v2 cover SLIRP VMStatification [ for 2.9 ]

From: "Dr. David Alan Gilbert" <[email protected]>

Hi,
This is an update to my previous series that included VMSTATE_WITH_TMP.
I've not bothered including the VMSTATE_WITH_TMP set this time; but it's still dependent on it, so we'll wait until it's in first.

My main change in this version is that I've commoned the fhost/lhost unions
in struct socket, and that's made the 'socket level' code a lot simpler and should make it a lot easier to add IPv6 support to it.

Dave

Dr. David Alan Gilbert (10):
slirp: VMState conversion; tcpcb
slirp: VMStatify sbuf
slirp: Common lhost/fhost union
slirp: VMStatify socket level
slirp: VMStatify remaining except for loop

PATCH v2 1/5 slirp: VMState conversion; tcpcb

From: "Dr. David Alan Gilbert" <[email protected]>

Convert the migration of the struct tcpcb to use a VMStateDescription, the rest of it will come later.

Mostly mechanical, except for conversion of some 'char' to uint8_t to ensure portability.

PATCH v2 2/5 slirp: VMStatify sbuf

In reply to Dr. David Alan Gilbert (git)

From: "Dr. David Alan Gilbert" <[email protected]>

Convert the sbuf structure to a VMStateDescription. Note this uses the VMSTATE_WITH_TMP mechanism to calculate and reload the offsets based on the pointers.

PATCH v2 3/5 slirp: Common lhost/fhost union

In reply to Dr. David Alan Gilbert (git)

From: "Dr. David Alan Gilbert" <[email protected]>

The socket structure has a pair of unions for lhost and fhost addresses; the unions are identical so split them out into a separate union declaration.

Working up the stack, this replaces the slirp_socket_load/save with VMState definitions.

Reading again your previous post, it seemed it'd be in slirp_family_inet, but I don't immediately see how.

Applying your patch for 2.9 would thus make porting the code to IPv6 more difficult than how it is now, so I'm quite reluctant :)

Could you perhaps simply add the IPv6 case in your patch series already? It shouldn't be much work for you who actually know how the VMSTATE machinery is supposed to work (I guess the amount of people who care about slirp *and* know about VMSTATE is extremely small), and a proof of concept for the portability to non-ipv4 addresse spaces.

The number of people who care about slirp, IPv6, VMState is even smaller :-) Hmm, I don't really know IPv6 but I'm thinking this code will become something like the following (says he not knowing whether a scope-id or a flowinfo
is something that needs migrating) (untested):

static const VMStateDescription vmstate_slirp_socket_addr = {
.name = "slirp-socket-addr",
.version_id = 4,
.fields = (VMStateField[]) {
VMSTATE_UINT16(ss.ss_family, union slirp_sockaddr), VMSTATE_UINT32_TEST(sin.sin_addr.s_addr, union slirp_sockaddr,
slirp_family_inet),
VMSTATE_UINT16_TEST(sin.sin_port, union slirp_sockaddr,
slirp_family_inet),

VMSTATE_BUFFER_TEST(sin6.sin6_addr, union slirp_sockaddr,
slirp_family_inet6),
VMSTATE_UINT16_TEST(sin6.sin6_port, union slirp_sockaddr,
slirp_family_inet6),
VMSTATE_UINT32_TEST(sin6.sin6_flowinfo, union slirp_sockaddr,
slirp_family_inet6),
VMSTATE_UINT32_TEST(sin6.sin6_scope_id, union slirp_sockaddr,
slirp_family_inet6),

VMSTATE_END_OF_LIST()
}
};

So to me that looks pretty clean, we need to add another slirp_family_inet6 test function, but then we just add the extra fields for the IPv6 stuff.

Can you suggest an IPv6 command line for testing that ?

Well, it doesn't exist yet, that's the problem. And applying your patch would have made it to exist even harder, so that's why I was afraid.

I would say that your patch should contain these IPv6 lines, but as comments since they are untested, for the person who will at some point want to implement the IPv6 case here.
