readtoken1() into a real function of its own (inspired by a
similar change made by FreeBSD - the other internal routines
they moved out are expected to move out here as well soon.)
This change helps avoid gcc 5.3 demanded (not required!) volatile
noise which would slow down parsing. (from kre)
This effectively fixes PaX ASLR with 32-bits emulation on 64-bits
platforms. Without this knowledge, the offset applied for 32-bits
programs was really meant for a 64-bits address space - thus
shifting the address up to 12 bits, with a success rate of about
1/4096. This offset is calculated once in the lifetime of the
process, which therefore behaved normally when able to start.
Fixes kern/50469, probably also kern/50986
Tested on NetBSD/amd64 (emul_netbsd32)
As discussed on current-users@, SANE uses ugen via libusb and not
uscanner, so users are not well served by having uscanner. Consensus
is that addressing how to adjust permissions for scanners should not
block restoring basic functionionality.
(Compile-tested only, but there are multiple reports of this being the
right approach.)
- there is a ktr_version field
- the ordering of ktr_type and ktr_version is byte-order dependent
- ktr_time is now a timespec, not a timeval
- there's now a ktr_lid field
- there is no such thing as a ktr_buf field and it's certainly not
a caddr_t.
XXX: I would appreciate it if someone who knows how this stuff works
XXX: could review this file in case it's still lying in some more
XXX: subtle way.
sys/signal.h and sys/time.h. Also add sys/uio.h which is needed and
for some probably historical/obsolete reason has been documented as a
prerequisite instead of included directly.
This also requires sys/param.h for MAXCOMLEN (blah) but for now at
least shift that to the documentation instead of including it
directly as it's a sewer.
