[ Upstream commit eb356e6dc15a30af604f052cd0e170450193c254 ] If is_closed is set, and the event list is empty, then read() will return -EIO without blocking. After setting is_closed in ib_uverbs_free_event_queue(), we do trigger a wake_up on the poll_wait, but the fops->poll() function does not check it, so poll will continue to sleep on an empty list. Fixes: 14e23bd6d221 ("RDMA/core: Fix locking in ib_uverbs_event_read") Link: https://lore.kernel.org/r/0-v1-ace813388969+48859-uverbs_poll_fix%25jgg@mellanox.com Reviewed-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com> Signed-off-by: Sasha Levin <sashal@kernel.org> |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
