2018-09-18iavf: rename functions and structs to new nameJesse Brandeburg
This basically begins the internal portion of the rename of i40evf to iavf, by renaming many of the functions, structs, variables and defines. Most of the changes were made mechanically, which introduces some alignment issues.

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/ipv6: do not copy dst flags on rt initPeter Oskolkov
DST_NOCOUNT in dst_entry::flags tracks whether the entry counts toward route cache size (net->ipv6.sysctl.ip6_rt_max_size). If the flag is NOT set, dst_ops::pcpuc_entries counter is incremented in dist_init() and decremented in dst_destroy(). This flag is tied to allocation/deallocation of dst_entry and should not be copied from another dst/route. Otherwise it can happen that dst_ops::pcpuc_entries counter grows until no new routes can be allocated because the counter reached ip6_rt_max_size due to DST_NOCOUNT not set and thus no counter decrements on gc-ed routes.

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.

2018-09-17qmi_wwan: set DTR for modems in forced USB2 modeBjørn Mork
Recent firmware revisions have added the ability to force these modems to USB2 mode, hiding their SuperSpeed capabilities from the host. The driver has been using the SuperSpeed capability, as shown by the bcdUSB field of the device descriptor, to detect the need to enable the DTR quirk. This method fails when the modems are forced to USB2 mode by the modem firmware. Fix by unconditionally enabling the DTR quirk for the affected device IDs.

Hans de Goede says: ==================== r8169 (x86) clk fixes to fix S0ix not being reached This series adds code to the r8169 ethernet driver to get and enable an external clock if present, avoiding the need for a hack in the clk-pmc-atom driver where that clock was left on continuesly causing x86 some devices to not reach deep power saving states (S0ix) when suspended causing to them to quickly drain their battery while suspended. The 3 commits in this series need to be merged in order to avoid regressions while bisecting. The clk-pmc-atom driver does not see much changes (it was last touched over a year ago). So the clk maintainers have agreed with merging all 3 patches through the net tree. All 3 patches have Stephen Boyd's Acked-by for this purpose.

2018-09-17clk: x86: Stop marking clocks as CLK_IS_CRITICALHans de Goede
Commit d31fd43c0f9a ("clk: x86: Do not gate clocks enabled by the firmware"), which added the code to mark clocks as CLK_IS_CRITICAL, causes all unclaimed PMC clocks on Cherry Trail devices to be on all the time, resulting on the device not being able to reach S0i3 when suspended. The reason for this commit is that on some Bay Trail / Cherry Trail devices the r8169 ethernet controller uses pmc_plt_clk_4. Now that the clk-pmc-atom driver exports an "ether_clk" alias for pmc_plt_clk_4 and the r8169 driver has been modified to get and enable this clock (if present) the marking of the clocks as CLK_IS_CRITICAL is no longer necessary. This commit removes the CLK_IS_CRITICAL marking, fixing Cherry Trail devices not being able to reach S0i3 greatly decreasing their battery drain when suspended.

2018-09-17r8169: Get and enable optional ether_clk clockHans de Goede
On some boards a platform clock is used as clock for the r8169 chip, this commit adds support for getting and enabling this clock (assuming it has an "ether_clk" alias set on it). This is related to commit d31fd43c0f9a ("clk: x86: Do not gate clocks enabled by the firmware") which is a previous attempt to fix this for some x86 boards, but this causes all Cherry Trail SoC using boards to not reach there lowest power states when suspending. This commit (together with an atom-pmc-clk driver commit adding the alias) fixes things properly by making the r8169 get the clock and enable it when it needs it.

2018-09-17clk: x86: add "ether_clk" alias for Bay Trail / Cherry TrailHans de Goede
Commit d31fd43c0f9a ("clk: x86: Do not gate clocks enabled by the firmware") causes all unclaimed PMC clocks on Cherry Trail devices to be on all the time, resulting on the device not being able to reach S0i2 or S0i3 when suspended. The reason for this commit is that on some Bay Trail / Cherry Trail devices the ethernet controller uses pmc_plt_clk_4. This commit adds an "ether_clk" alias, so that the relevant ethernet drivers can try to (optionally) use this, without needing X86 specific code / hacks, thus fixing ethernet on these devices without breaking S0i3 support. This commit uses clkdev_hw_create() to create the alias, mirroring the code for the already existing "mclk" alias for pmc_plt_clk_3.

2018-09-17kcm: remove any offset before parsing messagesDominique Martinet
The current code assumes kcm users know they need to look for the strparser offset within their bpf program, which is not documented anywhere and examples laying around do not do. The actual recv function does handle the offset well, so we can create a temporary clone of the skb and pull that one up as required for parsing. The pull itself has a cost if we are pulling beyond the head data, measured to 2-3% latency in a noisy VM with a local client stressing that path. The clone's impact seemed too small to measure. This bug can be exhibited easily by implementing a "trivial" kcm parser taking the first bytes as size, and on the client sending at least two such packets in a single write(). Note that bpf sockmap has the same problem, both for parse and for recv, so it would pulling twice or a real pull within the strparser logic if anyone cares about that.

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.

The function rds_inc_init is in recv process. To use memset can optimize the function rds_inc_init. The test result: Before: 1) + 24.950 us | rds_inc_init [rds](); After: 1) + 10.990 us | rds_inc_init [rds](); Acked-by: Santosh Shilimkar <santosh.shilimkar@oracle.com> Signed-off-by: Zhu Yanjun <yanjun.zhu@oracle.com> Signed-off-by: David S.

2018-09-17selftests/tls: Add MSG_WAITALL in recv() syscallVakul Garg
A number of tls selftests rely upon recv() to return an exact number of data bytes. When tls record crypto is done using an async accelerator, it is possible that recv() returns lesser than expected number bytes. This leads to failure of many test cases. To fix it, MSG_WAITALL has been used in flags passed to recv() syscall. Signed-off-by: Vakul Garg <vakul.garg@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
