When call isohybrid with option '-u', it overflows on a 32 bits host. It seeks to 512 bytes before the end of the image to install gpt header. If the size of image is larger than LONG_MAX, it overflows fseek() and cause error: isohybrid: image-x86-64-20140505110100.iso: seek error - 8: Invalid argument Repla...

Hello all, Past few days I was working on porting the isohybrid perl script to c. (-> https://fedorahosted.org/fedora-engineering-services/ticket/15) The first patch towards the same is attached with this mail. And the same could also be accessed from: http://pjp.dgplug.org/tools/syslinux-3.86-isohybrid.patch I would really appreciate it if somebody could...

Dear list, I have been trying to debug a build failure for a while in the utils directory on isohybrid which seems to be distro specific. On Fedora 17 64bit the build completes without problems, but under both Ubuntu 32/64bit 11.10 and 12.04 I get the following: tim at oxygen:/usr/src/git/syslinux/utils$ make gcc -O2 -luuid -o isohybrid isohybrid.o isohdpfx.o isohybrid.o: In function `initialise_...

Hi, following will be 6 patch proposals for isohybrid.c 1: Encode GPT partition names as UTF-16LE 2: Correct blocking factor in APM partition block counts 3: Correct end block address of first GPT partition 4: Write GPT backup to the very end of the image 5: Change all fseek(3) to fseeko(3) 6: Introduce option --mbr and make isohybrid.c compilab...

Hi, at [Tails] we're in the process of shipping hybrid ISO images by default again. We're using `isohybrid -h 255 -s 63' to do that (thanks to the advice we got on this mailing-list a few months ago!). And then, we've discovered that sometimes, isohybrid produces ISO images whose size is not a multiple of 2048 bytes. Who cares? ... may you ask. Well, apparently, VirtualBox does: it refuses to...

Hi, > All the "isohybrid.exe" I know of are based on the Perl variant. I just got one from http://www.filewatcher.com/m/isohybrid.exe.39568-0.html Its strings seem not to stem from isohybrid.pl. Digging in slitaz source brought a shell script (that would be variant #5 then): http://hg.slitaz.org/wok/file/313b38...

...(bytes_per_sector). The known ISO production programs comply to this condition. (Theoretically there could be other block sizes between 512 byte and 64 KiB. But 2048 is the address granularity of optical media and so no other block sizes have been seen yet.) > 2_ The resulting size of the isohybrid image shall be a multiple of > 2048 bytes. > 3_ The resulting partition size should better match the end of a > complete cylinder (the latter is the value to be calculated and > optimized). Would #3 allow that the ISO image file size is larger than the partition size ? Like the resu...
