There is a race if a CPU is offlined or onlined after the loop, but before register_hotcpu_notifier. The race might result in the absence of a platform_device+sysfs interface for an online CPU, or the presence of a platform_device+sysfs interface for an offline CPU. A similar race occurs during coretemp_exit, after the module calls unregister_hotcpu_notifier, but before it unregisters all devices, a CPU might offline and a device for an offline CPU will exist for a short while. This fix surrounds for_each_online_cpu and register_hotcpu_notifier with get_online_cpus+put_online_cpus; and surrounds unregister_hotcpu_notifier and device unregistering with get_online_cpus+put_online_cpus.

CMD_PROTOCOL_ERR may be received from the Smart Array for any commands destined for an external RAID controller such as a P2000, or commands destined for tape drives or CD/DVD-ROM drives, if for instance a cable is disconnected. This mostly affects multipath configurations, as disconnecting a cable on a non-multipath configuration is not going to do anything good regardless of whether CMD_PROTOCOL_ERR is handled correctly or not. Not handling CMD_PROTOCOL_ERR correctly in a multipath configaration involving external RAID controllers may cause data corruption, so this is quite a serious bug. This bug should not normally cause a problem for direct attached disk storage. Signed-off-by: Stephen M.

One of the bits in the chip initialization is being used by the latest firmware to control overflow packets. When this control bit gets enabled erroneously, it would ultimately result in a bad packet placement which would cause the bnx2 driver to dereference a NULL ptr in the placement handler. This can happen under certain stress I/O environment under the Linux iSCSI offload operation. This change only affects Broadcom's 5709 chipset.

But if there are some HighMem pages in table->sgl you can not get virtual address by sg_virt. So, sg_virt(sg_elem) may return NULL value. This will cause QEMU exit when virtqueue_map_sg is called in QEMU because an invalid GPA is passed by virtqueue. Two solutions are discussed here: http://lkml.indiana.edu/hypermail/linux/kernel/1207.3/00675.html Finally, value assignment approach was adopted because: Value assignment creates a well-formed scatterlist, because the termination marker in source sg_list has been set in blk_rq_map_sg(). The last entry of the source sg_list is just copied to the the last entry in destination list. Note that, for now, virtio_ring does not care about the form of the scatterlist and simply processes the first out_num + in_num consecutive elements of the sg[] array. I have tested the patch on my workstation. QEMU would not crash any more.

| * | | edac_mc: edac_mc_free() cannot assume mem_ctl_info is registered in sysfs.Shaun Ruffell2012-09-231-20/+39

Since commit 7a623c039 ("edac: rewrite the sysfs code to use struct device") edac_mc_alloc() no longer initializes embedded kobjects in struct mem_ctl_info. Therefore edac_mc_free() can no longer simply decrement a kobject reference count to free the allocated memory unless the memory controller driver module had also called edac_mc_add_mc(). Now edac_mc_free() will check if the newly embedded struct device has been registered with sysfs before using either the standard device release functions or freeing the data structures itself with logic pulled out of the error path of edac_mc_alloc().

Should be "row" and "tot_csrows" respectively. Which means either memory leak, or out-of-bound reads (which if does not trigger an immediate page fault error, will further lead to kfree() on random addresses). L425: The inner loop is reusing the same iterator "chn" as the outer loop, which could lead to premature end of the outer loop, and hence memory leak. L429: The array index 'i' in mci->csrows[i] is a temporary value used in previous loops, and won't change at all in the current loop. Which means either out-of-bound read and possibly kfree(random number), or the same mci->csrows[i] get freed once and again, and possibly double free for the kfree(csr) in L427. L426/L427: a kfree(csr->channels) is needed in between to avoid leaking the memory. The buggy code was introduced by commit de3910eb ("edac: change the mem allocation scheme to make Documentation/kobject.txt happy") in the 3.6-rc1 merge window.

After that commit, hid-core discards any incoming packet that arrives while hid driver's probe function is being executed. This broke the enumeration process of hid-logitech-dj, that must receive control packets in-band with the mouse and keyboard packets. Discarding mouse or keyboard data at the very begining is usually fine, but it is not the case for control packets. This patch forces a re-enumeration of the paired devices when a packet arrives that comes from an unknown device. Based on a patch originally written by Benjamin Tissoires.

Fix this by generalizing the generation count invalidation scheme used by ipv4. From Nicolas Dichtel. 3) When repairing TCP sockets, we need to allow to restore not just the send window scale, but the receive one too. Extend the existing interface to achieve this in a backwards compatible way. From Andrey Vagin. 4) A fix for FCOE scatter gather feature validation erroneously caused scatter gather to be disabled for things like AOE too. From Ed L Cashin. 5) Several cases of mishandling of error pointers, from Mathias Krause, Wei Yongjun, and Devendra Naga. 6) Fix gianfar build, from Richard Cochran. 7) CAP_NET_* failures should return -EPERM not -EACCES, from Zhao Hongjiang. 8) Hardware reset fix in janz-ican3 CAN driver, from Ira W Snyder. 9) Fix oops during rmmod in ti_hecc CAN driver, from Marc Kleine-Budde. 10) The removal of the conditional compilation of the clk support code in the stmmac driver broke things. This is because the interfaces used are the ones that don't also perform the enable/disable of the clk. Fix from Stefan Roese. 11) The QFQ packet scheduler can record out of range virtual start times, resulting later in misbehavior and even crashes. Fix from Paolo Valente. 12) If MSG_WAITALL is used with IOAT DMA under TCP, we can wedge the receiver when the advertised receive window goes to zero. Detect this case and force the processing of the IOAT DMA queue when it happens to avoid getting stuck. Fix from Michal Kubecek. 13) batman-adv assumes that test_bit() returns only 0 or 1, but this is not true for x86 (which returns -1 or 0, via the 'sbb' instruction). Fix from Linus Lussing. 14) Fix small packet corruption in e1000, from Tushar Dave. 15) make_blackhole() in the IPSEC policy code can do one read unlock too many, fix from Li RongQing. 16) The new tcp_try_coalesce() code introduced a bug in TCP URG handling, fix from Eric Dumazet. 17) Fix memory leak in __netif_receive_skb() when doing zerocopy and when hit an OOM condition. From Michael S Tsirkin. 18) netxen blindly deferences pdev->bus->self, which is not guarenteed to be non-NULL. Fix from Nikolay Aleksandrov. 19) Fix a performance regression caused by mistakes in ipv6 checksum validation in the bnx2x driver, fix from Michal Schmidt. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (45 commits) net/stmmac: Use clk_prepare_enable and clk_disable_unprepare net: change return values from -EACCES to -EPERM net/irda: sh_sir: fix return value check in sh_sir_set_baudrate() stmmac: fix return value check in stmmac_open_ext_timer() gianfar: fix phc index build failure ipv6: fix return value check in fib6_add() bnx2x: remove false warning regarding interrupt number can: ti_hecc: fix oops during rmmod can: janz-ican3: fix support for older hardware revisions net: do not disable sg for packets requiring no checksum aoe: assert AoE packets marked as requiring no checksum at91ether: return PTR_ERR if call to clk_get fails xfrm_user: don't copy esn replay window twice for new states xfrm_user: ensure user supplied esn replay window is valid xfrm_user: fix info leak in copy_to_user_tmpl() xfrm_user: fix info leak in copy_to_user_policy() xfrm_user: fix info leak in copy_to_user_state() xfrm_user: fix info leak in copy_to_user_auth() net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200 tcp: restore rcv_wscale in a repair mode (v2) ...

By this, calling clk_prepare and clk_unprepare was removed. clk_{un}prepare is mandatory for platforms using common clock framework. Since these drivers are used by SPEAr platform, which supports common clock framework, add clk_{un}prepare() support for them. Otherwise the clocks are not correctly en-/disabled and ethernet support doesn't work.

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. Signed-off-by: Michal Schmidt <mschmidt@redhat.com> Acked-by: Eric Dumazet <edumazet@google.com> Acked-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

Linville says: ==================== This is a batch of fixes intended for the 3.6 stream. Arend van Spriel sends a simple thinko fix to correct a constant, preventing the setting of an invalid power level. Colin Ian King gives us a simple allocation failure check to avoid a NULL pointer dereference. Felix Fietkau sends another ath9k tx power patch, this time disabling a feature that has been reported to cause rx problems. Hante Meuleman provides a pair of endian fixes for brcmfmac. Larry Finger offers an rtlwifi fix that avoids a system lockup related to loading the wrong firmware for RTL8188CE devices. These have been in linux-next for a few days and I think they should be included in the final 3.6 kernel if possible. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
