2016-12-21tcp: add a missing barrier in tcp_tasklet_func()Eric Dumazet1-0/+1
Madalin reported crashes happening in tcp_tasklet_func() on powerpc64 Before TSQ_QUEUED bit is cleared, we must ensure the changes done by list_del(&tp->tsq_node); are committed to memory, otherwise corruption might happen, as an other cpu could catch TSQ_QUEUED clearance too soon. We can notice that old kernels were immune to this bug, because TSQ_QUEUED was cleared after a bh_lock_sock(sk)/bh_unlock_sock(sk) section, but they could have missed a kick to write additional bytes, when NIC interrupts for a given flow are spread to multiple cpus. Affected TCP flows would need an incoming ACK or RTO timer to add more packets to the pipe. So overall situation should be better now.

2016-12-21net: mvpp2: fix dma unmapping of TX buffers for fragmentsThomas Petazzoni1-29/+30
Since commit 71ce391dfb784 ("net: mvpp2: enable proper per-CPU TX buffers unmapping"), we are not correctly DMA unmapping TX buffers for fragments. Indeed, the mvpp2_txq_inc_put() function only stores in the txq_cpu->tx_buffs[] array the physical address of the buffer to be DMA-unmapped when skb != NULL. In addition, when DMA-unmapping, we use skb_headlen(skb) to get the size to be unmapped. Both of this works fine for TX descriptors that are associated directly to a SKB, but not the ones that are used for fragments, with a NULL pointer as skb: - We have a NULL physical address when calling DMA unmap - skb_headlen(skb) crashes because skb is NULL This causes random crashes when fragments are used. To solve this problem, we need to: - Store the physical address of the buffer to be unmapped unconditionally, regardless of whether it is tied to a SKB or not. - Store the length of the buffer to be unmapped, which requires a new field. Instead of adding a third array to store the length of the buffer to be unmapped, and as suggested by David Miller, this commit refactors the tx_buffs[] and tx_skb[] arrays of 'struct mvpp2_txq_pcpu' into a separate structure 'mvpp2_txq_pcpu_buf', to which a 'size' field is added. Therefore, instead of having three arrays to allocate/free, we have a single one, which also improve data locality, reducing the impact on the CPU cache.

2016-12-21net: ethernet: stmmac: dwmac-rk: make clk enablement first in powerupHeiko Stübner1-4/+4
Right now the dwmac-rk tries to set up the GRF-specific speed and link options before enabling clocks, phys etc and on previous socs this works because the GRF is supplied on the whole by one clock. On the rk3399 however the GRF (General Register Files) clock-supply has been split into multiple clocks and while there is no specific grf-gmac clock like for other sub-blocks, it seems the mac-specific portions are actually supplied by the general mac clock. This results in hangs on rk3399 boards if the driver is build as module. When built in te problem of course doesn't surface, as the clocks are of course still on at the stage before clock_disable_unused. To solve this, simply move the clock enablement to the first position in the powerup callback. This is also a good idea in general to enable clocks before everything else. Tested on rk3288, rk3368 and rk3399 the dwmac still works on all of them. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-12-20sctp: not copying duplicate addrs to the assoc's bind address listXin Long2-0/+6
sctp.local_addr_list is a global address list that is supposed to include all the local addresses. sctp updates this list according to NETDEV_UP/ NETDEV_DOWN notifications. However, if multiple NICs have the same address, the global list would have duplicate addresses. Even if for one NIC, promote secondaries in __inet_del_ifa can also lead to accumulating duplicate addresses. When sctp binds address 'ANY' and creates a connection, it copies all the addresses from global list into asoc's bind addr list, which makes sctp pack the duplicate addresses into INIT/INIT_ACK packets. This patch is to filter the duplicate addresses when copying the addrs from global list in sctp_copy_local_addr_list and unpacking addr_param from cookie in sctp_raw_to_bind_addrs to asoc's bind addr list. Note that we can't filter the duplicate addrs when global address list gets updated, As NETDEV_DOWN event may remove an addr that still exists in another NIC.

2016-12-20mm: fadvise: avoid expensive remote LRU cache draining after FADV_DONTNEEDJohannes Weiner1-1/+14
When FADV_DONTNEED cannot drop all pages in the range, it observes that some pages might still be on per-cpu LRU caches after recent instantiation and so initiates remote calls to all CPUs to flush their local caches. However, in most cases, the fadvise happens from the same context that instantiated the pages, and any pre-LRU pages in the specified range are most likely sitting on the local CPU's LRU cache, and so in many cases this results in unnecessary remote calls, which, in a loaded system, can hold up the fadvise() call significantly. [ I didn't record it in the extreme case we observed at Facebook, unfortunately. We had a slow-to-respond system and noticed it lru_add_drain_all() leading the profile during fadvise calls. This patch came out of thinking about the code and how we commonly call FADV_DONTNEED. FWIW, I wrote a silly directory tree walker/searcher that recurses through /usr to read and FADV_DONTNEED each file it finds. On a 2 socket 40 ht machine, over 1% is spent in lru_add_drain_all(). With the patch, that cost is gone; the local drain cost shows at 0.09%. ] Try to avoid the remote call by flushing the local LRU cache before even attempting to invalidate anything. It's a cheap operation, and the local LRU cache is the most likely to hold any pre-LRU pages in the specified fadvise range.

2016-12-20ima: define a canonical binary_runtime_measurements list formatMimi Zohar6-13/+66
The IMA binary_runtime_measurements list is currently in platform native format. To allow restoring a measurement list carried across kexec with a different endianness than the targeted kernel, this patch defines little-endian as the canonical format. For big endian systems wanting to save/restore the measurement list from a system with a different endianness, a new boot command line parameter named "ima_canonical_fmt" is defined. Considerations: use of the "ima_canonical_fmt" boot command line option will break existing userspace applications on big endian systems expecting the binary_runtime_measurements list to be in platform native format.

2016-12-20powerpc: ima: get the kexec buffer passed by the previous kernelThiago Jung Bauermann7-1/+158
Patch series "ima: carry the measurement list across kexec", v8. The TPM PCRs are only reset on a hard reboot. In order to validate a TPM's quote after a soft reboot (eg. kexec -e), the IMA measurement list of the running kernel must be saved and then restored on the subsequent boot, possibly of a different architecture. The existing securityfs binary_runtime_measurements file conveniently provides a serialized format of the IMA measurement list. This patch set serializes the measurement list in this format and restores it. Up to now, the binary_runtime_measurements was defined as architecture native format. The assumption being that userspace could and would handle any architecture conversions. With the ability of carrying the measurement list across kexec, possibly from one architecture to a different one, the per boot architecture information is lost and with it the ability of recalculating the template digest hash. To resolve this problem, without breaking the existing ABI, this patch set introduces the boot command line option "ima_canonical_fmt", which is arbitrarily defined as little endian. The need for this boot command line option will be limited to the existing version 1 format of the binary_runtime_measurements. Subsequent formats will be defined as canonical format (eg. TPM 2.0 support for larger digests). A simplified method of Thiago Bauermann's "kexec buffer handover" patch series for carrying the IMA measurement list across kexec is included in this patch set. The simplified method requires all file measurements be taken prior to executing the kexec load, as subsequent measurements will not be carried across the kexec and restored. This patch (of 10): The IMA kexec buffer allows the currently running kernel to pass the measurement list via a kexec segment to the kernel that will be kexec'd. The second kernel can check whether the previous kernel sent the buffer and retrieve it. This is the architecture-specific part which enables IMA to receive the measurement list passed by the previous kernel. It will be used in the next patch. The change in machine_kexec_64.c is to factor out the logic of removing an FDT memory reservation so that it can be used by remove_ima_buffer.
