11:17 AM DragonFlyBSD Revision b08bfb72 (dragonflybsd): KERN_PROC - Fix KERN_PROC_ARGS and KERN_PROC_CWD to return length if oldptr==NULL.

02:29 AM DragonFlyBSD Revision ea2c2549 (dragonflybsd): procfs - Don't reset fd offset when reading regs, fpregs, or dbregs files.

* For repeated reads, we can simply use pread(2). And this way, we allow for
normal shell tooling to work correctly... vadaszi

09:02 AM DragonFlyBSD Revision f940d57e (dragonflybsd): truss - Various small code cleanups.

08:05 AM DragonFlyBSD Revision b67e2056 (dragonflybsd): truss - Fail properly, if we suddenly are missing permissions.

* This avoids infinitely retrying the ioctl in a loop. If we are missing
permissions, it's reasonable to just give ... vadaszi

07:21 AM DragonFlyBSD Revision 6201675f (dragonflybsd): truss - Use pread(2) instead of seek+read for reading the process' memory.

* Also drastically simplifies get_string() by setting an absolute maximum
on the length of the string at MAXPATHLEN... vadaszi

05:08 AM DragonFlyBSD Revision f223e1c5 (dragonflybsd): virtio_blk - Only read num_queues config field when MultiQueue is supported.
