libceph: bump CEPH_MSG_MAX_DATA_LEN

2018-11-21T08:27:42Z

commit 94e6992bb560be8bffb47f287194adf070b57695 upstream. If the read is large enough, we end up spinning in the messenger: libceph: osd0 192.168.122.1:6801 io error libceph: osd0 192.168.122.1:6801 io error libceph: osd0 192.168.122.1:6801 io error This is a receive side limit, so only reads were affected.

libceph: add nocephx_sign_messages option

2015-11-02T22:37:46Z

Support for message signing was merged into 3.19, along with nocephx_require_signatures option. But, all that option does is allow the kernel client to talk to clusters that don't support MSG_AUTH feature bit. That's pretty useless, given that it's been supported since bobtail. Meanwhile, if one disables message signing on the server side with "cephx sign messages = false", it becomes impossible to use the kernel client since it expects messages to be signed if MSG_AUTH was negotiated. Add nocephx_sign_messages option to support this use case. Signed-off-by: Ilya Dryomov

libceph: stop duplicating client fields in messenger

supported_features and required_features serve no purpose at all, while nocrc and tcp_nodelay belong to ceph_options::flags. Signed-off-by: Ilya Dryomov

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
