This helps to prevent a problem where the primary adapter can get shut down before the secondary adapter and cause the secondary adapter to fail over and log and error. This patch also removes the "enable_cache" paramater as it is obsolete. Write cache for an adapter is now controlled from the iprconfig utility.

This causes two problems. Firstly if SCSI == n just defining scsi_is_sdev_device() to return false might not be enough to prevent gcc from emitting the code (and thus referring to undefined symbols), so this needs surrounding with an ifdef. Secondly, using scsi_is_sdev_device() when SCSI is either y or m gives a subtle problem in the m case: raid_attrs must also be m to use the symbol. Do the usual Kconfig jiggery-pokery to fix this.

Brocade CNA currently supports only 190 vports (instead of 191), since there are only 192 unicast cam entries reserved for FCoE. Brocade CNA has a total of 256 unicast cam entries (192 FCoE + 64 LL) 192 cam entries = 1 burned in mac + 1 baseport FPMA mac + 190 vport FPMA macs.

Replace enum types with int and rearrange the fields to fix some alignment issue. Local var ioc_attr is causing the stack to overflow, so removed the usage of the local ioc_attr var and now invoking an API to return the ioc_type. Fix some AEN issues.

MS module did not invoke fdmi offline in all cases, call fdmi offline when ms module receives a port offline, so that fdmi offline is from one place in the ms module. Make changes to handle 10G speed in the conversion routine. Replaced the usage of bfa_adapter_attr_s struct with specific API's.

This hooks up the ->set_affinity() for the INTC controllers, which can be done as just a simple copy of the cpumask. The enable/disable paths already handle SMP register strides, so we just test the affinity mask in these paths to determine which strides to skip over. The early enable/disable path happens prior to the IRQs being registered, so we have no affinity mask established at that point, in which case we just default to CPU_MASK_ALL. This is left as it is to permit the force enable/disable code to retain existing semantics.

It happen while in a mistake each request sent twice for the same vport. This interface is asynchronous, entering the delete request into a work queue, allowing more than one request to enter to the delete work queue. The result is a NULL pointer. The first request already delete the vport, while the second request got a pointer to the vport before the device destroyed. Re-create vport later cause system freeze.

We can get this driver enabled via MFD_TIMBERDALE which only requires GPIO to be on. But the of_address_to_resource() function is only present on powerpc and microblaze, so we have to conditionalize the CONFIG_OF probing bits on that. Signed-off-by: David S.

The first is just enable PCI in Makefiles and in Kconfig. The second is the rest of missing files. I didn't want to add it with previous patch because that patch is too big. Current Microblaze toolchain has problem with weak symbols that's why is necessary to apply this changes to be possible to compile pci support. Xilinx knows about this problem.

Re-arrange the handling of these register swaps so that PL111 always gets it right without resorting to ifdefs, leaving the only case needing special handling being PL110 on Versatile. Fill out amba/clcd.h with the PL110/PL111 register definition differences in case someone tries to use the PL110 specific definitions on PL111.

If a component device has a merge_bvec_fn then as we never call it we must ensure we never need to. Currently this is done by setting max_sector to 1 PAGE, however this does not stop a bio being created with several sub-page iovecs that would violate the merge_bvec_fn. So instead set max_segments to 1 and set the segment boundary to the same as a page boundary to ensure there is only ever one single-page segment of IO requested at a time. This can particularly be an issue when 'xen' is used as it is known to submit multiple small buffers in a single bio.

Currently the driver handles default state this way: memset(&led, 0, sizeof(led)); for_each_child_of_node(np, child) { state = of_get_property(child, "default-state", NULL); if (state) { if (!strcmp(state, "keep")) led.default_state = LEDS_GPIO_DEFSTATE_KEEP; ... } ret = create_gpio_led(&led, ...); } Which means that all LEDs that do not specify default-state will inherit the last value of the default-state property, which is wrong. This patch fixes the issue by moving LED's template initialization into the loop body.

Ari writes as the reason this should be reverted: The problems with this patch include: 1. There's at least one subtlety I overlooked - switching between X servers (i.e. from one X VT to another) still requires the cooperation of both X servers. I was assuming that KMS eliminated this. 2. It hasn't been tested at all (no X server patch exists which uses the new mode). As he was the original author of the patch, I'll revert it.

In addition tty_hangup(tty) is problematic as tty_hangup is asynchronous itself.... So this can happen hvc_close hvc_remove hung up ? - no lock tty = hp->tty unlock lock hp->tty = NULL unlock notify del kref_put the hvc struct close completes tty is destroyed tty_hangup dead tty tty->ops will be NULL NULL->...

The error is: ftdi_sio ttyUSB0: ftdi_submit_read_urb - failed submitting read urb, error -22 The handling of the ASYNCB_INITIALIZED changed in 2.6.32 such that in tty_port_shutdown() it always clears the flag if it is set.

This fixes potential null pointer dereferences in the generic open and write routines, as well as access to uninitialised fifo in write_room and chars_in_buffer. Also let write fail with ENODEV (instead of 0) on missing out endpoint (also on zero-length writes).

If an error occurs, and the skb needs to be returned to the RX recycle queue, the current code attempts to reset head, but did not reset tail. This patch remembers the alignment amount, and reverses the reserve() when needed. Signed-off-by: Ben Menchaca Signed-off-by: David S.

One of the benefits of absolute round-robin transmit. Keeping track of subscribed multicast groups for each slave did not seem like a good use of resources, so I decided to simply send on the curr_active slave of the bond (typically the first enslaved device that is up). This makes failover management simple as IGMP membership reports only need to be sent when the curr_active_slave changes. I tested this patch and it appears to work as expected.

Based on this initial thread: http://marc.info/?l=linux-netdev&m=126202972828626&w=1 This is the official patch to fix the frame length problems in the r8169 driver. As noted in the previous thread, while this patch incurs a performance hit on the driver, its possible to improve performance dynamically by updating the mtu and rx_copybreak values at runtime to return performance to what it was for those NICS which are unaffected by the ideosyncracy (if there are any). Summary: A while back Eric submitted a patch for r8169 in which the proper allocated frame size was written to RXMaxSize to prevent the NIC from dmaing too much data. This was done in commit fdd7b4c3302c93f6833e338903ea77245eb510b4. A long time prior to that however, Francois posted 126fa4b9ca5d9d7cb7d46f779ad3bd3631ca387c, which expiclitly disabled the MaxSize setting due to the fact that the hardware behaved in odd ways when overlong frames were received on NIC's supported by this driver. This was mentioned in a security conference recently: http://events.ccc.de/congress/2009/Fahrplan//events/3596.en.html It seems that if we can't enable frame size filtering, then, as Eric correctly noticed, we can find ourselves DMA-ing too much data to a buffer, causing corruption. As a result is seems that we are forced to allocate a frame which is ready to handle a maximally sized receive. This obviously has performance issues with it, so to mitigate that issue, this patch does two things: 1) Raises the copybreak value to the frame allocation size, which should force appropriately sized packets to get allocated on rx, rather than a full new 16k buffer. 2) This patch only disables frame filtering initially (i.e., during the NIC open), changing the MTU results in ring buffer allocation of a size in relation to the new mtu (along with a warning indicating that this is dangerous). Because of item (2), individuals who can't cope with the performance hit (or can otherwise filter frames to prevent the bug), or who have hardware they are sure is unaffected by this issue, can manually lower the copybreak and reset the mtu such that performance is restored easily.
