net/802/mrp: fix possible race condition when calling mrp_pdu_queue()

2013-04-12T19:10:48Z

(Adapted from a very similar change to net/802/garp.c by Cong Wang.) mrp_pdu_queue() should ways be called with the applicant spin lock. mrp_uninit_applicant() only holds the rtnl lock which is not enough; a race is possible because mrp_rcv() is called in BH context: mrp_rcv() |->mrp_pdu_parse_msg() |->mrp_pdu_parse_vecattr() |->mrp_pdu_parse_vecattr_event() |-> mrp_attr_event() |-> mrp_pdu_append_vecattr_event() |-> mrp_pdu_queue() Cc: Cong Wang Cc: Eric Dumazet Signed-off-by: David Ward Acked-by: Cong Wang Signed-off-by: David S.

tokenring: delete all remaining driver support

2012-05-16T00:23:16Z

This represents the mass deletion of the of the tokenring support. It gets rid of: - the net/tr.c which the drivers depended on - the drivers/net component - the Kbuild infrastructure around it - any tokenring related CONFIG_ settings in any defconfigs - the tokenring headers in the include/linux dir - the firmware associated with the tokenring drivers. - any associated token ring documentation.

net: delete all instances of special processing for token ring

2012-05-16T00:14:35Z

We are going to delete the Token ring support. This removes any special processing in the core networking for token ring, (aside from net/tr.c itself), leaving the drivers and remaining tokenring support present but inert. The mass removal of the drivers and net/tr.c will be in a separate commit, so that the history of these files that we still care about won't have the giant deletion tied into their history.

802: Convert compare_ether_addr to ether_addr_equal

2012-05-10T00:49:17Z

Use the new bool function ether_addr_equal to add some clarity and reduce the likelihood for misuse of compare_ether_addr for sorting. Done via cocci script: $ cat compare_ether_addr.cocci @@ expression a,b; @@ - !compare_ether_addr(a, b) + ether_addr_equal(a, b) @@ expression a,b; @@ - compare_ether_addr(a, b) + !ether_addr_equal(a, b) @@ expression a,b; @@ - !ether_addr_equal(a, b) == 0 + ether_addr_equal(a, b) @@ expression a,b; @@ - !ether_addr_equal(a, b) != 0 + !ether_addr_equal(a, b) @@ expression a,b; @@ - ether_addr_equal(a, b) == 0 + !ether_addr_equal(a, b) @@ expression a,b; @@ - ether_addr_equal(a, b) != 0 + ether_addr_equal(a, b) @@ expression a,b; @@ - !!ether_addr_equal(a, b) + ether_addr_equal(a, b) Signed-off-by: Joe Perches Signed-off-by: David S.

net: Convert all sysctl registrations to register_net_sysctl

2012-04-21T01:22:30Z

This results in code with less boiler plate that is a bit easier to read. Additionally stops us from using compatibility code in the sysctl core, hastening the day when the compatibility code can be removed. Signed-off-by: Eric W. Biederman Acked-by: Pavel Emelyanov Signed-off-by: David S. Miller

net: Move all of the network sysctls without a namespace into init_net.

2012-04-21T01:21:17Z

This makes it clearer which sysctls are relative to your current network namespace. This makes it a little less error prone by not exposing sysctls for the initial network namespace in other namespaces. This is the same way we handle all of our other network interfaces to userspace and I can't honestly remember why we didn't do this for sysctls right from the start. Signed-off-by: Eric W.

net/garp: fix GID rbtree ordering

2012-04-13T17:10:33Z

The comparison operators were backwards in both garp_attr_lookup and garp_attr_create, so the entire GID rbtree was in reverse order. (There was no practical side effect to this though, except that PDUs were sent with attributes listed in reverse order, which is still valid by the protocol. This change is only for clarity.)
