The big changes for IPMI that just went in had a few problems. These
have been in for-next for a while, each since about their creation date. I forgot the bugzilla reference on the second one (ipmi_si: Fix oops with PCI devices) so I rebased to add that. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJaLo1KAAoJEGHzjJCRm/+B0HsP/joYHLSzoAESfihnx9JD1dn6 JM8ZV8fu7e1ZpnrxyGj/dPLSBS1k8wsVKAEGrL5ETz4UOuwIR6/61wpzfyrQf/L5 0ZBhpv8dAxpHvFZGGE1NCF4jNlo20K0i8YQk9lUxB3Nml3udUd+GUA/Li5d2vGo4 e6xZyS15euNmHwnELaCguS9Vz79xusLmFvgicmi5l7+Y3X4Ul/sNL+pGySYUMqxU NvsH3fTDXJfRv2FCnJwn1sUGpPPPH0uYhaLKXNpekt0PgNNTlTzFWGnfRJrbD/+q OWXrfuqiwoCSRhfOXooI2vGAIZ+jjL/vBS9827EGjf0tWgTVnOx+wuDND15uZkxP LizUG0ZPcov0veDh1mExIBIU2sCGkZ+dlQeGLaVBQ4tNgbyJyWi5HiwvFc5r9s/e /ak0kkt9J54T4MgtEMBEEHSMatUixM8eXJ7K9ySZANP5vXlLmcpXVKBHEB42QWBN I1V5o1PVHxV8IrG/zOiWYBLYraWocEaNat/LzlbqGMfoVyb1gXpAI8Cbjphq1xOU 49J5oY6L8MHNIu0VkEV9MtIEyLAM/V/nd8WQ3YpD/4UJnVoWcorBQWSC7NssWFm8 5N4dq7kXSnUM4yA21PMogFCnRToO6nrK/ijxOkzWmPbDnvDDywQY/bnj7dAKFQri iQ67umU2z0+U4juY+Lls =3M4K -----END PGP SIGNATURE----- Merge tag 'for-linus-4.15-2' of git://github.com/cminyard/linux-ipmi Pull IPMI fixes from Corey Minyard. * tag 'for-linus-4.15-2' of git://github.com/cminyard/linux-ipmi: ipmi_si: fix crash on parisc ipmi_si: Fix oops with PCI devices ipmi: Stop timers before cleaning up the module |

ipmi_si: fix crash on parisc
This patch fixes ipmi crash on parisc introduced in the kernel 4.15-rc. The pointer io.io_setup is not initialized and thus it causes crash in try_smi_init when attempting to call new_smi->io.io_setup.

ipmi_si: Fix oops with PCI devices
When the IPMI PCI code was split out, some code was consolidated for setting the io_setup field in the io structure. The PCI code needed this set before registration to probe register spacing, though, so restore the old code for that function.

ipmi: Stop timers before cleaning up the module
System may crash after unloading ipmi_si.ko module
because a timer may remain and fire after the module cleaned up resources.
cleanup_one_si() contains the following processing.
/*
* Make sure that interrupts, the timer and the thread are
* stopped and will not run again.
*/
if (to_clean->irq_cleanup)
to_clean->irq_cleanup(to_clean);
wait_for_timer_and_thread(to_clean);
/*
* Timeouts are stopped, now make sure the interrupts are off
* in the BMC. 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.

--- <NMI exception stack> ---
To fix the problem I defined a flag, timer_can_start,
as member of struct smi_info.
The flag is enabled immediately after initializing the timer
and disabled immediately before waiting for timer deletion.

treewide: setup_timer() -> timer_setup()
This converts all remaining cases of the old setup_timer() API into using
timer_setup(), where the callback argument is the structure already
holding the struct timer_list. 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 \

This changes all DEFINE_TIMER() callbacks to use a struct timer_list

removed, none of these callbacks are using their argument currently, so
this renames the argument to "unused".

Char/Misc patches for 4.15-rc1
Here is the big set of char/misc and other driver subsystem patches for 4.15-rc1. There are small changes all over here, hyperv driver updates, pcmcia driver updates, w1 driver updats, vme driver updates, nvmem driver updates, and lots of other little one-off driver updates as well. The shortlog has the full details. Note, there will be a merge conflict in drivers/misc/lkdtm_core.c when merging to your tree as one lkdtm patch came in through the perf tree as well as this one. The resolution is to take the const change that this tree provides. All of these have been in linux-next for quite a while with no reported issues.

x86/mm: Limit mmap() of /dev/mem to valid physical addresses
One thing /dev/mem access APIs should verify is that there's no way that excessively large pfn's can leak into the high bits of the page table entry. 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: |

kmemcheck: remove annotations
Patch series "kmemcheck: kill kmemcheck", v2. 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. This patch (of 4): Remove kmemcheck annotations, and calls to kmemcheck from the kernel. [alexander.levin@verizon.com: correctly remove kmemcheck call from dma_map_sg_attrs] Link: http://lkml.kernel.org/r/20171012192151.26531-1-alexander.levin@verizon.com Link: http://lkml.kernel.org/r/20171007030159.22241-2-alexander.levin@verizon.com Signed-off-by: Sasha Levin <alexander.levin@verizon.com> Cc: Alexander Potapenko <glider@google.com> Cc: Eric W.

IPMI updates for 4.15
This is signed by my new key (919BFF81), which is now signed by my
old key.
This is a fairly large rework of the IPMI code, along with a bunch
of smaller fixes. 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.

Pull timer updates from Thomas Gleixner:
"Yet another big pile of changes:
- More year 2038 work from Arnd slowly reaching the point where we
need to think about the syscalls themself.
- A new timer function which allows to conditionally (re)arm a timer
only when it's either not running or the new expiry time is sooner
than the armed expiry time. This allows to use a single timer for
multiple timeout requirements w/o caring about the first expiry
time at the call site.
- A new NMI safe accessor to clock real time for the printk timestamp
work. Can be used by tracing, perf as well if required.
- A large number of timer setup conversions from Kees which got
collected here because either maintainers requested so or they
simply got ignored. As Kees pointed out already there are a few
trivial merge conflicts and some redundant commits which was
unavoidable due to the size of this conversion effort.
- Avoid a redundant iteration in the timer wheel softirq processing.
- Provide a mechanism to treat RTC implementations depending on their
hardware properties, i.e. don't inflict the write at the 0.5
seconds boundary which originates from the PC CMOS RTC to all RTCs.
No functional change as drivers need to be updated separately.
- The usual small updates to core code clocksource drivers. Nothing
really exciting"

License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns to READ_ONCE()/WRITE_ONCE()
Please do not apply this to mainline directly, instead please re-run the
coccinelle script shown below and apply its output.
For several reasons, it is desirable to use {READ,WRITE}_ONCE() in
preference to ACCESS_ONCE(), and new code is expected to use one of the
former. So far, there's been no reason to change most existing uses of
ACCESS_ONCE(), as these aren't harmful, and changing them results in
churn.
However, for some features, the read/write distinction is critical to
correct operation. To distinguish these cases, separate read/write
accessors must be used. This patch migrates (most) remaining
ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following
coccinelle script:
----
// Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and
// WRITE_ONCE()
// $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch

tpm-dev-common: Reject too short writes
tpm_transmit() does not offer an explicit interface to indicate the number of valid bytes in the communication buffer. Instead, it relies on the commandSize field in the TPM header that is encoded within the buffer. Therefore, ensure that a) enough data has been written to the buffer, so that the commandSize field is present and b) the commandSize field does not announce more data than has been written to the buffer. This should have been fixed with CVE-2011-1161 long ago, but apparently a correct version of that patch never made it into the kernel.

tpm: React correctly to RC_TESTING from TPM 2.0 self tests
The TPM can choose one of two ways to react to the TPM2_SelfTest command. It can either run all self tests synchronously and then return RC_SUCCESS once all tests were successful. Or it can choose to run the tests asynchronously and return RC_TESTING immediately while the self tests still execute in the background. The previous implementation apparently was not aware of those possibilities and attributed RC_TESTING to some prototype chips instead. With this change the return code of TPM2_SelfTest is interpreted correctly, i.e. the self test result is polled if and only if RC_TESTING is received. Unfortunately, the polling cannot be done in the most straightforward way. If RC_TESTING is received, ideally the code should now poll the selfTestDone bit in the STS register, as this avoids sending more commands, that might interrupt self tests executing in the background and thus prevent them from ever completing. But it cannot be guaranteed that this bit is correctly implemented for all devices, so the next best thing would be to use TPM2_GetTestResult to query the test result. But the response to that command can be very long, and the code currently lacks the capabilities for efficient unmarshalling, so it is difficult to execute this command. Therefore, we simply run the TPM2_SelfTest command in a loop, which should complete eventually, since we only request the execution of self tests that have not yet been done.

tpm_tis_spi: Use DMA-safe memory for SPI transfers
The buffers used as tx_buf/rx_buf in a SPI transfer need to be DMA-safe.
This cannot be guaranteed for the buffers passed to tpm_tis_spi_read_bytes
and tpm_tis_spi_write_bytes. Therefore, we need to use our own DMA-safe
buffer and copy the data to/from it.
The buffer needs to be allocated separately, to ensure that it is
cacheline-aligned and not shared with other data, so that DMA can work
correctly.

tpm/tpm_crb: Use start method value from ACPI table directly
This patch gets rid of dealing with intermediate flag for start method and use start method value from ACPI table directly. For ARM64, the locality is handled by Trust Zone in FW. The layout does not have crb_regs_head. It is hitting the following line. dev_warn(dev, FW_BUG "Bad ACPI memory layout"); Current code excludes CRB_FL_ACPI_START for this check. Now since ARM64 support for TPM CRB is added, CRB_FL_CRB_SMC_START should also be excluded from this check. For goIdle and cmdReady where code was excluding CRB_FL_ACPI_START only (do nothing for ACPI start method), CRB_FL_CRB_SMC_START was also excluded as ARM64 SMC start method does not have TPM_CRB_CTRL_REQ. However with special PPT workaround requiring CRB_FL_CRB_START to be set in addition to CRB_FL_ACPI_START and the addition flag of SMC start method CRB_FL_CRB_SMC_START, the code has become difficult to maintain and undrestand. It is better to make code deal with start method value from ACPI table directly.
