From the very first commit when CRIS architecture support was introduced
and up to this comment that ends the agony of this non-functional code,
this support was incomplete and could never be compiled.
* Makefile.am (EXTRA_DIST): Remove linux/crisv*.
* clone.c: Remove CRISV* checks.
* configure.ac ($host_cpu == cris*): Remove.
* linux/crisv10: Remove.
* linux/crisv32: Likewise.
Fixes: v4.5.18-77-gea0e6e8 ("CRIS support by Hinko Kocevar ...")
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.
Limit the number of files where <asm/unistd.h> is included
to only those few that need it.
* defs.h: Do not include <asm/unistd.h>.
* clone.c: Include <asm/unistd.h>.
* strace.c: Likewise.
* syscall.c: Likewise.
* util.c: Likewise.
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.
The flags argument is defined in kernel as unsigned long,
so change its decoding to avoid truncation.
* clone.c (SYS_FUNC(clone)): Change flags type from unsigned long
to kernel_ureg_t, print it using printflags64 instead of printflags.
* defs.h (printaddr_ull): Rename to printaddr_klu, change argument
type from unsigned long long to kernel_ulong_t. All callers updated.
(getarg_ull): Rename to getarg_klu, change return value type
from unsigned long long to kernel_ulong_t. All callers updated.
(PRI_kl, PRI_kld, PRI_klu, PRI_klx): New macros.
* bjm.c (SYS_FUNC(init_module)): Print kernel_ulong_t type using
PRI_klu format.
* desc.c (SYS_FUNC(pselect6)): Likewise.
* fadvise.c (SYS_FUNC(fadvise64)): Likewise.
* lookup_dcookie.c (SYS_FUNC(lookup_dcookie)): Likewise.
* mq.c (SYS_FUNC(mq_timedsend), SYS_FUNC(mq_timedreceive)): Likewise.
* kcmp.c (SYS_FUNC(kcmp)): Print kernel_ulong_t type using
PRI_klx format.
* keyctl.c (SYS_FUNC(keyctl)): Likewise.
* pkeys.c (SYS_FUNC(pkey_alloc)): Likewise.
* prctl.c (print_prctl_args, SYS_FUNC(prctl), SYS_FUNC(arch_prctl)):
Print kernel_ulong_t type using PRI_kld, PRI_klu, or PRI_klx format.
* util.c (printaddr_ull): Rename to printaddr_klu, change argument
type from unsigned long long to kernel_ulong_t, print it using
PRI_klx format.
(getarg_ull): Rename to getarg_klu, change return value type
from unsigned long long to kernel_ulong_t, print it using
PRI_klx format.
Kernel declares flags parameter as long and looks like x32 and n32
implement no compat for this call.
* clone.c (SYS_FUNC(unshare)): Use getarg_ull and printflags64 for
obtaining and parsing flags parameter.
Not all clone flags could be passed to unshare (see check_unshare_flags
function in kernel/fork.c).
* xlat/unshare_flags.in: New file.
* clone.c (SYS_FUNC(unshare)): Use unshare_flags for printing flags
parameter.
nstype is not flag set but specific type value against which it is
compared in kernel (see kernel/nsproxy.c, SYSCALL_DEFINE2(setns, ...)).
* xlat/setns_types.in: New file.
* clone.c: Use printxval and setns_types for nstype parameter.
Migrate to __NR_* the last user of SYS_* macros provided
by <sys/syscall.h>.
* clone.c [IA64] (ARG_STACKSIZE, ARG_PTID, ARG_CTID, ARG_TLS): Replace
SYS_clone2 with __NR_clone2.
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.
* clone.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* process.c: Move sys_clone, sys_setns, sys_unshare, sys_fork, and
related code to clone.c.
