Re: OPENBSD performance // intel NIC interrupts // interrupt moderation

Re: [patch] eliminate -Wsign-compare warning in imsg.c with clang on FreeBSD

Committed, thanks! Note: The patch didn't apply cleanly. There's been the following commit in the meantime, which probably is of interest for FreeBSD, too (there were corresponding changes in the imsg consumers on the same day). revision 1.12 date: 2015/12/05 13:06:52; author: claudio; state:

refine canaries

This is a kind of two steps forward, one step back diff. I would like for the canary to be placed directly adjacent to the end of the user specified size. No slack. To accomplish this, we record the original size of the allocation at the end, then we can walk backwards to find the canary.

Add SO_REUSEADDR when binding SO_REUSEPORT socket to multicast address

in_pcbbind and in6_pcbbind both extends SO_REUSEADDR for multicast addresses so that it turns into a SO_REUSEPORT. But the check is done in such a way that you cannot bind a SO_REUSEPORT-enabled socket to a multicast address *after* you bound a SO_REUSEADDR-enabled socket to the same address.

[vi/ex] Tilde expansion without forking off a shell

Hi people, the following patch allows vi (and ex) to do tilde expansion without forking off a shell. The algorithm is similar to the one in mg, modulo adaptions for the way vi handles line buffers and such. This allows editing files like `~/foobar` in secure (-S) mode, where fork and

[patch] malloc: add info about the largest consumers of memory

Hi, This patch adds additional informational to ddb's "show malloc" command about the largest consumers of memory. This is my first patch for OpenBSD, so I will be very grateful for any comments. Thanks in advance! Index: sys/kern/kern_malloc.c

[patch] malloc: size that was passed to free() should land into the same bucket

Hi, Currently two checks in free() function confirm the correctness of freedsize argument. I think that it's better to check that provided freedsize fall into the same bucket that was recorded in kmemusage struct: it covers both cases. Index: sys/kern/kern_malloc.c
