* USB: add scatter-gather support to usbmonAlan Stern2009-12-112-12/+62
| | | | | | | | | | | | | This patch (as1301) adds support to usbmon for scatter-gather URBs. The text interface looks at only the first scatterlist element, since it never copies more than 32 bytes of data anyway. The binary interface copies as much data as possible up to the first non-addressable buffer.

* USB: usbmon: fix bug in mon_buff_area_shrinkAlan Stern2009-11-181-4/+7
| | | | | | | | | | | | | | | | | | | | | | This patch (as1299b) fixes a bug in an error-handling path of usbmon's binary interface. The storage area for URB data is divided into fixed-size blocks. If an URB's data can't be copied, the area reserved for it should be decreased to the size of the truncated information (rounded up to a block boundary). Rounding up the amount to be removed and subtracting it from the reserved size is definitely the wrong thing to do. Also, when the data for an isochronous URB can't be copied, we can still copy the isoc packet descriptors. In fact the current code does copy the descriptors, but then sets the capture length to 0 so they remain inaccessible. The capture length should be reduced to the length of the descriptors, not set to 0.

* USB: usbmon: end ugly tricks with DMA peekingPete Zaitcev2009-09-236-136/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes crashes when usbmon attempts to access GART aperture. The old code attempted to take a bus address and convert it into a virtual address, which clearly was impossible on systems with actual IOMMUs. Let us not persist in this foolishness, and use transfer_buffer in all cases instead. I think downsides are negligible. The ones I see are: - A driver may pass an address of one buffer down as transfer_buffer, and entirely different entity mapped for DMA, resulting in misleading output of usbmon. Note, however, that PIO based controllers would do transfer the same data that usbmon sees here. - Out of tree drivers may crash usbmon if they store garbage in transfer_buffer. I inspected the in-tree drivers, and clarified the documentation in comments. - Drivers that use get_user_pages will not be possible to monitor. I only found one driver with this problem (drivers/staging/rspiusb). - Same happens with with usb_storage transferring from highmem, but it works fine on 64-bit systems, so I think it's not a concern. At least we don't crash anymore. Why didn't we do this in 2.6.10? That's because back in those days it was popular not to fill in transfer_buffer, so almost all traffic would be invisible (e.g. all of HID was like that). But now, the tree is almost 100% PIO friendly, so we can do the right thing at last. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | | 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.

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.

* usbmon: bus zeroPete Zaitcev2007-04-274-84/+116
| | | | | | | | | | | | | | | | | Add the "bus zero" feature to the usbmon. If a user process specifies bus with number zero, it receives events from all buses. This is useful when we wish to see initial enumeration when a bus is created, typically after a modprobe. Until now, an application had to loop until a new bus could be open, then start capturing on it. This procedure was cumbersome and could lose initial events. Also, often it's too bothersome to find exactly to which bus a specific device is attached. Paolo Albeni provided the original concept implementation.

* USB: add binary API to usbmonPete Zaitcev2007-02-086-55/+1352
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new, "binary" API in addition to the old, text API usbmon had before. The new API allows for less CPU use, and it allows to capture all data from a packet where old API only captured 32 bytes at most. There are some limitations and conditions to this, e.g. in case someone constructs a URB with 1GB of data, it's not likely to be captured, because even the huge buffers of the new reader are finite. Nonetheless, I expect this new capability to capture all data for all real life scenarios. The downside is, a special user mode application is required where cat(1) worked before. I have sample code at http://people.redhat.com/zaitcev/linux/ and Paolo Abeni is working on patching libpcap. This patch was initially written by Paolo and later I tweaked it, and we had a little back-and-forth. So this is a jointly authored patch, but I am submitting this I am responsible for the bugs.

Along with those changes, the patch gets rid of usb_bus_get and usb_bus_put, replacing them with usb_get_hcd and usb_put_hcd. The one interesting aspect is that the dev_set_drvdata call was removed from usb_put_hcd, where it clearly doesn't belong. This means the driver private data won't get reset to NULL.

| | | | | | | | | | | | | | | | | | | | | | | | | The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.

* [PATCH] USB: Let usbmon collect less garbagePete Zaitcev2006-01-041-13/+6Star
| | | | | | | | | | Alan Stern pointed out that (in 2.6 kernel) one successful submission results in one callback, even for ISO-out transfers. Thus, the silly check can be removed from usbmon. This reduces the amount of garbage printed in case of ISO and Interrupt transfers. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] USB: convert usbmon to use usb notifiersGreg Kroah-Hartman2005-10-291-2/+21

* [PATCH] USB: Usbmon setup DMA patchPete Zaitcev2005-09-121-1/+1
| | | | | | | | | | | | | | Alan Stern sent me this patch. It goes on top of the patch the adds mon_dmapeek: http://ftp.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/gregkh-04-usb/usb-usbmon-dma-areas.patch Please be warned about ordering requirements or the build may fail. Actually, mon_dmapeek is generic enough to support SETUP packets too.
