When SO_OOBINLINE is enabled on a socket, MSG_OOB can be recv()ed without MSG_OOB flag, and ioctl(SIOCATMARK) will behaves differently. This patch adds some test cases for SO_OOBINLINE. Note the new test cases found two bugs in TCP. 1) After reading OOB data with non-inline mode, we can re-read the data by setting SO_OOBINLINE. # RUN msg_oob.no_peek.inline_oob_ahead_break ... # msg_oob.c:146:inline_oob_ahead_break:AF_UNIX :world # msg_oob.c:147:inline_oob_ahead_break:TCP :oworld # OK msg_oob.no_peek.inline_oob_ahead_break ok 14 msg_oob.no_peek.inline_oob_ahead_break 2) The head OOB data is dropped if SO_OOBINLINE is disabled if a new OOB data is queued. # RUN msg_oob.no_peek.inline_ex_oob_drop ... # msg_oob.c:171:inline_ex_oob_drop:AF_UNIX :x # msg_oob.c:172:inline_ex_oob_drop:TCP :y # msg_oob.c:146:inline_ex_oob_drop:AF_UNIX :y # msg_oob.c:147:inline_ex_oob_drop:TCP :Resource temporarily unavailable # OK msg_oob.no_peek.inline_ex_oob_drop ok 17 msg_oob.no_peek.inline_ex_oob_drop Signed-off-by: Kuniyuki Iwashima <kuniyu@amazon.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

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 reStructuredText 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.
