* ipv6: Change "final" protocol processing for encapsulationTom Herbert2016-05-211-1/+14
| | | | | | | | | | | | | | | | | | | | | | When performing foo-over-UDP, UDP packets are processed by the encapsulation handler which returns another protocol to process. This may result in processing two (or more) protocols in the loop that are marked as INET6_PROTO_FINAL. The actions taken for hitting a final protocol, in particular the skb_postpull_rcsum can only be performed once. This patch set adds a check of a final protocol has been seen. The rules are: - If the final protocol has not been seen any protocol is processed (final and non-final). In the case of a final protocol, the final actions are taken (like the skb_postpull_rcsum) - If a final protocol has been seen (e.g. an encapsulating UDP header) then no further non-final protocols are allowed (e.g. extension headers). For more final protocols the final actions are not taken (e.g. skb_postpull_rcsum). Signed-off-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* ipv6: Fix nexthdr for reinjectionTom Herbert2016-05-211-3/+15
| | | | | | | | | | | | | | | In ip6_input_finish the nexthdr protocol is retrieved from the next header offset that is returned in the cb of the skb. This method does not work for UDP encapsulation that may not even have a concept of a nexthdr field (e.g. FOU). This patch checks for a final protocol (INET6_PROTO_FINAL) when a protocol handler returns > 0. If the protocol is not final then resubmission is performed on nhoff value. If the protocol is final then the nexthdr is taken to be the return value. Signed-off-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: define gso types for IPx over IPv4 and IPv6Tom Herbert2016-05-2119-50/+37Star
| | | | | | | | | | | | | | | | This patch defines two new GSO definitions SKB_GSO_IPXIP4 and SKB_GSO_IPXIP6 along with corresponding NETIF_F_GSO_IPXIP4 and NETIF_F_GSO_IPXIP6. These are used to described IP in IP tunnel and what the outer protocol is. The inner protocol can be deduced from other GSO types (e.g. SKB_GSO_TCPV4 and SKB_GSO_TCPV6). The GSO types of SKB_GSO_IPIP and SKB_GSO_SIT are removed (these are both instances of SKB_GSO_IPXIP4). SKB_GSO_IPXIP6 will be used when support for GSO with IP encapsulation over IPv6 is added.

* gso: Remove arbitrary checks for unsupported GSOTom Herbert2016-05-217-102/+1Star
| | | | | | | | | | | | | | In several gso_segment functions there are checks of gso_type against a seemingly arbitrary list of SKB_GSO_* flags. This seems like an attempt to identify unsupported GSO types, but since the stack is the one that set these GSO types in the first place this seems unnecessary to do. If a combination isn't valid in the first place that stack should not allow setting it. This is a code simplication especially for add new GSO types.

* xen-netback: only deinitialized hash if it was initializedPaul Durrant2016-05-201-2/+1Star
| | | | | | | | | | | | | | | | | | | | A domain with a frontend that does not implement a control ring has been seen to cause a crash during domain save. This was apparently because the call to xenvif_deinit_hash() in xenvif_disconnect_ctrl() is made regardless of whether a control ring was connected, and hence xenvif_hash_init() was called. This patch brings the call to xenvif_deinit_hash() in xenvif_disconnect_ctrl() inside the if clause that checks whether the control ring event channel was connected. This is sufficient to ensure it is only called if xenvif_init_hash() was called previously.

| | | | | | | | | | | | | | | | | | | | | When CONFIG_NET_CLS_ACT is disabled, we get a new warning in the mlx5 ethernet driver because the tc_for_each_action() loop never references the iterator: mellanox/mlx5/core/en_tc.c: In function 'mlx5e_stats_flower': mellanox/mlx5/core/en_tc.c:431:20: error: unused variable 'a' [-Werror=unused-variable] struct tc_action *a; This changes the dummy tc_for_each_action() macro by adding a cast to void, letting the compiler know that the variable is intentionally declared but not used here.

* phy: fix crash in fixed_phy_add()Rabin Vincent2016-05-201-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | Since e7f4dc3536a ("mdio: Move allocation of interrupts into core"), platforms which call fixed_phy_add() before fixed_mdio_bus_init() is called (for example, because the platform code and the fixed_phy driver use the same initcall level) crash in fixed_phy_add() since the ->mii_bus is not allocated. Also since e7f4dc3536a, these interrupts are initalized to polling by default. The few (old) platforms which directly use fixed_phy_add() from their platform code all pass PHY_POLL for the irq argument, so we can keep these platforms not crashing by simply not attempting to set the irq if PHY_POLL is passed. Also, even if problems have not been reported on more modern platforms which used fixed_phy_register() from drivers' probe functions, we return -EPROBE_DEFER if the MDIO bus is not yet registered so that the probe is retried later.

But the error handling of this function frees the already resized buffer for bcast_own when the allocation of the new bcast_own_sum buffer failed. This will lead to an invalid memory access when some code will try to access bcast_own. Instead the resized new bcast_own buffer has to be kept. This will not lead to problems because the size of the buffer was only increased and therefore no user of the buffer will try to access bytes outside of the new buffer.

It meants all the clock modules are available quite late in the boot sequence. So request for CPU clock by clk_get_sys() and clk_get_rate() to find c0_timer rate fails. To fix this use PIC32 specific early clock functions implemented for early console support.

Add a check for whether the toolchain supports the -mvirt option, similar to the MSA toolchain check, and implement the accessors using .word if not. Due to difficulty in converting compiler specified registers (e.g. "$3") to usable numbers (e.g. "3") in inline asm, we need to copy to/from a temporary register, namely the assembler temporary (at/$1), and specify guest CP0 registers numerically in the gc0 macros.

Unfortunately this means that a rebuild which tries to rerun genvdso to generate vdso*-image.c without also rebuilding vdso.so.dbg (for example if genvdso.c is modified) hits a build error like this: arch/mips/vdso/genvdso 'arch/mips/vdso/vdso.so.dbg' already contains a '.MIPS.abiflags' section This is fixed by reorganising the rules such that unmodified .so files have a .raw suffix, and these are copied in the same rule that runs genvdso on the copies. I.e. previously we had: cmd_vdsold: link objects -> vdso.so.dbg cmd_genvdso: strip vdso.so.dbg -> vdso.so run genvdso -> vdso-image.c and modify vdso.so.dbg and vdso.so in place Now we have: cmd_vdsold: link objects -> vdso.so.dbg.raw a new cmd_objcopy based strip rule (inspired by ARM): strip vdso.so.dbg.raw -> vdso.so.raw cmd_genvdso: copy vdso.so.dbg.raw -> vdso.so.dbg copy vdso.so.raw -> vdso.so run genvdso -> vdso-image.c and modify vdso.so.dbg and vdso.so in place Signed-off-by: James Hogan <james.hogan@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/13250/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
