* lua: Update to 5.4.4Warner Losh2023-02-081-0/+73
| | | | | | | | | | | | | | | Merge commit '755d9301ca89f02956fd17858b9d4d821ab5c972' from the vendor branch. This updates us from lua 5.4.2 to 5.4.4. In addition, it switches around how we flavor liblua for the boot loader and flua. This is done to reduce diffs with upstream and make it easier to import new versions (the current method has too many conflicts to resolve by hand): we include luaconf.local.h from luaconf.h (the only change to this file is now that #include at the end). We then define what we need to: for flua (which does very little) and one for stand (which creates the new FLOAT type out of int64). Sponsored by: Netflix
* lua: reduce diffs between luaconf.h copiesEd Maste2023-01-261-3/+4
| | | | | | | | | | | | | Upstream luaconf.h is contrib/lua/src/luaconf.h.dist, while userland lua and loader lua have copies in lib/liblua/luaconf.h and stand/liblua/luaconf.h. Adjust whitespace, VCS tags, etc. to match upstream's version, for ease of comparison. Reviewed By: imp Sponsored By: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D38206

* EFI secure boot VECTX related changesEric van Gyzen2021-04-301-3/+2
| | | | | | | | | | | | | | When VECTX is enabled as a kernel option and non-EFI loaders are built, many reads will fail due to the mis-match of whether LOADER_VERIEXEC_VECTX or not in readin.h. Source that includes bootstrap.h must ensure the kernel option agrees with the compile time CFLAGS in the various make related files.

* stand: liblua: add a pager moduleKyle Evans2020-12-123-1/+91
| | | | | | | | | | | | | | | This is nearly a 1:1 mapping of the pager API from libsa. The only real difference is that pager.output() will accept any number of arguments and coerce all of them to strings for output using luaL_tolstring (i.e. the __tostring metamethod will be used). The only consumer planned at this time is the upcoming "show-module-options" implementation. MFC after: 1 week Notes: svn path=/head/; revision=368591

* veloader use vectx API for kernel and modulesSimon J. Gerraty2020-03-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vectx API, computes the hash for verifying a file as it is read. This avoids the overhead of reading files twice - once to verify, then again to load. For doing an install via loader, avoiding the need to rewind large files is critical. This API is only used for modules, kernel and mdimage as these are the biggest files read by the loader. The reduction in boot time depends on how expensive the I/O is on any given platform. On a fast VM we see 6% improvement. For install via loader the first file to be verified is likely to be the kernel, so some of the prep work (finding manifest etc) done by verify_file() needs to be factored so it can be reused for vectx_open(). For missing or unrecognized fingerprint entries, we fail in vectx_open() unless verifying is disabled. Otherwise fingerprint check happens in vectx_close() and since this API is only used for files which must be verified (VE_MUST) we panic if we get an incorrect hash.

* stand: liblua: drop default buffer size to 128Kyle Evans2019-12-121-5/+1
| | | | | | | | | | | | | | | | Lua allocates LUAL_BUFFERSIZE buffers on the stack for various string functions (string.format, string.gsub) -- this works out to be somewhat significant and not necessary, based on how we use string operations. Dropping it risks having to allocate per call to format/gsub, but this is not the case for our usage. This simply stops allocating 8K buffers on the stack when luaL_Buffer is used.

* Add flua to the base system, install to /usr/libexecKyle Evans2019-11-183-376/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever extensions we need for base system operations. We currently support a subset of lfs and lposix that are used in the rewrite of makesyscall.sh into lua, added in r354786. flua is intentionally written such that one can install standard lua and some set of lua modules from ports and achieve the same effect. linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added in. This is similar to what we do in stand/. linit.c has been renamed to make it clear that this has flua-specific bits. luaconf has been slightly obfuscated to make extensions more difficult. Part of the problem is that flua is already hard enough to use as a bootstrap tool because it's not in PATH- attempting to do extension loading would require a special bootstrap version of flua with paths changed to protect the innocent. src.lua.mk has been added to make it easy for in-tree stuff to find flua, whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.

* liblua: add loader.lua_pathKyle Evans2019-11-021-0/+2
| | | | | | | | | | | | As described previously, loader.lua_path is absolute path where scripts are installed. A future commit will use this to build paths for dofile in try_include, rather than the current pcall/require setup that makes it more difficult to coordinate loader aborts from local.lua -- we do not need the flexibility of require(), and local.lua is in-fact not a 'module-like' file as we will not be referencing anything from it.

Knock this down to being formally defined (and overridable) in exactly one spot, defs.mk, and spread the knowledge to loaders and liblua alike.

* Create new EINTEGRITY error with message "Integrity check failed".Kirk McKusick2019-01-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | An integrity check such as a check-hash or a cross-correlation failed. The integrity error falls between EINVAL that identifies errors in parameters to a system call and EIO that identifies errors with the underlying storage media. EINTEGRITY is typically raised by intermediate kernel layers such as a filesystem or an in-kernel GEOM subsystem when they detect inconsistencies. Uses include allowing the mount(8) command to return a different exit value to automate the running of fsck(8) during a system boot. These changes make no use of the new error, they just add it. Later commits will be made for the use of the new error number and it will be added to additional manual pages as appropriate.

* liblua: Add loader.interpretKyle Evans2018-03-031-0/+20
| | | | | | | | | | | | | | This allows lua to pass back a command string to be executed as if it were typed at the loader prompt- loader tries to execute the string first as pure lua, then parses it and gives lua a chance to intercept before it tries to execute it itself.

* Add Lua as a scripting langauge to /boot/loaderWarner Losh2018-02-129-0/+1502
liblua glues the lua run time into the boot loader. It implements all the runtime routines that lua expects. In addition, it has a few standard 'C' headers that nueter various aspects of the LUA build that are too specific to lua to be in libsa. Many refinements from the original code to improve implementation and the number of included lua libraries. Use int64_t for lua_Number. Have "/boot/lua" be the default module path. Numerous cleanups from the original GSoC project, including hacking libsa to allow lua to be built with only one change outside luaconf.h. Add the final bit of lua glue to bring in liblua and plug into the multiple interpreter framework, previously committed. Add LOADER_LUA option, currently off by default. Presently, this is an experimental option. One must opt-in to using this by defining WITH_LOADER_LUA and WITHOUT_FORTH. It's been lightly tested, so keep a backup copy of your old loader handy. The menu code, coming in the next commit, hasn't been exhaustively tested. A LUA boot loader is 60k larger than a FORTH one, which is 80k larger than a no-interpreter one. Subtle changes in size may tip things past some subtle limit (the binary is ~430k now when built with LUA). A future version may offer coexistance. Bump FreeBSD version to 1200058 to mark the milestone. Pedro Souza's 2014 Summer of Code project. Rui Paulo, Pedro Arthur, Zakary Nafziger and Wojciech A. Koszek also contributed.
