* xfrm_user: fix info leak in copy_to_user_auth()Mathias Krause2012-09-20
| | | | | | | | | | | | | copy_to_user_auth() fails to initialize the remainder of alg_name and therefore discloses up to 54 bytes of heap memory via netlink to userland. Use strncpy() instead of strcpy() to fill the trailing bytes of alg_name with null bytes.

* net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200Bjørn Mork2012-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the modes of Huawei E367 has this QMI/wwan interface: I:* If#= 1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=07 Driver=(none) E: Ad=83(I) Atr=03(Int.) MxPS= 64 Ivl=2ms E: Ad=84(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms E: Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=4ms Huawei use subclass and protocol to identify vendor specific functions, so adding a new vendor rule for this combination. The Pantech devices UML290 (106c:3718) and P4200 (106c:3721) use the same subclass to identify the QMI/wwan function. Replace the existing device specific UML290 entries with generic vendor matching, adding support for the Pantech P4200. The ZTE MF683 has 6 vendor specific interfaces, all using ff/ff/ff for cls/sub/prot. Adding a match on interface #5 which is a QMI/wwan interface.

* tcp: restore rcv_wscale in a repair mode (v2)Andrey Vagin2012-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rcv_wscale is a symetric parameter with snd_wscale. Both this parameters are set on a connection handshake. Without this value a remote window size can not be interpreted correctly, because a value from a packet should be shifted on rcv_wscale. And one more thing is that wscale_ok should be set too. This patch doesn't break a backward compatibility. If someone uses it in a old scheme, a rcv window will be restored with the same bug (rcv_wscale = 0). v2: Save backward compatibility on big-endian system. Before the first two bytes were snd_wscale and the second two bytes were rcv_wscale. Now snd_wscale is opt_val & 0xFFFF and rcv_wscale >> 16. This approach is independent on byte ordering.

* pkt_sched: fix virtual-start-time update in QFQPaolo Valente2012-09-19
| | | | | | | | | | | | | | | If the old timestamps of a class, say cl, are stale when the class becomes active, then QFQ may assign to cl a much higher start time than the maximum value allowed. This may happen when QFQ assigns to the start time of cl the finish time of a group whose classes are characterized by a higher value of the ratio max_class_pkt/weight_of_the_class with respect to that of cl. Inserting a class with a too high start time into the bucket list corrupts the data structure and may eventually lead to crashes. This patch limits the maximum start time assigned to a class.

* tcp: flush DMA queue before sk_wait_data if rcv_wnd is zeroMichal Kubeček2012-09-19
| | | | | | | | | | | | | | | | | | | If recv() syscall is called for a TCP socket so that - IOAT DMA is used - MSG_WAITALL flag is used - requested length is bigger than sk_rcvbuf - enough data has already arrived to bring rcv_wnd to zero then when tcp_recvmsg() gets to calling sk_wait_data(), receive window can be still zero while sk_async_wait_queue exhausts enough space to keep it zero. As this queue isn't cleaned until the tcp_service_net_dma() call, sk_wait_data() cannot receive any data and blocks forever. If zero receive window and non-empty sk_async_wait_queue is detected before calling sk_wait_data(), process the queue first. Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.

* bnx2x: fix rx checksum validation for IPv6Michal Schmidt2012-09-18
| | | | | | | | | | | | | | | | | Commit d6cb3e41 "bnx2x: fix checksum validation" caused a performance regression for IPv6. Rx checksum offload does not work. IPv6 packets are passed to the stack with CHECKSUM_NONE. The hardware obviously cannot perform IP checksum validation for IPv6, because there is no checksum in the IPv6 header. This should not prevent us from setting CHECKSUM_UNNECESSARY. Tested on BCM57711.

This can be caused by another node allocating something in the same extent which has been reserved locally. This patch tests for this condition and then skips the remainder of the reservation in this case. This is a relatively rare event, so that it should not affect the general performance improvement which the block reservations provide. The claim_reserved_blks() function also appears not to be able to deal with reservations which cross bitmap boundaries, but that can be dealt with in a future patch since we don't generate boundary crossing reservations currently.

This is because it compares the clock frequency against constants reflecting (boundary / 100). Compare against real boundary frequencies to fix the problem.

This is caused by the (wrong) assumption that RFE in the Status Register is 1 iff there is no byte already ordered (via a dummy TX byte). This lead to the implementation of synchronized byte ordering, e.g.: Dummy-TX - RX - Dummy-TX - RX - ... But since RFE actually stays high after some Dummy-TX, it rather looks like: Dummy-TX - Dummy-TX - RX - Dummy-TX - RX - (RX) The last RX byte is clocked in by the bus controller, but ignored by the kernel when filling the userspace buffer. This patch fixes the issue by asking for RX via Dummy-TX asynchronously. Introducing a separate counter for TX bytes.

The lower file was being released when the eCryptfs file was closed and the dirtied pages could not be written out. - Adds a call to the lower filesystem's ->flush() from ecryptfs_flush(). - Fixes a regression, introduced in 2.6.39, when a file is renamed on top of another file. The target file's inode was not being evicted and the space taken by the file was not reclaimed until eCryptfs was unmounted. * tag 'ecryptfs-3.6-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs: eCryptfs: Copy up attributes of the lower target inode after rename eCryptfs: Call lower ->flush() from ecryptfs_flush() eCryptfs: Write out all dirty pages just before releasing the lower file
