                             BASH PATCH REPORT
                             =================

Bash-Release:   4.4
Patch-ID:       bash44-018

Bug-Reported-by:        Siteshwar Vashisht <address@hidden>
Bug-Reference-ID:       <address@hidden>
Bug-Reference-URL:      https://bugzilla.redhat.com/show_bug.cgi?id=1466737

Bug-Description:

Under certain circumstances (e.g., reading from /dev/zero), read(2) will not
return -1 even when interrupted by a signal. The read builtin needs to check
for signals in this case.

Patch (apply with `patch -p0'):
