Hello,
In the protocol() function in krlogind.c the read on the pty is not
checked for the POSIX error equivalent for EWOULDBLOCK. The POSIX read
returns -1 and sets errno to EAGAIN (why?) instead. I just added a
#ifdef based on POSIX_SIGNALS since that indicates POSIX and nothing
else really applies. Maybe just checking for both EAGAIN and EWOULDBLOCK
in the same if would be better?
Thank you
Andrew Gross
=========================================================================
if (ibits & (1<<p)) {
pcc = read(p, pibuf, sizeof (pibuf));
pbp = pibuf;
#ifdef POSIX_SIGNALS
if (pcc < 0 && errno == EAGAIN)
#else
if (pcc < 0 && errno == EWOULDBLOCK)
#endif
pcc = 0;
else if (pcc <= 0)
break;
=========================================================================
