Miller <[email protected]>
2015-06-25mlx4: Disable HA for SRIOV PF RoCE devicesOr Gerlitz1-1/+7
When in HA mode, the driver exposes an IB (RoCE) device instance with only one port. Under SRIOV, the existing implementation doesn't go well with the PF RoCE driver's role of Special QPs Para-Virtualization, etc. As such, disable HA for the mlx4 PF RoCE device in SRIOV mode.

2015-06-25net/mlx4_en: Fix wrong csum complete report when rxvlan offload is disabledIdo Shamay1-11/+6
The check_csum() function relied on hwtstamp_rx_filter to know if rxvlan offload is disabled. This is wrong since rxvlan offload can be switched on/off regardless of hwtstamp_rx_filter. Also moved check_csum to query CQE information to identify VLAN packets and removed the check of IP packets, since it has been validated before.

2015-06-25net/mlx4_en: Wake TX queues only when there's enough roomIdo Shamay2-8/+12
Indication of a single completed packet, marked by txbbs_skipped being bigger then zero, in not enough in order to wake up a stopped TX queue. The completed packet may contain a single TXBB, while next packet to be sent (after the wake up) may have multiple TXBBs (LSO/TSO packets for example), causing overflow in queue followed by WQE corruption and TX queue timeout. Instead, wake the stopped queue only when there's enough room for the worst case (maximum sized WQE) packet that we should need to handle after the queue is opened again. Also created an helper routine - mlx4_en_is_tx_ring_full, which checks if the current TX ring is full or not. It provides better code readability and removes code duplication.

2015-06-25libnvdimm: infrastructure for btt devicesDan Williams13-99/+879
NVDIMM namespaces, in addition to accepting "struct bio" based requests, also have the capability to perform byte-aligned accesses. By default only the bio/block interface is used. However, if another driver can make effective use of the byte-aligned capability it can claim namespace interface and use the byte-aligned ->rw_bytes() interface. The BTT driver is the initial first consumer of this mechanism to allow adding atomic sector update semantics to a pmem or blk namespace. This patch is the sysfs infrastructure to allow configuring a BTT instance for a namespace. Enabling that BTT and performing i/o is in a subsequent patch.

2015-06-25s390/kdump: fix nosmt kernel parameterMichael Holzheu7-61/+64
It turned out that SIGP set-multi-threading can only be done once. Therefore switching to a different MT level after switching to sclp.mtid_prev in the dump case fails. As a symptom specifying the "nosmt" parameter currently fails for the kdump kernel and the kernel starts with multi-threading enabled. So fix this and issue diag 308 subcode 1 call after collecting the CPU states for the dump. Also enhance the diag308_reset() function to be usable also with enabled lowcore protection and prefix register != 0. After the reset it is possible to switch the MT level again. We have to do the reset very early in order not to kill the already initialized console. Therefore instead of kmalloc() the corresponding memblock functions have to be used. To avoid copying the sclp cpu code into sclp_early, we now use the simple sigp loop method for CPU detection.

2015-06-25s390/smp: cleanup core vs. cpu in the SCLP interfaceMartin Schwidefsky5-52/+50
The SCLP interface to query, configure and deconfigure CPUs actually operates on cores. For a machine without the multi-threading faciltiy a CPU and a core are equivalent but starting with System z13 a core can have multiple hardware threads, also referred to as logical CPUs. To avoid confusion replace the word 'cpu' with 'core' in the SCLP interface. Also replace MAX_CPU_ADDRESS with SCLP_MAX_CORES. The core-id is an 8-bit field, the maximum thread id is in the range 0-31. The theoretical limit for the CPU address is therefore 8191. Signed-off-by: Martin Schwidefsky <[email protected]>

2015-06-25s390/zcrypt: Fixed reset and interrupt handling of AP queuesIngo Tuchscherer3-200/+239
In case of request timeouts an AP queue reset will be triggered to recover and reinitialize the AP queue. The previous behavior was an immediate reset execution regardless of current/pending requests. Due to newly changed firmware behavior the reset may be delayed, based on the priority of pending request. The device driver's waiting time frame was limited, hence it did not received the reset response. As a consequence interrupts would not be enabled afterwards. The RAPQ (queue reset) and AQIC (interrupt control) commands will be treated fully asynchronous now. The device driver will check the reset and interrupt states periodically, thus it can handle the reinitialization properly.

Currently all backward jumps crash for JITed s390x eBPF programs with an illegal instruction program check and kernel panic. Because for negative values the opcode of the jump instruction is overriden by the negative branch offset an illegal instruction is generated by the JIT: 000003ff802da378: c01100000002 lgfi %r1,2 000003ff802da37e: fffffff52065 unknown <-- illegal instruction 000003ff802da384: b904002e lgr %r2,%r14 So fix this and mask the offset in order not to damage the opcode.

2015-06-25md: clear Blocked flag on failed devices when array is read-only.Neil Brown1-0/+9
The Blocked flag indicates that a device has failed but that this fact hasn't been recorded in the metadata yet. Writes to such devices cannot be allowed until the metadata has been updated. On a read-only array, the Blocked flag will never be cleared. This prevents the device being removed from the array. If the metadata is being handled by the kernel (i.e. !mddev->external), then we can be sure that if the array is switch to writable, then a metadata update will happen and will record the failure. So we don't need the flag set. If metadata is externally managed, it is upto the external manager to clear the 'blocked' flag.

2015-06-25md: clear mddev->private when it has been freed.NeilBrown1-0/+3
If ->private is set when ->run is called, it is assumed to be a 'config' prepared as part of 'reshape'. So it is important when we free that config, that we also clear ->private. This is not often a problem as the mddev will normally be discarded shortly after the config us freed. However if an 'assemble' races with a final close, the assemble can use the old mddev which has a stale ->private. This leads to any of various sorts of crashes. So clear ->private after calling ->free().

2015-06-25firmware: dmi_scan: add SBMIOS entry and DMI tablesIvan Khoronzhuk5-9/+111
Some utils, like dmidecode and smbios, need to access SMBIOS entry table area in order to get information like SMBIOS version, size, etc. Currently it's done via /dev/mem. But for situation when /dev/mem usage is disabled, the utils have to use dmi sysfs instead, which doesn't represent SMBIOS entry and adds code/delay redundancy when direct access for table is needed. So this patch creates dmi/tables and adds SMBIOS entry point to allow utils in question to work correctly without /dev/mem. Also patch adds raw dmi table to simplify dmi table processing in user space, as proposed by Jean Delvare.

The SMBIOS specification explicitly says that end-of-table markers should be ignored if they are not actually at the end of the DMI table.
