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:

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.

There's no need in having this function exist in a form of macro. Properly formatted function looks much better. Signed-off-by:

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:

The only difference in this case is that updating all.forwarding causes the update in default.forwarding when done via proc, but not via the system call. Besides, this consolidates a good portion of code. Signed-off-by:
-
Pavel Emelyanov authored
AFAIS these two entries should do the same thing - change the forwarding state on ipv4_devconf and on all the devices. I propose to merge the handlers together using ctl paths. The inet_forward_change() is static after this and I move it higher to be closer to other "propagation" helpers and to avoid diff making patches based on { and } matching :) i.e. - make them easier to read.

I have already done this for core, ipv4 and tr tables, so repeat this for the ipv6 ones. This makes the ipv6.ko smaller and creates the ground needed for net namespaces support in ipv6.ko ssctls. Signed-off-by:

Since this file is entirely enclosed with the #ifdef CONFIG_SYSCTL/#endif pair, it's OK to move this CONFIG_ into a Makefile. Signed-off-by:

I have removed all the entries from this table (core_table, ipv4_table and tr_table), so now we can safely drop it. Signed-off-by:

Pavel Emelyanov authored
The same thing for token-ring - use ctl paths and get rid of external references on the tr_table. Unfortunately, I couldn't split this patch into cleanup and use-the-paths parts. As a lame excuse I can say, that the cleanup is just moving the tr_table from one file to another - closet to a single variable, that this ctl table tunes. Since the source file becomes empty after the move, I remove it. Signed-off-by:

This is the same as I did for the net/core/ table in the second patch in his series: use the paths and isolate the whole table in the .c file. Signed-off-by:
-
Pavel Emelyanov authored
This includes several cleanups: * tune Makefile to compile out this file when SYSCTL=n. Now it looks like net/core/sysctl_net_core.c one; * move the ipv4_config to af_inet.c to exist all the time; * remove additional sysctl_ip_nonlocal_bind declaration (it is already declared in net/ip.h); * remove no nonger needed ifdefs from this file. This is a preparation for using ctl paths for net/ipv4/ sysctl table. Signed-off-by:

Pavel Emelyanov authored
Using ctl paths we can put all the stuff, related to net/core/ sysctl table, into one file and remove all the references on it. As a good side effect this hides the "core_table" name from the global scope :) Signed-off-by:

Pavel Emelyanov authored
This file is already compiled out when the SYSCTL=n, so these ifdefs, that enclose the whole file, can be removed. Signed-off-by:

Remove the NF_CONNTRACK_ENABLED option. It was meant for a smoother upgrade to nf_conntrack, people having reconfigured their kernel at least once since ip_conntrack was removed will have the NF_CONNTRACK option already set. People upgrading from older kernels have to reconfigure a lot anyway. Signed-off-by:
