2009-09-03ipv6: Fix tcp_v6_send_response(): it didn't set skb transport headerCosmin Ratiu
Here is a patch which fixes an issue observed when using TCP over IPv6 and AH from IPsec. When a connection gets closed the 4-way method and the last ACK from the server gets dropped, the subsequent FINs from the client do not get ACKed because tcp_v6_send_response does not set the transport header pointer. This causes ah6_output to try to allocate a lot of memory, which typically fails, so the ACKs never make it out of the stack. I have reproduced the problem on kernel 2.6.7, but after looking at the latest kernel it seems the problem is still there. Signed-off-by: Cosmin Ratiu <cratiu@ixiacom.com> Signed-off-by: David S.

when we can send packets again. This patch removes the call to dev_kfree_skb() when the atm device is busy.

2009-09-02tcp: replace hard coded GFP_KERNEL with sk_allocationWu Fengguang
This fixed a lockdep warning which appeared when doing stress memory tests over NFS: inconsistent {RECLAIM_FS-ON-W} -> {IN-RECLAIM_FS-W} usage. page reclaim => nfs_writepage => tcp_sendmsg => lock sk_lock mount_root => nfs_root_data => tcp_close => lock sk_lock => tcp_send_fin => alloc_skb_fclone => page reclaim David raised a concern that if the allocation fails in tcp_send_fin(), and it's GFP_ATOMIC, we are going to yield() (which sleeps) and loop endlessly waiting for the allocation to succeed. But fact is, the original GFP_KERNEL also sleeps. GFP_ATOMIC+yield() looks weird, but it is no worse the implicit sleep inside GFP_KERNEL. Both could loop endlessly under memory pressure.

2009-09-02net/ethtool: Add support for the ethtool feature to flash firmware image ↵Ajit Khaparde
from a specified file. This patch adds support to flash a firmware image to a device using ethtool. The driver gets the filename of the firmware image and flashes the image using the request firmware path. The region "on the chip" to be flashed can be specified by an option. It is upto the device driver to enumerate the region number passed by ethtool, to the region to be flashed. The default behavior is to flash all the regions on the chip.

2009-09-02ip: Report qdisc packet dropsEric Dumazet
Christoph Lameter pointed out that packet drops at qdisc level where not accounted in SNMP counters. Only if application sets IP_RECVERR, drops are reported to user (-ENOBUFS errors) and SNMP counters updated. IP_RECVERR is used to enable extended reliable error message passing, but these are not needed to update system wide SNMP stats. This patch changes things a bit to allow SNMP counters to be updated, regardless of IP_RECVERR being set or not on the socket. Example after an UDP tx flood # netstat -s ... IP: 1487048 outgoing packets dropped ... Udp: ... SndbufErrors: 1487048 send() syscalls, do however still return an OK status, to not break applications. Note : send() manual page explicitly says for -ENOBUFS error : "The output queue for a network interface was full. This generally indicates that the interface has stopped sending, but may be caused by transient congestion. (Normally, this does not occur in Linux. Packets are just silently dropped when a device queue overflows.) " This is not true for IP_RECVERR enabled sockets : a send() syscall that hit a qdisc drop returns an ENOBUFS error.

2009-09-02net: drop_monitor: make last_rx timestamp privateNeil Horman
It was recently pointed out to me that the last_rx field of the net_device structure wasn't updated regularly. In fact only the bonding driver really uses it currently. Since the drop_monitor code relies on the last_rx field to detect drops on recevie in hardware, We need to find a more reliable way to rate limit our drop checks (so that we don't check for drops on every frame recevied, which would be inefficient.

2009-09-02cfg80211: fix looping soft lockup in find_ie()Bob Copeland
The find_ie() function uses a size_t for the len parameter, and directly uses len as a loop variable. If any received packets are malformed, it is possible for the decrease of len to overflow, and since the result is unsigned, the loop will not terminate. Change it to a signed int so the loop conditional works for negative values. This fixes the following soft lockup: [38573.102007] BUG: soft lockup - CPU#0 stuck for 61s!

2009-09-01Revert Backoff [v3]: Calculate TCP's connection close threshold as a time value.Damian Lukowski
RFC 1122 specifies two threshold values R1 and R2 for connection timeouts, which may represent a number of allowed retransmissions or a timeout value. Currently linux uses sysctl_tcp_retries{1,2} to specify the thresholds in number of allowed retransmissions. For any desired threshold R2 (by means of time) one can specify tcp_retries2 (by means of number of retransmissions) such that TCP will not time out earlier than R2. This is the case, because the RTO schedule follows a fixed pattern, namely exponential backoff. However, the RTO behaviour is not predictable any more if RTO backoffs can be reverted, as it is the case in the draft "Make TCP more Robust to Long Connectivity Disruptions" (http://tools.ietf.org/html/draft-zimmermann-tcp-lcd). In the worst case TCP would time out a connection after 3.2 seconds, if the initial RTO equaled MIN_RTO and each backoff has been reverted. This patch introduces a function retransmits_timed_out(N), which calculates the timeout of a TCP connection, assuming an initial RTO of MIN_RTO and N unsuccessful, exponentially backed-off retransmissions. Whenever timeout decisions are made by comparing the retransmission counter to some value N, this function can be used, instead. The meaning of tcp_retries2 will be changed, as many more RTO retransmissions can occur than the value indicates. However, it yields a timeout which is similar to the one of an unpatched, exponentially backing off TCP in the same scenario. As no application could rely on an RTO greater than MIN_RTO, there should be no risk of a regression.

2009-09-01Revert Backoff [v3]: Revert RTO on ICMP destination unreachableDamian Lukowski
Here, an ICMP host/network unreachable message, whose payload fits to TCP's SND.UNA, is taken as an indication that the RTO retransmission has not been lost due to congestion, but because of a route failure somewhere along the path. With true congestion, a router won't trigger such a message and the patched TCP will operate as standard TCP. This patch reverts one RTO backoff, if an ICMP host/network unreachable message, whose payload fits to TCP's SND.UNA, arrives. Based on the new RTO, the retransmission timer is reset to reflect the remaining time, or - if the revert clocked out the timer - a retransmission is sent out immediately. Backoffs are only reverted, if TCP is in RTO loss recovery, i.e. if there have been retransmissions and reversible backoffs, already. Changes from v2: 1) Renaming of skb in tcp_v4_err() moved to another patch. 2) Reintroduced tcp_bound_rto() and __tcp_set_rto(). 3) Fixed code comments.

Mostly just simple conversions: * ray_cs had bogus return of NET_TX_LOCKED but driver was not using NETIF_F_LLTX * hostap and ipw2x00 had some code that returned value from a called function that also had to change to return netdev_tx_t Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

2009-08-31IPVS: Add handling of incoming ICMPV6 messagesJulius Volz
Add handling of incoming ICMPv6 messages. This follows the handling of IPv4 ICMP messages. Amongst ther things this problem allows IPVS to behave sensibly when an ICMPV6_PKT_TOOBIG message is received: This message is received when a realserver sends a packet >PMTU to the client. The hop on this path with insufficient MTU will generate an ICMPv6 Packet Too Big message back to the VIP. The LVS server receives this message, but the call to the function handling this has been missing. Thus, IPVS fails to forward the message to the real server, which then does not adjust the path MTU. This patch adds the missing call to ip_vs_in_icmp_v6() in ip_vs_in() to handle this situation. Thanks to Rob Gallagher from HEAnet for reporting this issue and for testing this patch in production (with direct routing mode).

2009-08-31ipvs: Use atomic operations atomiclySimon Horman
A pointed out by Shin Hong, IPVS doesn't always use atomic operations in an atomic manner. While this seems unlikely to be manifest in strange behaviour, it seems appropriate to clean this up.

2009-08-30pkt_sched: Fix resource limiting in pfifo_fastKrishna Kumar
pfifo_fast_enqueue has this check: if (skb_queue_len(list) < qdisc_dev(qdisc)->tx_queue_len) { which allows each band to enqueue upto tx_queue_len skbs for a total of 3*tx_queue_len skbs. I am not sure if this was the intention of limiting in qdisc. Patch compiled and 32 simultaneous netperf testing ran fine. Also: # tc -s qdisc show dev eth2 qdisc pfifo_fast 0: root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 Sent 16835026752 bytes 373116 pkt (dropped 0, overlimits 0 requeues 25) rate 0bit 0pps backlog 0b 0p requeues 25 Signed-off-by: Krishna Kumar <krkumar2@in.ibm.com> Signed-off-by: David S.
