* libupload: use url_set_ip()H. Peter Anvin2016-04-062-4/+17
| | | | | | | | 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 Anvin2016-04-063-13/+3
| | | | | | | | | 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 Anvin2016-04-061-1/+3
| | | | | | | | 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>

* syslinux.ld: align the initial heap to 4K rather than 64KH. Peter Anvin2016-03-011-2/+2

* core/layout.inc: we don't need the _lma symbols except in one caseH. Peter Anvin2016-02-111-1/+3
| | | | | | | | | We don't need any of the _lma symbols, except for the one associated with .pm_code. Don't export them unconditionally in SECINFO, because that makes the linker request them as unknown symbols in the dynamic section. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| * core: Fix stack overflow when reloading configSylvain Gault2015-10-131-1/+57
| | | | | | | | | | | | | | | | | | | | | | The behavior when running a "CONFIG" command line is to reload ldlinux.c32 with the new file as argument. This call never return. In order to avoid stacking up the calls to start_ldlinux, this patch introduce a setjmp/longjmp to return to the first call to start_ldlinux, thus freeing all the stack space.

* | | btrfs: Fix logical to physical block address mappingPaulo Alcantara2015-12-272-16/+35
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current btrfs support did not handled multiple stripes stored in chunk items, hence skipping the physical addresses that were needed to do the mapping. Besides, the chunk tree may contain DEV_ITEM keys which store information on all of the underlying block devices, so we must skip them instead of finishing lookup. The bug was reproduced with btrfs-progs v4.2.2. Cc: Gene Cumm <gene.cumm@gmail.com> Cc: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Paulo Alcantara <pcacjr@zytor.com> --- v1 -> v2: * Do not set ignore_key multiple times.

* | bios: Don't try to guess the sections alignmentSylvain Gault2015-11-082-102/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For the compression / decompression to succeed, the sections layout must be the same between the virtual memory and load memory. The section alignment was kept in sync by introducing aligment that should be greater or equal to the actual section alignment. This patch compute the load memory addresses of the sections so that the layout is the same as the virtual memory addresses.

* core/pxe: Allow DHCP option 54 Server IdentifierGene Cumm2015-10-081-2/+6
| | | | | | | | | | | Apparently some servers don't bother setting siaddr when pointing to itself for TFTP. Re-allow 54 but always set IPInfo.serverip from siaddr/dhcp->sip in packet #3 (PXEReply/proxyDHCP). Always set from siaddr if good in case parsing after-DHCP options.

* core: readd gPXE/iPXE support for HTTP on pxelinux.0Gene Cumm2015-09-273-81/+108
| | | | | | | | | | | When adding lwIP functionality, the gPXE/iPXE callback was broken. This prevented pxelinux.0 from calling gPXE/iPXE for HTTP and FTP URLs. Re-add for pxelinux.0 and add code to find file size. Move to core/legacynet/core.c to access packet_buf and leave a dummy function for lpxelinux.0. Signed-off-by: Gene Cumm <gene.cumm@gmail.com>

* pxe/dhcp_option: Don't parse DHCP option 54 Server IdentifierGene Cumm2015-09-121-1/+0
| | | | | | | Server Identifier is NEVER the next server where Syslinux was loaded from. BOOTP field siaddr, BOOTP field sname and DHCP option 66 TFTP server name may contain this information. For now, just use siaddr.
* libupload: Reworking tftp support to use core functionsErwan Velu2015-09-043-1/+182
| | | | | | | | | | | | | | | 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.
* tftp: Report server IP address on debug messageErwan Velu2015-09-041-1/+10
| | | | | When debugging, it is very useful to get the ip adress of the server that reponsded to that packet.
* debug: Adding -DDEBUG_THREADErwan Velu2015-09-041-0/+4
| | | | | | | | | 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.
* core: dprintf on malloc/free if -DDEBUG_MALLOCErwan Velu2015-09-022-0/+6
| | | | | | | | | | | When dynamic debug is engaged, the output is pretty flooded by malloc/free messages while you are looking at other traces. As devel.mk have a DEBUG_MALLOC option, it seems pretty logical to enable the malloc/free dprintf() only if this option is engaged. That patch make the dynamic debug output less floody while letting the choice to get the malloc/free dprintf() messages.

* build: sort sources to build in a more deterministic wayPhilippe Coval2015-01-051-5/+5
| | | | | | | | | | | | | | | | | It has been observed that binaries contents are depending on the order of linked objects. This order is caused by GNU make's wildcard function and the position of sources on filesystem. This change tries to prevent this kind of randomness. Also consider building using -j1 flag to make it even more reproductible.
