* Cleanup. Renamed _stp_{un}lock_debugfs() to _stp_{un}lock_transport_dir().David Smith2009-02-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 2009-02-12 David Smith <dsmith@redhat.com> * transport.c (_stp_lock_transport_dir): Renamed from _stp_lock_debugfs(), since on older kernels this actually uses procfs. (_stp_unlock_transport_dir): Renamed from _stp_unlock_debugfs(), since on older kernels this actually uses procfs. (_stp_lock_transport_dir): Changed _stp_lock_debugfs()/_stp_unlock_debugfs() to _stp_lock_transport_dir()/_stp_unlock_transport_dir(). * transport.h: Ditto. Also added _stp_transport_init() prototype. * utt.c (utt_remove_root): Changed _stp_lock_debugfs()/_stp_unlock_debugfs() to _stp_lock_transport_dir()/_stp_unlock_transport_dir(). * relayfs.c (_stp_remove_relay_root): Ditto. 2009-02-12 David Smith <dsmith@redhat.com> * procfs.c (_stp_rmdir_proc_module): Changed _stp_lock_debugfs()/_stp_unlock_debugfs() to _stp_lock_transport_dir()/_stp_unlock_transport_dir(). (_stp_mkdir_proc_module): Ditto.
* Use 'static' as much as possibleJosh Stone2009-01-281-6/+6
| | | | | | | | | | This change just inserts 'static' on runtime, tapset, and generated C functions and globals, so the compiler can do a better job of optimizing. My tests with small scripts show ~10% reduction in compile time and ~20% reduction in module size. Larger scripts may show less benefit, but I expect purely positive results.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge from setuid-branch. Changes also by Martin Hunt <hunt@redhat.com>. * control.c (_stp_ctl_write): Make sure we don't overflow. (_stp_ctl_open_cmd): Do not allow multiple opens of the control file. (_stp_ctl_write_cmd): Once STP_START is received, ignore everything except STP_EXIT. Create another state variable "initialized". Don't respond to STP_SYMBOLS or STP_MODULES unless initialized is 0. Also check that current pid is the same as the pid that did insmod. (_stp_register_ctl_channel): Bug fix - sets owner/group after checking for NULL. * procfs.c (_stp_ctl_write): Make sure we don't overflow. (_stp_ctl_open_cmd): Do not allow multiple opens of the control file. (_stp_ctl_write_cmd): Once STP_START is received, ignore everything except STP_EXIT. Create another state variable "initialized". Don't respond to STP_SYMBOLS or STP_MODULES unless initialized is 0. Also check that current pid is the same as the pid that did insmod. (_stp_register_ctl_channel): Set ownership of cmd file and percpu files for bulkmode. * relayfs.c (utt_trace_setup): Set ownership of percpu files. Improved error handling. (utt_trace_remove): Improved error checking. * utt.c (utt_remove_tree): Improved error checking. (utt_trace_cleanup): Ditto. (utt_create_buf_file_callback): Set file ownership. (utt_create_global_buf_file_callback): Set file ownership. * transport.h: Delcare _stp_uid, _stp_gid, and _stp_init_pid. * transport.c (_stp_transport_init): Set _stp_uid, _stp_gid, and _stp_init_pid.
* 2007-04-27 Martin Hunt <hunt@redhat.com>hunt2007-04-271-8/+4
| | | | | | | * utt.c (utt_trace_cleanup): Remove free of utt->sequence. (utt_dropped_open): PR 4415. Use STAPCONF_INODE_PRIVATE to detect correct inode struct. (utt_trace_setup): Do not allocate utt->sequence.
* 2007-03-26 Martin Hunt <hunt@redhat.com>hunt2007-03-261-11/+29
| | | | | | | | * symbols.c (_stp_do_module): If a module has no symbols, just return NULL instead of an errorcode. * control.c, procfs.c, relayfs.c, transport.c, utt.c, utt.h: Revert back to using systemtap/modulename instead of systemtap_pid.
* 2007-03-14 Martin Hunt <hunt@redhat.com>hunt2007-03-141-0/+253
* transport_msgs.h: ifdef old messages as such. Add support for new transport. * relayfs.c: Simplify and add new interface to look like utt. * utt.[ch]: New files. Similar to the proposed utt interface. These setup and teardown relayfs on debugfs. * control.c: New file. Implements a simple control channel. A small subset of procfs.c. * procfs.c: This is now only used for old kernels lacking newer relayfs. Change STP_RELAYFS to STP_BULKMODE. Use new messages from transport_msgs.h. Don't support RELAYFS_CHANNEL_VERSION >= 4. CHanges all control channel functions to new names. Use pids instead of module names in /proc names.
