* pxe_dns: remove obsolete pxe_dns.c wrapperH. Peter Anvin2016-04-061-1/+1
| | | | | | | | | We used to need a wrapper around the core function dns_resolv() to implement pxe_dns(), because the former function required its argument to live in low memory. This is no longer the case and hasn't been for a while, so remove this unnecessary level of indirection. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>

A target depending on another target marked .PHONY is always rebuilt, thus forcing all the .o files to be rebuilt everytime.

* | efi/x86_64: leave long mode properlyThomas Letan2015-09-061-20/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Syslinux 6.03 (efi64) fails to boot a 32-bit kernel. The way Syslinux leaves long mode in kernel_jump assembly routine does not follow AMD64 specifications. More precisely: 1. After setting a new GADT, `cs` has to be refresh by doing a long jump, but it is not 2. Other segments have to be updated, but they are not 3. Disabling paging has to be done before disabling long mode, but the implementation does the opposite In most cases, a computer that tries to execute the kernel_jump routine reboot (it can also hangs). This patch fixes the kernel_jump routine. Signed-off-by: Thomas Letan <thomas.letan@ssi.gouv.fr> Tested-by: Patrick Masotta <masottaus@yahoo.com> Tested-by: Celelibi <celelibi@gmail.com>

* efi: Tag __syslinux_adv* with __exportMatt Fleming2014-06-241-2/+2
| | | | | | | | | | | | | | | | | | | | | commit 415d571 ("adv: Remove double defintion") introduced a regression for the EFI boot loader. The commit is correct, but should have tagged the __syslinux_adv_ptr and __syslinux_adv_size data objects in the EFI core as __export. This change is required because symbols in the EFI code are not global by default, and so, when ldlinux.{e32,e64} tries to bind to the adv symbols it fails. The following demonstrates the ELF symbol changes, Before: 659: 0000000000034f40 8 OBJECT LOCAL DEFAULT 16 __syslinux_adv_ptr After: 957: 0000000000036fe0 8 OBJECT GLOBAL DEFAULT 16 __syslinux_adv_ptr Signed-off-by: Matt Fleming <matt.fleming@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PE headers code_sz and image_sz indicate more or less, the size of the file and the size of the in-memory image. They are now given the right value. In the ELF format, only the program headers are reliable to determine the actually needed part of the file and the in-memory size. The .bss section should always be marked as NOLOAD for ld since its content shouldn't be included into the binary file. Signed-off-by: Sylvain Gault <sylvain.gault@gmail.com> Signed-off-by: H.

| | | | | | | | | | | | | | | | | | | | | | | | OVMF and probably other UEFI implementation refuse a file with a relocation entry inside the headers. And since the dummy relocation wasn't used at all, better remove it. Moreover, the field base_relocation_table wasn't initialized properly, leading to unpredictable bugs.

* | efi: Location, size and alignment of .text sectionSylvain Gault2014-02-141-19/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | In the generated PE file, the section header for the .text section used to address more than the whole file. Starting at offset 0 (before the end of the headers) is illegal and is rejected by OVMF. Giving a size greater than the actual file size is also illegal and rejected. Moreover, the body of the PE file have to be aligned to at least 512 bytes. Hence, .text need to be aligned as well. Signed-off-by: Sylvain Gault <sylvain.gault@gmail.com> Signed-off-by: H.
