2019-06-20block: remove the bi_phys_segments field in struct bioChristoph Hellwig5-10/+2
We only need the number of segments in the blk-mq submission path. Remove the field from struct bio, and return it from a variant of blk_queue_split instead of that it can passed as an argument to those functions that need the value. This also means we stop recounting segments except for cloning and partial segments. To keep the number of arguments in this how path down remove pointless struct request_queue arguments from any of the functions that had it and grew a nr_segs argument.

For all callers of fsnotify_{unlink,rmdir}(), we made sure that d_parent and d_name are stable.

2019-06-20fsnotify: move fsnotify_nameremove() hook out of d_delete()Amir Goldstein1-0/+2
d_delete() was piggy backed for the fsnotify_nameremove() hook when in fact not all callers of d_delete() care about fsnotify events. For all callers of d_delete() that may be interested in fsnotify events, we made sure to call one of fsnotify_{unlink,rmdir}() hooks before calling d_delete(). Now we can move the fsnotify_nameremove() call from d_delete() to the fsnotify_{unlink,rmdir}() hooks. Two explicit calls to fsnotify_nameremove() from nfs/afs sillyrename are also removed. This will cause a change of behavior - nfs/afs will NOT generate an fsnotify delete event when renaming over a positive dentry. This change is desirable, because it is consistent with the behavior of all other filesystems. Signed-off-by: Amir Goldstein <amir73il@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz>

We would like to move fsnotify_nameremove() calls from d_delete() into a higher layer where the hook makes more sense and so we can consider every d_delete() call site individually. Start by creating empty hook fsnotify_{unlink,rmdir}() and place them in the proper VFS call sites. After all d_delete() call sites will be converted to use the new hook, the new hook will generate the delete events and fsnotify_nameremove() hook will be removed.

2019-06-20regulator: da9061/62: Adjust LDO voltage selection minimum valueFelix Riemann1-0/+3
According to the DA9061 and DA9062 datasheets the LDO voltage selection registers have a lower value of 0x02. This applies to voltage registers VLDO1_A, VLDO2_A, VLDO3_A and VLDO4_A. This linear offset of 0x02 was previously not observed by the driver, causing the LDO output voltage to be systematically lower by two steps (= 0.1V). This patch fixes the minimum linear selector offset by setting it to a value of 2 and increases the n_voltages by the same amount allowing voltages in the range 0x02 -> 0.9V to 0x38 -> 3.6V to be correctly selected. Also fixes an incorrect calculaton for the n_voltages value in the regulator LDO2. These fixes effect all LDO regulators for DA9061 and DA9062.

2019-06-20x86/e820, ioport: Add a new I/O resource descriptor IORES_DESC_RESERVEDLianbo Jiang1-0/+1
When executing the kexec_file_load() syscall, the first kernel needs to pass the e820 reserved ranges to the second kernel because some devices (PCI, for example) need them present in the kdump kernel for proper initialization. But the kernel can not exactly match the e820 reserved ranges when walking through the iomem resources using the default IORES_DESC_NONE descriptor, because there are several types of e820 ranges which are marked IORES_DESC_NONE, see e820_type_to_iores_desc(). Therefore, add a new I/O resource descriptor called IORES_DESC_RESERVED to mark exactly those ranges. It will be used to match the reserved resource ranges when walking through iomem resources.

2019-06-20coresight: Use platform agnostic namesSuzuki K Poulose1-1/+24
So far we have reused the name of the "platform" device for the CoreSight device. But this is not very intuitive when we move to ACPI. Also, the ACPI device names have ":" in them (e.g, ARMHC97C:01), which the perf tool doesn't like very much. This patch introduces a generic naming scheme, givin more intuitive names for the devices that appear on the CoreSight bus. The names follow the pattern "prefix" followed by "index" (e.g, etm5). We maintain a list of allocated devices per "prefix" to make sure we don't allocate a new name when it is reprobed (e.g, due to unsatisifed device dependencies). So, we maintain the list of "fwnodes" of the parent devices to allocate a consistent name. All devices except the ETMs get an index allocated in the order of probing. ETMs get an index based on the CPU they are attached to. TMC devices are named using "tmc_etf", "tmc_etb", and "tmc_etr" prefixes depending on the configuration of the device. The replicators and funnels are not classified as dynamic/static anymore. One could easily figure that out by checking the presence of "mgmt" registers under sysfs.

2019-06-20coresight: Use fwnode handle instead of device namesSuzuki K Poulose1-2/+2
We rely on the device names to find a CoreSight device on the coresight bus. The device name however is obtained from the platform, which is bound to the real platform/amba device. As we are about to use different naming scheme for the coresight devices, we can't rely on the platform device name to find the corresponding coresight device. Instead we use the platform agnostic "fwnode handle" of the parent device to find the devices. We also reuse the same fwnode as the parent for the Coresight device we create.

2019-06-19keys: Cache result of request_key*() temporarily in task_structDavid Howells2-0/+12
If a filesystem uses keys to hold authentication tokens, then it needs a token for each VFS operation that might perform an authentication check - either by passing it to the server, or using to perform a check based on authentication data cached locally. For open files this isn't a problem, since the key should be cached in the file struct since it represents the subject performing operations on that file descriptor. During pathwalk, however, there isn't anywhere to cache the key, except perhaps in the nameidata struct - but that isn't exposed to the filesystems. Further, a pathwalk can incur a lot of operations, calling one or more of the following, for instance: ->lookup() ->permission() ->d_revalidate() ->d_automount() ->get_acl() ->getxattr() on each dentry/inode it encounters - and each one may need to call request_key(). And then, at the end of pathwalk, it will call the actual operation: ->mkdir() ->mknod() ->getattr() ->open() ... which may need to go and get the token again. However, it is very likely that all of the operations on a single dentry/inode - and quite possibly a sequence of them - will all want to use the same authentication token, which suggests that caching it would be a good idea. To this end: (1) Make it so that a positive result of request_key() and co. that didn't require upcalling to userspace is cached temporarily in task_struct. (2) The cache is 1 deep, so a new result displaces the old one. (3) The key is released by exit and by notify-resume. (4) The cache is cleared in a newly forked process.

2019-06-19fanotify: update connector fsid cache on add markAmir Goldstein1-1/+3
When implementing connector fsid cache, we only initialized the cache when the first mark added to object was added by FAN_REPORT_FID group. We forgot to update conn->fsid when the second mark is added by FAN_REPORT_FID group to an already attached connector without fsid cache.

2019-06-19locks: eliminate false positive conflicts for write leaseAmir Goldstein1-2/+2
check_conflicting_open() is checking for existing fd's open for read or for write before allowing to take a write lease. The check that was implemented using i_count and d_count is an approximation that has several false positives. For example, overlayfs since v4.19, takes an extra reference on the dentry; An open with O_PATH takes a reference on the dentry although the file cannot be read nor written. Change the implementation to use i_readcount and i_writecount to eliminate the false positive conflicts and allow a write lease to be taken on an overlayfs file. The change of behavior with existing fd's open with O_PATH is symmetric w.r.t. current behavior of lease breakers - an open with O_PATH currently does not break a write lease. This increases the size of struct inode by 4 bytes on 32bit archs when CONFIG_FILE_LOCKING is defined and CONFIG_IMA was not already defined.
