dosfs support in libstand is broken since r298230

2016-12-30T19:06:29Z

Apparently the libstand dosfs optimization is a bit too optimistic and did introduce possible memory corruption. This patch is backing out the bad part and since this results in dosfs reading full blocks now, we can also remove extra offset argument from dv_strategy callback. The analysis of the issue and the backout patch is provided by Mikhail Kupchik.

lsdev device name section headers should be printed by dv_print callback.

2016-11-19T08:54:21Z

lsdev command does walk over devsw list, prints list element name and will use dv_print() callback to print the device list. Unfortunately this approach will add unneeded noise when there are no particular devices detected. To remove "empty" device section headers, the dv_print() callback should print the header instead. In addition, fixed dv_print callback for md module. Reviewed by: imp Approved by: imp (mentor) Differential Revision: https://reviews.freebsd.org/D8551

Loader paged/pageable data is not always paged.

2016-11-08T06:50:18Z

This change does modify devsw dv_print() to return the int value, enabling walkers to interrupt the walk on non zero value from dv_print(). This will allow the pager_print actually to stop displaying data on user input, and additionally pager is used in various *dev_print callbacks, where it was missing. For test, lsdev [-v] command should display data by screenfuls and should stop when the key 'q' is pressed on pager prompt.

Fix several instances where the boot loader ignored pager_output

2016-05-18T05:59:05Z

return value when it could return 1 (indicating we should stop). Fix a few instances of pager_open() / pager_close() not being called. Actually use these routines for the environment variable printing code I just committed.

A new implementation of the loader block cache

2016-04-18T23:09:22Z

The block cache implementation in loader has proven to be almost useless, and in worst case even slowing down the disk reads due to insufficient cache size and extra memory copy. Also the current cache implementation does not cache reads from CDs, or work with zfs built on top of multiple disks. Instead of an LRU, this code uses a simple hash (O(1) read from cache), and instead of a single global cache, a separate cache per block device. The cache also implements limited read-ahead to increase performance. To simplify read ahead management, the read ahead will not wrap over bcache end, so in worst case, single block physical read will be performed to fill the last block in bcache. Booting from a virtual CD over IPMI: 0ms latency, before: 27 second, after: 7 seconds 60ms latency, before: over 12 minutes, after: under 5 minutes.
