* msun tests: use standard floating-point exception flags on lrint and fenv testsAlfredo Dal'Ava Junior2020-11-182-9/+12
| | | | | | | | | | | | | | | Some platforms have additional architecture-specific floating-point flags. Msun test cases lrint and test_fegsetenv (fenv) expects only standard flags, so make sure to mask them appropriately. This makes test pass on PowerPC64.

* _umtx_op: fix a compat32 bug in UMTX_OP_NWAKE_PRIVATEKyle Evans2020-11-172-0/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Specifically, if we're waking up some value n > BATCH_SIZE, then the copyin(9) is wrong on the second iteration due to upp being the wrong type. upp is currently a uint32_t**, so upp + pos advances it by twice as many elements as it should (host pointer size vs. compat32 pointer size). Fix it by just making upp a uint32_t*; it's still technically a double pointer, but the distinction doesn't matter all that much here since we're just doing arithmetic on it. Add a test case that demonstrates the problem, placed with the libthr tests since one messing with _umtx_op should be running these tests. Running under compat32, the new test case will hang as threads after the first 128 get missed in the wake. it's not immediately clear how to hit it in practice, since pthread_cond_broadcast() uses a smaller (sleepq batch?) size observed to be around ~50 -- I did not spend much time digging into it. The uintptr_t change makes no functional difference, but i've tossed it in since it's more accurate (semantically).

* Add collation version support to querylocale(3).Thomas Munro2020-11-085-16/+57
| | | | | | | | | | | | | | | | | | | | | | | Provide a way to ask for an opaque version string for a locale_t, so that potential changes in sort order can be detected. Similar to ICU's ucol_getVersion() and Windows' GetNLSVersionEx(), this API is intended to allow databases to detect when text order-based indexes might need to be rebuilt. The CLDR version is extracted from CLDR source data by the Makefile under tools/tools/locale, written into the machine-generated Makefile under shared/colldef, passed to localedef -V, and then written into LC_COLLATE file headers. The initial version is 34.0. tools/tools/locale was recently updated to pull down 35.0, but the output hasn't been committed under share/colldef yet, so that will provide the first observable change when it happens. Other versioning schemes are possible in future, because the format is unspecified.

* Make sysctl user.local a tunable that can be written at run-timeStefan Eßer2020-10-311-10/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | This sysctl value had been provided as a read-only variable that is compiled into the C library based on the value of _PATH_LOCALBASE in paths.h. After this change, the value is compiled into the kernel as an empty string, which is translated to _PATH_LOCALBASE by the C library. This empty string can be overridden at boot time or by a privileged user at run time and will then be returned by sysctl. When set to an empty string, the value returned by sysctl reverts to _PATH_LOCALBASE. This update does not change the behavior on any system that does not modify the default value of user.localbase. I consider this change as experimental and would prefer if the run-time write permission was reconsidered and the sysctl variable defined with CLFLAG_RDTUN instead to restrict it to be set at boot time.

* Replace literal uses of /usr/local in C sources with _PATH_LOCALBASEStefan Eßer2020-10-272-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Literal references to /usr/local exist in a large number of files in the FreeBSD base system. Many are in contributed software, in configuration files, or in the documentation, but 19 uses have been identified in C source files or headers outside the contrib and sys/contrib directories. This commit makes it possible to set _PATH_LOCALBASE in paths.h to use a different prefix for locally installed software. In order to avoid changes to openssh source files, LOCALBASE is passed to the build via Makefiles under src/secure. While _PATH_LOCALBASE could have been used here, there is precedent in the construction of the path used to a xauth program which depends on the LOCALBASE value passed on the compiler command line to select a non-default directory. This could be changed in a later commit to make the openssh build consistently use _PATH_LOCALBASE. It is considered out-of-scope for this commit.
