* net: Convert printks to pr_<level>Joe Perches2012-03-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Use a more current kernel messaging style. Convert a printk block to print_hex_dump. Coalesce formats, align arguments. Use %s, __func__ instead of embedding function names. Some messages that were prefixed with <foo>_close are now prefixed with <foo>_fini. Some ah4 and esp messages are now not prefixed with "ip ". The intent of this patch is to later add something like #define pr_fmt(fmt) "IPv4: " fmt. to standardize the output messages. Text size is trivially reduced.

* ipv4: Cache source address in nexthop entries.David S. Miller2011-03-081-7/+24
| | | | | | | | | | | | | | | | | | | When doing output route lookups, we have to select the source address if the user has not specified an explicit one. First, if the route has an explicit preferred source address specified, then we use that. Otherwise we search the route's outgoing interface for a suitable address. This search can be precomputed and cached at route insertion time. The only missing part is that we have to refresh this precomputed value any time addresses are added or removed from the interface, and this is accomplished by fib_update_nh_saddrs().

* ipv4: Validate route entry type at insert instead of every lookup.David S. Miller2011-03-071-26/+28
| | | | | | | | | | | | | | | fib_semantic_match() requires that if the type doesn't signal an automatic error, it must be of type RTN_UNICAST, RTN_LOCAL, RTN_BROADCAST, RTN_ANYCAST, or RTN_MULTICAST. Checking this every route lookup is pointless work. Instead validate it during route insertion, via fib_create_info(). Also, there was nothing making sure the type value was less than RTN_MAX, so add that missing check while we're here. Signed-off-by: David S. Miller <davem@davemloft.net>

* ipv4: Consolidate all default route selection implementations.David S. Miller2011-02-011-0/+56
| | | | | | | | | | | | | | | | | | | Both fib_trie and fib_hash have a local implementation of fib_table_select_default(). This is completely unnecessary code duplication. Since we now remember the fib_table and the head of the fib alias list of the default route, we can implement one single generic version of this routine. Looking at the fib_hash implementation you may get the impression that it's possible for there to be multiple top-level routes in the table for the default route. The truth is, it isn't, the insert code will only allow one entry to exist in the zero prefix hash table, because all keys evaluate to zero and all keys in a hash table must be unique.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* netlink: change nlmsg_notify() return value logicPablo Neira Ayuso2009-02-251-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the return value of nlmsg_notify() as follows: If NETLINK_BROADCAST_ERROR is set by any of the listeners and an error in the delivery happened, return the broadcast error; else if there are no listeners apart from the socket that requested a change with the echo flag, return the result of the unicast notification. Thus, with this patch, the unicast notification is handled in the same way of a broadcast listener that has set the NETLINK_BROADCAST_ERROR socket flag. This patch is useful in case that the caller of nlmsg_notify() wants to know the result of the delivery of a netlink notification (including the broadcast delivery) and take any action in case that the delivery failed. For example, ctnetlink can drop packets if the event delivery failed to provide reliable logging and state-synchronization at the cost of dropping packets. This patch also modifies the rtnetlink code to ignore the return value of rtnl_notify() in all callers. The function rtnl_notify() (before this patch) returned the error of the unicast notification which makes rtnl_set_sk_err() reports errors to all listeners. This is not of any help since the origin of the change (the socket that requested the echoing) notices the ENOBUFS error if the notification fails and should resync itself.

The codepath inside is completely different, so lets separate it into two calls for these two cases. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S.

* [NETNS]: Pass correct namespace in context fib_check_nh.Denis V. Lunev2008-01-291-6/+6
| | | | | | | | | Correct network namespace is already used in fib_check_nh. Re-work its usage for better readability and pass into fib_lookup & inetdev_by_index. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* [NETNS]: Add netns to nl_info structure.Denis V. Lunev2008-01-291-6/+10
| | | | | | | | | | | nl_info is used to track the end-user destination of routing change notification. This is a natural object to hold a namespace on. Place it there and utilize the context in the appropriate places. Acked-by: Benjamin Thery <benjamin.thery@bull.net> Acked-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: Denis V.

* [NETNS]: Add netns parameter to inet_(dev_)add_type.Eric W. Biederman2008-01-291-2/+2
| | | | | | | | | | | | | | | The patch extends the inet_addr_type and inet_dev_addr_type with the network namespace pointer. That allows to access the different tables relatively to the network namespace. The modification of the signature function is reported in all the callers of the inet_addr_type using the pointer to the well known init_net.
