This is needed due to apparent deviation in spelling of commit author
name in several commits.
* .mailmap: Add canonical name for Eugene Syromyatnikov.
* linux/64/ioctls_inc.h: Update from linux v4.8 using ioctls_gen.sh.
* linux/32/ioctls_inc_align32.h: Likewise.
* linux/32/ioctls_inc_align64.h: Likewise.
According to POSIX, nsops argument of semop syscall has type size_t,
but the kernel treats nsops argument of semop and semtimedop syscalls
as unsigned int.
* ipc_sem.c (tprint_sembuf_array): Change type of "count" argument
from unsigned long to unsigned int, print it using %u format.
Also fix io_cancel and io_destroy checks which did not check correct
printing of context argument properly.
* tests/aio.c (main): Update syscall checks in order to use newly
defined bogus_ctx constant.
As io_setup syscall allocates some memory using do_mmap_pgoff, and
io_destroy deallocates this memory using vm_munmap, set TRACE_MEMORY
flag for all sysentries of io_setup and io_destroy using the following
oneliner:
sed -ri '/io_setup|io_destroy/ s/0,/TM,/' linux/*/syscallent*.h
* linux/*/syscallent*.h (io_setup, io_destroy): Change sys_flags to TM.
It was incorrectly assumed that __*64 types are long long on all
platforms, despite strace having specially crafted macros in order
to handle precisely this architecture discrepancy.
The commit fixes this oversight.
* tests/aio.c (main): Use PRI__*64 macros for correct format conversion
specifiers for __*64-typed values.
* ipc_msgctl.c (SYS_FUNC(msgctl)): As msqid argument is treated as int
by the kernel, cast it to int and print it using %d format.
* ipc_sem.c (SYS_FUNC(semop), SYS_FUNC(semtimedop)): Likewise,
for semid argument.
(SYS_FUNC(semget)): Likewise, for nsems argument.
(SYS_FUNC(semctl)): Likewise, for semid and semnum arguments.
* ipc_shm.c (SYS_FUNC(shmat)): Likewise, for shmid argument.
* ipc_shmctl.c (SYS_FUNC(shmctl)): Likewise.
* ipc_msg.c (SYS_FUNC(msgget)): As key_t type in the kernel
is __kernel_key_t (i.e. int), cast key_t argument to int
and print it using %#x format.
* ipc_sem.c (SYS_FUNC(semget)): Likewise.
* ipc_shm.c (SYS_FUNC(shmget)): Likewise.
* tests/ipc_msg.c (main): Test it.
* tests/ipc_sem.c (main): Likewise.
* tests/ipc_shm.c (main): Likewise.
Kernel headers declare this field as s32, and strace prints it with %d
specifier.
* tests/sched_xetattr.c (main): Change type of sched_nice field of struct
sched_attr to int32_t, update format specifiers accordingly.
New sprintrc_grep function is sprintrc function equivalent suitable for
tests where grep-base pattern matching is employed.
* tests/tests.h (sprintrc_grep): New prototype.
* tests/sprintrc.c (enum sprintrc_fmt): New sprintrc format enumeration.
(sprintrc_ex): New function, renamed from sprintrc and updated to
support different formats.
(sprintrc): Change to use sprintrc_ex with SPRINTRC_FMT_RAW.
(sprintrc_grep): New function, calls sprintrc_ex with SPRINTRC_FMT_GREP.
Use tail_alloc with precise size of the structure.
* tests/sched_xetattr.c (main): Eliminate usage of anonymous union type.
Rename sched to sched_attr. Change type of sched_attr to struct
pointer. Use tail_alloc for sched_attr allocation, update printf
statements accrodingly.
* tests/aio.c (main): Do not pass 64-bit aio_context_t to io_submit
and io_getevents until strace learns how to print 64-bit pointers on x32
and on x86_64 for x32 personality.
As aio_context_t is treated by the kernel as a pointer,
print it using printaddr.
* aio.c (SYS_FUNC(io_setup)): Print the pointer to aio_context_t
argument using printnum_ptr.
(SYS_FUNC(io_destroy), SYS_FUNC(io_submit), SYS_FUNC(io_cancel),
SYS_FUNC(io_getevents)): Print aio_context_t argument using printaddr.
* tests/aio.c (sprint_aio_context_t): Remove.
(main): Update expected output.
This helps to avoid warnings like
"integer constant is too large for ‘long’ type"
reported by some versions of gcc on 32-bit platforms.
* tests/aio.c (main): Add ULL suffix to 64-bit constants
and cast them to unsigned long.
* tests/sched_xetscheduler.c (main): Check for decoding of invalid PID
in sched_getscheduler and sched_setscheduler, invalid address
of sched_param structure, and invalid policy value.
struct iocb contains two fields with fd semantics: aio_fildes and
aio_resfd. It is quite reasonable to use the appropriate function for
printing them (apart from just "%d").
* aio.c (print_common_flags): Add struct tcb pointer to parameter list;
use printfd for printing aio_resfd field.
(print_iocb_header): Add struct tcb pointer to parameter list;
use printfd for printing aio_fildes field.
(print_iocb): Provide tcp argument to print_iocb_header
and print_common_flags.
(SYS_FUNC(io_cancel)): Likewise.
