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.
