| * | | ipmi/ipmi_powernv: remove outdated todo in powernv IPMI driverJeremy Kerr2018-01-161-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the IPMI core now queries device IDs dynamically, we no longer need this todo for implementing this in the powernv driver. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Corey Minyard <cminyard@mvista.com>
| * | | ipmi: Clear smi_info->thread to prevent use-after-free during module unloadMasamitsu Yamazaki2018-01-161-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During code inspection, I found an use-after-free possibility during unloading ipmi_si in the polling mode. If start_new_msg() is called after kthread_stop(), the function will try to wake up non-existing kthread using the dangling pointer. Possible scenario is when a new internal message is generated after ipmi_unregister_smi()[*1] and remains after stop_timer_and_thread() in clenaup_one_si() [*2]. Use-after-free could occur as follows depending on BMC replies. cleanup_one_si => ipmi_unregister_smi [*1] => stop_timer_and_thread => kthread_stop(smi_info->thread) [*2] => poll => smi_event_handler => start_new_msg => if (smi_info->thread) wake_up_process(smi_info->thread) <== use-after-free!! Although currently it seems no such message is generated in the polling mode, some changes might introduce that in thefuture. For example in the interrupt mode, disable_si_irq() does that at [*2]. So let's prevent such a critical issue possibility now. Signed-off-by: Yamazaki Masamitsu <m-yamazaki@ah.jp.nec.com> Signed-off-by: Corey Minyard <cminyard@mvista.com>

Most of that stuff is as simple as 'make ->poll() instances return __poll_t and do the same to local variables used to hold the future return value'. Some of the obvious brainos found in process are fixed (e.g. POLLIN misspelled as POLL_IN). At that point the amount of sparse warnings is low and most of them are for genuine bugs - e.g. ->poll() instance deciding to return -EINVAL instead of a bitmap. I hadn't touched those in this series - it's large enough as it is. Another problem it has caught was eventpoll() ABI mess; select.c and eventpoll.c assumed that corresponding POLL### and EPOLL### were equal. That's true for some, but not all of them - EPOLL### are arch-independent, but POLL### are not. The last commit in this series separates userland POLL### values from the (now arch-independent) kernel-side ones, converting between them in the few places where they are copied to/from userland. AFAICS, this is the least disruptive fix preserving poll(2) ABI and making epoll() work on all architectures. As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and it will trigger only on what would've triggered EPOLLWRBAND on other architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered at all on sparc.

| * ipmi: Stop timers before cleaning up the moduleMasamitsu Yamazaki2017-12-061-21/+23

Note that timers and CPU interrupts are off, * so no need for locks. */ while (to_clean->curr_msg || (to_clean->si_state != SI_NORMAL)) { poll(to_clean); schedule_timeout_uninterruptible(1); } si_state changes as following in the while loop calling poll(to_clean). SI_GETTING_MESSAGES => SI_CHECKING_ENABLES => SI_SETTING_ENABLES => SI_GETTING_EVENTS => SI_NORMAL As written in the code comments above, timers are expected to stop before the polling loop and not to run again. But the timer is set again in the following process when si_state becomes SI_SETTING_ENABLES. => poll => smi_event_handler => handle_transaction_done // smi_info->si_state == SI_SETTING_ENABLES => start_getting_events => start_new_msg => smi_mod_timer => mod_timer As a result, before the timer set in start_new_msg() expires, the polling loop may see si_state becoming SI_NORMAL and the module clean-up finishes. For example, hard LOCKUP and panic occurred as following. smi_timeout was called after smi_event_handler, kcs_event and hangs at port_inb() trying to access I/O port after release.

In particular, if people can use "very large physical page addresses" through /dev/mem to set the bits past bit 58 - SOFTW4 and permission key bits and NX bit, that could *really* confuse the kernel. We had an earlier attempt: ce56a86e2ade ("x86/mm: Limit mmap() of /dev/mem to valid physical addresses") ... which turned out to be too restrictive (breaking mem=... bootups for example) and had to be reverted in: 90edaac62729 ("Revert "x86/mm: Limit mmap() of /dev/mem to valid physical addresses"") This v2 attempt modifies the original patch and makes sure that mmap(/dev/mem) limits the pfns so that it at least fits in the actual pteval_t architecturally: - Make sure mmap_mem() actually validates that the offset fits in phys_addr_t ( This may be indirectly true due to some other check, but it's not entirely obvious. ) - Change valid_mmap_phys_addr_range() to just use phys_addr_valid() on the top byte ( Top byte is sufficient, because mmap_mem() has already checked that it cannot wrap. ) - Add a few comments about what the valid_phys_addr_range() vs. valid_mmap_phys_addr_range() difference is.

These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

As discussed at LSF/MM, kill kmemcheck. KASan is a replacement that is able to work without the limitation of kmemcheck (single CPU, slow). KASan is already upstream. We are also not aware of any users of kmemcheck (or users who don't consider KASan as a suitable replacement). The only objection was that since KASAN wasn't supported by all GCC versions provided by distros at that time we should hold off for 2 years, and try again. Now that 2 years have passed, and all distros provide gcc that supports KASAN, kill kmemcheck again for the very same reasons.

The major changes have been in the next tree for a couple of months, so they should be good to do in. - Some users had IPMI systems where the GUID of the IPMI controller could change. So rescanning of the GUID was added. The naming of some sysfs things was dependent on the GUID, however, so this resulted in the sysfs interface code in IPMI changing to remove that dependency and name the IPMI BMCs like other sysfs devices. - The ipmi_si_intf.c code was fairly bloated with all the different discovery methods (PCI, ACPI, SMBIOS, OF, platform, module parameters, hot add). The structure of how the interfaces were added was redone to make them more modular, then the individual methods were pulled out into their own files" * tag 'ipmi-for-4.15' of git://github.com/cminyard/linux-ipmi: (48 commits) ipmi_si: Delete an error message for a failed memory allocation in try_smi_init() ipmi_si: fix memory leak on new_smi ipmi: remove redundant initialization of bmc ipmi: pr_err() strings should end with newlines ipmi: Clean up some print operations ipmi: Make the DMI probe into a generic platform probe ipmi: Make the IPMI proc interface configurable ipmi_ssif: Add device attrs for the things in proc ipmi_si: Add device attrs for the things in proc ipmi_si: remove ipmi_smi_alloc() function ipmi_si: Move port and mem I/O handling to their own files ipmi_si: Get rid of unused spacing and port fields ipmi_si: Move PARISC handling to another file ipmi_si: Move PCI setup to another file ipmi_si: Move platform device handling to another file ipmi_si: Move hardcode handling to a separate file. ipmi_si: Move the hotmod handling to another file. ipmi_si: Change ipmi_si_add_smi() to take just I/O info ipmi_si: Move io setup into io structure ipmi_si: Move irq setup handling into the io struct ...

This required redoing the way the remove functions for some device interfaces worked, a new function named ipmi_si_remove_by_dev() allows the device to be passed in and detected instead of using driver data, which couldn't be filled out easily othersize. After this the platform handling should be decoupled from the smi_info structure and that handling can be pulled out to its own files. Signed-off-by: Corey Minyard <cminyard@mvista.com>
