D. Wythe says: ==================== fix unexpected SMC_CLC_DECL_ERR_REGRMB error We can easily trigger the SMC_CLC_DECL_ERR_REGRMB exception within following script: server: smc_run nginx client: smc_run ./wrk -c 2000 -t 8 -d 20 http://smc-server And we can clearly see that this error is also divided into two types: 1. 0x09990003 2. 0x05000000/0x09990003 Which has the same root causes, but the immediate causes vary. The root cause of this issues is that remove connections from link group is not synchronous with add/delete rtoken entry, which means that even the number of connections is less that SMC_RMBS_PER_LGR_MAX, it does not mean that the connection can register rtoken successfully later. In other words, the rtoken entry may released, This will cause an unexpected SMC_CLC_DECL_ERR_REGRMB to be reported, and then this SMC connections have to fallback to TCP. This patch set handles two types of SMC_CLC_DECL_ERR_REGRMB exceptions from different perspectives. Patch 1: fix the 0x05000000/0x09990003 error. Patch 2: fix the 0x09990003 error. After those patches, there is no SMC_CLC_DECL_ERR_REGRMB exceptions in my test case any more. v1 -> v2: - add bugfix patch for SMC_CLC_DECL_ERR_REGRMB cause by server side v2 -> v3: - fix incorrect mail thread ==================== Signed-off-by: David S.

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.
