* drivers/net: Correct NULL testJulia Lawall2010-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | Test the value that was just allocated rather than the previously tested one. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ expression *x; expression e; identifier l; @@ if (x == NULL || ...) { ... when forall return ...; } ... when != goto l; when != x = e when != &x *x == NULL // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

* igb: make certain to reassign legacy interrupt vectors after resetAlexander Duyck2010-02-04
| | | | | | | | | | | | | | | This change corrects an issue that will cause false hangs when using either 82575 or 82580 in legacy interrupt mode. The issue is caused when there is a slow traffic flow and an "ethtool -r" is executed while using legacy or MSI interrupts. MSI-X is not affected by this issue due to the fact that we were already reconfiguring the vectors after reset. If possible it would be best to push this for net-2.6 since it is resolving a bug but if that is not possible then net-next-2.6 will be fine.

* ixgbe: Fix return of invalid txqKrishna Kumar2010-02-03
| | | | | | | | | | | | | | | | | | a developer had complained of getting lots of warnings: "eth16 selects TX queue 98, but real number of TX queues is 64" http://www.mail-archive.com/e1000-devel@lists.sourceforge.net/msg02200.html As there was no follow up on that bug, I am submitting this patch assuming that the other return points will not return invalid txq's, and also that this fixes the bug (not tested).

| | | | | | | | | | | | | Commit e5a43549f7a58509a91b299a51337d386697b92c (ixgbe: remove skb_dma_map/unmap calls from driver) looks to have introduced a bug in ixgbe_tx_map. If we get an error from a PCI DMA call, we loop backwards through count until it becomes -1 and return that. The caller of ixgbe_tx_map expects 0 on error, so return that instead.

* cdc_ether: Partially revert "usbnet: Set link down initially ..."Ben Hutchings2010-01-29
| | | | | | | | | | | | | | | Commit 37e8273cd30592d3a82bcb70cbb1bdc4eaeb6b71 ("usbnet: Set link down initially for drivers that update link state") changed the initial link state in cdc_ether and other drivers based on the understanding that the devices they support generate link change interrupts. However, this is optional in the CDC Ethernet protocol, and two users have reported in <http://bugzilla.kernel.org/show_bug.cgi?id=14791> that the link state for their devices remains down. Therefore, revert the change in cdc_ether. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Tested-by: Avi Rozen <avi.rozen@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When cleaning up beacon buffers and slots, ath9k currently checks if sc->ah->opmode is set to a beacon related mode before cleaning up buffers. An unfortunate ordering of interface up/down commands can lead to sc->ah->opmode being set to monitor mode, while there are AP interfaces present on the same wiphy.

* | virtio_net: Make delayed refill more reliableHerbert Xu2010-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have seen RX stalls on a machine that experienced a suspected OOM. After the stall, the RX buffer is empty on the guest side and there are exactly 16 entries available on the host side. As the number of entries is less than that required by a maximal skb, the host cannot proceed. The guest did not have a refill job scheduled. My diagnosis is that an OOM had occured, with the delayed refill job scheduled. The job was able to allocate at least one skb, but not enough to overcome the minimum required by the host to proceed. As the refill job would only reschedule itself if it failed completely to allocate any skbs, this would lead to an RX stall. The following patch removes this stall possibility by always rescheduling the refill job until the ring is totally refilled. Testing has shown that the RX stall no longer occurs whereas previously it would occur within a day.

* | sfc: Use fixed-size buffers for MCDI NVRAM requestsBen Hutchings2010-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | The low-level MCDI code always uses 32-bit MMIO operations, and callers must pad input and output buffers to multiples of 4 bytes. The MCDI NVRAM functions are not doing this. Also, their buffers are declared as variable-length arrays with no explicit maximum length. Switch to a fixed buffer size based on the chunk size used by the MTD driver (which is a multiple of 4). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

Extend the stats buffer to support this. The length of the buffer is explicit in the MAC_STATS command, so this change is backward-compatible on both sides.

* | e1000/e1000e: don't use small hardware rx buffersJesse Brandeburg2010-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When testing the "e1000: enhance frame fragment detection" (and e1000e) patches we found some bugs with reducing the MTU size. The 1024 byte descriptor used with the 1000 mtu test also (re) introduced the (originally) reported bug, and causes us to need the e1000_clean_tx_irq "enhance frame fragment detection" fix. So what has occured here is that 2.6.32 is only vulnerable for mtu < 1500 due to the jumbo specific routines in both e1000 and e1000e. So, 2.6.32 needs the 2kB buffer len fix for those smaller MTUs, but is not vulnerable to the original issue reported. It has been pointed out that this vulnerability needs to be patched in older kernels that don't have the e1000 jumbo routine. Without the jumbo routines, we need the "enhance frame fragment detection" fix the e1000, old e1000e is only vulnerable for < 1500 mtu, and needs a similar fix. We split the patches up to provide easy backport paths. There is only a slight bit of extra code when this fix and the original "enhance frame fragment detection" fixes are applied, so please apply both, even though it is a bit of overkill.

Although this is against the PCI specification, we can handle it quite easily by allowing drivers to define arbitrary D3 delays for devices known to require extra time for switching power states. Introduce additional field d3_delay in struct pci_dev and use it to store the value of the device's D0->D3 delay, in miliseconds. Make the PCI PM core code use the per-device d3_delay unless pci_pm_d3_delay is greater (in which case the latter is used). [This also allows the driver to specify d3_delay shorter than the 10 ms required by the PCI standard if the device is known to be able to handle that.] Make the sky2 driver set d3_delay to 150 for devices handled by it.

The current kernel fifo API is not very widely used, because it has to many constrains. Only 17 files in the current 2.6.31-rc5 used it. FIFO's are like list's a very basic thing and a kfifo API which handles the most use case would save a lot of development time and memory resources. I think this are the reasons why kfifo is not in use: - The API is to simple, important functions are missing - A fifo can be only allocated dynamically - There is a requirement of a spinlock whether you need it or not - There is no support for data records inside a fifo So I decided to extend the kfifo in a more generic way without blowing up the API to much. The new API has the following benefits: - Generic usage: For kernel internal use and/or device driver. - Provide an API for the most use case. - Slim API: The whole API provides 25 functions. - Linux style habit. - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros - Direct copy_to_user from the fifo and copy_from_user into the fifo. - The kfifo itself is an in place member of the using data structure, this save an indirection access and does not waste the kernel allocator. - Lockless access: if only one reader and one writer is active on the fifo, which is the common use case, no additional locking is necessary. - Remove spinlock - give the user the freedom of choice what kind of locking to use if one is required. - Ability to handle records. Three type of records are supported: - Variable length records between 0-255 bytes, with a record size field of 1 bytes. - Variable length records between 0-65535 bytes, with a record size field of 2 bytes. - Fixed size records, which no record size field. - Preserve memory resource. - Performance! - Easy to use! This patch: Since most users want to have the kfifo as part of another object, reorganize the code to allow including struct kfifo in another data structure. This requires changing the kfifo_alloc and kfifo_init prototypes so that we pass an existing kfifo pointer into them. This patch changes the implementation and all existing users.
