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

2018-08-03T05:55:15+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(). Signed-off-by: Shuah Khan (Samsung OSG) Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

tools/usbip: fixes build with musl libc toolchain

2018-03-22T08:17:56+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 Signed-off-by: Julien BOIBESSOT Acked-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

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

2018-02-03T16:05:42+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

2018-02-03T16:05:42+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. Signed-off-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman

usbip: Fix implicit fallthrough warning

2018-01-31T11:55:50+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.

usbip: fix usbip bind writing random string after command in match_busid

2018-01-02T19:35:15+00:00

commit 544c4605acc5ae4afe7dd5914147947db182f2fb upstream. usbip bind writes commands followed by random string when writing to match_busid attribute in sysfs, caused by using full variable size instead of string length. Signed-off-by: Juan Zea Acked-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman

2016-04-26T22:19:50+00:00

Extract the code from current stub driver backend and a common interface for both stub driver and vudc. This allows to share most of the usbipd code for both of them.

tools: usbip: detach: avoid calling strlen() at each iteration

2015-09-22T19:07:45+00:00

Instead of calling strlen on every iteration of the for loop, just call it once and cache the result in a temporary local variable which will be used in the for loop instead. Signed-off-by: Eric Curtin Signed-off-by: Greg Kroah-Hartman
