[ Upstream commit 4ce62d5b2f7aecd4900e7d6115588ad7f9acccca ] Some usb drivers try to set small skb->truesize and break core networking stacks. In this patch, I removed one of the skb->truesize overide. I also replaced one skb_clone() by an allocation of a fresh and small skb, to get minimally sized skbs, like we did in commit1e2c611723("net: cdc_ncm: reduce skb truesize in rx path") Fixes:f8ebb3ac88("net: usb: ax88179_178a: Fix packet receiving") Reported-by: shironeko <shironeko@tesaguri.club> Closes: https://lore.kernel.org/netdev/c110f41a0d2776b525930f213ca9715c@tesaguri.club/ Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Jose Alonso <joalonsof@gmail.com> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://lore.kernel.org/r/20240421193828.1966195-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> 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.
