While here, re-enable lint in those cases where lint was skipped due to
a bug in interpreting abstract types, which was fixed in cgram.y 1.469
from 2023-08-02.
1. For tools that use elftoolchain: always use elftoolchain's
elfdefinitions.h. Don't even think about looking at the host's
sys/exec_elf.h, which makes no sense and should never happen.
(ELF tools that don't use elftoolchain, like m68k-elf2coff,
continue to use nbincludes/sys/exec_elf.h. But no more nbincludes
hacks in elftoolchain.)
2. For kernel components (solaris, zfs, dtrace): always use
sys/exec_elf.h, even in Solaris components via sys/elf.h.
elfdefinitions.h is not wired up in the kernel build at all.
3. For most userland components that involve libelf: use
elfdefinitions.h via libelf header files (libelf.h, gelf.h).
libdtrace in particular requires _all_ R_* reloc type definitions,
but sys/exec_elf.h brings in only the _current machine's_ R_*
reloc type definitions. (While here: Use uintptr_t instead of
Elf_Addr for pointer-to-integer cast, since Elf_Addr is MD and
provided only by sys/exec_elf.h, not by elfdefinitions.h.)
And most userland components using libelf don't rely on any
properties of the current machine from sys/exec_elf.h, so they can
use libelf's elfdefinition.h.
Exceptions:
- dtrace drti.c relies on link.h -> link_elf.h -> sys/exec_elf.h,
but it also relies on sys/dtrace.h -> sys/elf.h ->
elfdefinitions.h like other userland components using sys/elf.h.
- kdump-ioctl.c uses sys/exec_elf.h directly and sys/dtrace.h ->
sys/elf.h -> elfdefinitions like other userland components using
sys/elf.h.
- t_ptrace_wait.c (via t_ptrace_core_wait.h) uses libelf to parse
core files, but relies on sys/exec_elf.h for struct
netbsd_elfcore_procinfo.
None of these exceptions needs all R_* reloc type definitions, so
as a workaround, we can just suppress libelf's elfdefinitions.h by
defining _SYS_ELFDEFINITIONS_H_ and use sys/exec_elf.h in these
exceptions.
And undo the whole BUILTIN_ELF_HEADERS mistake. This was:
- half bogus workarounds for missing build_install dependencies in
tools/Makefile, which are no longer missing now, and
- half futile attempt to use src/sys/sys/exec_elf.h via nbincludes in
tools involving libelf instead of libelf's elfdefinitions.h, which
collides.
Longer-term, we may wish to unify sys/exec_elf.h and libelf's
elfdefinitions.h, so we don't have to play these games.
But at least now the games are limited to three .c files (one of
which is generated by Makefile.ioctl-c), rather than haphazardly
applied tree-wide by monstrous kludges in widely used .h files with
broken hackarounds to get the tools build lurching to completion.
Redo the previous correctly, the test should be whether or not only the
bottom 32 bits are set, rather than whether any of bits 32..63 are set.
This makes no difference if u_long (or unsigned long long) is 64 bits,
it is the same test in that case, but if u_long were 128 bits there is
a notable difference (though for the particular issue observed in the PR,
it is likely to work either way).
Provide a single variable
CC_WNO_ADDRESS_OF_PACKED_MEMBER
with options for both clang and gcc, to replace
CLANG_NO_ADDR_OF_PACKED_MEMBER
CC_NO_ADDR_OF_PACKED_MEMBER
GCC_NO_ADDR_OF_PACKED_MEMBER
Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.
unfortunately, the i915 ioctls are no longer handled by kdump/ktruss
as the new one conflicts with base. this needs a clean build in these
dirs (and rescue). the radeon ioctls have been enabled instead.
Previously, lint was only activated for the libraries, but not for the
kernel or userland programs. Activate lint for the programs in /usr/bin
for now, more will follow later.
This only affects builds that set MKLINT=yes.
- This conversion significantly simplifies the code and moves NPF to
a binary serialisation format (replacing the XML-like format).
- Fix some memory/reference leaks and possibly use-after-free bugs.
- Bump NPF_VERSION as this change makes libnpf incompatible with the
previous versions. Also, different serialisation format means NPF
connection/config saving and loading is not compatible with the
previous versions either.
Thanks to christos@ for extra testing.
this changes the upstream vendor from OpenSolaris to FreeBSD,
and this version is based on FreeBSD svn r315983.
in addition to the 10 years of improvements from upstream,
this version also has these NetBSD-specific enhancements:
- dtrace FBT probes can now be placed in kernel modules.
- ZFS now supports mmap().
Option name from FreeBSD. While here, make it possible to use a
combination of -T -E and -R to display timestamps in several formats.
Idea also from FreeBSD.
Note that on 32-bit platforms it probably never worked anyway because
header size changed from v1 to v2 when time_t became 64 bit.
