Package: src:linux
Version: 5.10.70-1
Severity: normal
Tags: upstream
Dear Maintainer,
When reading from a pty, a call to read(2) always returns a string ending in a
newline, except when the text written to the pty contains a multiple of 64
characters, plus the newline. In the exceptional case, a second call to read
returns just the newline.
In the previous debian release, buster, with kernel 4.19.0-18-amd64, a newline
was always returned irrespective of the size of the input.
This was discovered by students on our operating systems class. We include a
test program that exhibits the problem. The hardware referenced in this ticket
is a VM, but we saw similar results on hardware.
