Fix error when refilling netmap buffers that resulted in the first buffer of the successive passes through ifl_bus_addrs[] leaving the first value unset (tmp_pidx started at 1, not zero after the first time through the loop). Leave the one unused buffer required by some NICs visible in the netmap ring rather than hidden. There will always be a buffer in use by the kernel now when an iflib driver is used via netmap. Always get the netmap slot index via netmap_idx_n2k() to account for nkr_hwofs in a consistent way. Split shared functionality into new functions. iru_init(): shared by _iflib_fl_refill() and netmap_fl_refill() netmap_fl_refill(): shared by iflib_netmap_rxsync() and iflib_netmap_rxq_init() PR: 222744 Reported by: Shirkdog <mshirk@daemon-security.com> Reviewed by: sbruno Approved by: sbruno (mentor) Sponsored by: Limelight Networks Differential Revision: https://reviews.freebsd.org/D12769 |

FreeBSD Source:

was last revised on:
FreeBSD
For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel
and installkernel
targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel
and installkernel
targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
devices, not just those commonly used.
