We cannot reliable calculate packet size on MSG_MORE corked sockets and thus cannot decide if they are going to be fragmented later on, so better not use CHECKSUM_PARTIAL in the first place.

rbd requires stable pages, as it performs a crc of the page data before they are send to the OSDs. But since kernel 3.9 (patch 1d1d1a76 "mm: only enforce stable page writes if the backing device requires it") it is not assumed anymore that block devices require stable pages. This patch sets the necessary flag to get stable pages back for rbd. In a ceph installation that provides multiple ext4 formatted rbd devices "bad crc" messages appeared regularly (ca 1 message every 1-2 minutes on every OSD that provided the data for the rbd) in the OSD-logs before this patch. After this patch this messages are pretty much gone (only ca 1-2 / month / OSD).

Steffen Klassert says: ==================== pull request (net-next): ipsec-next 2015-10-30 1) The flow cache is limited by the flow cache limit which depends on the number of cpus and the xfrm garbage collector threshold which is independent of the number of cpus. This leads to the fact that on systems with more than 16 cpus we hit the xfrm garbage collector limit and refuse new allocations, so new flows are dropped. On systems with 16 or less cpus, we hit the flowcache limit. In this case, we shrink the flow cache instead of refusing new flows. We increase the xfrm garbage collector threshold to INT_MAX to get the same behaviour, independent of the number of cpus. 2) Fix some unaligned accesses on sparc systems. From Sowmini Varadhan. 3) Fix some header checks in _decode_session4. We may call pskb_may_pull with a negative value converted to unsigened int from pskb_may_pull. This can lead to incorrect policy lookups. We fix this by a check of the data pointer position before we call pskb_may_pull. 4) Reload skb header pointers after calling pskb_may_pull in _decode_session4 as this may change the pointers into the packet. 5) Add a missing statistic counter on inner mode errors. Please pull or let me know if there are problems. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

It's a bit bigger than usual, the 3 main culprits being: - A new driver for Intel's Fields Peak NCI chipset. In order to support this chipset we had to export a few NCI routines and extend the driver NCI ops to not only support proprietary commands but also core ones. - Support for vendor commands for both STM drivers, st-nci and st21nfca. Those vendor commands allow to run factory tests through the NFC netlink interface. - New i2c and SPI support for the Marvell driver, together with firmware download support for this driver's core. Besides that we also have: - A few file renames in the STM drivers, to keep the naming consistent between drivers. - Some improvements and fixes on the NCI HCI layer, mostly to properly reach a secure element over a legacy HCI link. - A few fixes for the s3fwrn5 and trf7970a drivers. ==================== Signed-off-by: NDavid S.

Problem Description: We can add fdbs pointing to the bridge with NULL ->dst but that has a few race conditions because br_fdb_insert() is used which first creates the fdb and then, after the fdb has been published/linked, sets "is_local" to 1 and in that time frame if a packet arrives for that fdb it may see it as non-local and either do a NULL ptr dereference in br_forward() or attach the fdb to the port where it arrived, and later br_fdb_insert() will make it local thus getting a wrong fdb entry. Call chain br_handle_frame_finish() -> br_forward(): But in br_handle_frame_finish() in order to call br_forward() the dst should not be local i.e. skb != NULL, whenever the dst is found to be local skb is set to NULL so we can't forward it, and here comes the problem since it's running only with RCU when forwarding packets it can see the entry before "is_local" is set to 1 and actually try to dereference NULL. The main issue is that if someone sends a packet to the switch while it's adding the entry which points to the bridge device, it may dereference NULL ptr. This is needed now after we can add fdbs pointing to the bridge. This poses a problem for br_fdb_update() as well, while someone's adding a bridge fdb, but before it has is_local == 1, it might get moved to a port if it comes as a source mac and then it may get its "is_local" set to 1 This patch changes fdb_create to take is_local and is_static as arguments to set these values in the fdb entry before it is added to the hash. Also adds null check for port in br_forward.

The current arm64 Image relocation code in the UEFI stub assumes that the dram_base argument it receives is always a multiple of 2 MB. In reality, it is simply the lowest start address of all RAM entries in the UEFI memory map, which means it could be any multiple of 4 KB. Since the arm64 kernel Image needs to reside TEXT_OFFSET bytes beyond a 2 MB aligned base, or it will fail to boot, make sure we round dram_base to 2 MB before using it to calculate the relocation address.

Raw sockets with hdrincl enabled can insert ipv6 extension headers right into the data stream. In case we need to fragment those packets, we reparse the options header to find the place where we can insert the fragment header. If the extension headers exceed the link's MTU we actually cannot make progress in such a case. Instead of ending up in broken arithmetic or rounding towards 0 and entering an endless loop in ip6_fragment, just prevent those cases by aborting early and signal -EMSGSIZE to user space. This is the second version of the patch which doesn't use the overflow_usub function, which got reverted for now.
