This is a revised version of the two series previously posted here: https://www.redhat.com/archives/libguestfs/2019-January/msg00137.html https://www.redhat.com/archives/libguestfs/2019-January/msg00139.html There have been many smaller changes but the highlights are: - Using SECTOR_SIZE instead of hard-coding 512 everywhere. - Additional safety checks that the EBR chain doesn't jump

An evolution of the patch I posted yesterday to qemu-devel (https://www.mail-archive.com/qemu-devel@nongnu.org/msg588920.html) which (a) works and (b) has a test. Rich.

I think this addresses everything in Eric's v2 review. Note that the first patch is best viewed using ‘-w’ to ignore whitespaces changes. Rich.

1) code split and move Iterator related functionality is yanked from chain.c and moved to iterator.{c,h}. Both are moved to com32/chain and this way chain.c is ready for further splitting. Alternatively, partiter could be moved to com32/lib at any time in the future. It's potentially useful for other modules (e.g. if someone wanted to code partition dumper or editor). 2) Iterator updates

...ohybrid MBR, then the isohybrid MBR code will see a ridiculously low start address of the partition and thus load the wrong blocks from disk instead of the content of isolinux.bin. The partok isohybrid MBR would have to look up the extended partition in the disk MBR and then hop along the chain of EBRs until it finds itself by some magic number. Currently this looks quite hopeless for 432 bytes of code. One could throw out the noop commands which reserve space for the fake Apple Partition Map block 0 of isohybrid --mac. One could shorten the error message. But i doubt that would suffice. Have...

The first problem is that if you make a builder or .rxml file it always displays as xml in a browser. declare! it and the browser gives and error and if you change rxml to rhtml then it thinks you should be making erb. SO quetion #1 is how do I make builder files render in the browser as html. The next thing that I want to be able to do is be able to render parcials or call other files of other

1) At the end of main, there's attempt to free cur_part->record, which rarely comes from malloc. Only valid case is if gpt handover was performed and chaining was not successful (cur_part->record is overwritten with gpt specifc handover record). Freeing the handover area has been adjusted. 2) If our current iterator is ebr, parent wouldn't be freed at the end of main. Added generic

This implements support for MBR logical partitions in nbdkit-partition-filter, complementing existing support in the partitioning plugin. Rich.

1) public index in gpt iterator should not skip empty partitions, e.g. if we have 1st and 3rd gpt entry used, we expect the numbers to be 1 and 3, not 1 and 2 (similary to how linux sees it e.g. /dev/sda1 and /dev/sda3). It's analogous to index / mbr_index fix. 2) free(ebr_part); in mbr iterator was not reachable. ebr iterator takes care of freeing itself and its parent. 3) in ebr iterator,

A fairly straightforward replacement, but note that we must rename all variables called ‘regions’ as something else (eg. ‘rs’) because -Wshadow warns about them (which is surprising to me since I thought this warning only applied to local vs global variable, not local variable vs global typedef). Also I got rid of the get_regions accessor method, replacing it everywhere with direct use of

This patch introduces extra functionality to chain.c, mainly with reference to BPB adjustments, but not only that. It expects 3 small patches I sent earlier (they are included for easy reference, patches 1-3/4). The changes introduced are: 1) file and boot sector use separate options to control load address and jump address (if applicable). Options are as described below: *

Yes, these are my thoughts as well. I think the jump from GRUB to the isohybrid code on the logical partition is working fine, but when the isohybrid code is trying to jump to
