When CONFIG_XFRM_SUB_POLICY=y, xfrm_dst stores a copy of the flowi for that dst. Unfortunately, the code that allocates and fills this copy doesn't care about what type of flowi (flowi, flowi4, flowi6) gets passed. In multiple code paths (from raw_sendmsg, from TCP when replying to a FIN, in vxlan, geneve, and gre), the flowi that gets passed to xfrm is actually an on-stack flowi4, so we end up reading stuff from the stack past the end of the flowi4 struct. Since xfrm_dst->origin isn't used anywhere following commit ca116922 ("xfrm: Eliminate "fl" and "pol" args to xfrm_bundle_ok()."), just get rid of it. xfrm_dst->partner isn't used either, so get rid of that too. Fixes: 9d6ec938 ("ipv4: Use flowi4 in public route lookup interfaces.") Signed-off-by:

Locally generated TCP packets are usually cloned, so we do skb_cow_data() on this packets. After that we need to reload the pointer to the esp header. On udpencap this header has an offset to skb_transport_header, so take this offset into account.

Nathan Fontenot says: ==================== ibmvnic: Updated reset handler and code fixes This set of patches multiple code fixes and a new rest handler for the ibmvnic driver. In order to implement the new reset handler for the ibmvnic driver resource initialization needed to be moved to its own routine, a state variable is introduced to replace the various is_* flags in the driver, and a new routine to handle the assorted reasons the driver can be reset. v4 updates: Patch 3/11: Corrected trailing whitespace Patch 7/11: Corrected trailing whitespace v3 updates: Patch 10/11: Correct patch subject line to be a description of the patch. v2 updates: Patch 11/11: Use __netif_subqueue_stopped() instead of netif_subqueue_stopped() to avoid possible use of an un-initialized skb variable. ==================== Signed-off-by:David S.

Nathan Fontenot authored
When closing the ibmvnic driver, most notably during the reset path, the tx pools need to be cleaned to ensure there are no hanging skbs that need to be free'ed. The need for this was found during debugging a loss of network traffic after handling a driver reset. The underlying cause was some skbs in the tx pool that were never free'ed. As a result the upper network layers never tried a re-send since it believed the driver still had the skb. Signed-off-by:

The ibmvnic driver has multiple handlers for resetting the driver depending on the reason the reset is needed (failover, lpm, fatal erors,...). All of the reset handlers do essentially the same thing, this patch moves this work to a common reset handler. By doing this we also allow the driver to better handle situations where we can get a reset while handling a reset. The updated reset handling works by adding a reset work item to the list of resets and then scheduling work to perform the reset. This step is necessary because we can receive a reset in interrupt context and we want to handle the reset out of interrupt context. Signed-off-by:

Pablo Neira Ayuso says: ==================== Netfilter/IPVS/OVS fixes for net The following patchset contains a rather large batch of Netfilter, IPVS and OVS fixes for your net tree. This includes fixes for ctnetlink, the userspace conntrack helper infrastructure, conntrack OVS support, ebtables DNAT target, several leaks in error path among other. More specifically, they are: 1) Fix reference count leak in the CT target error path, from Gao Feng. 2) Remove conntrack entry clashing with a matching expectation, patch from Jarno Rajahalme. 3) Fix bogus EEXIST when registering two different userspace helpers, from Liping Zhang. 4) Don't leak dummy elements in the new bitmap set type in nf_tables, from Liping Zhang. 5) Get rid of module autoload from conntrack update path in ctnetlink, we don't need autoload at this late stage and it is happening with rcu read lock held which is not good. From Liping Zhang. 6) Fix deadlock due to double-acquire of the expect_lock from conntrack update path, this fixes a bug that was introduced when the central spinlock got removed. Again from Liping Zhang. 7) Safe ct->status update from ctnetlink path, from Liping. The expect_lock protection that was selected when the central spinlock was removed was not really protecting anything at all. 8) Protect sequence adjustment under ct->lock. 9) Missing socket match with IPv6, from Peter Tirsek. 10) Adjust skb->pkt_type of DNAT'ed frames from ebtables, from Linus Luessing. 11) Don't give up on evaluating the expression on new entries added via dynset expression in nf_tables, from Liping Zhang. 12) Use skb_checksum() when mangling icmpv6 in IPv6 NAT as this deals with non-linear skbuffs. 13) Don't allow IPv6 service in IPVS if no IPv6 support is available, from Paolo Abeni. 14) Missing mutex release in error path of xt_find_table_lock(), from Dan Carpenter. 15) Update maintainers files, Netfilter section. Add Florian to the file, refer to nftables.org and change project status from Supported to Maintained. 16) Bail out on mismatching extensions in element updates in nf_tables. ==================== Signed-off-by: -

Small follow-up to d74a32ac ("xdp: use netlink extended ACK reporting") in order to let drivers all use the same NL_SET_ERR_MSG_MOD() helper macro for reporting. This also ensures that we consistently add the driver's prefix for dumping the report in user space to indicate that the error message is driver specific and not coming from core code. Furthermore, NL_SET_ERR_MSG_MOD() now reuses NL_SET_ERR_MSG() and thus makes all macros check the pointer as suggested. References: https://www.spinics.net/lists/netdev/msg433267.htmlSigned-off-by:

Andrey's reproducer program runs in a very tight loop, calling 'unshare -n' and then spawning 2 sets of 14 threads running random ioctl calls. The relevant networking sequence: 1. New network namespace created via unshare -n - ip6tnl0 device is created in down state 2. address added to ip6tnl0 - equivalent to ip -6 addr add dev ip6tnl0 fd00::bb/1 - DAD is started on the address and when it completes the host route is inserted into the FIB 3. ip6tnl0 is brought up - the new fixup_permanent_addr function restarts DAD on the address 4. exit namespace - teardown / cleanup sequence starts - once in a blue moon, lo teardown appears to happen BEFORE teardown of ip6tunl0 + down on 'lo' removes the host route from the FIB since the dst->dev for the route is loobback + host route added to rcu callback list * rcu callback has not run yet, so rt is NOT on the gc list so it has NOT been marked obsolete 5. in parallel to 4. worker_thread runs addrconf_dad_completed - DAD on the address on ip6tnl0 completes - calls ipv6_ifa_notify which inserts the host route All of that happens very quickly. The result is that a host route that has been deleted from the IPv6 FIB and added to the RCU list is re-inserted into the FIB. The exit namespace eventually gets to cleaning up ip6tnl0 which removes the host route from the FIB again, calls the rcu function for cleanup -- and triggers the double rcu trace. The root cause is duplicate DAD on the address -- steps 2 and 3. Arguably, DAD should not be started in step 2. The interface is in the down state, so it can not really send out requests for the address which makes starting DAD pointless. Since the second DAD was introduced by a recent change, seems appropriate to use it for the Fixes tag and have the fixup function only start DAD for addresses in the PREDAD state which occurs in addrconf_ifdown if the address is retained. Big thanks to Andrey for isolating a reliable reproducer for this problem.

Jesper Dangaard Brouer says: ==================== Improve bpf ELF-loader under samples/bpf This series improves and fixes bpf ELF loader and programs under samples/bpf. The bpf_load.c created some hard to debug issues when the struct (bpf_map_def) used in the ELF maps section format changed in commit fb30d4b7 ("bpf: Add tests for map-in-map"). This was hotfixed in commit 409526bea3c3 ("samples/bpf: bpf_load.c detect and abort if ELF maps section size is wrong") by detecting the issue and aborting the program. In most situations the bpf-loader should be able to handle these kind of changes to the struct size. This patch series aim to do proper backward and forward compabilility handling when loading ELF files. This series also adjust the callback that was introduced in commit 9fd63d05 ("bpf: Allow bpf sample programs (*_user.c) to change bpf_map_def") to use the new bpf_map_data structure, before more users start to use this callback. Hoping these changes can make the merge window, as above mentioned commits have not been merged yet, and it would be good to avoid users hitting these issues. ==================== Acked-by:

This patch extends capabilities of commit 9fd63d05 ("bpf: Allow bpf sample programs (*_user.c) to change bpf_map_def"). Give fixup callback access to struct bpf_map_data, instead of only stuct bpf_map_def. This add flexibility to allow userspace to reassign the map file descriptor. This is very useful when wanting to share maps between several bpf programs. Signed-off-by:

This patch does proper parsing of the ELF "maps" section, in-order to be both backwards and forwards compatible with changes to the map definition struct bpf_map_def, which gets compiled into the ELF file. The assumption is that new features with value zero, means that they are not in-use. For backward compatibility where loading an ELF file with a smaller struct bpf_map_def, only copy objects ELF size, leaving rest of loaders struct zero. For forward compatibility where ELF file have a larger struct bpf_map_def, only copy loaders own struct size and verify that rest of the larger struct is zero, assuming this means the newer feature was not activated, thus it should be safe for this older loader to load this newer ELF file.

This extends the nature of the types of patches that can be applied by live patching infrastructure. The code stems from the design proposal made [1] back in November 2014. It's a hybrid of SUSE's kGraft and RH's kpatch, combining advantages of both: it uses kGraft's per-task consistency and syscall barrier switching combined with kpatch's stack trace switching. There are also a number of fallback options which make it quite flexible.

Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v4.12 cycle. The extra week before the merge window actually resulted in some of the type of fixes that usually arrive after the merge window already starting to trickle in from eager developers using -next, I'm impressed. I have recruited a Samsung subsubsystem maintainer (Krzysztof) to deal with the onset of Samsung patches. It works great. Apart from that it is a boring round, just incremental updates and fixes all over the place, no serious core changes or anything exciting like that. The most pleasing to see is Julia Cartwrights work to audit the irqchip-providing drivers for realtime locking compliance. It's one of those "I should really get around to looking into that" things that have been on my TODO list since forever. Summary: Core changes: - add bi-directional and output-enable pin configurations to the generic bindings and generic pin controlling core. New drivers or subdrivers: - Armada 37xx SoC pin controller and GPIO support. - Axis ARTPEC-6 SoC pin controller support. - AllWinner A64 R_PIO controller support, and opening up the AllWinner sunxi driver for ARM64 use. - Rockchip RK3328 support. - Renesas R-Car H3 ES2.0 support. - STM32F469 support in the STM32 driver. - Aspeed G4 and G5 pin controller support. Improvements: - a whole slew of realtime improvements to drivers implementing irqchips: BCM, AMD, SiRF, sunxi, rockchip. - switch meson driver to get the GPIO ranges from the device tree. - input schmitt trigger support on the Rockchip driver. - enable the sunxi (AllWinner) driver to also be used on ARM64 silicon. - name the Qualcomm QDF2xxx GPIO lines. - support GMMR GPIO regions on the Intel Cherryview. This fixes a serialization problem on these platforms. - pad retention support for the Samsung Exynos 5433. - handle suspend-to-ram in the AT91-pio4 driver. - pin configuration support in the Aspeed driver.

We try to make this function more readable by improving variable names and comments, using more stack variables, and doing some smaller changes to the logics. We also rename the function to make it consistent with naming conventions used elsewhere in the code. Reviewed-by:
