Userspace using ioctl does not know about the difference between the initial setup phase and a controller being present.

To determine that we are the initiators it's therefore best to simply change the flag value when we know we're sending the first SMP PDU. Clearing the flag when receiving a Pairing Request is not correct since the request may be a response to a previous Security Request from us (for which we would already have correctly set the flag). Same goes for receiving a Security Request which may be coming after us already starting pairing by sending a Pairing Request.

It also introduces some sane minimums for low_thresh as it shouldn't be able to drop below 0 (or > high_thresh in the unsigned case), and overall low_thresh should not ever be above high_thresh, so we make the following relations for a namespace: init_net: high_thresh - max(not capped), min(init_net low_thresh) low_thresh - max(init_net high_thresh), min (0) all other namespaces: high_thresh = max(init_net high_thresh), min(namespace's low_thresh) low_thresh = max(namespace's high_thresh), min(0) The major issue with having low_thresh > high_thresh is that we'll schedule eviction but never evict anything and thus rely only on the timers.

This happens in softirq/packet processing context. This has two drawbacks: 1) processors might evict a queue that was about to be completed by another cpu, because they will compete wrt. resource usage and resource reclaim. 2) LRU list maintenance is expensive. But when constantly overloaded, even the 'least recently used' element is recent, so removing 'lru' queue first is not 'fairer' than removing any other fragment queue. This moves eviction out of the fast path: When the low threshold is reached, a work queue is scheduled which then iterates over the table and removes the queues that exceed the memory limits of the namespace. It sets a new flag called INET_FRAG_EVICTED on the evicted queues so the proper counters will get incremented when the queue is forcefully expired. When the high threshold is reached, no more fragment queues are created until we're below the limit again. The LRU list is now unused and will be removed in a followup patch.

However its use, within the Open vSwitch code-base is limited: only a single user-space action is ever nested. A consequence of the current implementation of sample actions is that depending on weather the sample action executed (due to its probability) any side-effects of nested actions may or may not be present before executing subsequent actions. This has the potential to complicate verification of valid actions by the (kernel) datapath. And indeed adding support for push and pop MPLS actions inside sample actions is one case where such case. In order to allow all supported actions to be continue to be nested inside sample actions without the potential need for complex verification code this patch changes the implementation of the sample action in the kernel datapath so that sample actions are more like a function call and any side effects of nested actions are not present when executing subsequent actions. With the above in mind the motivation for this change is twofold: * To contain side-effects the sample action in the hope of making it easier to deal with in the future and; * To avoid some rather complex verification code introduced in the MPLS datapath patch.

The raw(7) man page states: "In addition, all ip(7) IPPROTO_IP socket options valid for datagram sockets are supported", which implies these ioctls should work on raw sockets. To fix this, add a call to ip_mc_sf_allow on raw sockets. This should not break any existing code, since the current position of not calling ip_mc_sf_filter makes it behave as if neither the IP_MULTICAST_ALL nor the IP_MSFILTER ioctl had been called. Adding the call to ip_mc_sf_allow will therefore maintain the current behaviour so long as IP_MULTICAST_ALL and IP_MSFILTER ioctls are not called. Any code that currently is calling IP_MULTICAST_ALL or IP_MSFILTER ioctls on raw sockets presumably is wanting the filter to be applied, although no filtering will currently be occurring.

Separate out each into its own 'if (test) return SCTP_XMIT_OK' so that the reasons can be individually described. Also return directly with SCTP_XMIT_RWND_FULL. Delete the now-unused 'retval' variable and 'finish' label from sctp_packet_can_append_data().

They are caused by quiescing a path even though it has been already severed by peer. For IUCV transport shutdown() consists of 2 steps: (1) sending the shutdown message to peer (2) quiescing the iucv path If the iucv path between these 2 steps is severed due to peer closing the path, the quiesce step is no longer needed.

The nflog infrastructure superseded this almost 9 years ago, time to get rid of this code. 4) Replace the list of loggers by an array now that we can only have two possible non-overlapping logger flavours, ie. kernel ring buffer and netlink logging. 5) Move Eric Dumazet's log buffer code to nf_log to reuse it from all of the supported per-family loggers. 6) Consolidate nf_log_packet() as an unified interface for packet logging. After this patch, if the struct nf_loginfo is available, it explicitly selects the logger that is used. 7) Move ip and ip6 logging code from xt_LOG to the corresponding per-family loggers. Thus, x_tables and nf_tables share the same code for packet logging. 8) Add generic ARP packet logger, which is used by nf_tables. The format aims to be consistent with the output of xt_LOG. 9) Add generic bridge packet logger. Again, this is used by nf_tables and it routes the packets to the real family loggers. As a result, we get consistent logging format for the bridge family. The ebt_log logging code has been intentionally left in place not to break backward compatibility since the logging output differs from xt_LOG. 10) Update nft_log to explicitly request the required family logger when needed. 11) Finish nft_log so it supports arp, ip, ip6, bridge and inet families. Allowing selection between netlink and kernel buffer ring logging. 12) Several fixes coming after the netfilter core logging changes spotted by robots. 13) Use IS_ENABLED() macros whenever possible in the netfilter tree, from Duan Jiong. 14) Removal of a couple of unnecessary branch before kfree, from Fabian Frederick. ==================== Signed-off-by: David S.
