jschoubben	d13f74df40	A node that cannot open /dev/net/tun takes no image build, and every node loads tun at boot and keeps its running kernel's modules ... An image build node up 24 days had lost its running kernel's modules to a linux-lts upgrade, so tun could not load and every RUN line failed in pasta. mesh-build-image now proves the tun device and, whatever its look refuses, judges its node not eligible (capacity 0 with the reason), so the asks go to a node that can build them. The kernel module loads tun at boot and declares kernel-modules-hook, which keeps the running kernel's modules across an upgrade. Needs mesh-sdk fix/ace-tun (Puller.Eligible).	2026-10-28 12:44:58 +01:00
jschoubben	e4373768af	issue 1841/S14: declare the fallback kernel and its headers after the boot-entries unit ... ADR 0508 §9: every DKMS module is built for the fallback kernel too, and its entry is in place first.	2026-10-22 14:27:24 +02:00
jschoubben	2cb2e27cdf	issue 1838: name the kernel module's fixtures by what they show (as in the fix's own branch)	2026-10-22 14:27:15 +02:00
jschoubben	0f4e631cdd	issue 1841/S15: place the fallback kernel's boot entry from the loader the machine booted with ... ADR 0508 §9 and §10: systemd-boot gets an entry from the booted command line, GRUB a regenerated menu only when its kernels change, a found kernel-copying hook is taken over, a full boot partition fails loudly.	2026-10-22 14:26:59 +02:00

jschoubben	c816cafc00	The kernel module's transparent-huge-pages defaults to madvise, the mesh's chosen value (hq issue 856, ADR 0381 §2, §3)	2026-10-15 22:45:07 +02:00
jschoubben	ab1811d003	Reload, not restart, the huge pages unit when the setting changes (hq issue 746) ... A restart ran restore then apply, so every change passed back through the found mode and rotated the journal again. Reload applies the new value directly; restore also drops its state; no rotation while the machine boots; the unit is sandboxed.	2026-10-14 23:42:49 +02:00
jschoubben	3a84044ece	Add the kernel module: transparent huge pages set per machine (hq issue 746) ... With THP 'always' journald's mmapped journal files sit in 2 MiB folios, so each small journal write dirties and writes back 2 MiB; on the control node that saturated the root mirror holding the bus store and the store, and the controller lost its lease. The module sets the mode from a per-machine setting (default always, the kernel's own, so assigning it changes nothing until a machine sets madvise), verifies it took, rotates the journal once so new files are mapped under the new mode, gives back what it found when stopped, and serves kernel_huge_pages to measure file_thp per unit.	2026-10-14 23:31:13 +02:00
