* tcp: fix SYNACK RTT estimation in Fast OpenYuchung Cheng2013-10-27
| | | | | | | | | | | | | tp->lsndtime may not always be the SYNACK timestamp if a passive Fast Open socket sends data before handshake completes. And if the remote acknowledges both the data and the SYNACK, the RTT sample is already taken in tcp_ack(), so no need to call tcp_update_ack_rtt() in tcp_synack_rtt_meas() aagain.

| * qlcnic: Do not read QLCNIC_FW_CAPABILITY_MORE_CAPS bit for 83xx adapterShahed Shaikh2013-10-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only 82xx adapter advertises QLCNIC_FW_CAPABILITY_MORE_CAPS bit. Reading this bit from 83xx adapter causes the driver to skip extra capabilities registers. Because of this, driver was not issuing qlcnic_fw_cmd_set_drv_version() for 83xx adapter. This bug was introduced in commit 8af3f33db05c6d0146ad14905145a5c923770856 ("qlcnic: Add support for 'set driver version' in 83XX").

* ipv6: ip6_dst_check needs to check for expired dst_entriesHannes Frederic Sowa2013-10-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On receiving a packet too big icmp error we check if our current cached dst_entry in the socket is still valid. This validation check did not care about the expiration of the (cached) route. The error path I traced down: The socket receives a packet too big mtu notification. It still has a valid dst_entry and thus issues the ip6_rt_pmtu_update on this dst_entry, setting RTF_EXPIRE and updates the dst.expiration value (which could fail because of not up-to-date expiration values, see previous patch). In some seldom cases we race with a) the ip6_fib gc or b) another routing lookup which would result in a recreation of the cached rt6_info from its parent non-cached rt6_info. While copying the rt6_info we reinitialize the metrics store by copying it over from the parent thus invalidating the just installed pmtu update (both dsts use the same key to the inetpeer storage). The dst_entry with the just invalidated metrics data would just get its RTF_EXPIRES flag cleared and would continue to stay valid for the socket. We should have not issued the pmtu update on the already expired dst_entry in the first placed. By checking the expiration on the dst entry and doing a relookup in case it is out of date we close the race because we would install a new rt6_info into the fib before we issue the pmtu update, thus closing this race. Not reliably updating the dst.expire value was fixed by the patch "ipv6: reset dst.expires value when clearing expire flag". Reported-by: Steinar H.

* ipv6: reset dst.expires value when clearing expire flagHannes Frederic Sowa2013-10-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On receiving a packet too big icmp error we update the expire value by calling rt6_update_expires. This function uses dst_set_expires which is implemented that it can only reduce the expiration value of the dst entry. If we insert new routing non-expiry information into the ipv6 fib where we already have a matching rt6_info we only clear the RTF_EXPIRES flag in rt6i_flags and leave the dst.expires value as is. When new mtu information arrives for that cached dst_entry we again call dst_set_expires. This time it won't update the dst.expire value because we left the dst.expire value intact from the last update. So dst_set_expires won't touch dst.expires. Fix this by resetting dst.expires when clearing the RTF_EXPIRE flag. dst_set_expires checks for a zero expiration and updates the dst.expires. In the past this (not updating dst.expires) was necessary because dst.expire was placed in a union with the dst_entry *from reference and rt6_clean_expires did assign NULL to it. This split happend in ecd9883724b78cc72ed92c98bcb1a46c764fff21 ("ipv6: fix race condition regarding dst->expires and dst->from"). Reported-by: Steinar H.

* netpoll: fix rx_hook() interface by passing the skbAntonio Quartulli2013-10-25
| | | | | | | | | | | | | | | | | | Right now skb->data is passed to rx_hook() even if the skb has not been linearised and without giving rx_hook() a way to linearise it. Change the rx_hook() interface and make it accept the skb and the offset to the UDP payload as arguments. rx_hook() is also renamed to rx_skb_hook() to ensure that out of the tree users notice the API change. In this way any rx_skb_hook() implementation can perform all the needed operations to properly (and safely) access the skb data.

* netconsole: fix multiple race conditionsNikolay Aleksandrov2013-10-25
| | | | | | | | | | | In every netconsole option that can be set through configfs there's a race when checking for nt->enabled since it can be modified at the same time.

* netconsole: fix NULL pointer dereferenceNikolay Aleksandrov2013-10-25
| | | | | | | | | | | | | | | | | | | We need to disable the netconsole (enabled = 0) before setting nt->np.dev to NULL because otherwise we might still have users after the netpoll_cleanup() since nt->enabled is set afterwards and we can have a message which will result in a NULL pointer dereference. It is very easy to hit dereferences all over the netpoll_send_udp function by running the following two loops in parallel: while [ 1 ]; do echo 1 > enabled; echo 0 > enabled; done; while [ 1 ]; do echo 00:11:22:33:44:55 > remote_mac; done; (the second loop is to generate messages, it can be done by anything) We're safe to set nt->np.dev = NULL and nt->enabled = 0 with the spinlock since it's required in the write_msg() function.

It can happen that the value stored on one CPU is smaller than the value stored on another CPU, although the order of the stores is the other way around. This can cause deltas of get_tod_clock() values to become negative when they should not be.

The get_tod_clock() function now uses the store-clock-extended (STCKE) instruction. get_tod_clock_fast() can be used if the fuzziness of store-clock-fast is acceptable e.g. for wait loops local to a CPU.

Following commit changes that, by introducing separate exynos4412_default_tmu_data structure. Since Exynos4412 was chronologically first, the corresponding name for TMU registers and default data was renamed. Additionally, new SOC_ARCH_EXYNOS4412 type has been defined. Moreover, the SOC_ARCH_EXYNOS name has been changed to SOC_ARCH_EXYNOS5250.

The resulting wrong test prevents thermal_zone_device_update() call, which calls handlers for situation when trip points are passed. Such behavior prevents thermal driver from proper reaction (when TMU interrupt is raised) in a situation when overheating is detected at TMU hardware. It turns out, that after exynos thermal subsystem redesign (at v3.12) this check is not needed, since it is not possible to register thermal zone without valid thermal device.

It precluded calling the driver's ioctls which require vfl_dir not to be equal to VFL_DIR_RX which is defined as 0 and uninitialized vfl_dir field is interpreted as such. In effect the test in the v4l_s_fmt function failed for the ioctls that expect is_tx to be false, which prevented the ioctl callbacks registered by the driver from being called.

Commit e15dab752d4c588544ccabdbe020a7cc092e23c8 introduced correct support for converting userpage to dma address, but unfortunately it broke the support for simple dma address = physical address for the case, when given physical frame has no struct page associated with it (this happens if one use for example dma_declare_coherent api or other reserved memory approach).

That register was likely set by firmware itself which means it could not contain reasonable values until firmware is up and running. Usually it just worked as some garbage value was returned accidentally but it appears that in some cases returned garbage value was 0x00 which was considered "firmware is up and running" by the driver and firmware loading was skipped leaving device to non-working state. Fix problem by removing unreliable check and let the driver keep count whether firmware is loaded or not.
