Remove temporary macros created for transition from long
to kernel_ulong_t.
Automatically replace PRI_kr[dux] with PRI_kl[dux] using
$ git grep -l 'PRI_kr[dux]' | xargs sed -ri 's/PRI_kr([dux])/PRI_kl\1/g'
* defs.h (PRI_krd, PRI_kru, PRI_krx): Remove. All users updated.
Remove temporary types created for transition from long
to kernel_ulong_t.
Automatically replace kernel_scno_t and kernel_ureg_t with
kernel_ulong_t using
$ git grep -El 'kernel_(scno|ureg)_t' |
xargs sed -ri 's/kernel_(scno|ureg)_t/kernel_ulong_t/g'
* kernel_types.h (kernel_scno_t, kernel_ureg_t): Remove.
All users updated.
Prepare for the change of kernel_ureg_t and kernel_scno_t from
unsigned long to kernel_ulong_t.
* defs.h (PRI_krd, PRI_kru, PRI_krx): New temporary macros.
All users updated.
* kexec.c (SYS_FUNC(kexec_load)): Change n variable type
from unsigned long to kernel_ureg_t. Use printxval64 instead
of printxval_long. Use printflags64 instead of printflags_long.
* kexec.c (print_seg): Change the type of *seg and seg_buf variables
from unsigned long to kernel_ureg_t.
(print_kexec_segments): Change len argument type from unsigned long
to kernel_ureg_t. Change seg variable type from unsigned long
to kernel_ureg_t.
As about half of all printstr uses cases are invocations with the last
argument set to -1, create a dedicated function for this use case.
* defs.h (printstr): Rename to printstrn. All callers updated.
(printstr): New static inline function. All callers updated.
Automatic argument truncation makes use of this function redundant.
* kexec.c (SYS_FUNC(kexec_load)): Do not invoke widen_to_ulong.
* process_vm.c (SYS_FUNC(process_vm_readv),
SYS_FUNC(process_vm_writev)): Likewise.
There is no compat (and no 32-bit version, ever) for x32 ABI, so
kernel's long type should be used for arguments' values.
The only remaining thing is a pointer to cmdline string, but it is
currently broken on x32 anyway.
* kexec.c (SYS_FUNC(kexec_file_load)): Print the cmdline_len argument
as kernel long, retrieve it via getarg_klu; use printflags64 for
printing the flags argument, retrieve it via getarg_klu.
Curiously, kexec_load uses compat on x32/n32, so its parameters should
be 4 bytes in size on these ABIs.
* kexec.c (SYS_FUNC(kexec_load)): Use widen_to_ulong for casting
parameters to proper size on x32/n32.
Before this change, all files that exist since 20th century had
copyright headers, while most files that appeared later didn't. This
change fixes the inconsistency by adding missing copyright headers.
It doesn't mean that copyright headers became maintained. In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.
* defs.h (umove_ulong_array_or_printaddr): New prototype.
* util.c (umove_ulong_array_or_printaddr): New function.
* desc.c (sys_pselect6): Use it instead of open-coding
a proxy struct parser for different personalities.
* io.c (tprint_iov_upto): Use it instead of open-coding
a struct iovec parser for different personalities.
* kexec.c (print_kexec_segments): Use it instead of open-coding
a struct kexec_segment parser for different personalities.
(print_seg): Pass arguments using an array.
* kexec.c (print_seg): New function.
(print_kexec_segments): Use it. Use printaddr and umove_or_printaddr.
(kexec_load): Use printaddr. Update for RVAL_DECODED.
Introduce SYS_FUNC macro to declare and define all syscall parsers.
* Makefile.am (BUILT_SOURCES, CLEANFILES): Add sys_func.h.
(sys_func.h): New rule.
* defs.h (SYS_FUNC_NAME, SYS_FUNC): New macros.
* linux/syscall.h: Include "sys_func.h".
[NEED_UID16_PARSERS]: Use SYS_FUNC to declare uid16 syscall parsers.
Remove other declarations.
* linux/alpha/syscallent.h (160, 161): Add sys_ prefix to osf_statfs
and osf_fstatfs syscall parsers.
* *.c: Use SYS_FUNC to define syscall parsers.
