| * openvswitch: Fix multipart datapath dumps.Ben Pfaff2012-01-171-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | The logic to split up the list of datapaths into multiple Netlink messages was simply wrong, causing the list to be terminated after the first part. Only about the first 50 datapaths would be dumped. This fixes the problem.

| * net: WARN if skb_checksum_help() is called on skb requiring segmentationBen Hutchings2012-01-171-12/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | skb_checksum_help() has never done anything useful with skbs that require segmentation. Setting skb->ip_summed = CHECKSUM_NONE makes them invalid and provokes a later WARNing in skb_gso_segment(). Passing such an skb to skb_checksum_help() indicates a bug, so we should warn about it immediately. Move the warning from skb_gso_segment() into a shared function, and add gso_type and gso_size to it. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We may leak the 'fwd_skb' we skb_copy() in ieee80211_rx_h_mesh_fwding() if we take the 'else' branch in the 'if' statement just below. If we take that branch we'll end up returning from the function and since we've not assigned 'fwd_skb' to anything at that point, we leak it when the variable goes out of scope. The simple fix seems to be to just kfree_skb(fwd_skb); just before we return. That is what this patch does. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: John W.

Similarly, when it unauthorizes a station that is associated, nothing happens. However, when it unauthorizes a station that isn't even associated yet, we erroneously try to move the station to associated. This seems to happen occasionally as a result of a race when wpa_supplicant attempts to unauthorize the port in managed mode. Particularly with my new patches to keep stations, it can then move a station into ASSOCIATED state before we have really associated, which is really confusing.

After this patch, the tree remains just like before patch bc01bef, that initially added the preliminary infrastructure. I decided to partially revert this patch because the approach that I proposed to resolve this problem is broken in NAT setups. Moreover, a new infrastructure will be submitted for the 3.3.x development cycle that resolve the existing issues while providing a neat solution. Since nobody has been seriously using this infrastructure in user-space, the removal of this feature should affect any know FOSS project (to my knowledge).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was unexpected behavior (at least for me)--why would you want configuration settings automatically lost on nfsd restart?

| * | | svcrpc: fix double-free on shutdown of nfsd after changing pool modeJ. Bruce Fields2012-01-051-0/+3

They *are* initialized to zero on kernel startup. So as long as you use only SVC_POOL_GLOBAL (the default), this will never be a problem. You're also OK if you only ever use SVC_POOL_PERCPU or SVC_POOL_PERNODE. However, the following sequence events leads to a double-free: 1. set SVC_POOL_PERCPU or SVC_POOL_PERNODE 2. start nfsd: both fields are initialized. 3. shutdown nfsd: both fields are freed. 4. set SVC_POOL_GLOBAL 5. start nfsd: the fields are left untouched. 6. shutdown nfsd: now we try to free them again. Step 4 is actually unnecessary, since (for some bizarre reason), nfsd automatically resets the pool mode to SVC_POOL_GLOBAL on shutdown. Cc: stable@kernel.org Signed-off-by: J.

In normal operation a server thread will later come along and take the xprt off that list. On shutdown, after all the threads have exited, we instead manually walk the sv_tempsocks and sv_permsocks lists to find all the xprt's and delete them. So the sp_sockets lists don't really matter any more. As a result, we've mostly just ignored them and hoped they would go away. Which has gotten us into trouble; witness for example ebc63e531cc6 "svcrpc: fix list-corrupting race on nfsd shutdown", the result of Ben Greear noticing that a still-running svc_xprt_enqueue() could re-add an xprt to an sp_sockets list just before it was deleted. The fix was to remove it from the list at the end of svc_delete_xprt(). But that only made corruption less likely--I can see nothing that prevents a svc_xprt_enqueue() from adding another xprt to the list at the same moment that we're removing this xprt from the list. In fact, despite the earlier xpo_detach(), I don't even see what guarantees that svc_xprt_enqueue() couldn't still be running on this xprt. So, instead, note that svc_xprt_enqueue() essentially does: lock sp_lock if XPT_BUSY unset add to sp_sockets unlock sp_lock So, if we do: set XPT_BUSY on every xprt. Empty every sp_sockets list, under the sp_socks locks. Then we're left knowing that the sp_sockets lists are all empty and will stay that way, since any svc_xprt_enqueue() will check XPT_BUSY under the sp_lock and see it set. And *then* we can continue deleting the xprt's. (Thanks to Jeff Layton for being correctly suspicious of this code....)

Traditional SFQ limits count of packets, while RED permits to also control number of bytes per flow, and adds ECN capability as well. 1) We dont handle the idle time management in this RED implementation, since each 'new flow' begins with a null qavg. We really want to address backlogged flows. 2) if headdrop is selected, we try to ecn mark first packet instead of currently enqueued packet. This gives faster feedback for tcp flows compared to traditional RED [ marking the last packet in queue ] Example of use : tc qdisc add dev $DEV parent 1:1 handle 10: est 1sec 4sec sfq \ limit 3000 headdrop flows 512 divisor 16384 \ redflowlimit 100000 min 8000 max 60000 probability 0.20 ecn qdisc sfq 10: parent 1:1 limit 3000p quantum 1514b depth 127 headdrop flows 512/16384 divisor 16384 ewma 6 min 8000b max 60000b probability 0.2 ecn prob_mark 0 prob_mark_head 4876 prob_drop 6131 forced_mark 0 forced_mark_head 0 forced_drop 0 Sent 1175211782 bytes 777537 pkt (dropped 6131, overlimits 11007 requeues 0) rate 99483Kbit 8219pps backlog 689392b 456p requeues 0 In this test, with 64 netperf TCP_STREAM sessions, 50% using ECN enabled flows, we can see number of packets CE marked is smaller than number of drops (for non ECN flows) If same test is run, without RED, we can check backlog is much bigger. qdisc sfq 10: parent 1:1 limit 3000p quantum 1514b depth 127 headdrop flows 512/16384 divisor 16384 Sent 1148683617 bytes 795006 pkt (dropped 0, overlimits 0 requeues 0) rate 98429Kbit 8521pps backlog 1221290b 841p requeues 0 Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Stephen Hemminger <shemminger@vyatta.com> CC: Dave Taht <dave.taht@gmail.com> Tested-by: Dave Taht <dave.taht@gmail.com> Signed-off-by: David S.

Otherwise we assume it was never incremented. But what the code actually does is test for RES_USAGE instead of RES_LIMIT. Usage being different than maximum is likely to be true most of the time. The effect of this is that the key must become negative, and since the jump_label test says: !!atomic_read(&key->enabled); we'll have jump_labels still on when no one else is using this functionality.

This happen with rt73usb and rt61pci at least. Before the commit we always check rx->key against NULL, so I assume fix should be done in mac80211 (also mic_fail path has similar check).

Fix by parsing only the current flags in the old flags attribute -- new applications and new flags should use (and will now require) the new flags attribute where the mask is given by the application.
