[PATCH 6.5 501/550] rxrpc: Fix two connection reaping bugs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Howells <dhowells@xxxxxxxxxx>

[ Upstream commit 61e4a86600029e6e8d468d1fad6b6c749bebed19 ]

Fix two connection reaping bugs:

 (1) rxrpc_connection_expiry is in units of seconds, so
     rxrpc_disconnect_call() needs to multiply it by HZ when adding it to
     jiffies.

 (2) rxrpc_client_conn_reap_timeout() should set RXRPC_CLIENT_REAP_TIMER if
     local->kill_all_client_conns is clear, not if it is set (in which case
     we don't need the timer).  Without this, old client connections don't
     get cleaned up until the local endpoint is cleaned up.

Fixes: 5040011d073d ("rxrpc: Make the local endpoint hold a ref on a connected call")
Fixes: 0d6bf319bc5a ("rxrpc: Move the client conn cache management to the I/O thread")
