I've used nss-mysql. Everything worked OK (configs and DB are OK I guess). But one day, I've run emerge -u world and since then strange things happens. When I have in my /etc/nsswitch.conf only passwd: files shadow: files group: files everything goes OK. but when I use files mysql at each line, su and login freezes. The strange thing is, that getent passwd and getent shadow works perfectly. It gets all info, that it needs. And most wierd is, that when I strace su it gets all info. here is my strace output (strace su - lnovy (lnovy is my test user)): [cut] read(3, "\23\0\0\3", 4) = 4 read(3, "\4user\3uid\3\v\0\0\1\3\3\1\0\0", 19) = 19 read(3, "\20\0\0\4", 4) = 4 read(3, "\0\4NULL\3\4\0\0\1\6\3\0\0\0", 16) = 16 read(3, "\30\0\0\5", 4) = 4 read(3, "\4user\10realname\3 \0\0\1\375\3\1\0\0", 24) = 24 read(3, "\25\0\0\6", 4) = 4 read(3, "\4user\5shell\3\24\0\0\1\375\3\1\0\0", 21) = 21 read(3, "\27\0\0\7", 4) = 4 read(3, "\4user\7homedir\3 \0\0\1\375\3\1\0\0", 23) = 23 read(3, "\23\0\0\10", 4) = 4 read(3, "\4user\3gid\3\v\0\0\1\3\3\1\0\0", 19) = 19 read(3, "\1\0\0\t", 4) = 4 read(3, "\376", 1) = 1 brk(0) = 0x8064000 brk(0x8066000) = 0x8066000 read(3, "1\0\0\n", 4) = 4 read(3, "\5lnovy\0041006\373\nLukas Novy\t/bin/bas"..., 49) = 49 read(3, "\1\0\0\v", 4) = 4 read(3, "\376", 1) = 1 open("/etc/shadow", O_RDONLY) = 4 fcntl64(4, F_GETFD) = 0 fcntl64(4, F_SETFD, FD_CLOEXEC) = 0 fstat64(4, {st_mode=S_IFREG|0600, st_size=530, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x4426c000 read(4, "root:$1$ss8/nB1S$TCVNC4qihM48Tkh"..., 4096) = 530 read(4, "", 4096) = 0 close(4) = 0 munmap(0x4426c000, 4096) = 0 stat64("/etc/nss-mysql/nss-mysql-root.conf", {st_mode=S_IFREG|0666, st_size=4814, ...}) = 0 time([1061050489]) = 1061050489 open("/etc/localtime", O_RDONLY) = 4 fstat64(4, {st_mode=S_IFREG|0644, st_size=806, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x4426c000 read(4, "TZif\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\6\0\0\0\6\0"..., 4096) = 806 close(4) = 0 munmap(0x4426c000, 4096) = 0 getpid() = 10161 rt_sigprocmask(SIG_SETMASK, NULL, [RTMIN], 8) = 0 rt_sigsuspend([] <unfinished ...> I've even tried to recompile whole machine (from beginning!!! not just recompile some packages) and problem stays :( Am I really so stupid?

I can confirm this- the exact same thing happened to me. The strace ends at the same place. Maybe my emerge info will show some correlation.

Martin Filip: change your root password, you've just exposed it here. either of you (both preferably): set nsswitch.conf to only source from files, then do: getent -s mysql passwd getent -s mysql shadow getent -s mysql group if any of those fail to return the data they should, or crash, please attach the strace of them. if the above doesn't produce an error, then try: getent -s mysql passwd lnovy getent -s mysql shadow lnovy next of all, if you don't have nscd running, repeat the above with nscd running, if you do have it running, repeat without it running (if that works for your situation. I know nscd is required for nss_ldap).
Ok, did it. There's no difference (except for pid/time values) between the nscd and non-nscd straces, so i'll omit them. The three files are catted together (delimited in an obvious way) so I don't have to create 3 attachements or tar them (and make them non-browser-viewable).

whoa, go back and read the instructions after the openssl update, including run revdep-rebuild and clean up the openssl-0.9.6 stuff. then see if it still happens (I don't think it will).
Er, I haven't upgraded to 0.9.7 at all yet- still on .6k. Should I upgrade? (revdep only has gnucash and openoffice-bin, neither of which matter for this)
it was a testing machine with very simple testing password :)
err, I assumed that based on the fact that martin said he did 'emerge -u world' and you said things were the same for you. Can you look back and see what recent updates have been done to: gcc, glibc, nss_mysql, mysql (I'm trying to trace the bug to one of those).
sorry, i should be more clear- the first version I of nss-mysql I ever emerged was the current one- I've never had it working. Here are the versions I'm using, though: mysql-4.0.14-r2 nss-mysql-0.43-r1 nss-3.8 gcc-3.2.3-r2 glibc-2.3.2-r1 USE flags as above. I'm also most of the way through a revdep remerge for openssl (not really prompted by this- just decided that now was the time), so maybe something will change there (but I doubt it). Also, 0.9.7 is currently in ~x86, which I don't use automatically. (I upgrade programs I use on a regular basis, but I don't usually upgrade to libraries from ~x86 unless one of those is pulled in by a program upgrade).
Just wondering, you guys DID follow the instructions after the nss-mysql install? Namely "ebuild /var/db/pkg/sys-libs/nss-mysql-0.43-r1/nss-mysql-0.43-r1.ebuild config"
indeed. Here's a chunk of the mysql query log (wrapped, this time). 031113 23:03:29 35 Connect nss@localhost on nss_mysql 35 Query select groups.group_name,groups.gid,groups.group_password,user.user_name from groups LEFT JOIN user_group on groups.group_id=user_group.group_id LEFT JOIN user on user_group.user_id=user.user_id and user.status = 'A' where 1 = 1 and groups.status = 'A' 35 Quit So it's querying ok, or so it seems.
No activity for over a year. Is this still an issue?
