2022-12-25treewide: Convert del_timer*() to timer_shutdown*()Steven Rostedt (Google)1-1/+1
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/[email protected]/ Signed-off-by: Steven Rostedt (Google) <[email protected]> Acked-by: Pavel Machek <[email protected]> [ LED ] Acked-by: Kalle Valo <[email protected]> [ wireless ] Acked-by: Paolo Abeni <[email protected]> [ networking ] Signed-off-by: Linus Torvalds <[email protected]>

2022-12-21m68k: remove broken strcmp implementationLinus Torvalds1-20/+0
The m68 hand-written assembler version of strcmp() has always been broken: it returns the difference between the first non-matching byte done as a 8-bit subtraction. That is _almost_ right, but is broken for the overflow case. The strcmp() function should indeed return the sign of the difference between the first byte that differs, but the subtraction needs to be done in a wider type than 'char'. Otherwise the ordering isn't actually stable. This went unnoticed for basically forever, because nobody ever cares about non-US-ASCII orderings in the kernel (in fact, most users only care about "exact match or not"), so overflows don't really happen in practice, even if it was very very wrong. But that mostly unnoticeable bug becomes very noticeable by the recent change to make 'char' be unsigned in the kernel across all architectures (commit 3bc753c06dd0: "kbuild: treat char as always unsigned"). Because the code not only did the subtraction in the wrong type width, it also used 'char' to then make the compiler expand the result from an 8-bit difference to the 'int' return value. So now with an unsigned char that incorrect arithmetic width was then not even sign-expanded, and always returned just a positive integer. We could re-instate the old broken code by just turning the 'char' into 'signed char' as has been done elsewhere where people depended on the signedness of 'char', but since the whole function was broken to begin with, and we have a non-broken default fallback implementation, let's just remove this broken function entirely.

With that change only alpha has one entry left (MADV_DONTNEED is 6 vs 4 on others) which is different. To prevent an ABI breakage, a wrapper is included which translates old MADV values to the new ones, so existing userspace isn't affected. Reason for that patch is, that some applications wrongly used the standard MADV_xxx values even on some non-x86 platforms and as such those programs failed to run correctly on parisc (examples are qemu-user, tor browser and boringssl). Then the kgdb console and the LED code received some fixes, and some 0-day warnings are now gone. Finally, the very last compile warning which was visible during a kernel build is now fixed too (in the vDSO code).

2022-12-17parisc: Align parisc MADV_XXX constants with all other architecturesHelge Deller3-16/+43
Adjust some MADV_XXX constants to be in sync what their values are on all other platforms. There is currently no reason to have an own numbering on parisc, but it requires workarounds in many userspace sources (e.g. glibc, qemu, ...) - which are often forgotten and thus introduce bugs and different behaviour on parisc. A wrapper avoids an ABI breakage for existing userspace applications by translating any old values to the new ones, so this change allows us to move over all programs to the new ABI over time.

2022-12-17powerpc/msi: Fix deassociation of MSI descriptorsMarc Zyngier5-0/+5
Since 2f2940d16823 ("genirq/msi: Remove filter from msi_free_descs_free_range()"), the core MSI code relies on the msi_desc->irq field to have been cleared before the descriptor can be freed, as it indicates that there is no association with a device anymore. The irq domain code provides this guarantee, and so does s390, which is one of the two architectures not using irq domains for MSIs. Powerpc, however, is missing this particular requirements, leading in a splat and leaked MSI descriptors. Adding the now required irq reset to the handful of powerpc backends that implement MSIs fixes that particular problem.
