tipc: improve size validations for received domain records

2022-02-11T08:09:03Z

commit 9aa422ad326634b76309e8ff342c246800621216 upstream. The function tipc_mon_rcv() allows a node to receive and process domain_record structs from peer nodes to track their views of the network topology. This patch verifies that the number of members in a received domain record does not exceed the limit defined by MAX_MON_DOMAIN, something that may otherwise lead to a stack overflow. tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where we are reading a 32 bit message data length field into a uint16. To avert any risk of bit overflow, we add an extra sanity check for this in that function. We cannot see that happen with the current code, but future designers being unaware of this risk, may introduce it by allowing delivery of very large (> 64k) sk buffers from the bearer layer. This potential problem was identified by Eric Dumazet.

crypto: api - Move cryptomgr soft dependency into algapi

2022-02-11T08:09:03Z

commit c6ce9c5831cae515d375a01b97ae1778689acf19 upstream. The soft dependency on cryptomgr is only needed in algapi because if algapi isn't present then no algorithms can be loaded. This also fixes the case where api is built-in but algapi is built as a module as the soft dependency would otherwise get lost.

KVM: s390: Return error on SIDA memop on normal guest

2022-02-11T08:09:03Z

commit 2c212e1baedcd782b2535a3f86bc491977677c0e upstream. Refuse SIDA memops on guests which are not protected. For normal guests, the secure instruction data address designation, which determines the location we access, is not under control of KVM.

moxart: fix potential use-after-free on remove path

2022-02-11T08:09:03Z

commit bd2db32e7c3e35bd4d9b8bbff689434a50893546 upstream. It was reported that the mmc host structure could be accessed after it was freed in moxart_remove(), so fix this by saving the base register of the device and using it instead of the pointer dereference.

cgroup/cpuset: Fix "suspicious RCU usage" lockdep warning

2022-02-08T17:30:41Z

commit 2bdfd2825c9662463371e6691b1a794e97fa36b4 upstream. It was found that a "suspicious RCU usage" lockdep warning was issued with the rcu_read_lock() call in update_sibling_cpumasks(). It is because the update_cpumasks_hier() function may sleep. So we have to release the RCU lock, call update_cpumasks_hier() and reacquire it afterward. Also add a percpu_rwsem_assert_held() in update_sibling_cpumasks() instead of stating that in the comment.
