2008-04-24usbmon: restore mmapPete Zaitcev
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.

2007-10-12USB: reorganize urb->status use in usbmonAlan Stern
This patch (as978) reorganizes the way usbmon uses urb->status. It now accepts the status value as an argument. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-10-12usbmon: Smooth the core codePete Zaitcev
Two things: - mbus can be NULL (in case of bus removal while reader is reading) - Remove a useless assignment Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-10-12USB: avoid urb->pipe in usbmonAlan Stern
This patch (as949) changes the usbmon driver to use the new urb->ep field rather than urb->pipe. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Cc: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-12usbmon: Add class for binary interfacePete Zaitcev
Add a class which allows for an easier integration with udev. This code was originally written by Paolo Abeni, and arrived to my tree as a part of big patch to add binary API on December 18. As I understand, Paolo always meant the class to be a part of the whole thing. This is his udev rule to go along with the patch: KERNEL=="usbmon[0-9]*", NAME="usbmon%n", MODE="0440",OWNER="root",GROUP="bin" Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-05-08header cleaning: don't include smp_lock.h when not usedRandy Dunlap
Remove includes of <linux/smp_lock.h> where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs).

2007-04-27usbmon: bus zeroPete Zaitcev
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. I added the handling of "bus->monitored" flag and generally fixed it up. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-02-07USB: add binary API to usbmonPete Zaitcev
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.

2006-09-27usbmon: don't call mon_dmapeek if DMA isn't being usedAlan Stern
This patch (as755b) fixes a bug in usbmon. Rather than assuming all USB host controllers use DMA, the code will check the usb_bus data structure. If DMA isn't used, we don't want to try peeking into a non-existent DMA buffer! Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-09-27usbcore: trim down usb_bus structureAlan Stern
As part of the ongoing program to flatten out the HCD bus-glue layer, this patch (as771b) eliminates the hcpriv, release, and kref fields from struct usb_bus. hcpriv and release were not being used for anything worthwhile, and kref has been moved into the enclosing usb_hcd structure. 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. It shouldn't cause any problems, since the private data is undefined when no driver is bound. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-06-21[PATCH] USB: update usbmon, fix glued linesPete Zaitcev
This update contains one bug fix: some lines can come out truncated, because of the safety cutoff. This happened because I forgot to update the size when status packets began to be printed. The rest is: - Comments updates - Allow snooping with pkmap on x86_64, which is cache-coherent - Enlarge event buffers (certainly we can have a couple of pages) - Add event counter First touch upon usbmon for 2.6.18.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
