in the name of zero

May 31, 2007

just an update

Filed under: hermetic studies

i started out with the intention of finding out why the zero flag is ON on elf startup in my machine, but got sidetracked because i stumbled across an article “playing with binary formats” by alessandro. very fun activity he presented… i’m totally into it.

i don’t know if this is intentional, but fs/namei.c::deny_write_access(struct file *file) isn’t exported (at least) on linux 2.6.12. shame on me…

	int (*my_goddamn_deny_write)(struct file *file);
	
	/* from System.map */
	fp = (int (*)()) 0xc0166590;
	err = my_goddamn_deny_write(file);

[ update ]

i placed a cbox (on the right side) for you all visitors out there… greetings, comments are all welcome. =)
