* cluster/stripe: fix {set/get}xattr query for dirs/symlinkVenky Shankar2012-03-181-16/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the following problems: * ENOENT returned for getxattr (xtime) on symlinks Non-data entities are created only on the first subvolume but getxattr fop winds to all subvols. This results in all subvols except the first one to return ENOENT which is propogated down the stack. * ENODATA returned for getxattr (xtime) on directory setxattr calls always wind to the first stripe subvolume. xtime getxattr invocation winds to all subvolumes but the xattr is present in only the first one, resulting in all subvols except the first one to return ENODATA. Fix For symlinks getxattr now always winds to the first subvol and for directories setxattr sets the xattr on all subvols. NOTE For directories the all-subvol-wind in setxattr is done only when request is from a special client (client-pid == -1) Change-Id: I9236345ef319506770d2034b840ee4ac04704b21 BUG: 801394 Signed-off-by: Venky Shankar <vshankar@redhat.com> Reviewed-on: http://review.gluster.com/2948 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Shishir Gowda <shishirng@gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | This is the new version of the patch by Kaushik at review.gluster.com/699 The following new option types have been introduced: * GF_OPTION_TYPE_INTERNET_ADDRESS_LIST * GF_OPTION_TYPE_PRIORITY_LIST * GF_OPTION_TYPE_SIZE_LIST and option types of several options in translators have been updated to use the new types. valid_internet_address(), valid_ipv4_address() & valid_ipv6_address() functions has been updated for * wildcard matching. Previously used standalone wildcard address checking functions have been removed. Changes have been done to stripe translator to correctly set, update and use stripe-blocksize. Also minimum value for block-size has been set to 16KB.

* posix: handle some internal behavior in posix_mknod()Amar Tumballi2012-02-161-0/+5
| | | | | | | | | | | | | | | | | | | | assume a case of link() systemcall, which is handled in distribute by creating a 'linkfile' in hashed subvolume, if the 'oldloc' is present in different subvolume. we have same 'gfid' for the linkfile as that of file for consistency. Now, a file with multiple hardlinks, we may end up with 'hardlinked' linkfiles. dht create linkfile using 'mknod()' fop, and as now posix_mknod() is not equipped to handle this situation. this patch fixes the situation by looking at the 'internal' key set in the dictionary to differentiate the call which originates from inside with regular system calls.
