This always bugged me: dev_ioctl() called dev_ifsioc() either inside
read_lock(dev_base_lock) or rtnl_lock(), depending on the ioctl being
executed.
This change moves the ioctls executed inside dev_base_lock to a new
function, dev_ifsioc_locked(). Now the locking context is completely
clear to the reader.

Fix a bunch of sparse warnings. Mostly about 0 used as
NULL pointer, and shadowed variable declarations.
One notable case was that hash size should have been unsigned.

1) Passing wrong skb to tcp_adjust_fackets_out could corrupt
fastpath_cnt_hint as tcp_skb_pcount(next_skb) is not included
to it if hint points exactly to the next_skb (it's lagging
behind, see sacktag).
2) When fastpath_skb_hint is put backwards to avoid dangling
skb reference, the skb's pcount must also be removed from count
(not included like above).

This fixes two bugs in processing of connection-Requests in
v{4,6}_conn_request:
1. Due to using the variable `reset_code', the Reset code generated
internally by dccp_parse_options() is overwritten with the
initialised value ("Too Busy") of reset_code, which is not what is
intended.
2. When receiving a connection-Request on a multicast or broadcast
address, no Reset should be generated, to avoid storms of such
packets. Instead of jumping to the `drop' label, the
v{4,6}_conn_request functions now return 0. Below is why in my
understanding this is correct:
When the conn_request function returns < 0, then the caller,
dccp_rcv_state_process(), returns 1. In all instances where
dccp_rcv_state_process is called (dccp_v4_do_rcv, dccp_v6_do_rcv,
and dccp_child_process), a return value of != 0 from
dccp_rcv_state_process() means that a Reset is generated.
If on the other hand the conn_request function returns 0, the
packet is discarded and no Reset is generated.
Note: There may be a related problem when sending the Response, due to
the following.
if (dccp_v6_send_response(sk, req, NULL))
goto drop_and_free;
/* ... */
drop_and_free:
return -1;
In this case, if send_response fails due to transmission errors, the
next thing that is generated is a Reset with a code "Too Busy". I
haven't been able to conjure up such a condition, but it might be good
to change the behaviour here also (not done by this patch).

This
* removes a declaration of a non-existent function
__dccp_minisock_init;
* shifts the initialisation function dccp_minisock_init() from
options.c to minisocks.c, where it is more naturally expected to
be.

This replaces several uses of standard arithmetic with the DCCP
sequence number arithmetic functions. The problem here is that the
sequence number wrap-around was not taken into consideration.
* Condition "seqp->ccid2s_seq <= prev->ccid2s_seq" has been replaced
by
dccp_delta_seqno(seqp->ccid2s_seq, prev->ccid2s_seq) >= 0
since if seqp is `before' prev, then the delta_seqno() is positive.
* The test whether sequence numbers `a' and `b' are consecutive has
the form
dccp_delta_seqno(a, b) == 1
* Increment of ccid2hctx_rpseq could be done using dccp_inc_seqno(),
but since here the incremented ccid2hctx_rpseq == seqno, used
assignment instead.

skb's passed to ccid2_hc_tx_send_packet() are headerless, the packet

This removes an ugly BUG_ON which has been pointed out by Arnaldo.
Instead of freezing up the machine, a `critical' message is now issued
to the system log.
There is potential of doing this more gracefully (eg. there are a few
internal variables which could be updated despite the lack of memory),
but that requires more complicated changes to the algorithm; thus a
`FIXME' has been added.

This patch simplifies the interface of ccid2_hc_tx_alloc_seq():
* ccid2_hc_tx_alloc_seq() is always called with an argument of
CCID2_SEQBUF_LEN;
* other code - ccid2_hc_tx_check_sanity() - even depends on the
assumption that ccid2_hc_tx_alloc_seq() has been called with this
particular size;
* passing the `gfp_t' argument to ccid2_hc_tx_alloc_seq() is
redundant with gfp_any().

This enables applications to query the current value of the Maximum
Packet Size via a socket option, suggested as a SHOULD in (RFC 4340,
p. 102).
This socket option is useful to avoid the annoying bail-out via
`-EMSGSIZE'. In particular, as fragmentation is not currently
supported (and its use is partly discouraged in RFC 4340).
With this option, it is possible to size buffers accordingly, e.g.
int buflen = dccp_get_cur_mps(sockfd);
/* or */
if (msgsize > dccp_get_cur_mps(sockfd))
die("message is too large for this path");

This performs a minor optimisation: when ccid_hc_tx_send_packet
returns a value greater zero, then the same call previously was done
again at the begin of the while loop in dccp_wait_for_ccid.
This patch exploits the available information and schedule-timeouts
directly instead.

This patch adds sta_notify callback and removes sta_table_notification
which was not used by any driver.
sta_notify() is essential for drivers that keeps notion of station
internally and need to be notified about removal or addition of a station
to the (I)BSS or assocation to an AP.

This improves radiotap injection by removing the shortcut over TX handlers
that led to BUGS when injecting frames without setting a rate and also
resulted in various other quirks. Now, TX handlers are run but some
information that was present in the radiotap header is used instead of
automatic settings.

Just came across what RFC2018 states about generation of valid
SACK blocks in case of reneging. Alter comment a bit to point

IMHO, there isn't any reason to change code because the
validation is there for a purpose (counters will inform user
about decision TCP made if this case ever surfaces).
