2007-08-30SCTP: Use net_ratelimit to suppress error messages print too fastWei Yongjun2-14/+17
When multi bundling SHUTDOWN-ACK message is received in ESTAB state, this will cause "sctp protocol violation state" message print many times. If SHUTDOWN-ACK is bundled 300 times in one packet, message will be print 300 times. The same problem also exists when received unexpected HEARTBEAT-ACK message which is bundled message times. This patch used net_ratelimit() to suppress error messages print too fast. Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
2007-08-30SCTP: Fix to encode PROTOCOL VIOLATION error cause correctlyWei Yongjun2-23/+54
PROTOCOL VIOLATION error cause in ABORT is bad encode when make abort chunk. When SCTP encode ABORT chunk with PROTOCOL VIOLATION error cause, it just add the error messages to PROTOCOL VIOLATION error cause, the rest four bytes(struct sctp_paramhdr) is just add to the chunk, not change the length of error cause. This cause the ABORT chunk to be a bad format. The chunk is like this: ABORT chunk Chunk type: ABORT (6) Chunk flags: 0x00 Chunk length: 72 (*1) Protocol violation cause Cause code: Protocol violation (0x000d) Cause length: 62 (*2) Cause information: 5468652063756D756C61746976652074736E2061636B2062... Cause padding: 0000 [Needless] 00030010 Chunk Length(*1) = 72 but Cause length(*2) only 62, not include the extend 4 bytes. ((72 - sizeof(chunk_hdr)) = 68) != (62 +3) / 4 * 4 Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>

2007-08-29SCTP: Assign stream sequence numbers to the entire messageVlad Yasevich1-12/+23
Currently we only assign the sequence number to a packet that we are about to transmit. This however breaks the Partial Reliability extensions, because it's possible for us to never transmit a packet, i.e. it expires before we get to send it. In such cases, if the message contained multiple SCTP fragments, and we did manage to send the first part of the message, the Stream sequence numbers would get into invalid state and cause receiver to stall.

2007-08-29SCTP: properly clean up fragment and ordering queues during FWD-TSN.Vlad Yasevich2-13/+65
When we recieve a FWD-TSN (meaning the peer has abandoned the data), we need to clean up any partially received messages that may be hanging out on the re-assembly or re-ordering queues.

2007-08-26[VLAN/BRIDGE]: Fix "skb_pull_rcsum - Fatal exception in interrupt"Evgeniy Polyakov2-6/+18
I tried to preserve bridging code as it was before, but logic is quite strange - I think we should free skb on error, since it is already unshared and thus will just leak. Herbert Xu states: > + if ((skb = skb_share_check(skb, GFP_ATOMIC)) == NULL) > + goto out; If this happens it'll be a double-free on skb since we'll return NF_DROP which makes the caller free it too. We could return NF_STOLEN to prevent that but I'm not sure whether that's correct netfilter semantics. Patrick, could you please make a call on this? Patrick McHardy states: NF_STOLEN should work fine here. Signed-off-by: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-08-26[IPSEC] AH4: Update IPv4 options handling to conform to RFC 4302.Nick Bowler1-1/+1
In testing our ESP/AH offload hardware, I discovered an issue with how AH handles mutable fields in IPv4. RFC 4302 (AH) states the following on the subject: For IPv4, the entire option is viewed as a unit; so even though the type and length fields within most options are immutable in transit, if an option is classified as mutable, the entire option is zeroed for ICV computation purposes. The current implementation does not zero the type and length fields, resulting in authentication failures when communicating with hosts that do (i.e. FreeBSD). I have tested record route and timestamp options (ping -R and ping -T) on a small network involving Windows XP, FreeBSD 6.2, and Linux hosts, with one router. In the presence of these options, the FreeBSD and Linux hosts (with the patch or with the hardware) can communicate. The Windows XP host simply fails to accept these packets with or without the patch. I have also been trying to test source routing options (using traceroute -g), but haven't had much luck getting this option to work *without* AH, let alone with.

2007-08-13[IPVS]: Use IP_VS_WAIT_WHILE when encessary.Heiko Carstens1-1/+1
For architectures that don't have a volatile atomic_ts constructs like while (atomic_read(&something)); might result in endless loops since a barrier() is missing which forces the compiler to generate code that actually reads memory contents. Fix this in ipvs by using the IP_VS_WAIT_WHILE macro which resolves to while (expr) { cpu_relax(); } (why isn't this open coded btw?)

2007-08-13[NET]: Share correct feature code between bridging and bondingHerbert Xu3-33/+44
http://bugzilla.kernel.org/show_bug.cgi?id=8797 shows that the bonding driver may produce bogus combinations of the checksum flags and SG/TSO. For example, if you bond devices with NETIF_F_HW_CSUM and NETIF_F_IP_CSUM you'll end up with a bonding device that has neither flag set. If both have TSO then this produces an illegal combination. The bridge device on the other hand has the correct code to deal with this. In fact, the same code can be used for both. So this patch moves that logic into net/core/dev.c and uses it for both bonding and bridging. In the process I've made small adjustments such as only setting GSO_ROBUST if at least one constituent device supports it.

2007-08-13[DCCP]: fix memory leak and clean up style - dccp_feat_empty_confirm()Jesper Juhl1-4/+10
There's a memory leak in net/dccp/feat.c::dccp_feat_empty_confirm(). If we hit the 'default:' case of the 'switch' statement, then we return without freeing 'opt', thus leaking 'struct dccp_opt_pend' bytes. The leak is fixed easily enough by adding a kfree(opt); before the return statement. The patch also changes the layout of the 'switch' to be more in line with CodingStyle.

2007-08-13[IPCONFIG]: ip_auto_config fixJoakim Tjernlund1-3/+3
The following commandline: root=/dev/mtdblock6 rw rootfstype=jffs2 ip=192.168.1.10:::255.255.255.0:localhost.localdomain:eth1:off console=ttyS0,115200 makes ip_auto_config fall back to DHCP and complain "IP-Config: Incomplete network configuration information." depending on if CONFIG_IP_PNP_DHCP is set or not. The only way I can make ip_auto_config accept my IP config is to add an entry for the server IP: ip=192.168.1.10:192.168.1.15::255.255.255.0:localhost.localdomain:eth1:off I think this is a bug since I am not using a NFS root FS. The following patch fixes the above problem. From: Andrew Morton <akpm@linux-foundation.org> Davem said (in February!): Well, first of all the change in question is not in 2.4.x either. I just checked the current 2.4.x GIT tree and the test is exactly: if (ic_myaddr == INADDR_NONE || #ifdef CONFIG_ROOT_NFS (MAJOR(ROOT_DEV) == UNNAMED_MAJOR && root_server_addr == INADDR_NONE && ic_servaddr == INADDR_NONE) || #endif ic_first_dev->next) { which matches 2.6.x I even checked 2.4.x when it was branched for 2.5.x and the test was the same at the point in time too. Looking at the proposed change a bit it appears that it is probably correct, as it's trying to check that ROOT_DEV is nfs root. But if it is correct then the UNNAMED_MAJOR comparison in the same code block should be removed as it becomes superfluous. I'm happy to apply this patch with that modification made.

2007-08-07[TCP]: H-TCP maxRTT estimation at startupStephen Hemminger1-3/+1
Small patch to H-TCP from Douglas Leith. Fix estimation of maxRTT. The original code ignores rtt measurements during slow start (via the check tp->snd_ssthresh < 0xFFFF) yet this is probably a good time to try to estimate max rtt as delayed acking is disabled and slow start will only exit on a loss which presumably corresponds to a maxrtt measurement. Second, the original code (via the check htcp_ccount(ca) > 3) ignores rtt data during what it estimates to be the first 3 round-trip times. This seems like an unnecessary check now that the RCV timestamp are no longer used for rtt estimation. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S.
