| [CI] 2nd attempt at fixing GH CI workflow | 2 months ago |
| mfmhd: take port, irq and flags from mfm= in /bootopts Use struct isa_conf for mfm= so the port, irq and flag bits come from /bootopts, with the defaults in ports.h. Drops CONFIG_MFMHD_PORT, which needed a rebuild to change, and the stale mfm globals in main.c. | 1 month ago |

| 286 protected-mode kernel HAL (rebased onto ghaerr/pmode) Boot the ELKS kernel in 80286 protected mode: real->PM mode switch, GDT/IDT, ring-0 execution, and a full port of the memory model to GDT selectors. Runs to an interactive shell and multi-user telnet login over the network (ne2k -> ktcp -> telnetd -> pty -> login) on QEMU/KVM. Rebased onto the pmode branch (#2721), adopting its struct segment base(selector)/para(physical) convention: seg->base is the GDT selector handed out via SEG_HANDLE(), the arena manages the physical paragraph in seg->para, and seg_pm_attach() builds each descriptor from para and stores the selector in base -- dropping the port's parallel 'sel' member and collapsing many CONFIG_286_PMODE ifdefs into pmode's LINADDR/BASE/KERNEL_CS/ KERNEL_DS/BIOSSEG/VIDEOSEG macros. - pm_enter.S mode switch + gdt_init descriptors (KCODE/KDATA/KFTEXT plus setup/optseg/biosdata/video/track selectors) and an IDT fault reporter. - PIC remap, IRQ trampolines and the syscall path reworked for PM selectors. - directfd DMA via desc_base/LINADDR; buffer cache, exec, fork and signals use selectors; compressed-exec (elks-compress) support. - /dev/kmem returns loadable KERNEL_CS/DS and decodes the PM seek window, so ps/meminfo read the task table (argv COMMAND still needs a selector-aware protocol or procfs). - compile-time config validation in pm286.c; small single-segment PM config template + mkimg.sh contiguous-image builder; .gitattributes keeps *.config LF for the build tooling. Builds and boots in 286 PM (ibmpc-286pm-small.config), verified end to end including telnet login over ne2k under the pmode base/para memory manager.

| [net] Fix network hang, leak and race issues in kernel and ktcp tcpdev_read()/tcpdev_connect(): Return -EPIPE or -ECONNREFUSED instead of no reply at all, which would hang the network due to the read/connect being blocked on a single reply buffer in the tcpdev ktcp<->kernel transfer driver. Fixes network stack hangs during read or connect when CB is deallocated through a received RST or any other reason that deallocates an active CB. tcp_established(): decrement tcpcb_need_push when a RST frees a CB that still has unread data to stop continual AVAIL_DATA notifications. tcp_synrecv(): free the cloned CB on RST rather than only resetting state, each half-open RST leaked ~4.5K. inet_process_tcpdev() / TDT_ACCEPT: Copy accept() result out immediately and and release bufin_sem, which breaks a bufin_sem/bufout_sem deadlock between ktcp and ftpd under load. | 29 days ago |
