sctp: rename sp strm_interleave to ep intl_enable

2019-07-09T03:16:25+00:00

Like other endpoint features, strm_interleave should be moved to sctp_endpoint and renamed to intl_enable. Signed-off-by: Xin Long Signed-off-by: David S. Miller

sctp: rename asoc intl_enable to asoc peer.intl_capable

2019-07-09T03:16:25+00:00

To keep consistent with other asoc features, we move intl_enable to peer.intl_capable in asoc. Signed-off-by: Xin Long Signed-off-by: David S. Miller

sctp: remove prsctp_enable from asoc

2019-07-09T03:16:24+00:00

Like reconf_enable, prsctp_enable should also be removed from asoc, as asoc->peer.prsctp_capable has taken its job. Signed-off-by: Xin Long Signed-off-by: David S. Miller

sctp: remove reconf_enable from asoc

2019-07-09T03:16:24+00:00

asoc's reconf support is actually decided by the 4-shakehand negotiation, not something that users can set by sockopt. asoc->peer.reconf_capable is working for this. So remove it from asoc. Signed-off-by: Xin Long Signed-off-by: David S. Miller

sctp: convert to genradix

2019-03-12T17:04:02+00:00

This also makes sctp_stream_alloc_(out|in) saner, in that they no longer allocate new flex_arrays/genradixes, they just preallocate more elements. This code does however have a suspicious lack of locking.

sctp: add SCTP_FUTURE_ASOC and SCTP_CURRENT_ASSOC for SCTP_STREAM_SCHEDULER sockopt

2019-01-30T08:44:08+00:00

Check with SCTP_ALL_ASSOC instead in sctp_setsockopt_scheduler and check with SCTP_FUTURE_ASSOC instead in sctp_getsockopt_scheduler, it's compatible with 0. SCTP_CURRENT_ASSOC is supported for SCTP_STREAM_SCHEDULER in this patch. It also adds default_ss in sctp_sock to support SCTP_FUTURE_ASSOC. Signed-off-by: Xin Long Signed-off-by: David S. Miller

sctp: add SCTP_FUTURE_ASSOC for SCTP_PEER_ADDR_THLDS sockopt

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

2018-12-10T05:43:31+00:00

Several conflicts, seemingly all over the place. I used Stephen Rothwell's sample resolutions for many of these, if not just to double check my own work, so definitely the credit largely goes to him. The NFP conflict consisted of a bug fix (moving operations past the rhashtable operation) while chaning the initial argument in the function call in the moved code. The net/dsa/master.c conflict had to do with a bug fix intermixing of making dsa_master_set_mtu() static with the fixing of the tagging attribute location. cls_flower had a conflict because the dup reject fix from Or overlapped with the addition of port range classifiction. __set_phy_supported()'s conflict was relatively easy to resolve because Andrew fixed it in both trees, so it was just a matter of taking the net-next copy. Or at least I think it was :-) Joe Stringer's fix to the handling of netns id 0 in bpf_sk_lookup() intermixed with changes on how the sdif and caller_net are calculated in these code paths in net-next. The remaining BPF conflicts were largely about the addition of the __bpf_md_ptr stuff in 'net' overlapping with adjustments and additions to the relevant data structure where the MD pointer macros are used.

sctp: kfree_rcu asoc

2018-12-03T23:54:41+00:00

In sctp_hash_transport/sctp_epaddr_lookup_transport, it dereferences a transport's asoc under rcu_read_lock while asoc is freed not after a grace period, which leads to a use-after-free panic. This patch fixes it by calling kfree_rcu to make asoc be freed after a grace period. Note that only the asoc's memory is delayed to free in the patch, it won't cause sk to linger longer. Thanks Neil and Marcelo to make this clear.
