2018-06-26dh key: fix rounding up KDF output lengthEric Biggers
Commit 383203eff718 ("dh key: get rid of stack allocated array") changed kdf_ctr() to assume that the length of key material to derive is a multiple of the digest size. The length was supposed to be rounded up accordingly. However, the round_up() macro was used which only gives the correct result on power-of-2 arguments, whereas not all hash algorithms have power-of-2 digest sizes. In some cases this resulted in a write past the end of the 'outbuf' buffer. Fix it by switching to roundup(), which works for non-power-of-2 inputs.

2018-06-26netfilter: nf_conncount: fix garbage collection confirm raceFlorian Westphal
Yi-Hung Wei and Justin Pettit found a race in the garbage collection scheme used by nf_conncount. When doing list walk, we lookup the tuple in the conntrack table. If the lookup fails we remove this tuple from our list because the conntrack entry is gone. This is the common cause, but turns out its not the only one. The list entry could have been created just before by another cpu, i.e. the conntrack entry might not yet have been inserted into the global hash. The avoid this, we introduce a timestamp and the owning cpu. If the entry appears to be stale, evict only if: 1. The current cpu is the one that added the entry, or, 2. The timestamp is older than two jiffies The second constraint allows GC to be taken over by other cpu too (e.g. because a cpu was offlined or napi got moved to another cpu). We can't pretend the 'doubtful' entry wasn't in our list. Instead, when we don't find an entry indicate via IS_ERR that entry was removed ('did not exist' or withheld ('might-be-unconfirmed'). This most likely also fixes a xt_connlimit imbalance earlier reported by Dmitry Andrianov.

2018-06-26Merge branch 'net-sched-support-replay-of-filter-offload-when-binding-to-block'David S. Miller
Jakub Kicinski says: ==================== net: sched: support replay of filter offload when binding to block This series from John adds the ability to replay filter offload requests when new offload callback is being registered on a TC block. This is most likely to take place for shared blocks today, when a block which already has rules is bound to another interface. Prior to this patch set if any of the rules were offloaded the block bind would fail. A new tcf_proto_op is added to generate a filter-specific offload request. The new 'offload' op is supporting extack from day 0, hence we need to propagate extack to .ndo_setup_tc TC_BLOCK_BIND/TC_BLOCK_UNBIND and through tcf_block_cb_register() to tcf_block_playback_offloads(). The immediate use of this patch set is to simplify life of drivers which require duplicating rules when sharing blocks. Switch drivers (mlxsw) can bind ports to rule lists dynamically, NIC drivers generally don't have that ability and need the rules to be duplicated for each ingress they match on. In code terms this means that switch drivers don't register multiple callbacks for each port. NIC drivers do, and get a separate request and hance rule per-port, as if the block was not shared. The registration fails today, however, if some rules were already present. As John notes in description of patch 7, drivers which register multiple callbacks to shared blocks will likely need to flush the rules on block unbind. This set makes the core not only replay the the offload add requests but also offload remove requests when callback is unregistered. v2: - name parameters in patch 2; - use unsigned int instead of u32 for in_hw_coun; - improve extack message in patch 7. ==================== Signed-off-by: David S.

2018-06-26net: sched: call reoffload op on block callback regJohn Hurley
Call the reoffload tcf_proto_op on all tcf_proto nodes in all chains of a block when a callback tries to register to a block that already has offloaded rules. If all existing rules cannot be offloaded then the registration is rejected. This replaces the previous policy of rejecting such callback registration outright. On unregistration of a callback, the rules are flushed for that given cb. The implementation of block sharing in the NFP driver, for example, duplicates shared rules to all devs bound to a block. This meant that rules could still exist in hw even after a device is unbound from a block (assuming the block still remains active).

The main debug/discussion was on https://github.com/raspberrypi/linux/issues/2458 Initial symptoms were that VLANs were very unreliable. A couple of things were found: - firstly that the hardware timeout value set failed to take into account the VLAN tag, so a full MTU packet would be timed out. - second was that regular checksum failures were being reported. Disabling checksum offload confirmed that the checksums were valid, and further experimentation identified that it was only if the VLAN tags were being passed through to the kernel that there were issues. The hardware supports VLAN filtering and tag stripping, therefore those have been implemented (much of the work was already done), and the driver drops back to s/w checksums should the choice be made not to use the h/w VLAN stripping. ==================== Signed-off-by: David S.

2018-06-26PCI: shpchp: Manage SHPC unconditionally on non-ACPI systemsBjorn Helgaas
An SHPC can be operated either by platform firmware or by the OS. The OS uses a host bridge ACPI _OSC method to negotiate for control of SHPC. If firmware wants to prevent an OS from operating an SHPC, it must supply an _OSC method that declines to grant SHPC ownership to the OS. If acpi_pci_find_root() returns NULL, it means there's no ACPI host bridge device (PNP0A03 or PNP0A08) and hence no _OSC method, so the OS is always allowed to manage the SHPC. Fix a NULL pointer dereference when CONFIG_ACPI=y but the current hardware/firmware platform doesn't support ACPI. In that case, acpi_get_hp_hw_control_from_firmware() is implemented but acpi_pci_find_root() returns NULL.
