* | libinstaller: introduce syslxrw libraryPaulo Alcantara2015-11-1011-67/+113
| | | | | | | | | | | | | | | | Due to size constraints on DOS systems, do not include whole syslxcom into DOS-based installer for using xpread() and xpwrite() functions, instead make them part of another separate library and include it only. Signed-off-by: Paulo Alcantara <pcacjr@zytor.com>

* | 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.

* | 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.

* | libinstaller: Explicit failure if path isn't writableErwan Velu2015-09-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per bug #4, we should report a clear failure if the target path is not writable. The current code was catching the fact the file was not writable but it didn't wrote an explicit message and even more confusing, was trying to process the file descriptor leading to a creepy "Bad file descriptor" error message. This patch does return EACCES to avoid process the file description. It also print an explicit message saying a particular file isn't writable which generates a fatal error. A typical output looks like : [root@host]: extlinux --once=plop /boot /boot is device /dev/sda Cannot open file '/boot/ldlinux.sys' in read/write mode ! Fatal error, exiting.

* | 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>
* | libupload: Reworking tftp support to use core functionsErwan Velu2015-09-045-150/+220
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* | 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.

| | | | | | | | | | | | | | | | | | 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 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.

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

| | | | | | | | | | | | | | | | | | | | | | 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.
