2010-02-03ixgbe: Fix return of invalid txqKrishna Kumar
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).

2010-02-03ixgbe: Fix ixgbe_tx_map error pathAnton Blanchard
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.

2010-02-03dccp: fix auto-loading of dccp(_probe)Gerrit Renker
This fixes commit (38ff3e6bb987ec583268da8eb22628293095d43b) ("dccp_probe: Fix module load dependencies between dccp and dccp_probe", from 15 Jan). It fixes the construction of the first argument of try_then_request_module(), where only valid return codes from the first argument should be returned. What we do now is assign the result of register_jprobe() to ret, without the side effect of the comparison.

This lead to error messages such as FATAL: Error inserting dccp: No buffer space available >> kernel: [ 1456.341501] kmem_cache_create: duplicate cache cci generated due to the truncation after the 3rd character.

2010-02-03netlink: fix for too early rmmodAlexey Dobriyan
Netlink code does module autoload if protocol userspace is asking for is not ready. However, module can dissapear right after it was autoloaded. Example: modprobe/rmmod stress-testing and xfrm_user.ko providing NETLINK_XFRM. netlink_create() in such situation _will_ create userspace socket and _will_not_ pin module.

2010-02-03af_key: fix netns ops ordering on module load/unloadAlexey Dobriyan
1. After sock_register() returns, it's possible to create sockets, even if module still not initialized fully (blame generic module code for that!) 2. Consequently, pfkey_create() can be called with pfkey_net_id still not initialized which will BUG_ON in net_generic(): kernel BUG at include/net/netns/generic.h:43! 3.

Getting it is not used, let's drop support for notifications about (un)registered events from connector. Another option was to check credentials on receiving, but we can always restore it without bugs if needed, but genetlink has a wider code base and none complained, that userspace can not get notification when some other clients were (un)registered.

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.

2010-01-25virtio_net: Make delayed refill more reliableHerbert Xu
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.

2010-01-25sfc: Use fixed-size buffers for MCDI NVRAM requestsBen Hutchings
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).

2010-01-25qlge: Only free resources if they were allocatedBreno Leitao
Currently qlge tries to release regions even if they were not allocated. This causes messages like the following in the kernel log Trying to free nonexistent resource <00000000006af400-00000000006af4ff> Trying to free nonexistent resource <00003c04ff9f4000-00003c04ff9f7fff> Trying to free nonexistent resource <00003c04ffc00000-00003c04ffcfffff> This patch fixes the goto logic in order to not release the resources if they were not allocated.

2010-01-25ath9k: fix eeprom INI values override for 2GHz-only cardsFelix Fietkau
Among other changes, this commit: commit 06d0f0663e11cab4ec5f2c143a118d71a12fbbe9 Author: Sujith <Sujith.Manoharan@atheros.com> Date: Thu Feb 12 10:06:45 2009 +0530 ath9k: Enable Fractional N mode changed the hw attach code to fix up initialization values only for dual band devices, however the commit message did not give a reason as to why this would be useful or necessary. According to tests by Jorge Boncompte, this breaks at least some 2GHz-only cards, so the code should be changed back to the unconditional INI fixup.

2010-01-24netns xfrm: deal with dst entries in netnsAlexey Dobriyan
GC is non-existent in netns, so after you hit GC threshold, no new dst entries will be created until someone triggers cleanup in init_net. Make xfrm4_dst_ops and xfrm6_dst_ops per-netns. This is not done in a generic way, because it woule waste (AF_MAX - 2) * sizeof(struct dst_ops) bytes per-netns. Reorder GC threshold initialization so it'd be done before registering XFRM policies.

Obviously, this register had some other impact that is causing the regression. Either it is masking some other access or needs to be reset in some path.

Found this problem when testing IPv6 from a KVM guest to a remote host via e1000e device on the host.

2010-01-23e1000/e1000e: don't use small hardware rx buffersJesse Brandeburg
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.
