[PATCH] ipvs: fix possible use of uninitialized ipvs pointer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5e26b1b3abce[1] moved a derreference on ipvs on sysctl_sloppy_sctp(ipvs)
to before its initialization.

Fix now is to just move ipvs initialization a bit upper.

Fixes: 5e26b1b3abce ("ipvs: support scheduling inverse and icmp SCTP packets")
