syslogd: Fix 'OPT_locallog' check regression in 'syslogd_main'

2025-04-08T14:14:34+00:00

In the recent refactoring of 'syslogd_main', a regression was introduced in handling the manual bitwise OR of 'OPT_locallog' as follows: if (ENABLE_FEATURE_REMOTE_LOG && !(opts & OPT_remotelog)) // -R option_mask32 |= OPT_locallog; 'opts' represents the locally-scoped output of 'getopt32' and 'option_mask32' represents the globally-scoped state of the same. Consequently, the above performs a bitwise OR to include 'OPT_locallog' of the globally-scoped option state, which 'opts' will not reflect locally. Manipulating the global, rather than local, state is correct as 'timestamp_and_log_internal' will later need to check 'OPT_locallog'. However, when the aforementioned refactor occurred, the following regressing change was made: - if (!ENABLE_FEATURE_REMOTE_LOG || (option_mask32 & OPT_locallog)) { + if (!ENABLE_FEATURE_REMOTE_LOG || (opts & OPT_locallog)) { breaking the spatially- and temporally-removed check in 'timestamp_and_log_internal'.
