Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[NET_SCHED]: Cleanup L2T macros and handle oversized packets Change L2T (length to time) macros, in all rate based schedulers, to call a common function qdisc_l2t() that does the rate table lookup. This function handles if the packet size lookup is larger than the rate table, which often occurs with TSO enabled.

[PKT_SCHED]: Kill pkt_act.h inlining. This was simply making templates of functions and mostly causing a lot of code duplication in the classifier action modules. We solve this more cleanly by having a common "struct tcf_common" that hash worker functions contained once in act_api.c can work with. Callers work with real action objects that have the common struct plus their module specific struct members. You go from a common object to the higher level one using a "to_foo()" macro which makes use of container_of() to do the dirty work. This also kills off act_generic.h which was only used by act_simple.c and keeping it around was more work than the it's value. Signed-off-by: David S. Miller <davem@davemloft.net>

[NET_SCHED]: policer: restore compatibility with old iproute binaries The tc actions increased the size of struct tc_police, which broke compatibility with old iproute binaries since both the act_police and the old NET_CLS_POLICE code check for an exact size match. Since the new members are not even used, the simple fix is to also accept the size of the old structure. Dumping is not affected since old userspace will receive a bigger structure, which is handled fine.

We solve this more cleanly by having a common "struct tcf_common" that hash worker functions contained once in act_api.c can work with. Callers work with real action objects that have the common struct plus their module specific struct members. You go from a common object to the higher level one using a "to_foo()" macro which makes use of container_of() to do the dirty work. This also kills off act_generic.h which was only used by act_simple.c and keeping it around was more work than the it's value. Signed-off-by: David S. Miller <davem@davemloft.net>

[SK_BUFF]: Convert skb->tail to sk_buff_data_t So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

[PKT_SCHED]: Kill pkt_act.h inlining. This was simply making templates of functions and mostly causing a lot of code duplication in the classifier action modules. We solve this more cleanly by having a common "struct tcf_common" that hash worker functions contained once in act_api.c can work with. Callers work with real action objects that have the common struct plus their module specific struct members. You go from a common object to the higher level one using a "to_foo()" macro which makes use of container_of() to do the dirty work. This also kills off act_generic.h which was only used by act_simple.c and keeping it around was more work than the it's value. Signed-off-by: David S. Miller <davem@davemloft.net>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
