If we become disconnected from the PCI bus/PCIe fabric, there can be long delays in register reads which can cause erroneous decisions to be made and cause a soft lockup if a lock is held too long. As a preventative measure, check for a disconnection (register reads that return -1) and then disable the board if we find ourselves in this condition. For now, check in our interrupt handlers and the per adapter one second timer. Signed-off-by:

If the execute firmware command fails we do not stop the rest of the initialization process which will continue to fail so if we encounter an error simply short circuit the process. Signed-off-by:

If a fifo full condition is encountered, i/o requests will stack up in the h->reqQ queue. The only thing which empties this queue is start_io, which only gets called when new i/o requests come in. If none are forthcoming, i/o in h->reqQ will be stalled. To fix this, whenever fifo full condition is encountered, this is recorded, and the interrupt handler examines this to see if a fifo full condition was recently encountered when a command completes and will call start_io to prevent i/o's in h->reqQ from getting stuck. I've only ever seen this problem occur when running specialized test programs that pound on the the CCISS_PASSTHRU ioctl. Signed-off-by:

Cap CCISS_BIG_PASSTHRU as well. If an attempt is made to exceed this, ioctl() will return -1 with errno == EAGAIN. This is to prevent a userland program from exhausting all of pci_alloc_consistent memory. I've only seen this problem when running a special test program designed to provoke it. 20 concurrent commands via the passthru ioctls (not counting SG_IO) should be more than enough. Signed-off-by:

The hardware guys tell us that after initiating a software reset via the doorbell register we need to wait 5 seconds before attempting to talk to the board *at all*. This means that we cannot watch the board to verify it transitions from "ready" to to "not ready" then back "ready", since this transition will most likely happen during those 5 seconds (though we can still verify the reset happens by watching the "driver version" field get cleared.)

Migrate sr to make use of block layer runtime PM. Accordingly, the SCSI bus layer runtime PM callback is simplified as all SCSI drivers implementing runtime PM now use the block layer's request-based mechanism. Note that due to the device will be polled by kernel at a constant interval, if the autosuspend delay is set longer than the polling interval then the device will never suspend. Signed-off-by:

Instead of repeatedly calling driver_create_file() to create driver attribute files, This achieves the same thing by constructing an array of driver_attribute and setting it to bus_type->drv_groups. This change simplifies both creation and destruction of the attribute files, and also removes sparse warning caused by driver_attributes which are unnecessarily declared as global. Signed-off-by:

For NUMA systems, initializing the blk-mq layer and using per node hctx. We initialize submit queues to 1, while blk-mq nr_hw_queues is initialized to the number of NUMA nodes. This makes the null_init_hctx function overwrite memory outside of what it allocated. In my case it lead to writing garbage into struct request_queue's mq_map. Signed-off-by:

Since commit ec39f64b ("drm/radeon/dpm: Convert to use devm_hwmon_register_with_groups") radeon_hwmon_init() is using hwmon_device_register_with_groups(), which sets `rdev' as a device private driver_data, while hwmon_attributes_visible() and radeon_hwmon_show_temp_thresh() are still waiting for `drm_device'. Fix them by using dev_get_drvdata(), in order to avoid this oops: BUG: unable to handle kernel paging request at 0000000000001e28 IP: [<ffffffffa02ae8b4>] hwmon_attributes_visible+0x18/0x3d [radeon] PGD 15057e067 PUD 151a8e067 PMD 0 Oops: 0000 [#1] PREEMPT SMP Call Trace: internal_create_group+0x114/0x1d9 sysfs_create_group+0xe/0x10 sysfs_create_groups+0x22/0x5f device_add+0x34f/0x501 device_register+0x15/0x18 hwmon_device_register_with_groups+0xb5/0xed radeon_hwmon_init+0x56/0x7c [radeon] radeon_pm_init+0x134/0x7e5 [radeon] radeon_modeset_init+0x75f/0x8ed [radeon] radeon_driver_load_kms+0xc6/0x187 [radeon] drm_dev_register+0xf9/0x1b4 [drm] drm_get_pci_dev+0x98/0x129 [drm] radeon_pci_probe+0xa3/0xac [radeon] pci_device_probe+0x6e/0xcf driver_probe_device+0x98/0x1c4 __driver_attach+0x5c/0x7e bus_for_each_dev+0x7b/0x85 driver_attach+0x19/0x1b bus_add_driver+0x104/0x1ce driver_register+0x89/0xc5 __pci_register_driver+0x58/0x5b drm_pci_init+0x86/0xea [drm] radeon_init+0x97/0x1000 [radeon] do_one_initcall+0x7f/0x117 load_module+0x1583/0x1bb4 SyS_init_module+0xa0/0xaf Signed-off-by:

Pull networking fixes from David Miller: 1) Revert CHECKSUM_COMPLETE optimization in pskb_trim_rcsum(), I can't figure out why it breaks things. 2) Fix comparison in netfilter ipset's hash_netnet4_data_equal(), it was basically doing "x == x", from Dave Jones. 3) Freescale FEC driver was DMA mapping the wrong number of bytes, from Sebastian Siewior. 4) Blackhole and prohibit routes in ipv6 were not doing the right thing because their ->input and ->output methods were not being assigned correctly. Now they behave properly like their ipv4 counterparts. From Kamala R. 5) Several drivers advertise the NETIF_F_FRAGLIST capability, but really do not support this feature and will send garbage packets if fed fraglist SKBs. From Eric Dumazet. 6) Fix long standing user triggerable BUG_ON over loopback in RDS protocol stack, from Venkat Venkatsubra. 7) Several not so common code paths can potentially try to invoke packet scheduler actions that might be NULL without checking. Shore things up by either 1) defining a method as mandatory and erroring on registration if that method is NULL 2) defininig a method as optional and the registration function hooks up a default implementation when NULL is seen. From Jamal Hadi Salim. 8) Fix fragment detection in xen-natback driver, from Paul Durrant. 9) Kill dangling enter_memory_pressure method in cg_proto ops, from Eric W Biederman. 10) SKBs that traverse namespaces should have their local_df cleared, from Hannes Frederic Sowa. 11) IOCB file position is not being updated by macvtap_aio_read() and tun_chr_aio_read(). From Zhi Yong Wu. 12) Don't free virtio_net netdev before releasing all of the NAPI instances. From Andrey Vagin. 13) Procfs entry leak in xt_hashlimit, from Sergey Popovich. 14) IPv6 routes that are no cached routes should not count against the garbage collection limits. We had this almost right, but were missing handling addrconf generated routes properly. From Hannes Frederic Sowa. 15) fib{4,6}_rule_suppress() have to consider potentially seeing NULL route info when they are called, from Stefan Tomanek. 16) TUN and MACVTAP have had truncated packet signalling for some time, fix from Jason Wang. 17) Fix use after frrr in __udp4_lib_rcv(), from Eric Dumazet. 18) xen-netback does not interpret the NAPI budget properly for TX work, fix from Paul Durrant. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (132 commits) igb: Fix for issue where values could be too high for udelay function. i40e: fix null dereference xen-netback: fix gso_prefix check net: make neigh_priv_len in struct net_device 16bit instead of 8bit drivers: net: cpsw: fix for cpsw crash when build as modules xen-netback: napi: don't prematurely request a tx event xen-netback: napi: fix abuse of budget sch_tbf: use do_div() for 64-bit divide udp: ipv4: must add synchronization in udp_sk_rx_dst_set() net:fec: remove duplicate lines in comment about errata ERR006358 Revert "8390 : Replace ei_debug with msg_enable/NETIF_MSG_* feature" 8390 : Replace ei_debug with msg_enable/NETIF_MSG_* feature xen-netback: make sure skb linear area covers checksum field net: smc91x: Fix device tree based configuration so it's usable udp: ipv4: fix potential use after free in udp_v4_early_demux() macvtap: signal truncated packets tun: unbreak truncated packet signalling net: sched: htb: fix the calculation of quantum net: sched: tbf: fix the calculation of max_size micrel: add support for KSZ8041RNLI ... -

Pull x86 fixes from Peter Anvin: "This is a pretty small batch: The biggest single change is to stop using EFI time services on 32-bit platforms. This matches our current behavior on 64-bit platforms as we already had ruled them out there as being too unreliable. Turns out that affects 32-bit platforms, too. One NULL pointer fix for SGI UV.

This reverts commit 102aefdd. Tom London reports that it causes sync() to hang on Fedora rawhide: https://bugzilla.redhat.com/show_bug.cgi?id=1033965 and Josh Boyer bisected it down to this commit. Reverting the commit in the rawhide kernel fixes the problem. Eric Paris root-caused it to incorrect subtype matching in that commit breaking fuse, and has a tentative patch, but by now we're better off retrying this in 3.14 rather than playing with it any more.
