2017-01-13net: thunderx: acpi: fix LMAC initializationVadim Lomovtsev1-5/+6
While probing BGX we requesting appropriate QLM for it's configuration and get LMAC count by that request. Then, while reading configured MAC values from SSDT table we need to save them in proper mapping: BGX[i]->lmac[j].mac = <MAC value> to later provide for initialization stuff. In order to fill such mapping properly we need to add lmac index to be used while acpi initialization since at this moment bgx->lmac_count already contains actual value.

2017-01-13ipmr: improve hash scalabilityNikolay Aleksandrov2-130/+182
Recently we started using ipmr with thousands of entries and easily hit soft lockups on smaller devices. The reason is that the hash function uses the high order bits from the src and dst, but those don't change in many common cases, also the hash table is only 64 elements so with thousands it doesn't scale at all. This patch migrates the hash table to rhashtable, and in particular the rhl interface which allows for duplicate elements to be chained because of the MFC_PROXY support (*,G; *,*,oif cases) which allows for multiple duplicate entries to be added with different interfaces (IMO wrong, but it's been in for a long time). And here are some results from tests I've run in a VM: mr_table size (default, allocated for all namespaces): Before After 49304 bytes 2400 bytes Add 65000 routes (the diff is much larger on smaller devices): Before After 1m42s 58s Forwarding 256 byte packets with 65000 routes (test done in a VM): Before After 3 Mbps / ~1465 pps 122 Mbps / ~59000 pps As a bonus we no longer see the soft lockups on smaller devices which showed up even with 2000 entries before.

2017-01-13svcrdma: avoid duplicate dma unmapping during error recoverySriharsha Basavapatna1-2/+0
In rdma_read_chunk_frmr() when ib_post_send() fails, the error code path invokes ib_dma_unmap_sg() to unmap the sg list. It then invokes svc_rdma_put_frmr() which in turn tries to unmap the same sg list through ib_dma_unmap_sg() again. This second unmap is invalid and could lead to problems when the iova being unmapped is subsequently reused. Remove the call to unmap in rdma_read_chunk_frmr() and let svc_rdma_put_frmr() handle it.

2017-01-13at86rf230: Allow slow GPIO pins for "rstn"Andrey Smirnov1-2/+2
Driver code never touches "rstn" signal in atomic context, so there's no need to implicitly put such restriction on it by using gpio_set_value to manipulate it. Replace gpio_set_value to gpio_set_value_cansleep to fix that. As a an example of where such restriction might be inconvenient, consider a hardware design where "rstn" is connected to a pin of I2C/SPI GPIO expander chip.

This prevents timely freeing of contexts destroyed by client RPC_GSS_PROC_DESTROY requests.

I have reports of a crash that look like __fput() was called twice for a NFSv4.0 file. It seems possible that the state manager could try to reclaim a lock and take a reference on the fl->fl_file at the same time the file is being released if, during the close(), a signal interrupts the wait for outstanding IO while removing locks which then skips the removal of that lock. Since 83bfff23e9ed ("nfs4: have do_vfs_lock take an inode pointer") has removed the need to traverse fl->fl_file->f_inode in nfs4_lock_done(), taking that reference is no longer necessary.

Ursula Braun says: ==================== s390: qeth patches yesterday I came up with 13 qeth patches. Since you have not been happy with the 13th patch, I want to make sure that at least the remaining 12 qeth patches can be applied to net-next. Here is the resend of them. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2017-01-12s390/qeth: fix retrieval of vipa and proxy-arp addressesUrsula Braun1-14/+16
qeth devices in layer3 mode need a separate handling of vipa and proxy-arp addresses. vipa and proxy-arp addresses processed by qeth can be read from userspace. Introduced with commit 5f78e29ceebf ("qeth: optimize IP handling in rx_mode callback") the retrieval of vipa and proxy-arp addresses is broken, if more than one vipa or proxy-arp address are set. The qeth code used local variable "int i" for 2 different purposes. This patch now spends 2 separate local variables of type "int". While touching these functions hash_for_each_safe() is converted to hash_for_each(), since there is no removal of hash entries.

2017-01-12s390/qeth: issue STARTLAN as first IPA commandJulian Wiedmann4-35/+17
STARTLAN needs to be the first IPA command after MPC initialization completes. So move the qeth_send_startlan() call from the layer disciplines into the core path, right after the MPC handshake. While at it, replace the magic LAN OFFLINE return code with the existing enum.
