* dmi: check both the AC and ID flags at the same timeHEADmasterH. Peter Anvin2019-02-201-6/+11
| | | | | | | There is no reason to do the fairly complex flag-test sequence twice, when we might as well check for both flags at the same time. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* cpu_has_eflag(): mark output registers as earlyclobbersH. Peter Anvin2019-02-201-1/+1
| | | | | | | | | | | We assign values to the output registers before the input operand is used, so we have to use =&r to make sure the input operand isn't clobbered. Note: "ri" is correct; it cannot safely be a memory operand, because the stack pointer isn't where the compiler would expect it to be. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* cpu_has_eflag(): eliminate if the answer is already knownH. Peter Anvin2019-02-202-1/+20
| | | | | | | There is no need to test for a flag if the answer can be given at compile time. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* Fix all warnings, and better separate code that should not be mixedsyslinux-6.04-pre3H. Peter Anvin (Intel)2019-02-0723-96/+101
| | | | | | | | | Clean up a number of warnings in the tree. Refactor especially the core code so we don't end up building a bunch of BIOS-specific code for EFI, and general build cleanups. Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>
* com32.mk: removeH. Peter Anvin (Intel)2019-02-072-5/+5
| | | | | | | The file com32.mk is no longer used, as we don't use the traditional com32 format anymore (and haven't since version 4.xx). Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>
* install: don't install obsolete file com32.ldH. Peter Anvin (Intel)2019-02-061-1/+0
| | | | | | | | com32.ld has been obsolete for a long time, and has been removed now; don't install it either. Reported-by: Joakim Tjernlund <Joakim.Tjernlund@infinera.com> Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>
* libpng: update to 1.6.36H. Peter Anvin2019-02-0433-20888/+36638
| | | | | | Update libpng to version 1.6.36 due to errata in earlier versions. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* Reorganize and clean up a bunch of the x86 codeH. Peter Anvin2019-02-0430-596/+401
| | | | | | | We were doing a bunch of i386-specific things even on x86-64. Fix this, and merge x86 definitions where possible. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* com32: remove setjmp.S stub fileH. Peter Anvin2019-02-041-8/+0
| | | | | | Compile setjmp.S directly out of the $(ARCH) directory. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* libcc: move libgcc files into arch-specific directoriesH. Peter Anvin2019-02-0410-0/+0
| | | | | | | | We would compile these for for x86-64 even though they are i386-specific; the resulting code was meaningless but nevertheless included in the output. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* com32/lib: clean up unused filesH. Peter Anvin2019-02-046-613/+2
| | | | | | Clean up obsolete unused files; simplify setjmp.S stub Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* zlib: update to version 1.2.11H. Peter Anvin2019-01-2822-1280/+2308

* pxe: Fix recognition of keeppxe optionAdam Goldman2017-03-052-9/+11
| | | | | | | | | | | | | | | The preprocessor directive IS_PXELINUX is no longer valid. Submitted-by: Adam Goldman <adamg@pobox.com> Move "keeppxe" processing from com32/elflink/ldlinux/kernel.c:new_linux_kernel() to com32/lib/syslinux/load_linux.c:bios_boot_linux() using strstr() (not find_argument in original patch). Should also be processed by firmware->boot_linux() if not yet done. Signed-off-by: Gene Cumm <gene.cumm@gmail.com>
* chain.c32: update reactos= option for modern valueAdy2017-03-041-9/+3
| | | | | | | | | | | | | | | | | | | | Changed from "seg=0:0x8000:0x8100" to "seg=0x0F80" Reactos is "alpha", so the only version of Reactos that its devs support is the "latest" at each time. Older versions of Reactos are not relevant / supported by Reactos' devs. Submitted-By: Ady <ady-sf@hotmail.com> Old 2011-06-14 https://git.reactos.org/?p=reactos.git;a=blob;f=reactos/boot/freeldr/freeldr/include/arch/pc/x86common.h;hb=28e58e6d01892c1f2f0e1d323745e6463cb9e6c9 https://svn.reactos.org/svn/reactos/trunk/reactos/boot/freeldr/freeldr/include/arch/pc/x86common.h?revision=52226&view=markup New 2011-06-18 https://git.reactos.org/?p=reactos.git;a=blob;f=reactos/boot/freeldr/freeldr/include/arch/pc/x86common.h;hb=0eb6daaf66127de803d36d45a4eea29d30a7ca36 https://svn.reactos.org/svn/reactos/trunk/reactos/boot/freeldr/freeldr/include/arch/pc/x86common.h?revision=52346&view=markup Signed-off-by: Gene Cumm <gene.cumm@gmail.com>
* pxe_api.h: finish revert of 9acbffdGene 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>

* libupload: Use new TFTP OK status definitionGene Cumm2016-04-232-3/+3
| | | | | | | FTBFS: com32/hdt/hdt-dump.c:227:39: error: ‘TFTP_OK’ undeclared (first use in this function) Signed-off-by: Gene Cumm <gene.cumm@gmail.com>
* libupload: use url_set_ip()H. Peter Anvin2016-04-061-32/+18
| | | | | | | | We already have a core function for setting the IP address of an URL object based on network lookup or the server default. Export and use it instead of open-coding the equivalent logic in upload_tftp.c. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* pxe_dns: remove obsolete pxe_dns.c wrapperH. Peter Anvin2016-04-066-77/+4
| | | | | | | | | 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>
* libupload: don't error out because the tftp functions are unavailableH. Peter Anvin2016-04-062-16/+74
| | | | | | | | Provide weak stubs for the case where the tftp functions aren't available. This prevents link failures for the case of running on top of non-network cores. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* pxe_api.h: remove __weak from prototypesH. Peter Anvin2016-04-061-5/+5
| | | | | | | The prototypes themselves are not weak, and declaring them as such forces the core definitions, which should not be weak, as weak. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>

* Merge ↵Gene Cumm2016-01-192-9/+23
|\ | | | | | | | | | | | | 'git://github.com/Celelibi/syslinux.git/fix/bios/tail-call-stack-overflows' FIXME: this circumvents some of the issue but is not the cleanest and may reoccur.
| * ldlinux: fix stack overflow when running COM32 modulesSylvain Gault2015-10-132-9/+23
| | | | | | | | | | | | | | | | | | | | | | When a COM32 module exits, the functions never return and a new call to ldlinux_enter_command is made. This could fill the stack and overflow on some data present in memory. This patch use setjmp/longjmp to return to the main function and restart from there when a COM32 module exits.

* | com32: Adding 'exit' entry in chain.c32Erwan Velu2015-12-061-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is coming after some bad experience with gfxboot. GFXboot was padding unexpected options on the chain.c32 commande line. As a result, chain was confused and didn't provided the expected behavior. This patch is a workaround to enforce chain.c32 not considering anything on the command line after this keyword. Example: chain.c32 hd0 exit ...garbage...
* | com32: Handle broken modules.aliasErwan Velu2015-12-061-0/+8
| | | | | | | | | | | | | | | | When parsing the modules.alias, we shall report it as broken if we cannot find any valid line in it. This patch simply count the number of valid lines and report a missing modules.alias if no valid lines are found.
* | Makefile: Pass down the variable EFI_BUILDSylvain Gault2015-11-271-1/+1
| | | | | | | | | | | | | | | | This variable indicates whether or nor the files are compiled for EFI. The lack of it lead the Makefiles to forget to add some compilation options specific to EFI. Signed-off-by: Sylvain Gault <sylvain.gault@gmail.com>
* | ldlinux: Fix return pointer to local dataSylvain Gault2015-10-181-1/+1
|/ | | | | | | | | | | | | The command-line parsing used to return a pointer to a local array. The code used to work by chance, but now, gcc 5 is able to detect it and return a NULL pointer instead. The buffer is now marked static. This shouldn't be a problem as only one command line can be read at a time.

* mboot.c32: add ELF64 support for Multiboot1Alex2015-10-102-0/+124
| | | | | | | | | mboot.c32 lacks support for loading ELF64 binaries (supported by GRUB2, for example). This is a trivial patch to add such feature. [reflow some changes to fit ~80 columns; remove trailing whitespace - gene.cumm@gmail.com] Signed-off-by: Gene Cumm <gene.cumm@gmail.com>
* chrreplace: Don't skip the first characterJosh Triplett2015-09-281-1/+1

* com32/modules: Split build by architecture. Add dir.c32Gene Cumm2015-09-201-7/+16
| | | | | | | | | Certain modules directly make BIOS calls or call library functions that will not be ported from BIOS (like syslinux_shuffle_boot_rm()). It appears dir.c32 was long-forgotten for the Makefile Signed-off-by: Gene Cumm <gene.cumm@gmail.com>

* libupload: Reworking tftp support to use core functionsErwan Velu2015-09-041-147/+32
| | | | | | | | | | | | | | | 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.
* hdt: print tftp error number & message if dump failedErwan Velu2015-09-041-1/+2
| | | | | | | | | The current code was making a mistake by searching the -err element in the array as it was resulting into a negative value. The current patch does print the error number which could be useful but also retrieve the proper string to indicate the real error we encountered.
* hdt: Removing commas and plus signs from filenameErwan Velu2015-09-041-0/+6
| | | | | When uploading the dump file to a tftp server, removing the plus & comma sign from the filename could make the file easier to manipulate later.
* gpllib: Updating dmi codeErwan Velu2015-09-046-30/+67
| | | | | | | | This is a simple rebase of the current code against current dmidecode version. This is pretty lame copy/paste but as we don't have a libification of dmidecode, that does the job. This patch does improve mostly the cpu & ram reporting.
* hdt: Avoid false-positive single command detectionErwan Velu2015-09-041-2/+2
| | | | | | | | | | | | | | | Since commit 1697594b61f9a8f9d092996afc0e2c80bbb2a20a, some commands are said to be "nomodule" like "say". This patch was adding a check if the nomodule flag was set but didn't checked that the associated structure did exist leading to false positive detection. As a result, the commands were not executed meaning the CLI was unsuable since ... 3 years.... *shame* This commit simply avoid considering the nomodule flag if the structure is not allocated
* hdt: Fixing argv usage to avoid crashErwan Velu2015-09-041-5/+5
| | | | | | | argv shall be passed as a pointer to avoid a crash when running command like "dmi". Thanks genec for pointing this out.

| | | | | | | | | | | | The code was passing sizeof(const char *) - not the length of the string or the size of the buffer - as the length to strncmp(). These two cases don't need the length, so switch to strcmp.
