2020-02-07sunrpc: expiry_time should be seconds not timevalRoberto Bergantinos Corpas1-0/+4
When upcalling gssproxy, cache_head.expiry_time is set as a timeval, not seconds since boot. As such, RPC cache expiry logic will not clean expired objects created under auth.rpcsec.context cache. This has proven to cause kernel memory leaks on field. Using 64 bit variants of getboottime/timespec Expiration times have worked this way since 2010's c5b29f885afe "sunrpc: use seconds since boot in expiry cache". The gssproxy code introduced in 2012 added gss_proxy_save_rsc and introduced the bug. That's a while for this to lurk, but it required a bit of an extreme case to make it obvious.

Don't do a single array; attach them to fsparam_enum() entry instead. And don't bother trying to embed the names into those - it actually loses memory, with no real speedup worth mentioning. Simplifies validation as well. Signed-off-by: Al Viro <[email protected]>
2020-02-07Pass consistent param->type to fs_parse()Al Viro4-20/+16
As it is, vfs_parse_fs_string() makes "foo" and "foo=" indistinguishable; both get fs_value_is_string for ->type and NULL for ->string. To make it even more unpleasant, that combination is impossible to produce with fsconfig(). Much saner rules would be "foo" => fs_value_is_flag, NULL "foo=" => fs_value_is_string, "" "foo=bar" => fs_value_is_string, "bar" All cases are distinguishable, all results are expressable by fsconfig(), ->has_value checks are much simpler that way (to the point of the field being useless) and quite a few regressions go away (gfs2 has no business accepting -o nodebug=, for example). Partially based upon patches from Miklos. Signed-off-by: Al Viro <[email protected]>

2020-02-06drm/tegra: Reuse IOVA mapping where possibleThierry Reding3-23/+63
This partially reverts the DMA API support that was recently merged because it was causing performance regressions on older Tegra devices. Unfortunately, the cache maintenance performed by dma_map_sg() and dma_unmap_sg() causes performance to drop by a factor of 10. The right solution for this would be to cache mappings for buffers per consumer device, but that's a bit involved. Instead, we simply revert to the old behaviour of sharing IOVA mappings when we know that devices can do so (i.e. they share the same IOMMU domain).

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - Added new "bootconfig". This looks for a file appended to initrd to add boot config options, and has been discussed thoroughly at Linux Plumbers. Very useful for adding kprobes at bootup. Only enabled if "bootconfig" is on the real kernel command line. - Created dynamic event creation. Merges common code between creating synthetic events and kprobe events. - Rename perf "ring_buffer" structure to "perf_buffer" - Rename ftrace "ring_buffer" structure to "trace_buffer" Had to rename existing "trace_buffer" to "array_buffer" - Allow trace_printk() to work withing (some) tracing code. - Sort of tracing configs to be a little better organized - Fixed bug where ftrace_graph hash was not being protected properly - Various other small fixes and clean ups * tag 'trace-v5.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (88 commits) bootconfig: Show the number of nodes on boot message tools/bootconfig: Show the number of bootconfig nodes bootconfig: Add more parse error messages bootconfig: Use bootconfig instead of boot config ftrace: Protect ftrace_graph_hash with ftrace_sync ftrace: Add comment to why rcu_dereference_sched() is open coded tracing: Annotate ftrace_graph_notrace_hash pointer with __rcu tracing: Annotate ftrace_graph_hash pointer with __rcu bootconfig: Only load bootconfig if "bootconfig" is on the kernel cmdline tracing: Use seq_buf for building dynevent_cmd string tracing: Remove useless code in dynevent_arg_pair_add() tracing: Remove check_arg() callbacks from dynevent args tracing: Consolidate some synth_event_trace code tracing: Fix now invalid var_ref_vals assumption in trace action tracing: Change trace_boot to use synth_event interface tracing: Move tracing selftests to bottom of menu tracing: Move mmio tracer config up with the other tracers tracing: Move tracing test module configs together tracing: Move all function tracing configs together tracing: Documentation for in-kernel synthetic event API ...

Show the number of bootconfig nodes when applying new bootconfig to initrd. Since there are limitations of bootconfig not only in its filesize, but also the number of nodes, the number should be shown when applying so that user can get the feeling of scale of current bootconfig.
