The libkcapi test which causes kernel panic is aead asynchronous vmsplice multiple test. ./bin/kcapi -v -d 4 -x 10 -c "ccm(aes)" -q 4edb58e8d5eb6bc711c43a6f3693daebde2e5524f1b55297abb29f003236e43d -t a7877c99 -n 674742abd0f5ba -k 2861fd0253705d7875c95ba8a53171b4 -a fb7bc304a3909e66e2e0c5ef952712dd884ce3e7324171369f2c5db1adc48c7d This patch avoids dma_mapping of a zero length sg which causes the panic, by using sg_nents_for_len which maps only upto a specific length Signed-off-by: Ayush Sawal <ayush.sawal@chelsio.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
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.
