These patches are made on top of branch: git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git per-namespace-ipc-sysctls-for-v5.18 After discussion, I took into account Eric Biederman's fixes. With these changes, the hacks of passing namespace through .extra1 are not required. With the current design of sysctl dynamic memory allocation is necessary. Yes, Linus, these changes are not the refactoring you were talking about, but I plan to try to do such a refactoring in the my next patchset. -- Alexey Gladkov (4): ipc: Remove extra1 field abuse to pass ipc namespace ipc: Use proper ipc namespace ipc: Check permissions for checkpoint_restart sysctls at open time ipc: Remove extra braces ipc/ipc_sysctl.c | 108 +++++++++++++++++++++-------------------------- 1 file changed, 49 insertions(+), 59 deletions(-) -- 2.33.2
