Being a wrapper around <linux/ioctl.h>, <sys/ioctl.h> brings
no benefits for parser of VIDIOC_* ioctls.
* v4l2.c: Include <linux/ioctl.h> instead of <sys/ioctl.h>.
Remove erroneous use of verbose(tcp) as a printing limit
for already fetched members of siginfo_t structure.
* printsiginfo.h (printsiginfo): Remove boolean argument.
* printsiginfo.c (printsigval): Remove boolean argument, print
si_int and si_ptr members unconditionally. All callers changed.
(print_si_info): Remove boolean argument, print si_utime and si_stime
members unconditionally. All callers changed.
(printsiginfo): Remove boolean argument. All callers changed.
Fix build on systems without HAVE_DECL_V4L2_CTRL_TYPE_STRING or
V4L2_CTRL_CLASS_CAMERA.
* tests/ioctl_v4l2.c (main) [VIDIOC_S_EXT_CTRLS]: Disable part of the
test if [!HAVE_DECL_V4L2_CTRL_TYPE_STRING].
Replace V4L2_CTRL_CLASS_CAMERA with V4L2_CTRL_CLASS_USER.
htole32 function is not portable enough.
* v4l2.c (print_pixelformat): Rewrite initialization of pixel format
union without using of htole32.
* tests/ioctl_v4l2.c (main): Likewise.
The data argument of PTRACE_PEEKSIGINFO request is a pointer
to siginfo_t array.
* printsiginfo.c (print_siginfo_t): New function.
(print_siginfo_array): New mpers printer.
* process.c (SYS_FUNC(ptrace)): Print data argument of
PTRACE_PEEKSIGINFO request using print_siginfo_array.
As flags argument has a long integer type, print it using printflags64
because printflags takes unsigned int argument.
* process.c (SYS_FUNC(ptrace)): Print PTRACE_O_* flags
using printflags64.
The addr argument of PTRACE_PEEKSIGINFO request is a pointer to
a struct ptrace_peeksiginfo_args.
* process.c: Include "xlat/ptrace_peeksiginfo_flags.h".
(SYS_FUNC(ptrace)): Print addr argument of PTRACE_PEEKSIGINFO request
as a struct ptrace_peeksiginfo_args.
* xlat/ptrace_peeksiginfo_flags.in: New file.
For PTRACE_GETSIGMASK and PTRACE_SETSIGMASK requests, addr argument
contains the size of the buffer pointed to by data argument.
For PTRACE_SECCOMP_GET_FILTER request, addr argument contains
an offset counter.
* process.c (SYS_FUNC(ptrace)): Print addr argument of
PTRACE_GETSIGMASK, PTRACE_SETSIGMASK, and PTRACE_SECCOMP_GET_FILTER
requests using %lu format.
On sparc, kernel ignores data argument of PTRACE_GETREGS,
PTRACE_SETREGS, PTRACE_GETFPREGS, and PTRACE_SETFPREGS requests.
* process.c (SYS_FUNC(ptrace)) [SPARC || SPARC64]: Return RVAL_DECODED
right after printing addr argument if request is one of PTRACE_GETREGS,
PTRACE_SETREGS, PTRACE_GETFPREGS, or PTRACE_SETFPREGS.
As kernel ignores addr and data arguments of PTRACE_ATTACH,
PTRACE_INTERRUPT, PTRACE_KILL, and PTRACE_LISTEN request,
we do not print them either.
* process.c (SYS_FUNC(ptrace)): After printing pid argument, return
RVAL_DECODED if request is one of PTRACE_ATTACH, PTRACE_INTERRUPT,
PTRACE_KILL, or PTRACE_LISTEN.
As kernel ignores arguments of PTRACE_TRACEME request,
we do not print them either.
* process.c (SYS_FUNC(ptrace)): If request is PTRACE_TRACEME,
return early with RVAL_DECODED.
As first argument of ptrace syscall has a long integer type, print
it using printxval64 because printxval takes unsigned int argument.
* process.c (SYS_FUNC(ptrace)): Change type of "request" variable
from "long" to "unsigned long", print it using printxval64 instead
of printxval.
* printsiginfo.c (print_si_info): Explicitly cast si_syscall member
of siginfo_t that has type "int" to "unsigned int", to avoid sign
extension when passed to syscall_name function.
* tests/xattr.c: Check decoding of all xattr family syscalls.
* tests/xattr.test: Use run_strace_match_diff.
* tests/xattr.expected: Remove.
* tests/Makefile.am (EXTRA_DIST): Remove it.
* tests/print_quoted_string.c (print_quoted_memory): New function.
(print_quoted_string): Use it.
* tests/tests.h (print_quoted_memory): New prototype.
* xattr.c (print_xattr_val): Do not take insize into account, print it
as unsigned long.
Do not decode xattr values of size larger than XATTR_SIZE_MAX.
Use static buffer for fetching xattr values.
(print_xattr_list): Do not decode string when size is zero.
Decode the ioctls associated with the userfaultfd fd.
Note that they tend to read from and also return result in it's data
structure.
* configure.ac (AC_CHECK_HEADERS): Add linux/userfaultfd.h.
* userfaultfd.c [HAVE_LINUX_USERFAULTFD_H]: Add ioctl decoder.
* defs.h (uffdio_ioctl): New prototype.
* ioctl.c (ioctl_decode) [HAVE_LINUX_USERFAULTFD_H]: Wire in
uffdio_ioctl.
* xlat/uffd_*.in: Create flag xlat for all the IOCTLs.
* m4/ax_code_coverage.m4: Update to serial 16.
* Makefile.am (CODE_COVERAGE_LCOV_OPTIONS): Remove.
(CODE_COVERAGE_GENHTML_OPTIONS): Update, add prefix.
(CODE_COVERAGE_BRANCH_COVERAGE): Set to 1.
* tests/strace-ff.expected: New file.
* tests/Makefile.am (EXTRA_DIST): Add it.
* tests/strace-ff.test: Use it. Check that no other output files
have been created.
This header file was added in glibc-2.3.2,
so it's safe to assume its availability.
* configure.ac (AC_CHECK_HEADERS): Remove sys/epoll.h.
* epoll.c: Include <sys/epoll.h> unconditionally.
Compile [HAVE_SYS_EPOLL_H] code unconditionally.
* tests/epoll_ctl.c: Do not check for HAVE_SYS_EPOLL_H.
* tests/epoll_wait.c: Likewise.
Allow nanosleep(2) to spend 10% more time to make the test suite
more reliable on slow systems.
* tests/count.test: Treat 1.1 seconds as valid output.
* tests/strace-T.expected: Likewise.
* tests/strace-r.expected: Likewise.
