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

libceph: tcp_nodelay support

libceph: nuke ceph_kvfree()

2014-12-17T17:09:50Z

Use kvfree() from linux/mm.h instead, which is identical. Also fix the ceph_buffer comment: we will allocate with kmalloc() up to 32k - the value of PAGE_ALLOC_COSTLY_ORDER, but that really is just an implementation detail so don't mention it at all. Signed-off-by: Ilya Dryomov
