Remove remains of solaris personality support.
This complements commit v4.10-45-gdf4dd8b.
* file.c [SPARC || SPARC64]: Remove the code related to struct solstat.
(printstat, printoldstat) [SPARC || SPARC64]: Remove.
When the syscall number returned by arch_get_scno is a mapped indirect
subcall (i.e. mapped subcall of socketcall or ipc syscall), do not
mistakenly treat it as a valid indirect subcall.
* defs.h (SCNO_IS_VALID): Treat scno with TRACE_INDIRECT_SUBCALL flag
as invalid.
* syscall.c (syscall_name): Do no shuffle scno.
(trace_syscall_entering, trace_syscall_exiting): Use
tcp->s_ent->sys_name instead of syscall_name.
(get_scno): In case of invalid syscall, allocate a dynamic struct sysent
containing an appropriate .sys_name.
* tests/nsyscalls.c (main) [SYS_socket_subcall]: Check decoding
of direct syscall number SYS_socket_subcall+1.
(main) [SYS_ipc_subcall]: Check decoding of direct syscall number
SYS_ipc_subcall+1.
Fix inconsistency between syscall and ioctl entries on sparc64.
Make layout of personalities on sparc64 the same as on other
architectures that support two personalities.
* defs.h [SPARC64] (PERSONALITY0_WORDSIZE): Change to 8.
[SPARC64] (PERSONALITY1_WORDSIZE): Change to 4.
* linux/sparc64/get_scno.c (arch_get_scno): Swap personality numbers.
* linux/sparc64/ioctls_arch1.h: Rename to ioctls_arch0.h.
* linux/sparc64/ioctls_arch0.h: Rename to ioctls_arch1.h.
* linux/sparc64/ioctls_inc0.h: Rename to ioctls_inc1.h.
* linux/sparc64/ioctls_inc1.h: Rename to ioctls_inc0.h.
This commit is an attempt to unify usage of include guards (in top-level
headers, at least). As a side note, different files with *.h extension
have different semantics: for example, printargs.h is included multiple
times in order to generate slightly varying code depending on values of
macro definitions - maybe it's better to change extension of such files
to something like *.inc.
* defs.h: Add #include guard.
* flock.h: Likewise.
* ipc_defs.h: Likewise.
* mpers_type.h: Likewise.
* printsiginfo.h: Likewise.
* ptrace.h: Likewise.
* regs.h: Likewise.
* seccomp_fprog.h: Likewise.
* gcc_compat.h: Rename the macro used for #include guard.
* msghdr.h: Likewise.
* sigevent.h: Likewise.
* kernel_types.h: Comment the trailing part of #include guard.
* xlat.h: Add missing macro definition for #include guard.
There seems to be no readily available binary packages of musl that are
sufficiently up to date to be used to build and test strace, so prepare
a suitable musl from source.
* travis-install.sh (musl-gcc): Do not add an extra repository,
do not install musl-tools and linux-musl-dev packages.
Download, build, and install a suitable musl revision instead.
* tests/attach-f-p.c Simplify communications between threads
by replacing per-thread timers with pipes.
* tests/attach-f-p.test: Do not ignore signals.
* tests/signalfd4.c (get_sigset_size): New function.
(main): Use it. Print expected output.
* tests/signalfd4.test: Use run_strace_match_diff.
* tests/signalfd4.expected: Remove.
* tests/Makefile.am (EXTRA_DIST): Remove it.
* strace.c (ptrace_attach_cmd): New variable.
(ptrace_attach_or_seize): Save last ptrace command's name
to ptrace_attach_cmd.
(attach_tcb, startup_child): Use it in error diagnostics.
This script has been created by commit v4.8-180-g0ed617b
for the one-shot job of automatic convertion of xlat structures
from *.c files to xlat/*.in files.
* generate_xlat_in.sh: Remove.
* tests/vhangup.c (main): Fix expected output for the case when
the calling process has CAP_SYS_TTY_CONFIG capability.
Reported-by: Yun-Chih Chen <b03902074@ntu.edu.tw>
* xlat/ipccalls.in: New file.
* ipc.c: New file.
* Makefile.am (libstrace_a_SOURCES): Add it.
* linux/dummy.h (sys_ipc): Remove stub alias.
* syscall.c (decode_ipc_subcall): Treat 1st argument of ipc syscall
as "unsigned int".
[S390 || S390X]: Skip ipc cubcalls that have non-zero version.
[SPARC64]: Likewise, for the native personality.
Save ipc cubcall version for later use by specific ipc parsers.
* ipc_msg.c (SYS_FUNC(msgrcv)): Handle non-zero ipc subcall version.
[SPARC64]: Handle non-ipc_kludge case for the native personality.
* linux/subcall.h (msgrcv): Change nargs from 4 to 5.
* linux/s390/syscallent.h (ipc): Change nargs from 6 to 5.
* linux/s390x/syscallent.h (ipc): Likewise.
* tests/netlink_protocol.c: Check that HAVE_SYS_XATTR_H is defined.
Include <stdlib.h> and <sys/xattr.h>.
(main): Check that system.sockprotoname attribute is supported.
