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:

The following patch create the usual static inline functions to disable the xfrm6_init and xfrm6_fini function when XFRM is off. That's allow to remove some ifdef and make the code a little more clear. Signed-off-by:

Make the proc creation/destruction to be a separate function. That allows to remove the #ifdef CONFIG_PROC_FS in the init/fini function and make them more readable. 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:

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:

The SNMP_INC_STATS_OFFSET_BH is used only by ICMP6_INC_STATS_OFFSET_BH. The ICMP6_INC_STATS_OFFSET_BH is unused. Signed-off-by:

single list_head variable initialized with LIST_HEAD_INIT could almost always can be replaced with LIST_HEAD declaration, this shrinks the code and looks better. Signed-off-by:

We only use these variables when displaying the trie in proc so place them into the iterator to make this explicit. We should probably do something smarter to handle the CONFIG_IP_MULTIPLE_TABLES case but at least this makes it clear that the silliness is limited to the display in /proc. Signed-off-by:

There are only 2 users and it doesn't hurt to call fib_get_table instead, and it makes it easier to make the fib network namespace aware. Signed-off-by:

If the kmem_cache_creation fails, the kernel will panic. It is acceptable if the system is booting, but if the ipv6 protocol is compiled as a module and it is loaded after the system has booted, do we want to panic instead of just failing to initialize the protocol ? The init function is now returning an error and this one is checked for protocol initialization. So the ipv6 protocol will safely fails. Signed-off-by:

The af_inet6 initialization function does not check the return code of the route initilization, so if something goes wrong, the protocol initialization will continue anyway. This patch takes into account the modification made in the different route's initialization subroutines to check the return value and to make the protocol initialization to fail. Signed-off-by:

Daniel Lezcano authored
The route initialization function does not return any value to notify if the initialization is successful or not. This patch checks all calls made for the initilization in order to return a value for the caller. Unfortunately, proc_net_fops_create will return a NULL pointer if CONFIG_PROC_FS is off, so we can not check the return code without an ifdef CONFIG_PROC_FS block in the ip6_route_init function.

When the fib_rules initialization finished, no return code is provided so there is no way to know, for the caller, if the initialization has been successful or has failed. This patch fix that. Signed-off-by:

The xfrm initialization function does not return any error code, so if there is an error, the caller can not be advise of that. This patch checks the return code of the different called functions in order to return a successful or failed initialization. Signed-off-by:

If there is an error in the initialization function, nothing is followed up to the caller. So I add a return value to be set for the init function. Signed-off-by:

Credit here goes to Gerrit Renker, that provided the initial implementation for this new codebase. I modified it just to try to make it closer to the existing API, renaming some functions, add namespacing and fix one bug where the tfrc_rx_hist_alloc was not freeing the allocated ring entries on the error path. Original changeset comment from Gerrit: ----------- This provides a new, self-contained and generic RX history service for TFRC based protocols. Details: * new data structure, initialisation and cleanup routines; * allocation of dccp_rx_hist entries local to packet_history.c, as a service exported by the dccp_tfrc_lib module. * interface to automatically track highest-received seqno; * receiver-based RTT estimation (needed for instance by RFC 3448, 6.3.1); * a generic function to test for `data packets' as per RFC 4340, sec. 7.7.

This patch changes the tfrc_lib module in the following manner: (1) a dedicated tfrc source file to call the packet history & loss interval init/exit functions. (2) a dedicated tfrc_pr_debug macro with toggle switch `tfrc_debug'. Commiter note: renamed tfrc_module.c to tfrc.c, and made CONFIG_IP_DCCP_CCID3 select IP_DCCP_TFRC_LIB. Signed-off-by: -

The same cleanup for deletion requests. Signed-off-by:

Pavel Emelyanov authored
The ATF_PUBL requests are handled completely separate from the others. Emphasize it with a separate function. This also reduces the indentation level. The same issue exists with the arp_delete_request, but when I tried to make it in one patch diff produced completely unreadable patch. So I split it into two, but they may be done with one commit.

The rt_cache, stats/rt_cache and rt_acct(optional) files creation looks a bit messy. Clean this out and join them to other proc-related functions under the proper ifdef. The struct net * argument in a new function will help net namespaces patches look nicer. Signed-off-by:

The net/ipv4/route.c file declares some entries for proc to dump some routing info. The reading functions are scattered over this file - collect them together. Besides, remove a useless IP_RT_ACCT_CPU macro. Signed-off-by:

The previous move of the the UDP inDatagrams counter caused each peek of the same packet to be counted separately. This may be undesirable. This patch fixes this by adding a bit to sk_buff to record whether this packet has already been seen through skb_recv_datagram. We then only increment the counter when the packet is seen for the first time. The only dodgy part is the fact that skb_recv_datagram doesn't have a good way of returning this new bit of information. So I've added a new function __skb_recv_datagram that does return this and made skb_recv_datagram a wrapper around it. The plan is to eventually replace all uses of skb_recv_datagram with this new function at which time it can be renamed its proper name. Signed-off-by:

The previous move of the the UDP inDatagrams counter caused the counting of encapsulated packets, SUNRPC data (as opposed to call) packets and RXRPC packets to go missing. This patch restores all of these. Signed-off-by:

Currently it is possible for two processes to peek on the same socket and end up incrementing the error counter twice for the same packet. This patch fixes it by making skb_kill_datagram return whether it succeeded in unlinking the packet and only incrementing the counter if it did. Signed-off-by:
