2010-09-21dccp ccid-3: Remove redundant 'options_received' structGerrit Renker
The `options_received' struct is redundant, since it re-duplicates the existing `p' and `x_recv' fields. This patch removes the sub-struct and migrates the format conversion operations to ccid3_hc_tx_parse_options(). Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
2010-09-21dccp tfrc/ccid-3: computing the loss rate from the Loss Event RateGerrit Renker
This adds a function to take care of the following, separate cases occurring in the computation of the Loss Rate p: * 1/(2^32-1) is mapped into 0% as per RFC 4342, 8.5; * 1/0 is mapped into 100%, the maximum; * to avoid that p = 1/x is rounded down to 0 when x is very large, since this means accidentally re-entering slow-start indicated by p == 0, the minimum resolution value of p is now returned instead; * a bug in ccid3_hc_rx_getsockopt is fixed: 1/0 was mapped into ~0U. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
2010-09-21dccp ccid-3: remove dead statesGerrit Renker
This patch is thanks to an investigation by Leandro Sales de Melo and his colleagues. They worked out two state diagrams which highlight the fact that the xxx_TERM states in CCID-3/4 are in fact not necessary. And this can be confirmed by in turn looking at the code: the xxx_TERM states are only ever set in ccid3_hc_{rx,tx}_exit(): when CCID-3 sets the state to xxx_TERM, it is at a time where no more processing should be going on, hence it is not necessary to introduce a dedicated exit state - this is already implied by unloading the CCID. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
2010-09-21dccp: Replace magic CCID-specific numbers by symbolic constantsGerrit Renker
The constants DCCPO_{MIN,MAX}_CCID_SPECIFIC are nowhere used in the code, but instead for the CCID-specific options numbers are used. This patch unifies the use of CCID-specific option numbers, by adding symbolic names reflecting the definitions in RFC 4340, 10.3. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
2010-09-21dccp: Add packet type information to CCID-specific option parsingGerrit Renker
This 1. adds packet type information to ccid_hc_{rx,tx}_parse_options(). This is necessary, since table 3 in RFC 4340, 5.8 leaves it to the CCIDs to state which options may (not) appear on what packet type. 2. adds such a check for CCID-3's {Loss Event, Receive} Rate as specified in RFC 4340 8.3 ("Receive Rate options MUST NOT be sent on DCCP-Data packets") and 8.5 ("Loss Event Rate options MUST NOT be sent on DCCP-Data packets"). 3. removes an unused argument `idx' from ccid_hc_{rx,tx}_parse_options(). This is also no longer necessary, since the CCID-specific option-parsing routines are passed every single parameter of the type-length-value option encoding.

2010-09-19bridge : Sanitize skb before it enters the IP stackBandan Das
Related dicussion here : http://lkml.org/lkml/2010/9/3/16 Introduce a function br_parse_ip_options that will audit the skb and possibly refill IP options before a packet enters the IP stack. If no options are present, the function will zero out the skb cb area so that it is not misinterpreted as options by some unsuspecting IP layer routine. If packet consistency fails, drop it.

2010-09-17ethtool, ixgbe: Move RX n-tuple mask fixup to ethtoolBen Hutchings
The ethtool utility does not set masks for flow parameters that are not specified, so if both value and mask are 0 then this must be treated as equivalent to a mask with all bits set. Currently that is done in the only driver that implements RX n-tuple filtering, ixgbe. Move it to the ethtool core. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-09-17netns: keep vlan slaves on master netns moveDavid Lamparter
previously, if a vlan master device was moved from one network namespace to another, all 802.1q and macvlan slaves were deleted. we can use dev->reg_state to figure out whether dev_change_net_namespace is happening, since that won't set dev->reg_state NETREG_UNREGISTERING. so, this changes 8021q and macvlan to ignore NETDEV_UNREGISTER when reg_state is not NETREG_UNREGISTERING.

2010-09-17stmmac: consolidate and tidy-up the COE supportGiuseppe CAVALLARO
The first version of the driver had hard-coded the logic for handling the checksum offloading. This was designed according to the chips included in the STM platforms where: o MAC10/100 supports no COE at all. o GMAC fully supports RX/TX COE. This is not good for other chip configurations where, for example, the mac10/100 supports the tx csum in HW or when the GMAC has no IPC. Thanks to Johannes Stezenbach; he provided me a first draft of this patch that only reviewed the IPC for the GMAC devices. This patch also helps on SPEAr platforms where the MAC10/100 can perform the TX csum in HW. Thanks to Deepak SIKRI for his support on this. In the end, GMAC devices for STM platforms have a bugged Jumbo frame support that needs to have the Tx COE disabled for oversized frames (due to limited buffer sizes). This information is also passed through the driver's platform structure.

This was previously reported as a security issue due to leakage of uninitialized stack memory. Jeff Mahoney pointed out that this is incorrect since the copied data is from a union (rather than a struct).
