2022-02-21unveil(2) "/dev" read-only instead of using chroot(2)/chdir(2). after callingRicardo Mestre
the latter the program then also calls stat(2) and therefore it never actually worked correctly since they were added almost 20 years now. while here remove an implementation detail from the manpage which covered the chroot part. pointed out by and ok deraadt@
2022-01-31Nothing depends on archdep.h pulling in other #includes anymore,Philip Guenther
so delete the #includes and hide the RELOC_* functions that are only used by lib/csu behind "#ifdef RCRT0" matches the others and it's hard to see how it will fail
2022-01-31Inline RELOC_* into boot_md.c and simplify the code based on whatPhilip Guenther
we can verify at build time. Track dt_pltgot as an Elf_Addr instead of an Elf_Addr* to eliminat casts on both setting and using. Set RELATIVE_RELOC so the ld.so Makefile can verify that it has just the relocation types we expect. Nothing depends on archdep.h pulling in other #includes anymore, so delete the #includes and hide the RELOC_* functions that are only used by lib/csu behind "#ifdef RCRT0" Tested with full build.

2022-01-17Stop supporting a GOT with only one reserved entry in static PIEPhilip Guenther
and ld.so itself: support for that in dynamic objects was removed in 2010. Inline RELOC_GOT() into boot_md.c and clean up the result like boot.c, snag just the three DT_MIPS_* tags needed, and delete the error case which is verified at build time. ok visa@

2021-12-23Roll the syscalls that have an off_t argument to remove the explicit padding.Philip Guenther
Switch libc and ld.so to the generic stubs for these calls. WARNING: reboot to updated kernel before installing libc or ld.so! Time for a story... When gcc (back in 1.x days) first implemented long long, it didn't (always) pass 64bit arguments in 'aligned' registers/stack slots, with the result that argument offsets didn't match structure offsets. This affected the nine system calls that pass off_t arguments: ftruncate lseek mmap mquery pread preadv pwrite pwritev truncate To avoid having to do custom ASM wrappers for those, BSD put an explicit pad argument in so that the off_t argument would always start on a even slot and thus be naturally aligned. Thus those odd wrappers in lib/libc/sys/ that use __syscall() and pass an extra '0' argument. The ABIs for different CPUs eventually settled how things should be passed on each and gcc 2.x followed them. The only arch now where it helps is landisk, which needs to skip the last argument register if it would be the first half of a 64bit argument. So: add new syscalls without the pad argument and on landisk do that skipping directly in the syscall handler in the kernel. Keep compat support for the existing syscalls long enough for the transition. ok deraadt@

Annotate RELOC_DYN() on non-hppa as only used in lib/csu. Delete some inconsistent comments, adjust whitespace, and reorder mips64's archdep.h so that the ld.so/*/archdep.h files look (almost) the same. ok visa@ kettenis@

2021-10-24For open/openat, if the flags parameter does not contain O_CREAT, theTheo de Raadt
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
