rev. 1.27 of src/sys/compat/linux/linux_ioctl.h: Implement LINUX_SIOCGIFCOUNT and LINUX_SIOCGIFINDEX/LINUX_SIOGIFINDEX. Approved by: re (kensmith)

Add the CAM 'SG' peripheral device. This device implements a subset of the

Linux SCSI SG passthrough device API. The intention is to allow for both running of Linux apps that want to talk to /dev/sg* nodes, and to facilitate porting of apps from Linux to FreeBSD. As such, both native and linuxolator entry points and definitions are provided. Caveats: - This does not support the procfs and sysfs nodes that the Linux SG driver provides. Some Linux apps may rely on these for operation, others may only use them for informational purposes. - More ioctls need to be implemented. - Linux uses a naming scheme of "sg[a-z]" for devices, while FreeBSD uses a scheme of "sg[0-9]". Devfs aliasis (symlinks) are automatically created to link the two together. However, tools like camcontrol only see the native names. - Some operations were originally designed to return byte counts or other data directly as the syscall return value. The linuxolator doesn't appear to support this well, so this driver just punts for these cases. Now that the driver is in place, others are welcome to add missing functionality. Thanks to Roman Divacky for pushing this work along.

- Protect the list of linux ioctl handlers with an sx lock.

- Hold Giant while calling linux ioctl handlers for now as they aren't all known to be MPSAFE yet. - Mark linux_ioctl() MPSAFE.

Now that we don't have a linuxolator on alpha anymore:

Linux compat bits needed to make linux programs use the new ptys :

2006-01-26T01:32:46Z

linux_ioctl.[ch] : Implement LINUX_TIOCGPTN, which returns the pty number linux_stats.c : - Return the magic number for devfs. - In various stats()-related functions, check that we're stating a file in /dev/pts, and if so, change the st_rdev field to match what linux expects to be there for a slave pty device. The glibc checks for this, and their openpty() fails if it is no correct.
