2006-01-17[PKTGEN]: Replacing with (compare|is_zero)_ether_addr() and ETH_ALENKris Katterjohn1-23/+11
This replaces some tests with is_zero_ether_addr(), memcmp(one, two, 6) with compare_ether_addr(one, two), and 6 with ETH_ALEN where appropriate. Signed-off-by: Kris Katterjohn <kjak@users.sourceforge.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-01-17[IPV4]: rt_cache_stat can be statically definedEric Dumazet1-10/+4
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.

2006-01-17[PKT_SCHED] sch_prio: fix qdisc bands initAmnon Aaronsohn1-4/+3
Currently when PRIO is configured to use N bands, it lets the packets be directed to any of the bands 0..N-1. However, PRIO attaches a fifo qdisc only to the bands that appear in the priomap; the rest of the N bands remain with a noop qdisc attached. This patch changes PRIO's behavior so that it attaches a fifo qdisc to all of the N bands. Signed-off-by: Amnon Aaronsohn <bla@cs.huji.ac.il> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-01-14x86: Work around compiler code generation bug with -OsLinus Torvalds1-3/+3
Some versions of gcc generate incorrect code for the inet_check_attr() function, apparently due to a totally bogus index -> pointer comparison transformation. At least "gcc version 4.0.1 20050727 (Red Hat 4.0.1-5)" from FC4 is affected, possibly others too. This changes the function subtly so that the buggy gcc transformation doesn't trigger.

2006-01-13[XFRM]: IPsec tunnel wildcard address supportPatrick McHardy2-0/+32
When the source address of a tunnel is given as 0.0.0.0 do a routing lookup to get the real source address for the destination and fill that into the acquire message. This allows to specify policies like this: spdadd 172.16.128.13/32 172.16.0.0/20 any -P out ipsec esp/tunnel/0.0.0.0-x.x.x.x/require; spdadd 172.16.0.0/20 172.16.128.13/32 any -P in ipsec esp/tunnel/x.x.x.x-0.0.0.0/require; Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2006-01-13[PATCH] genetlink: don't touch module ref countPer Liden2-8/+0
Increasing the module ref count at registration will block the module from ever being unloaded. In fact, genetlink should not care about the owner at all.

2006-01-12[NETFILTER] x_tables: Abstraction layer for {ip,ip6,arp}_tablesHarald Welte98-3446/+2646
This monster-patch tries to do the best job for unifying the data structures and backend interfaces for the three evil clones ip_tables, ip6_tables and arp_tables. In an ideal world we would never have allowed this kind of copy+paste programming... but well, our world isn't (yet?) ideal. o introduce a new x_tables module o {ip,arp,ip6}_tables depend on this x_tables module o registration functions for tables, matches and targets are only wrappers around x_tables provided functions o all matches/targets that are used from ip_tables and ip6_tables are now implemented as xt_FOOBAR.c files and provide module aliases to ipt_FOOBAR and ip6t_FOOBAR o header files for xt_matches are in include/linux/netfilter/, include/linux/netfilter_{ipv4,ipv6} contains compatibility wrappers around the xt_FOOBAR.h headers Based on this patchset we're going to further unify the code, gradually getting rid of all the layer 3 specific assumptions.

2006-01-11[IPV6]: Avoid calling ip6_xmit() with NULL skDavid Woodhouse1-2/+18
The ip6_xmit() function now assumes that its sk argument is non-NULL, which isn't currently true when TCPv6 code is sending RST or ACK packets. This fixes that code to use a socket of its own for sending such packets, as TCPv4 does. (Thanks Andi for the pointer). Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: David S.

With non-linear skbs however the pointers may point to two seperate buffers on the stack and the calculation results in a wrong offset beeing used.
