  "message": "KEYS: Fix __key_link_end() quota fixup on error\n\nFix __key_link_end()\u0027s attempt to fix up the quota if an error occurs.\n\nThere are two erroneous cases: Firstly, we always decrease the quota if\nthe preallocated replacement keyring needs cleaning up, irrespective of\nwhether or not we should (we may have replaced a pointer rather than\nadding another pointer).\n\nSecondly, we never clean up the quota if we added a pointer without the\nkeyring storage being extended (we allocate multiple pointers at a time,\neven if we\u0027re not going to use them all immediately).\n\nWe handle this by setting the bottom bit of the preallocation pointer in\n__key_link_begin() to indicate that the quota needs fixing up, which is\nthen passed to __key_link() (which clears the whole thing) and\n__key_link_end().\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
