pf: source tracking limits don't do what the man page says

Hello group, I'm hunting some bugs in FreeBSD's pf and I thought to ask here to better undernstad how the global source tracking is supposed to work in the reference implementation of pf. Or maybe it does not work, maybe this ia s bug report. I have the following ruleset on OpenBSD 7.3. The

mg: enable no-tab-mode

The `no-tab-mode' minor mode is currently hidden behind some #ifdef, and I'd like to enable it since it's really useful. It's the equivalent of vi' `expandtab', i.e. makes the TAB key inserting spaces up to the next tab stop. My plan would be to follow-up with a diff to make the tab width customi

vmd(8): fix restoring virtio devs on vm receive

Moving vmd to use zero-copy semantics for virtqueues introduced a bug in the vm send/receive functionality. The host va is potentially invalid on restore if vmd has restarted and re-randomized the address space of the vmm process that forks vm's. This NULL's out the hva to and resets it on restore

Call sysctl_source() with shared netlock

It seems rt_setsource() needs some attention, but sysctl_source() could be called with shared netlock just now. Index: sys/net/rtsock.c === RCS file: /cvs/src/sys/net/rtsock.c,v retrieving revision 1.359 diff -u -p -r1.359 rtsock.c --

Remove kernel lock from ifa_ifwithaddr()

We use netlock to protect `if_list' and `ifa_list' lists, and the `ifa' dereference, so kernel lock within ifa_ifwithaddr() is wrong. We have no problems, because we call ifadel()/ifafree() with kernel lock held, but we should not rely on this. So use netlock assertion within ifa_ifwithaddr() inst

dwmshc(4): emmc on rk3568

the emmc controller on rk3568 (so also rk3566) and rk3588 is largely a sdhc(4) controller, but with a bunch of extra registers up top that get involved in handling high speed modes. i could have added this to sdhc_fdt.c, but the names and number of registers involved were going to be cumbersome, a

malloc leak detection available in -current

Hi, OpenBSD current now has built-in malloc leak detection. Make sure you run current and have debug symbols (OpenBSD base libraries have debug symbols, compile your own program with -g). To record the leak report: $ MALLOC_OPTIONS=D ktrace -tu a.out To view the leak report: $ kdump -u malloc
