A similar fix to netfilter from Eric Dumazet inspired me to
look around a bit by using some grep/sed stuff as looking for
this kind of bugs seemed easy to automate. This is one of them
I found where it looks like this semicolon is not valid.

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(); }

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.

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.

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.

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.

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...

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

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...

Although an ipsec SA was established, kernel couldn't seem to find it.
I think since we are now using "x->sel.family" instead of "family" in
the xfrm_selector_match() called in xfrm_state_find(), af_key needs to
set this field too, just as xfrm_user.
In af_key.c, x->sel.family only gets set when there's an
ext_hdrs[SADB_EXT_ADDRESS_PROXY-1] which I think is for tunnel.
I think pfkey needs to also set the x->sel.family field when it is 0.
Tested with below patch, and ipsec worked when using pfkey.
