2021-08-09netfilter: x_tables: never register tables by defaultFlorian Westphal1-13/+11
For historical reasons x_tables still register tables by default in the initial namespace. Only newly created net namespaces add the hook on demand. This means that the init_net always pays hook cost, even if no filtering rules are added (e.g. only used inside a single netns). Note that the hooks are added even when 'iptables -L' is called. This is because there is no way to tell 'iptables -A' and 'iptables -L' apart at kernel level. The only solution would be to register the table, but delay hook registration until the first rule gets added (or policy gets changed). That however means that counters are not hooked either, so 'iptables -L' would always show 0-counters even when traffic is flowing which might be unexpected. This keeps table and hook registration consistent with what is already done in non-init netns: first iptables(-save) invocation registers both table and hooks. This applies the same solution adopted for ebtables. All tables register a template that contains the l3 family, the name and a constructor function that is called when the initial table has to be added.

2021-04-26netfilter: x_tables: remove paranoia testsFlorian Westphal1-3/+0
No need for these. There is only one caller, the xtables core, when the table is registered for the first time with a particular network namespace. After ->table_init() call, the table is linked into the tables[af] list, so next call to that function will skip the ->table_init().

2018-01-16netfilter: nf_defrag: mark xt_table structures 'const' againArnd Bergmann1-5/+19
As a side-effect of adding the module option, we now get a section mismatch warning: WARNING: net/ipv4/netfilter/iptable_raw.o(.data+0x1c): Section mismatch in reference from the variable packet_raw to the function .init.text:iptable_raw_table_init() The variable packet_raw references the function __init iptable_raw_table_init() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console Apparently it's ok to link to a __net_init function from .rodata but not from .data. We can address this by rearranging the logic so that the structure is read-only again. Instead of writing to the .priority field later, we have an extra copies of the structure with that flag. An added advantage is that that we don't have writable function pointers with this approach.

2018-01-11netfilter: nf_defrag: Skip defrag if NOTRACK is setSubash Abhinov Kasiviswanathan1-1/+12
conntrack defrag is needed only if some module like CONNTRACK or NAT explicitly requests it. For plain forwarding scenarios, defrag is not needed and can be skipped if NOTRACK is set in a rule. Since conntrack defrag is currently higher priority than raw table, setting NOTRACK is not sufficient. We need to move raw to a higher priority for iptables only. This is achieved by introducing a module parameter "raw_before_defrag" which allows to change the priority of raw table to place it before defrag. By default, the parameter is disabled and the priority of raw table is NF_IP_PRI_RAW to support legacy behavior. If the module parameter is enabled, then the priority of the raw table is set to NF_IP_PRI_RAW_BEFORE_DEFRAG.

2016-03-02netfilter: xtables: don't hook tables by defaultFlorian Westphal1-14/+23
delay hook registration until the table is being requested inside a namespace. Historically, a particular table (iptables mangle, ip6tables filter, etc) was registered on module load. When netns support was added to iptables only the ip/ip6tables ruleset was made namespace aware, not the actual hook points. This means f.e. that when ipt_filter table/module is loaded on a system, then each namespace on that system has an (empty) iptables filter ruleset. In other words, if a namespace sends a packet, such skb is 'caught' by netfilter machinery and fed to hooking points for that table (i.e. INPUT, FORWARD, etc). Thanks to Eric Biederman, hooks are no longer global, but per namespace. This means that we can avoid allocation of empty ruleset in a namespace and defer hook registration until we need the functionality. We register a tables hook entry points ONLY in the initial namespace. When an iptables get/setockopt is issued inside a given namespace, we check if the table is found in the per-namespace list. If not, we attempt to find it in the initial namespace, and, if found, create an empty default table in the requesting namespace and register the needed hooks. Hook points are destroyed only once namespace is deleted, there is no 'usage count' (it makes no sense since there is no 'remove table' operation in xtables api).

2016-03-02netfilter: xtables: prepare for on-demand hook registerFlorian Westphal1-4/+5
This change prepares for upcoming on-demand xtables hook registration. We change the protoypes of the register/unregister functions. A followup patch will then add nf_hook_register/unregister calls to the iptables one. Once a hook is registered packets will be picked up, so all assignments of the form net->ipv4.iptable_$table = new_table have to be moved to ip(6)t_register_table, else we can see NULL net->ipv4.iptable_$table later. This patch doesn't change functionality; without this the actual change simply gets too big. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.hTejun Heo1-0/+1
percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

The order of the IPv6 raw table is currently reversed, that makes impossible to use the NOTRACK target in IPv6: for example if someone enters ip6tables -t raw -A PREROUTING -p tcp --dport 80 -j NOTRACK and if we receive fragmented packets then the first fragment will be untracked and thus skip nf_ct_frag6_gather (and conntrack), while all subsequent fragments enter nf_ct_frag6_gather and reassembly will never successfully be finished.

Typical table module registers xt_table structure (i.e. packet_filter) and link it to list during it. We can't use one template for it because corresponding list_head will become corrupted. We also can't unregister with template because it wasn't changed at all and thus doesn't know in which list it is. So, we duplicate template at the very first step of table registration. Table modules will save it for use during unregistration time and actual filtering. Do it at once to not screw bisection.
