From: Sebastian Huber <sh@sourceware.org> To: newlib-cvs@sourceware.org Subject: [newlib-cygwin] Jail and capability mode for shm_rename; Date: Mon, 11 Jul 2022 11:51:03 +0000 (GMT) [thread overview] Message-ID: <20220711115103.D1443385354C@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=0c854dd6d15774e12323110b699e2d0c90b7635a commit 0c854dd6d15774e12323110b699e2d0c90b7635a Author: David Bright <dab@FreeBSD.org> Date: Mon Nov 18 13:31:16 2019 +0000 Jail and capability mode for shm_rename; add audit support for shm_rename Co-mingling two things here: * Addressing some feedback from Konstantin and Kyle re: jail, capability mode, and a few other things * Adding audit support as promised. The audit support change includes a partial refresh of OpenBSM from upstream, where the change to add shm_rename has already been accepted. Matthew doesn't plan to work on refreshing anything else to support audit for those new event types.
