https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211141 Fukang Chen <loader@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |loader@FreeBSD.org --- Comment #9 from Fukang Chen <loader@FreeBSD.org> --- Short answer: /etc/master.passwd contains a new user _ypldap which wasn't added into /etc/pwd.db during the upgrade to 11.0. How to repeat: # svnlite cat svn://svn.freebsd.org/base/release/10.3.0/etc/master.passwd > /etc/master.passwd # pwd_mkdb -p master.passwd # svnlite cat svn://svn.freebsd.org/base/release/11.0.1/etc/master.passwd > /etc/master.passwd # pw useradd _tss -u 601 -g 601 -L daemon -c "TrouSerS user" -d /var/empty -s /usr/sbin/nologin pw: user '_tss' disappeared during update Why getpwnam(3) can't find the user '_tss' in /etc/pwd.db? There are three copies of the original data in /etc/pwd.db, - key pw_name field prepended by the _PW_KEYBYNAME - key pw_uid field prepended by the _PW_KEYBYUID - key line number in the original file prepended by the _PW_KEYBYNUM and getpwnam(3) searches the database using the thrid key: line number https://svnweb.freebsd.org/base/release/11.0.1/lib/libc/gen/getpwent.c?view=markup#l1842 10.3 /etc/master.passwd 23 hast:*:845:845::0:0:HAST unprivileged user:/var/empty:/usr/sbin/nologin 24 nobody:*:65534:65534::0:0:Unprivileged user:/nonexistent:/usr/sbin/nologin 10.3 /etc/pwd.db B htonl(23) => hast B htonl(24) => nobody when running "pw useradd _tss -u" on 11.0, pwd_mkdb(8) inserts the '_tss' user with the current line number as the key 11.0 /etc/master.passwd: 23 _ypldap:*:160:160::0:0:YP LDAP unprivileged user:/var/empty:/usr/sbin/nologin 24 hast:*:845:845::0:0:HAST unprivileged user:/var/empty:/usr/sbin/nologin 25 nobody:*:65534:65534::0:0:Unprivileged user:/nonexistent:/usr/sbin/nologin 26 _tss:*:601:601:daemon:0:0:TrouSerS user:/var/empty:/usr/sbin/nologin 11.0 /etc/pwd.db B htonl(23) => hast B htonl(24) => nobody B htonl(26) => _tss getpwnam(3) stopped after it tried to fetch the key 'B htonl(25)' :P https://svnweb.freebsd.org/base/release/11.0.1/lib/libc/gen/getpwent.c?view=markup#l1858 -- You are receiving this mail because: You are on the CC list for the bug.
