Resend (apologies, tried to send it to -users by mistake initially).
Hi all,
I am observing an interesting issue with the OpenWRT build process when
building on an up-to-date stretch host. It no longer works on NFS on
debian (it used to work).
If I run make with a clean freshly cloned directory tree on a normally
mounted filesystem it completes OK. If I do a fresh git clone, mount the
filesystem via nfs I get the following:
SHELL= flock /var/autofs/local/src/openwrt/tmp/.patch-2.7.5.tar.xz.flock
-c ' /var/autofs/local/src/openwrt/scripts/download.pl
"/var/autofs/local/src/openwrt/dl" "patch-2.7.5.tar.xz"
"e3da7940431633fb65a01b91d3b7a27a" "" "@GNU/patch"'
flock: /var/autofs/local/src/openwrt/tmp/.patch-2.7.5.tar.xz.flock: Bad
file descriptor
Makefile:23: recipe for target
'/var/autofs/local/src/openwrt/dl/patch-2.7.5.tar.xz' failed
The results are the same if I mount the system via autofs or directly
via command line mount. If I run the flock statement "by hand" it
completes OK as well so this happens only if it is invoked out of the
openwrt build process (I smell a race here somewhere...).
I wish I could pinpoint the exact moment it broke. However, as the
actual problem is with downloads/stamps it is difficult to determine the
actual point in time it stopped working.
I tried running the build on a "pristine" stretch with no updates it was
already broken so this most likely happened somewhere between jessie and
stretch.
Any ideas (I do not want to file a Debian bug before narrowing it down)?
Please try again with the following patch applied:
