* defs.h (RVAL_PRINT_ERR_VAL): Remove.
* ldt.c (SYS_FUNC(modify_ldt)): Return 0.
* syscall.c (syscall_exiting_trace): When printing an error,
always print struct tcb.u_rval as if RVAL_PRINT_ERR_VAL was set.
Kernel reads only entry_number field in the beginning of the
get_thread_area syscall handler. Let's replicate this behaviour.
* defs.h (enum user_desc_print_filter): New enumeration.
(print_user_desc): Add an argument for signalling which part of the
structure should be printed.
* clone.c (print_tls_arg): Update print_user_desc call.
* ldt.c (print_user_desc): Add filter argument. Print entry_number on
entering and the rest on exiting. Store entering value of the
entry_number field in order to print the updated value in the impossible
case of changed entry_number value.
(SYS_FUNC(modify_ldt), SYS_FUNC(set_thread_area)): Update
print_user_desc call.
(SYS_FUNC(get_thread_area)): Call print_user_desc with
USER_DESC_ENTERING format argument on entering and with
USER_DESC_EXITING on exiting.
* ldt.c (modify_ldt): Move parsing under entering(tcp). Check whether
return code is erroneous and set tcp->u_error appropriately along with
RVAL_PRINT_ERR_VAL flag.
Also, while we are here, let's fix print qualifiers (which should be %u
and not %d).
* ldt.c (print_user_desc): Use PRINT_FIELD_* macros for printing
structure.
(SYS_FUNC(set_thread_area)): Change field key-value separator from ":"
to "=", change print format qualifier from %d to %u.
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.
* defs.h [HAVE_STRUCT_USER_DESC] (print_user_desc): Change address
argument type from long to kernel_ureg_t.
* ldt.c [HAVE_STRUCT_USER_DESC] (print_user_desc): Likewise.
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.
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.
