2011-10-31Kconfig: remove a few puzzling commentsPaul Bolle1-2/+0
These comments mention CONFIG options that do not exist: not as a symbol in a Kconfig file (without the CONFIG_ prefix) and neither as a symbol (with that prefix) in the code. There's one reference to XSCALE_PMU_TIMER as a negative dependency. But XSCALE_PMU_TIMER is never defined (CONFIG_XSCALE_PMU_TIMER is also unused in the code). It shows up with type "unknown" if you search for it in menuconfig. Apparently a negative dependency on an unknown symbol is always true. That negative dependency can be removed too.

2011-02-01ipv4: Remove fib_hash.David S. Miller1-37/+1
The time has finally come to remove the hash based routing table implementation in ipv4. FIB Trie is mature, well tested, and I've done an audit of it's code to confirm that it implements insert, delete, and lookup with the same identical semantics as fib_hash did. If there are any semantic differences found in fib_trie, we should simply fix them. I've placed the trie statistic config option under advanced router configuration. Signed-off-by: David S.

2011-01-14netfilter: fix Kconfig dependenciesPatrick McHardy1-1/+3
Fix dependencies of netfilter realm match: it depends on NET_CLS_ROUTE, which itself depends on NET_SCHED; this dependency is missing from netfilter. Since matching on realms is also useful without having NET_SCHED enabled and the option really only controls whether the tclassid member is included in route and dst entries, rename the config option to IP_ROUTE_CLASSID and move it outside of traffic scheduling context to get rid of the NET_SCHED dependeny.

2010-11-15Docs/Kconfig: Update: osdl.org -> linuxfoundation.orgMichael Witten1-1/+3
Some of the documentation refers to web pages under the domain `osdl.org'. However, `osdl.org' now redirects to `linuxfoundation.org'. Rather than rely on redirections, this patch updates the addresses appropriately; for the most part, only documentation that is meant to be current has been updated. The patch should be pretty quick to scan and check; each new web-page url was gotten by trying out the original URL in a browser and then simply copying the the redirected URL (formatting as necessary). There is some conflict as to which one of these domain names is preferred: linuxfoundation.org linux-foundation.org So, I wrote: info@linuxfoundation.org and got this reply: Message-ID: <4CE17EE6.9040807@linuxfoundation.org> Date: Mon, 15 Nov 2010 10:41:42 -0800 From: David Ames <david@linuxfoundation.org> ... linuxfoundation.org is preferred. The canonical name for our web site is www.linuxfoundation.org. Our list site is actually lists.linux-foundation.org. Regarding email linuxfoundation.org is preferred there are a few people who choose to use linux-foundation.org for their own reasons. Consequently, I used `linuxfoundation.org' for web pages and `lists.linux-foundation.org' for mailing-list web pages and email addresses; the only personal email address I updated from `@osdl.org' was that of Andrew Morton, who prefers `linux-foundation.org' according `git log'.

2010-10-03Revert "ipv4: Make INET_LRO a bool instead of tristate."Ben Hutchings1-1/+1
This reverts commit e81963b180ac502fda0326edf059b1e29cdef1a2. LRO is now deprecated in favour of GRO, and only a few drivers use it, so it is desirable to build it as a module in distribution kernels. The original change to prevent building it as a module was made in an attempt to avoid the case where some dependents are set to y and some to m, and INET_LRO can be set to m rather than y. However, the Kconfig system will reliably set INET_LRO=y in this case. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>

There is accel-pptp project (https://sourceforge.net/projects/accel-pptp/) to utilize this module, it contains plugin for pppd to use pptp in client-mode and modified pptpd (poptop) to build high-performance pptp NAS. There was many changes from initial submitted patch, most important are: 1. using rcu instead of read-write locks 2. using static bitmap instead of dynamically allocated 3. using vmalloc for memory allocation instead of BITS_PER_LONG + __get_free_pages 4. fixed many coding style issues Thanks to Eric Dumazet.

2010-04-13ipv4: ipmr: support multiple tablesPatrick McHardy1-0/+14
This patch adds support for multiple independant multicast routing instances, named "tables". Userspace multicast routing daemons can bind to a specific table instance by issuing a setsockopt call using a new option MRT_TABLE. The table number is stored in the raw socket data and affects all following ipmr setsockopt(), getsockopt() and ioctl() calls. By default, a single table (RT_TABLE_DEFAULT) is created with a default routing rule pointing to it. Newly created pimreg devices have the table number appended ("pimregX"), with the exception of devices created in the default table, which are named just "pimreg" for compatibility reasons. Packets are directed to a specific table instance using routing rules, similar to how regular routing rules work. Currently iif, oif and mark are supported as keys, source and destination addresses could be supported additionally. Example usage: - bind pimd/xorp/... to a specific table: uint32_t table = 123; setsockopt(fd, IPPROTO_IP, MRT_TABLE, &table, sizeof(table)); - create routing rules directing packets to the new table: # ip mrule add iif eth0 lookup 123 # ip mrule add oif eth0 lookup 123 Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

Now that all protocols have been made aware of the mark field it can be moved out of the union thus simplyfing its usage. The config options in the IPv4/IPv6/DECnet subsystems to enable respectively disable mark based routing only obfuscate the code with ifdefs, the cost for the additional comparison in the flow key is insignificant, and most distributions have all these options enabled by default anyway.
