loader has some magic code to switch its output terminal to a serial console under certain circumstances. In F15 and earlier it worked basically like this: 1. if a 'weird' serial device (xvc0, hvc0, hvsi[0-2]) exists, use that 2. else if /dev/console is actually a serial device, use that 3. else if 'serial' was on the boot cmdline, use ttyS0 4. else just use tty1 Commit 422702a3 refactored the serial handling into its own file, and accidentally changed this behavior so that the serial devices were never checked unless 'serial' was on the commandline. Restoring this behavior means that users of special serial consoles (e.g. POWER systems and others with /dev/hvc0 and no graphics) don't see their installs hang after 'Starting Anaconda version XXX..." --- loader/serial.c | 8 +++++--- 1 files changed, 5 insertions(+), 3 deletions(-) diff --git a/loader/serial.c b/loader/serial.c index fa4c9a5..735ee9e 100644 --- a/loader/serial.c +++ b/loader/serial.c @@ -73,7 +73,7 @@ static int serial_requested(GHashTable *cmdline) { return 0; } -static int get_serial_fd() { +static int get_serial_fd(GHashTable *cmdline) { int i, fd = -1; int weird = 0; char twelve = 12; @@ -114,15 +114,17 @@ static int get_serial_fd() { restore_mode(&orig_cmode); + /* check to see if /dev/console is actually a serial device */ if (fd < 0 && ioctl(0, TIOCLINUX, &twelve) < 0) { console = "/dev/console"; if (ioctl(0, TIOCGSERIAL, &si) == -1) console = NULL; } - else + else if (serial_requested(cmdline)) console = "/dev/ttyS0"; + /* get an fd for the console if we don't already have one */ if (console && !weird) { fd = open(console, O_RDWR, 0); if (fd < 0) @@ -161,7 +163,7 @@ int init_serial(struct termios *orig_cmode, int *orig_flags, GHashTable *cmdline */ get_mode_and_flags(orig_cmode, orig_flags); - if (!serial_requested(cmdline) || (fd = get_serial_fd()) == -1) { + if ((fd = get_serial_fd(cmdline)) == -1) { /* This is not a serial console install. */ serial = 0; if ((fd = open("/dev/tty1", O_RDWR, 0)) < 0) { -- 1.7.7.4 _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/anaconda-devel-list
