The bridge currently floods packets to groups that we have never
seen before to all ports. This is not required by RFC4541 and
in fact it is not desirable in environment where traffic to
unregistered group is always present.
This patch changes the behaviour so that we only send traffic
to unregistered groups to ports marked as routers.
The user can always force flooding behaviour to any given port
by marking it as a router.
Note that this change does not apply to traffic to 224.0.0.X
as traffic to those groups must always be flooded to all ports.

I cannot speak on behalf of the batman-adv developers due to conflicts

still maintained by Marek Lindner and Simon Wunderlich. Those are the
main persons behind the visions of batman-adv. Therefore, the state of

In commit 3ac5e26a1e entitled
"rtlwifi: rtl8192c-common: Change common firmware routines for addition
of rtl8192se and rtl8192de", the firmware loading code was moved.
Unfortunately, some necessary code was dropped for rtl8192cu.
The dmesg output shows the following:
rtl8192c: Loading firmware file rtlwifi/rtl8192cufw.bin
rtl8192c_common:_rtl92c_fw_free_to_go():<0-0> Polling FW ready fail!! REG_MCUFWDL:0x00000006 .
rtl8192c_common:rtl92c_download_fw():<0-0> Firmware is not ready to run!
In addition, the interface will authenticate and associate, but cannot
transfer data.
This is reported as Kernel Bug #38012.

Consider this scenario: When the size of the first received udp packet
is bigger than the receive buffer, MSG_TRUNC bit is set in msg->msg_flags.
However, if checksum error happens and this is a blocking socket, it will
goto try_again loop to receive the next packet. But if the size of the
next udp packet is smaller than receive buffer, MSG_TRUNC flag should not
be set, but because MSG_TRUNC bit is not cleared in msg->msg_flags before
receive the next packet, MSG_TRUNC is still set, which is wrong.
Fix this problem by clearing MSG_TRUNC flag when starting over for a
new packet.

udpv6_recvmsg() function is not using the correct variable to determine
whether or not the socket is in non-blocking operation, this will lead
to unexpected behavior when a UDP checksum error occurs.
Consider a non-blocking udp receive scenario: when udpv6_recvmsg() is
called by sock_common_recvmsg(), MSG_DONTWAIT bit of flags variable in
udpv6_recvmsg() is cleared by "flags & ~MSG_DONTWAIT" in this call:
err = sk->sk_prot->recvmsg(iocb, sk, msg, size, flags & MSG_DONTWAIT,
flags & ~MSG_DONTWAIT, &addr_len);
i.e. with udpv6_recvmsg() getting these values:
int noblock = flags & MSG_DONTWAIT
int flags = flags & ~MSG_DONTWAIT
So, when udp checksum error occurs, the execution will go to
csum_copy_err, and then the problem happens:
csum_copy_err:
...............
if (flags & MSG_DONTWAIT)
return -EAGAIN;
goto try_again;
...............
But it will always go to try_again as MSG_DONTWAIT has been cleared
from flags at call time -- only noblock contains the original value
of MSG_DONTWAIT, so the test should be:
if (noblock)
return -EAGAIN;
This is also consistent with what the ipv4/udp code does.

Commit 13e12d14e2 ("vfs: reorganize 'struct inode' layout a bit")
moved things around a bit changed i_state to be unsigned int instead of
unsigned long. That was to help structure layout for the 64-bit case,
and shrink 'struct inode' a bit (admittedly that only happened when
spinlock debugging was on and i_flags didn't pack with i_lock).
However, Meelis Roos reports that this results in unaligned exceptions
on sprc, and it turns out that the bit-locking primitives that we use
for the I_NEW bit want to use the bitops. Which want 'unsigned long',
not 'unsigned int'.
We really should fix the bit locking code to not have that kind of
requirement, but that's a much bigger change. So for now, revert that
field back to 'unsigned long' (but keep the other re-ordering changes
from the commit that caused this).
Andi points out that we have played games with this in 'struct page', so
it's solvable with other hacks too, but since right now the struct inode
size advantage only happens with some rare config options, it's not
worth fighting.
It _would_ be worth fixing the bitlocking code, though. Especially
since there is no type safety in the bitlocking code (this never caused
any warnings, and worked fine on x86-64, because the bitlocks take a
'void *' and x86-64 doesn't care that deeply about alignment). So it's
currently a very easy problem to trigger by mistake and never notice.
