USB: usbmon: fix read(2)

2008-11-20T06:01:35+00:00

There's a bug in the usbmon binary reader: When using read() to fetch the packets and a packet's data is partially read, the next read call will once again return up to len_cap bytes of data. The b_read counter is not regarded when determining the remaining chunk size. So, when dumping USB data with "cat /dev/usbmon0 > usbmon.trace" while reading from a USB storage device and analyzing the dump file afterwards it will get out of sync after a couple of packets.

usbmon: fix tiny race exposed by the fastboot patches

2008-10-17T21:40:57+00:00

usbmon registers the notifier chain, takes the bus lock and then goes to scan the existing devices for hooking up. Unfortunately, if usb_mon gets initialized while USB bus discovery is going on, it's possible that usbmon gets a notifier on one cpu (which runs without USB locks), and the scan is going on and also finds the new bus, resulting in a double sysfs registration, which then produces a WARNING. Pete Zaitcev did the bug diagnostics on this one Signed-off-by: Arjan van de Ven Acked-by: Pete Zaitcev Signed-off-by: Andrew Morton Signed-off-by: Greg Kroah-Hartman

device create: usb: convert device_create_drvdata to device_create

2008-10-16T16:24:45+00:00

Now that device_create() has been audited, rename things back to the original call to be sane. Signed-off-by: Greg Kroah-Hartman

SL*B: drop kmem cache argument from constructor

2008-07-26T19:00:07+00:00

Kmem cache passed to constructor is only needed for constructors that are themselves multiplexeres. Nobody uses this "feature", nor does anybody uses passed kmem cache in non-trivial way, so pass only pointer to object. Non-trivial places are: arch/powerpc/mm/init_64.c arch/powerpc/mm/hugetlbpage.c This is flag day, yes.

device create: usb: convert device_create to device_create_drvdata

2008-07-22T04:54:46+00:00

device_create() is race-prone, so use the race-free device_create_drvdata() instead as device_create() is going away. Signed-off-by: Greg Kroah-Hartman

usbmon: restore mmap

2008-04-25T04:16:43+00:00

Paolo asked to enable the mmap. I kept it off because I'm do not entirely understand how it workse these days after ->nopage etc. But it seems like working somewhat at least. Signed-Off-By: Pete Zaitcev Cc: Paolo Abeni Signed-off-by: Greg Kroah-Hartman
