| |
Hi,
I'm working with usbip and I sometimes see a stall when I run the "lsusb" command from the userspace. I added some debug messages and it seems that the kernel_recvmsg() in http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/staging/usbip/usbip_common.c;h=210ef16bab8d271a52e5d36cd1994aad57ad99e1;hb=HEAD
This is the only place I could find where the TCP messages are arriving in the usbip code.
What happens if a message does not arrive? Does it stall forever? If yes, how can the kernel_recvmsg() call changed to handle some timeout?
