[ Upstream commit 585c91f40d201bc564d4e76b83c05b3b5363fe7e ]
Fix unsafe unaligned pointer usage in usbip network interfaces. usbip tool
build fails with new gcc -Werror=address-of-packed-member checks.
usbip_network.c: In function ‘usbip_net_pack_usb_device’:
usbip_network.c:79:32: error: taking address of packed member of ‘struct usbip_usb_device’ may result in an unaligned pointer value [-Werror=address-of-packed-member]
79 | usbip_net_pack_uint32_t(pack, &udev->busnum);
Fix with minor changes to pass by value instead of by address.

[ 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().

[ 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);

for each function it appears in

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.

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.

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().

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.

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.

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.

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.

"Here's the big set of USB and PHY patches for 3.19-rc1.
The normal churn in the USB gadget area is in here, as well as xhci
and other individual USB driver updates. The PHY tree is also in

All of these have been in linux-next"

Delete a local structure that is only used to be initialized by memset.
A semantic patch that makes this change is as follows:

{

-struct i x;
