syzbot found a use-after-free in inet6_mc_check [1] The problem here is that inet6_mc_check() uses rcu and read_lock(&iml->sflock) So the fact that ip6_mc_leave_src() is called under RTNL and the socket lock does not help us, we need to acquire iml->sflock in write mode. In the future, we should convert all this stuff to RCU.

[ Upstream commit dc012f3 ] syzbot found a use-after-free in inet6_mc_check [1] The problem here is that inet6_mc_check() uses rcu and read_lock(&iml->sflock) So the fact that ip6_mc_leave_src() is called under RTNL and the socket lock does not help us, we need to acquire iml->sflock in write mode. In the future, we should convert all this stuff to RCU.

hi
i reuse the kernel config (3.4.103+) which works perfecly with A10S olinuxino card to compile 3.4.104+ kernel after compiling i get a error during boot and stuck just after (see attached log)
is there an issue with MMC support on this kernel
regards
