Justin Iurman says: ==================== Mitigate double allocations in ioam6_iptunnel Commitdce525185b("net: ipv6: ioam6_iptunnel: mitigate 2-realloc issue") fixed the double allocation issue in ioam6_iptunnel. However, since commit92191dd107("net: ipv6: fix dst ref loops in rpl, seg6 and ioam6 lwtunnels"), the fix was left incomplete. Because the cache is now empty when the dst_entry is the same post transformation in order to avoid a reference loop, the double reallocation is back for such cases (e.g., inline mode) which are valid for IOAM. This patch provides a way to detect such cases without having a reference loop in the cache, and so to avoid the double reallocation issue for all cases again. v1: https://lore.kernel.org/netdev/20250410152432.30246-1-justin.iurman@uliege.be/T/#t ==================== Link: https://patch.msgid.link/20250415112554.23823-1-justin.iurman@uliege.be 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.
