+Subject: [PATCH] libblkid: care about unsafe chars in cache
+
+The high-level libblkid API uses /run/blkid/blkid.tab cache to
+store probing results. The cache format is
+
+ <device NAME="value" ...>devname</device>
+
+and unfortunately the cache code does not escape quotation marks:
+
+ # mkfs.ext4 -L 'AAA"BBB'
+
+ # cat /run/blkid/blkid.tab
+ ...
+ <device ... LABEL="AAA"BBB" ...>/dev/sdb1</device>
+
+such string is later incorrectly parsed and blkid(8) returns
+nonsenses. And for use-cases like
+
+ # eval $(blkid -o export /dev/sdb1)
+
+it's also insecure.
+
+Note that mount, udevd and blkid -p are based on low-level libblkid
+API, it bypass the cache and directly read data from the devices.
+
+The current udevd upstream does not depend on blkid(8) output at all,
+it's directly linked with the library and all unsafe chars are encoded by
+\x<hex> notation.
+
+ # mkfs.ext4 -L 'X"`/tmp/foo` "' /dev/sdb1
+ # udevadm info --export-db | grep LABEL
+ ...
+ E: ID_FS_LABEL=X__/tmp/foo___
+ E: ID_FS_LABEL_ENC=X\x22\x60\x2ftmp\x2ffoo\x60\x20\x22
