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.
|
| |
|
|
|
| |
* control.c (_stp_ctl_write_cmd): Add support for STP_BULK.
* transport_msgs.h (enum): Add STP_BULK.
|
| | |
|
| |
|
|
| |
* control.c (_stp_register_ctl_channel): Fix mode of cmd file.
|
| | |
|
| | |
|
| |
|
|
|
|
| |
* control.c: Change default buffer number and size.
(_stp_ctl_write): Add debug statements. Check size of
message to avoid overwriting buffer.
|
| |
|
|
|
|
| |
* control.c (_stp_ctl_open_cmd): Set _stp_pid.
(stp_ctl_close_cmd): Clear _stp_pid.
* transport.h: Declare _stp_pid;
|
| |
|
|
|
|
|
|
| |
* 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.

* 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.
