ux500: Tee: Use hwmem for memrefs

2012-05-22T09:04:39+00:00

- Instead of kmalloc, hwmem is used when copying memrefs from user space to kernel space. - Fix for a invalid free when calls to secure world fails. - Remove free to memrefs etc in tee_release since they should be handled completely in tee_write.

Pull networking tree from David Miller: 1) ptp_pch driver build broke during this merge window due to missing slab.h header, fix from Geery Uytterhoeven. 2) If ipset passes in a bogus hash table size we crash because the size is not validated properly. Compounding this, gcc-4.7 can miscompile ipset such that even when the user specifies legitimate parameters the tool passes in an out-of-range size to the kernel. Fix from Jozsef Kadlecsik. 3) Users have reported that the netdev watchdog can trigger with pch_gbe devices, and it turns out this is happening because of races in the TX path of the driver leading to the transmitter hanging. Fix from Eric Dumazet, reported and tested by Andy Cress. 4) Novatel USB551L devices match the generic class entries for the cdc ethernet USB driver, but they don't work because they have generic descriptors and thus need FLAG_WWAN to function properly. Add the necessary ID table entry to fix this, from Dan Williams. 5) A recursive locking fix in the USBNET driver added a new problem, in that packet list traversal is now racy and we can thus access unlinked SKBs and crash. Avoid this situation by adding some extra state tracking, from Ming Lei. 6) The rtlwifi conversion to asynchronous firmware loading is racy, fix by reordering the probe procedure. From Larry Finger. Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=43187 7) Fix regressions with bluetooth keyboards by notifying userland properly when the security level changes, from Gustavo Padovan. 8) Bluetooth needs to make sure device connected events are emitted before other kinds of events, otherwise userspace will think there is no baseband link yet and therefore abort the sockets associated with that connection. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: netfilter: ipset: fix hash size checking in kernel ptp_pch: Add missing #include pch_gbe: fix transmit races cdc_ether: add Novatel USB551L device IDs for FLAG_WWAN usbnet: fix skb traversing races during unlink(v2) Bluetooth: mgmt: Fix device_connected sending order Bluetooth: notify userspace of security level change rtlwifi: fix for race condition when firmware is cached

John Linville says: Here are three more fixes that some of my developers are desperate to see included in 3.4... Johan Hedberg went to some length justifyng the inclusion of these two Bluetooth fixes: "The device_connected fix should be quite self-explanatory, but it's actually a wider issue than just for keyboards. All profiles that do incoming connection authorization (e.g. headsets) will break without it with specific hardware. The reason it wasn't caught earlier is that it only occurs with specific Bluetooth adapters. As for the security level patch, this fixes L2CAP socket based security level elevation during a connection. The HID profile needs this (for keyboards) and it is the only way to achieve the security level elevation when using the management interface to talk to the kernel (hence the management enabling patch being the one that exposes this" The rtlwifi fix addresses a regression related to firmware loading, as described in kernel.org bug 43187. It basically just moves a hunk of code to a more appropriate place. Signed-off-by: David S. Miller
