Client app can sends request target, custom header and body to HTTP layer. In response it receives all bytes as received from transport, aditionally we provide offset and length of headers and body. In addtion client app is now able to receive response with all status codes and Host header field is set in request at protocol layer.

2024-07-24session: delete and add application namespace do not create the global ↵Steven Luong4-65/+56
session table When an application namespace is added, we call session_table_is_alloced to see if we need to allocate a new session table. That check returns true even if we removed the session table. The fix is when we delete an application's global session table, we need to invalidate fib_index_to_table_index. Fixed test_vcl test script to run two tests back to back. The 1st test deletes the application namespace at the end. The 2nd test adds the application namespace in the beginning.

2024-07-15octeon: fix link down issueAlok Mishra1-0/+12
An issue is noticed when the link state of the ethernet interface is toggled to down and again brought up. The link status shows "up" in the "show interface", but shows "down" in "show hardware-interface". This issue does not occur when the link is brought up for the first time, but only manifests when the interface is brought down and up again. This happens because the device status and VNET_HW_INTERFACE_FLAG_LINK_UP aren't correctly updated during the port stop, preventing them from being updated during the port start. This patch fixes this issue in the port stop function. Type: fix Fixes: 01fe7ab88e Signed-off-by: Alok Mishra <almishra@marvell.com> Change-Id: Idbc5a6c31409a3d1c5b19e14a3c9509291175677
2024-07-12build: Fix crossbuilding definitionsRenato Botelho do Couto1-7/+8
CMAKE_C_COMPILER_TARGET doesn't need to be set when it's not cross compiling, and based on wrong identation of that line I suspect it was intended to be inside CMAKE_CROSSCOMPILING conditional. With this line moved inside, it ends up being the only place where COMPILER_SUFFIX is used, so, move its declaration there as well. It will not bring any change to currently supported systems but will make it easier to build VPP on systems running musl libc.

2024-07-12fib: fix covered_inherit_addMaxime Peim2-2/+57
When a FIB entry has multiple sources installed by covering inheritance, the first walk installs the covering source, which can be worse than the already used one (hence the source is not activated). If a covering path is added and a new fib cover walk is done, the deactivated source is compared to itself. This operation calls for a reactivation of the source which was not activated in the first place.

2024-07-12fib: improve ipv6 fib scalingBenoît Ganne4-406/+203
VPP IPv6 FIB relies on 2 bihash for all its VRFs: 1 for control plane and one for data plane. Because of that, control plane VRF walks time grows with the number of VRFs as it has to go through all the VRFs. In order to improve control plane performance with large number of VRFs, the control plane data structure is changed from a global bihash to a per-VRF hashtable, similarly to IPv4. Contrary to IPv4, there is only 1 hashtable per VRF and not 1 hashtable per prefix-length per VRF, which is a compromise between memory consumption and single VRF scaling.

2024-07-09vppinfra: fix huge page alloc error on 5.19+ kernelJay Wang1-0/+14
Running VPP on a NUMA system with 5.19+ kernel outputs the following error messages. 'show physmem' command confirms that VPP falls back to using normal 4K pages instead of the preallocated 1G huge pages. The root cause is that VPP uses move_pages()[1] to get the huge page node information. However, this misbehaves on the 5.19+ kernel due to changes introduced in its implementation[2]. Our proposed fix is retry obtaining NUMA node info with get_mempolicy()[3] only if we see -ENOENT returned in status from move_pages() and huge pages are used. Additionally, we use mincore()[4] to check if pages are allocated and in memory to avoid the possibility of get_mempolicy() falsely allocating a new page. buffer [warn ]: numa[1] falling back to non-hugepage backed buffer pool () vpp# show physmem used-pages 2 reserved-pages 16 default-page-size 1G lookup-page-size 4K arena 'buffers-numa-0' pages 1 subpage-size 1G numa-node 0 shared fd 5 arena 'buffers-numa-1' pages 1 subpage-size 4K numa-node 1 shared fd 6 [1] https://man7.org/linux/man-pages/man2/move_pages.2.html [2] https://lore.kernel.org/linux-mm/91da2c3b-96f1-bb03-8fff-4c38f31cb9be@huawei.com/ [3] https://man7.org/linux/man-pages/man2/get_mempolicy.2.html [4] https://man7.org/linux/man-pages/man2/mincore.2.html Type: fix Signed-off-by: Jay Wang <jay.wang2@arm.com> Change-Id: Ia423745423bb080404292333ef95455a4950ce0a

RFC6935 section 5 states that, by default, the UDP checksum must be computed when originating an IPv6 UDP packet. The default behavior may be overridden when conditions defined by RFC6936 are satisfied. However this implementation does not satisfy all the conditions so the checksum must be computed. After ESP encryption the packet is an IPv6 UDP packet so set the l3_hdr_offset and l4_hdr_offset values, and set the UDP_CKSUM offload flag in the buffer.
