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

2018-08-09T10:20:26+00:00

[ Upstream commit d179f99a651685b19333360e6558110da2fe9bd7 ]

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().

tools/usbip: fixes build with musl libc toolchain

2018-03-22T08:37:16+00:00

[ Upstream commit 77be4c878c72e411ad22af96b6f81dd45c26450a ]

Indeed musl doesn't define old SIGCLD signal name but only new one SIGCHLD.
SIGCHLD is the new POSIX name for that signal so it doesn't change
anything on other libcs.

This fixes this kind of build error:

usbipd.c: In function ‘set_signal’:
usbipd.c:459:12: error: 'SIGCLD' undeclared (first use in this function)
  sigaction(SIGCLD, &act, NULL);
            ^~~~~~
usbipd.c:459:12: note: each undeclared identifier is reported only once
	for each function it appears in
Makefile:407: recipe for target 'usbipd.o' failed
make[3]: *** [usbipd.o] Error 1

usbip: list: don't list devices attached to vhci_hcd

2018-02-07T19:07:57+00:00

commit ef824501f50846589f02173d73ce3fe6021a9d2a upstream.

usbip host lists devices attached to vhci_hcd on the same server
when user does attach over localhost or specifies the server as the
remote.

usbip attach -r localhost -b busid
or
usbip attach -r servername (or server IP)

Fix it to check and not list devices that are attached to vhci_hcd.

usbip: prevent bind loops on devices attached to vhci_hcd

2018-02-07T19:07:57+00:00

commit ef54cf0c600fb8f5737fb001a9e357edda1a1de8 upstream.

usbip host binds to devices attached to vhci_hcd on the same server
when user does attach over localhost or specifies the server as the
remote.

usbip attach -r localhost -b busid
or
usbip attach -r servername (or server IP)

Unbind followed by bind works, however device is left in a bad state with
accesses via the attached busid result in errors and system hangs during
shutdown.

Fix it to check and bail out if the device is already attached to vhci_hcd.

usbip: Fix implicit fallthrough warning

2018-01-31T13:46:13+00:00

commit cfd6ed4537a9e938fa76facecd4b9cd65b6d1563 upstream.

GCC 7 now warns when switch statements fall through implicitly, and with
-Werror enabled in configure.ac, that makes these tools unbuildable.

We fix this by notifying the compiler that this particular case statement
is meant to fall through.
