accel-ppp.git/CMakeLists.txt, branch 1.15.0

release: 1.15.0

2026-10-29T09:33:01+00:00

Set the 1.15.0 changelog date and the fallback versions used when building without git metadata (CMakeLists.txt and cmake/cpack.cmake; the latter was left at 1.13.0 by the 1.14.0 release). List the metrics module among README features. Co-Authored-By: Claude Opus 5.5 Signed-off-by: Denys Fedoryshchenko

accel-cmd: convert millisecond timeouts to nanoseconds correctly

2026-10-28T18:47:22+00:00

The fractional part of a millisecond timeout was multiplied by 1000 instead of 1000000, so 1500ms became 1.0005 seconds. Correct the conversion and add a CTest regression covering subsecond values, second boundaries, microseconds, and invalid input. Initialize CTest before configuring the client subdirectory. Validation: Release build and CTest pass. The regression fails against upstream master at 1ms. Signed-off-by: Denys Fedoryshchenko

cmake: fix kernel module installation

2026-08-30T00:10:39+00:00

Install each module from its real build directory, propagate staged install roots, and fail when kbuild modules_install fails. Add a rootless CTest and CI regression for successful and failed installs. Best practices followed: Use the standard CMake DESTDIR and kbuild INSTALL_MOD_PATH staging interfaces: https://cmake.org/cmake/help/latest/envvar/DESTDIR.html https://docs.kernel.org/kbuild/modules.html#install-mod-path Check child command status with execute_process RESULT_VARIABLE: https://cmake.org/cmake/help/latest/command/execute_process.html Register repeatable tests with CTest add_test: https://cmake.org/cmake/help/latest/command/add_test.html

pptp: drop the out-of-tree kernel driver

2026-08-09T10:30:39+00:00

drivers/pptp is version 0.8.5 of the PPTP driver, the direct ancestor of mainline drivers/net/ppp/pptp.c. Mainline merged that code in 2.6.37 (2011) from the same author and has maintained it since; this copy received none of the subsequent fixes and is no longer worth carrying: - It cannot be built. struct flowi's nl_u union, the 3-argument ip_route_output_key(), sock_no_poll, the old ip_select_ident() signature and nf_reset() all disappeared long ago, so nothing past roughly 2.6.36 compiles and -DBUILD_PPTP_DRIVER=TRUE is a build failure everywhere. - It is not needed. The PPTP bits of accel-pppd/include/if_pppox.h are identical to the mainline UAPI header, so ctrl/pptp's socket(AF_PPPOX, SOCK_STREAM, PX_PROTO_PPTP) reaches the in-kernel module (alias net-pf-24-proto-2) unchanged. The daemon uses no interface the bundled driver added. The deleted drivers/pptp/if_pppox.h was included only by drivers/pptp/pptp.c; all other if_pppox.h includes use either the kernel UAPI header or accel-pppd's userspace copy. - It is unsafe. Among others: the pskb_may_pull() in pptp_rcv() is commented out, so the GRE header is parsed with no length validation at all; the skb->len - headersize comparison in pptp_rcv_core() underflows and leads to an out-of-bounds read and a negative skb_pull(); pptp_getname() copies uninitialised stack to userspace; and pptp_bind()/pptp_connect() never check sockaddr_len (CVE-2015-8569). Mainline fixed each of these years ago. Remove the directory along with the BUILD_PPTP_DRIVER option, the accel-pptp-kmod package and the ip_gre conflict warning, which only existed because this module claimed IPPROTO_GRE. accel-pppd/ctrl/pptp and accel-pppd/include/if_pppox.h are unaffected. PPTP now requires the kernel's own pptp module; kernels older than 2.6.37 are no longer supported.

sstp: add ppposeq transport to avoid userspace HDLC framing

2026-08-04T20:41:46+00:00

A pty is a byte stream, so the tty flip buffer merges frames written back to back and sstp has to re-delimit them with async HDLC escaping and a CRC-16 FCS. On a 1452-byte payload that is ~3600 ns per frame, most of it spent on the FCS. PPPOSEQ is a pppox protocol whose socket is the ppp endpoint itself, so one datagram is one frame and no framing is needed at all. The same payload takes ~380 ns per frame, about 9 times less. Requires kernel 2.6.37, the first with PX_MAX_PROTO 3, whose remaining slot it claims. Supported kernels are from 2.6.37 to 7.2. The new ppp-mode option selects the transport; auto, the default, falls back to async when the module is unavailable, so hosts with prebuilt kernels are unaffected. PPP_SYNC is removed, being disabled and unfixable over a pty: frame boundaries cannot be recovered from the stream, and coalescing cannot be prevented since frames arrive from the network stack.
