2018-03-20perf annotate: Stop using a global config structArnaldo Carvalho de Melo
For the TUI, that is interactive, its interesting to have a configuration that one can go on changing and then when moving from one symbol annotation to another symbol, the options set while browsing the first symbol to be kept. But since we're trying to make this code reusable by a --stdio formatter, we better have a pointer in struct annotation and in the TUI case set it to the global, but use something else for other cases, such as --stdio2.

2018-03-20netfilter: nf_tables: permit second nat hook if colliding hook is going awayFlorian Westphal
Sergei Trofimovich reported that restoring an nft ruleset doesn't work anymore unless old rule content is flushed first. The problem stems from a recent change designed to prevent multiple nat hooks at the same hook point locations and nftables transaction model. A 'flush ruleset' won't take effect until the entire transaction has completed. So, if one has a nft.rules file that contains a 'flush ruleset', followed by a nat hook register request, then 'nft -f file' will work, but running 'nft -f file' again will fail with -EBUSY. Reason is that nftables will place the flush/removal requests in the transaction list, but it will not act on the removal until after all new rules are in place. The netfilter core will therefore get request to register a new nat hook before the old one is removed -- this now fails as the netfilter core can't know the existing hook is staged for removal. To fix this, we can search the transaction log when a hook collision is detected. The collision is okay if 1. there is a delete request pending for the nat hook that is already registered. 2. there is no second add request for a matching nat hook. This is required to only apply the exception once.

2018-03-20netfilter: nf_tables: meter: pick a set backend that supports updatesFlorian Westphal
in nftables, 'meter' can be used to instantiate a hash-table at run time: rule add filter forward iif "internal" meter hostacct { ip saddr counter} nft list meter ip filter hostacct table ip filter { meter hostacct { type ipv4_addr elements = { 192.168.0.1 : counter packets 8 bytes 2672, .. because elemets get added on the fly, the kernel must chose a set backend type that implements the ->update() function, otherwise rule insertion fails with EOPNOTSUPP. Therefore, skip set types that lack ->update, and also make sure we do not discard a (bad) candidate when we did yet find any candidate at all. This could happen when userspace prefers low memory footprint -- the set implementation currently checked might not be a fit at all. Make sure we pick it anyway (!bops). In case next candidate is a better fix, it will be chosen instead. But in case nothing else is found we at least have a non-ideal match rather than no match at all.

2018-03-20cpufreq: speedstep: Don't validate the frequency table twiceViresh Kumar
The cpufreq core is already validating the CPU frequency table after calling the ->init() callback of the cpufreq drivers and the drivers don't need to do the same anymore. Though they need to set the policy->freq_table field directly from the ->init() callback now. Stop validating the frequency table from speedstep driver.

Though they need to set the policy->freq_table field directly from the ->init() callback now. Stop validating the frequency table from sh-cpufreq driver. The driver though prints the min/max frequency values and the same is done from the ->ready() callback now to keep the behavior unchanged.
