This module and a bunch of dependancies are getting loaded on several
of laptops I have (probably picking up the mobile broadband device),
that have nothing to do with zaurus. Matching by class without
any vendor/device pair isn't the right thing to do here, as it
will prevent any other driver from correctly binding to it.
(Or in the absense of a driver, will just waste time & memory by
unnecessarily loading modules)Signed-off-by: Dave Jones

Avoid creating input routes with ip_route_me_harder.
It does not work for locally generated packets. Instead,
restrict sockets to provide valid saddr for output route (or
unicast saddr for transparent proxy). For other traffic
allow saddr to be unicast or local but if callers forget
to check saddr type use 0 for the output route.The resulting handling should be:
- REJECT TCP:
- in INPUT we can provide addr_type = RTN_LOCAL but
better allow rejecting traffic delivered with
local route (no IP address => use RTN_UNSPEC to
allow also RTN_UNICAST).
- FORWARD: RTN_UNSPEC => allow RTN_LOCAL/RTN_UNICAST
saddr, add fix to ignore RTN_BROADCAST and RTN_MULTICAST
- OUTPUT: RTN_UNSPEC- NAT, mangle, ip_queue, nf_ip_reroute: RTN_UNSPEC in LOCAL_OUT
- IPVS:
- use RTN_LOCAL in LOCAL_OUT and FORWARD after SNAT
to restrict saddr to be localSigned-off-by: Julian Anastasov

ip_append_data() builds packets based on the mtu from dst_mtu(rt->dst.path).
On IPsec the effective mtu is lower because we need to add the protocol
headers and trailers later when we do the IPsec transformations. So after
the IPsec transformations the packet might be too big, which leads to a
slowpath fragmentation then. This patch fixes this by building the packets
based on the lower IPsec mtu from dst_mtu(&rt->dst) and adapts the exthdr
handling to this.Signed-off-by: Steffen Klassert

Git commit 59104f06 (ip: take care of last fragment in ip_append_data)
added a check to see if we exceed the mtu when we add trailer_len.
However, the mtu is already subtracted by the trailer length when the
xfrm transfomation bundles are set up. So IPsec packets with mtu
size get fragmented, or if the DF bit is set the packets will not
be send even though they match the mtu perfectly fine. This patch
actually reverts commit 59104f06.Signed-off-by: Steffen Klassert

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.Signed-off-by: Herbert Xu

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.Signed-off-by: Xufeng Zhang

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_DONTWAITSo, 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 13e12d14e2dc ("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.Reported-by: Meelis Roos
