Hello,
We are writing some application code for a custom SCSI device, using
the generic SCSI driver (sg.h). The "scsi-programming-howto" mentions
that it may be a good idea to block SIGINT inbetween the "indivisible"
write() and read() that define each generic operation.
Is it still necessary to do this in the kernel used by RedHat 5.2? I
experimented with breaking the write/read sequence manually, and did
not observe anything bad to happen.
Also, merely blocking SIGINT would hardly seem adaquate protection if
any kind of broken write/read sequence really was going to be fatal to
the kernel.
Thanks,
-alan
