2009-11-17macvlan: Precise RX stats accountingEric Dumazet
With multi queue devices, its possible that several cpus call macvlan RX routines simultaneously for the same macvlan device. We update RX stats counter without any locking, so we can get slightly wrong counters. One possible fix is to use percpu counters, to get precise accounting and also get guarantee of no cache line ping pongs between cpus. Note: this adds 16 bytes (32 bytes on 64bit arches) of percpu data per macvlan device. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-11-17net: Getting rid of the x86 dependency to built vmxnet3Shreyas Bhatewara
This patch removes config dependency on x86 to build vmxnet3 driver. Thus the driver can be built on big endian architectures now. Although vmxnet3 is not supported on VMs other than x86 architecture, all this code goes in to ensure correctness. If the code is not dependent on x86, it should not assume little endian architecture in any of its operations. Signed-off-by: Shreyas Bhatewara <sbhatewara@vmware.com> Signed-off-by: David S.

2009-11-16ppp: fix BUG on non-linear SKB (multilink receive)Ben McKeegan
PPP does not correctly call pskb_may_pull() on all necessary receive paths before reading the PPP protocol, thus causing PPP to report seemingly random 'unsupported protocols' and eventually trigger BUG_ON(skb->len < skb->data_len) in skb_pull_rcsum() when receiving multilink protocol in non-linear skbs. ppp_receive_nonmp_frame() does not call pskb_may_pull() before reading the protocol number. For the non-mp receive path this is not a problem, as this check is done in ppp_receive_frame(). For the mp receive path, ppp_mp_reconstruct() usually copies the data into a new linear skb. However, in the case where the frame is made up of a single mp fragment, the mp header is pulled and the existing skb used. This skb was then passed to ppp_receive_nonmp_frame() without checking if the encapsulated protocol header could safely be read.

2009-11-15bonding: fix 802.3ad standards compliance errorJay Vosburgh
The language of 802.3ad 43.4.9 requires the "recordPDU" function to, in part, compare the Partner parameter values in a received LACPDU to the stored Actor values. If those match, then the Partner's synchronization state is set to true. The current 802.3ad implementation is performing these steps out of order; first, the synchronization check is done, then the paramters are checked to see if they match (the synch check being done against a match check of a prior LACPDU). This causes delays in establishing aggregators in some circumstances. This patch modifies the 802.3ad code to call __choose_matched, the function that does the "match" comparisions, as the first step of __record_pdu, instead of immediately afterwards. This new behavior is in compliance with the language of the standard. Some additional commentary relating to code vs. standard is also added. Reported by Martin Patterson <martin@gear6.com> who also supplied the logic of the fix and verified the patch. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.

2009-11-15TI Davinci EMAC : Fix Console Hang when bringing the interface downSriram
In the NAPI poll function(emac_poll), check for netif_running() is unnecassary. In addition to associated runtime overhead, it also results in a continuous softirq loop when the interface is brought down under heavy traffic(tested wit Traffic Generator). Once the interface is disabled, the poll function always returns zero(with the check for netif_running) and napi_complete() would never get called resulting in softirq loop.
