cdc-phonet: Don't leak in usbpn_open

2012-08-08T23:04:47+00:00

We allocate memory for 'req' with usb_alloc_urb() and then test
'if (!req || rx_submit(pnd, req, GFP_KERNEL | __GFP_COLD))'.
If we enter that branch due to '!req' then there is no problem. But if
we enter the branch due to 'req' being != 0 and the 'rx_submit()' call
being false, then we'll leak the memory we allocated.
Deal with the leak by always calling 'usb_free_urb(req)' when entering
the branch. If 'req' happens to be 0 then the call is harmless, if it
is not 0 then we free the memory we allocated but don't need.

cdc-ncm: tag Ericsson WWAN devices (eg F5521gw) with FLAG_WWAN

2012-08-04T03:32:30+00:00

Hello,

looking at http://sourceforge.net/apps/mediawiki/mbm/index.php?title=Main_Page#Supported_devices, there are branded Ericsson devices from Dell and Toshiba.

The to-be-added vendor IDs are 0x413c for Dell and 0x0930 for Toshiba.

Please find attached a patch to add these vendor IDs.

netvm: propagate page->pfmemalloc from skb_alloc_page to skb

2012-08-01T01:42:46+00:00

The skb->pfmemalloc flag gets set to true iff during the slab allocation
of data in __alloc_skb that the the PFMEMALLOC reserves were used.  If
page splitting is used, it is possible that pages will be allocated from
the PFMEMALLOC reserve without propagating this information to the skb.
This patch propagates page->pfmemalloc from pages allocated for fragments
to the skb.

It works by reintroducing and expanding the skb_alloc_page() API to take
an skb.  If the page was allocated from pfmemalloc reserves, it is
automatically copied.  If the driver allocates the page before the skb, it
should call skb_propagate_pfmemalloc() after the skb is allocated to
ensure the flag is copied properly.

Failure to do so is not critical.  The resulting driver may perform slower
if it is used for swap-over-NBD or swap-over-NFS but it should not result
in failure.

USB: kaweth.c: use GFP_ATOMIC under spin_lock

2012-07-27T20:45:50+00:00

The problem is that we call this with a spin lock held.  The call tree
is:
	kaweth_start_xmit() holds kaweth->device_lock.
	-> kaweth_async_set_rx_mode()
	   -> kaweth_control()
	      -> kaweth_internal_control_msg()

The kaweth_internal_control_msg() function is only called from
kaweth_control() which used GFP_ATOMIC for its allocations.

cdc-ncm: tag Ericsson WWAN devices (eg F5521gw) with FLAG_WWAN

2012-07-24T20:55:38+00:00

Tag Ericsson NCM devices as WWAN modems, since they almost certainly all
are.  This way userspace clients know that the device requires further
setup on the AT-capable serial ports before connectivity is available.

asix: Rework reading from EEPROM

2012-07-19T17:48:07+00:00

The current code for reading the EEPROM via ethtool in the asix
driver has a few issues. It cannot handle odd length values
(accesses must be aligned at 16 bit boundaries) and interprets the
offset provided by ethtool as 16 bit word offset instead as byte offset.

The new code for asix_get_eeprom() introduced by this patch is
modeled after the code in
drivers/net/ethernet/atheros/atl1e/atl1e_ethtool.c
and provides read access to the entire EEPROM with arbitrary
offsets and lengths.
