From c2f2c51c53e91232e6f2aa686d734728ad703f9f Mon Sep 17 00:00:00 2001 From: Michal Soltys Date: Wed, 27 Jul 2016 00:57:01 +0200 Subject: vconsole: don't do GIO_SCRNMAP / GIO_UNISCRNMAP GIO_SCRNMAP / GIO_UNISCRNMAP are related to what setfont does with -m option - namely setting intermediate map from 8bit values into unicode values. This map is global, so single setfont invocation sets it for all applicable consoles. Furthermore calling GIO_SCRNMAP before GIO_UNISCRNMAP causes issues as the former corrupts values > 255 (UNI alone would be sufficient). The bug can be easily tested with the following conf: KEYMAP=pl FONT=LatArCyrHeb-16 FONT_MAP=8859-2 --- src/vconsole/vconsole-setup.c | 10 ---------- 1 file changed, 10 deletions(-) (limited to 'src/vconsole') diff --git a/src/vconsole/vconsole-setup.c b/src/vconsole/vconsole-setup.c index 1118118450..abf3871fd8 100644 --- a/src/vconsole/vconsole-setup.c +++ b/src/vconsole/vconsole-setup.c @@ -192,8 +192,6 @@ static int font_load_and_wait(const char *vc, const char *font, const char *map, */ static void font_copy_to_all_vcs(int fd) { struct vt_stat vcs = {}; - unsigned char map8[E_TABSZ]; - unsigned short map16[E_TABSZ]; struct unimapdesc unimapd; _cleanup_free_ struct unipair* unipairs = NULL; int i, r; @@ -234,14 +232,6 @@ static void font_copy_to_all_vcs(int fd) { cfo.height = vcs.v_active-1; /* tty1 == index 0 */ (void) ioctl(vcfd, KDFONTOP, &cfo); - /* copy map of 8bit chars */ - if (ioctl(fd, GIO_SCRNMAP, map8) >= 0) - (void) ioctl(vcfd, PIO_SCRNMAP, map8); - - /* copy map of 8bit chars -> 16bit Unicode values */ - if (ioctl(fd, GIO_UNISCRNMAP, map16) >= 0) - (void) ioctl(vcfd, PIO_UNISCRNMAP, map16); - /* copy unicode translation table */ /* unimapd is a ushort count and a pointer to an array of struct unipair { ushort, ushort } */ -- cgit v1.2.3-54-g00ecf
