* net: sock: allow eBPF programs to be attached to socketsAlexei Starovoitov2014-12-063-0/+8
| | | | | | | | | | | | | | | | | | | | introduce new setsockopt() command: setsockopt(sock, SOL_SOCKET, SO_ATTACH_BPF, &prog_fd, sizeof(prog_fd)) where prog_fd was received from syscall bpf(BPF_PROG_LOAD, attr, ...) and attr->prog_type == BPF_PROG_TYPE_SOCKET_FILTER setsockopt() calls bpf_prog_get() which increments refcnt of the program, so it doesn't get unloaded while socket is using the program. The same eBPF program can be attached to multiple sockets. User task exit automatically closes socket which calls sk_filter_uncharge() which decrements refcnt of eBPF program Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.

Basically, enhancements for xt_recent, skip zeroing of timer in conntrack, fix linking problem with recent redirect support for nf_tables, ipset updates and a couple of cleanups. More specifically, they are: 1) Rise maximum number per IP address to be remembered in xt_recent while retaining backward compatibility, from Florian Westphal. 2) Skip zeroing timer area in nf_conn objects, also from Florian. 3) Inspect IPv4 and IPv6 traffic from the bridge to allow filtering using using meta l4proto and transport layer header, from Alvaro Neira. 4) Fix linking problems in the new redirect support when CONFIG_IPV6=n and IP6_NF_IPTABLES=n. And ipset updates from Jozsef Kadlecsik: 5) Support updating element extensions when the set is full (fixes netfilter bugzilla id 880). 6) Fix set match with 32-bits userspace / 64-bits kernel. 7) Indicate explicitly when /0 networks are supported in ipset. 8) Simplify cidr handling for hash:*net* types. 9) Allocate the proper size of memory when /0 networks are supported. 10) Explicitly add padding elements to hash:net,net and hash:net,port, because the elements must be u32 sized for the used hash function. Jozsef is also cooking ipset RCU conversion which should land soon if they reach the merge window in time. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
| * netfilter: ipset: Alignment problem between 64bit kernel 32bit userspaceJozsef Kadlecsik2014-12-032-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sven-Haegar Koch reported the issue: sims:~# iptables -A OUTPUT -m set --match-set testset src -j ACCEPT iptables: Invalid argument. Run `dmesg' for more information. In syslog: x_tables: ip_tables: set.3 match: invalid size 48 (kernel) != (user) 32 which was introduced by the counter extension in ipset. The patch fixes the alignment issue with introducing a new set match revision with the fixed underlying 'struct ip_set_counter_match' structure.

* | bridge: add API to notify bridge driver of learned FBD on offloaded deviceScott Feldman2014-12-032-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the swdev device learns a new mac/vlan on a port, it sends some async notification to the driver and the driver installs an FDB in the device. To give a holistic system view, the learned mac/vlan should be reflected in the bridge's FBD table, so the user, using normal iproute2 cmds, can view what is currently learned by the device. This API on the bridge driver gives a way for the swdev driver to install an FBD entry in the bridge FBD table. (And remove one). This is equivalent to the device running these cmds: bridge fdb [add|del] <mac> dev <dev> vid <vlan id> master This patch needs some extra eyeballs for review, in paricular around the locking and contexts.

Most of these are fairly standard little fixes, a bmc150 and bmg160 patch is to make an ABI change to indicated a specific axis in an event rather than the generic option in the original drivers. As both of these drivers are new in this cycle it would be ideal to push this minor change through even though it isn't strictly a fix. A couple of other 'fixes' change defaults for some settings on these new drivers to more intuitive calues. Looks like some useful feedback has been coming in for this driver since it was applied. * IIO_EVENT_CODE_EXTRACT_DIR bit mask was wrong and has been for a while 0xCF clearly doesn't give a contiguous bitmask. * kxcjk-1013 range setting was failing to mask out the previous value in the register and hence was 'enable only'. * men_z188 device id table wasn't null terminated. * bmg160 and bmc150 both failed to correctly handling an error in mode setting. * bmg160 and bmc150 both had a bug in setting the event direction in the event spec (leads to an attribute name being incorrect) * bmg160 defaulted to an open drain output for the interrupt - as a default this obviously only works with some interrupt chips - hence change the default to push-pull (note this is a new driver so we aren't going to cause any regressions with this change). * bmc150 had an unintuitive default for the rate of change (motion detector) so change it to 0 (new driver so change of default won't cause any regressions).

The problem being addressed by the patch above was that some ARM code based the memory mapping attributes of a pfn on the return value of kvm_is_mmio_pfn(), whose name indeed suggests that such pfns should be mapped as device memory. However, kvm_is_mmio_pfn() doesn't do quite what it says on the tin, and the existing non-ARM users were already using it in a way which suggests that its name should probably have been 'kvm_is_reserved_pfn' from the beginning, e.g., whether or not to call get_page/put_page on it etc. This means that returning false for the zero page is a mistake and the patch above should be reverted.

So we made the quirk generic and fixed both the graphic and audio drivers properly to use it. Without that, ppc64 server machines will crash at boot with a radeon adapter.

However using this flag has the unfortunate side effect of causing the clock recalculation code when a clock rate change is attempted to always treat it as a pass-through clock, i.e. with a fixed divide of 1, which may not be the case. Child clock rates are then recalculated using the wrong parent rate. Therefore instead of dropping the recalc_rate() and round_rate() callbacks, alter clk_divider_bestdiv() to always report the current divider as the best divider so that it is never altered. For me the read only clock was the system clock, which divided the PLL rate by 2, from which both the UART and the SPI clocks were divided. Initial setting of the UART rate set it correctly, but when the SPI clock was set, the other child clocks were miscalculated. The UART clock was recalculated using the PLL rate as the parent rate, resulting in a UART new_rate of double what it should be, and a UART which spewed forth garbage when the rate changes were propagated.

Because __ref_is_percpu() returns @ref->percpu_count_ptr value verbatim as the percpu pointer after testing ATOMIC, the pointer may now be contaminated with the DEAD flag. This can be fixed by clearing the flag bits before returning the pointer which was the fix proposed by Shaohua; however, as DEAD implies ATOMIC, we can just test for both flags at once and avoid the explicit masking. Update __ref_is_percpu() so that it tests that both ATOMIC and DEAD are clear before returning @ref->percpu_count_ptr as the percpu pointer.

Patch from Alex Gartrell. 4) Add nft_log_dereference() macro to the nf_log infrastructure, patch from Marcelo Leitner. 5) Add some extra validation when registering logger families, also from Marcelo. 6) Some spelling cleanups from stephen hemminger. 7) Fix sparse warning in nf_logger_find_get(). 8) Add cgroup support to nf_tables meta, patch from Ana Rey. 9) A Kconfig fix for the new redir expression and fix sparse warnings in the new redir expression. 10) Fix several sparse warnings in the netfilter tree, from Florian Westphal. 11) Reduce verbosity when OOM in nfnetlink_log. User can basically do nothing when this situation occurs. 12) Add conntrack zone support to xt_connlimit, again from Florian. 13) Add netnamespace support to the h323 conntrack helper, contributed by Vasily Averin. 14) Remove unnecessary nul-pointer checks before free_percpu() and module_put(), from Markus Elfring. 15) Use pr_fmt in nfnetlink_log, again patch from Marcelo Leitner. ==================== Signed-off-by: David S.
