2010-03-23ceph: clean up handle_cap_grant, handle_caps wrt session mutexSage Weil
Drop session mutex unconditionally in handle_cap_grant, and do the check_caps from the handle_cap_grant helper. This avoids using a magic return value. Also avoid using a flag variable in the IMPORT case and call check_caps at the appropriate point. Signed-off-by: Sage Weil <sage@newdream.net>
2010-03-23ceph: fix session locking in handle_caps, ceph_check_capsSage Weil
Passing a session pointer to ceph_check_caps() used to mean it would leave the session mutex locked. That wasn't always possible if it wasn't passed CHECK_CAPS_AUTHONLY. If could unlock the passed session and lock a differet session mutex, which was clearly wrong, and also emitted a warning when it a racing CPU retook it and we did an unlock from the wrong context. This was only a problem when there was more than one MDS. First, make ceph_check_caps unconditionally drop the session mutex, so that it is free to lock other sessions as needed. Then adjust the one caller that passes in a session (handle_cap_grant) accordingly. Signed-off-by: Sage Weil <sage@newdream.net>
2010-03-23ceph: drop unnecessary WARN_ON in caps migrationSage Weil
If we don't have the exported cap it's because we already released it. No need to WARN. Signed-off-by: Sage Weil <sage@newdream.net>
2010-03-23ceph: fix null pointer deref of r_osd in debug outputSage Weil
This causes an oops when debug output is enabled and we kick an osd request with no current r_osd (sometime after an osd failure). Check the pointer before dereferencing. Signed-off-by: Sage Weil <sage@newdream.net>
2010-03-23ceph: clean up service ticket decodingSage Weil
Previously we would decode state directly into our current ticket_handler. This is problematic if for some reason we fail to decode, because we end up with half new state and half old state. We are probably already in bad shape if we get an update we can't decode, but we may as well be tidy anyway. Decode into new_* temporaries and update the ticket_handler only on success. Signed-off-by: Sage Weil <sage@newdream.net>
2010-03-20ceph: release old ticket_blob bufferSage Weil
Release the old ticket_blob buffer when we get an updated service ticket from the monitor. Previously these were getting leaked. Signed-off-by: Sage Weil <sage@newdream.net>
2010-03-20ceph: fix authenticator buffer size calculationSage Weil
The buffer size was incorrectly calculated for the ceph_x_encrypt() encapsulated ticket blob. Use a helper (with correct arithmetic) and BUG out if we were wrong. Signed-off-by: Sage Weil <sage@newdream.net>
2010-03-20ceph: fix authenticator timeoutSage Weil
We were failing to reconnect to services due to an old authenticator, even though we had the new ticket, because we weren't properly retrying the connect handshake, because we were calling an old/incorrect helper that left in_base_pos incorrect. The result was a failure to reconnect to the OSD or MDS (with an authentication error) if the MDS restarted after the service had been up a few hours (long enough for the original authenticator to be invalid). This was only a problem if the AUTH_X authentication was enabled. Now that the 'negotiate' and 'connect' stages are fully separated, we should use the prepare_read_connect() helper instead, and remove the obsolete one. Signed-off-by: Sage Weil <sage@newdream.net>
2010-03-20ceph: fix inode removal from snap realm when racing with migrationSage Weil
When an inode was dropped while being migrated between two MDSs, i_cap_exporting_issued was non-zero such that issue caps were non-zero and __ceph_is_any_caps(ci) was true. This prevented the inode from being removed from the snap realm, even as it was dropped from the cache. Fix this by dropping any residual i_snap_realm ref in destroy_inode. Signed-off-by: Sage Weil <sage@newdream.net>
2010-03-20ceph: add missing locking to protect i_snap_realm_item during splitSage Weil
All ci->i_snap_realm_item/realm->inodes_with_caps manipulation should be protected by realm->inodes_with_caps_lock. This bug would have only bit us in a rare race with a realm split (during some snap creations). Signed-off-by: Sage Weil <sage@newdream.net>
2010-03-20ceph: implemented caps should always be superset of issued capsSage Weil
Added assertion, and cleared one case where the implemented caps were not following the issued caps. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>

2010-03-19USB: Fix usb_fill_int_urb for SuperSpeed devicesMatthew Wilcox
USB 3 and Wireless USB specify a logarithmic encoding of the endpoint interval that matches the USB 2 specification. usb_fill_int_urb() didn't know that and was filling in the interval as if it was USB 1.1. Fix usb_fill_int_urb() for SuperSpeed devices, but leave the wireless case alone, because David Vrabel wants to keep the old encoding. Update the struct urb kernel doc to note that SuperSpeed URBs must have urb->interval specified in microframes. Add a missing break statement in the usb_submit_urb() interrupt URB checking, since wireless USB and SuperSpeed USB encode urb->interval differently. This allows xHCI roothubs to actually register with khubd.
