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:

The queueing core doesn't care about the exact return value from the queue handler, so there's no need to go through the trouble of returning a meaningful value as long as we indicate an error. Signed-off-by:

We don't need a default case in nfqnl_build_packet_message(), the copy_mode is validated when it is set. Tell the compiler about the possible types and remove the default case. Saves 80b of text on x86_64. Signed-off-by:

nfqnl_set_mode takes the queue lock and calls __nfqnl_set_mode. Just move the code from __nfqnl_set_mode to nfqnl_set_mode since there is no other user. Signed-off-by:

Use RCU for queue instances hash. Avoids multiple atomic operations for each packet. Signed-off-by:

Patrick McHardy authored
The peer_pid must be checked in all cases when a queue exists, currently it is not checked if for NFQA_CFG_QUEUE_MAXLEN when a NFQA_CFG_CMD attribute exists in some cases. Same for the queue existance check, which can cause a NULL pointer dereference. Also consistently return -ENODEV for "queue not found". -ENOENT would be better, but that is already used to indicate a queued skb id doesn't exist. Signed-off-by:

The sequence counter doesn't need to be an atomic_t, just move the increment inside the locked section. Signed-off-by:
