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 inet6_register_protosw to return an error code. The different protocols can be aware the registration was successful or not and can pass the error to the initial caller, af_inet6. Signed-off-by:

This patch factorize the code for the differents init functions for rthdr, nodata, destopt in a single function exthdrs_init. This function returns an error so the af_inet6 module can check correctly the initialization. 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.

The sizeof(struct tcp_skb_cb) should not be less than the sizeof(skb->cb). This is checked in net/ipv4/tcp.c, but this check can be made more gracefully. Signed-off-by:

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:

This patch adds the xfrm_input_state helper function which returns the current xfrm state being processed on the input path given an sk_buff. This is currently only used by xfrm_input but will be used by ESP upon asynchronous resumption. Signed-off-by:

The patch defines the usual static inline functions when the code is disabled for fib6_rules. That's allow to remove some ifdef in route.c file and make the code a little more clear. Signed-off-by:

Just move the variable on the struct net and adjust its usage. Others sysctls from sys.net.core table are more difficult to virtualize (i.e. make them per-namespace), but I'll look at them as well a bit later. Signed-off-by:

Some of ctl variables are going to be on the struct net. Here's the way to adjust the ->data pointer on the ctl_table-s to point on the right variable. Since some pointers still point on the global variables, I keep turning the write bits off on such tables. This looks to become a common procedure for net sysctls, so later parts of this code may migrate to some more generic place. Signed-off-by:

Pavel Emelyanov authored
Making them per-namespace is required for the following two reasons: First, some ctl values have a per-namespace meaning. Second, making them writable from the sub-namespace is an isolation hole. So I introduce the pernet operations to create these tables. For init_net I use the existing statically declared tables, for sub-namespace they are duplicated and the write bits are removed from the mode. Signed-off-by:
