https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=274198 --- Comment #3 from Ivan Rozhuk <rozhuk.im@gmail.com> --- (In reply to Mark Johnston from comment #2) > NAMEI events are generated by namei(). symlink(2) doesn't call namei() on the second parameter, so this patch doesn't really make sense. vn_getcwd() and few other places call ktrnamei(). I do not understand why call ktrnamei() directly is wrong. > ktrace(2) in general does not show you arbitrary system call parameters. It is enough for my purposes to get few NAMEI, like: 47 ktrace CALL execve(0x7fffffffdfb6,0x7fffffffd970,0x7fffffffd980) 47 ktrace NAMI "build-install_media.sh" 47 ktrace NAMI "/bin/sh" 47 ktrace NAMI "/libexec/ld-elf.so.1" 47 sh RET execve JUSTRETURN > But if you want to see parameters, you can also just use truss or dtrace. I need get list of all files that was read with abs path. I wrote tool to parse ktrace file, it keep context of process and convert path to abs on logging and filter crap out of src dir. I can not use truss without modifications to get same results. -- You are receiving this mail because: You are the assignee for the bug.
