The goal of this patch is to prepare the removal of the iflink field. It introduces a new ndo function, which will be implemented by virtual interfaces. There is no functional change into this patch. All readers of iflink field now call dev_get_iflink(). Signed-off-by: NNicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Oliver Hartkopp 提交于
The CAN_RAW socket can set multiple CAN identifier specific filters that lead to multiple filters in the af_can.c filter processing. These filters are indenpendent from each other which leads to logical OR'ed filters when applied. This socket option joines the given CAN filters in the way that only CAN frames are passed to user space that matched *all* given CAN filters. The semantic for the applied filters is therefore changed to a logical AND. This is useful especially when the filterset is a combination of filters where the CAN_INV_FILTER flag is set in order to notch single CAN IDs or CAN ID ranges from the incoming traffic. As the raw_rcv() function is executed from NET_RX softirq the introduced variables are implemented as per-CPU variables to avoid extensive locking at CAN frame reception time.

These filters are indenpendent from each other which leads to logical OR'ed filters when applied. This patch makes sure that every CAN frame which is filtered for a specific socket is only delivered once to the user space.

IP addresses are often stored in netlink attributes. Add generic functions to do that.

While fixing a recent issue I noticed that we are doing some unnecessary work inside the loop for ip_fib_net_exit. As such I am pulling out the initialization to NULL for the locally stored fib_local, fib_main, and fib_default. In addition I am restoring the original code for flushing the table as there is no need to split up the fib_table_flush and hlist_del work since the code for packing the tnodes with multiple key vectors was dropped.

Commit 8ade538b ("mac80111: Add BIP-GMAC-128 and BIP-GMAC-256 ciphers") had the success return in incorrect place before the crypto_aead_setauthsize() call which practically ended up skipping that call unconditionally. The missing call did not actually change any functionality since GMAC_MIC_LEN (16) is identical to the maxauthsize in gcm(aes) and as such, the default value used for the authsize parameter.

This will expose in /sys whether the ifname of a device is set by userspace or generated by the kernel. The latter kind (wlanX, etc) is not deterministic, so userspace needs to rename these devices to names that are guaranteed to stay the same between reboots. The former, however should never be renamed, so userspace needs to be able to reliably tell the difference.

If a peer or some local agent (rate control, ...) decides to start an aggregation session but doesn't support HT (which also implies QoS), reject it. This is mostly a corner case as such peers normally won't try to use block-ack sessions and rate control wouldn't start them, but technically QoS stations could request it according to the spec. However, since drivers don't really support such non-HT sessions it's better to reject them. Also, while at it, move the tracing for TX sessions earlier so it captures the error cases as well.

The rate control locking caused a potential deadlock here due to the locks being acquired in different orders, so that change cannot yet be applied. However, there's no fundamental reason for this code to hold the sta->lock while transmitting frames. Clearly it's better not to hold the lock for longer periods of time, which can happen here since we call all the way down to the driver. Change the code a bit to not hold it while doing that.

A message sent to a node after a successful name table lookup may still find that the destination socket has disappeared, because distribution of name table updates is non-atomic. If so, the message will be rejected back to the sender with error code TIPC_ERR_NO_PORT. If the source socket of the message has disappeared in the meantime, the message should be dropped. However, in the currrent code, the message will instead be subject to an unwanted tertiary lookup, because the function tipc_msg_lookup_dest() doesn't check if there is an error code present in the message before performing the lookup. In the worst case, the message may now find the old destination again, and be redirected once more, instead of being dropped directly as it should be. A second bug in this function is that the "prev_node" field in the message is not updated after successful lookup, something that may have unpredictable consequences. The problems arising from those bugs occur very infrequently. The third change in this function; the test on msg_reroute_msg_cnt() is purely cosmetic, reflecting that the returned value never can be negative. This commit corrects the two bugs described above.
