* [NETLINK]: Don't BUG on undersized allocationsPatrick McHardy2007-02-08
| | | | | | | | | | | | | | | Currently netlink users BUG when the allocated skb for an event notification is undersized. While this is certainly a kernel bug, its not critical and crashing the kernel is too drastic, especially when considering that these errors have appeared multiple times in the past and it BUGs even if no listeners are present. This patch replaces BUG by WARN_ON and changes the notification functions to inform potential listeners of undersized allocations using a unique error code (EMSGSIZE).

* [XFRM]: Use output device disable_xfrm for forwarded packetsPatrick McHardy2006-12-06
| | | | | | | | | | | | | | | Currently the behaviour of disable_xfrm is inconsistent between locally generated and forwarded packets. For locally generated packets disable_xfrm disables the policy lookup if it is set on the output device, for forwarded traffic however it looks at the input device. This makes it impossible to disable xfrm on all devices but a dummy device and use normal routing to direct traffic to that device. Always use the output device when checking disable_xfrm.

* [NET]: Rethink mark field in struct flowiThomas Graf2006-12-03
| | | | | | | | | | | | | | | | | | 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. Therefore it makes sense to remove the config options and enable mark based routing by default. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

* [IPV4]: Limit rt cache size properly.Kirill Korotaev2006-08-07
| | | | | | | | | | | | | | | | | | | From: Kirill Korotaev <dev@sw.ru> During OpenVZ stress testing we found that UDP traffic with random src can generate too much excessive rt hash growing leading finally to OOM and kernel panics. It was found that for 4GB i686 system (having 1048576 total pages and 225280 normal zone pages) kernel allocates the following route hash: syslog: IP route cache hash table entries: 262144 (order: 8, 1048576 bytes) => ip_rt_max_size = 4194304 entries, i.e. max rt size is 4194304 * 256b = 1Gb of RAM > normal_zone Attached the patch which removes HASH_HIGHMEM flag from alloc_large_system_hash() call.

* [PATCH] Define __raw_get_cpu_var and use itPaul Mackerras2006-06-25
| | | | | | | | | | | | | | | | | | | | | | | There are several instances of per_cpu(foo, raw_smp_processor_id()), which is semantically equivalent to __get_cpu_var(foo) but without the warning that smp_processor_id() can give if CONFIG_DEBUG_PREEMPT is enabled. For those architectures with optimized per-cpu implementations, namely ia64, powerpc, s390, sparc64 and x86_64, per_cpu() turns into more and slower code than __get_cpu_var(), so it would be preferable to use __get_cpu_var on those platforms. This defines a __raw_get_cpu_var(x) macro which turns into per_cpu(x, raw_smp_processor_id()) on architectures that use the generic per-cpu implementation, and turns into __get_cpu_var(x) on the architectures that have an optimized per-cpu implementation.

* [IPV4]: Aggregate route entries with different TOS valuesIlia Sotnikov2006-03-25
| | | | | | | | | | | | | | | | | | | | | | | When we get an ICMP need-to-frag message, the original TOS value in the ICMP payload cannot be used as a key to look up the routes to update. This is because the TOS field may have been modified by routers on the way. Similarly, ip_rt_redirect should also ignore the TOS as the router that gave us the message may have modified the TOS value. The patch achieves this objective by aggregating entries with different TOS values (but are otherwise identical) into the same bucket. This makes it easy to update them at the same time when an ICMP message is received. In future we should use a twin-hashing scheme where teh aggregation occurs at the entry level. That is, the TOS goes back into the hash for normal lookups while ICMP lookups will end up with a node that gives us a list that contains all other route entries that differ only by TOS.

* [IPV4]: rt_cache_stat can be statically definedEric Dumazet2006-01-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using __get_cpu_var(obj) is slightly faster than per_cpu_ptr(obj, raw_smp_processor_id()). 1) Smaller code and memory use For static and small objects, DEFINE_PER_CPU(type, object) is preferred over a alloc_percpu() : Better and smaller code to access them, and no extra memory (storing the pointer, and the percpu array of pointers) x86_64 code before patch mov 1237577(%rip),%rax # ffffffff803e5990 <rt_cache_stat> not %rax # part of per_cpu machinery mov %gs:0x3c,%edx # get cpu number movslq %edx,%rdx # extend 32 bits cpu number to 64 bits mov (%rax,%rdx,8),%rax # get the pointer for this cpu incl 0x38(%rax) x86_64 code after patch mov $per_cpu__rt_cache_stat,%rdx mov %gs:0x48,%rax # get percpu data offset incl 0x38(%rax,%rdx,1) 2) False sharing avoidance for SMP : For a small NR_CPUS, the array of per cpu pointers allocated in alloc_percpu() can be <= 32 bytes. This let slab code gives a part of a cache line. If the other part of this 64 bytes (or 128 bytes) cache line is used by a mostly written object, we can have false sharing and expensive per_cpu_ptr() operations. Size of rt_cache_stat is 64 bytes, so this patch is not a danger of a too big increase of bss (in UP mode) or static per_cpu data for SMP (PERCPU_ENOUGH_ROOM is currently 32768 bytes) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

* [IPV4] tcp/route: Another look at hash table sizesMike Stroyan2005-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tcp_ehash hash table gets too big on systems with really big memory. It is worse on systems with pages larger than 4KB. It wastes memory that could be better used. It also makes the netstat command slow because reading /proc/net/tcp and /proc/net/tcp6 needs to go through the full hash table. The default value should not be larger for larger page sizes. It seems that the effect of page size is an unintended error dating back a long time. I also wonder if the default value really should be a larger fraction of memory for systems with more memory. While systems with really big ram can afford more space for hash tables, it is not clear to me that they benefit from increasing the allocation ratio for this table. The amount of memory allocated is determined by net/ipv4/tcp.c:tcp_init and mm/page_alloc.c:alloc_large_system_hash. tcp_init calls alloc_large_system_hash passing parameters- bucketsize=sizeof(struct tcp_ehash_bucket) numentries=thash_entries scale=(num_physpages >= 128 * 1024) ? (25-PAGE_SHIFT) : (27-PAGE_SHIFT) limit=0 On i386, PAGE_SHIFT is 12 for a page size of 4K On ia64, PAGE_SHIFT defaults to 14 for a page size of 16K The num_physpages test above makes the allocation take a larger fraction of the total memory on systems with larger memory. The threshold size for a i386 system is 512MB. For an ia64 system with 16KB pages the threshold is 2GB. For smaller memory systems- On i386, scale = (27 - 12) = 15 On ia64, scale = (27 - 14) = 13 For larger memory systems- On i386, scale = (25 - 12) = 13 On ia64, scale = (25 - 14) = 11 For the rest of this discussion, I'll just track the larger memory case. The default behavior has numentries=thash_entries=0, so the allocated size is determined by either scale or by the default limit of 1/16 of total memory. In alloc_large_system_hash- | numentries = (flags & HASH_HIGHMEM) ? nr_all_pages : nr_kernel_pages; | numentries += (1UL << (20 - PAGE_SHIFT)) - 1; | numentries >>= 20 - PAGE_SHIFT; | numentries <<= 20 - PAGE_SHIFT; At this point, numentries is pages for all of memory, rounded up to the nearest megabyte boundary. | /* limit to 1 bucket per 2^scale bytes of low memory */ | if (scale > PAGE_SHIFT) | numentries >>= (scale - PAGE_SHIFT); | else | numentries <<= (PAGE_SHIFT - scale); On i386, numentries >>= (13 - 12), so numentries is 1/8196 of bytes of total memory. On ia64, numentries <<= (14 - 11), so numentries is 1/2048 of bytes of total memory. | log2qty = long_log2(numentries); | | do { | size = bucketsize << log2qty; bucketsize is 16, so size is 16 times numentries, rounded down to a power of two. On i386, size is 1/512 of bytes of total memory. On ia64, size is 1/128 of bytes of total memory. For smaller systems the results are On i386, size is 1/2048 of bytes of total memory. On ia64, size is 1/512 of bytes of total memory. The large page effect can be removed by just replacing the use of PAGE_SHIFT with a constant of 12 in the calls to alloc_large_system_hash. That makes them more like the other uses of that function from fs/inode.c and fs/dcache.c Signed-off-by: David S. Miller <davem@davemloft.net>

* [NETLINK]: Correctly set NLM_F_MULTI without checking the pidJamal Hadi Salim2005-06-19
