[PATCH] Process Events: Fix biarch compatibility issue. use __u64 timestamp

2006-07-31T20:28:36+00:00

Events sent by Process Events Connector from a 64-bit kernel are not binary compatible with a 32-bit userspace program because the "timestamp" field (struct timespec) is not arch independent. This affects the fields that follow "timestamp" as they will be be off by 8 bytes. This is a problem for 32-bit userspace programs running with 64-bit kernels on ppc64, s390, x86-64.. any "biarch" system. Matt had submitted a different solution to lkml as an RFC earlier. We have since switched to a solution recommended by Evgeniy Polyakov. This patch fixes the problem by changing the timestamp to be a __u64, which stores the number of nanoseconds. Tested on a x86_64 system with both 32 bit application and 64 bit application and on a i386 system.

[PATCH] connector-exports

2006-06-23T14:43:06+00:00

Put the connector exports at the functions so people can see them in context. Cc: Evgeniy Polyakov Cc: Greg KH Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Process Events - Header Cleanup

2006-06-23T14:43:06+00:00

Move connector header include to precisely where it's needed. Remove unused time.h header file as well. This was leftover from previous iterations of the process events patches.

[CONNECTOR]: Initialize subsystem earlier.

2006-06-20T06:42:53+00:00

Attached patch declares connector init function as subsys_init() and returns -EAGAIN in case connector is not initialized yet. Signed-off-by: Evgeniy Polyakov Signed-off-by: David S. Miller

[CONNECTOR]: Fix warning in cn_queue.c

2006-06-18T04:29:43+00:00

cn_queue.c:130: warning: value computed is not used There is no point in testing the atomic value if the result is thrown away. From Evgeniy: It was created to put implicit smp barrier, but it is not needed there. Signed-off-by: Andreas Schwab Signed-off-by: Evgeniy Polyakov Signed-off-by: David S. Miller

[PATCH] sem2mutex: drivers: raw, connector, dcdbas, ppp_generic

2006-03-23T15:38:10+00:00

Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well. Signed-off-by: Arjan van de Ven Signed-off-by: Ingo Molnar Cc: Stephen Rothwell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[CONNECTOR]: Use netlink_has_listeners() to avoind unnecessary allocations.

2006-03-21T06:21:40+00:00

Return -ESRCH from cn_netlink_send() when there are not listeners, just as it could be done by netlink_broadcast(). Propagate netlink_broadcast() error back to the caller. Signed-off-by: Evgeniy Polyakov Signed-off-by: David S. Miller

[PATCH] Switch getnstimestamp() calls to ktime_get_ts()

2006-01-10T16:01:39+00:00

Use ktime_get_ts() to take the timestamp instead of getnstimestamp(). This patch prepares to remove getnstimestamp() by switching its only user to a different function with almost exactly the same code.

[PATCH] drivers/connector/cn_proc.c typos

2006-01-09T04:13:58+00:00

The parameter to put_cpu_var() is unreferenced by the implementation, and the compiler doesn't try to comprehend comments, so this wouldn't cause any problem, but if bugged me enough to post a fix :-) Signed-off-by: David S. Miller Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Add timestamp field to process events

2005-12-12T16:57:42+00:00

This adds a timestamp field to the events sent via the process event connector. The timestamp allows listeners to accurately account the duration(s) between a process' events and offers strong means with which to determine the order of events with respect to a given task while also avoiding the addition of per-task data. This alters the size and layout of the event structure and hence would break compatibility if process events connector as it stands in 2.6.15-rc2 were released as a mainline kernel.
