* Fix pipe syscall name in return probe.Mark Wielaard2010-03-241-1/+5
| | | | | * tapset/syscalls2.stp (syscall.pipe.return): If @defined($flags) then use it to determine correct name.
* Removed unneeded convenience variables in syscall.pipe.return.David Smith2010-03-231-5/+1
| | | | | * tapset/syscalls2.stp: Removed unneeded 'flags' and 'flag_str' convenience variables in syscall.pipe.return probe.
* Support signalfd4 in syscalls2.stp tapset.Mark Wielaard2010-03-211-5/+17
| | | | | | | * tapset/aux_syscalls.stp (_signalfd4_flags_str): New utility function. * tapset/syscalls2.stp (syscall.signalfd[.return]): Handle signalfd4 variant when available. * testsuite/systemtap.syscall/signalfd.c: New test.
* Add ia64 pipe result support. Relax pipe syscall test a little.Mark Wielaard2010-03-191-1/+17
| | | | | | * tapset/syscalls2.stp (syscall.pipe.return): ia64 provides pipe0, pipe1 results through (user) registers. * testsuite/systemtap.syscall/pipe.c: Only expect zero as input fildes.
* Merge syscall.pipe and syscall.pipe2 to get around "nesting".Mark Wielaard2010-03-191-41/+24
| | | | | * tapset/syscalls2.stp (syscall.pipe[2][.return]): Merge into syscall.pipe and syscall.pipe.return. Set name according to flags.
* Reindent syscall2.stp pipe[2][.return] to follow unify formatting rules.Mark Wielaard2010-03-191-72/+54
| | | | See commit c0c1cc.
* PR11402 Support pipe2 syscall.Mark Wielaard2010-03-191-0/+40
| | | | | | | | | The pipe2() was added to Linux in version 2.6.27. It is a variant of the normal pipe syscall, but takes an extra flags argument which can be the ORed value of O_NONBLOCK and O_CLOEXEC. * tapset/aux_syscalls.stp (_sys_pipe2_flag_str:string): New helper function. * tapset/syscalls2.stp (syscall.pipe2, syscall.pipe2.return): New probes.
* Make pipe file descriptors available in syscall.pipe[.return].Mark Wielaard2010-03-191-1/+34
| | | | | | | | | | | The actual value of the pipe file descriptors can be interesting, especially in the syscall.pipe.return probe. This can be done without any embedded C now using @cast. So don't use _fildes_u() anymore. _fildes_u in aux_syscall.stp is still retained because it is used in nd_syscalls2.stp for pipe. * tapset/syscalls2.stp (syscall.pipe, syscall.pipe.return): Add pipe1 pipe2 convenience variables. Don't use _fildes_u for argstr anymore.
* Use @defined() in syscall.pipe to select whether fildes_uaddr is available.Mark Wielaard2010-03-191-20/+10
| | | | | | * tapset/aux_syscalls.stp (syscall.pipe): Remove architecture dependent probe definitions. Newer gcc make $fildes available on more arches. Use @defined($fildes) to select on which ones.
* Fixed BZ 568032 by adding support for sys_ia64_pipe.David Smith2010-03-181-2/+9
| | | | | * tapset/syscalls2.stp: Added support for 'sys_ia64_pipe' so that the syscall.pipe probe works correctly under RHEL5.5.
* PR 11338 (partial): Used '@defined()' in syscall tapsets.David Smith2010-03-051-58/+29
| | | | | | | | | | * tapset/syscalls.stp: Used '@defined()' to remove kernel version checks. * tapset/syscalls2.stp: Ditto. * tapset/x86_64/syscalls.stp: Ditto. * tapset/nd_syscalls.stp: Updated to match tapset/syscalls.stp. * tapset/nd_syscalls2.stp: Updated to match tapset/syscalls2.stp. * tapset/x86_64/nd_syscalls.stp: Updated to match tapset/x86_64/syscalls.stp.
* PR 11167 fixed by adding compat_sys_sigaction to the syscall.sigaction32 probe.David Smith2010-01-131-2/+4
| | | | | | * tapset/syscalls2.stp (syscall.sigaction32): Added kernel.function("compat_sys_sigaction"). (syscall.sigaction32.return): Ditto.
* Fix PR11160 by handling ppc syscall.sigaction32 correctly.David Smith2010-01-131-1/+1
| | | | | | | | | | * tapset/aux_syscalls.stp (_struct_old_sigaction32_u): New function. * tapset/syscalls2.stp (syscall.sigaction32): Uses new _struct_old_sigaction32() function to provide a human readable version of the sigaction argument. * testsuite/systemtap.syscall/test.tcl (run_one_test): Use additional C flags when pre-processing test files to better determine which tests are valid on which platforms.
* Fixed PR 11163 so that syscall.readv/syscall.writev puts fd in argstr for ppc.David Smith2010-01-121-10/+0
| | | | | | | | * tapset/syscalls2.stp (syscall.readv): Removed old ppc hack. (syscall.writev): Ditto. * tapset/nd_syscalls2.stp (nd_syscall.readv): Removed mention of old ppc hack. (nd_syscall.writev): Ditto.
* Fixed PR 11162 by removing extra 'buf_uaddr' assignment.David Smith2010-01-121-1/+0
| | | | | * tapset/syscalls2.stp (syscall.pwrite32): Remove extra 'buf_uaddr' assignment.
* PR5434: Fix syscall.nfsservctl.Przemyslaw Pawelczyk2009-10-131-0/+8
| | | | | | | | Use proper $vars according to CONFIG_NFSD and CONFIG_COMPAT in syscall.nfsservctl and mask it out along with return probe if CONFIG_NFSD != "[ym]" && CONFIG_COMPAT != "y". * tapset/syscalls2.stp (syscall.nfsservctl): Fix it.
* Add the .call modifier to syscall entry probes.Przemyslaw Pawelczyk2009-10-121-355/+355
| | | | | | | | | | | | | | | | | | | | Inline functions do not have an indentifiable return point and require kernel built using VTA-enabled gcc to get tracking of variables. OTOH syscall functions are very rarely inlined (depending on the compiler mood), therefore filtering probes to include only non-inlined functions ensures consistent behavior between different kernels. This removes the problem of inaccessible variables in inlined syscalls that is described in comments #6-9 to PR5890 and gives us the status quo w.r.t. syscall probing, because before the commit solving PR10572 (b7478964) inline instances were masked anyway by non-inline ones. You can check whether you have inlined syscalls using following command: $ stap -l 'kernel.function("sys_*"),kernel.function("compat_sys_*")' \ 2>&1 -vvv | awk '/^selected inline/{print $5}' * tapset/syscalls.stp: Add .call to all entry probes. * tapset/syscalls2.stp: Ditto.
* PR10613 sys32_ustat is renamed compat_sys_ustat in 2.6.30 kernel.Mark Wielaard2009-09-071-1/+11
| | | | | | | | | | Note that the new compat_sys_ustat is asmlinkage and has a differently named argument for the user struct. * tapset/syscalls2.stp (syscall.ustat32): Add compat_sys_ustat variant. (syscall.ustat.return): Likewise. * tapset/nd_syscalls2.stp (nd_syscall.ustat32): Likewise. (nd_syscall.ustat.return): Likewise.
* PR4186 cont'd: option #2: standardize on kernel ARCH/SUBARCH throughoutFrank Ch. Eigler2009-08-251-3/+3

* Fix alignment of probe aliases in syscalls(|2).stp.Przemyslaw Pawelczyk2009-05-191-355/+355
| | | | | | | Align probe points in probe aliases to equal sign using spaces as it's already done in nd_syscalls.stp. Signed-off-by: Josh Stone <jistone@redhat.com>
* Unify formatting of syscalls.stp and syscalls2.stp.Przemyslaw Pawelczyk2009-05-191-559/+754
| | | | | | | | | | | | | | | Rules: - Specify probe points for aliases starting from the alias declaration line and with one probe point per line. - Use K&R indent style -- probe alias/point/function opening brace goes to the line following the declaration, other opening braces are kept on the same line as the control statements. - Indent using tabs. - Surround operators with spaces. - Put spaces after commas. - Avoid trailing whitespaces.
