getent repeatedly attempts to open DB_CONFIG

[Anand Kumria]

Binary package hint: libc6

Hi,

I was doing some testing of db files as sources of information for maps (as in using 'db' in nsswitch.conf).

Checking to see how getent was getting the information, I straced and saw:

open("/var/lib/misc/passwd.db", O_RDONLY|O_LARGEFILE) = 4
open("DB_CONFIG", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/stat", O_RDONLY) = 4
open("/var/lib/misc/passwd.db", O_RDONLY|O_LARGEFILE) = 4
open("/var/lib/misc/passwd.db", O_RDONLY|O_LARGEFILE) = 4
open("DB_CONFIG", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/stat", O_RDONLY) = 4
open("/var/lib/misc/passwd.db", O_RDONLY|O_LARGEFILE) = 4
open("/var/lib/misc/passwd.db", O_RDONLY|O_LARGEFILE) = 4
open("DB_CONFIG", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/stat", O_RDONLY) = 4
open("/var/lib/misc/passwd.db", O_RDONLY|O_LARGEFILE) = 4
open("/var/lib/misc/passwd.db", O_RDONLY|O_LARGEFILE) = 4
open("DB_CONFIG", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/proc/stat", O_RDONLY) = 4

I will not comment on the multiple openings of the DB file -- but it does seem odd that 'DB_CONFIG' is repeatedly being open (or attempted to be being opened).

Is that a configuration variable that has leaked out?

Thanks,
Anand
