* [UNIX] Move the unix sock iterators in to proper placePavel Emelyanov2008-01-281-26/+23
| | | | | | | | | | | | | | The first_unix_socket() and next_unix_sockets() are now used in proc file and in forall_unix_socets macro only. The forall_unix_sockets is not used in this file at all so remove it. After this move the helpers to where they really belong, i.e. closer to proc code under the #ifdef CONFIG_PROC_FS option.

* [DCCP]: Remove redundant dependency on IP_DCCPGerrit Renker2008-01-281-3/+1
| | | | | | | | | | | | | | This cleans up the consequences of an earlier patch which introduced the `if IP_DCCP' clause into net/dccp/Kconfig. The CCID Kconfig menu is sourced within this clause; as a consequence, all tests of type `depends on IP_DCCP' are now redundant.

* [DCCP]: Promote CCID2 as default CCIDGerrit Renker2008-01-283-13/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses the following problems: 1. DCCP relies for its proper functioning on having at least one CCID module enabled (as in TCP plugable congestion control). Currently it is possible to disable both CCIDs and thus leave the DCCP module in a compiled, but entirely non-functional state: no sockets can be created when no CCID is available. Furthermore, the protocol is (again like TCP) not intended to be used without CCIDs. Last, a non-empty CCID list is needed for doing CCID feature negotiation. 2. Internally the default CCID that is advertised by the Linux host is set to CCID2 (DCCPF_INITIAL_CCID in include/linux/dccp.h). Disabling CCID2 in the Kconfig menu without changing the defaults leads to a failure `module not found' when trying to load the dccp module (which internally tries to load the default CCID). 3. The specification (RFC 4340, sec. 10) treats CCID2 somewhat like a `minimum common denominator'; the specification says that: * "New connections start with CCID 2 for both endpoints" * "A DCCP implementation intended for general use, such as an implementation in a general-purpose operating system kernel, SHOULD implement at least CCID 2. The intent is to make CCID 2 broadly available for interoperability [...]" Providing CCID2 as minimum-required CCID (like Reno/Cubic in TCP) thus seems reasonable. Hence this patch automatically selects CCID2 when DCCP is enabled. Documentation also added. Discussions with Ian McDonald on this subject are gratefully acknowledged.

* [DCCP]: Honour and make use of shutdown option set by userGerrit Renker2008-01-283-8/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This extends the DCCP socket API by honouring any shutdown(2) option set by the user. The behaviour is, as much as possible, made consistent with the API for TCP's shutdown. This patch exploits the information provided by the user via the socket API to reduce processing costs: * if the read end is closed (SHUT_RD), it is not necessary to deliver to input CCID; * if the write end is closed (SHUT_WR), the same idea applies, but with a difference - as long as the TX queue has not been drained, we need to receive feedback to keep congestion-control rates up to date. Hence SHUT_WR is honoured only after the last packet (under congestion control) has been sent; * although SHUT_RDWR seems nonsensical, it is nevertheless supported in the same manner as for TCP (and agrees with test for SHUTDOWN_MASK in dccp_poll() in net/dccp/proto.c). Furthermore, most of the code already honours the sk_shutdown flags (dccp_recvmsg() for instance sets the read length to 0 if SHUT_RD had been called); CCID handling is now added to this by the present patch. There will also no longer be any delivery when the socket is in the final stages, i.e. when one of dccp_close(), dccp_fin(), or dccp_done() has been called - which is fine since at that stage the connection is its final stages. Motivation and background are on http://www.erg.abdn.ac.uk/users/gerrit/dccp/notes/shutdown A FIXME has been added to notify the other end if SHUT_RD has been set (RFC 4340, 11.7). Note: There is a comment in inet_shutdown() in net/ipv4/af_inet.c which asks to "make sure the socket is a TCP socket". This should probably be extended to mean `TCP or DCCP socket' (the code is also used by UDP and raw sockets).

* [DCCP]: Make PARTOPEN an autonomous stateGerrit Renker2008-01-281-11/+3
| | | | | | | | | | | | | | | | This decouples PARTOPEN from TCP-specific stream-states. It thus addresses the FIXME. The code has been checked with regard to dependency on PARTOPEN and FIN_WAIT1 states (to which PARTOPEN previously was mapped): there is no difference, as PARTOPEN is always referred to directly (i.e. not via the mapping to TCP state).

| | | | | | | | | | | | | This fixes/updates the handling of idle and application-limited periods in CCID3, which currently is broken: there is no detection as to how long a sender has been idle - there is only one flag which is toggled in between function calls.

* [CCID3]: Ignore trivial amounts of elapsed timeGerrit Renker2008-01-282-11/+1
| | | | | | | | | | | | | | | | | | | | | This patch fixes a previously undiscovered bug; the problem is in computing the elapsed time as the time between `receiving' the packet (i.e. skb enters CCID module) and sending feedback: - there is no layer-processing, queueing, or delay involved, - hence the elapsed time is in the order of 1 function call - this is in the dimension of maximally 50..100usec - which renders the use of elapsed time almost entirely useless. The fix is simply to ignore such trivial amounts of elapsed time. As a further advantage, the now useless elapsed_time field can be removed from the socket, which reduces the socket structure by another four bytes.

Indeed the code that cleans up also schedule work in keventd: as long as cleanup_net() hasn't return, dst_gc_task() cannot run and as long as dst_gc_task() has not run, there are still some references pending on the net devices and cleanup_net() can not unregister and exit the keventd workqueue.

* [PATCH] IPV4 : Move ip route cache flush (secret_rebuild) from softirq to ↵Eric Dumazet2008-01-281-24/+59
| | | | | | | | | | | | | | | | | | | | | | workqueue Every 600 seconds (ip_rt_secret_interval), a softirq flush of the whole ip route cache is triggered. On loaded machines, this can starve softirq for many seconds and can eventually crash. This patch moves this flush to a workqueue context, using the worker we intoduced in commit 39c90ece7565f5c47110c2fa77409d7a9478bd5b (IPV4: Convert rt_check_expire() from softirq processing to workqueue.) Also, immediate flushes (echo 0 >/proc/sys/net/ipv4/route/flush) are using rt_do_flush() helper function, wich take attention to rescheduling. Next step will be to handle delayed flushes ("echo -1 >/proc/sys/net/ipv4/route/flush" or "ip route flush cache") Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

* ieee80211: Add IEEE80211_MAX_FRAME_LEN to linux/ieee80211.hMichael Wu2008-01-281-7/+7
| | | | | | | | | | | | | | | This patch adds IEEE80211_MAX_FRAME_LEN which is useful for drivers trying to determine how much to allocate for their RX buffers. It also updates the comment on IEEE80211_MAX_DATA_LEN based on revisions in 802.11e. IEEE80211_MAX_FRAG_THRESHOLD and IEEE80211_MAX_RTS_THRESHOLD are also revised due to the new maximum frame size.

* mac80211: Accept auto txpower settingMattias Nissler2008-01-281-4/+17
| | | | | | | | | | | This changes the SIWTXPOWER ioctl to also accept a txpower setting of "automatic". Since mac80211 currently cannot tell drivers to automatically adjust tx power, we select the tx power level of the current channel. While this is kind of a hack, it certainly saves some iwconfig users from headaches. Signed-off-by: Mattias Nissler <mattias.nissler@gmx.de> Signed-off-by: John W.

* [NETPOLL]: Don't need rx_flags.Stephen Hemminger2008-01-282-8/+3
| | | | | | | | The rx_flags variable is redundant. Turning rx on/off is done via setting the rx_np pointer. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* [TCP]: Correct DSACK check placingIlpo Järvinen2008-01-281-10/+5
| | | | | | | | | | | Previously one of the in-block skip branches was missing it. Also, drop it from tail-fully-processed case because the next iteration will do exactly the same thing, i.e., process the SACK block that contains the DSACK information.
