Comment 9 Jaco Kroon 2017-11-06 14:05:22 UTC

The don't build patch is inappropriate.  We should rather fix the includes.

Further problems building against 4.13.10 kernel:

/var/tmp/portage/net-misc/dahdi-2.11.1/work/dahdi-linux-2.11.1/drivers/dahdi/dahdi-sysfs.c:273:2: error: unknown field 'dev_attrs' specified in initializer
  .dev_attrs = span_dev_attrs, and

I can confirm that with BOTH patches at the link Joe M supplied in comment 7, as well as the -v3 patch at the 356 DAHDI bug report dahdi also fails for me on opvxa1200.  This is due to touch_softlockup_watchdog declaration having moved from linux/sched.h to linux/nmi.h - I'm not sure which kernel version exactly yet.

This leaves:

In file included from ./include/linux/kobject.h:21:0,
                 from ./include/linux/module.h:17,
                 from /var/tmp/portage/net-misc/dahdi-2.11.1/work/dahdi-linux-2.11.1/drivers/dahdi/xpp/xbus-sysfs.c:24:
/var/tmp/portage/net-misc/dahdi-2.11.1/work/dahdi-linux-2.11.1/drivers/dahdi/xpp/xbus-sysfs.c:801:23: error: 'hwid_show' undeclared here (not in a function)
 static DEVICE_ATTR_RO(hwid);
./include/linux/sysfs.h:116:10: note: in definition of macro '__ATTR_RO'
  .show = _name##_show,      \
/var/tmp/portage/net-misc/dahdi-2.11.1/work/dahdi-linux-2.11.1/drivers/dahdi/xpp/xbus-sysfs.c:801:8  note: in expansion of macro 'DEVICE_ATTR_RO'
 static DEVICE_ATTR_RO(hwid);

I can't find any reference to a hwid attribute other than this, which is introduced by dev_attrs_groups-v3.patch - any objections to simply mangling the patch?

Sorry for only picking up on this report now - been using 4.0.9 kernel until very recently due to being the least unstable version in 4.X branch.  I'll attach individual patches here in a bit.  Just need to find which kernel version the nmi.h changed.

DISCLAIMER: I don't have all the hardware to test all of the various modules.

It does compile and it does merge with the additional four patches.  Three of the four patches comes from the Digium bug tracker (with a minor modification).  The fourth is a trivial patch to accomodate commit d151b27d3f86589308cd8c891fdfd2db5f8e80d6 in kernel 4.11 as submitted by Ingo Molnar and acked by Linus.  The commit message hints that linux/nmi.h may be renamed again at some point in the future, so when anyone picks that up, please contact me and I'll adjust the patch accordingly.
