Subject: [PATCH 00/14] tracing: add compat syscall support v3
Date: Tue, 16 Mar 2010 13:46:08 -0400 [thread overview]
Message-ID: <cover.1268749695.git.jbaron@redhat.com> (raw)
Hi,
Re-post to add infrastructure for compat syscall event tracing support. This
patch series also adds x86_64 arch specific support as an example consumer
of the new infrastructure.
Arches can request compat syscall tracing by setting:
__HAVE_ARCH_FTRACE_COMPAT_SYSCALLS, if CONFIG_COMPAT and CONFIG_FTRACE_SYSCALLS
are set. Arches then need to implement the following interfaces:
1) int is_compat_task(void);
- most arches seem to have this already
2) unsigned long arch_compat_syscall_addr(int nr);
- returns a pointer to the compat syscall entry corresponding to syscall 'nr'
3) int NR_syscalls_compat;
- number of entries in the compat syscall table.
thanks,
-Jason
Changes in v3:
- create a separate "compat_syscalls" event subsystem
- ARCH_COMPAT_SYSCALL_DEFINE#N() tacks "sys32" to start of syscall name
- COMPAT_SYSCALL_DEFINE#N() tacks "compat_sys" to start of syscall name
- both above macros create perf events as: [enter|exit]_compat_sys_blah
- non-compat syscall naming changes to: [enter|exit]_sys_blah
- removes any unreferenced compat syscalls from debugfs
Heiko Carstens (1):
compat: have generic is_compat_task for !CONFIG_COMPAT
Jason Baron (13):
x86: add NR_syscalls_compat, make ia32 syscall table visible

tracing: remove syscall bitmaps in preparation for compat support
tracing: move __start_ftrace_events and __stop_ftrace_events to
header file
tracing: add tracing support for compat syscalls
syscalls: add ARCH_COMPAT_SYSCALL_DEFINE()
x86, compat: convert ia32 layer to use
syscalls: add new COMPAT_SYSCALL_DEFINE#N() macro
compat: convert to use COMPAT_SYSCALL_DEFINE#N()
compat: convert fs compat to use COMPAT_SYSCALL_DEFINE#N() macros
tags: recognize compat syscalls
cleanup: remove arg from TRACE_SYS_ENTER_PROFILE_INIT() macro
