2018-06-01ipvs: add ipv6 support to ftpJulian Anastasov
Add support for FTP commands with extended format (RFC 2428): - FTP EPRT: IPv4 and IPv6, active mode, similar to PORT - FTP EPSV: IPv4 and IPv6, passive mode, similar to PASV. EPSV response usually contains only port but we allow real server to provide different address We restrict control and data connection to be from same address family. Allow the "(" and ")" to be optional in PASV response. Also, add ipvsh argument to the pkt_in/pkt_out handlers to better access the payload after transport header.

2018-06-01xhci: Add quirk to zero 64bit registers on Renesas PCIe controllersMarc Zyngier
Some Renesas controllers get into a weird state if they are reset while programmed with 64bit addresses (they will preserve the top half of the address in internal, non visible registers). You end up with half the address coming from the kernel, and the other half coming from the firmware. Also, changing the programming leads to extra accesses even if the controller is supposed to be halted. The controller ends up with a fatal fault, and is then ripe for being properly reset. On the flip side, this is completely unsafe if the defvice isn't behind an IOMMU, so we have to make sure that this is the case. Can you say "broken"? This is an alternative method to the one introduced in 8466489ef5ba ("xhci: Reset Renesas uPD72020x USB controller for 32-bit DMA issue"), which will subsequently be removed.

2018-06-01ASoC: Intel: kbl: Move codec sysclk config to codec_init functionMac Chiang
On APL, commit fd0f237572ad ("ASoC: Intel: bxt: Move codec sysclk config to codec_init function") fixed an issue related to jack detection. The MCLK for DA7219 does not change in this platform, but is currently being configured everytime as part of the platform_clock event handler for DAPM. The upshot of this is that we have unnecessary calls to this function, and it also means that if a stream hasn't yet been started, DA7219 driver does not have the correct MCLK rates programmed and so the HP detection feature does not operate as expected. The same fix is needed on KBL. This patch rectifies this issue by moving the sysclk call to codec_init function so it's only called once at initialisation.

2018-06-01ASoC: simple-card: set cpu dai clk in hw_paramsDaniel Mack
The simple-card driver currently accepts a clock node in the cpu dai sub-node and only uses it as an alternative to the 'system-clock-frequency' property to get the current frequency. This patch adds another use of the passed clock node. If mclk-fs is specified, the clocks in cpu and codec dai sub-nodes will be set to the calculated rate (stream rate * mclk_fs) in hw_params. This allows platforms to pass tuneable clocks as phandle that will automatically be set to the right rates.

2018-06-01netfilter: nf_tables: fix chain dependency validationPablo Neira Ayuso
The following ruleset: add table ip filter add chain ip filter input { type filter hook input priority 4; } add chain ip filter ap add rule ip filter input jump ap add rule ip filter ap masquerade results in a panic, because the masquerade extension should be rejected from the filter chain. The existing validation is missing a chain dependency check when the rule is added to the non-base chain. This patch fixes the problem by walking down the rules from the basechains, searching for either immediate or lookup expressions, then jumping to non-base chains and again walking down the rules to perform the expression validation, so we make sure the full ruleset graph is validated. This is done only once from the commit phase, in case of problem, we abort the transaction and perform fine grain validation for error reporting. This patch requires 003087911af2 ("netfilter: nfnetlink: allow commit to fail") to achieve this behaviour. This patch also adds a cleanup callback to nfnl batch interface to reset the validate state from the exit path. As a result of this patch, nf_tables_check_loops() doesn't use ->validate to check for loops, instead it just checks for immediate expressions.

2018-06-01ALSA: hda - Handle kzalloc() failure in snd_hda_attach_pcm_stream()Bo Chen
When 'kzalloc()' fails in 'snd_hda_attach_pcm_stream()', a new pcm instance is created without setting its operators via 'snd_pcm_set_ops()'. Following operations on the new pcm instance can trigger kernel null pointer dereferences and cause kernel oops. This bug was found with my work on building a gray-box fault-injection tool for linux-kernel-module binaries. A kernel null pointer dereference was confirmed from line 'substream->ops->open()' in function 'snd_pcm_open_substream()' in file 'sound/core/pcm_native.c'. This patch fixes the bug by calling 'snd_device_free()' in the error handling path of 'kzalloc()', which removes the new pcm instance from the snd card before returns with an error code.

2018-05-31ixgbe: fix parsing of TC actions for HW offloadOndřej Hlavatý
The previous code was optimistic, accepting the offload of whole action chain when there was a single known action (drop/redirect). This results in offloading a rule which should not be offloaded, because its behavior cannot be reproduced in the hardware. For example: $ tc filter add dev eno1 parent ffff: protocol ip \ u32 ht 800: order 1 match tcp src 42 FFFF \ action mirred egress mirror dev enp1s16 pipe \ drop The controller is unable to mirror the packet to a VF, but still offloads the rule by dropping the packet. Change the approach of the function to a pessimistic one, rejecting the chain when an unknown action is found. This is better suited for future extensions. Note that both recognized actions always return TC_ACT_SHOT, therefore it is safe to ignore actions behind them.

2018-05-31rtnetlink: Remove VLA usageKees Cook
In the quest to remove all stack VLA usage from the kernel[1], this allocates the maximum size expected for all possible types and adds sanity-checks at both registration and usage to make sure nothing gets out of sync. This matches the proposed VLA solution for nfnetlink[2]. The values chosen here were based on finding assignments for .maxtype and .slave_maxtype and manually counting the enums: slave_maxtype (max 33): IFLA_BRPORT_MAX 33 IFLA_BOND_SLAVE_MAX 9 maxtype (max 45): IFLA_BOND_MAX 28 IFLA_BR_MAX 45 __IFLA_CAIF_HSI_MAX 8 IFLA_CAIF_MAX 4 IFLA_CAN_MAX 16 IFLA_GENEVE_MAX 12 IFLA_GRE_MAX 25 IFLA_GTP_MAX 5 IFLA_HSR_MAX 7 IFLA_IPOIB_MAX 4 IFLA_IPTUN_MAX 21 IFLA_IPVLAN_MAX 3 IFLA_MACSEC_MAX 15 IFLA_MACVLAN_MAX 7 IFLA_PPP_MAX 2 __IFLA_RMNET_MAX 4 IFLA_VLAN_MAX 6 IFLA_VRF_MAX 2 IFLA_VTI_MAX 7 IFLA_VXLAN_MAX 28 VETH_INFO_MAX 2 VXCAN_INFO_MAX 2 This additionally changes maxtype and slave_maxtype fields to unsigned, since they're only ever using positive values.

2018-06-01kbuild: add machine size to CHECKFLAGSLuc Van Oostenryck
By default, sparse assumes a 64bit machine when compiled on x86-64 and 32bit when compiled on anything else. This can of course create all sort of problems for the other archs, like issuing false warnings ('shift too big (32) for type unsigned long'), or worse, failing to emit legitimate warnings. Fix this by adding the -m32/-m64 flag, depending on CONFIG_64BIT, to CHECKFLAGS in the main Makefile (and so for all archs). Also, remove the now unneeded -m32/-m64 in arch specific Makefiles.

2018-05-31compiler.h: enable builtin overflow checkers and add fallback codeRasmus Villemoes
This adds wrappers for the __builtin overflow checkers present in gcc 5.1+ as well as fallback implementations for earlier compilers. It's not that easy to implement the fully generic __builtin_X_overflow(T1 a, T2 b, T3 *d) in macros, so the fallback code assumes that T1, T2 and T3 are the same. We obviously don't want the wrappers to have different semantics depending on $GCC_VERSION, so we also insist on that even when using the builtins. There are a few problems with the 'a+b < a' idiom for checking for overflow: For signed types, it relies on undefined behaviour and is not actually complete (it doesn't check underflow; e.g. INT_MIN+INT_MIN == 0 isn't caught). Due to type promotion it is wrong for all types (signed and unsigned) narrower than int. Similarly, when a and b does not have the same type, there are subtle cases like u32 a; if (a + sizeof(foo) < a) return -EOVERFLOW; a += sizeof(foo); where the test is always false on 64 bit platforms. Add to that that it is not always possible to determine the types involved at a glance. The new overflow.h is somewhat bulky, but that's mostly a result of trying to be type-generic, complete (e.g. catching not only overflow but also signed underflow) and not relying on undefined behaviour. Linus is of course right [1] that for unsigned subtraction a-b, the right way to check for overflow (underflow) is "b > a" and not "__builtin_sub_overflow(a, b, &d)", but that's just one out of six cases covered here, and included mostly for completeness. So is it worth it? I think it is, if nothing else for the documentation value of seeing if (check_add_overflow(a, b, &d)) return -EGOAWAY; do_stuff_with(d); instead of the open-coded (and possibly wrong and/or incomplete and/or UBsan-tickling) if (a+b < a) return -EGOAWAY; do_stuff_with(a+b); While gcc does recognize the 'a+b < a' idiom for testing unsigned add overflow, it doesn't do nearly as good for unsigned multiplication (there's also no single well-established idiom). So using check_mul_overflow in kcalloc and friends may also make gcc generate slightly better code.
