Description
In the Linux kernel, the following vulnerability has been resolved:
net: tls: avoid hanging tasks on the tx_lock
syzbot sent a hung task report and Eric explains that adversarial receiver may keep RWIN at 0 for a long time, so we are not guaranteed to make forward progress. Thread which took tx_lock and went to sleep may not release tx_lock for hours. Use interruptible sleep where possible and reschedule the work if it can't take the lock.
Testing: existing selftest passes
