This is mostly based off recent UCX additions to their patcher:
https://github.com/openucx/ucx/pull/2703
They added triggers for
* mmap when (flags & MAP_FIXED) && (addr != NULL)
* shmat when (shmflg & SHM_REMAP) && (shmaddr != NULL)
Beyond that I noticed they already had a trigger for
* madvise when (advice == MADV_FREE)
that we didn't so I added that.
And the other main thing is we didn't really have shmat/shmdt
active for some systems because we only had a path for
syscall(SYS_shmdt, ) but we needed to also have a path for
syscall(SYS_ipc, IPCOP_shmdt, ) and same for shmat.
