CVS commit: src/sys/kern

[Matthias Drochner <drochner%netbsd.org@localhost>]

Module Name:    src
Committed By:   drochner
Date:           Tue Sep 16 15:55:28 UTC 2003

Modified Files:
        src/sys/kern: sys_generic.c

Log Message:
Take into account the possibility that the ktrace flags can change
during a read(v)/write(v). If that happeded, we either passed a NULL
pointer or a pointer to something uninitialized as iov to ktrace,
or we got a memory leak. In read/write (w/o -v) we zero-initialize
the iov now to limit damage, in the -v calls the (dynamically allocated)
pointer is checked after the I/O.
