* libstand: make more use of the howmany() macro when available.pfg2016-04-261-1/+1

* A new implementation of the loader block cacheallanjude2016-04-188-103/+189
| | | | | | | | | | | | | | | | | 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.

It turns out they aren't referenced anywhere, but their presence prevents using sys/endian.h in libstand code. These days, sys/endian.h provides much better support for such things, using compiler builtins and inline functions (and creating connections between libstand code and header files from sys/ would not be breaking new ground).

* Reduce libstand Makefile duplicationemaste2016-01-011-3/+4
| | | | | | | | | | | | | | | | libstand is built in three places (lib/libstand, sys/boot/libstand32, and sys/boot/userboot/libstand). Reduce Makefile duplication by .including libstand/Makefile from sys/boot/libstand32/Makefile. sys/boot/userboot/libstand/Makefile will be addressed later, as it contains additional differences yet to be handled. This change also switches libstand32 to use the new uuid_from_string and uuid_to_string, which was not included in r292473.

* Allow dhcp/bootp server-provided values to be overriden from environmentian2015-12-221-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | variables in loader(8) and other libstand applications. Sometimes a dhcp server provides incorrect information along with the IP address. It would be useful to have a way to override this with locally-supplied information, such as command line parameters passed from a prior-stage bootloader. This change allows pre-existing env vars to take precedence over values delivered by the dhcp or bootp server. The bootp/dhcp code in libstand automatically creates environment variables from the data provided by the server (dhcp.root-path, dhcp.domain-name, etc). It also transcribes the values to some global variables such as 'rootpath' and 'hostname'. This change does two things: When adding dhcp.* vars to the environment, don't replace existing vars/values. When setting the global vars rootpath and hostname, use the dhcp.root-path and dhcp.host-name env var values if they exist. This allows the platform-specific part of loader(8) to obtain override values in some platform-specific way and store them in the environment before opening the network device. The set of values that can be overriden is currently limited to just string options. The values that are delivered as binary data are things that probably shouldn't be overridden (IP, netmask, gateway, etc). The original patch this evolved from was submitted by martymac@ PR: 202098 Differential Revision: https://reviews.freebsd.org/D4559
* Create libstand version of uuid_from_string and uuid_to_string. Theimp2015-12-193-1/+244
| | | | | | | | | | | normal libc versions of these functions use asprintf and sscanf, both of which aren't available in the libstand world. It's easier to rewrite these than to try to claw those functions into libstand. Also include uuid_create_nil, since it's safe to include. These were written from scratch, except for bits of comments that I got from the libc version, which are acknowledged in the source. Differential Revision: https://reviews.freebsd.org/D4540
* pxeboot: make the tftp loader use the option root-path directivebapt2015-12-161-3/+17
| | | | | | | | | | | | | | | | | | | | pxeboot in tftp loader mode (when built with LOADER_TFTP_SUPPORT) now prefix all the path to open with the path obtained via the option 'root-path' directive. This allows to be able to use the traditional content /boot out of box. Meaning it now works pretty much like all other loaders. It simplifies hosting hosting multiple version of FreeBSD on a tftp server. As a consequence, pxeboot does not look anymore for a pxeboot.4th (which was never provided) Note: that pxeboot in tftp loader mode is not built by default.
