From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.2.1) Gecko/20010901 Description of problem: I have a box that has been running Redhat linux for serveral years now. I installed 6.1 and have since upgraded to 6.2, 7.0, 7.1 and now 7.2. Samba has worked fine for all installations up to now. The server (manny) can still share file shares with no problem and printer shares can be browsed with no problem. When something is printed to the share, however, nothing is printed and the following error is reported in /var/logs/samba/meche.log (meche was the machine that was trying to print) [2001/10/26 16:27:12, 0] lib/util.c:smb_panic(1101) PANIC: internal error [2001/10/26 16:57:08, 0] lib/fault.c:fault_report(40) =============================================================== [2001/10/26 16:57:08, 0] lib/fault.c:fault_report(41) INTERNAL ERROR: Signal 11 in pid 12582 (2.2.1a) Please read the file BUGS.txt in the distribution [2001/10/26 16:57:08, 0] lib/fault.c:fault_report(43) =============================================================== [2001/10/26 16:57:08, 0] lib/util.c:smb_panic(1101) PANIC: internal error [2001/10/26 16:57:09, 0] lib/fault.c:fault_report(40) =============================================================== [2001/10/26 16:57:09, 0] lib/fault.c:fault_report(41) INTERNAL ERROR: Signal 11 in pid 12585 (2.2.1a) Please read the file BUGS.txt in the distribution [2001/10/26 16:57:09, 0] lib/fault.c:fault_report(43) =============================================================== [2001/10/26 16:57:09, 0] lib/util.c:smb_panic(1101) PANIC: internal error Version-Release number of selected component (if applicable): samba-2.2.1a-4 How reproducible: Always Steps to Reproduce: 1.allow all printers to be shared in /etc/samba/smb.conf: [global] printcap name = /etc/printcap load printers = yes [printers] comment = All Printers path = /var/spool/samba browseable = no # Set public = yes to allow user 'guest account' to print guest ok = yes printable = yes public = yes writable = yes create mode = 0700 2.Browse available printer shares and attempt to print (I'm using a win98 box to browse and print) 3.Note print failure (windows dialog saying print failed) and examine server logs Additional Information A complete copy of my smb.conf can be found at: http://www.kleemann.org/crap/smb.conf
This has been fixed in the development version under CVS. There is a SEGV because of pointer pointing to subsequently free'ed memory. Here is a patch: --- samba-2.2.1a/source/smbd/sec_ctx.c.segv Fri Jul 6 12:02:03 2001 +++ samba-2.2.1a/source/smbd/sec_ctx.c Thu Nov 1 00:03:20 2001 @@ -356,7 +356,7 @@ current_user.gid = gid; current_user.ngroups = ngroups; current_user.groups = groups; - current_user.nt_user_token = token; + current_user.nt_user_token = ctx_p->token; } /****************************************************************************
This patch seems to already be included in samba 2.2.2-1, available from Rawhide.
Updating the 7.2 samba SRPM with the above patch, recompiling, and reinstalling, fixed the problem. Thanks!
