2018-09-18iavf: rename functions and structs to new nameJesse Brandeburg

2018-09-18intel-ethernet: rename i40evf to iavfJesse Brandeburg
Rename the Intel Ethernet Adaptive Virtual Function driver (i40evf) to a new name (iavf) that is more consistent with the ongoing maintenance of the driver as the universal VF driver for multiple product lines. This first patch fixes up the directory names and the .ko name, intentionally ignoring the function names inside the driver for now. Basically this is the simplest patch that gets the rename done and will be followed by other patches that rename the internal functions. This patch also addresses a couple of string/name issues and updates the Copyright year. Also, made sure to add a MODULE_ALIAS to the old name.

2018-09-17net/ipv4: defensive cipso option parsingStefan Nuernberger
commit 40413955ee26 ("Cipso: cipso_v4_optptr enter infinite loop") fixed a possible infinite loop in the IP option parsing of CIPSO. The fix assumes that ip_options_compile filtered out all zero length options and that no other one-byte options beside IPOPT_END and IPOPT_NOOP exist. While this assumption currently holds true, add explicit checks for zero length and invalid length options to be safe for the future. Even though ip_options_compile should have validated the options, the introduction of new one-byte options can still confuse this code without the additional checks.

Julian Wiedmann says: ==================== s390/qeth: updates 2018-09-17 please apply the following patchset to net-next. This brings more restructuring of qeth's transmit code (eliminating its last usage of skb_realloc_headroom()), and the usual mix of minor improvements & cleanups. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-17s390/qeth: reduce 0-initializing when building IPA cmdsJulian Wiedmann
qeth_get_ipacmd_buffer() obtains its buffers for building IPA cmds from __qeth_get_buffer(), where they are fully cleared. So get rid of all the additional zero-ing in various other places. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-17s390/qeth: fine-tune spinlocksJulian Wiedmann
For quite a lot of code paths it's obvious that they will never run in IRQ context. So replace their spin_lock_irqsave() calls with spin_lock_irq(). While at it, get rid of the redundant card pointer in struct qeth_reply that was used by qeth_send_control_data() to access the card's lock.

2018-09-17s390/qeth: invoke softirqs after napi_schedule()Julian Wiedmann
Calling napi_schedule() from process context does not ensure that the NET_RX softirq is run in a timely fashion. So trigger it manually. This is no big issue with current code. A call to ndo_open() is usually followed by a ndo_set_rx_mode() call, and for qeth this contains a spin_unlock_bh(). Except for OSN, where qeth_l2_set_rx_mode() bails out early. Nevertheless it's best to not depend on this behaviour, and just fix the issue at its source like all other drivers do. For instance see commit 83a0c6e58901 ("i40e: Invoke softirqs after napi_reschedule").

2018-09-17s390/qeth: uninstall IRQ handler on device removalJulian Wiedmann
When setting up, qeth installs its IRQ handler on the ccw devices. But the IRQ handler is not cleared on removal - so even after qeth yields control of the ccw devices, spurious interrupts would still be presented to us. Make (de-)installation of the IRQ handler part of the ccw channel setup/removal helpers, and while at it also add the appropriate locking. Shift around qeth_setup_channel() to avoid a forward declaration for qeth_irq(). Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-09-17s390/qeth: prepare for copy-free TSO transmissionJulian Wiedmann
Add all the necessary TSO plumbing to the copy-less transmit path. This includes calculating the right length of required protocol headers, and always building a separate buffer element for the TSO headers. A follow-up patch will then switch TSO traffic over to this path. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-17s390/qeth: check size of required HW header cache objectJulian Wiedmann
When qeth_add_hw_header() falls back to the header cache, ensure that the requested length doesn't exceed the object size. For current usage this is a no-brainer, but TSO transmission will introduce protocol headers of varying length. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-17s390/qeth: fix up protocol headers earlyJulian Wiedmann
When qeth_add_hw_header() falls back to the HW header cache, it also copies over the necessary protocol headers. Thus any manipulation to the protocol headers needs to happen before adding the HW header. For current usage this doesn't matter, but it becomes relevant when moving TSO transmission over to the faster code path. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-09-17s390/qeth: run non-offload L3 traffic over common xmit pathJulian Wiedmann
L3 OSAs can only offload IPv4 traffic, use the common L2 transmit path for all other traffic. In particular there's no support for TX VLAN offload, so any such packet needs to be manually de-accelerated via ndo_features_check().

2018-09-17net: aquantia: memory corruption on jumbo framesFriedemann Gerold
This patch fixes skb_shared area, which will be corrupted upon reception of 4K jumbo packets. Originally build_skb usage purpose was to reuse page for skb to eliminate needs of extra fragments. But that logic does not take into account that skb_shared_info should be reserved at the end of skb data area. In case packet data consumes all the page (4K), skb_shinfo location overflows the page. As a consequence, __build_skb zeroed shinfo data above the allocated page, corrupting next page. The issue is rarely seen in real life because jumbo are normally larger than 4K and that causes another code path to trigger. But it 100% reproducible with simple scapy packet, like: sendp(IP(dst="192.168.100.3") / TCP(dport=443) \ / Raw(RandString(size=(4096-40))), iface="enp1s0") Fixes: 018423e90bee ("net: ethernet: aquantia: Add ring support code") Reported-by: Friedemann Gerold <f.gerold@b-c-s.de> Reported-by: Michael Rauch <michael@rauch.be> Signed-off-by: Friedemann Gerold <f.gerold@b-c-s.de> Tested-by: Nikita Danilov <nikita.danilov@aquantia.com> Signed-off-by: Igor Russkikh <igor.russkikh@aquantia.com> Signed-off-by: David S.

2018-09-17net: lantiq: lantiq_xrx200: Move clock prepare to probe functionHauke Mehrtens
The switch and the MAC are in one IP core and they use the same clock signal from the clock generation unit. Currently the clock architecture in the lantiq SoC code does not allow to easily share the same clocks, this has to be fixed by switching to the common clock framework. As a workaround the clock of the switch and MAC should be activated when the MAC gets probed and only disabled when the MAC gets removed. This way it is ensured that the clock is always enabled when the switch or MAC is used. The switch can not be used without the MAC. This fixes a data bus error when rebooting the system and deactivating the switch and mac and later accessing some registers in the cleanup while the clocks are disabled.
