2016-07-15rules: UDEV_DISABLE_PERSISTENT_STORAGE_RULES_FLAG property (#3714)Rusty Bird
Sometimes, the persistent storage rules should be skipped for a subset of devices. For example, the Qubes operating system prevents dom0 from parsing untrusted block device content (such as filesystem metadata) by shipping a custom 60-persistent-storage.rules, patched to bail out early if the device name matches a hardcoded pattern. As a less brittle and more flexible alternative, this commit adds a line to the two relevant .rules files which makes them test the value of the UDEV_DISABLE_PERSISTENT_STORAGE_RULES_FLAG device property, modeled after the various DM_UDEV_DISABLE_*_RULES_FLAG properties.
2016-07-08rules: block: add support for pmem devices (#3683)bgbhpe
Persistent memory devices can be exposed as block devices as /dev/pmemN and /dev/pmemNs. pmemN is the raw device and is byte-addressable from within the kernel and when mmapped by applications from a DAX-mounted file system. pmemNs has the block translation table (BTT) layered on top, offering atomic sector/block access. Both pmemN and pmemNs are expected to contain file systems. blkid(8) and lsblk(8) seem to correctly report on pmemN and pmemNs. systemd v219 will populate /dev/disk/by-uuid/ when, for example, mkfs is used on pmem, but systemd v228 does not. Add pmem to the whitelist.
2016-06-10rules: block - add scm block devices to whitelist (#3494)Lennart Poettering
Since the introduction of the whitelist in 60-persistent-storage.rules block device symlinks are no longer created for scm block devices. Add scm to the whitelist. Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com>
2016-05-19rules: add /dev/disk/by-partuuid symlinks also for dos partition tablesUwe Kleine-König
blkid reports PARTUUID values also for partitions that are defined by a dos partitioning scheme. Instead of limiting the partitioning scheme to "gpt or dos" just drop the test for the partitioning scheme and trust blkid to do the right thing.

Do not skip the persistent storage rules for cciss devices
2015-06-10rules: re-add cciss rulesAlex Crawford
The original commit (1aff206) doesn't explain why these were removed. This adds them back since they are in fact needed.
2015-06-08rules: whitelist xvd* devicesAlex Crawford
Xen disks need to be whitelisted as well.
2015-06-03Add /dev/xvd* to 60-persistent-storage whitelistEd Swierk
Without this, systemd-udevd does not create persistent storage symlinks for xen block devices.

These are handled by a different driver than MemoryStick Pro.

2015-03-12rules: move block device rules to its own rules fileKay Sievers
2015-03-12rules: storage - relace blacklist with explicit whitelistKay Sievers
Newly added kernel drivers repeatedly pass our blacklist and cause trouble for the devices, because they do not expect to be examined by udev's default rules which include blkid. This turns the blacklist into a whitelist. Device type which need support for additional symlinks need to be added to the whitelist now. Note, that the by-id, by-path symlinks are only intended for hotpluggable devices. There is no reason for exotic, or for statically configured devices to provide them.
2015-02-13rules: simplify mmc RPMB handlingMartin Pitt
We don't actually want a by-path/ symlink for MMC RPMB devices, so just add them to the blacklist. This will prevent creating wrong by-path links and blkid'ing those.
2015-02-13rules: Fix by-path of mmc RPMB partitions and don't blkid themMartin Pitt
Linux 3.10+ exposes RPMB (Replay Protected Memory Block) partitions of MMC devices [1] ; trying to read them with blkid or other unspecific means will cause kernel buffer I/O errors and timeouts. So don't run blkid on these. Also ensure that /dev/disk/by-path creates proper symlinks and exposes the -rpmb partition separately, instead of letting the "normal" partition symlink point to the rpbm device (this is a race condition).

2014-03-11gpt-auto-generator: rename root device node symlink to /dev/gpt-auto-rootLennart Poettering
Before it was placed in /dev/disk/by-id, which makes it a bit too much API. However, it's mostly an implementation detail for now, hence move it out of the stable block device dir.

2014-02-05udev: add zram to the list of devices inappropriate for symlinksJóhann B. Guðmundsson
udev seems to have a race condition with swapon to see which can open /dev/zram0 first, causing swapon to fail. Seems to be most noticeable on arm devices one out of every 7 times or something.
