* pxe_api.h: finish revert of 9acbffdHEADmasterGene Cumm2016-11-271-3/+3
| | | | | | | | 9acbffd33b9200ffe37833463b4d4478e824295a caused more issues than it solves. There appears to be a bigger underlying issue that the __weak argument masks. Until the underlying issue is solved, we need __weak. Signed-off-by: Gene Cumm <gene.cumm@gmail.com>
* partial revert 9acbffdGene Cumm2016-11-271-2/+2
| | | | | | | | | Weaken 2 declarations. Seems to be the minimal amount for now. First exhibited issues with EFI but later also with BIOS beyond *pxelinux.0 when compiled with gcc-5.3.1 and gcc-6. Signed-off-by: Gene Cumm <gene.cumm@gmail.com>

* 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>
* pxe_api.h: remove __weak from prototypesH. Peter Anvin2016-04-061-5/+5

* Add filesystem UUID to SYSAPPEND for FATSerj Kalichev2014-03-131-0/+1
| | | | | | | | | | Filesystem UUID shows the partition we boot kernel from. The kernel parameter has format like FSUUID=DA1A-0B2E. The SYSAPPEND bit is 0x40000. Now the FAT only supports FSUUID.

| | | | | | | | | | | | | | | | | | | | | | | | commit 60dabb5b1d6d ("pxe: Make the SENDCOOKIES feature for HTTP worked again") introduced a regression for ldlinux because it references the 'SendCookies' symbol, which is only provided by PXELINUX. The regression was caused because the '__weak' tag was dropped from the declaration of SendCookies.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By registering memory scanners at runtime we can support multiple memory scanner functions, which helps us to isolate them and keep things modular, only registering them for specific platform/derivative combinations. This is preparation for adding a memory scanner that is specific to PXELINUX on bios and understands when the memory region occupied by the PXE stack can be reused.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The handover protocol is the preferred method of booting kernels on EFI because it allows workarounds for various firmware bugs to be contained in one place and applied irrespective of the chosen bootloader. Use it if available, but ensure that we fallback to the legacy boot method. Also, update the linux_header structure with recent changes made in the kernel source.

For example, say a user reports trouble with their PXE stack but doesn't have a development environment setup to turn on the debug code themselves. With this change you can simply request that they do, debug.c32 -e pxe_call unload_pxe open_file to enable the debug in those functions. By only turning on code in specific functions we reduce the chance of disrupting the buggy behaviour and improve the signal to noise ratio for print statements. To disable debug code use the -d flag, debug.c32 -d pxe_call To use this new feature simply do, if (syslinux_debug_enabled) { debug1(); debug2(); .... } from within the function you wish to add debug code. Note that this feature is not limited to print statements - you can put any code within the conditional, such as verifying a checksum or checking for memory leaks. The plan is to leave the dynamic debug code built in for all prereleases and to turn it off for final releases. People may still want to build with all dprintf() statements enabled, and so a new symbol, DYNAMIC_DEBUG, was introduced rather than repurposing the old DEBUG, DEBUG_STDIO and DEBUG_PORT symbols.
