* Dont bypass compiler driver for Dependency generation optionsKhem Raj2015-12-101-2/+2
| | | | | | | | | | | We can let compiler driver pass the right options to preprocessor after processing -Mxy options, right now its bypassing the gcc driver and handing them straight to cpp This also helps in other compilers processing these options correctly for their preprocessors consumption Signed-off-by: Khem Raj <raj.khem@gmail.com>
* Makefile: Always use -mno-red-zone for EFISylvain Gault2015-11-274-7/+12
| | | | | | | | This option is mandatory when compiling for EFI as some event handlers may interupt the running code and use the space just above the reserved stack space. Signed-off-by: Sylvain Gault <sylvain.gault@gmail.com>
* libupload: Reworking tftp support to use core functionsErwan Velu2015-09-041-2/+6
| | | | | | | | | | | | | | | The libupload was using the pxe_call() directly for doing the tftp uploading stuff. This was only working with pxelinux. Since we do have lpxelinux, the libupload should use the core functions to get rid of thoses direct PXE calls. This patch does - add a tftp_put() function which supports core functions. - implement the call from libupload making the code much more simplier As a result {l}pxelinux can upload data to a tftp server is a similar way. HDT is getting the benefit of such code.
* debug: Adding -DDEBUG_THREADErwan Velu2015-09-041-0/+1
| | | | | | | | | When debugging some syslinux code with debugging enabled, the threading code is so verbose that it completly slow down syslinux but also is so verbose that any other trace is invisible in the flood. This commit aims at requesting people to explicitly enable the threading logs by using -DDEBUG_THREAD.

* efi: Make the gnu-efi build scripts more portableMatt Fleming2014-01-081-2/+1
| | | | | | | | | | | | | Not all distributions point /bin/sh at /bin/bash, so remove some bashisms (pushd/popd) and require that build-gnu-efi.sh be run from the Syslinux object directory. Also, swap realpath(1) for readlink(1) because the former isn't available on Debian.

* efi: Make gnu-efi build scripts more robustMatt Fleming2013-12-111-1/+1
| | | | | | | | | | | | | | | Modify the scripts to check that they're called with the correct number of arguments and error out otherwise after printing some helpful info. This change also stops relying on passing arguments through environment variables and instead passes them explicitly to the scripts, which is definitely more robust, and handles the case where the scripts are invoked directly. Of course, now that the scripts can be invoked directly we need to regard any input as hostile and exit immediately on error. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
* efi: Add build scripts for gnu-efiMatt Fleming2013-12-101-15/+6
| | | | | | | | | | | Now that we have a gnu-efi git submodule we need some scripts to build and install it into architecture-specific build directories. This actually simplifies things a bit because we no longer need to account for the variations in distribution installation paths - we now control the paths.

* | mk: reinstate -mregparm for BIOSMatt Fleming2013-06-194-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | There's still a bunch of assembly code that assumes we're building our C objects with -mregparm=3. For example, the code to transition from 16-bit real-mode mode to 32-bit protected mode assumes this. Violating this assumption leads to various hangs, caused by garbage function arguments. Put back -mregparm into CFLAGS that was removed in commit 8789d2689564 ("mk/embedded.mk: Don't use -mregparm in core"). Signed-off-by: Matt Fleming <matt.fleming@intel.com>
* | ldlinux: use platform filename extensionMatt Fleming2013-05-162-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Users are starting to package all Syslinux versions on one boot medium and are running into problems because all versions of ldlinux have the same filename, ldlinux.c32. The version of ldlinux.c32 compiled for bios will not work with efi32 or efi64, and vice versa. What we need is a way for the Syslinux core to know exactly which filename to load. Use the following extensions for the corresponding platforms, .c32 - bios .e32 - efi32 .e64 - efi64 Now all ldlinux variants can be kept in the same directory without causing any conflicts.

* | efi: Add network supportsyslinux-6.00-pre5Matt Fleming2013-04-232-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add TCP and UDP support to the EFI firmware backend. This necessitated moving all tcp functions to a core_tcp_* prefix so that they could be implemented differently for BIOS+lwip and EFI. Unfortunately, the tcp_* prefix is already in use by the lwip code. To maintain symmetry, the UDP functions were also moved from net_core_* to core_udp_*. The net_core API was introduced in 5.x to allow the legacy PXE and lwip stacks to live side by side, and the intention was that net_core_init() would take a protocol argument to build a protocol-specific object. It turned out to be easier to call either udp or tcp functions directly because the semantics of read/write differ between protocols. Booting an IPv4 EFI PXE stack using tftp and http has been tested. There are a couple of TODO items left, o dns resolve code is missing o ftp hasn't been tested Signed-off-by: Matt Fleming <matt.fleming@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately commit 4eb06d95d882 ("mk: Add -fPIC for x86_64 to embedded.mk") left -mregparm enabled when compiling objects in core/, which means that when compiling for i386 those objects are compiled with a different ABI compared with everything else, leading to hangs when booting under 32-bit EFI. We should only enable -mregparm for code that absolutely requires it, such as dos/crt0.S which would need to be re-written to use another ABI. Signed-off-by: Matt Fleming <matt.fleming@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before modules were dynamically loaded the boundary between GPL and non-GPL code was implicit because of the separate link domains for each module. With dynamic modules we need an explicit whitelist of core symbols that non-GPL code can link against at runtime without needing to be re-licensed under the GPL. Mark such symbols with __export, so that it is explicitly clear which symbols in the core can be linked against by non-GPL code. Reduce the visibility of symbols in both the core and ldlinux.c32 with -fvisibility=hidden. __export changes the visibility to 'default'. Signed-off-by: Matt Fleming <matt.fleming@intel.com>

Move the implementation of 'struct disk_private' into more suitable locations and use a void * for the 'private' member of struct disk.
