| * | USB: add binary API to usbmon | Pete Zaitcev | 2007-02-07 | 1 | -1/+38 |
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | [PATCH] USB: update usbmon, fix glued lines | Pete Zaitcev | 2006-06-21 | 1 | -1/+4 |
| | | | | | | | | | | | | | | | | | | 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.

| * | [PATCH] usbmon in 2.6.13: peeking into DMA areas | Pete Zaitcev | 2005-09-08 | 1 | -0/+55 |
| This code looks at urb->transfer_dma, maps the page and takes the data. I am looking for volunteers to contribute architectures other than i386 or to develop an architecure-neutral API for it (or point me that it was done already).
