Format FDs in strace logs
Normal files display their path in the current mount namespace:
I0410 10:57:54.964196 216336 x:0] [ 1] ls X read(0x3 /proc/filesystems, 0x55cee3bdb2c0 "nodev\t9p\nnodev\tdevpts \nnodev\tdevtmpfs\nnodev\tproc\nnodev\tramdiskfs\nnodev\tsysfs\nnodev\ttmpfs\n", 0x1000) = 0x58 (24.462?s)
AT_FDCWD includes the CWD:
I0411 12:58:48.278427 1526 x:0] [ 1] stat_test E newfstatat(AT_FDCWD /home/prattmic, 0x55ea719b564e /proc/self, 0x7ef5cefc2be8, 0x0)
Sockets (and other non-vfs files) display an inode number (like
/proc/PID/fd):
I0410 10:54:38.909123 207684 x:0] [ 1] nc E bind(0x3 socket:[1], 0x55b5a1652040 {Family: AF_INET, Addr: , Port: 8080}, 0x10)
I also fixed a few syscall args that should be Path.
