The commit 8724ecb0 ("Input: allow matching device IDs on property bits") started using property bits when generating module aliases for input handlers, but did not adjust the generation of MODALIAS attribute on input device uevents, breaking automatic module loading. Given that no handler currently uses property bits in their module tables, let's revert this part of the commit for now.

This is the possible reason for different hard to reproduce problems on my ARMv7-SMP test system. The symptoms are in recent kernels imprecise external aborts, and in older kernels various kinds of network stalls and unexpected page allocation failures. My testing indicates that the trouble started between v4.5 and v4.6 and prevails up to v4.14. Using the dirty_tx before acquiring the spin lock is clearly wrong and was first introduced with v4.6.

When syzkaller team brought us a C repro for the crash [1] that had been reported many times in the past, I finally could find the root cause. If FlowLabel info is merged by fl6_merge_options(), we leave part of the opt_space storage provided by udp/raw/l2tp with random value in opt_space.tot_len, unless a control message was provided at sendmsg() time. Then ip6_setup_cork() would use this random value to perform a kzalloc() call. Undefined behavior and crashes. Fix is to properly set tot_len in fl6_merge_options() At the same time, we can also avoid consuming memory and cpu cycles to clear it, if every option is copied via a kmemdup(). This is the change in ip6_setup_cork().

If an Ethernet PHY is initialized before the interrupt controller it is connected to, a message like the following is printed: irq: no irq domain found for /interrupt-controller@e61c0000 ! However, the actual error is ignored, leading to a non-functional (POLL) PHY interrupt later: Micrel KSZ8041RNLI ee700000.ethernet-ffffffff:01: attached PHY driver [Micrel KSZ8041RNLI] (mii_bus:phy_addr=ee700000.ethernet-ffffffff:01, irq=POLL) Depending on whether the PHY driver will fall back to polling, Ethernet may or may not work. To fix this: 1. Switch of_mdiobus_register_phy() from irq_of_parse_and_map() to of_irq_get(). Unlike the former, the latter returns -EPROBE_DEFER if the interrupt controller is not yet available, so this condition can be detected. Other errors are handled the same as before, i.e. use the passed mdio->irq[addr] as interrupt. 2. Propagate and handle errors from of_mdiobus_register_phy() and of_mdiobus_register_device().

Jiri Pirko says: ==================== mlxsw: spectrum: Configure TTL of "inherit" for offloaded tunnels Petr says: Currently mlxsw only offloads tunnels that are configured with TTL of "inherit" (which is the default). However, Spectrum defaults to 255 and the driver neglects to change the configuration. Thus the tunnel packets from offloaded tunnels always have TTL of 255, even though tunnels with explicit TTL of 255 are never actually offloaded. To fix this, introduce support for TIGCR, the register that keeps the related bits of global tunnel configuration, and use it on first offload to properly configure inheritance of TTL of tunnel packets from overlay packets. ==================== Signed-off-by: NDavid S.

Syzkaller hits WARN_ON(sk->sk_wmem_queued) in sk_stream_kill_queues after triggering an EFAULT in __zerocopy_sg_from_iter. On this error, skb_zerocopy_stream_iter resets the skb to its state before the operation with __pskb_trim. It cannot kfree_skb like datagram callers, as the skb may have data from a previous send call. __pskb_trim calls skb_condense for unowned skbs, which adjusts their truesize. These tcp skbuffs are owned and their truesize must add up to sk_wmem_queued. But they match because their skb->sk is NULL until tcp_transmit_skb. Temporarily set skb->sk when calling __pskb_trim to signal that the skbuffs are owned and avoid the skb_condense path.

Daniel Borkmann says: ==================== Two BPF fixes for range marking The set contains two fixes for direct packet access range markings and test cases for all direct packet access patterns that the verifier matches on. They are targeted for net tree, note that once net gets merged into net-next, there will be a minor merge conflict due to signature change of the function find_good_pkt_pointers() as well as data_meta patterns present in net-next tree. You can just add bool false to the data_meta patterns and I will follow-up with properly converting the patterns for data_meta in a similar way. ==================== Signed-off-by: NDavid S.

Lets add test cases to cover really all possible direct packet access tests for good/bad access cases so we keep tracking them.

Alexander had a test program with direct packet access, where the access test was in the form of data + X > data_end. In an unrelated change to the program LLVM decided to swap the branches and emitted code for the test in form of data + X <= data_end. We hadn't seen these being generated previously, thus verifier would reject the program. Therefore, fix up the verifier to detect all test cases, so we don't run into such issues in the future.

During review I noticed that the current logic for direct packet access marking in check_cond_jmp_op() has an off by one for the upper right range border when marking in find_good_pkt_pointers() with BPF_JLT and BPF_JLE. It's not really harmful given access up to pkt_end is always safe, but we should nevertheless correct the range marking before it becomes ABI. If pkt_data' denotes a pkt_data derived pointer (pkt_data + X), then for pkt_data' < pkt_end in the true branch as well as for pkt_end <= pkt_data' in the false branch we mark the range with X although it should really be X - 1 in these cases. For example, X could be pkt_end - pkt_data, then when testing for pkt_data' < pkt_end the verifier simulation cannot deduce that a byte load of pkt_data' - 1 would succeed in this branch.

An integer overflow is possible in dev_map_bitmap_size() when calculating the BITS_TO_LONG logic which becomes, after macro replacement, (((n) + (d) - 1)/ (d)) where 'n' is a __u32 and 'd' is (8 * sizeof(long)). To avoid overflow cast to u64 before arithmetic.

The recent rework of the cpu hotplug internals changed the usage of the per cpu state->node field, but missed to clean it up after usage. So subsequent hotplug operations use the stale pointer from a previous operation and hand it into the callback functions. The callbacks then dereference a pointer which either belongs to a different facility or points to freed and potentially reused memory. In either case data corruption and crashes are the obvious consequence. Reset the node and the last pointers in the per cpu state to NULL after the operation which set them has completed.
