Some code here depends on CONFIG_KMOD to not try to load protocol modules or similar, replace by CONFIG_MODULES where more than just request_module depends on CONFIG_KMOD and and also use try_then_request_module in ebtables.

2008-10-16driver core: basic infrastructure for per-module dynamic debug messagesJason Baron
Base infrastructure to enable per-module debug messages. I've introduced CONFIG_DYNAMIC_PRINTK_DEBUG, which when enabled centralizes control of debugging statements on a per-module basis in one /proc file, currently, <debugfs>/dynamic_printk/modules. When, CONFIG_DYNAMIC_PRINTK_DEBUG, is not set, debugging statements can still be enabled as before, often by defining 'DEBUG' for the proper compilation unit. Thus, this patch set has no affect when CONFIG_DYNAMIC_PRINTK_DEBUG is not set. The infrastructure currently ties into all pr_debug() and dev_dbg() calls. That is, if CONFIG_DYNAMIC_PRINTK_DEBUG is set, all pr_debug() and dev_dbg() calls can be dynamically enabled/disabled on a per-module basis. Future plans include extending this functionality to subsystems, that define their own debug levels and flags. Usage: Dynamic debugging is controlled by the debugfs file, <debugfs>/dynamic_printk/modules. This file contains a list of the modules that can be enabled. The format of the file is as follows: <module_name> <enabled=0/1> . . . <module_name> : Name of the module in which the debug call resides <enabled=0/1> : whether the messages are enabled or not For example: snd_hda_intel enabled=0 fixup enabled=1 driver enabled=0 Enable a module: $echo "set enabled=1 <module_name>" > dynamic_printk/modules Disable a module: $echo "set enabled=0 <module_name>" > dynamic_printk/modules Enable all modules: $echo "set enabled=1 all" > dynamic_printk/modules Disable all modules: $echo "set enabled=0 all" > dynamic_printk/modules Finally, passing "dynamic_printk" at the command line enables debugging for all modules. This mode can be turned off via the above disable command.

2008-10-14netfilter: ctnetlink: remove bogus module dependency between ctnetlink and ↵Pablo Neira Ayuso
nf_nat This patch removes the module dependency between ctnetlink and nf_nat by means of an indirect call that is initialized when nf_nat is loaded. Now, nf_conntrack_netlink only requires nf_conntrack and nfnetlink. This patch puts nfnetlink_parse_nat_setup_hook into the nf_conntrack_core to avoid dependencies between ctnetlink, nf_conntrack_ipv4 and nf_conntrack_ipv6. This patch also introduces the function ctnetlink_change_nat that is only invoked from the creation path. Actually, the nat handling cannot be invoked from the update path since this is not allowed. By introducing this function, we remove the useless nat handling in the update path and we avoid deadlock-prone code. This patch also adds the required EAGAIN logic for nfnetlink.

2008-10-11ipvs: Add proper dependencies on IP_VS, and fix description header line.David S. Miller
Linus noted a build failure case: net/netfilter/ipvs/ip_vs_xmit.c: In function 'ip_vs_tunnel_xmit': net/netfilter/ipvs/ip_vs_xmit.c:616: error: implicit declaration of function 'ip_select_ident' The proper include file (net/ip.h) is being included in ip_vs_xmit.c to get that declaration. So the only possible case where this can happen is if CONFIG_INET is not enabled. This seems to be purely a missing dependency in the ipvs/Kconfig file IP_VS entry. Also, while we're here, remove the out of date "EXPERIMENTAL" string in the IP_VS config help header line. IP_VS no longer depends upon CONFIG_EXPERIMENTAL Signed-off-by: David S.

2008-10-08netfilter: xtables: move extension arguments into compound structure (1/6)Jan Engelhardt
The function signatures for Xtables extensions have grown over time. It involves a lot of typing/replication, and also a bit of stack space even if they are not used. Realize an NFWS2008 idea and pack them into structs. The skb remains outside of the struct so gcc can continue to apply its optimizations. This patch does this for match extensions' match functions. A few ambiguities have also been addressed. The "offset" parameter for example has been renamed to "fragoff" (there are so many different offsets already) and "protoff" to "thoff" (there is more than just one protocol here, so clarify).
