Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2190250 Upstream Status: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=292a089d78d3e2f7944e60bb897c977785a321e3 Conflicts: * Avoiding commit <d87d44f7ab35> ("ARM: omap1: move CF chipselect setup to board file") and commit <df99e7bbbec3> ("ARM: omap1: use pci_remap_iospace() for omap_cf") with their ARM series. Also, this considers the fixes on i40e_main.c that have been partially applied through RHEL commit <3731942e6257>. commit 292a089d78d3e2f7944e60bb897c977785a321e3 Author: "Steven Rostedt (Google)" <rostedt@goodmis.org> Date: Tue, 20 Dec 2022 13:45:19 -0500 Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed. The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case. This was created by using a coccinelle script and the following commands: $ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); ) $ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch Link: https://lore.kernel.org/lkml/20221123201306.823305113@linutronix.de/ Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Pavel Machek <pavel@ucw.cz> [ LED ] Acked-by: Kalle Valo <kvalo@kernel.org> [ wireless ] Acked-by: Paolo Abeni <pabeni@redhat.com> [ networking ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Desnes Nunes <desnesn@redhat.com> |
