2015-12-29NFC: st21nfca: Auto-select core moduleChristophe Ricard1-9/+4
The core st21nca module is useless without the I2C access module. So hide NFC_ST21NFCA and select it automatically if either NFC_ST21NFCA_I2C is selected. This avoids presenting NFC_ST21NFCA when NFC_ST21NFCA_I2C can't be selected.

The core st-nci module is useless without either the I2C or the SPI access module. So hide NFC_ST_NCI and select it automatically if either NFC_ST_NCI_I2C or NFC_ST_NCI_SPI is selected. This avoids presenting NFC_ST_NCI when neither NFC_ST_NCI_I2C nor NFC_ST_NCI_SPI can be selected.

2015-12-29lightnvm: wrong offset in bad blk lun calculationMatias Bjørling1-1/+1
dev->nr_luns reports the total number of luns available in a device while dev->luns_per_chnl is the number of luns per channel. When multiple channels are available, the offset is calculated from a channel and lun id into a linear array. As it multiplies with the total number of luns, we go out of bound when channel id > 0 and causes the kernel to panic when we read a protected kernel memory area.

2015-12-28RDMA/be2net: Remove open and close entry pointsDevesh Sharma4-45/+1
Recently Dough Ledford reported a deadlock happening between ocrdma-load sequence and NetworkManager service issueing "open" on be2net interface. The deadlock happens when any be2net hook (e.g. open/close) is called in parallel to insmod ocrdma.ko. A. be2net is sending administrative open/close event to ocrdma holding device_list_mutex. It does this from ndo_open/ndo_stop hooks of be2net. So sequence of locks is rtnl_lock---> device_list lock B. When new ocrdma roce device gets registered, infiniband stack now takes rtnl_lock in ib_register_device() in GID initialization routines. So sequence of locks in this path is device_list lock ---> rtnl_lock. This improper locking sequence causes deadlock. In order to resolve the above deadlock condition, ocrdma intorduced a patch to stop listening to administrative open/close events generated from be2net driver. It now depends on link-state-change async-event generated from CNA. This change leaves behind dead code which used to generate administrative open/close events. This patch cleans-up all that dead code from be2net.

With this patch we stop using administrative open and close events injected by be2net driver. These events were used to dispatch PORT_ACTIVE and PORT_ERROR events to the IB-stack. This patch implements a logic to receive async-link-events generated from CNA whenever link-state-change is detected. Now on, these async-events will be used to dispatch PORT_ACTIVE and PORT_ERROR events to IB-stack. Depending on async-events from CNA removes the need to hold device-list-mutex and thus breaks the busy-wait scenario.

Newer firmware will return the ring group resource when we call hwrm_func_qcaps(). To be compatible with older firmware, use the number of tx rings as the number of ring groups if the older firmware returns 0. When determining how many rx rings we can support, take the ring group resource in account as well in _bnxt_get_max_rings(). Divide and assign the ring groups to VFs.

We need to keep track of all resources, such as rx rings, tx rings, cmpl rings, rss contexts, stats contexts, vnics, after we have divided them for the VFs. Otherwise, subsequent ring changes on the PF may not work correctly. We adjust all max resources in struct bnxt_pf_info after they have been assigned to the VFs. There is no need to keep the separate max_pf_tx_rings and max_pf_rx_rings. When SR-IOV is disabled, we call bnxt_hwrm_func_qcaps() to restore the max resources for the PF.

2015-12-28bnxt_en: Check hardware resources before enabling NTUPLE.Michael Chan2-8/+35
The hardware resources required to enable NTUPLE varies depending on how many rx channels are configured. We need to make sure we have the resources before we enable NTUPLE. Add bnxt_rfs_capable() to do the checking. In addition, we need to do the same checking in ndo_fix_features(). As the rx channels are changed using ethtool -L, we call netdev_update_features() to make the necessary adjustment for NTUPLE. Calling netdev_update_features() in netif_running() state but before calling bnxt_open_nic() would be a problem. To make this work, bnxt_set_features() has to be modified to test for BNXT_STATE_OPEN for the true hardware state instead of checking netif_running().

Also, no need to check for bp->rx_nr_rings as it is always >= 1. If the allocation fails, it is not a fatal error and we can still proceed. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-12-28bnxt_en: support hwrm_func_drv_unrgtr commandJeffrey Huang1-0/+9
During remove_one, the driver should issue hwrm_func_drv_unrgtr command to inform firmware that this function has been unloaded. This is to let firmware keep track of driver present/absent state when driver is gracefully unloaded. A keep alive timer is needed later to keep track of driver state during abnormal shutdown.
