[Bug 1892290] Re: PXE load Focal initrd.img-5.4.0-42-generic always timeout
This bug was fixed in the package grub2 - 2.06-2ubuntu3 --- grub2 (2.06-2ubuntu3) jammy; urgency=medium * Cherry-pick the missing hunk back that changes parameter loading in grub-core/loader/i386/linux.c, this should fix booting on BIOS systems. * Fix the fallback for kernel addresses on amd64 EFI, if the kernel could not be allocated at the preferred address, reset errno such that if the 2nd allocation succeeds, we do not fail erroneously. -- Julian Andres Klode Mon, 13 Dec 2021 14:27:53 +0100 ** Changed in: grub2 (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892290 Title: PXE load Focal initrd.img-5.4.0-42-generic always timeout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1892290/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1892290] Re: PXE load Focal initrd.img-5.4.0-42-generic always timeout
hi @xinliang - thanks for raising this bug, and for the info. I've got my way through to a grub build (I'm going to append some extra notes to your instructions) but, I'm unclear about where the: $ sudo apt install ./*.deb is supposed to be applied - are you doing this on your pxe/tftp server? Or does this need to be in the image that is being netbooted? (or both?) If it's going on the pxe/tftp server, what files is it providing/replacing to resolve the bug (ie is it updating a bootx64.efi image)? As promised - a little extra detail on the build notes: $ git clone -b applied/ubuntu/focal-updates https://git.launchpad.net/ubuntu/+source/grub2 $ cd grub2 $ git cherry-pick a6838bbc6726ad624bd2b94991f690b8e9d23c69 # this will throw an error $ git remote add upstream https://git.savannah.gnu.org/git/grub.git $ git fetch upstream $ git cherry-pick a6838bbc6726ad624bd2b94991f690b8e9d23c69 $ dpkg-buildpackage -rfakeroot -b -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892290 Title: PXE load Focal initrd.img-5.4.0-42-generic always timeout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1892290/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Similar bug: https://bugzilla.redhat.com/show_bug.cgi?id=1869987 I've tried boot by cmdline, looks the same issue. grub> linux vmlinuz-5.4.0-47-generic grub> echo $? 0 grub> initrd initrd.img-5.4.0-47-generic error: timeout reading `initrd.img-5.4.0-47-generic'. grub> echo $? 28 It looks like it is caused by Commit 781b3e5efc3 (tftp: Do not use priority queue) . And bellow upstream commit can fix it. commit a6838bbc6726ad624bd2b94991f690b8e9d23c69 Author: Javier Martinez Canillas Date: Thu Sep 10 17:17:57 2020 +0200 tftp: Roll-over block counter to prevent data packets timeouts Commit 781b3e5efc3 (tftp: Do not use priority queue) caused a regression when fetching files over TFTP whose size is bigger than 65535 * block size. grub> linux /images/pxeboot/vmlinuz grub> echo $? 0 grub> initrd /images/pxeboot/initrd.img error: timeout reading '/images/pxeboot/initrd.img'. grub> echo $? 28 It is caused by the block number counter being a 16-bit field, which leads to a maximum file size of ((1 << 16) - 1) * block size. Because GRUB sets the block size to 1024 octets (by using the TFTP Blocksize Option from RFC 2348 [0]), the maximum file size that can be transferred is 67107840 bytes. The TFTP PROTOCOL (REVISION 2) RFC 1350 [1] does not mention what a client should do when a file size is bigger than the maximum, but most TFTP hosts support the block number counter to be rolled over. That is, acking a data packet with a block number of 0 is taken as if the 65356th block was acked. It was working before because the block counter roll-over was happening due an overflow. But that got fixed by the mentioned commit, which led to the regression when attempting to fetch files larger than the maximum size. To allow TFTP file transfers of unlimited size again, re-introduce a block counter roll-over so the data packets are acked preventing the timeouts.
