| | | | | | | | | | | return value of 'asprintf' was not checked, and the flow was continuing without returning error, which could cause potential segfaults in code (mostly possible during ENOMEM case).

* break inode_path if the length of the path crosses PATH_MAXAmar Tumballi2009-07-161-0/+7
| | | | | | | | | | | a given search for path can't exceed the length of PATH_MAX in any case. Hence, its best to make sure by adding a check inside the for loop of inode_path, so that it won't enter an infinite loop. Signed-off-by: Anand V.

* mem-pool: Do not perform chunkhead2ptr on MALLOCed memoryShehjar Tikoo2009-07-061-2/+6
| | | | | | | | | | | | Memory allocated from the heap instead of the mem-pool need not under go the chunkhead to ptr conversion when returning to a mem-pool user since this address can be use directly.

| | | | | | | | | This patch is a step towards giving compatibility between the versions of GlusterFS. Now onwards, the protocol-version won't depend on release versions. In general, multiple glusterfs versions can have common protocol-version. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

| | | | | | | | | | | | | Several functions to support centralized logging: - create a logging thread upon init - gf_log submits log messages to the logging thread which in turn sends it to the server using the MOP log - on the server side, log messages from a client are written to the filename <log file name>.client-<transport-identifier> Signed-off-by: Anand V.

* libglusterfs: Add empty and NULL dirents list checksShehjar Tikoo2009-06-082-0/+12
| | | | | | | | | | | | These checks are needed in case a higher layer intends to delink the dirent list and passes a NULL pointer to fop_readdir_cbk_stub for the entries parameter. Consequently, the gf_dirent_free must guard against an empty list because the stub that is passed to it mgiht have an empty dirent list. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

| | | | | | | | | | | This is another attempt at fixing build problems on Solaris. I am told that booster build is disabled on Solaris and I know that it is disabled on Mac OS X also. Getting it to work on both these systems is now on my TODO list, mainly because on both these systems, we can have a glusterfs client running without requiring FUSE. Signed-off-by: Anand V.

* mem-pool: Restructure mem-pool behaviourShehjar Tikoo2009-05-192-31/+55
| | | | | | | | | | | | | | | | | | This commit changes mem-pool behaviour to return a directly usable address by performing the required adjustment on the address being returned. This is different from the previous behaviour where we're trying to fit into the requested size, the list_head*2 also. This is not efficient enough in terms of space but hopefully works better than not having any mem-pool at all. Besides, I am not comfortable with mem-pool meta-data and caller-useable memory area being the same because of the potential for mem-pool's data structure corruption.

| | | | | | | | | - this procedure atomically allocates a buffer and serializes dict into it. - this procedure helps avoid memory corruptions due to race conditions where in new members are added into dict between allocating a buffer for serializing and actually serializing buffer into it.
