There is a macro, `fork()`, inside of the philosophers example that conflicts with the POSIX `fork()` function. Since it is customary to avoid using reserved names, adjust the sample so that the macro in question is called `philosopher_fork()`. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>

`fork()` is defined by POSIX and for creating a new child process. It is the preferred method of doing so on systems with virtual memory and the symbol should not be used outside of the context defined by the POSIX standard. https://pubs.opengroup.org/onlinepubs/9699919799/functions/fork.html Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
CONFIG_XOPEN_STREAMS does not follow the pattern of other XSI Option Groups, where the Option Group name is not the same as the feature test macro that indicates it is supported by the implementation. Deprecate CONFIG_XOPEN_STREAMS and rename it to CONFIG_XSI_STREAMS. For more information, please see https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/\ V1_chap02.html#tag_02_01_05_09 Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
Deprecate the CONFIG_XOPEN_STREAMS Kconfig option in favour of CONFIG_XSI_STREAMS, which matches the naming conventions of other XSI Kconfig options and the actual Option Group name in the specification. Please use CONFIG_XSI_STREAMS instead. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
This change mitigates some code sonar issues (from SonarQube). 1. explicit 'U' after 0xffffffff > A cast shall not remove any const or volatile qualification from the > type of a pointer or reference c:S859 2. check return value from call to pthread_barrierattr_getpshared() > Unused assignments should be removed c:S1854 Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
This mitigates a sonarqube warning "Value stored to 'cvalue' is never read" > Unused assignments should be removed c:S1854 https://sonarcloud.io/project/issues?pullRequest=97152&\ open=AZnAZi4C7BgzESPFIGwf&id=zephyrproject-rtos_zephyr Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
This change mitigates a sonarqube warning about uninitialized variables. "1st function call argument is an uninitialized value" > Variables should be initialized before use c:S836 https://sonarcloud.io/project/issues?pullRequest=97152&\ open=AZnAZi0m7BgzESPFIGwe&id=zephyrproject-rtos_zephyr Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
If C libraries provide conformant POSIX headers, then use the headers provided by the C library. Otherwise, C library maintainers may add `include/zephyr/posix` to their standard search path. This change removes the requirement to have `<zephyr/posix/...>` prefixing all standard POSIX includes in Zephyr. The main reason that it was required was due to conflicts between C library time.h, signal.h and the fact that Zephyr posix headers were being somewhat ad-hoc mixed with libc posix headers. Now, any (even partially) POSIX-conformant C libraries are expected to provide their own types, constants, and headers, and Zephyr's implementation uses those definitions. If any definitions are missing, we define them on a per-libc basis. This can also be done out-of-tree, which allows for implementors to take advantage of the `CONFIG_TC_PROVIDES_POSIX..` options. This is likely the last major commit required before we deprecate the `CONFIG_POSIX_API` Kconfig option in favour of POSIX subprofiling \o/ Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
Include standard headers for POSIX types and functions instead of making implicit declarations. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
Remove the duplicate Kconfig option `CONFIG_POSIX_SYSTEM_INTERFACES` in `lib/posix/Kconfig.profile` that shadows the option in `lib/posix/Kconfig`. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
This change deprecates the Kconfig option `CONFIG_POSIX_API`. It is slated for removal in Zephyr v4.5.0. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
Add release notes about the deprecation of CONFIG_POSIX_API. User should instead use one of the pre-defined POSIX subprofiles CONFIG_POSIX_AEP_CHOICE_BASE CONFIG_POSIX_AEP_CHOICE_PSE51 CONFIG_POSIX_AEP_CHOICE_PSE52 CONFIG_POSIX_AEP_CHOICE_PSE53 and libraries should depend on CONFIG_POSIX_SYSTEM_INTERFACES as well as other POSIX Option Groups, as needed. For more information, please see https://pubs.opengroup.org/onlinepubs/9799919799/xrat/V4_subprofiles.html Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
The specification requires that unistd.h (or a file that is included via unistd.h) declare version macros and symbolic constants. Feature test macros declarations are also removed from `lib/posix/options/CMakeLists.txt`. Closes zephyrproject-rtos#97949 Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
