| | | | | | | | | Light userdata don't have individual metatables, thus they aren't suitable for type checking. Also, a200ad6d replaced relying on reused memory (from luaL_checkstring) with writing to uninitialized pointers; copy the filename instead into freshly allocated memory.

| | | | | | | | Start with the src/Makefile in Syslinux before importing Lua 5.2.2. Refresh the core Lua object list based on the original Makefile. Add the new builtin library objects. Temporarily remove the Syslinux extension library objects, as they need adjustments for the new API.

* com32sys_t inreg shall be zeroified prior intcallErwan Velu2014-01-221-1/+2
| | | | | | | | | | | As per commit f775e740a3a817a4ff5ba26bea99dbfd735456b3, inreg parameters of intcall() shall be zeroified. Having unclean inreg could trigger bad behaviors on some hosts. This patch is about adding memset() calls prior any intcall() : - some intcall didn't had any memset at all - some successive intcall() calls didn't memset inreg in between calls

| | | | | | | | | | | | | | | | | | | | | | | | | | | names in table entries. It also misses a number DMI sub-tables. This patch, cleans up the DMI table structure using Lua's nested table structure and adds all missing DMI sub-tables. If a DMI sub-table is not supported by the hardware (not filled), then the corresponding sub-table will not be generated. This helps to make the table structure cleaner and reflects the actual DMI information. Signed-off-by: Hung-chi Lihn <hlihn@google.com> Signed-off-by: Erwan Velu <erwanaliasr1@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | reboot() to Lua.c32. This allows the Lua script to query the config file name and the ipappend strings (pxelinux only), as well as to perform reboot (warm and cold) to the system. In Lua.c32, the extension will be used as the following: 1. syslinux.config_file() will return the config file string. 2. syslinux.ipappend_strs() will return a table of IPAPPEND strings with numerical indices. 3. syslinux.reboot() will perform cold reboot, while syslinux.reboot(1) will perform warm reboot.

| | * The current Lua.c32 does not enable io.read() due to some missing library ↵Hung-chi Lihn2012-09-221-11/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | functions. However, this strongly limits the Lua script from getting user inputs and reading files (even in pxelinux via TFTP). This patch enables io.read() in Lua.c32 with some restrictions: 1. the io.read("*line") is fully supported. 2. the io.read("*number") is not supported due to the missing buffering in underlying file I/Os. However, the user can read a line using io.read() and convert the string to numbers using the built in pattern matching and number conversion features. 3. io.read(bytes) is supported. However, io.read(0) will not be a valid test for EOF due to the missing I/O buffering. io.read() will return nil if EOF is encountered. This offers an alternative way to handle EOF.

* | | Add per-firmware object directory supportMatt Fleming2012-10-161-2/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we have multiple firmware backends it no longer makes sense to write object files to the same directory as their source. A better solution is to write the object files to a per-firmware directory under a top-level object directory. The top-level object directory can be specified on the command-line with the O= variable, e.g. make O=/tmp/obj. If no top-level object directory is specified an 'obj' directory is created in the top-level of the Syslinux source repository. All the existing make targets continue to work as before, however now they apply to all firmware backends, e.g. 'make installer' will build the BIOS, 32-bit EFI and 64-bit EFI installers and place them under $(OBJ)/bios, $(OBJ)/efi32 and $(OBJ)/efi64 respectively. Note unlike every other bit of Syslinux, the gpxe objects are still kept in the src directory, e.g. gpxe/src, since gpxe is only required by the BIOS backend. It is possible to specify a make target for a specific firmware or list of firmware with the following syntax, make [firmware[,firmware]] [target[,target]] To clean the object directory for just the BIOS firmware type, 'make bios clean' To build both the 32-bit and 64-bit EFI installers type, 'make efi32 efi64 installer' Since the Syslinux make infrastructure is now more complex a new file doc/building.txt has been created to explain how to build Syslinux. The top-level Makefile now exports some make variables for use in module Makefiles, - topdir - the top-level source directory of the Syslinux repository, e.g. /usr/src/syslinux - objdir - the top-level object directory for the firmware backend currently being built, e.g. /obj/syslinux/bios - SRC - the source directory in the Syslinux repository for the module currently being built, e.g. /usr/src/syslinux/com32/libupload - OBJ - the object directory for the module currently being built, e.g. /obj/syslinux/bios/com32/libupload Since we're rewriting the Makefile infrastructure anyway it seemed like a good idea to add parallel support. By writing subdirectories as prequisites for make targets the objects in those subdirectories can be built in parallel. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
