I've got a really unique problem. Running xeno-bk changeset 1364, I get random filesystem/bash globbing problems in dom0. Same system under 2.4.26 without xeno, no issues at all. In this case the dom0 distribution is slackware, running ext3, on an Adaptec AIC-7892P U160/m scsi controller. The problem manifests itself most easily with 'ls': """ root@durandal:~# ls /var/adm/packages/ aaa_base-10.0.0-noarch-1 guile-1.6.4-i486-1 pango-1.4.0-i486-1 aaa_elflibs-9.2.0-i486-1 gzip-1.3.3-i386-2 pciutils-2.1.11-i486-5 acpid-1.0.3-i486-1 hdparm-5.5-i486-1 pcre-4.5-i486-2 ... """ works as expected. """ root@durandal:~# ls /var/adm/packages/* : : No such file or directory : : No such file or directory ... """ fails, as does: """ root@durandal:~# cd /var/log/packages/ root@durandal:/var/log/packages# ls * : : No such file or directory ... """ Now things get really strange: """ root@durandal:/var/log/packages# for x in *; do echo $x; done aaa_base-10.0.0-noarch-1 aaa_elflibs-9.2.0-i486-1 acpid-1.0.3-i486-1 at-3.1.8-i486-2 ... root@durandal:/var/log/packages# echo * aaa_base-10.0.0-noarch-1 aaa_elflibs-9.2.0-i486-1 acpid-1.0.3-i486-1 ... root@durandal:/var/log/packages# ls `echo *` : : No such file or directory : : No such file or directory ... root@durandal:/var/log/packages# strace ls * : : command not found root@durandal:/var/log/packages# cd root@durandal:# strace ls /var/log/packages/* : : command not found root@durandal:~# ls * /usr/bin/ls: *: No such file or directory root@durandal:~# strace ls * execve("/usr/bin/ls", ["ls", "*"], [/* 28 vars */]) = 0 brk(0) = 0x805a000 ... stat64("*", 0x805b6f4) = -1 ENOENT (No such file or directory) lstat64("*", 0x805b6f4) = -1 ENOENT (No such file or directory) write(2, "ls: ", 4ls: ) = 4 write(2, "*", 1*) = 1 open("/usr/share/locale/en_US/LC_MESSAGES/libc.mo", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/share/locale/en/LC_MESSAGES/libc.mo", O_RDONLY) = -1 ENOENT (No such file or directory) write(2, ": No such file or directory", 27: No such file or directory) = 27 write(2, "\n", 1 """ So strace only works in SOME of the directories that exhibit this problem, and when it fails, it's really trying to stat a literal '*' - the bash globbing fails randomly. Normally I'd accept this as being a borked install that I'm trying to run as dom0, but none of this behavior exhibits itself under the 2.4.26 stock kernel. I did a make clean and a fresh make world to be sure I didn't have any old object files laying around, no change in the behavior. The filesystem fsck -f's clean under both xeno and non-xeno. -m ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
