samba - Jun 2015 - vfs_fruit kernel panic 10.9.5 when saving from adobe illustrator cc

dear list,

thanks for the great fruit speed-improvements. but...

server config:
debian 8 jessie
sernet samba 4.2.2 packages

here we see a problem that might not only be fruits problem but
results in macosx 10.9.5 crashing with a kernel panic when saving from 
adobe illustrator cc or cc 2014:
(does not happen when saving from photoshop cc or cc2014)

       Kernel Extensions in backtrace:
com.apple.filesystems.smbfs(2.0.3)[EC68D5F4-45EA-379A-B723-AEEDE9C94055]@0xffffff7fac647000->0xffffff7fac692fff
             dependency: 
com.apple.kec.corecrypto(1.0)[DB137B94-65D2-32AF-B5BC-80A360E104C3]@0xffffff7fab362000
             dependency: 
com.apple.kext.triggers(1.0)[A7018A2E-1C0C-37B8-9382-67786A396EAF]@0xffffff7fabd1d000


does occur on third or fourth save.

happens with smb.conf like this:

[global]
    workgroup = domain.com
    server string = %h server
    log level = 2
    os level = 60
    security = user
    case sensitive = no
    domain logons = yes
    domain master = no
    usershare max shares = 0
    unix extensions = no
    wide links = no
    wins server = 172.20.4.7
    encrypt passwords = true
    guest account = nobody
    logon path     hide special files = no
    printcap name = cups
    max protocol = SMB3
    use sendfile = true
    vfs object = catia fruit streams_xattr acl_xattr
    fruit:encoding = native
    reset on zero vc = yes

    ldap ssl = off

    ldap admin dn = "cn=admin,dc=domain,dc=com"
    passdb backend = ldapsam:"ldap://is.domain.com
ldap://it.domain.com"
    ldap machine suffix = ou=systems
    ldap suffix = dc=domain,dc=com
    ldap timeout = 30

    idmap config * : backend = tdb
    idmap config * : range = 1000000-1999999

    idmap config domain : backend = ldap
    idmap config domain : range = 3000000-3999999
    idmap config domain : read only = yes
    idmap config domain : ldap_url = ldap://is.domain.com/
    idmap config domain : ldap_base_dn = ou=idmaps,dc=domain,dc=com
    idmap config domain : ldap_user_dn = cn=admin,dc=domain,dc=com

#======================= Share Definitions ======================
[test-volume]
     path = /daten/pv50/test-volume
     valid users = @support user1 user2 user3
     read only = No
     inherit permissions = Yes
     inherit acls = Yes
     map archive = No
     map readonly = no
     store dos attributes = Yes

what can i do to provide more info?

cheers,
sascha

probably the same issue as:
<https://bugzilla.samba.org/show_bug.cgi?id=11303>

If it's the same issue, you should be able to reproduce it with
vfs_streams_depot instead of vfs_fruit.

hey ralph,

thanks for your hint.
i dont have problems with photoshop.
but if catia, fruit and streams are disabled on the share, at least 
illustrator throws error -5000
and states that it was not able to save a preview of the image.

so with catia, fruit and streams enabled this might be the point where 
illustrator crashes the smbfs.

but i was able to avoid a crash when editing the /etc/nsmb.conf on my 
mac with following content:

[global]
file_ids_off=yes

whatever that means (?) but it is stable now

regarding vfs_depot:
with above option enabled on my mac: illustrator throws error -43, 
preview could not be saved... (no crash)
without above option: the same error -43 (no crash)
error -43 is thrown on every save.

maybe this file_ids_off is helpful!?

cheers,
sascha
