2007-08-21[SNAP]: Check packet length before readingHerbert Xu
The snap_rcv code reads 5 bytes so we should make sure that we have 5 bytes in the head before proceeding. Based on diagnosis and fix by Evgeniy Polyakov, reported by Alan J. Wylie. Patch also kills the skb->sk assignment before kfree_skb since it's redundant. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

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 Xu
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.

If we hit the 'default:' case of the 'switch' statement, then we return without freeing 'opt', thus leaking 'struct dccp_opt_pend' bytes.

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 Hemminger
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.

2007-08-07[NETFILTER]: ipt_recent: avoid a possible NULL pointer deref in ↵Jesper Juhl
recent_seq_open() If the call to seq_open() returns != 0 then the code calls kfree(st) but then on the very next line proceeds to dereference the pointer - not good. Problem spotted by the Coverity checker. Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-08-07[NetLabel]: add missing rcu_dereference() calls in the LSM domain mapping ↵Paul Moore
hash table The LSM domain mapping head table pointer was not being referenced via the RCU safe dereferencing function, rcu_dereference(). This patch adds those missing calls to the NetLabel code. This has been tested using recent linux-2.6 git kernels with no visible regressions. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-08-07SUNRPC: Fix a race in rpciod_down()Trond Myklebust
The commit 4ada539ed77c7a2bbcb75cafbbd7bd8d2b9bef7b lead to the unpleasant possibility of an asynchronous rpc_task being required to call rpciod_down() when it is complete. This again means that the rpciod workqueue may get to call destroy_workqueue on itself -> hang... Change rpciod_up/rpciod_down to just get/put the module, and then create/destroy the workqueues on module load/unload. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2007-08-02[TCP]: Also handle snd_una changes in tcp_cwnd_downIlpo Järvinen
tcp_cwnd_down must check for it too as it should be conservative in case of collapse stuff and also when receiver is trying to lie (though that wouldn't be very successful/useful anyway). Note: - Separated also is_dupack and do_lost in fast_retransalert * Much cleaner look-and-feel now * This time it really fixes cumulative ACK with many new SACK blocks recovery entry (I claimed this fixes with last patch but it wasn't). TCP will now call tcp_update_scoreboard regardless of is_dupack when in recovery as long as there is enough fackets_out. - Introduce FLAG_SND_UNA_ADVANCED * Some prior_snd_una arguments are unnecessary after it - Added helper FLAG_ANY_PROGRESS to avoid long FLAG...|FLAG... constructs Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S.
