Tony Nguyen says: ==================== ice: fix synchronization between .ndo_bpf() and reset Larysa Zaremba says: PF reset can be triggered asynchronously, by tx_timeout or by a user. With some unfortunate timings both ice_vsi_rebuild() and .ndo_bpf will try to access and modify XDP rings at the same time, causing system crash. The first patch factors out rtnl-locked code from VSI rebuild code to avoid deadlock. The following changes lock rebuild and .ndo_bpf() critical sections with an internal mutex as well and provide complementary fixes. * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue: ice: do not bring the VSI up, if it was down before the XDP setup ice: remove ICE_CFG_BUSY locking from AF_XDP code ice: check ICE_VSI_DOWN under rtnl_lock when preparing for reset ice: check for XDP rings instead of bpf program when unconfiguring ice: protect XDP configuration with a mutex ice: move netif_queue_set_napi to rtnl-protected sections ==================== Link: https://patch.msgid.link/20240903183034.3530411-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@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 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.
