We added some security checks in commit 57fe93b3 (filter: make sure filters dont read uninitialized memory) to close a potential leak of kernel information to user. This added a potential extra cost at run time, while we can perform a check of the filter itself, to make sure a malicious user doesnt try to abuse us. This patch adds a check_loads() function, whole unique purpose is to make this check, allocating a temporary array of mask. We scan the filter and propagate a bitmask information, telling us if a load M(K) is allowed because a previous store M(K) is guaranteed. (So that sk_run_filter() can possibly not read unitialized memory) Note: this can uncover application bug, denying a filter attach, previously allowed. Signed-off-by:

Only when dont_send is 0, arp_filter() is consulted, so we can simply assign the return value of arp_filter() to dont_send instead. Signed-off-by:

If Lancer chip does not have posted RX buffers, it posts an RX completion entry with the same frag_index as the last valid completion. The Error bit is also set. In BE, a flush completion is indicated with a zero value for num_rcvd in the completion. Such completions don't carry any data and are not processed. This patch refactors code to handle both cases with the same code. Signed-off-by:

As we can check if an address is vmalloc address with is_vmalloc_addr(), we remove pgv.flags. Then we may get more pg_vecs. Signed-off-by:

The following commit causes the pgv->buffer may point to the memory returned by vmalloc(). And we can't use virt_to_page() for the vmalloc address. This patch introduces a new inline function pgv_to_page(), which calls vmalloc_to_page() for the vmalloc address, and virt_to_page() for the __get_free_pages address. We used to increase page pointer to get the next page at the next page address, after Neil's patch, it is wrong, as the physical address may be not continuous. This patch also fixes this issue. commit 0e3125c7 Author: Neil Horman <nhorman@tuxdriver.com> Date: Tue Nov 16 10:26:47 2010 -0800 packet: Enhance AF_PACKET implementation to not require high order contiguous memory allocation (v4) Signed-off-by: -

commits 9f0f7272 (ipv4: AF_INET link address family) and cf7afbfe (rtnl: make link af-specific updates atomic) used incorrect __in_dev_get_rcu() in RTNL protected contexts, triggering PROVE_RCU warnings. Switch to __in_dev_get_rtnl(), wich is more appropriate, since we hold RTNL. Based on a report and initial patch from Amerigo Wang. Reported-by:

Add SKF_AD_RXHASH and SKF_AD_CPU to filter ancillary mechanism, to be able to build advanced filters.

The patch provides USB CDC NCM host driver support in the Linux Kernel. Changes: drivers/net/usb/cdc_ncm.c: - initial submission of the CDC NCM host driver; - verified on Intel 32/64 bit, Intel Atom, ST-Ericsson U8500 (ARM) - throughput measured over 100 Mbits duplex; - driver supports 16-bit NTB format only, but it is more than enough for transfers up to 64K; - driver can handle up to 32 datagrams in received NTB; - timer is used to collect several packets in Tx direction drivers/net/usb/Kconfig: - a new entry to compile CDC NCM host driver drivers/net/usb/Makefile: - a new entry to compile CDC NCM host driver Signed-off-by:

The first hunk of this patch makes sure that the driver checks for the appropriate preconditions before checking if EEE negotiation succeeded. More specifically the link needs to be full duplex for EEE to be enabled. The second and third hunks of this patch fix a bug where the eee advertisement register would be programmed with extra bits set. The fourth hunk of this patch makes sure the EEE capability flag is not set for 5718 A0 devices and that the device is not a serdes device. None of these modifications are strictly necessary. The driver / hardware still does the right thing. They are submitted primarily for correctness. Signed-off-by:
