libglusterfs: add glusterfs-acl.h to Makefile.am

2013-10-01T02:04:03+00:00

Without this, glusterfs-acl.h is left out of 'make dist'
and building RPM fails.

gNFS: Incorrect NFS ACL encoding for XFS

2013-09-29T23:54:37+00:00

Problem:
Incorrect NFS ACL encoding causes "system.posix_acl_default"
setxattr failure on bricks on XFS file system. XFS (potentially
others?) doesn't understand when the 0x10 prefix is added to the
ACL type field for default ACLs (which the Linux NFS client adds)
which causes setfacl()->setxattr() to fail silently. NFS client
adds NFS_ACL_DEFAULT(0x1000) for default ACL.

FIX:
Mask the prefix (added by NFS client) OFF, so the setfacl is not
rejected when it hits the FS.

core: block unused signals in created threads

2013-09-25T08:33:16+00:00

Block all signal except those which are set for explicit handling
in glusterfs_signals_setup(). Since thread spawning code in
libglusterfs and xlators can get called from application threads
when used through libgfapi, it is necessary to do this blocking.

logging: Expose set_log_file_path() in libglusterfs.

2013-09-24T19:00:54+00:00

This patch also changes the behavior of glfs_set_logging().
If logfile argument is not provided to glfs_set_logging(),
libgfapi uses set_log_file_path() to create a logfile.

parser: use private namespace 'graphyy' instead of 'yy'

2013-09-22T06:45:09+00:00

This can cause linker errors when accessing glusterfs through
libgfapi if the caller also uses a parser with 'yy' prefix.

rpcsvc: allocate large auxgid list on demand

2013-09-17T18:44:21+00:00

For rpc requests having large aux group list, allocate large list
on demand. Else use small static array by default.

Without this patch, glusterfsd allocates 140+MB of resident memory
just to get started and initialized.

parser: make the parser thread safe.

2013-09-07T00:54:10+00:00

The volfile parser thread safe by guarding the parsing phase
in a mutex. Thread safety becomes a problem when there are multiple
glfs_t objects created by gfapi and all of them potentially parse
the respective volfiles at the same time.

glusterfsd: Round robin DNS should not be relied upon with

2013-09-06T22:56:34+00:00

config service availability for clients.

Backupvolfile server as it stands is slow and prone to errors
with mount script and its combination with RRDNS. Instead in
theory it should use all the available nodes in 'trusted pool'
by default (Right now we don't have a mechanism in place for
this)

Nevertheless this patch provides a scenario where a list of
volfile-server can be provided on command as shown below

-----------------------------------------------------------------
$ glusterfs -s server1 .. -s serverN --volfile-id= \
      
-----------------------------------------------------------------
                   OR
-----------------------------------------------------------------
$ mount -t glusterfs -obackup-volfile-servers=: \
      :...: :/ 
-----------------------------------------------------------------

Here ':' is used as a separator for mount script parsing

Now these will be remembered and recursively attempted for
fetching vol-file until exhausted. This would ensure that the
clients get 'volume' configs in a consistent manner avoiding the
need to poll through RRDNS.
