Once created, an IP tunnel can't be bound to another device. (reported as https://bugzilla.redhat.com/show_bug.cgi?id=419671) To reproduce: # create a tunnel: ip tunnel add tunneltest0 mode ipip remote 10.0.0.1 dev eth0 # try to change the bounding device from eth0 to eth1: ip tunnel change tunneltest0 dev eth1 # show the result: ip tunnel show tunneltest0 tunneltest0: ip/ip remote 10.0.0.1 local any dev eth0 ttl inherit Notice the bound device has not changed from eth0 to eth1. This patch fixes it. When changing the binding, it also recalculates the MTU according to the new bound device's MTU. If the change is acceptable, I'll do the same for GRE and SIT tunnels.

RFC 4301 requires us to relookup ICMP traffic that does not match any policies using the reverse of its payload. This patch implements this for ICMP traffic that originates from or terminates on localhost. This is activated on outbound with the new policy flag XFRM_POLICY_ICMP, and on inbound by the new state flag XFRM_STATE_ICMP. On inbound the policy check is now performed by the ICMP protocol so that it can repeat the policy check where necessary. Signed-off-by:

RFC 4301 requires us to relookup ICMP traffic that does not match any policies using the reverse of its payload. This patch adds the functions xfrm_decode_session_reverse and xfrmX_policy_check_reverse so we can get the reverse flow to perform such a lookup. Signed-off-by:

This patch introduces an enum for bits in the flags argument of xfrm_lookup. This is so that we can cram more information into it later. Since all current users use just the values 0 and 1, XFRM_LOOKUP_WAIT has been added with the value 1 << 0 to represent the current meaning of flags. The test in __xfrm_lookup has been changed accordingly. Signed-off-by:

This hooks up the TFRC Loss Interval database with CCID 3 packet reception. In addition, it makes the CCID-specific computation of the first loss interval (which requires access to all the guts of CCID3) local to ccid3.c. The patch also fixes an omission in the DCCP code, that of a default / fallback RTT value (defined in section 3.4 of RFC 4340 as 0.2 sec); while at it, the upper bound of 4 seconds for an RTT sample has been reduced to match the initial TCP RTO value of 3 seconds from[RFC 1122, 4.2.3.1].

This moves two inlines back to packet_history.h: these are not private to packet_history.c, but are needed by CCID3/4 to detect whether a new loss is indicated, or whether a loss is already pending. Signed-off-by:

Each time feedback is sent two lines are printed: ccid3_hc_rx_send_feedback: client ... - entry ccid3_hc_rx_send_feedback: Interval ...usec, X_recv=..., 1/p=... The first line is redundant and thus removed. Further, documentation of ccid3_hc_rx_sock (capitalisation) is made consistent. Signed-off-by:

A ringbuffer-based implementation of loss interval history is easier to maintain, allocate, and update. The `swap' routine to keep the RX history sorted is due to and was written by Arnaldo Carvalho de Melo, simplifying an earlier macro-based variant. Details: * access to the Loss Interval Records via macro wrappers (with safety checks); * simplified, on-demand allocation of entries (no extra memory consumption on lossless links); cache allocation is local to the module / exported as service; * provision of RFC-compliant algorithm to re-compute average loss interval; * provision of comprehensive, new loss detection algorithm - support for all cases of loss, including re-ordered/duplicate packets; - waiting for NDUPACK=3 packets to fill the hole; - updating loss records when a late-arriving packet fills a hole.

This moves the inlines (which were previously declared as macros) back into packet_history.h since the loss detection code needs to be able to read entries from the RX history in order to create the relevant loss entries: it needs at least tfrc_rx_hist_loss_prev() and tfrc_rx_hist_last_rcv(), which in turn require the definition of the other inlines (macros).

This separates RX/TX initialisation and puts all packet history / loss intervals initialisation into tfrc.c. The organisation is uniform: slab declaration -> {rx,tx}_init() -> {rx,tx}_exit() Signed-off-by: -

Recently David Miller and Herbert Xu pointed out that struct net becomes overbloated and un-maintainable. There are two solutions: - provide a pointer to a network subsystem definition from struct net. This costs an additional dereferrence - place sub-system definition into the structure itself. This will speedup run-time access at the cost of recompilation time The second approach looks better for us. Other sub-systems will follow. Signed-off-by:

This patchset makes the different protocols to return an error code, so the af_inet6 module can check the initialization was correct or not. The raw6 was taken into account to be consistent with the rest of the protocols, but the registration is at the same place. Because the raw6 has its own init function, the proto and the ops structure can be moved inside the raw6.c file. Signed-off-by:

This patch makes the flowlab subsystem to return an error code and makes some cleanup with procfs ifdefs. The af_inet6 will use the flowlabel init return code to check the initialization was correct. Signed-off-by:

This includes: * moving neigh_sysctl_(un)register calls inside devinet_sysctl_(un)register ones, as they are always called in pairs; * making __devinet_sysctl_unregister() to unregister the ipv4_devconf struct, while original devinet_sysctl_unregister() works with the in_device to handle both - devconf and neigh sysctls; * make stubs for CONFIG_SYSCTL=n case to get rid of in-code ifdefs.

This cleanup shrinks size of net/core/dst.o on i386 from 1299 to 1289 bytes. (This is because dev_hold()/dev_put() are doing atomic_inc()/atomic_dec() and force compiler to re-evaluate memory contents.) Signed-off-by:
