_len)
It is possible to provoke this error by calling rdma_resolve_addr() in a
tight loop, while deleting the corresponding ARP entry in another tight
loop.
Fixes: 51d45974515c ("infiniband: addr: Consolidate code to fetch neighbour hardware address from dst.")
