USB core: don't match interface descriptors for vendor-specific devices
This patch (as804) makes USB driver matching ignore the interface
class, subclass, and protocol if the device class is Vendor Specific.
Drivers can override this policy by specifying a Vendor ID as part
of the match; then vendor-specific matches are allowed.
Linus Walleij has reported a problem this patch fixes. When a
particular mass-storage device is switched from mass-storage mode to
Media Transfer Protocol, the interface class remains set to mass-storage
and usb-storage binds to it erroneously, even though the device class
changes to Vendor-Specific.
This may cause a problem for some drivers until their match records can
be updated to include Vendor IDs. But if it does, then those records
were broken to begin with.

usb hub: fix root hub code so it takes more than 15 devices per root hub
Wireless USB Host Controllers accept a large number of devices per
host, which shows up as a large number of ports in its root hub.
When the number of ports in a hub device goes over 16, the activation
of the hub fails with the cryptic message in klogd.
hub 2-0:1.0: activate --> -22
Following this further, it was seen that:
hub_probe()
hub_configure()
generates pipe number
pseudo allocates buffer 'maxp' bytes in size using usb_maxpacket()
The endpoint descriptor for a root hub interrupt endpoint is
declared in
drivers/usb/core/hcd.c:hs_rh_config_descriptor and declares it
to be size two (supporting 15 devices max).
hub_activate()
usb_hcd_submit_urb()
rh_urb_enqueue()
urb->pipe is neither int nor ctl, so it errors out
rh_queue_status()
Returns -EINVAL because the buffer length is smaller
than the minimum needed to report all the hub port
bits as in accordance with USB2.0[11.12.3]. There has
to be trunc((PORTS + 1 + 7) / 8) bytes of space at
least.
Alan Stern confirmed that the reason for reading maxpktsize and not
the right amount is because some hubs are known to return more data
and thus cause overflow.
So this patch simply changes the code to make the interrupt endpoint's
max packet size be at least the minimum required by USB_MAXCHILDREN
(instead of a fixed magic number) and add documentation for that. This
way we are always ahead of the limit.
Current Wireless USB host hardware (Intel i1480 for example) allows up
to 22 devices to connect, thus bringing up the max number of children
in the WUSB Host Controller to 22 'fake' ports. Upcoming hardware
might raise that limit.
Makes almost no difference to go to 31, as the bit arrays are
byte-aligned (plus an extra bit in general), so 22 bits fit in 4 bytes
as 31 do.
As well, the only other array that depends on USB_MAXCHILDREN is
'struct usb_hub->indicator'. By declaring it 'u8' instead of 'enum
hub_led_mode', we reduce the size of each entry from 4 bytes (in i386)
to 1, which will add as we when are doubling USB_MAXCHILDREN
(with 16 the size of that array is 64 bytes, with 31 would be 128; by
using u8 that goes down to 31 bytes).

pass to our modified execvp() a preallocated buffer. This fixes a real bug
and works very well in testing (I've seen indirectly warning messages from the
forked thread - they went on the pipe connected to its stdout and where read
as a number by UML, when calling read_output(). I verified the obtained

The added use of __cant_sleep() is not a new bug since __cant_sleep() is

better but it would require huge change, stating that this function must not
be called in atomic context and can sleep is a better idea (will make sure of

The Kconfig help for INITRAMFS_SOURCE claims that you can specify multiple
space-separated sources in order to allow unprivileged users to build an
image. There are two bugs in the current implementation that prevent this
from working.
First, we pass "file1 dir2" to the gen_initramfs_list.sh script, which it
obviously can't open.
Second, gen_initramfs_list.sh -l outputs multiple definitions for
deps_initramfs -- one for each argument.
