* Fixed nd_syscalls 'sys32_mmap2' problem on newer kernels.David Smith2010-03-221-2/+2
| | | | | * tapset/x86_64/nd_syscalls.stp: Made 'sys32_mmap2' probe point optional, since it doesn't exist on newer kernels.
* Partial fix for pr 11388 by adding 'sys_mmap_pgoff' support.David Smith2010-03-221-2/+4
| | | | | | * tapset/i386/nd_syscalls.stp: Add support for 'sys_mmap_pgoff' (which is what the mmap syscall uses). * tapset/x86_64/nd_syscalls.stp: Ditto.
* Partial fix for pr 11388 by adding 'sys_mmap_pgoff' support.David Smith2010-03-221-4/+6
| | | | | | * tapset/i386/syscalls.stp: Add support for 'sys_mmap_pgoff' (which is what the mmap syscall uses). * tapset/x86_64/syscalls.stp: Ditto.
* Match syscall.pipe32 with regular syscall.pipe[2] output.Mark Wielaard2010-03-211-1/+34
| | | | | * tapset/x86_64/syscalls.stp (syscall.pipe32[.return]): Define same variables and match argstr with regular syscall.pipe.
* PR 11338 (partial): Used '@defined()' in syscall tapsets.David Smith2010-03-052-14/+4
| | | | | | | | | | * 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.
* Fixed PR 11269 by properly handling mmap syscall 'fd' argument.David Smith2010-02-232-8/+16
| | | | | | | | | | | | | | * testsuite/systemtap.syscall/mmap.c (main): Added mprotect and mremap testing (along with testing of anonymous maps). * tapset/i386/syscalls.stp: In mmap probes, handle the fact that the kernel gets an unsigned long 'fd', but the user-side passes a signed int. * tapset/i386/nd_syscalls.stp: Ditto. * tapset/ia64/syscalls.stp: Ditto. * tapset/powerpc/nd_syscalls.stp: Ditto. * tapset/powerpc/syscalls.stp: Ditto. * tapset/x86_64/nd_syscalls.stp: Ditto. * tapset/x86_64/syscalls.stp: Ditto.
* rhbz#563114 Make syscall.pipe sys32_pipe probe alias optional on x86_64.Mark Wielaard2010-02-091-5/+3
| | | | | | | | | Some distributions might have backported the pipe fd leak patch and removed the sys32_pipe kernel function even before 2.6.32. So make the probe alias optional instead of relying on a version check. * tapset/x86_64/syscalls.stp (syscall.pipe): Make alias optional. (syscall.pipe.return): Likewise.
* Make probe syscall.mmap2 optionalWenji Huang2010-01-041-3/+3
| | | | The function sys32_mmap2 is removed since 2.6.33.
* Make sys32_pipe probe available only before 2.6.32Wenji Huang2009-09-292-0/+4
| | | | | * tapset/x86_64/nd_syscalls.stp: Switch by kernel version. * tapset/x86_64/syscalls.stp: Ditto.
* Correct a few comments to match the codeJosh Stone2009-08-261-1/+1
| | | | | | | * tapset/conversions.stp (kernel_long, kernel_int, kernel_short, kernel_char): All are actually using kread(), not deref(). * tapset/i386/registers.stp (_stp_arg): Ditto. * tapset/x86_64/registers.stp (_stp_arg): Ditto.
* Add $arch/nd_syscalls.stpJosh Stone2009-06-021-0/+187
| | | | | These are all the dwarfless analogs to $arch/syscalls.stp. (Only i686 and x86_64 have been tested...)
* Clean up the formatting of $arch/syscalls.stpJosh Stone2009-06-021-18/+36
|
* Use embedded-C for empty functionsJosh Stone2009-05-221-4/+2
| | | | | | | | | | The functions asmlinkage() and fastcall() are used to help access syscall parameters on i686. All other archs don't need this, but they still define empty functions to shield the callers from arch details. However, stap issues warnings for empty script-level functions. This patch changes them to "%{ /* pure */ %}" so there's no complaint, and they will still get optimized away.
* Add safety checks to _stp_get_register_by_offset()Josh Stone2009-03-091-0/+10
| | | | | This now checks that CONTEXT->regs actually exists, and that the requested offset is in the correct range.
* Add empty argstr to syscall.vm86_warning to stop warnings on probe syscall.*Mark Wielaard2008-09-161-0/+1
|
* Changed method of getting the value of $syscall.David Smith2008-07-151-4/+0
| | | | | | | | | | | | | 2008-07-14 David Smith <dsmith@redhat.com> * tapsets.cxx (utrace_var_expanding_copy_visitor::visit_target_symbol): Synthesize a function to get the value of $syscall. 2008-07-14 David Smith <dsmith@redhat.com> * i686/registers.stp: Removed syscall_nr function. * x86_64/registers.stp: Ditto.
* Add 'pure' to embedded-C functions that deserve itJosh Stone2008-06-131-4/+4
|
* Fixed utrace probe '$syscall' handling.David Smith2008-06-091-0/+4
| | | | | | | | | | | | | 2008-06-09 David Smith <dsmith@redhat.com> * tapsets.cxx (utrace_var_expanding_copy_visitor::visit_target_symbol): Calls 'syscall_nr' to get the value of '$syscall'. 2008-06-09 David Smith <dsmith@redhat.com> * x86_64/registers.stp (syscall_nr): Added syscall_nr function. * i686/registers.stp (syscall_nr): Ditto.
* Fix PR 6582: verify CONTEXT->regs in [u_]register()Jim Keniston2008-05-291-0/+4
|
* Fix regparm() on i686 & x86_64.Josh Stone2008-05-271-2/+2
| | | | | It doesn't seem that regparm() is actually used, but I saw compilation errors when I compiled with -u.
* PR6538: tapset changesFrank Ch. Eigler2008-05-201-1/+1
|
* Merge commit 'origin/dwarfless'Jim Keniston2008-05-121-0/+243
|\ | | | | | | PR 4311 - Function boundary tracing without debuginfo: Phases 1 and 2
| * Replaced [u_]arg() with [u]int_arg(), [u]long_arg(), {s|u}32_arg(),Jim Keniston2008-05-051-33/+115
| | | | | | | | | | | | | | {s|u}64_arg(), etc. Added asmlinkage(), fastcall(), regparm(). Dealt with some surprises -- e.g., rax is ZERO-extended eax. Seems to work well with -m32 and -m64 user apps, and with a (small) dwarfless subset of syscall.stp.
| * Added support for register(), u_register(), arg(), and u_arg() functions.Jim Keniston2008-05-011-0/+86
|/ | | | | Still missing: arg64(), _stp_copy_from_user stack, .linkage clause, tests, docs.

* 2007-08-15 Martin Hunt <hunt@redhat.com>hunt2007-08-151-0/+50
| | | | | | | | | * x86_64/syscalls.stp: Add support for sys32_mmap[2], sys32_vm86_warning, and sys32_pipe. * s390x/syscalls.stp (get_mmap_args): Move to aux_syscalls. * aux_syscalls.stp (get_mmap_args): Moved here. * syscalls.stp: Add sys32_alarm. * syscalls2.stp: Add sys32_uname.
