In function dcbnl_cee_fill(), returns the value of variable err on errors. However, on some error paths (e.g. nla put fails), its value may be 0. It may be better to explicitly set a negative errno to variable err before returning. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=188881Signed-off-by:

Pull ARM SoC fixes from Arnd Bergmann: "This should be the last set of bugfixes for arm-soc in v4.9. None of these are critical regressions, but it would be nice to still get them merged. - On the Juno platform, the idle latency was described wrong, leading to suboptimal cpuidle tuning. - Also on the same platform, PCI I/O space was set up incorrectly and could not work. - On the sti platform, a syntactically incorrect DT entry caused warnings. - The newly added 'gr8' platform has somewhat confusing file names, which we rename for consistency" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: arm64: dts: juno: fix cluster sleep state entry latency on all SoC versions arm64: dts: juno: Correct PCI IO window ARM: dts: STiH407-family: fix i2c nodes ARM: gr8: Rename the DTSI and relevant DTS -

CAP_NET_ADMIN users should not be allowed to set negative sk_sndbuf or sk_rcvbuf values, as it can lead to various memory corruptions, crashes, OOM... Note that before commit 82981930 ("net: cleanups in sock_setsockopt()"), the bug was even more serious, since SO_SNDBUF and SO_RCVBUF were vulnerable. This needs to be backported to all known linux kernels. Again, many thanks to syzkaller team for discovering this gem. Signed-off-by:

Qian Zhang (张谦) reported a potential socket buffer overflow in tipc_msg_build() which is also known as CVE-2016-8632: due to insufficient checks, a buffer overflow can occur if MTU is too short for even tipc headers. As anyone can set device MTU in a user/net namespace, this issue can be abused by a regular user. As agreed in the discussion on Ben Hutchings' original patch, we should check the MTU at the moment a bearer is attached rather than for each processed packet. We also need to repeat the check when bearer MTU is adjusted to new device MTU. UDP case also needs a check to avoid overflow when calculating bearer MTU.

Commit bfe9b9d2 ("cdc_ether: Improve ZTE MF823/831/910 handling") introduced a work-around in usbnet_cdc_status() for devices that exported cdc carrier on twice on connect. Before the commit, this behavior caused the link state to be incorrect. It was assumed that all CDC Ethernet devices would either export this behavior, or send one off and then one on notification (which seems to be the default behavior). Unfortunately, it turns out multiple devices sends a connection notification multiple times per second (via an interrupt), even when connection state does not change. This has been observed with several different USB LAN dongles (at least), for example 13b1:0041 (Linksys). After bfe9b9d2, the link state has been set as down and then up for each notification. This has caused a flood of Netlink NEWLINK messages and syslog to be flooded with messages similar to: cdc_ether 2-1:2.0 eth1: kevent 12 may have been dropped This commit fixes the behavior by reverting usbnet_cdc_status() to how it was before bfe9b9d2. The work-around has been moved to a separate status-function which is only called when a known, affect device is detected. v1->v2: * Do not open-code netif_carrier_ok() (thanks Henning Schild). * Call netif_carrier_off() instead of usb_link_change(). This prevents calling schedule_work() twice without giving the work queue a chance to be processed (thanks Bjørn Mork). Fixes: bfe9b9d2 ("cdc_ether: Improve ZTE MF823/831/910 handling") Reported-by:

When packet_set_ring creates a ring buffer it will initialize a struct timer_list if the packet version is TPACKET_V3. This value can then be raced by a different thread calling setsockopt to set the version to TPACKET_V1 before packet_set_ring has finished. This leads to a use-after-free on a function pointer in the struct timer_list when the socket is closed as the previously initialized timer will not be deleted. The bug is fixed by taking lock_sock(sk) in packet_setsockopt when changing the packet version while also taking the lock at the start of packet_set_ring.

The driver already uses its private lock for synchronization between xmit and xmit completion handler making the additional use of the xmit_lock unnecessary. Furthermore the driver does not set NETIF_F_LLTX resulting in xmit to be called with the xmit_lock held and then taking the private lock while xmit completion handler does the reverse, first take the private lock, then the xmit_lock. Fix these issues by not taking the xmit_lock in the tx completion handler. Signed-off-by:

With binutils-2.26 and before, a weak missing symbol was kept during the final link, and a missing CRC for an export would lead to that CRC being treated as zero implicitly. With binutils-2.27, the crc symbol gets dropped, and any module trying to use it will fail to load. This sets the weak CRC symbol to zero explicitly, making it defined in vmlinux, which in turn lets us load the modules referring to that CRC. The comment above the __CRC_SYMBOL macro suggests that this was always the intention, although it also seems that all symbols defined in C have a correct CRC these days, and only the exports that are now done in assembly need this.

The core and the cluster sleep state entry latencies can't be same as cluster sleep involves more work compared to core level e.g. shared cache maintenance. Experiments have shown on an average about 100us more latency for the cluster sleep state compared to the core level sleep. This patch fixes the entry latency for the cluster sleep state.

Johan Hovold says: ==================== net: stmmac: fix probe error handling and phydev leaks This series fixes a number of issues with the stmmac-driver probe error handling, which for example left clocks enabled after probe failures. The final patch fixes a failure to deregister and free any fixed-link PHYs that were registered during probe on probe errors and on driver unbind. It also fixes a related of-node leak on late probe errors. This series depends on the of_phy_deregister_fixed_link() helper that was just merged to net. As mentioned earlier, one staging driver also suffers from a similar leak and can be fixed up once the above mentioned helper hits mainline. Note that these patches have only been compile tested. ==================== Acked-by:

Make sure to deregister and free any fixed-link phy registered during probe on probe errors and on driver unbind by adding a new glue helper function. Drop the of-node reference taken in the same path also on late probe errors (and not just on driver unbind) by moving the put from stmmac_dvr_remove() to the new helper.

In the case of IPIP and SIT tunnel frames the outer transport header offset is actually set to the same offset as the inner transport header. This results in the lco_csum call not doing any checksum computation over the inner IPv4/v6 header data. In order to account for that I am updating the code so that we determine the location to start the checksum ourselves based on the location of the IPv4 header and the length.
