2007-11-14[TCP] FRTO: Clear frto_highmark only after process_frto that uses itIlpo Järvinen
I broke this in commit 3de96471bd7fb76406e975ef6387abe3a0698149: [TCP]: Wrap-safed reordering detection FRTO check tcp_process_frto should always see a valid frto_highmark. An invalid frto_highmark (zero) is very likely what ultimately caused a seqno compare in tcp_frto_enter_loss to do the wrong leading to the LOST-bit leak. Having LOST-bits integry ensured like done after commit 23aeeec365dcf8bc87fae44c533e50d0bb4f23cc: [TCP] FRTO: Plug potential LOST-bit leak won't hurt.

2007-11-14[NET]: Remove notifier block from chain when register_netdevice_notifier failsPavel Emelyanov
Commit fcc5a03ac42564e9e255c1134dda47442289e466: [NET]: Allow netdev REGISTER/CHANGENAME events to fail makes the register_netdevice_notifier() handle the error from the NETDEV_REGISTER event, sent to the registering block. The bad news is that in this case the notifier block is not removed from the list, but the error is returned to the caller. In case the caller is in module init function and handles this error this can abort the module loading. The notifier block will be then removed from the kernel, but will be left in the list. Oops :( I think that the notifier block should be removed from the chain in case of error, regardless whether this error is handled by the caller or not. In the worst case (the error is _not_ handled) module will not receive the events any longer.

2007-11-14[TCP]: Make sure write_queue_from does not begin with NULL ptrIlpo Järvinen
NULL ptr can be returned from tcp_write_queue_head to cached_skb and then assigned to skb if packets_out was zero. Without this, system is vulnerable to a carefully crafted ACKs which obviously is remotely triggerable. Besides, there's very little that needs to be done in sacktag if there weren't any packets outstanding, just skipping the rest doesn't hurt.

2007-11-14[TCP]: Fix size calculation in sk_stream_alloc_pskbHerbert Xu
We round up the header size in sk_stream_alloc_pskb so that TSO packets get zero tail room. Unfortunately this rounding up is not coordinated with the select_size() function used by TCP to calculate the second parameter of sk_stream_alloc_pskb. As a result, we may allocate more than a page of data in the non-TSO case when exactly one page is desired. In fact, rounding up the head room is detrimental in the non-TSO case because it makes memory that would otherwise be available to the payload head room. TSO doesn't need this either, all it wants is the guarantee that there is no tail room. So this patch fixes this by adjusting the skb_reserve call so that exactly the requested amount (which all callers have calculated in a precise way) is made available as tail room.

All 32 bits machines but i386 dont have CONFIG_KTIME_SCALAR. On these machines, ktime.tv64 is more than 4 times the (correct) result given by ktime_to_ns() Again on these machines, using ktime_get_real().tv64 >> 6 give a 32bits rollover every 64 seconds, which is not wanted (less than the 120 s MSL) Using ktime_to_ns() is the portable way to get nsecs from a ktime, and have correct code.

2007-11-13[TCP] FRTO: Limit snd_cwnd if TCP was application limitedIlpo Järvinen
Otherwise TCP might violate packet ordering principles that FRTO is based on. If conventional recovery path is chosen, this won't be significant at all. In practice, any small enough value will be sufficient to provide proper operation for FRTO, yet other users of snd_cwnd might benefit from a "close enough" value. FRTO's formula is now equal to what tcp_enter_cwr() uses. FRTO used to check application limitedness a bit differently but I changed that in commit 575ee7140dabe9b9c4f66f4f867039b97e548867 and as a result checking for application limitedness became completely non-existing.

2007-11-13[PKT_SCHED]: Check subqueue status before calling hard_start_xmitPeter P Waskiewicz Jr
The only qdiscs that check subqueue state before dequeue'ing are PRIO and RR. The other qdiscs, including the default pfifo_fast qdisc, will allow traffic bound for subqueue 0 through to hard_start_xmit. The check for netif_queue_stopped() is done above in pkt_sched.h, so it is unnecessary for qdisc_restart(). However, if the underlying driver is multiqueue capable, and only sets queue states on subqueues, this will allow packets to enter the driver when it's currently unable to process packets, resulting in expensive requeues and driver entries. This patch re-adds the check for the subqueue status before calling hard_start_xmit, so we can try and avoid the driver entry when the queues are stopped.

2007-11-13Revert "ext2/ext3/ext4: add block bitmap validation"Linus Torvalds
This reverts commit 7c9e69faa28027913ee059c285a5ea8382e24b5d, fixing up conflicts in fs/ext4/balloc.c manually. The cost of doing the bitmap validation on each lookup - even when the bitmap is cached - is absolutely prohibitive. We could, and probably should, do it only when adding the bitmap to the buffer cache. However, right now we are better off just reverting it. Peter Zijlstra measured the cost of this extra validation as a 85% decrease in cached iozone, and while I had a patch that took it down to just 17% by not being _quite_ so stupid in the validation, it was still a big slowdown that could have been avoided by just doing it right.

2007-11-13[POWERPC] Avoid unpaired stwcx. on some processorsBecky Bruce
The context switch code in the kernel issues a dummy stwcx. to clear the reservation, as recommended by the architecture. However, some processors can have issues if this stwcx to address A occurs while the reservation is already held to a different address B. To avoid this problem, the dummy stwcx. needs to be paired with a dummy lwarx to the same address. This adds the dummy lwarx, and creates a cpu feature bit to indicate which cpus are affected.

2007-11-12[TG3]: Fix nvram selftest failuresMatt Carlson
Newer devices contain bootcode in the chip's private ROM area. This bootcode is called selfboot. Selfboot can be patched in the device's NVRAM and the patches can have several formats. In one particular format, the checksum calculation needs to be slightly modified. This patch adjusts the NVRAM test code for that case, and add support for the missing formats.
