usbip: tools: fix atoi() on non-null terminated string

2018-10-18T17:44:39+00:00

Currently the call to atoi is being passed a single char string
that is not null terminated, so there is a potential read overrun
along the stack when parsing for an integer value.  Fix this by
instead using a 2 char string that is initialized to all zeros
to ensure that a 1 char read into the string is always terminated
with a \0.

Detected by cppcheck:
"Invalid atoi() argument nr 1. A nul-terminated string is required."

usbip: fix vhci_hcd controller counting

2018-10-02T19:05:29+00:00

Without this usbip fails on a machine with devices
that lexicographically come after vhci_hcd.

ie.
  $ ls -l /sys/devices/platform
  ...
  drwxr-xr-x. 4 root root    0 Sep 19 16:21 serial8250
  -rw-r--r--. 1 root root 4096 Sep 19 23:50 uevent
  drwxr-xr-x. 6 root root    0 Sep 20 13:15 vhci_hcd.0
  drwxr-xr-x. 4 root root    0 Sep 19 16:22 w83627hf.656

Because it detects 'w83627hf.656' as another vhci_hcd controller,
and then fails to be able to talk to it.

Note: this doesn't actually fix usbip's support for multiple
controllers... that's still broken for other reasons
("vhci_hcd.0" is hardcoded in a string macro), but is enough to
actually make it work on the above machine.

usbip: usbip_detach: fix to check for invalid ports

2018-05-31T10:44:39+00:00

usbip detach doesn't check for invalid ports and ports that are already
detached. It attempts to remove state file(s) without validating the port
and sends detach request to the driver for ports that are already detached.

Add check for invalid ports (port > maxports) and ports that are already
detached (status == VDEV_ST_NULL). Don't remove state files and don't send
detach request for invalid ports and ports that are already detached.

Add error and information messages that make sense.

usbip: usbip_detach: Fix memory, udev context and udev leak

2018-05-31T10:44:39+00:00

detach_port() fails to call usbip_vhci_driver_close() from its error
path after usbip_vhci_detach_device() returns failure, leaking memory
allocated in usbip_vhci_driver_open() and holding udev_context and udev
references. Fix it to call usbip_vhci_driver_close().

usbip: dynamically allocate idev by nports found in sysfs

2018-05-31T10:43:14+00:00

As the amount of available ports varies by the kernels build
configuration. To remove the limitation of the fixed 128 ports
we allocate the amount of idevs by using the number we get
from the kernel.

usbip: tools: usbipd: exclude exported devices from exportable device list

2018-03-22T12:08:20+00:00

usbipd includes exported devices in response to exportable device list.
Exclude exported devices from exportable device list to avoid:

- import requests for devices that are exported only to fail the request.
- revealing devices that are imported by a client to another client.

usbip: tools: change to use new error codes in server reply messages

2018-03-09T17:17:09+00:00

Changed usbip_network, usbip_attach, usbip_list, and usbipd to use
and propagate the new error codes in server reply messages.

usbip_net_recv_op_common() is changed to take a pointer to status
return the status returned in the op_common.status to callers.

usbip_attach and usbip_list use the common interface to print error
messages to indicate why the request failed.

With this change the messages say why a request failed:

- when a client requests a device that is already exported:

usbip attach -r server_name -b 3-10.2
usbip: error: Attach Request for 3-10.2 failed - Device busy (exported)

- when a client requests a device that isn't exportable,

usbip attach -r server_name -b 3-10.4
usbip: error: Attach Request for 3-10.4 failed - Device not found
