| | | | | | | | | | | | | | | | | | | | | | Using set remotebaud to set the baud rate was deprecated in gdb-7.7 and completely removed from the command parser in gdb-7.8 (released in 2014). Adopt set serial baud instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most readers are probably going to figure out that the config is actually all upper-case letters, as all Kconfig symbols are this way. Properly capitalizing makes the script ./scripts/checkkconfigsymbols.py happy, which otherwise would report this as a reference to a non-existing Kconfig symbol. So, use the right capitalization for the MAGIC_SYSRQ config in the kgdb documentation.

* | kunit: tool: reconfigure when the used kunitconfig changesDaniel Latypov2021-12-131-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: currently, if you remove something from your kunitconfig, kunit.py will not regenerate the .config file. The same thing happens if you did --kunitconfig_add=CONFIG_KASAN=y [1] and then ran again without it. Your new run will still have KASAN. The reason is that kunit.py won't regenerate the .config file if it's a superset of the kunitconfig. This speeds it up a bit for iterating. This patch adds an additional check that forces kunit.py to regenerate the .config file if the current kunitconfig doesn't match the previous one. What this means: * deleting entries from .kunitconfig works as one would expect * dropping a --kunitconfig_add also triggers a rebuild * you can still edit .config directly to turn on new options We implement this by creating a `last_used_kunitconfig` file in the build directory (so .kunit, by default) after we generate the .config. When comparing the kconfigs, we compare python sets, so duplicates and permutations don't trip us up. The majority of this patch is adding unit tests for the existing logic and for the new case where `last_used_kunitconfig` differs.

| * kfence: default to dynamic branch instead of static keys modeMarco Elver2021-11-061-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have observed that on very large machines with newer CPUs, the static key/branch switching delay is on the order of milliseconds. This is due to the required broadcast IPIs, which simply does not scale well to hundreds of CPUs (cores). If done too frequently, this can adversely affect tail latencies of various workloads. One workaround is to increase the sample interval to several seconds, while decreasing sampled allocation coverage, but the problem still exists and could still increase tail latencies. As already noted in the Kconfig help text, there are trade-offs: at lower sample intervals the dynamic branch results in better performance; however, at very large sample intervals, the static keys mode can result in better performance -- careful benchmarking is recommended. Our initial benchmarking showed that with large enough sample intervals and workloads stressing the allocator, the static keys mode was slightly better. Evaluating and observing the possible system-wide side-effects of the static-key-switching induced broadcast IPIs, however, was a blind spot (in particular on large machines with 100s of cores). Therefore, a major downside of the static keys mode is, unfortunately, that it is hard to predict performance on new system architectures and topologies, but also making conclusions about performance of new workloads based on a limited set of benchmarks. Most distributions will simply select the defaults, while targeting a large variety of different workloads and system architectures. As such, the better default is CONFIG_KFENCE_STATIC_KEYS=n, and re-enabling it is only recommended after careful evaluation. For reference, on x86-64 the condition in kfence_alloc() generates exactly 2 instructions in the kmem_cache_alloc() fast-path: | ... | cmpl $0x0,0x1a8021c(%rip) # ffffffff82d560d0 <kfence_allocation_gate> | je ffffffff812d6003 <kmem_cache_alloc+0x243> | ... which, given kfence_allocation_gate is infrequently modified, should be well predicted by most CPUs.

|/ | | | | | | | | | | | | | | | | | | | | | Architectures supported by KASAN_HW_TAGS can provide an asymmetric mode of execution. On an MTE enabled arm64 hw for example this can be identified with the asymmetric tagging mode of execution. In particular, when such a mode is present, the CPU triggers a fault on a tag mismatch during a load operation and asynchronously updates a register when a tag mismatch is detected during a store operation. Extend the KASAN HW execution mode kernel command line parameter to support asymmetric mode.

The option CONFIG_KCSAN_PERMISSIVE is disabled by default, so that the documented default behaviour of KCSAN does not change.

Drop the small kunit_parser.raw_output() function since it feels wrong to put it in "kunit_parser.py" when the point of it is to not parse anything.

The need to use older versions of GCC (<=6) remains however, due to linktime issues, same as before. Note: There also might still be issues with .gcda files as well in newer versions.
