The vlan module cleanup function starts with vlan_netlink_fini(); vlan_ioctl_set(NULL); The first call removes all the vlan devices and the second one closes the vlan ioctl. AFAIS there's a tiny race window between these two calls - after rtnl unregistered all the vlans, but the ioctl handler isn't set to NULL yet, user can manage to call this ioctl and create one vlan device, and that this function will later BUG_ON seeing non-emply hashes. I think, that we must first close the vlan ioctl and only after this remove all the vlans with the vlan_netlink_fini() call.

Packets can be left in the RX ring if the NAPI budget is reached. This is caused by storing the latest rx index at the beginning of bnx2_rx_int(). We may not process all the work up to this index if the budget is reached and so some packets in the RX ring may rot when we later check for more work using this stored rx index. The fix is to not store this latest hw index and only store the processed rx index. We use a new function bnx2_get_hw_rx_cons() to fetch the latest hw rx index.

Recently, Wang Chen submitted a patch (d30f53ae) to move a call to netif_rx(skb) after a subsequent reference to skb, because netif_rx may call kfree_skb on its argument. netif_rx_ni calls netif_rx, so the same problem occurs in the files below. I have left the updating of dev->last_rx after the calls to netif_rx_ni because it seems time dependent, but moved the other field updates before. This was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression skb, e,e1; @@ ( netif_rx(skb); | netif_rx_ni(skb); ) ... when != skb = e ( skb = e1 | * skb ) // </smpl> Signed-off-by: NJulia Lawall <julia@diku.dk> Signed-off-by: NDavid S.

由 Eric W. Biederman 提交于
Ultimately to implement /proc perfectly we need an implementation of d_revalidate because files and directories can be removed behind the back of the VFS, and d_revalidate is the only way we can let the VFS know that this has happened. Unfortunately the linux VFS can not cope with anything in the path to a mount point going away. So a proper d_revalidate method that calls d_drop also needs to call have_submounts which is moderately expensive, so you really don't want a d_revalidate method that unconditionally calls it, but instead only calls it when the backing object has really gone away. proc generic entries only disappear on module_unload (when not counting the fledgling network namespace) so it is quite rare that we actually encounter that case and has not actually caused us real world trouble yet. So until we get a proper test for keeping dentries in the dcache fix the current d_revalidate method by completely removing it. This returns us to the current status quo. So with CONFIG_NETNS=n things should look as they have always looked. For CONFIG_NETNS=y things work most of the time but there are a few rare corner cases that don't behave properly. As the network namespace is barely present in 2.6.24 this should not be a problem. Signed-off-by: NEric W. Biederman <ebiederm@xmission.com> Cc: "Rafael J.

由 Rini van Zetten 提交于
We have a wifi module connected to the spi bus and got sometimes FIFO overrun errors on the spi bus. After some investigation i found that the driver loads the TCR (transmit count) register before the RCR (receive count). When the transfer list is not empty the atmel_spi_next_message is called while tx and rx are enabled. As soon as the TCR is loaded, hardware starts transfer and causes a rx fifo overrun because the RCR is not loaded yet. Load the RCR before the TCR. After this patch the fifo overrun disapears at out setup.

The esp_reset_cleanup() function is called with the host lock held and invokes starget_for_each_device() which wants to take it too. Here is a fix along the lines of shost_for_each_device()/__shost_for_each_device() adding a __starget_for_each_device() counterpart which assumes the lock has already been taken. Eventually, I think the driver should get modified so that more work is done as a softirq rather than in the interrupt context, but for now it fixes a bug that causes the spinlock debugger to fire. While at it, it fixes a small number of cosmetic problems with starget_for_each_device() too. Signed-off-by: NMaciej W. Rozycki <macro@linux-mips.org> Acked-by: NDavid S.

The follow_hugetlb_page() fix I posted (merged as git commit 5b23dbe8) missed one case. If the pte is present, but not writable and write access is requested by the caller to get_user_pages(), the code will do the wrong thing. Rather than calling hugetlb_fault to make the pte writable, it notes the presence of the pte and continues. This simple one-liner makes sure we also fault on the pte for this case. Please apply.

Third rendition of FireWire OHCI 1.0 Isochronous Receive support, using a zer-copy method similar to OHCI 1.1 which puts the IR data payload directly into the userspace buffer. The zero-copy implementation eliminates the video artifacts, audio popping, and buffer underrun problems seen with version 1 of this patch, as well as fixing a regression in OHCI 1.1 support introduced by version 2 of this patch. Successfully tested in OHCI 1.1 mode on the following chipsets: - NEC uPD72847 (rev 01), OHCI 1.1 (PCI) - Ti XIO2200(A) (rev 01), OHCI 1.1 (PCIe) - Ti TSB41AB2 (rev 01), OHCI 1.1 (PCI on SB Audigy) - Apple UniNorth 2 (rev 81), OHCI 1.1 (PowerBook G4 onboard) Successfully tested in OHCI 1.0 mode on the following chipsets: - Agere FW323 (rev 06), OHCI 1.0 (Mac Mini onboard) - Agere FW323 (rev 06), OHCI 1.0 (PCI) - Via VT6306 (rev 46), OHCI 1.0 (PCI) - NEC OrangeLink (rev 01), OHCI 1.0 (PCI) - NEC uPD72847 (rev 01), OHCI 1.1 (PCI) - Ti XIO2200(A) (rev 01), OHCI 1.1 (PCIe) The bulk of testing was done in an x86_64 system, but was also successfully sanity-tested on other systems, including a PPC(32) PowerBook G4 and an i686 EPIA M10k. Crude benchmarking (watching top during capture) puts the cpu utilization during capture on the EPIA's 1GHz Via C3 processor around 13%, which is down from 30% with the v1 code. Some implementation details: To maintain the same userspace API as dual-buffer mode, we set up two descriptors for every incoming packet. The first is an INPUT_MORE descriptor, pointing to a buffer large enough to hold just the packet's iso headers, immediately followed by an INPUT_LAST descriptor, pointing to a chunk of the userspace buffer big enough for the packet's data payload. With this setup, each incoming packet fills in these two descriptors in a manner that very closely emulates dual-buffer receive, to the point where the bulk of the handle_ir_* code is now identical between the two (and probably primed for some restructuring to share code between them). The only caveat I have at the moment is that neither of my OHCI 1.0 Via VT6307-based FireWire controllers work particularly well with this code for reasons I have yet to figure out.
