* [INET]: Fix netdev renaming and inet address labelsMark McLoughlin2008-01-04
| | | | | | | | | | | | | | | | | | | | | | | When re-naming an interface, the previous secondary address labels get lost e.g. $> brctl addbr foo $> ip addr add 192.168.0.1 dev foo $> ip addr add 192.168.0.2 dev foo label foo:00 $> ip addr show dev foo | grep inet inet 192.168.0.1/32 scope global foo inet 192.168.0.2/32 scope global foo:00 $> ip link set foo name bar $> ip addr show dev bar | grep inet inet 192.168.0.1/32 scope global bar inet 192.168.0.2/32 scope global bar:2 Turns out to be a simple thinko in inetdev_changename() - clearly we want to look at the address label, rather than the device name, for a suffix to retain.

* [X25]: Add missing x25_neigh_putJulia Lawall2008-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function x25_get_neigh increments a reference count. At the point of the second goto out, the result of calling x25_get_neigh is only stored in a local variable, and thus no one outside the function will be able to decrease the reference count. Thus, x25_neigh_put should be called before the return in this case. The problem was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T,T1,T2; identifier E; statement S; expression x1,x2,x3; int ret; @@ T E; ... * if ((E = x25_get_neigh(...)) == NULL) S ... when != x25_neigh_put(...,(T1)E,...) when != if (E != NULL) { ... x25_neigh_put(...,(T1)E,...); ...} when != x1 = (T1)E when != E = x3; when any if (...) { ... when != x25_neigh_put(...,(T2)E,...) when != if (E != NULL) { ... x25_neigh_put(...,(T2)E,...); ...} when != x2 = (T2)E ( * return; | * return ret; ) } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

* [TCP]: use non-delayed ACK for congestion control RTTGavin McCullagh2007-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a delayed ACK representing two packets arrives, there are two RTT samples available, one for each packet. The first (in order of seq number) will be artificially long due to the delay waiting for the second packet, the second will trigger the ACK and so will not itself be delayed. According to rfc1323, the SRTT used for RTO calculation should use the first rtt, so receivers echo the timestamp from the first packet in the delayed ack. For congestion control however, it seems measuring delayed ack delay is not desirable as it varies independently of congestion. The patch below causes seq_rtt and last_ackt to be updated with any available later packet rtts which should have less (and hopefully zero) delack delay. The rtt value then gets passed to ca_ops->pkts_acked(). Where TCP_CONG_RTT_STAMP was set, effort was made to supress RTTs from within a TSO chunk (!fully_acked), using only the final ACK (which includes any TSO delay) to generate RTTs. This patch removes these checks so RTTs are passed for each ACK to ca_ops->pkts_acked(). For non-delay based congestion control (cubic, h-tcp), rtt is sometimes used for rtt-scaling. In shortening the RTT, this may make them a little less aggressive. Delay-based schemes (eg vegas, veno, illinois) should get a cleaner, more accurate congestion signal, particularly for small cwnds. The congestion control module can potentially also filter out bad RTTs due to the delayed ack alarm by looking at the associated cnt which (where delayed acking is in use) should probably be 1 if the alarm went off or greater if the ACK was triggered by a packet.

* [IPV4] Fix ip=dhcp regressionSimon Horman2007-12-28
| | | | | | | | | | | | | | | | | | | David Brownell pointed out a regression in my recent "Fix ip command line processing" patch. It turns out to be a fairly blatant oversight on my part whereby ic_enable is never set, and thus autoconfiguration is never enabled. Clearly my testing was broken :-( The solution that I have is to set ic_enable to 1 if we hit ip_auto_config_setup(), which basically means that autoconfiguration is activated unless told otherwise. I then flip ic_enable to 0 if ip=off, ip=none, ip=::::::off or ip=::::::none using ic_proto_name(); The incremental patch is below, let me know if a non-incremental version is prepared, as I did as for the original patch to be reverted pending a fix.

* [IPV4]: Fix ip command line processing.Simon Horman2007-12-26
| | | | | | | | | | | | | | | | Recently the documentation in Documentation/nfsroot.txt was update to note that in fact ip=off and ip=::::::off as the latter is ignored and the default (on) is used. This was certainly a step in the direction of reducing confusion. But it seems to me that the code ought to be fixed up so that ip=::::::off actually turns off ip autoconfiguration. This patch also notes more specifically that ip=on (aka ip=::::::on) is the default. Signed-off-by: Simon Horman <horms@verge.net.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETFILTER]: nf_conntrack_ipv4: fix module parameter compatibilityPatrick McHardy2007-12-26
| | | | | | | | | | | | | | | | | Some users do "modprobe ip_conntrack hashsize=...". Since we have the module aliases this loads nf_conntrack_ipv4 and nf_conntrack, the hashsize parameter is unknown for nf_conntrack_ipv4 however and makes it fail. Allow to specify hashsize= for both nf_conntrack and nf_conntrack_ipv4. Note: the nf_conntrack message in the ringbuffer will display an incorrect hashsize since nf_conntrack is first pulled in as a dependency and calculates the size itself, then it gets changed through a call to nf_conntrack_set_hashsize().

* [NET]: Fix function put_cmsg() which may cause usr application memory overflowWei Yongjun2007-12-20

| | | | | | | | | | | | | | | | | The aalgos/ealgos fields are only 32 bits wide. However, af_key tries to test them with the expression 1 << id where id can be as large as 253. This produces different behaviour on different architectures. The following patch explicitly checks whether ID is greater than 31 and fails the check if that's the case. We cannot easily extend the mask to be longer than 32 bits due to exposure to user-space. Besides, this whole interface is obsolete anyway in favour of the xfrm_user interface which doesn't use this bit mask in templates (well not within the kernel anyway).

| | | | | | | | | | | | | | | | | | | | | | | | | | | As noted by Kevin, tipc's release() does down_interruptible() and ignores the return value. So if signal_pending() we'll end up doing up() on a non-downed semaphore. Fix. Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* | | [XFRM]: Display the audited SPI value in host byte order.Paul Moore2007-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the IPsec protocol SPI values are written to the audit log in network byte order which is different from almost all other values which are recorded in host byte order. This patch corrects this inconsistency by writing the SPI values to the audit record in host byte order. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S.

* | | [NETFILTER]: ip_tables: fix compat copy racePatrick McHardy2007-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When copying entries to user, the kernel makes two passes through the data, first copying all the entries, then fixing up names and counters. On the second pass it copies the kernel and match data from userspace to the kernel again to find the corresponding structures, expecting that kernel pointers contained in the data are still valid. This is obviously broken, fix by avoiding the second pass completely and fixing names and counters while dumping the ruleset, using the kernel-internal data structures.

* | [IPSEC]: Fix potential dst leak in xfrm_lookupHerbert Xu2007-12-11
| | | | | | | | | | | | | | | | | | | | | | If we get an error during the actual policy lookup we don't free the original dst while the caller expects us to always free the original dst in case of error. This patch fixes that. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* | [VLAN]: Fix potential race in vlan_cleanup_module vs vlan_ioctl_handler.Pavel Emelyanov2007-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vlan module cleanup function starts with vlan_netlink_fini(); vlan_ioctl_set(NULL); The first call removes all the vlan devices and the second one closes the vlan ioctl. AFAIS there's a tiny race window between these two calls - after rtnl unregistered all the vlans, but the ioctl handler isn't set to NULL yet, user can manage to call this ioctl and create one vlan device, and that this function will later BUG_ON seeing non-emply hashes. I think, that we must first close the vlan ioctl and only after this remove all the vlans with the vlan_netlink_fini() call.
