  "message": "TTY: fix tty_wait_until_sent on 64-bit machines\n\nFix overflow bug in tty_wait_until_sent on 64-bit machines, where an\ninfinite timeout (0) would be passed to the underlying tty-driver\u0027s\nwait_until_sent-operation as a negative timeout (-1), causing it to\nreturn immediately.\n\nThis manifests itself for example as tcdrain() returning immediately,\ndrivers not honouring the drain flags when setting terminal attributes,\nor even dropped data on close as a requested infinite closing-wait\ntimeout would be ignored.\n\nThe first symptom  was reported by Asier LLANO who noted that tcdrain()\nreturned prematurely when using the ftdi_sio usb-serial driver.\n\nFix this by passing 0 rather than MAX_SCHEDULE_TIMEOUT (LONG_MAX) to the\nunderlying tty driver.\n\nNote that the serial-core wait_until_sent-implementation is not affected\nby this bug due to a lucky chance (comparison to an unsigned maximum\ntimeout), and neither is the cyclades one that had an explicit check for\nnegative timeouts, but all other tty drivers appear to be affected.\n\nFixes: 1da177e4c3f4 (\"Linux-2.6.12-rc2\")\nCc: stable \u003cstable@vger.kernel.org\u003e\t# v2.6.12\nReported-by: ZIV-Asier Llano Palacios \u003casier.llano@cgglobal.com\u003e\nSigned-off-by: Johan Hovold \u003cjohan@kernel.org\u003e\nReviewed-by: Peter Hurley \u003cpeter@hurleysoftware.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n",
