2005-10-29[PATCH] bluetooth hidp is broken on s390Al Viro
Bluetooth HIDP selects INPUT and it really needs it to be there - module depends on input core. And input core is never built on s390... Marked as broken on s390, for now; if somebody has better ideas, feel free to fix it and remove dependency...

2005-10-28[MCAST] IPv6: Fix algorithm to compute Querier's Query IntervalYan Zheng
5.1.3. Maximum Response Code The Maximum Response Code field specifies the maximum time allowed before sending a responding Report. The actual time allowed, called the Maximum Response Delay, is represented in units of milliseconds, and is derived from the Maximum Response Code as follows: If Maximum Response Code < 32768, Maximum Response Delay = Maximum Response Code If Maximum Response Code >=32768, Maximum Response Code represents a floating-point value as follows: 0 1 2 3 4 5 6 7 8 9 A B C D E F +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |1| exp | mant | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Maximum Response Delay = (mant | 0x1000) << (exp+3) 5.1.9. QQIC (Querier's Query Interval Code) The Querier's Query Interval Code field specifies the [Query Interval] used by the Querier. The actual interval, called the Querier's Query Interval (QQI), is represented in units of seconds, and is derived from the Querier's Query Interval Code as follows: If QQIC < 128, QQI = QQIC If QQIC >= 128, QQIC represents a floating-point value as follows: 0 1 2 3 4 5 6 7 +-+-+-+-+-+-+-+-+ |1| exp | mant | +-+-+-+-+-+-+-+-+ QQI = (mant | 0x10) << (exp + 3) -- rfc3810 #define MLDV2_QQIC(value) MLDV2_EXP(0x80, 4, 3, value) #define MLDV2_MRC(value) MLDV2_EXP(0x8000, 12, 3, value) Above macro are defined in mcast.c. but 1 << 4 == 0x10 and 1 << 12 == 0x1000.

2005-10-28[IPv4/IPv6]: UFO Scatter-gather approachAnanda Raju
Attached is kernel patch for UDP Fragmentation Offload (UFO) feature. 1. This patch incorporate the review comments by Jeff Garzik. 2. Renamed USO as UFO (UDP Fragmentation Offload) 3. udp sendfile support with UFO This patches uses scatter-gather feature of skb to generate large UDP datagram. Below is a "how-to" on changes required in network device driver to use the UFO interface. UDP Fragmentation Offload (UFO) Interface: ------------------------------------------- UFO is a feature wherein the Linux kernel network stack will offload the IP fragmentation functionality of large UDP datagram to hardware. This will reduce the overhead of stack in fragmenting the large UDP datagram to MTU sized packets 1) Drivers indicate their capability of UFO using dev->features |= NETIF_F_UFO | NETIF_F_HW_CSUM | NETIF_F_SG NETIF_F_HW_CSUM is required for UFO over ipv6. 2) UFO packet will be submitted for transmission using driver xmit routine. UFO packet will have a non-zero value for "skb_shinfo(skb)->ufo_size" skb_shinfo(skb)->ufo_size will indicate the length of data part in each IP fragment going out of the adapter after IP fragmentation by hardware. skb->data will contain MAC/IP/UDP header and skb_shinfo(skb)->frags[] contains the data payload. The skb->ip_summed will be set to CHECKSUM_HW indicating that hardware has to do checksum calculation. Hardware should compute the UDP checksum of complete datagram and also ip header checksum of each fragmented IP packet. For IPV6 the UFO provides the fragment identification-id in skb_shinfo(skb)->ip6_frag_id. The adapter should use this ID for generating IPv6 fragments.

2005-10-27[TCP]: Clear stale pred_flags when snd_wnd changesHerbert Xu
This bug is responsible for causing the infamous "Treason uncloaked" messages that's been popping up everywhere since the printk was added. It has usually been blamed on foreign operating systems. However, some of those reports implicate Linux as both systems are running Linux or the TCP connection is going across the loopback interface. In fact, there really is a bug in the Linux TCP header prediction code that's been there since at least 2.1.8. This bug was tracked down with help from Dale Blount. The effect of this bug ranges from harmless "Treason uncloaked" messages to hung/aborted TCP connections. The details of the bug and fix is as follows. When snd_wnd is updated, we only update pred_flags if tcp_fast_path_check succeeds. When it fails (for example, when our rcvbuf is used up), we will leave pred_flags with an out-of-date snd_wnd value. When the out-of-date pred_flags happens to match the next incoming packet we will again hit the fast path and use the current snd_wnd which will be wrong. In the case of the treason messages, it just happens that the snd_wnd cached in pred_flags is zero while tp->snd_wnd is non-zero. Therefore when a zero-window packet comes in we incorrectly conclude that the window is non-zero. In fact if the peer continues to send us zero-window pure ACKs we will continue making the same mistake. It's only when the peer transmits a zero-window packet with data attached that we get a chance to snap out of it. This is what triggers the treason message at the next retransmit timeout.

2005-10-26[PATCH] kill massive wireless-related log spamJeff Garzik
Although this message is having the intended effect of causing wireless driver maintainers to upgrade their code, I never should have merged this patch in its present form. Leading to tons of bug reports and unhappy users. Some wireless apps poll for statistics regularly, which leads to a printk() every single time they ask for stats. That's a little bit _too_ much of a reminder that the driver is using an old API. Change this to printing out the message once, per kernel boot.

2005-10-26[IPV4]: Kill redundant rcu_dereference on fa_infoHerbert Xu
This patch kills a redundant rcu_dereference on fa->fa_info in fib_trie.c. As this dereference directly follows a list_for_each_entry_rcu line, we have already taken a read barrier with respect to getting an entry from the list. This read barrier guarantees that all values read out of fa are valid. In particular, the contents of structure pointed to by fa->fa_info is initialised before fa->fa_info is actually set (see fn_trie_insert); the setting of fa->fa_info itself is further separated with a write barrier from the insertion of fa into the list. Therefore by taking a read barrier after obtaining fa from the list (which is given by list_for_each_entry_rcu), we can be sure that fa->fa_info contains a valid pointer, as well as the fact that the data pointed to by fa->fa_info is itself valid.

2005-10-23[NEIGH] Fix timer leak in neigh_changeaddrHerbert Xu
neigh_changeaddr attempts to delete neighbour timers without setting nud_state. This doesn't work because the timer may have already fired when we acquire the write lock in neigh_changeaddr. The result is that the timer may keep firing for quite a while until the entry reaches NEIGH_FAILED. It should be setting the nud_state straight away so that if the timer has already fired it can simply exit once we relinquish the lock. In fact, this whole function is simply duplicating the logic in neigh_ifdown which in turn is already doing the right thing when it comes to deleting timers and setting nud_state. So all we have to do is take that code out and put it into a common function and make both neigh_changeaddr and neigh_ifdown call it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2005-10-23[NEIGH] Fix add_timer race in neigh_add_timerHerbert Xu
neigh_add_timer cannot use add_timer unconditionally. The reason is that by the time it has obtained the write lock someone else (e.g., neigh_update) could have already added a new timer. So it should only use mod_timer and deal with its return value accordingly. This bug would have led to rare neighbour cache entry leaks. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
