After updating my system (with emerge -u world) samba do not starting. smbd and nmbd daemons as well as other samba related commands (smbtree, smbstatus, smbmount, ...) crashes. Important system packages like glibc, linux-headers, libtool, udev were upgraded (samba was not upgraded). See below for complete list. I've tried re-emerge samba but without success. I'll post strace output of smbtree as attachment. Other samba related commands have similar strace outputs. Here is output which smbd and nmbd leave in /var/log/messages: Jul 16 10:20:51 amit smbd[7956]: [2005/07/16 10:20:51, 0] lib/fault.c:fault_report(36) Jul 16 10:20:51 amit smbd[7956]:

Just upgraded samba to latest unstable version 3.0.14a-r1 and it does not work too. Same crashes as previous stable 3.0.10.
Maybe this is specific problem of my system (due to -ftracer flag (?)). And it seems that it is not "bug" in Samba but in glibc. See discusion on gentoo-user (http://thread.gmane.org/gmane.linux.gentoo.user/135549). You can close this bug as INVALID or WORKSFORME if you decide. Maybe guys from toolchain will want to look so I added them to CC.
works for me ... ftracer isnt really supported in gcc-3.4 ... iirc it's much more stable in gcc-4
I can reproduce this bug in chrooted environment with fresh gentoo instalation from stage3. The main problem are the environment variables LC_COLLATE and LC_CTYPE which I have set to value sk_SK. I did following steps to reproduce the bug (doing from current gentoo environment): 1. untar stage3-amd64-2005.0.tar.bz2 and portage snapshot to some empty partion (/mnt/gentoo) 2. set USE, CFLAGS, CHOST variables in make.conf (see emerge --info) 3. set variables LC_COLLATE=sk_SK and LC_CTYPE=sk_SK (in new file - /mnt/gentoo/etc/env.d/000mybasic) 4. chroot to /mnt/gentoo as described in handbook 5. emerge --sync, choose profile, upgrade baselayout as in handbook 6. emerge -u world, emerge samba 7. run some samba command, e.g. smbtree - it should crash When I remove LC_* variables from 000mybasic and then do: 1. env-update 2. emerge binutils linux-headers glibc samba works correctly. emerge --info of chrooted environment: Portage 2.0.51.22-r1 (default-linux/amd64/2005.0, gcc-3.4.3, glibc-2.3.5-r0, 2.6.12-gentoo-r4 x86_64) ================================================================= System uname: 2.6.12-gentoo-r4 x86_64 AMD Athlon(tm) 64 Processor 3200+ Gentoo Base System version 1.6.12 dev-lang/python: 2.3.5 sys-apps/sandbox: 1.2.10 sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.5 sys-devel/binutils: 2.15.92.0.2-r10 sys-devel/libtool: 1.5.18-r1 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="amd64" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -march=athlon64 -fomit-frame-pointer -fweb -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.3/env /usr/kde/3.3/share /config /usr/kde/3.3/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/shar e/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -march=athlon64 -fomit-frame-pointer -fweb -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://ftp.belnet.be/mirror/rsync.gentoo.org/gentoo http://distfiles.gentoo.org http://www.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="amd64 3dnowex Xaw3d a52 aac aalib aim alsa avi bash-completion berkdb bitmap-fonts bluetooth bzlib cdparanoia cdr crypt cups dga dts dv dvd dvdr edl encode ethereal exif fbcon ffmpeg flac flash font-server foomaticdb fortran ftp gif gimpprint gphoto2 gpm gtk gtk2 iconv icq imagemagic imap imlib ipv6 jabber jack jbig jpeg ladcca lcms leim libcaca live lm_sensors lzw lzw-tiff mad maildir matroska mikmod mime mng mozsvg mp3 mpeg msn mule ncurses network nls nvidia ofx ogg oggvorbis opengl oscar pam pda pdflib perl png pnp portaudio ppds python qt quicktime readline real recode rtc samba sdl snmp sockets sox speex spell ssl svg tcltk tcpd theora tiff truetype truetype-fonts type1-fonts unicode usb userlocales vcd vorbis wmf wxwindows xface xmms xosd xpm xv xvmc yahoo zlib userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LANG, LC_ALL, LDFLAGS, LINGUAS, PORTDIR_OVERLAY
I can confirm that this bug is indeed real, as I have the exact same problem here. I recompiled most of my system due to the hassle with com_err and mit-krb5, and this came up after recompiling samba & glibc. I now suspect that glibc is the real culprit, but alas I'm no programmer... CFLAGS="-O2 -pipe -march=k8", gcc-3.4.4, glibc-2.3.5, binutils-2.16.1, hardened-sources-2.6.11-r15, 2.6.11-headers In my case the trace ends with /usr/lib64/gconv/IBM850.so, and replacing that file with one from stage3 tarball FIXES the problem. That is of course just a temporary fix, but will work for someone in a pinch.
Additionally, this bug crops up with every samba version now available in portage (tested), and also with samba-3.0.20pre2 (latest test release). Replacing glibc files with older versions to fix a problem like this really seems, well, I dunno :-)
Two questions: 1) How do you make sure IBM85[02].so is used ? 2) Anybody tried to remerge glibc with gcc-3.4.4 ? Or maybe upgrade to 2.3.5-r1?
Mikko, Robert: please see and respond to comment #8
From my posts, you see that I'm using glibc-2.3.5 and gcc-3.4.4 (both hardened). Upgrading to glibc-2.3.5-r1 does not solve the problem, but (in my case) replacing the IBM850.so solves it. I have both straced and gdb'd samba's corefiles many times, compiled with different CFLAGS+debug combinations. The same crash happens every time. I started a thread in the forums a while ago about this; there's more info about how I traced this crash: http://forums.gentoo.org/viewtopic-t-361176.html How should I proceed to exact the most of debugging information about this?
1. I saw that strace always ends near to open("/usr/lib64/gconv/IBM852.so", O_RDONLY) = 2 so I've tried to replace it (with the one from live CD) and it works. 2. I did not tried newer versions of glibc/gcc. I've only tried to downgrade to glibc-2.3.4.20041102-r1 but it did not work (samba still crashed).
Created attachment 64933 [details] readelf differences between a broen and working (stage3) file This is a unified diff of "readelf -a" output between the working (original stage3 tarball IBM850.so) and broken library in glibc-2.3.5-r1. Don't know if that helps, but just tell me what to do/debug and I'll do it.
seems like a hardened toolchain thing, reassigning to hardened, putting toolchain in cc.
Note that I have normal instalation, not hardened. See comment #5 and original report.
I prepared a chroot and populated its toolchain + relevant system software with the exact same versions as are on the host system. I installed from stage3 tarball, but with one exception: I used default-linux/amd64/2004.3 profile. With that exception the chroot is identical to the host system (same USE and CFLAGS etc). Compiling glibc-2.3.5 and glibc-2.3.5-r1 in this chroot both produce a working IBM850.so file. Meaning that samba works if I copy over the file from chroot to the host system. This leads me to believe that not everything is yet right with the 2005.0 profile (maybe multilib setup is botched somehow). This, and the inability to compile glibc-2.3.5-r1 again under itself (long double error during linuxthreads configure, conftest complains about a corrupted shared library) in my opinion point to a more fundamental problem (perhaps incorrect 32-bit library handling).
Samba was working fine until I emerged updated to samba-3.0.20-r1 last night, now I get the same error messages as the original post.
Replacing /usr/lib64/gconv/IBM852.so by the one in stage3 does not work for me. I'm wondering wether this would not come from what causes from misuses of pointer to integers. For me, it seems to crash in nt_printing.c (upgrade_to_version_4)? I found in the callback it uses this: int32 size_new_sec; ... make_sec_desc(..., &size_new_sec); This function requires a size_t* argument, not an int32* and on amd64, this is not the same thing size_t being unsigned long int i.e. uint64 ! Seems that there are other occurences of such a problem.
Confirmed. If I replace int32 by size_t at nt-printing.c line 345, it does not crash anymore. I filed #3084 at bugzilla.samba.org
(In reply to comment #16) > Samba was working fine until I emerged updated to samba-3.0.20-r1 last night, > now I get the same error messages as the original post. Are they going to downgrade Samba 3.0.20 in ~amd64 portage?
Dowgrading would not help. The bug has been fixed upstream.
3.0.20-r1 doesn't work for me either, 3.0.14a-r3 does. Shouldn't 3.0.20-r1 be masked for amd64?
can you post the URL to the bug and/or patch ? either way, not a bug in toolchain and seems to be a bug which comes up on 64bit arches, not just amd64

Thanks: I just bumped samba-3.0.20b, which includes the fix. Could you please check it?
(In reply to comment #24) > Thanks: I just bumped samba-3.0.20b, which includes the fix. Could you please > check it? samba-3.0.20b does NOT fix the problem for me. glibc-2.3.5-r3, gcc-3.4.4, samba-3.0.20b --> same problem as before. In strace output, as soon as execution hits "/usr/lib64/gconv/IBM850.so", samba throws a SIGSEGV. As before, replacing the library with one from stage3 tarball FIXES the crash. Just let me know what information you need to fix this.

If you still have the problem w/ 3.0.24-r3, then reopen the bug. Cannot reproduce at all.
I can not reproduce it either (with samba 3.0.24-r3 and glibc-2.5-r3). It seems fixed.
