In the absence of any screams of pain from the usb list, modutils 2.4.1
is released for your enjoyment.
ftp://ftp.<country>.kernel.org/pub/linux/utils/kernel/modutils/v2.4
modutils-2.4.1.tar.gz Source tarball, includes RPM spec file
modutils-2.4.1-1.src.rpm As above, in SRPM format
modutils-2.4.1-1.i386.rpm Compiled with egcs-2.91.66, glibc 2.1.2
modutils-2.4.1-1.sparc.rpm Compiled for combined sparc 32/64
patch-modutils-2.4.1.gz Patch from modutils 2.4.0 to 2.4.1.
Related kernel patches.
patch-2.4.0-hotplug.gz Correctly handle USB modules in kernel 2.4.0.
The fix adds a version number to tables read by
depmod, this affects all kernel hotplug tables,
not just USB. Required for USB on 2.4.0.
patch-2.4.0-persistent.gz Adds persistent data and generic string
support to kernel 2.4.0. Optional.
Changelog extract
* Cast 2*sizeof to int in printf, new gcc warns about this.
* Add an optional version number to kernel tables.
* Handle version 1 and 2 usb device tables.
* man lsmod documents use count -1.
NOTE:
Handling the change of format for the USB tables highlighted the need
for the kernel to include a version number against each table to tell
depmod which format table it is processing. Checking for a change in
table size was not enough. You _must_ apply patch-2.4.0-hotplug to
2.4.0 kernels in order to pick up the new USB table format. You will
also need a new set of USB utilities that understand match_flags.
patch-2.4.0-hotplug hits all hotplug tables, not just USB. The
kernel and modutils changes are forward and backward compatible; old
kernels will run with new modutils and vice versa. The only
combination not supported is USB hotplugging in an unpatched kernel
2.4.0, there is no way for any version of modutils to detect which
format USB table is being used in unpatched 2.4.0 kernels.
patch-2.4.0-hotplug follows for reference, it is also in the URL at the
top of this mail. With any luck this patch will be included in kernel
2.4.1.
