libceph: enable ceph in a non-default network namespace

2015-07-09T17:30:34Z

Grab a reference on a network namespace of the 'rbd map' (in case of rbd) or 'mount' (in case of ceph) process and use that to open sockets instead of always using init_net and bailing if network namespace is anything but init_net. Be careful to not share struct ceph_client instances between different namespaces and don't add any code in the !CONFIG_NET_NS case. This is based on a patch from Hong Zhiguo .

libceph: store timeouts in jiffies, verify user input

2015-06-25T08:49:29Z

There are currently three libceph-level timeouts that the user can specify on mount: mount_timeout, osd_idle_ttl and osdkeepalive. All of these are in seconds and no checking is done on user input: negative values are accepted, we multiply them all by HZ which may or may not overflow, arbitrarily large jiffies then get added together, etc. There is also a bug in the way mount_timeout=0 is handled. It's supposed to mean "infinite timeout", but that's not how wait.h APIs treat it and so __ceph_open_session() for example will busy loop without much chance of being interrupted if none of ceph-mons are there. Fix all this by verifying user input, storing timeouts capped by msecs_to_jiffies() in jiffies and using the new ceph_timeout_jiffies() helper for all user-specified waits to handle infinite timeouts correctly.

libceph, ceph: split ceph_show_options()

2015-04-20T15:55:38Z

Split ceph_show_options() into two pieces and move the piece responsible for printing client (libceph) options into net/ceph. This way people adding a libceph option wouldn't have to remember to update code in fs/ceph. Signed-off-by: Ilya Dryomov
