head -r320482 vs. TARGET_ARCH=powerpc production style kernel: jumps to non-code and traps (but the debug kernel build works for the same world)

2017-06-30 Thread Mark Millard
The -r320482 kernel build is via gcc 4.2.1. Both gcc 4.2.1 and clang based worlds show the same problems. TARGET_ARCH=powerpc64 is not showing the problems. The production kernel build fails but the debug works --each built from the same /usr/src/ tree. I'll note what a normal boot does before ge

hi! there is an question about the tty line (canonical) mode — the internal implementation is using 2k buffer, but the related (public) constants are claiming buffer size about 255 chars. Why it is so - any hints about the background there? #define MAX_CANON 255 /* max bytes

Hi, This commit https://svnweb.freebsd.org/base?view=revision&revision=r320472 breaks column(1) (and can affect something else this way ). Try to execute sample from man r320472: ( printf "PERM LINKS OWNER GROUP SIZE MONTH DAY " ; printf "HH:MM/YEAR NAME\n" ; ls -l | sed 1d ) | column -t colu

[It looks like the 2 anonymous structs in the union in the new "struct socket" are being abused such that the ->sol_upcall from the 2nd struct is being access when it has a value that was apparently assigned via ->so_rcv->sb_sel . Details follow, added to prior notes that I sent out. I've submitte
