commit 49917c129b1456585258b0ebe89a513ecef823a8
Author: Stefan Sperling <ssperling(a)sysmocom.de>
Date: Thu Mar 22 20:19:56 2018 +0100
preserve 'when' flags of new osmo_fd in ipaccess_rcvmsg()
ipaccess_rcvmsg() disposes of a temporary osmo_fd structure after
the RSL link comes up. It copies data from its temporary osmo_fd
to the new one returned by sign_link_up(). However, in doing so,
it clobbered the 'when' flags, which could differ between the two
osmo_fd structures.
For instance, BSC_FD_WRITE could be set on the new osmo_fd but
not on the old one, in case sign_link_up() has already enqueued
outbound messages using the new osmo_fd.
Because of this behaviour, a patch committed to osmo-bsc to address
issue #2719 did not work as intended and had to be reverted.
After this change, that osmo-bsc patch should work as intended
and issue #2719 can hopefully be resolved.
