pkt_sched: sch_api: Move away from NLMSG_NEW().

2012-06-27T04:54:15Z

And use nlmsg_data() while we're here too, as well as remove a useless cast. Signed-off-by: David S. Miller

net: Convert net_ratelimit uses to net__ratelimited

2012-05-15T17:45:03Z

Standardize the net core ratelimited logging functions. Coalesce formats, align arguments. Change a printk then vprintk sequence to use printf extension %pV. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

pkt_sched: Stop using NLA_PUT*().

2012-04-01T22:11:37Z

These macros contain a hidden goto, and are thus extremely error prone and make code hard to audit. Signed-off-by: David S. Miller

net_sched: qdisc_alloc_handle() can be too slow

2012-01-03T18:03:20Z

When trying to allocate ~32768 qdiscs using autohandle mechanism, we can fill the space managed by kernel (handles in [8000-FFFF]:0000 range) But O(N^2) qdisc_alloc_handle() loops 0x10000 times instead of 0x8000 time tc add qdisc add dev eth0 parent 10:7fff pfifo limit 10 RTNETLINK answers: Cannot allocate memory real 1m54.826s user 0m0.000s sys 0m0.004s INFO: rcu_sched_state detected stall on CPU 0 (t=60000 jiffies) Half number of loops, and add a cond_resched() call. We hold rtnl at this point. Signed-off-by: Eric Dumazet CC: Dave Taht Signed-off-by: David S. Miller

rtnetlink: Compute and store minimum ifinfo dump size

2011-06-10T03:38:07Z

The message size allocated for rtnl ifinfo dumps was limited to a single page. This is not enough for additional interface info available with devices that support SR-IOV and caused a bug in which VF info would not be displayed if more than approximately 40 VFs were created per interface. Implement a new function pointer for the rtnl_register service that will calculate the amount of data required for the ifinfo dump and allocate enough data to satisfy the request.

pkt_sched: Kill set but unused variable 'protocol' in tc_classify()

I checked the history and this has been like this since the beginning of time. Signed-off-by: David S. Miller

net_sched: RCU conversion of stab

2011-01-21T00:59:32Z

This patch converts stab qdisc management to RCU, so that we can perform the qdisc_calculate_pkt_len() call before getting qdisc lock. This shortens the lock's held time in __dev_xmit_skb(). This permits more qdiscs to get TCQ_F_CAN_BYPASS status, avoiding lot of cache misses and so reducing latencies.

net_sched: move TCQ_F_THROTTLED flag

2011-01-21T00:59:32Z

In commit 371121057607e (net: QDISC_STATE_RUNNING dont need atomic bit ops) I moved QDISC_STATE_RUNNING flag to __state container, located in the cache line containing qdisc lock and often dirtied fields. I now move TCQ_F_THROTTLED bit too, so that we let first cache line read mostly, and shared by all cpus. This should speedup HTB/CBQ for example. Not using test_bit()/__clear_bit()/__test_and_set_bit allows to use an "unsigned int" for __state container, reducing by 8 bytes Qdisc size. Introduce helpers to hide implementation details.
