uas: Set max_sectors_240 quirk for ASM1053 devices

2015-05-13T12:14:28+00:00

commit 8e779c6c4a398763c21371fe40f649206041dc1e upstream.

Testing has shown that ASM1053 devices do not work properly with transfers
larger than 240 sectors, so set max_sectors to 240 on these.

uas: Add US_FL_MAX_SECTORS_240 flag

2015-05-13T12:14:28+00:00

commit ee136af4a064c2f61e2025873584d2c7ec93f4ae upstream.

The usb-storage driver sets max_sectors = 240 in its scsi-host template,
for uas we do not want to do that for all devices, but testing has shown
that some devices need it.

This commit adds a US_FL_MAX_SECTORS_240 flag for such devices, and
implements support for it in uas.c, while at it it also adds support
for US_FL_MAX_SECTORS_64 to uas.c.

uas: Allow uas_use_uas_driver to return usb-storage flags

2015-05-13T12:14:28+00:00

commit a5011d44f0e1117a6db14b19b57c51f8be5673a0 upstream.

uas_use_uas_driver may set some US_FL_foo flags during detection, currently
these are stored in a local variable and then throw away, but these may be
of interest to the caller, so add an extra parameter to (optionally) return
the detected flags, and use this in the uas driver.

usb: chipidea: otg: remove mutex unlock and lock while stop and start role

2015-05-13T12:14:26+00:00

commit a5a356cee89f86ff86cc3ce24136ca1f802c1bf1 upstream.

Wrongly release mutex lock during otg_statemachine may result in re-enter
otg_statemachine, which is not allowed, we should do next state transtition
after previous one completed.

cdc-acm: prevent infinite loop when parsing CDC headers.

2015-05-13T12:14:25+00:00

commit 0d3bba0287d4e284c3ec7d3397e81eec920d5e7e upstream.

Phil and I found out a problem with commit:

  7e860a6e7aa6 ("cdc-acm: add sanity checks")

It added some sanity checks to ignore potential garbage in CDC headers but
also introduced a potential infinite loop.  This can happen at the first
loop iteration (elength = 0 in that case) if the description isn't a
DT_CS_INTERFACE or later if 'buffer[0]' is zero.

It should also be noted that the wrong length was being added to 'buffer'
in case 'buffer[1]' was not a DT_CS_INTERFACE descriptor, since elength was
assigned after that check in the loop.

A specially crafted USB device could be used to trigger this infinite loop.
