Hi folks,
I managed to get a 64-bit Oracle instantclient running under 64-bit Linux so I
can connect to an Oracle database using the Oracle client "sqlplus".
Now, whenever I run sqlplus, I get this message in /var/log/messages:
kernel: linux: pid 92000 (sqlplus): ioctl fd=3, cmd=0x1268 ('',104) is not
implemented
0x1268 is BLKSSZGET according to linux_ioctl.h.
The message is harmless as sqlplus seems to be working correctly, but I would
like to get rid of it and learn new things along the way.
I think the message comes from this code:
https://github.com/freebsd/freebsd/blob/master/sys/compat/linux/linux_ioctl.c#L3606
Apparently, the Linux compat code does not implement the ioctl() system call at
all. Is this a deliberate choice? I have no idea how this code works, or the
security implications of changing it, but it seems like a minor change to
forward linux_ioctl_args to FreeBSD ioctl()?
Erik
