[ Upstream commit 8f44c9a4 ] The lower level nl80211 code in cfg80211 ensures that "len" is between 25 and NL80211_ATTR_FRAME (2304). We subtract DOT11_MGMT_HDR_LEN (24) from "len" so thats's max of 2280. However, the action_frame->data[] buffer is only BRCMF_FIL_ACTION_FRAME_SIZE (1800) bytes long so this memcpy() can overflow. memcpy(action_frame->data, &buf[DOT11_MGMT_HDR_LEN], le16_to_cpu(action_frame->len)); Cc: stable@vger.kernel.org # 3.9.x Fixes: 18e2f61d ("brcmfmac: P2P action frame tx.")

[ Upstream commit ec8add2a ] Currently, when the link for $DEV is down, this command succeeds but the address is removed immediately by DAD (1): ip addr add 1111::12/64 dev $DEV valid_lft 3600 preferred_lft 1800 In the same situation, this will succeed and not remove the address (2): ip addr add 1111::12/64 dev $DEV ip addr change 1111::12/64 dev $DEV valid_lft 3600 preferred_lft 1800 The comment in addrconf_dad_begin() when !IF_READY makes it look like this is the intended behavior, but doesn't explain why: * If the device is not ready: * - keep it tentative if it is a permanent address. * - otherwise, kill it. We clearly cannot prevent userspace from doing (2), but we can make (1) work consistently with (2). addrconf_dad_stop() is only called in two cases: if DAD failed, or to skip DAD when the link is down. In that second case, the fix is to avoid deleting the address, like we already do for permanent addresses. Fixes: 3c21edbd ("[IPV6]: Defer IPv6 device initialization until the link becomes ready.")

[ Upstream commit 6f64ec74 ] Similar to the fix provided by Dominik Heidler in commit 9b3dc0a1 ("l2tp: cast l2tp traffic counter to unsigned") we need to take care of 32bit kernels in dev_get_stats(). When using atomic_long_read(), we add a 'long' to u64 and might misinterpret high order bit, unless we cast to unsigned.

[ Upstream commit db9d8b29 ] The function, skb_complete_tx_timestamp(), used to allow passing in a NULL pointer for the time stamps, but that was changed in commit 62bccb8c ("net-timestamp: Make the clone operation stand-alone from phy timestamping"), and the existing call sites, all of which are in the dp83640 driver, were fixed up. Even though the kernel-doc was subsequently updated in commit 7a76a021 ("net-timestamp: Update skb_complete_tx_timestamp comment"), still a bug fix from Manfred Rudigier came into the driver using the old semantics. Probably Manfred derived that patch from an older kernel version. This fix should be applied to the stable trees as well. Fixes: 81e8f2e9 ("net: dp83640: Fix tx timestamp overflow handling.")

[ Upstream commit c1a4872e ] When qdisc fail to init, qdisc_create would invoke the destroy callback to cleanup. But there is no check if the callback exists really. So it would cause the panic if there is no real destroy callback like the qdisc codel, fq, and so on. Take codel as an example following: When a malicious user constructs one invalid netlink msg, it would cause codel_init->codel_change->nla_parse_nested failed. Then kernel would invoke the destroy callback directly but qdisc codel doesn't define one. It causes one panic as a result. Now add one the check for destroy to avoid the possible panic.

[ Upstream commit 87b60cfa ] Dmitry reported uses after free in qdisc code [1] The problem here is that ops->init() can return an error. qdisc_create_dflt() then call ops->destroy(), while qdisc_create() does _not_ call it. Four qdisc chose to call their own ops->destroy(), assuming their caller would not. This patch makes sure qdisc_create() calls ops->destroy() and fixes the four qdisc to avoid double free.

[ Upstream commit a9332e9a ] There is a clean-up bug in the core comedi module initialization functions, `comedi_init()`. If the `comedi_num_legacy_minors` module parameter is non-zero (and valid), it creates that many "legacy" devices and registers them in SysFS. A failure causes the function to clean up and return an error. Unfortunately, it fails to destroy the "comedi" class that was created earlier. Fix it by adding a call to `class_destroy(comedi_class)` at the appropriate place in the clean-up sequence. Signed-off-by:

[ Upstream commit f991af3d ] The retry logic for netlink_attachskb() inside sys_mq_notify() is nasty and vulnerable: 1) The sock refcnt is already released when retry is needed 2) The fd is controllable by user-space because we already release the file refcnt so we when retry but the fd has been just closed by user-space during this small window, we end up calling netlink_detachskb() on the error path which releases the sock again, later when the user-space closes this socket a use-after-free could be triggered. Setting 'sock' to NULL here should be sufficient to fix it. Reported-by:

[ Upstream commit 236222d3 ] According to the Intel datasheet, the REP MOVSB instruction exposes a pretty heavy setup cost (50 ticks), which hurts short string copy operations. This change tries to avoid this cost by calling the explicit loop available in the unrolled code for strings shorter than 64 bytes. The 64 bytes cutoff value is arbitrary from the code logic point of view - it has been selected based on measurements, as the largest value that still ensures a measurable gain. Micro benchmarks of the __copy_from_user() function with lengths in the [0-63] range show this performance gain (shorter the string, larger the gain): - in the [55%-4%] range on Intel Xeon(R) CPU E5-2690 v4 - in the [72%-9%] range on Intel Core i7-4810MQ Other tested CPUs - namely Intel Atom S1260 and AMD Opteron 8216 - show no difference, because they do not expose the ERMS feature bit.

[ Upstream commit da6c2add ] To set the mux mode of a pin two bits must be set. Up to now this is implemented using the following idiom: writel(mask, reg + CLR); writel(value, reg + SET); . This however results in the mux mode being 0 between the two writes. On my machine there is an IC's reset pin connected to LCD_D20. The bootloader configures this pin as GPIO output-high (i.e. not holding the IC in reset). When Linux reconfigures the pin to GPIO the short time LCD_D20 is muxed as LCD_D20 instead of GPIO_1_20 is enough to confuse the connected IC. The same problem is present for the pin's drive strength setting which is reset to low drive strength before using the right value. So instead of relying on the hardware to modify the register setting using two writes implement the bit toggling using read-modify-write.

[ Upstream commit 97ba26b8 ] The nand_groups table uses different names for the NAND DQS pins than the GROUP() definition in meson8b_cbus_groups (nand_dqs_0 vs nand_dqs0). This prevents using the NAND DQS pins in the devicetree. Fix this by ensuring that the GROUP() definition and the meson8b_cbus_groups use the same name for these pins.

[ Upstream commit b3b51417 ] The usbip stack dynamically allocates the transfer_buffer and setup_packet of each urb that got generated by the tcp to usb stub code. As these pointers are always used only once we will set them to NULL after use. This is done likewise to the free_urb code in vudc_dev.c. This patch fixes double kfree situations where the usbip remote side added the URB_FREE_BUFFER. Cc: stable@vger.kernel.org Signed-off-by:

[ Upstream commit 6836796d ] The USB core and sysfs will attempt to enumerate certain parameters which are unsupported by the au0828 - causing inconsistent behavior and sometimes causing the chip to reset. Avoid making these calls. This problem manifested as intermittent cases where the au8522 would be reset on analog video startup, in particular when starting up ALSA audio streaming in parallel - the sysfs entries created by snd-usb-audio on streaming startup would result in unsupported control messages being sent during tuning which would put the chip into an unknown state.

[ Upstream commit 9e52b325 ] Always try to parse an address, since kstrtoul() will safely fail when given a symbol as input. If that fails (which will be the case for a symbol), try to parse a symbol instead. This allows creating a probe such as: p:probe/vlan_gro_receive 8021q:vlan_gro_receive+0 Which is necessary for this command to work: perf probe -m 8021q -a vlan_gro_receive Link: http://lkml.kernel.org/r/fd72d666f45b114e2c5b9cf7e27b91de1ec966f1.1498122881.git.sd@queasysnail.net Cc: stable@vger.kernel.org Fixes: 413d37d1 ("tracing: Add kprobe-based event tracer") Acked-by:
