Subject: [PATCH net 0/3] net/smc: fixes 2022-04-08

Please apply the following patches to netdev's net tree.

Patch 1 fixes two usages of snprintf() with non null-terminated
string which results into an out-of-bounds read.
Pach 2 fixes a syzbot finding where a pointer check was missed
before the call to dev_name().
Patch 3 fixes a crash when already released memory is used as
a function pointer.

Karsten Graul (3):
  net/smc: use memcpy instead of snprintf to avoid out of bounds read
  net/smc: Fix NULL pointer dereference in smc_pnet_find_ib()
  net/smc: Fix af_ops of child socket pointing to released memory
