2006-08-01[PATCH] Process Events: Fix biarch compatibility issue. use __u64 timestampChandra Seetharaman1-1/+2
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.

2006-06-23[PATCH] Process Events - Header CleanupMatt Helsley1-2/+0
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.

2005-12-12[PATCH] Add timestamp field to process eventsMatt Helsley1-0/+2
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.

2005-11-30[PATCH] process events connector: uid_t gid_t size issuesMatt Helsley1-4/+4
The uid_t and gid_t fields appear to present a 32/64-bit userspace/kernel problem for some archs. This patch addresses the problem by fixing the size to the largest size for uid_t/gid_t used in the kernel. This preserves the total size of the event structure while ensuring that the layouts of the ID change event match in 32 and 64-bit kernels and applications.

2005-11-07[PATCH] Process Events ConnectorMatt Helsley1-0/+127
This patch adds a connector that reports fork, exec, id change, and exit events for all processes to userspace. It replaces the fork_advisor patch that ELSA is currently using. Applications that may find these events useful include accounting/auditing (e.g. ELSA), system activity monitoring (e.g. top), security, and resource management (e.g. CKRM).
