There are a couple of issues regarding egd support in OpenSSH. 1) SIGPIPE is not ignored for the master listener daemon. I put the signal() call early on since it needs to be before get_random_bytes() is called but it could also be placed in the EGD version of get_random_bytes(). For some reason, with prngd I am getting SIGPIPE even though the prngd processes is not dying. get_random_bytes() also needs to check for EPIPE and reconnect to the daemon if it gets that. 2) If there...

The attached patch adds an option (off by default to preserve current behavior) to set a timeout on the select() statement that waits for input in clientloop.c. This fixes a timeout issue for me (explained below) and probably also fixes the timeouts mentioned in last month's thread "Idle time out". The patch is also available by http from:

Based on net-next. This patch exports port->port_no port->port_id in the end of IFA_INFO_DATA.

All, Please review the patches backported to 1.4 from mainline. Sunil

With the ATI bug I was hitting earlier fixed, only my btrfs partition continues to show high cpu usage for some operations. Rsync, git pull, git checkout and svn up are typicall operations which trigger the high cpu usage. As an example, this perf report is from using git checkout to change to a new branch; the change needed to checkout 208 files out of about 1600 total files. du(1) reports
