* [PKT_SCHED]: Fix regression in PSCHED_TADD{,2}.Guillaume Chazarain2006-07-241-12/+6
| | | | | | | | | | | | | | | In PSCHED_TADD and PSCHED_TADD2, if delta is less than tv.tv_usec (so, less than USEC_PER_SEC too) then tv_res will be smaller than tv. The affectation "(tv_res).tv_usec = __delta;" is wrong. The fix is to revert to the original code before 4ee303dfeac6451b402e3d8512723d3a0f861857 and change the 'if' in 'while'. [Shuya MAEDA: "while (__delta >= USEC_PER_SEC){ ... }" instead of "while (__delta > USEC_PER_SEC){ ... }"] Signed-off-by: Guillaume Chazarain <guichaz@yahoo.fr> Signed-off-by: David S.

* [NET]: Prevent multiple qdisc runsHerbert Xu2006-06-191-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Having two or more qdisc_run's contend against each other is bad because it can induce packet reordering if the packets have to be requeued. It appears that this is an unintended consequence of relinquinshing the queue lock while transmitting. That in turn is needed for devices that spend a lot of time in their transmit routine. There are no advantages to be had as devices with queues are inherently single-threaded (the loopback device is not but then it doesn't have a queue). Even if you were to add a queue to a parallel virtual device (e.g., bolt a tbf filter in front of an ipip tunnel device), you would still want to process the queue in sequence to ensure that the packets are ordered correctly. The solution here is to steal a bit from net_device to prevent this. BTW, as qdisc_restart is no longer used by anyone as a module inside the kernel (IIRC it used to with netif_wake_queue), I have not exported the new __qdisc_run function.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
