[patch 1/6] ipset: turn Set name[] into a const pointer

[Holger Eitzenberger]

[-- Attachment #1: ipset-set_type-name-pointer.diff --]
[-- Type: text/plain, Size: 2005 bytes --]

Also check for the name length.

Note that passing errno values back is not done consistently at
various place, as there are some functions which set errno manually,
others pass -errno back.  I use the -errno approach here, as it is
slightly shorter.

[patch 2/6] ipset: fix the Netlink sequence number

[Holger Eitzenberger]

[-- Attachment #1: ipset-netlink-sequence.diff --]
[-- Type: text/plain, Size: 999 bytes --]

Do not use time() as a Netlink sequence number for each message,
as otherwise the same seq number will be used when sending
another message in the same second.  Instead use time() just for
initialization, then increment per message.

We can't do this, because then the flag-style options (no arg) cannot be 
parsed. So I cannot apply this patch and the next two ones based on it.

If optstr is kept, then that can be passed to the parser in the default 
branch. Could you rewrite your patch that way and resend to me (and the 
dependent ones too)?

[patch 4/6] ipset: avoid the unnecessary argv[] loop

[Holger Eitzenberger]

[-- Attachment #1: ipset-remove-unnecessary-argv-loop.diff --]
[-- Type: text/plain, Size: 3397 bytes --]

After stripping off the global options there simply has to follow
a command name, there is no other syntax possible.  Therefore the
argv[] loop is unnecessary.

The number of comparisons for a matching a command name can be
made smaller by just checking on argv[1].

As an example consider the following 'create' arguments 'hashsize',
'family' and 'timeout'.  When having the command
 
 create foo hash:ip timeout 60 family inet hashsize 64

it compares without this patch:

 strcmp("timeout", "hashsize")
 strcmp("64", "hashsize")
 strcmp("family", "hashsize")
 strcmp("inet", "hashsize")
 strcmp("hashsize", "hashsize")

It is worse in practice, as 'create' has more arguments than this.
