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:

Add __acquires() and __releases() annotations to suppress some sparse warnings. example of warnings : net/ipv4/udp.c:1555:14: warning: context imbalance in 'udp_seq_start' - wrong count at exit net/ipv4/udp.c:1571:13: warning: context imbalance in 'udp_seq_stop' - unexpected unlock 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:

For five years we had two xfrm_policy_flush prototypes and every time that function's signature changed people have been diligently updating both of them without noticing :) Signed-off-by:

Avoid an expensive divide (as done in commit 18030477e70a826b91608aee40a987bbd368fec6 but lost in commit 23821d2653111d20e75472c8c5003df1a55309a8) 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:

There's very little need to have the packets_out incrementing in a separate function. Also name the combined function appropriately. 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: -

Let's nip the code duplication in the bud :) 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:

When the output transform returns EINPROGRESS due to async operation we'll free the skb the straight away as if it were an error. This patch fixes that so that the skb is freed when the async operation completes. Signed-off-by:

If snd_wnd - snd_nxt wasn't multiple of MSS, skb was split on odd boundary by the callers of tcp_window_allows. We try really hard to avoid unnecessary modulos. Therefore the old caller side check "if (skb->len < limit)" was too wide as well because limit is not bound in any way to skb->len and can cause spurious testing for trimming in the middle of the queue while we only wanted that to happen at the tail of the queue. A simple additional caller side check for tcp_write_queue_tail would likely have resulted 2 x modulos because the limit would have to be first calculated from window, however, doing that unnecessary modulo is not mandatory. After a minor change to the algorithm, simply determine first if the modulo is needed at all and at that point immediately decide also from which value it should be calculated from. This approach also kills some duplicated code. Signed-off-by:

print_mac() used many most net drivers and format_addr() used by net-sysfs.c are very similar and they can be intergrated. format_addr() is also identically redefined in the qla4xxx iscsi driver. Export a new function sysfs_format_mac() to be used by net-sysfs, qla4xxx and others in the future. Both print_mac() and sysfs_format_mac() call _format_mac_addr() to do the formatting. Changed print_mac() to use unsigned char * to be consistent with net_device struct's dev_addr. Added buffer length overrun checking as suggested by Joe Perches. Signed-off-by:

sk_forward_alloc being signed, we should take care of divides by SK_STREAM_MEM_QUANTUM we do in sk_stream_pages() and __sk_stream_mem_reclaim() This patchs introduces SK_STREAM_MEM_QUANTUM_SHIFT, defined as ilog2(SK_STREAM_MEM_QUANTUM), to be able to use right shifts instead of plain divides. This should help compiler to choose right shifts instead of expensive divides (as seen with CONFIG_CC_OPTIMIZE_FOR_SIZE=y on x86) Signed-off-by:
