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

2018-08-06T14:24:31Z

[ 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

2018-03-22T08:23:28Z

[ 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

2018-02-03T16:04:30Z

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

2018-02-03T16:04:30Z

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 potential format overflow in userspace tools

2018-01-31T11:06:07Z

commit e5dfa3f902b9a642ae8c6997d57d7c41e384a90b upstream. The usbip userspace tools call sprintf()/snprintf() and don't check for the return value which can lead the paths to overflow, truncating the final file in the path. More urgently, GCC 7 now warns that these aren't checked with -Wformat-overflow, and with -Werror enabled in configure.ac, that makes these tools unbuildable. This patch fixes these problems by replacing sprintf() with snprintf() in one place and adding checks for the return value of snprintf().

usbip: Fix implicit fallthrough warning

2018-01-31T11:06:07Z

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: prevent vhci_hcd driver from leaking a socket pointer address

2018-01-31T11:06:07Z

commit 2f2d0088eb93db5c649d2a5e34a3800a8a935fc5 upstream. When a client has a USB device attached over IP, the vhci_hcd driver is locally leaking a socket pointer address via the /sys/devices/platform/vhci_hcd/status file (world-readable) and in debug output when "usbip --debug port" is run. Fix it to not leak. The socket pointer address is not used at the moment and it was made visible as a convenient way to find IP address from socket pointer address by looking up /proc/net/{tcp,tcp6}. As this opens a security hole, the fix replaces socket pointer address with sockfd. Reported-by: Secunia Research Signed-off-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman

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

2018-01-02T19:33:26Z

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

Merge tag 'usb-for-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

Felipe writes: usb: patches for v4.4 merge window This pull request is large with a total of 136 non-merge commits. Because of its size, we will only describe the big things in broad terms. Many will be happy to know that dwc3 is now almost twice as fast after some profiling and speed improvements. Also in dwc3, John Youn from Synopsys added support for their new DWC USB3.1 IP Core and the HAPS platform which can be used to validate it. A series of patches from Robert Baldyga cleaned up uses of ep->driver_data as a flag for "claimed endpoint" in favor of the new ep->claimed flag. Sudip Mukherjee fixed a ton of really old problems on the amd5536udc driver. That should make a few people happy. Heikki Krogerus worked on converting dwc3 to the unified device property interface. Together with these, there's a ton of non-critical fixes, typos and stuff like that. Signed-off-by: Felipe Balbi
