1) Cleanups (all functions are prefixed by sock_prot_inuse) sock_prot_inc_use(prot) -> sock_prot_inuse_add(prot,-1) sock_prot_dec_use(prot) -> sock_prot_inuse_add(prot,-1) sock_prot_inuse() -> sock_prot_inuse_get() New functions : sock_prot_inuse_init() and sock_prot_inuse_free() to abstract pcounter use. 2) if CONFIG_PROC_FS=n, we can zap 'inuse' member from "struct proto", since nobody wants to read the inuse value. This saves 1372 bytes on i386/SMP and some cpu cycles. Signed-off-by:

Before pushing pcounter to Linus tree, I would like to make some adjustments. Goal is to reduce kernel text size, by unlining too big functions. When a pcounter is bound to a statically defined per_cpu variable, we define two small helpers functions. (No more folding function using the fat for_each_possible_cpu(cpu) ... ) static DEFINE_PER_CPU(int, NAME##_pcounter_values); static void NAME##_pcounter_add(struct pcounter *self, int val) { __get_cpu_var(NAME##_pcounter_values) += val; } static int NAME##_pcounter_getval(const struct pcounter *self, int cpu) { return per_cpu(NAME##_pcounter_values, cpu); } Fast path is therefore unchanged, while folding/alloc/free is now unlined. This saves 228 bytes on i386 Signed-off-by: -

We can void divides (as seen with CONFIG_CC_OPTIMIZE_FOR_SIZE=y on x86) changing ((HZ<<idx)/4) to ((HZ/4) << idx) Signed-off-by:

In case of segments which are purely for control without any data (SYN/ACK/FIN/RST), many fields are set to common values in multiple places. i386 results: $ gcc --version gcc (GCC) 4.1.2 20070626 (Red Hat 4.1.2-13) $ codiff tcp_output.o.old tcp_output.o.new net/ipv4/tcp_output.c: tcp_xmit_probe_skb | -48 tcp_send_ack | -56 tcp_retransmit_skb | -79 tcp_connect | -43 tcp_send_active_reset | -35 tcp_make_synack | -42 tcp_send_fin | -48 7 functions changed, 351 bytes removed net/ipv4/tcp_output.c: tcp_init_nondata_skb | +90 1 function changed, 90 bytes added tcp_output.o.mid: 8 functions changed, 90 bytes added, 351 bytes removed, diff: -261 Signed-off-by:

Removed case indentation level & combined some nested ifs, mostly within 80 lines now. This is a leftover from indent patch, it just had to be done manually to avoid messing it up completely. Signed-off-by:

Previously we made it an error on the output path if the sequence number overflowed. However we did not set the err variable accordingly. This patch sets err to -EOVERFLOW in that case. Signed-off-by:

[IPVS]: Remove declaration of unimplemented method and remove unused definition from include/net/ip_vs.h In include/net/ip_vs.h: - The ip_vs_secure_tcp_set() method is not implemented anywhere. - IP_VS_APP_TYPE_FTP is an unused definition. Signed-off-by:

These three declarations in include/net/ip.h are not implemented anywhere: ip_mc_dropsocket(), ip_mc_dropdevice() and ip_net_unreachable(). Also, correct a comment to be "Functions provided by ip_fragment.c" (instead of by ip_fragment.o) in consistency with the other comments in this header. Signed-off-by:

These were manually selected from indent's results which as is are too noisy to be of any use without human reason. In addition, some extra newlines between function and its comment were removed too. Signed-off-by:

The snd_up check should be enough. I suspect this has been there to provide a minor optimization in clean_rtx_queue which used to have a small if (!->sacked) block which could skip snd_up check among the other work. Signed-off-by:

SACK reneging can be precalculated to a FLAG in clean_rtx_queue which has the right skb looked up. This will help a bit in future because skb->sacked access will be changed eventually, changing it already won't hurt any. Signed-off-by:

Earlier resolution for NewReno's sacked_out should now keep it small enough for this to become invariant-like check. Signed-off-by:

This patch introduces new memory accounting functions for each network protocol. Most of them are renamed from memory accounting functions for stream protocols. At the same time, some stream memory accounting functions are removed since other functions do same thing. Renaming: sk_stream_free_skb() -> sk_wmem_free_skb() __sk_stream_mem_reclaim() -> __sk_mem_reclaim() sk_stream_mem_reclaim() -> sk_mem_reclaim() sk_stream_mem_schedule -> __sk_mem_schedule() sk_stream_pages() -> sk_mem_pages() sk_stream_rmem_schedule() -> sk_rmem_schedule() sk_stream_wmem_schedule() -> sk_wmem_schedule() sk_charge_skb() -> sk_mem_charge() Removeing sk_stream_rfree(): consolidates into sock_rfree() sk_stream_set_owner_r(): consolidates into skb_set_owner_r() sk_stream_mem_schedule() The following functions are added. sk_has_account(): check if the protocol supports accounting sk_mem_uncharge(): do the opposite of sk_mem_charge() In addition, to achieve consolidation, updating sk_wmem_queued is removed from sk_mem_charge(). Next, to consolidate memory accounting functions, this patch adds memory accounting calls to network core functions. Moreover, present memory accounting call is renamed to new accounting call. Finally we replace present memory accounting calls with new interface in TCP and SCTP. Signed-off-by: -

When netfilter is off the transport-mode async resumption doesn't work because we don't push back the IP header. This patch fixes that by moving most of the code outside of ifdef NETFILTER since the only part that's not common is the short-circuit in the protocol handler. Signed-off-by:
