tools/usbip: fixes build with musl libc toolchain

2018-05-23T01:33:46Z

[ 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

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

2018-03-01T03:09:47Z

[ Upstream commit ef824501f50846589f02173d73ce3fe6021a9d2a ] 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

2018-03-01T03:09:47Z

[ Upstream commit ef54cf0c600fb8f5737fb001a9e357edda1a1de8 ] 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. Cc: stable@vger.kernel.org Signed-off-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin

usbip: Fix implicit fallthrough warning

2018-03-01T03:09:40Z

[ Upstream commit cfd6ed4537a9e938fa76facecd4b9cd65b6d1563 ] 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

2018-03-01T00:32:18Z

[ Upstream commit 544c4605acc5ae4afe7dd5914147947db182f2fb ] 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.

usbip: remove unneeded structure

2014-12-03T00:15:02Z

Delete a local structure that is only used to be initialized by memset. A semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ identifier x,i; @@ { ... when any -struct i x; <+... when != x - memset(&x,...); ...+> } // Signed-off-by: Julia Lawall Acked-by: Valentina Manea Signed-off-by: Greg Kroah-Hartman
