linux-toradex.git/drivers/tty/synclinkmp.c, branch v3.2.6 Linux kernel for Apalis and Colibri modules TTY: snyclinkmp: forever loop in tx_load_dma_buffer() 2011-09-29T20:23:33+00:00 Dan Carpenter dan.carpenter@oracle.com 2011-09-27T06:20:50+00:00 53d785ccd918d571c227d459477793872676fc02 My main concern here was the line that said: copy_count = min_t(unsigned short,count,SCABUFSIZE); "count" is an unsigned int here so the cast to unsigned short truncates the upper bits. So if count is 0x10000 then copy_count is 0 and the loop never exits. "count" comes from skb->len in hdlcdev_xmit(). The other min_t() changes are just cleanups.

My main concern here was the line that said:
	copy_count = min_t(unsigned short,count,SCABUFSIZE);
"count" is an unsigned int here so the cast to unsigned short
truncates the upper bits.  So if count is 0x10000 then copy_count is
0 and the loop never exits.

"count" comes from skb->len in hdlcdev_xmit().

The other min_t() changes are just cleanups.
