sys/kern sysv_sem.c
Log:
Make the `nsops' variable in `semop' unsigned. This prevents an
overflow if uap->nsops (which is already unsigned) is over INT_MAX;
consequently, the bounds check below becomes valid. Previously, if a
value over INT_MAX was passed in uap->nsops, the bounds check wouldn't
catch it, and the value would be used to compute copyin()'s third
argument.
