2008-05-29tcp: Reorganize tcp_sock to fill 64-bit holes & improve localityIlpo Järvinen
I tried to group recovery related fields nearby (non-CA_Open related variables, to be more accurate) so that one to three cachelines would not be necessary in CA_Open. These are now contiguously deployed: struct sk_buff_head out_of_order_queue; /* 1968 80 */ /* --- cacheline 32 boundary (2048 bytes) --- */ struct tcp_sack_block duplicate_sack[1]; /* 2048 8 */ struct tcp_sack_block selective_acks[4]; /* 2056 32 */ struct tcp_sack_block recv_sack_cache[4]; /* 2088 32 */ /* --- cacheline 33 boundary (2112 bytes) was 8 bytes ago --- */ struct sk_buff * highest_sack; /* 2120 8 */ int lost_cnt_hint; /* 2128 4 */ int retransmit_cnt_hint; /* 2132 4 */ u32 lost_retrans_low; /* 2136 4 */ u8 reordering; /* 2140 1 */ u8 keepalive_probes; /* 2141 1 */ /* XXX 2 bytes hole, try to pack */ u32 prior_ssthresh; /* 2144 4 */ u32 high_seq; /* 2148 4 */ u32 retrans_stamp; /* 2152 4 */ u32 undo_marker; /* 2156 4 */ int undo_retrans; /* 2160 4 */ u32 total_retrans; /* 2164 4 */ ...and they're then followed by URG slowpath & keepalive related variables. Head of the out_of_order_queue always needed for empty checks, if that's empty (and TCP is in CA_Open), following ~200 bytes (in 64-bit) shouldn't be necessary for anything. If only OFO queue exists but TCP is in CA_Open, selective_acks (and possibly duplicate_sack) are necessary besides the out_of_order_queue but the rest of the block again shouldn't be (ie., the other direction had losses). As the cacheline boundaries depend on many factors in the preceeding stuff, trying to align considering them doesn't make too much sense. Commented one ordering hazard. There are number of low utilized u8/16s that could be combined get 2 bytes less in total so that the hole could be made to vanish (includes at least ecn_flags, urg_data, urg_mode, frto_counter, nonagle).

2008-05-22netlink: Fix nla_parse_nested_compat() to call nla_parse() directlyThomas Graf
The purpose of nla_parse_nested_compat() is to parse attributes which contain a struct followed by a stream of nested attributes. So far, it called nla_parse_nested() to parse the stream of nested attributes which was wrong, as nla_parse_nested() expects a container attribute as data which holds the attribute stream. It needs to call nla_parse() directly while pointing at the next possible alignment point after the struct in the beginning of the attribute. With this patch, I can no longer reproduce the reported leftover warnings. Signed-off-by: Thomas Graf <tgraf@suug.ch> Acked-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-05-22uli526x: add support for netpollAnton Vorontsov
This patch adds netpoll support for the uli526x ethernet driver -- simply call the interrupt handler for polling. To do this without disable_irq()/enable_irq() pair we should fully protect the handler. Luckily, it's already using irqsave spinlock, the only unprotected place is interrupts re-enabling write. It was safe to re-enable interrupts without holding the spinlock, but with netpoll possibility now it doesn't seem so. Patch was tested using netconsole and KGDBoE.

2008-05-22[SC92031] Using padto turned driver into an IPv6-only interfaceGerrit Renker
IPv4 would work with this driver only with static arp table entries, the patch reverts a padto introduced in commit 26a17b7bbb36a8552d531bc1ad08472fb5aa3007 sc92031: start transmit return value bugfix The padto does not work because the driver code evaluates `len' later on and there are cases where skb->len is not updated accordingly. This was observed with ARP frames (skb->len = 42 bytes, !skb_cloned(), skb_tailroom = 84 bytes). Then in skb_pad(), the first condition is true, where skb->len is not updated. As a consequence, the driver uses 42 bytes instead of the 60 bytes, and the ARP frame never makes it onto the wire.
