Updates from NetBSD (cgd): - seriously clean up makefiles. use libsa/libkern/libz as appropriate, and don't build the various sources into objs locally by specifying them directly in the Makefiles. - move the secondary bootstrap down (to 0x20004000), and add a HEAP_LIMIT so that we don't exhaust our bootstrap address space (when using the new, not yet checked in, memory allocator). - clean up installboot, deal with secondary bootstrap programs not on 'a' partition or 'a' partition not starting at 0. - add padding to structures in bbinfo.h for future expansion. Add a netbbinfo structure to allow netboot information to be hard-coded in network boot blocks, so that they can be made to work even on systems with firmware which doesn't support the new "ethernet address in boot device" convention. - move the sync() calls to the correct place in installboot.c - remove a kludge in disk.c which was breaking multiple opens/closes of the disk - allow netboot ethernet address to be hard-coded into binary so that machines with old firmware which doesn't pass it in the boot device can work. Assume that if the ethernet address isn't passed in, it uses the old (dain-bramaged) 'read' interface works on my 3000/300LX. - Add setnetbootinfo, a program to hard code an ethernet address into a network boot. - move an 'int debug;' into boot.c (it was the only diff between boot.c and netboot.c), and nuke netboot.c (using boot.c instead for net boot blocks). - add cd9660 file system ops to the file system ops table in filesystem.c - if a file name is given (i.e. BOOTED_FILE) is set, boot only that file, but if not then try to boot "bsd", "bsd.bak", "bsd.old", and "obsd" (in that order) until one is found or until the list of names is exhausted. - add support for reading gzipped kernels. - use strerror() to print errors, rather than just printing error numbers - if no disk label exists, fake one up - slightly relax the block size checks in bootxx.c; they were a bit to paranoid
For open/openat, if the flags parameter does not contain O_CREAT, the 3rd (variadic) mode_t parameter is irrelevant. Many developers in the past have passed mode_t (0, 044, 0644, or such), which might lead future people to copy this broken idiom, and perhaps even believe this parameter has some meaning or implication or application. Delete them all. This comes out of a conversation where tb@ noticed that a strange (but intentional) pledge behaviour is to always knock-out high-bits from mode_t on a number of system calls as a safety factor, and his bewilderment that this appeared to be happening against valid modes (at least visually), but no sorry, they are all irrelevant junk. They could all be 0xdeafbeef. ok millert
