|\ | | | | | | | | | | | | | | Pull IPMI fix from Corey Minyard: "Fix a compile error on IPMI when ACPI is disabled" * tag 'for-linus-4.5-2' of git://git.code.sf.net/p/openipmi/linux-ipmi: ipmi: put acpi.h with the other headers
| * ipmi: put acpi.h with the other headersTony Camuso2016-02-031-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enclosing '#include <linux/acpi.h>' within '#ifdef CONFIG_ACPI' is unnecessary, since it has its own conditional compile for CONFIG_ACPI. Commit 0fbcf4af7c83 ("ipmi: Convert the IPMI SI ACPI handling to a platform device") exposed this as a problem for platforms that do not support ACPI when it introduced a call to ACPI_PTR() macro outside of the CONFIG_ACPI conditional compile. This would have been perfectly acceptable if acpi.h were not conditionally excluded for the non-acpi platform, because the conditional compile within acpi.h defines ACPI_PTR() to return NULL when compiled for non acpi platforms.

| * | keys, trusted: seal with a TPM2 authorization policyJarkko Sakkinen2015-12-201-4/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TPM2 supports authorization policies, which are essentially combinational logic statements repsenting the conditions where the data can be unsealed based on the TPM state. This patch enables to use authorization policies to seal trusted keys. Two following new options have been added for trusted keys: * 'policydigest=': provide an auth policy digest for sealing. * 'policyhandle=': provide a policy session handle for unsealing. If 'hash=' option is supplied after 'policydigest=' option, this will result an error because the state of the option would become mixed.

So we have to wait for an outstanding response before sending a new request to avoid trying to put a 2nd request into the CRQ. Also reset the res_len before sending a command so we will end up in that wait_event_interruptable() waiting for the response rather than reading the command packet as a response. The easiest way to trigger the problem is to run the following cd /sys/device/vio/71000004 while :; cat pcrs >/dev/null; done And press Ctrl-C. This will then display an error tpm_ibmvtpm 71000004: tpm_transmit: tpm_recv: error -4 followed by several other errors once interaction with the TPM resumes. tpm_ibmvtpm 71000004: A TPM error (101) occurred attempting to determine the number of PCRS.

That probably should've been 5 or 6 separate branches, but by the time I'd realized how large and mixed that bag had become it had been too close to -final to play with rebasing. Some fs/namei.c cleanups there, memdup_user_nul() introduction and switching open-coded instances, burying long-dead code, whack-a-mole of various kinds, several new helpers for ->llseek(), assorted cleanups and fixes from various people, etc. One piece probably deserves special mention - Neil's lookup_one_len_unlocked(). Similar to lookup_one_len(), but gets called without ->i_mutex and tries to avoid ever taking it. That, of course, means that it's not useful for any directory modifications, but things like getting inode attributes in nfds readdirplus are fine with that. I really should've asked for moratorium on lookup-related changes this cycle, but since I hadn't done that early enough... I *am* asking for that for the coming cycle, though - I'm going to try and get conversion of i_mutex to rwsem with ->lookup() done under lock taken shared. There will be a patch closer to the end of the window, along the lines of the one Linus had posted last May - mechanical conversion of ->i_mutex accesses to inode_lock()/inode_unlock()/inode_trylock()/ inode_is_locked()/inode_lock_nested().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to allow panic actions to be processed, the ipmi watchdog driver sets a new timeout value on panic. The 255s timeout was designed to allow kdump and others actions on panic, as in http://lkml.iu.edu/hypermail/linux/kernel/0711.3/0258.html This is counter-intuitive for a end-user who sets watchdog timeout value to something like 30s and who expects BMC to reset the system within 30s of a panic.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __compat_only_sysfs_link_entry_to_kobj() was unconditionally called for TPM1 chips, which caused crash on Acer C720 laptop where DSM for the ACPI object did not exist. There are two reasons for unwanted behavior: * The code did not check whether __compat_only_sysfs_link_entry_to_kobj() returned -ENOENT. This is OK. It just meanst that ppi is not available. * The code did not clean up properly. Compat link should added only after all other init is done. This patch sorts out these issues.
