RED is useful for high throughput routers, I doubt many linux machines act as such devices. I was considering adding Adaptative RED (Sally Floyd, Ramakrishna Gummadi, Scott Shender), August 2001 In this version, maxp is dynamic (from 1% to 50%), and user only have to setup min_th (target average queue size) (max_th and wq (burst in linux RED) are automatically setup) By the way it seems we have a small bug in red_change() if (skb_queue_empty(&sch->q)) red_end_of_idle_period(&q->parms); First, if queue is empty, we should call red_start_of_idle_period(&q->parms); Second, since we dont use anymore sch->q, but q->qdisc, the test is meaningless. Oh well... [PATCH] sch_red: fix red_change() Now RED is classful, we must check q->qdisc->q.qlen, and if queue is empty, we start an idle period, not end it.

When in user-stp mode, bridge master do not follow state of its slaves, so after the following sequence of events it can stuck forever in no-carrier state: 1) turn stp off 2) put all slaves down - master device will follow their state and also go in no-carrier state 3) turn stp on with bridge-stp script returning 0 (go to the user-stp mode) Now bridge master won't follow slaves' state and will never reach running state. This patch solves the problem by making user-stp and kernel-stp behavior similar regarding master following slaves' states.

Since commit a4a710c4 (pkt_sched: Change PSCHED_SHIFT from 10 to 6) it seems RED/GRED are broken. red_calc_qavg_from_idle_time() computes a delay in us units, but this delay is now 16 times bigger than real delay, so the final qavg result smaller than expected.

A recent fix to the the NetLabel code caused build problem with configurations that did not have IPv6 enabled; see below: netlabel_kapi.c: In function 'netlbl_cfg_unlbl_map_add': netlabel_kapi.c:165:4: error: implicit declaration of function 'netlbl_af6list_add' This patch fixes this problem by making the IPv6 specific code conditional on the IPv6 configuration flags as we done in the rest of NetLabel and the network stack as a whole. We have to move some variable declarations around as a result so things may not be quite as pretty, but at least it builds cleanly now. Some additional IPv6 conditionals were added to the NetLabel code as well for the sake of consistency.

The check from commit 30c2235c is incomplete and cannot prevent cases like key_len = 0x80000000 (INT_MAX + 1). In that case, the left-hand side of the check (INT_MAX - key_len), which is unsigned, becomes 0xffffffff (UINT_MAX) and bypasses the check. However this shouldn't be a security issue. The function is called from the following two code paths: 1) setsockopt() 2) sctp_auth_asoc_set_secret() In case (1), sca_keylength is never going to exceed 65535 since it's bounded by a u16 from the user API. As such, the key length will never overflow. In case (2), sca_keylength is computed based on the user key (1 short) and 2 * key_vector (3 shorts) for a total of 7 * USHRT_MAX, which still will not overflow. In other words, this overflow check is not really necessary. Just make it more correct.

由 Emmanuel Grumbach 提交于
When a packet is supposed to sent be as an a-MPDU, mac80211 sets IEEE80211_TX_CTL_AMPDU to let the driver know. On the other hand, mac80211 configures the driver for aggregration with the ampdu_action callback. There is race between these two mechanisms since the following scenario can occur when the BA agreement is torn down: Tx softIRQ drv configuration ========== ================= check OPERATIONAL bit Set the TX_CTL_AMPDU bit in the packet clear OPERATIONAL bit stop Tx AGG Pass Tx packet to the driver. In that case the driver would get a packet with TX_CTL_AMPDU set although it has already been notified that the BA session has been torn down. To fix this, we need to synchronize all the Qdisc activity after we cleared the OPERATIONAL bit. After that step, all the following packets will be buffered until the driver reports it is ready to get new packets for this RA / TID. This buffering allows not to run into another race that would send packets with TX_CTL_AMPDU unset while the driver hasn't been requested to tear down the BA session yet. This race occurs in practice and iwlwifi complains with a WARN_ON when it happens.

As inetpeer is not yet namespace aware, this patch adds a shared redirect_genid, and a per inetpeer redirect_genid. This might be changed later if inetpeer becomes ns aware. Cache information for one inerpeer is valid as long as its redirect_genid has the same value than global redirect_genid.

Reason is that the transformer bundle attached to the dst entry is now in STATE_DEAD and thus xfrm_output_one() drops all packets (XfrmOutStateExpired increases).

The pmtu informations on the inetpeer are visible for output and input routes. On packet forwarding, we might propagate a learned pmtu to the sender. As we update the pmtu informations of the inetpeer on demand, the original sender of the forwarded packets might never notice when the pmtu to that inetpeer increases. So use the mtu of the outgoing device on packet forwarding instead of the pmtu to the final destination. Signed-off-by: NSteffen Klassert <steffen.klassert@secunet.com> Signed-off-by: NDavid S.

We move all mtu handling from dst_mtu() down to the protocol layer. So each protocol can implement the mtu handling in a different manner. Signed-off-by: NSteffen Klassert <steffen.klassert@secunet.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

We plan to invoke the dst_opt->default_mtu() method unconditioally from dst_mtu(). So rename the method to dst_opt->mtu() to match the name with the new meaning. Signed-off-by: NSteffen Klassert <steffen.klassert@secunet.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

As it is, we return null as the default mtu of blackhole routes. This may lead to a propagation of a bogus pmtu if the default_mtu method of a blackhole route is invoked. So return dst->dev->mtu as the default mtu instead. Signed-off-by: NSteffen Klassert <steffen.klassert@secunet.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This was copy and pasted from the IPv4 code. We're calling the ip4 version of that function and map4 is NULL. Signed-off-by: NDan Carpenter <dan.carpenter@oracle.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
