17 years agoxen: disable vdso "nosegneg" on native boot
Roland McGrath [Fri, 20 Jul 2007 07:31:43 +0000 (00:31 -0700)]
xen: disable vdso "nosegneg" on native boot

One of the nice ideas behind paravirt is that CONFIG_XEN=y can be included
in a standard configuration and be no worse for native booting than as a
Xen guest.  The glibc feature that supports the vDSO "nosegneg" note is
designed specifically to make this easy.  You just have to flip one bit at
boot time.  This patch makes Xen flip the bit, so a CONFIG_XEN=y kernel on
bare hardware does not make glibc use the less-optimized library builds.

USB: Remove pointless conditional in drivers/usb/serial/io_ti.c::edge_shutdown()

Coverity scan found (CID: 1708) this in
drivers/usb/serial/io_ti.c::edge_shutdown() :

...
2797  for (i=0; i < serial->num_ports; ++i) {

2803  }
2804  usb_set_serial_port_data(serial->port[i], NULL);
2805  }
...

It's complaining that we dereference 'edge_port' in line 2799 which
makes the test of that pointer against NULL in 2800 pointless, since if
edge_port was actually NULL we'd have crashed already before reaching
line 2800.
Reading the edge_open() function it seems to me that the pointer
returned by usb_get_serial_port_data(serial->port[i]) and stored in
'edge_port' can never actually be NULL here, so the test is entirely
superfluous (even if it could be NULL it would be pointless here,
ignoring the then possible crash in that case, since both
edge_buf_free() and kfree() can handle being passed NULL pointers.

This patch removes the pointless conditional (and also makes a few
tiny style corrections now that I was in the area anyway).

USB: add "descriptors" binary sysfs attribute

This patch (as934) adds a new readonly binary sysfs attribute file
called "descriptors" for each USB device.  The attribute contains the
device descriptor followed by the raw descriptor entry (config plug
subsidiary descriptors) for the current configuration.

Having this information available in fixed-format binary makes life a
lot easier for user programs by avoiding the need to open, read, and
parse multiple sysfs text files.

The information in this attribute file is much like that in usbfs's
device file, but there are some significant differences:

The 2-byte fields in the device descriptor are left in
little-endian byte order, as they appear on the bus and
in the kernel.

Only one raw descriptor set is presented, that of the
current configuration.

Opening this file will not cause a suspended device to be
autoresumed.

The last item in particular should be a big selling point for libusb,
which currently forces all USB devices to be resumed as it scans the
device tree.

after all the active endpoints have been scanned.

The status of a completed URB is kept in a local variable
and copied to urb->status only when the URB is about to be
given back.

-EREMOTEIO error status for control transfers is set after
