* config.5: Document CONF_CFLAGS under 'makeoptions'Olivier Certner2025-06-131-0/+17
| | | | | | | | | | | | | | | | This variable serves to tweak CFLAGS from the kernel configuration file, easing some custom kernel builds. It was introduced by bde@ in 1999. The description has been kept simple on purpose. It does not completely reflect reality as the build infrastructure actually appends variables to CFLAGS after CONF_CFLAGS has been processed in a few cases. However, these cases do not collide with expected common uses of CONF_CFLAGS, so have not been mentioned.

* packages: rename elftoolchain to toolchain, add more thingsLexi Winter2025-05-281-0/+1
| | | | | | | | | | | | | | Rename the existing "elftoolchain" package to "toolchain", and move everything which is gated by MK_TOOLCHAIN (e.g. lex, yacc, ...) to the toolchain package. This means we have one package called "toolchain" which contains all the development-related utilities which are not compilers or already part of some other package (e.g., llvm).

| | | | | | | | | | | | | Use an std::stringstream instead. get_word() and get_quoted_word() both return a buffer that's presumed to not need release, so solve this by returning a new special configword type that holds a string or eof/eol state.

| | | | | | | | | | | | | | | | | Recently added/changed lines in various kernel configs have caused some buffer overflows that went undetected. These were detected with a config built using -fno-common as these line buffers smashed one of our arrays, then further triaged with ASAN. Double the sizes; this is really not a great fix, but addresses the immediate need until someone rewrites config.
