2011-03-28net: Always allocate at least 16 skb frags regardless of page sizeAnton Blanchard1-1/+7
When analysing performance of the cxgb3 on a ppc64 box I noticed that we weren't doing much GRO merging. It turns out we are limited by the number of SKB frags: #define MAX_SKB_FRAGS (65536/PAGE_SIZE + 2) With a 4kB page size we have 18 frags, but with a 64kB page size we only have 3 frags. I ran a single stream TCP bandwidth test to compare the performance of Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-27net: fix ethtool->set_flags not intended -EINVAL return valueStanislaw Gruszka1-0/+1
After commit d5dbda23804156ae6f35025ade5307a49d1db6d7 "ethtool: Add support for vlan accleration.", drivers that have NETIF_F_HW_VLAN_TX, and/or NETIF_F_HW_VLAN_RX feature, but do not allow enable/disable vlan acceleration via ethtool set_flags, always return -EINVAL from that function. Fix by returning -EINVAL only if requested features do not match current settings and can not be changed by driver. Change any driver that define ethtool->set_flags to use ethtool_invalid_flags() to avoid similar problems in the future (also on drivers that do not have the problem). Tested with modified (to reproduce this bug) myri10ge driver. Cc: stable@kernel.org # 2.6.37+ Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: David S.

2011-03-27rose: Add length checks to CALL_REQUEST parsingBen Hutchings1-1/+7
Define some constant offsets for CALL_REQUEST based on the description at <http://www.techfest.com/networking/wan/x25plp.htm> and the definition of ROSE as using 10-digit (5-byte) addresses. Use them consistently. Validate all implicit and explicit facilities lengths. Validate the address length byte rather than either trusting or assuming its value.

2011-03-25route: Take the right src and dst addresses in ip_route_newportsSteffen Klassert1-2/+2
When we set up the flow informations in ip_route_newports(), we take the address informations from the the rt_key_src and rt_key_dst fields of the rtable. They appear to be empty. So take the address informations from rt_src and rt_dst instead. This issue was introduced by commit 5e2b61f78411be25f0b84f97d5b5d312f184dfd1 ("ipv4: Remove flowi from struct rtable.")

2011-03-24net_sched: fix THROTTLED/RUNNING raceEric Dumazet1-4/+4
commit fd245a4adb52 (net_sched: move TCQ_F_THROTTLED flag) added a race. qdisc_watchdog() is run from softirq, so special care should be taken or we can lose one state transition (THROTTLED/RUNNING) Prior to fd245a4adb52, we were manipulating q->flags (qdisc->flags &= ~TCQ_F_THROTTLED;) and this manipulation could only race with qdisc_warn_nonwc(). Since we want to avoid atomic ops in qdisc fast path - it was the meaning of commit 371121057607e (QDISC_STATE_RUNNING dont need atomic bit ops) - fix is to move THROTTLE bit into 'state' field, this one being manipulated with SMP and IRQ safe operations.

2011-03-23mlx4: Add blue flame support for kernel consumersEli Cohen2-0/+14
Using blue flame can improve latency by allowing the HW to more efficiently access the WQE. This patch presents two functions that are used to allocate or release HW resources for using blue flame; the caller need to supply a struct mlx4_bf object when allocating resources. Consumers that make use of this API should post doorbells to the UAR object pointed by the initialized struct mlx4_bf; Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: David S.

Adding a pool of MSI-X vectors and EQs that can be used explicitly by mlx4_core customers (mlx4_ib, mlx4_en). The consumers will assign their own names to the interrupt vectors. Those vectors are not opened at mlx4 device initialization, opened by demand. Changed the max number of possible EQs according to the new scheme, no longer relies on on number of cores.

2011-03-22ipv4: fix route deletion for IPs on many subnetsJulian Anastasov1-0/+1
Alex Sidorenko reported for problems with local routes left after IP addresses are deleted. It happens when same IPs are used in more than one subnet for the device. Fix fib_del_ifaddr to restrict the checks for duplicate local and broadcast addresses only to the IFAs that use our primary IFA or another primary IFA with same address. And we expect the prefsrc to be matched when the routes are deleted because it is possible they to differ only by prefsrc. This patch prevents local and broadcast routes to be leaked until their primary IP is deleted finally from the box. As the secondary address promotion needs to delete the routes for all secondaries that used the old primary IFA, add option to ignore these secondaries from the checks and to assume they are already deleted, so that we can safely delete the route while these IFAs are still on the device list.

2011-03-21IPVS: Use global mutex in ip_vs_app.cSimon Horman1-2/+0
As part of the work to make IPVS network namespace aware __ip_vs_app_mutex was replaced by a per-namespace lock, ipvs->app_mutex. ipvs->app_key is also supplied for debugging purposes. Unfortunately this implementation results in ipvs->app_key residing in non-static storage which at the very least causes a lockdep warning. This patch takes the rather heavy-handed approach of reinstating __ip_vs_app_mutex which will cover access to the ipvs->list_head of all network namespaces.

2011-03-18spi/dw_spi: move dw_spi.h into drivers/spiGrant Likely1-234/+0
include/linux/dw_spi.h only includes driver internal data. It doesn't expose a platform_data configuration structure or similar (at least nothing in-tree). This patch moves the header into drivers/spi so that the scope is limited to only the dw_spi_*.c driver files Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Feng Tang <feng.tang@intel.com> Cc: spi-devel-general@lists.sourceforge.net
